The role of trader positions in spot and futures prices for WTI  

Science Journals Connector (OSTI)

Abstract We extend the analysis of causal relations between trader positions and oil prices and the process of price discovery by estimating a cointegrating vector autoregression (CVAR) model that expands the cash-and-carry relation between spot and futures prices to quantify long- and short-run relations among oil prices, trader positions, interest rates, and oil inventories. Results indicate that oil inventories and trader positions are needed to generate cointegration between spot and futures prices. The presence of trader positions and oil inventories suggest that both play a role in price discovery. Furthermore, the cointegrating relation for price loads into the equation for both oil prices and trader positions. This suggests a bi-directional simultaneous adjustment process between oil prices and trader positions. This expands the unidirectional causal relation from oil prices to trader positions that is generated by previous studies. Additional results suggest that price discovery occurs in the market for heavily traded near-month futures contracts, but discovery for thin far-month futures markets occurs in the spot market. Together, these results suggest mechanisms by which speculation could affect oil prices but the results presented here are moot regarding their effects.

The effect of the financial sector on the evolution of oil prices: Analysis of the contribution of the futures market to the price discovery process in the WTI spot market  

Science Journals Connector (OSTI)

The aim of this article is to empirically measure the contribution of the futures market to the price discovery process in the spot market for benchmark crude oils, specifically that for West Texas Intermediate (WTI). For this purpose, we test the hypothesis that the recent evolution of the financial markets has affected the future oil market so as to increase its contribution to the price discovery process of the spot market. We modeled the relation between WTI spot and future prices as a cointegration relation. By using the Kalman filter technique, it was possible to obtain a time-varying measure of the contribution of future markets to the price discovery mechanism. The results show that in the case of WTI, the contribution of the futures market has been increasing, especially between 2003 and 2008 and then again after the start of 2009, evidencing the growing importance of factors particular to the financial markets in determining oil prices in recent years. During 2009, the spot prices adjusted to agents' future expectations rather than to the current supply and demand conditions.

WTI Crude Oil Price: Base Case and 95% Confidence Interval  

Gasoline and Diesel Fuel Update (EIA)

7 7 Notes: Spot WTI prices broke $35 and even $36 per barrel in November as anticipated boosts to world supply from OPEC and other sources failed to find much realization in actual stocks data. The idea that stocks are still languishing at below-normal levels is particularly persuasive when one views current levels (for key consuming regions) relative to "normal" values which account for the long-term trend in OECD stocks. We believe that monthly average WTI prices will stay around $30 per barrel for the first part of 2001. This is a noticeable upward shift in our projected average prices from even a month ago. The shift reflects greater emphasis on the lack of stock builds and less emphasis on the assumption that supply from OPEC and non-OPEC suppliers may be exceeding demand by 1-2

WTI Crude Oil Prices Are Expected To Remain Relatively High Through At  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: As we just saw, one of the primary factors impacting gasoline price is the crude oil price. This graph shows monthly average spot West Texas Intermediate crude oil prices. Spot WTI crude oil prices broke $36 per barrel in November briefly as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. Crude oil prices are expected to be about $30 per barrel for the rest of this year, but note the uncertainty bands on this projection. They give an indication of how difficult it is to know what these prices are going to do. Also, EIA does not forecast volatility. This relatively flat forecast could be correct on average, with wide swings around the base line. With the EIA forecast for crude prices staying high this year,

A technical look at the WTI incinerator  

SciTech Connect

EPA has granted Waste Technologies Industries (WTI) temporary authorization to burn hazardous waste in its new incinerator in East Liverpool, Ohio. The approval is based on preliminary data showing that the incinerator was able to meet EPA`s emission standards for dioxins and furans in tests run this summer. WTI is allowed to continue burning waste pending final evaluation of its March 1993 performance tests. The action marks yet another hurdle cleared by WTI in its 11-year effort to construct and operate a commercial hazardous waste incinerator. The facility`s long-standing predicament as a target for environmental and public interest groups has made it the subject of numerous lawsuits and many legal reviews. In this article, however, we focus on the technical aspects of the system. The WTI incinerator is described in {open_quotes}Performance Testing of a Rotary Kiln Incinerator,{close_quotes} a paper by Alfred Sigg of Von Roll, Incorporated (Norcross, Georgia). The paper was presented at the 1993 Incineration Conference, which was held in Knoxville, Tennessee on May 3-7, 1993. 1 fig., 2 tabs.

9 9 Notes: Spot WTI prices broke $35 and even $36 per barrel in November as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. The recent decline in prices seems to be more the result of an unraveling of speculative pressures than a change in underlying fundamentals. Prices had been running higher than supply/demand fundamentals would have indicated throughout the fall months as a result of rising Mideast tensions, concern over the adequacy of distillate supplies, and expectations of Iraqi supply interruptions. But Mideast tensions seemed to ease in December and the market appeared to perceive a quick return of Iraqi crude oil supplies at full capacity.

Causality and volatility spillovers among petroleum prices of WTI, gasoline and heating oil in different locations  

Science Journals Connector (OSTI)

This paper examines the time series properties of daily spot and futures prices for three petroleum types traded at five commodity centers within and outside the United States. Examining five combinations of the spot and futures prices by petroleum type and trading center, the cointegration tests of each of these five groups suggest that spot and futures contracts offer little room for long-run commodity portfolio diversification. In the West Texas Intermediate (WTI) crude-oil group, the VEC model indicates that the New York Mercantile Exchange (NYMEX) 1-month futures price has the upper hand in terms of directional causality and volatility spillovers. In the NYMEX gasoline system, there are bi-directional causality relationships among all the gasoline spot and futures prices, but the spot price produces the greatest spillover. In the NYMEX heating oil system, information transmission and predictability among the spot, 1- and 3-month futures are found to be particularly strong and significant. In the international gasoline spot market, contrary to the world crude-oil market, there is no apparent world gasoline spot leader for the gasoline spot prices.

Speculative trading and oil price dynamic: A study of the WTI market  

Science Journals Connector (OSTI)

The aim of this paper is to study the oil price dynamic in West Texas Intermediate (WTI) market in the US. By using statistical and econometric tools, we first attempt to identify the long term relationship between WTI spot prices and the prices of futures contracts on the New York Mercantile Exchange (NYMEX). Subsequently we model the short term dynamic between these two prices and this analysis points up several breaks. On this basis, a short term Markov Switching Vectorial Error Correction model (MS-VECM) with two distinct states (standard state and crisis state) has been estimated. Finally we introduce the volumes of transactions observed on the NYMEX for the WTI contracts and we estimate the influence of the non-commercial players. We conclude that the hypothesis of an influence of non-commercial players on the probability for being in the crisis state cannot be rejected. In addition, we show that the rise in liquidity of the first financial contracts, as measured by the volume of open interest, is a key element to understand the dynamics in market prices.

Thermal diffusion in Au?WTi?Pd metallization on silicon  

Science Journals Connector (OSTI)

This paper presents the results of investigation of thermal diffusion in Au?Wti?Pd metallization on (111) n-Si. Thin films were deposited by dc sputtering to the thickness of 50 (Pd), 100–200 (WTi) and 70–200 nm (Au). After deposition the samples were subjected to thermal treatments vacuum 1 × 10?5 mbar, at temperatures up to 600°C. Characterization included RBS, AES, XRD and SEM structural analysis and sheet resistivity measurements. During annealing up to 450°C diffusion occurs only at the Pd?Si interface, at 500°C other components interdiffuse at isolated areas of the samples and at 600°C there is total interdiffusion on components. Thermal degradation oftthe \\{WTi\\} diffusion barrier is enhanced by the growth of Pd2Si phase, during which silicon is released from the substrate and mechanical stress is introduced. Better diffusion barrier properties were obtained when \\{WTi\\} films were deposited in nitrogen or oxygen atmosphere.

Can GARCH-class models capture long memory in WTI crude oil markets?  

Science Journals Connector (OSTI)

This paper investigates the issue whether GARCH-type models can well capture the long memory widely existed in the volatility of WTI crude oil returns. In this frame, we model the volatility of spot and futures returns employing several GARCH-class models. Then, using two non-parametric methods, detrended fluctuation analysis (DFA) and rescaled range analysis (R/S), we compare the long memory properties of conditional volatility series obtained from GARCH-class models to that of actual volatility series. Our results show that GARCH-class models can well capture the long memory properties for the time scale larger than a year. However, for the time scale smaller than a year, the GARCH-class models are misspecified.

Comparison of \\{WTi\\} and WTi(N) as diffusion barriers for Al and Cu metallization on Si with respect to thermal stability and diffusion behavior of Ti  

Science Journals Connector (OSTI)

Abstract The thermal stability of \\{WTi\\} and WTi(N) as diffusion barriers for Al and Cu metallization on Si (1 0 0) was investigated by time of flight secondary ion mass spectrometry (ToF-SIMS) depth profiling, X-ray diffraction (XRD), electron microscopy (SEM and TEM) and X-ray photoelectron spectroscopy (XPS). For both, Al and Cu, Ti diffusion out of \\{WTi\\} into the metal was proved to occur at elevated temperatures (400 °C for Al and 600 °C for Cu) which further results in barrier film failure. Nitrogen incorporation into \\{WTi\\} leads to an elimination of the Ti diffusion and consequently to a better thermal stability of the barrier film. It is shown that besides crystal structure, Ti diffusion into the metallization is an essential factor of the barrier failure mechanism. The failure temperature for Al is lower than for Cu.

Real-time curvature and optical spectroscopy monitoring of magnetron-sputtered \\{WTi\\} alloy thin films  

Science Journals Connector (OSTI)

Abstract \\{WTi\\} thin films are known as potential adhesion promoters and diffusion barriers. \\{WTi\\} thin films were deposited by magnetron sputtering from an alloyed target (W:Ti ~ 70:30 at.%). Real-time surface differential reflectance (SDR) spectroscopy and wafer-curvature measurements were performed during deposition to study the growth and the film continuity threshold. SDR measurements during \\{WTi\\} deposition allow the determination of the change in reflectivity of p-polarized light (at Si substrate Brewster's angle) between \\{WTi\\} film and Si substrate in order to monitor layer growth. The comparison between experimental and simulated \\{WTi\\} SDR signals assuming a homogeneous and continuous layer growth shows that film continuity is ensured beyond a thickness of 4.5 ± 0.2 nm. Real-time wafer-curvature measurements allow the determination of the intrinsic stress development in the film. Two regimes are noticed during the growth up to the development of a compressive steady state stress. The early stages of growth are rather complicated and divided into sub-regimes with similar boundaries revealed by both in situ techniques. Deposition of an interfacial continuous layer different from \\{WTi\\} bulk is suggested by both in situ techniques below a thickness of 4.5 nm.

Wear behaviour of tool steels with added (WTi)C particles  

Science Journals Connector (OSTI)

The volume fraction of hard second phase particles in tool steels is limited by the formation of large interconnected carbides on solidification that embrittle the alloy. In this work, a novel carbide master alloy, FeWTiC, which contains (WTi)C particles, was used to increase the volume fraction of carbide in an H21 hot work die steel (0.3%C, 9%W, 3%Cr). Additions of up to 5 vol.% (WTi)C were successfully made to the vacuum melted steel, producing a homogeneous distribution of (WTi)C throughout the microstructure. TEM and fracture testing confirmed that a good bond existed between the (WTi)C and martensitic matrix. Wear testing was undertaken using pure sliding against an M2 tool steel counterface, in a block on ring configuration, in the load range of 54–254 N and a sliding speed of 0.98 m/s. At 54 N, an increase in volume fraction of (WTi)C gave a reduction in wear coefficient, associated with predominantly oxidational wear, with associated ploughing of the tool steel surface by oxide particles. At higher loads the addition of (WTi)C did not result in reduced wear rates. In addition to oxidational wear, delamination occurred, frequently initiated at the matrix/M6C particle interface. Fracture of the (WTi)C became more common as the load increased. A 1% (WTi)C marginally reduced the depth of deformation compared to the H21, but further additions had little additional effect. Detailed TEM indicated the complex interaction between oxide formation and surface deformation of the tool steel. The relationship between wear mechanism and microstructure is discussed.

Development of WTI and turbidity estimation model using SMA — application to Kushiro Mire, eastern Hokkaido, Japan  

Science Journals Connector (OSTI)

A new water-turbidity index (WTI) based on multispectral images was developed and tested at Kushiro Mire, eastern Hokkaido, Japan. An algorithm for turbidity estimation was developed and applied to Landsat TM images to monitor the turbid water on the mire surface during the snow-melting season. We used spectral mixture analysis (SMA) to produce a turbidity estimation model. The SMA “unmixes” a mixed pixel determining the fractions due to each spectral end member. In this study, we used four end members (1, alder; 2, reed; 3, high-concentration turbid water (485 ppm); 4, low-concentration turbid water (10 ppm) measured in the test site. The WTI was determined by the following equation: WTI=amax/(amax+amin), where amax is abundance of high-concentration turbid water and amin is abundance of low-concentration turbid water. The end-member spectra of alder and reed were measured in the laboratory using specimens collected at the test site. The spectrum of turbid water was measured at the test sites. The relative abundance of each end member was estimated based on this spectral information using SMA. The same formula was applied to Landsat TM images. Then we applied the WTI equation to the end-member images to obtain a WTI map. In the mire wetland region, turbid water spreads under alder trees and reed grasses. To verify our turbidity estimation method based on WTI under these conditions, we constructed a small experimental wetland consisting of mixed stands of alder and reed. WTI was calculated from the mixed spectrum of this “artificial wetland” and the regression curve for the relation between WTI and the actual turbidity was determined (R2=.91). Finally, this regression equation was used to derive a turbidity map from the WTI image.

Exploring the WTI crude oil price bubble process using the Markov regime switching model  

Science Journals Connector (OSTI)

Abstract The sharp volatility of West Texas Intermediate (WTI) crude oil price in the past decade triggers us to investigate the price bubbles and their evolving process. Empirical results indicate that the fundamental price of WTI crude oil appears relatively more stable than that of the market-trading price, which verifies the existence of oil price bubbles during the sample period. Besides, by allowing the WTI crude oil price bubble process to switch between two states (regimes) according to a first-order Markov chain, we are able to statistically discriminate upheaval from stable states in the crude oil price bubble process; and in most of time, the stable state dominates the WTI crude oil price bubbles while the upheaval state usually proves short-lived and accompanies unexpected market events.

Influence of target structure on film stress in WTi sputtering  

SciTech Connect

In this report, the effect of sputtering target microstructure on the deposited film stress was investigated. By controlling the metallurgical process, two types of W-10wt%Ti target constituents, namely single-phase and multiple-phase WTi, were prepared. The former one was composed of W-rich ({beta}Ti,W) phase only, the latter one was with W, W-rich ({beta}Ti,W) and Ti-rich ({beta}Ti,W) phases. The stress of the films deposited on 12.7 cm diameter silicon oxide wafers from the single-phase target tends to be more compressive than that from the multiple-phase target. By increasing wafer temperature, the compressive stress was linearly decreased. In addition, the level of film stress was also affected by the film thickness and other sputtering parameters. To understand the causes for the differences in film stress between the multiple-phase and single-phase derived films, an evaluation of the film structure using a field-emission scanning electron microscope (FE-SEM) and mechanical testing using a nano-indentation instrument were performed. Finer domains with denser laminar structure were observed on the films deposited from the single-phase target. However, no significant difference in mechanical properties was found between these two from the nano-indentation measurements. It is envisioned that the more uniform solid solution between the W and Ti in the films obtained by sputtering the single-phase targets generates a higher compressive stress when deposited on the silicon oxide wafers resulting in a higher compressive stress.

Influence of a d.c. substrate bias on the resistivity, composition, crystallite size and microstrain of \\{WTi\\} and WTi-N films  

Science Journals Connector (OSTI)

The influence of a d.c. substrate bias on the properties of \\{WTi\\} and WTi-N films deposited by r.f. magnetron sputtering has been studied. The bias voltage was varied from 0 to ?200 V. The \\{WTi\\} films structure is b.c.c. W with the presence of the h.c.p. Ti phase at low bias (0 to ?50 V). For the WTi-N films, the structure is f.c.c. TiN at low bias and b.c.c. W + f.c.c. TiN at high bias (?100 V to ?200 V). Both films exhibit the columnar morphology. The titanium fraction in the films is lower than in the target and decreases when the bias increases owing to a titanium preferential resputtering caused by the ion bombardment of the substrate. The same behaviour is found for the film resistivity which diminishes when the bias is increased whereas the crystallite size increases. The microstrains have a more complex variation with the bias.

Effects of the pulse duration in laser modification of nano-sized WTi film on Si  

Science Journals Connector (OSTI)

A study of morphological and composition changes of the WTi/Si system induced by nanosecond and picosecond laser pulses is presented. A 190 nm thick WTi film was deposited on a silicon substrate of n-type (100). The pulsed laser systems used were: nanosecond TEA CO2 laser (emission, 10.6 µm; pulse FWHM; pulse duration 120 ns) and picosecond Nd:YAG laser (emission, 532 nm; pulse FWHM; pulse duration 40 ps). During experiments the used fluences (?) had similar values, ?1 = 20 J  cm ? 2 in case of the TEA CO2 laser and ?2 = 16 J cm ? 2 for the Nd:YAG laser. The laser-induced morphological and composition modifications showed a dependence on pulse duration. Generally, the following morphological changes were observed: (i) ablation/exfoliation of the WTi thin film, (ii) appearance of hydrodynamic features such as resolidified material, and (iii) formation of nano-sized grains and globules. Overall morphological modifications were more pronounced after the picosecond laser action. The surface composition analysis showed a quite different distribution of sample components depending on the pulse duration. Formation of the silicon dioxide (SiO2) was recorded only in the case of irradiation of the WTi/Si system by picosecond laser pulses.

Natural Gas Spot Prices:  

Gasoline and Diesel Fuel Update (EIA)

4 of 26 4 of 26 Notes: Spot wellhead prices last summer averaged well over $4.00 per thousand cubic feet during a normally low-price season. During the fall, these prices stayed above $5.00 per thousand cubic feet, more than double the year-ago average price. In January, the spot wellhead price averaged a record $8.98 per thousand cubic feet. Spot prices at the wellhead have never been this high for such a prolonged period. The chief reason for these sustained high gas prices was, and still is, uneasiness about the supply situation. Concern about the adequacy of winter supplies loomed throughout most of the summer and fall as storage levels remained significantly depressed. Last December, the most severe assumptions about low storage levels became real, when the spot price

WTi thin films were prepared from an alloyed target (W:Ti ? 70:30?at. %) by magnetron sputtering. Body-centered cubic W x T i 1 ? x solid solutions with a { 110 } fiber texture and columnar grains have been produced with 0.75 WTi thin films is about 60 ? 200 ? ? ? ? cm depending on the film thickness and microstructure (sputtering conditions). For both ultra-thin (9.5?nm) and thin (180?nm) films a stress transition from compressive to tensile is observed as the working pressure increases. The process-structure-property relations of the WTi ultra-thin and thin films are discussed in relation with the state of the art.

Spot Distillate & Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

mid-January, 2000. WTI crude oil price rose about $17 per mid-January, 2000. WTI crude oil price rose about $17 per barrel or 40 cents per gallon from its low point in mid February 1999 to January 17, 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and the beginning of a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, distillate spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled higher as the New York Harbor market began to draw on product from other areas. They closed at 83 cents per gallon, an increase of 11 cents from the prior Friday. Crude oil had risen about 4 cents from

Modeling dynamic conditional correlations in WTI oil forward and futures returns  

Science Journals Connector (OSTI)

This paper estimates the dynamic conditional correlations in the daily returns on West Texas Intermediate (WTI) oil forward and futures prices from 3 January 1985 to 16 January 2004, using recently developed multivariate conditional volatility models. We find that the dynamic conditional correlations can vary dramatically, being negative in four of ten cases and being close to zero in another five cases. Only in the case of the dynamic volatilities of the three-month and six-month futures returns is the range of variation relatively narrow, namely (0.832, 0.996).

Minimum variance hedging with bivariate regime-switching model for WTI crude oil  

Science Journals Connector (OSTI)

This paper proposes a four-regime bivariate Markov regime-switching model to estimate the daily time-varying minimum variance hedge ratios for West Texas Intermediate (WTI) crude oil, and evaluates its in- and out-of-sample hedging performances with two-regime model, CC-GARCH, TVC-GARCH, and OLS models. Empirical results reveal that the four-regime Markov switching model outperforms the other models for both in- and out-of-sample hedging performance. Based on Hansen’s SPA test (2005), the four-regime model significantly outperforms the other models for only in-sample hedging.

Treatment of \\{WTi\\} Contacts on silicon with low energy argon ions  

Science Journals Connector (OSTI)

Thin layers of \\{WTi\\} were deposited by ion sputtering on p- and n-type Si(111) substrates. The initial target composition is 90: 10 W: Ti, the thicknesses of the layers were 200 and 350 nm, and the layers were grown at a rate of 10 nm min?1. After deposition, the contacts were bombarded by backsputtering with Ar+ ions at 3.5 keV. The as-deposited layers from a surface barrier on both substrates (0.62 V on n-Si and 0.66 V on p-Si). During ion bombardment, to doses from 0.5 × 1018 to 5 × 1018 ions cm?2, the barrier is reduced until the contacts become non-rectifying. The main effect during bombardment is sputtering and development of topography (scanning electron microscopy analysis), but there is also a shallow mixing at the interface (as shown by Rutherford backscattering and X-ray analyses). During annealing at 800 °C, pronounced metal-silicon interdiffusion is observed in bombarded specimens and not in unbombarded specimens. So-formed silicides renew the rectifying properties of \\{WTi\\} contacts, with an effective barrier height of 0.66–0.69 V on n-Si.

Surface modification of a \\{WTi\\} thin film on Si substrate by nanosecond laser pulses  

Science Journals Connector (OSTI)

Interaction of a nanosecond transversely excited atmospheric (TEA) CO2 laser, operating at 10.6 ?m, with tungsten–titanium thin film (190 nm) deposited on silicon of n-type (1 0 0) orientation, was studied. Multi-pulse irradiation was performed in air atmosphere with laser energy densities in the range 24–49 J/cm2. The energy absorbed from the laser beam was mainly converted to thermal energy, which generated a series of effects. The following morphological changes were observed: (i) partial ablation/exfoliation of the \\{WTi\\} thin film, (ii) partial modification of the silicon substrate with formation of polygonal grains, (iii) appearance of hydrodynamic features including nano-globules. Torch-like plumes started appearing in front of the target after several laser pulses.

Auto-correlated behavior of WTI crude oil volatilities: A multiscale perspective  

Science Journals Connector (OSTI)

In this paper, we investigate the long-range auto-correlated behavior of WTI crude oil volatility series employing multifractal detrended fluctuation analysis. Our findings show that the for small time scales, the auto-correlations of volatilities were multifractal while for large time scales, the auto-correlations were nearly monofractal. Based on multiscale analysis, we also investigate the dynamics of auto-correlations for different intervals of time scales and find that several shocks could make significant effects on the auto-correlated behaviors for small time scales. Analyzing the dynamics of multifractality degrees of auto-correlations for small time scales, we find that the stronger auto-correlations were always related to the lower degrees of multifractality. At last, we have discussions on the determination factors of price behavior, the predictive implications of scaling behavior in volatilities for oil markets and the reasons why long-range auto-correlations of volatility were always strong for both small time scales and large time scales. Our results are very important theoretically and practically.

WTI crude oil Futures in portfolio diversification: The time-to-maturity effect  

Science Journals Connector (OSTI)

The aim of the paper is to analyze the diversification effect brought by crude oil Futures contracts, the most liquid commodity Futures, into a portfolio of stocks. The studies that have documented the very low- and essentially negative-correlations between commodities and equities typically rely on normally distributed returns, which is not the case for crude oil Futures and stocks indexes. Moreover, the particular time-to-maturity chosen for the Future contract used as an investment vehicle is an important matter that needs to be addressed, in presence of forward curves switching between backwardation and contango shapes. Our goal in this paper is twofold: (a) we introduce copula functions to have a better representation of the dependence structure of oil Futures with equity indexes; (b) using this copula representation, we are able to analyze in a precise manner the “maturity effect” in the choice of crude oil Future contract with respect to its diversification benefits. Our finding is that, in the case of distant maturities Futures, e.g., 18 months, the negative correlation effect is more pronounced whether stock prices increase or decrease. This property has the merit to avoid the hurdles of a frequent roll over while being quite desirable in the current trendless equity markets. Empirical evidence is exhibited on a database comprising the NYMEX WTI crude oil Futures and S&P 500 index over a 15 year-time period.

Testing the weak-form efficiency of the WTI crude oil futures market  

Science Journals Connector (OSTI)

Abstract The weak-form efficiency of energy futures markets has long been studied and empirical evidence suggests controversial conclusions. In this work, nonparametric methods are adopted to estimate the Hurst indexes of the WTI crude oil futures prices (1983–2012) and a strict statistical test in the spirit of bootstrapping is put forward to verify the weak-form market efficiency hypothesis. The results show that the crude oil futures market is efficient when the whole period is considered. When the whole series is divided into three sub-series separated by the outbreaks of the Gulf War and the Iraq War, it is found that the Gulf War reduced the efficiency of the market. If the sample is split into two sub-series based on the signing date of the North American Free Trade Agreement, the market is found to be inefficient in the sub-periods during which the Gulf War broke out. The same analysis on short-time series in moving windows shows that the market is inefficient only when some turbulent events occur, such as the oil price crash in 1985, the Gulf war, and the oil price crash in 2008.

Estimating VaR and ES of the spot price of oil using futures-varying centiles  

Science Journals Connector (OSTI)

This paper illustrates the power of modern statistical modelling in estimating measures of market risk, here applied to the Brent and WTI spot price of oil. Both Value-at-Risk (VaR) and Expected Shortfall (ES) are cast in terms of conditional centiles based upon semi-parametric regression models. Using the GAMLSS statistical framework, we stress the important aspects of selecting a highly flexible parametric distribution (skewed Student's t-distribution) and of modelling both skewness and kurtosis as non-parametric functions of the price of oil futures. Furthermore, an empirical application characterises the relationship between spot oil prices and oil futures - exploiting the futures market to explain the dynamics of the physical market. Our results suggest that NYMEX WTI has heavier tails compared with the ICE Brent. Contrary to the common platitude of the industry, we argue that 'somebody knows something' in the oil business.

Is WTI crude oil market becoming weakly efficient over time?: New evidence from multiscale analysis based on detrended fluctuation analysis  

Science Journals Connector (OSTI)

This paper extends the work in Tabak and Cajueiro [Are the crude oil markets becoming weakly efficient over time, Energy Economics 29 (2007) 28–36] and Alvarez-Ramirez et al. [Short-term predictability of crude oil markets: a detrended fluctuation analysis approach, Energy Economics 30 (2008) 2645–2656]. In this paper, we test for the efficiency of WTI crude oil market through observing the dynamic of local Hurst exponents employing the method of rolling window based on multiscale detrended fluctuation analysis. Empirical results show that short-term, medium-term and long-term behaviors were generally turning into efficient behavior over time. However, in this way, the results also show that the market did not evolve along stable conditions for long times. Multiscale analysis is also implemented based on multifractal detrended fluctuation analysis. We found that the small fluctuations of WTI crude oil market were persistent; however, the large fluctuations had high instability, both in the short- and long-terms. Our discussion is also extended by incorporating arguments from the crude oil market structure for explaining the different correlation dynamics.

Unit root properties of crude oil spot and futures prices  

Science Journals Connector (OSTI)

In this article, we examine whether WTI and Brent crude oil spot and futures prices (at 1, 3 and 6 months to maturity) contain a unit root with one and two structural breaks, employing weekly data over the period 1991–2004. To realise this objective we employ Lagrange multiplier (LM) unit root tests with one and two endogenous structural breaks proposed by Lee and Strazicich [2003. Minimum Lagrange multiplier unit root test with two structural breaks. Review of Economics and Statistics, 85, 1082–1089; 2004. Minimum LM unit root test with one structural break. Working Paper no. 04–17, Department of Economics, Appalachian State University]. We find that each of the oil price series can be characterised as a random walk process and that the endogenous structural breaks are significant and meaningful in terms of events that have impacted on world oil markets.

Natural Gas Spot Price Outlook  

Gasoline and Diesel Fuel Update (EIA)

7 of 17 7 of 17 Notes: Despite signs that domestic natural gas production has begun to turn around (the Texas Railroad Commission now reports year-to-date (through Sep.) gains in Texas gas production of 1.2 percent, compared to a 4.7-percent decline for the same months in 1999 versus 1998) the reality of the U.S. gas market is that supply responses have been too little, too late to prevent record-high spot prices and prospects for very high average prices this winter. We now expect to see peak monthly spot wellhead prices this winter of over $6.00 per thousand cubic feet (mcf) (December). Last month we maintained confidence that conditions would improve enough to keep the $5.10 per mcf recorded in October as the peak for this heating season. With partial data available, a monthly average value of about $5.60 per mcf looks likely for

Retail Price Changes Lag Spot Prices  

Gasoline and Diesel Fuel Update (EIA)

1 1 Notes: While EIA cannot claim to explain all of the factors that drive retail gasoline prices, we have had a fair amount of success in exploring the relationship between wholesale and retail prices. In particular, we have looked closely at the "pass-through" of changes in spot prices to the retail market. This graph shows a weighted national average of spot prices for regular gasoline -both conventional and reformulated (shown in red), and EIA's weekly survey price for retail regular (again both conventional and reformulated). As you can see, spot prices tend to be more volatile (and would be even more so on a daily basis), while these changes are smoother by the time they reach the retail pump. Furthermore, by looking at the peaks, you can see the retail prices seem to lag the spot price changes

Reactor hot spot analysis  

SciTech Connect

The principle methods for performing reactor hot spot analysis are reviewed and examined for potential use in the Applied Physics Division. The semistatistical horizontal method is recommended for future work and is now available as an option in the SE2-ANL core thermal hydraulic code. The semistatistical horizontal method is applied to a small LMR to illustrate the calculation of cladding midwall and fuel centerline hot spot temperatures. The example includes a listing of uncertainties, estimates for their magnitudes, computation of hot spot subfactor values and calculation of two sigma temperatures. A review of the uncertainties that affect liquid metal fast reactors is also presented. It was found that hot spot subfactor magnitudes are strongly dependent on the reactor design and therefore reactor specific details must be carefully studied. 13 refs., 1 fig., 5 tabs.

Hottest spot temperatures in ventilated dry type transformers  

SciTech Connect

The hottest spot temperature allowance to be used for the different insulation system temperature classes is a major unknown facing IEEE Working Groups developing standards and loading guides for ventilated dry type transformers. In 1944, the hottest spot temperature allowance for ventilated dry type transformers was established as 30 C for 80 C average winding temperature rise. Since 1944, insulation temperature classes have increased to 220 C but IEEE standards continue to use a constant 30 C hottest spot temperature allowance. IEC standards use a variable hottest spot temperature allowance from 5 to 30 C. Six full size test windings were manufactured with imbedded thermocouples and 133 test runs performed to obtain temperature rise data. The test data indicated that the hottest spot temperature allowance used in IEEE standards for ventilated dry type transformers above 500 kVA is too low. This is due to the large thermal gradient from the bottom to the top of the windings caused by natural convection air flow through the cooling ducts. A constant ratio of hottest spot winding temperature rise to average winding temperature rise should be used in product standards for all insulation temperature classes. A ratio of 1.5 is suggested for ventilated dry type transformers above 500 kVA. This would increase the hottest spot temperature allowance from 30 C to 60 C and decrease the permissible average winding temperature rise from 150 C to 120 C for the 220 C insulation temperature class.

Small Spot, Brighter Beam  

NLE Websites -- All DOE Office Websites (Extended Search)

Small Spot, Brighter Beam Small Spot, Brighter Beam Small Spot, Brighter Beam Print Do you notice the brighter beam? During the most recent shutdown, all of the corrector magnets were replaced with sextupoles, reducing the horizontal emittance and increasing beam brightness. "This is part of ongoing improvement to keep the ALS on the cutting edge," says Alastair MacDowell, a beamline scientist on Beamline 12.2.2. The brightness has increased by a factor of about three in the storage ring. Beamlines on superbend or center-bend magnets will see the most noticeable increase in brightness, but the horizontal beam size and divergence have been substantially reduced at all beamlines. "We are starting to approach the resolution of many beamlines. Therefore, not every beamline will be able to resolve the full improvement," says Christoph Steier, project leader of the brightness upgrade. Though superbend and center-bend magnet source sizes are reduced by roughly a factor of three, "measured improvements so far range from a factor of 2-2.5," Steier says. He and MacDowell agree that the beamline optics are likely the limiting factor in resolving the full improvement at the beamlines.

Unimodular Gravity and Averaging  

E-Print Network (OSTI)

The question of the averaging of inhomogeneous spacetimes in cosmology is important for the correct interpretation of cosmological data. In this paper we suggest a conceptually simpler approach to averaging in cosmology based on the averaging of scalars within unimodular gravity. As an illustration, we consider the example of an exact spherically symmetric dust model, and show that within this approach averaging introduces correlations (corrections) to the effective dynamical evolution equation in the form of a spatial curvature term.

Characterization of Ti diffusion in PVD deposited WTi/AlCu metallization on monocrystalline Si by means of secondary ion mass spectroscopy  

Science Journals Connector (OSTI)

The diffusion behavior of Titanium in Al0.5Cu/W18Ti (at.%) metallization stacks on monocrystalline Silicon has been investigated. The metallization system was prepared by in situ sputtering deposition. It is demonstrated that \\{WTi\\} is not stable as a diffusion barrier between Al0.5Cu and Si in temperature ranges between 623 K and 673 K due to Ti depletion. The Ti diffusion in Al0.5Cu is characterized by diffusion profiles prepared by secondary ion mass spectroscopy after annealing. The activation energy derived from this data is 2.28 eV for Ti diffusion into Al0.5Cu. The causal chain of detecting this behavior is described application-oriented.

Predicting hottest spot temperatures in ventilated dry type transformer windings  

SciTech Connect

Test data indicates that hottest spot allowances used in IEEE standards for ventilated dry type transformers above 500 kVA are too low. A mathematical model to predict hottest spot temperature rises in ventilated dry type transformers was developed. Data from six layer type test windings and a 2500 kva prototype was used to refine the model. A correlation for the local heat transfer coefficient in the cooling ducts was developed. The model was used to study the effect of various parameters on the ratio of hottest spot to average winding temperature rise. The number of conductor layers, insulation thickness, and conductor strand size were found to have only a minor effect on the ratio. Winding height was found to be the main parameter influencing the ratio of hottest spot to average winding temperature rise. The study based on the mathematical model confirmed previous conclusions based on test data that the hottest spot allowances used in IEEE standards for ventilated dry type transformers above 500 kVA should be revised.

Natural Gas Prices: Well Above Recent Averages  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: The recent surge in spot prices at the Henry Hub are well above a typical range for 1998-1999 (in this context, defined as the average, +/- 2 standard deviations). Past price surges have been of short duration. The possibility of a downward price adjustment before the end of next winter is a source of considerable risk for storage operators who acquire gas at recent elevated prices. Storage levels in the Lower 48 States were 7.5 percent below the 5-year average (1995-1999) by mid-August (August 11), although the differential is only 6.4 percent in the East, which depends most heavily on storage to meet peak demand. Low storage levels are attributable, at least in part, to poor price incentives: high current prices combined with only small price

Americans' Average Radiation Exposure  

SciTech Connect

We live with radiation every day. We receive radiation exposures from cosmic rays, from outer space, from radon gas, and from other naturally radioactive elements in the earth. This is called natural background radiation. It includes the radiation we get from plants, animals, and from our own bodies. We also are exposed to man-made sources of radiation, including medical and dental treatments, television sets and emission from coal-fired power plants. Generally, radiation exposures from man-made sources are only a fraction of those received from natural sources. One exception is high exposures used by doctors to treat cancer patients. Each year in the United States, the average dose to people from natural and man-made radiation sources is about 360 millirem. A millirem is an extremely tiny amount of energy absorbed by tissues in the body.

Gasoline and Diesel Fuel Update (EIA)

9 9 1 July 2009 Short-Term Energy Outlook July 7, 2009 Release Highlights After climbing for much of the year, the spot price of West Texas Intermediate (WTI) crude oil hovered around $70 per barrel through most of June. The price of WTI crude oil is expected to average near $70 per barrel through the second half of 2009, an increase of about $18 compared with the average for the first half of the year. The WTI spot price is projected to rise slowly as economic conditions improve, and to average about $72 per barrel in 2010. U.S average prices for regular-grade gasoline, which reached $2.69 per gallon in EIA's June 22 weekly survey, have fallen back slightly. Gasoline prices are

Spot Distillate & Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: Retail distillate prices follow the spot distillate markets, and crude oil prices have been the main driver behind distillate spot price increases until recently. Crude oil rose about 36 cents per gallon from its low point in mid February 1999 to the middle of January 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, heating oil spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled slightly higher as the New York Harbor market began to

Canopy hot-spot as crop identifier  

SciTech Connect

Illuminating any reflective rough or structured surface by a directional light source results in an angular reflectance distribution that shows a narrow peak in the direction of retro-reflection. This is called the Heiligenschein or hot-spot of vegetation canopies and is caused by mutual shading of leaves. The angular intensity distribution of the hot-spot, its brightness and slope, are therefore indicators of the plant's geometry. We propose the use of hot-spot characteristics as crop identifiers in satellite remote sensing because the canopy hot-spot carries information about plant stand architecture that is more distinctive for different plant species than, for instance, their spectral reflectance characteristics. A simple three-dimensional Monte Carlo/ray tracing model and an analytic two-dimensional model are developed to estimate the angular distribution of the hot-spot as a function of the size of the plant leaves. The results show that the brightness-distribution and slope of the hot-spot change distinctively for different leaf sizes indicating a much more peaked maximum for the smaller leaves.

Doppler-free Yb spectroscopy with the fluorescence spot technique  

SciTech Connect

We demonstrate a simple technique to measure the resonant frequency of the 398.9-nm {sup 1}S{sub 0}{leftrightarrow}{sup 1}P{sub 1} transition for the different Yb isotopes. The technique, which works by observing and aligning fluorescence spots, has enabled us to measure transition frequencies and isotope shifts with an accuracy of 60 MHz. We provide wavelength measurements for the transition that differ from previously published work. Our technique also allows for the determination of Doppler-shifted transition frequencies for photoionization experiments when the atomic beam and the laser beam are not perpendicular and furthermore allows us to determine the average velocity of the atoms along the direction of the atomic beam.

Dealing in practice with hot-spots  

E-Print Network (OSTI)

The hot-spot phenomenon is a relatively frequent problem occurring in current photovoltaic generators. It entails both a risk for the photovoltaic module's lifetime and a decrease in its operational efficiency. Nevertheless, there is still a lack of widely accepted procedures for dealing with them in practice. This paper presents the IES-UPM observations on 200 affected modules. Visual and infrared inspection, electroluminescence, peak power and operating voltage tests have been accomplished. Hot-spot observation procedures and well defined acceptance and rejection criteria are proposed, addressing both the lifetime and the operational efficiency of the modules. The operating voltage has come out as the best parameter to control effective efficiency losses for the affected modules. This procedure is oriented to its possible application in contractual frameworks.

The fractal nature of vacuum arc cathode spots  

SciTech Connect

Cathode spot phenomena show many features of fractals, for example self-similar patterns in the emitted light and arc erosion traces. Although there have been hints on the fractal nature of cathode spots in the literature, the fractal approach to spot interpretation is underutilized. In this work, a brief review of spot properties is given, touching the differences between spot type 1 (on cathodes surfaces with dielectric layers) and spot type 2 (on metallic, clean surfaces) as well as the known spot fragment or cell structure. The basic properties of self-similarity, power laws, random colored noise, and fractals are introduced. Several points of evidence for the fractal nature of spots are provided. Specifically power laws are identified as signature of fractal properties, such as spectral power of noisy arc parameters (ion current, arc voltage, etc) obtained by fast Fourier transform. It is shown that fractal properties can be observed down to the cutoff by measurement resolution or occurrence of elementary steps in physical processes. Random walk models of cathode spot motion are well established: they go asymptotically to Brownian motion for infinitesimal step width. The power spectrum of the arc voltage noise falls as 1/f {sup 2}, where f is frequency, supporting a fractal spot model associated with Brownian motion.

Regional averaging and scaling in relativistic cosmology  

E-Print Network (OSTI)

Averaged inhomogeneous cosmologies lie at the forefront of interest, since cosmological parameters like the rate of expansion or the mass density are to be considered as volume-averaged quantities and only these can be compared with observations. For this reason the relevant parameters are intrinsically scale-dependent and one wishes to control this dependence without restricting the cosmological model by unphysical assumptions. In the latter respect we contrast our way to approach the averaging problem in relativistic cosmology with shortcomings of averaged Newtonian models. Explicitly, we investigate the scale-dependence of Eulerian volume averages of scalar functions on Riemannian three-manifolds. We propose a complementary view of a Lagrangian smoothing of (tensorial) variables as opposed to their Eulerian averaging on spatial domains. This program is realized with the help of a global Ricci deformation flow for the metric. We explain rigorously the origin of the Ricci flow which, on heuristic grounds, has already been suggested as a possible candidate for smoothing the initial data set for cosmological spacetimes. The smoothing of geometry implies a renormalization of averaged spatial variables. We discuss the results in terms of effective cosmological parameters that would be assigned to the smoothed cosmological spacetime.

Dark spot formation relative to ITO surface roughness for polyfluorene Dark spot formation relative to ITO surface roughness for polyfluorene devices Title Dark spot formation relative to ITO surface roughness for polyfluorene devices Publication Type Journal Article Year of Publication 2004 Authors Liu, Gao, John B. Kerr, and Stephen G. Johnson Journal Synthetic Metals Volume 144 Pagination 1-6 Keywords dark spot, failure mechanism, interface, ito surface, oled Abstract The failure behaviors of ITO/PEDOT;PSS/polyfluorene/Al devices are different depending on the surface roughness of the sputtered ITO anode film. The spikes on ITO surface are responsible for the initial local shorts of the device, which develop into dark spots very quickly. Indium adsorption is observed on the polymer and Al cathode interface. A chemical etching procedure is used to smoothen the ITO surface without changing the ITO thickness and the sheet resistance. Devices made out of smooth ITO show minimum changes at polymer-cathode interface during operation.

The formation of a single-pulse electrospark deposition spot  

Science Journals Connector (OSTI)

The investigation of the formation mechanism of the rotating-type electrospark deposition (ESD) was presented, based on studying the single-pulse electrospark deposition spot. Four different substrate/electrode couples were selected to produce single-pulse deposition spots. The similar morphology of the spots and element migration tendency were detected. A heuristic physical model was established to interpret this deposition process. The concept of “gush and splash effect” was originally proposed and proved as the dominant factor in the formation mechanism of the single-pulse electrospark deposition spot. In addition, the rotation behavior of the electrode was identified to impact on the formation of the single-pulse deposition spot.

Challenges will be presented in the context of assessing the required level of extrapolation beyond the performance of today's CEBAF polarized source operating at ~ 200 uA average current. Estimates of performance at higher current will be based on hours-long demonstrations at 1 and 4 mA. Particular attention will be paid to beam-related lifetime-limiting mechanisms, and strategies to construct a photogun that operate reliably at bias voltage > 350kV.

Wall and laser spot motion in cylindrical hohlraums  

SciTech Connect

Wall and laser spot motion measurements in empty, propane-filled and plastic (CH)-lined gold coated cylindrical hohlraums were performed on the Omega laser facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)]. Wall motion was measured using axial two-dimensional (2D) x-ray imaging and laser spot motion was perpendicularly observed through a thinned wall using streaked hard x-ray imaging. Experimental results and 2D hydrodynamic simulations show that while empty targets exhibit on-axis plasma collision, CH-lined and propane-filled targets inhibit wall expansion, corroborated with perpendicular streaked imaging showing a slower motion of laser spots.

Gasoline and Diesel Fuel Update (EIA)

2 2 1 Short-Term Energy Outlook August 2002 Overview World Oil Markets: Oil prices remained relatively high in July, averaging close to the expectations reported in the July Outlook. The average spot West Texas Intermediate (WTI) price in July was approximately $27 per barrel. As always, a wide range of possibilities exists for oil price movements over the next year and a half. However, given the amount of growth in world demand expected through 2003, we think that likely scenarios for OPEC and non-OPEC output growth imply continued tightening of markets (lower commercial inventories) and continued support for crude oil prices near or slightly above current levels through mid-2003. The average WTI spot price is expected to edge upward t

HIGH AVERAGE POWER OPTICAL FEL AMPLIFIERS.  

SciTech Connect

Historically, the first demonstration of the optical FEL was in an amplifier configuration at Stanford University [l]. There were other notable instances of amplifying a seed laser, such as the LLNL PALADIN amplifier [2] and the BNL ATF High-Gain Harmonic Generation FEL [3]. However, for the most part FELs are operated as oscillators or self amplified spontaneous emission devices. Yet, in wavelength regimes where a conventional laser seed can be used, the FEL can be used as an amplifier. One promising application is for very high average power generation, for instance FEL's with average power of 100 kW or more. The high electron beam power, high brightness and high efficiency that can be achieved with photoinjectors and superconducting Energy Recovery Linacs (ERL) combine well with the high-gain FEL amplifier to produce unprecedented average power FELs. This combination has a number of advantages. In particular, we show that for a given FEL power, an FEL amplifier can introduce lower energy spread in the beam as compared to a traditional oscillator. This properly gives the ERL based FEL amplifier a great wall-plug to optical power efficiency advantage. The optics for an amplifier is simple and compact. In addition to the general features of the high average power FEL amplifier, we will look at a 100 kW class FEL amplifier is being designed to operate on the 0.5 ampere Energy Recovery Linac which is under construction at Brookhaven National Laboratory's Collider-Accelerator Department.

The historically close relationships between the major benchmarks made WTI prices a reliable indicator of the average cost of crude oil to U.S. refiners, referred to as the refiner acquisition cost (RAC) of crude oil. As crude oil is the primary feedstock and cost component of refined petroleum products, RAC prices had been used to

Indirect CP violation results and HFAG averages  

E-Print Network (OSTI)

The current status of the search for indirect CP violation in the neutral D meson system at the B-factories and at LHCb is reported. The indirect CP asymmetry search is performed by the measurement of the proper-time asymmetry ($A_{\\Gamma}$) in decays of $D^0-\\bar{D^0}$ mesons to CP eigenstates, $K^-K^+$ and $\\pi^- \\pi^+$, and by $y_{CP}$, the ratio between the effective lifetime measured in decay to a CP eigenstate and that to the mixed eigenstate $K \\pi$. All results are consistent with the no CP violation hypothesis. The latest world averages for mixing and CP asymmetry in the charm sector evaluated by the Heavy Flavour Averaging Group are presented. The no mixing hypothesis is excluded at more than 12 standard deviations. The search for direct and indirect CP violation in the charm sector is consistent with no CP violation at 2.0% confident level.

Analysis of testing the single-fluxon dynamics in a long Josephson junction by a dissipative spot  

SciTech Connect

A change of the [ital I]-[ital V] characteristics of a long Josephson junction, operating in the zero-field single-fluxon regime, under the action of a hot spot'' (e.g., created by a focused electron beam) is calculated analytically by means of the perturbation theory, and also investigated numerically. The change of the average voltage at a given value of the bias current is calculated as a function of the hot spot-position. The overlap Josephson junction geometry is considered in detail, while the inline one is briefly discussed. A good accord between analytical and numerical results is found. The results are relevant for the interpretation of the low-temperature scanning electron microscopy experiments on imaging the fluxon dynamic states in a long Josephson junction.

Science Journals Connector (OSTI)

An average resonance capture study of Te124 was carried out by bombarding samples of Te123 with 2- and 24-keV neutron beams. The complete set of 0+, 1+, 2+ states disclosed by the experiment is consistent with the data of Robinson, Hamilton, and Snelling, demonstrating that there are no undetected states of these spins (especially 0+ states) below about 2500 keV. In particular, proposed 0+ levels at 1156 and 1290 keV are ruled out. This impacts various attempted interpretations in terms of intruder states, U(5), and O(6) symmetries.

Average deployments versus missile and defender parameters  

SciTech Connect

This report evaluates the average number of reentry vehicles (RVs) that could be deployed successfully as a function of missile burn time, RV deployment times, and the number of space-based interceptors (SBIs) in defensive constellations. Leakage estimates of boost-phase kinetic-energy defenses as functions of launch parameters and defensive constellation size agree with integral predictions of near-exact calculations for constellation sizing. The calculations discussed here test more detailed aspects of the interaction. They indicate that SBIs can efficiently remove about 50% of the RVs from a heavy missile attack. The next 30% can removed with two-fold less effectiveness. The next 10% could double constellation sizes. 5 refs., 7 figs.

The Romanian Energy System Structure and its Impact on the Electricity Spot Market  

Science Journals Connector (OSTI)

Abstract The international economic literature offers a significant number of publications approaching the European energy markets functioning, including comparative studies. The development and performances of the Romanian electricity spot market were less investigated, mainly because of the relatively short period of its functioning. The paper quantifies the impact of the electricity generation utilities’ structure by primary energy resources, on bidding prices resulted after the closure of the day ahead market. The multidimensional regression method was utilized for the models development. As a result, three distinct econometric models were obtained for different hourly periods of the day (off peak hours, peak hours, daily average) for working days and other three models for the weekend days. Based on these models, negative and positive correlations were established between the electricity prices and the seasonal contribution of the different categories of energy facilities to the demand curve coverage.

Io's active hot spots, which are presently mapped on the basis of IR photometry of this moon's occultation by other Gallilean satellites, are obtained with greatest spatial resolution near the sub-earth point. A model is developed for the occultation lightcurves, and its fitting to the data defines the apparent path of the occulting satellite relative to Io; the mean error in apparent relative position of occulting satellites is of the order of 178 km. A heretofore unknown, 20-km diameter hot spot is noted on Io's leading hemisphere. 31 references.

2 2006 (next release 2:00 p.m. on January 19, 2006) 2 2006 (next release 2:00 p.m. on January 19, 2006) Warmer-than-normal temperatures throughout the country led to lower natural gas spot prices at many trading locations in the Lower 48 States, while some markets exhibited modest increases since last Wednesday. For the week (Wednesday-Wednesday, January 4-11), the price for next-day delivery at the Henry Hub decreased 70 cents per MMBtu, or 7.6 percent to $8.55 per MMBtu. The NYMEX futures contract for February delivery at the Henry Hub settled yesterday (January 11) at $9.238 per MMBtu, which was 96 cents less than last Wednesday's price. Natural gas in storage decreased to 2,621 Bcf as of January 6, leaving the inventories at 11.8 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil moved up $0.50 per barrel or about 1 percent since last Wednesday to $63.91 per barrel or $11.02 per MMBtu. As natural gas prices have declined while crude oil prices remain above $60 per barrel, the relative position of these prices has returned to a more typical pattern, where the price of natural gas is below that of crude oil on a Btu basis. The Henry Hub spot price was 24 percent below the WTI crude oil price from the beginning of 2005 up to the point that Hurricane Katrina made landfall in late August. For the remainder of 2005, the Henry Hub spot price exceeded the WTI price by 15 percent. However, that unusual pattern of relative prices was changing by the end of 2005, and the Henry Hub spot price has been 17 percent below the WTI price on average so far in January.

Bipolar magnetic spots from dynamos in stratified spherical shell turbulence  

E-Print Network (OSTI)

Recent work by Mitra et al. (2014) has shown that in strongly stratified forced two-layer turbulence with helicity and corresponding large-scale dynamo action in the lower layer, a magnetic field occurs in the upper layer in the form of sharply bounded bipolar magnetic spots. Here we extend this model to spherical wedge geometry covering the northern hemisphere up to 75{\\deg} latitude and an azimuthal extent of 180{\\deg}. The kinetic helicity and therefore also the large-scale magnetic field are strongest at low latitudes. For moderately strong stratification, several bipolar spots form that fill eventually the full longitudinal extent. At early times, the polarity of spots reflects the orientation of the underlying azimuthal field, as expected from {\\Omega}-shaped flux loops. At late times their tilt changes such that there is a radial field of opposite orientation at different latitudes separated by about 10{\\deg}. Our model demonstrates for the first time the spontaneous formation of spots of sizes much la...

Spot welding of steel and aluminum using insert sheet  

SciTech Connect

Automobile industries have been increasingly interested in the use of aluminum and thus joining of steel and aluminum becomes of importance. The joining of the two types of metal raises a problem of brittle welds caused by the formation of intermetallic compounds. The authors solved the problem by using an insert sheet. This paper deals with the resistance spot welding of steel and aluminum sheets using insert sheets. The insert sheet used in the present development was a steel/aluminum clad sheet of the 0.8 mm thickness with 50% steel and 50% aluminum. The clad sheet was produced by warm rolling of steel and aluminum with a direct resistance heating process. Steel to be warm rolled was of EDDQ of the 0.4 mm thickness and aluminum was of JIS A1050 of 0.6 mm thickness. The mechanical properties of the insert clad sheets were in between those of the steel sheets and the aluminum sheets, while the clad sheets showed much better formability than the aluminum sheets. Resistance spot welding was conducted for 0.8 mm thick EDDQ steel sheets and 1.0 mm thick aluminum alloy (AL-5.5%Mg) sheets under the welding force of 1.96 kN, welding current ranging between 4.2 and 20.1 kA, and welding time from 0.5 to 10 cycles. The steel was spot welded to the steel side of the insert sheet while the aluminum was welded to the aluminum side. What the authors investigated were the applicable welding current range, nugget diameter, tensile shear strength, U-tension strength, and macro- and microstructures. In conclusion, steel sheets can be spot welded to aluminum sheets without difficulty by using clad sheets as insert materials while the strength level of the dissimilar metal spot welds is close to that of aluminum joints.

Gasoline and Diesel Fuel Update (EIA)

September 2002 September 2002 1 Short-Term Energy Outlook September 2002 Overview World Oil Markets: The waxing and waning intensities of concern surrounding potential military action against Iraq and uncertainty over OPEC production policy leading up to their September 19 meeting have contributed to WTI spot crude oil prices bouncing between $26 and $30 per barrel since early August. The average spot WTI price in August was $28.40 per barrel. Developments suggesting an easing of tensions could temporarily send prices lower in the short run. However, a modest measure of restraint with respect to oil output by OPEC would probably keep oil prices closer to $30 per barrel than to $20 through 2003, even if the political and military status quo were maintained. Solid growth in world oil demand this winter (and for 2003 as a whole) is

Forecasting Forecasting Crude Oil Spot Price Using OECD Petroleum Inventory Levels MICHAEL YE, ∗ JOHN ZYREN, ∗∗ AND JOANNE SHORE ∗∗ Abstract This paper presents a short-term monthly forecasting model of West Texas Intermedi- ate crude oil spot price using OECD petroleum inventory levels. Theoretically, petroleum inventory levels are a measure of the balance, or imbalance, between petroleum production and demand, and thus provide a good market barometer of crude oil price change. Based on an understanding of petroleum market fundamentals and observed market behavior during the post-Gulf War period, the model was developed with the objectives of being both simple and practical, with required data readily available. As a result, the model is useful to industry and government decision-makers in forecasting price and investigat- ing the impacts of changes on price, should inventories,

Research on patterns in the fluctuation of the co-movement between crude oil futures and spot prices: A complex network approach  

Science Journals Connector (OSTI)

Abstract The price of crude oil is fluctuating. Researchers focus on the fluctuation of crude oil prices or relationship between crude oil futures and spot prices. However, the relationship also presents fluctuation which draws our attention. This paper designed a complex network approach for examining the dynamics of the co-movement between crude oil futures and spot prices. We defined the co-movement modes by a coarse-graining procedure and analyzed the transformation characteristics between the modes by weighted complex network models and evolutionary models. We analyzed the parameters of these models by using the West Texas Intermediate crude oil future prices and the Daqing (China) crude oil spot prices from November 25, 2002 to March 22, 2011 as sample data. The results indicate that the co-movement modes of the crude oil futures and spot prices are clustered around a few critical modes during the evolution. The co-movement of the crude oil prices has the characteristic of grouping, and the conversion of the co-movement modes requires an average of 5–7 days. There are some important transitional phases in the evolution of prices, and the results validate the current trend of rising oil prices. This research may provide information for the oil price decision-making process, and more importantly, provides a new approach for examining the co-movement between variables.

Evidence of randomness in United States spot oil prices  

SciTech Connect

This study investigates U.S. crude oil spot-market prices to determine if they were cyclical, autoregressive, or random in nature. The fact that oil-price volatility emerged only with the rise of spot markets meant that data for this type of an analysis were not previously available. The hypothesis tested was that U.S. crude oil price changes are neither cyclical nor autocorrelated, and are, therefore, random. Daily data on U.S. crude oil spot market prices (for the period of December 3, 1984 to November 4, 1988) were analyzed using spectral analysis; this converts time-series data into a frequency series, where it can be analyzed using more-powerful statistical methods. The spectral results of the price series gave a maximum power spectrum of 0.026, which is considerably smaller than the significance level of 0.052, considered acceptable using a 99% confidence level. The conclusion reached was that there was no significant cyclicality or autocorrelation in the data. This indicated that the U.S. crude oil prices are efficient, and that it would not be possible to predict crude oil price changes by using historical price data, seasonality, or business cycles.

Understanding plastic deformation in thermal glasses from single-soft-spot dynamics  

E-Print Network (OSTI)

By considering the low-frequency vibrational modes of amorphous solids, Manning and Liu [Phys. Rev. Lett. 107, 108302 (2011)] showed that a population of "soft spots" can be identified that are intimately related to plasticity at zero temperature under quasistatic shear. In this work we track individual soft spots with time in a two-dimensional sheared thermal Lennard Jones glass at temperatures ranging from deep in the glassy regime to above the glass transition temperature. We show that the lifetimes of individual soft spots are correlated with the timescale for structural relaxation. We additionally calculate the number of rearrangements required to destroy soft spots, and show that most soft spots can survive many rearrangements. Finally, we show that soft spots are robust predictors of rearrangements at temperatures well into the super-cooled regime. Altogether, these results pave the way for mesoscopic theories of plasticity of amorphous solids based on dynamical behavior of individual soft spots.

More specifically, while the West Texas Intermediate (WTI) crude oil spot price averaged $28.84 in October, about $6.70 per barrel above the year-ago level (Figure 1), the WTI average price for fourth quarter 2002 is now projected to soften to $28.20, which is about $2 per barrel below our fourth-quarter projection from last month. Meanwhile, OECD inventory levels, which are now approaching 5 -year lows, should begin to rise over the next few months as additional supplies reach markets, and return to the middle of their observed range by spring.

Single-shot and single-spot measurement of laser ablation threshold for carbon nanotubes  

E-Print Network (OSTI)

A simple and convenient procedure for single-shot, single-spot ablation threshold measurement has been developed. It is based on the employment of cylindrical lens to obtain elliptical Gaussian laser spot. The ablated spot chords which are parallel to the minor axis were measured across the spot major axis which is proportional to the fluence cross-section thus providing wide range dependence of damaged spot size versus fluence in one spot measurement. For both conventional and new-developed procedures the ablation threshold for typical Nd:YAG laser parameters (1064 nm, 10 ns) has been measured as 50 mJ/cm2 which is one order of magnitude lower than that for a bulk graphite.

Transformation from spots to waves in a model of actin pattern formation  

E-Print Network (OSTI)

Actin networks in certain single-celled organisms exhibit a complex pattern-forming dynamics that starts with the appearance of static spots of actin on the cell cortex. Spots soon become mobile, executing persistent random walks, and eventually give rise to traveling waves of actin. Here we describe a possible physical mechanism for this distinctive set of dynamic transformations, by equipping an excitable reaction-diffusion model with a field describing the spatial orientation of its chief constituent (which we consider to be actin). The interplay of anisotropic actin growth and spatial inhibition drives a transformation at fixed parameter values from static spots to moving spots to waves.

How this variability may alter the direct aerosol radiative forcing (DARF), however, is largely unknown. To quantify changes in the time-averaged DARF, we perform an assessment of 29 days of high temporal resolution ground-based data collected during the Two-Column Aerosol Project (TCAP) on Cape Cod, which is downwind of metropolitan areas. We demonstrate that strong diurnal changes of aerosol loading (about 20% on average) have a negligible impact on the 24-h average DARF, when daily averaged optical properties are used to find this quantity. However, when there is a sparse temporal sampling of aerosol properties, which may preclude the calculation of daily averaged optical properties, large errors (up to 100%) in the computed DARF may occur. We describe a simple way of reducing these errors, which suggests the minimal temporal sampling needed to accurately find the forcing.

Averaged dynamics of ultra-relativisitc charged particles beams  

E-Print Network (OSTI)

In this thesis, we consider the suitability of using the charged cold fluid model in the description of ultra-relativistic beams. The method that we have used is the following. Firstly, the necessary notions of kinetic theory and differential geometry of second order differential equations are explained. Then an averaging procedure is applied to a connection associated with the Lorentz force equation. The result of this averaging is an affine connection on the space-time manifold. The corresponding geodesic equation defines the averaged Lorentz force equation. We prove that for ultra-relativistic beams described by narrow distribution functions, the solutions of both equations are similar. This fact justifies the replacement of the Lorentz force equation by the simpler {\\it averaged Lorentz force equation}. After this, for each of these models we associate the corresponding kinetic model, which are based on the Vlasov equation and {\\it averaged Vlasov equation} respectively. The averaged Vlasov equation is simpler than the original Vlasov equation. This fact allows us to prove that the differential operation defining the averaged charged cold fluid equation is controlled by the {\\it diameter of the distribution function}, by powers of the {\\it energy of the beam} and by the time of evolution $t$. We show that the Vlasov equation and the averaged Vlasov equation have similar solutions, when the initial conditions are the same. Finally, as an application of the {\\it averaged Lorentz force equation} we re-derive the beam dynamics formalism used in accelerator physics from the Jacobi equation of the averaged Lorentz force equation.

August 29, 2002 (next release 2:00 p.m. on September 5) August 29, 2002 (next release 2:00 p.m. on September 5) Despite sizeable drops in both spot and futures contract prices in the past two days, week-on-week (Wednesday, August 21 to Wednesday August 28) increases were recorded in both cash and futures markets. Temperatures which had begun to moderate even before Thursday, August 22, particularly in the Northeast and West regions, seemed finally to begin exerting downward pressure on prices. For the week, the spot price at the Henry Hub gained $0.11 per MMBtu to average $3.33 yesterday (Wednesday, August 28). The NYMEX futures contract for September delivery expired yesterday at the closing price of $3.288 per MMBtu, up only $0.014 from the previous Wednesday's settlement. The Energy Information Administration's (EIA) Weekly Natural Gas Storage Report showed total stocks of 2,716 Bcf for the week ended Friday, August 23, which is 13 percent above the 5-year average. The run-up in the spot price of West Texas Intermediate (WTI) crude oil that resulted in an increase of $2.18 per barrel over the previous week was almost completely offset this past week, as the WTI spot price fell $2.06 per barrel to end trading on Wednesday, August 28 at an average price of $28.31 per barrel, or $4.88 per MMBtu.

Measurement of average resistance in underwater breathing apparatus  

SciTech Connect

Underwater Breathing Apparatus (UBA) have long been characterized by the mechanical work done on them during simulated breathing. For 20 years, the work of breathing has been divided by tidal volume to yield what is properly considered a volume-averaged pressure. The authors assert that when volume-averaged pressure is divided by a factor proportional to ventilation, the result is a measure of flow resistance averaged over an entire breath. This point is illustrated with both theoretical and actual pressure-volume and pressure-flow curves for a MK 16 closed-circuit UBA.

Time average vibration fringe analysis using Hilbert transformation  

SciTech Connect

Quantitative phase information from a single interferogram can be obtained using the Hilbert transform (HT). We have applied the HT method for quantitative evaluation of Bessel fringes obtained in time average TV holography. The method requires only one fringe pattern for the extraction of vibration amplitude and reduces the complexity in quantifying the data experienced in the time average reference bias modulation method, which uses multiple fringe frames. The technique is demonstrated for the measurement of out-of-plane vibration amplitude on a small scale specimen using a time average microscopic TV holography system.

Averaging Spacetime: Where do we go from here?  

E-Print Network (OSTI)

The construction of an averaged theory of gravity based on Einstein's General Relativity is very difficult due to the non-linear nature of the gravitational field equations. This problem is further exacerbated by the difficulty in defining a mathematically precise covariant averaging procedure for tensor fields over differentiable manifolds. Together, these two ideas have been called the averaging problem for General Relativity. In the first part of the talk, an attempt to review some the various approaches to this problem will be given, highlighting strengths, weaknesses, and commonalities between them. In the second part of the talk, an argument will be made, that if one wishes to develop a well-defined averaging procedure, one may choose to parallel transport along geodesics with respect to the Levi-Cevita connection or, use the Weitzenb\\"ock connection and ensure the transportation is independent of path. The talk concludes with some open questions to generate further discussion.

Direct and indirect effects of southern flounder predation on a spot population: Experimental and model analyses  

SciTech Connect

We have previously shown that southern flounder (Paralichthys lethostigma Jordan and Gilbert) influence the survival and size-distribution of spot (Leiostomus xanthurus Lafayette) and other small estuarine fishes in experimental ponds. In this paper, we seek to determine whether these of effects can be accounted for by direct size-dependent predation or if there is also evidence for indirect behavioral effects on spot foraging which might alter their survival or population size structure. In our experiment, spot were allowed to grow in the presence and absence of southern flounder in an experimental estuarine pond for 101 days. Each treatment was replicated three times. We also apply a recently published simulation model of the flounder-spot interaction to this experiment to independently test the model and to estimate the direct effects of flounder predation on spot survival and size structure.

Time-average TV holography for vibration fringe analysis  

SciTech Connect

Time-average TV holography is widely used method for vibration measurement. The method generates speckle correlation time-averaged J0 fringes that can be used for full-field qualitative visualization of mode shapes at resonant frequencies of an object under harmonic excitation. In order to map the amplitudes of vibration, quantitative evaluation of the time-averaged fringe pattern is desired. A quantitative evaluation procedure based on the phase-shifting technique used in two beam interferometry has also been adopted for this application with some modification. The existing procedure requires a large number of frames to be recorded for implementation. We propose a procedure that will reduce the number of frames required for the analysis. The TV holographic system used and the experimental results obtained with it on an edge-clamped, sinusoidally excited square aluminium plate sample are discussed.

High average power scaleable thin-disk laser  

DOE Patents (OSTI)

Using a thin disk laser gain element with an undoped cap layer enables the scaling of lasers to extremely high average output power values. Ordinarily, the power scaling of such thin disk lasers is limited by the deleterious effects of amplified spontaneous emission. By using an undoped cap layer diffusion bonded to the thin disk, the onset of amplified spontaneous emission does not occur as readily as if no cap layer is used, and much larger transverse thin disks can be effectively used as laser gain elements. This invention can be used as a high average power laser for material processing applications as well as for weapon and air defense applications.

Averaged equations for Josephson junction series arrays with LRC load  

E-Print Network (OSTI)

We derive the averaged equations describing a series array of Josephson junctions shunted by a parallel inductor-resistor-capacitor load. We assume that the junctions have negligable capacitance ($\\beta = 0$), and derive averaged equations which turn out to be completely tractable: in particular the stability of both in-phase and splay states depends on a single parameter, $\\del$. We find an explicit expression for $\\delta$ in terms of the load parameters and the bias current. We recover (and refine) a common claim found in the technical literature, that the in-phase state is stable for inductive loads and unstable for capacitive loads.

An investigation of nonlinear xenon oscillation by method of averaging  

Science Journals Connector (OSTI)

A nonlinear analysis of xenon-temperature controlled nuclear reactor dynamics is presented. The set of equations in question belongs to a general class of rate equations with quadratic nonlinearities. Boundedness of the solutions is examined. The mean value of periodic solutions for the flux is shown to be always less than the equilibrium value. The Bogoliubov's method of averaging as extended by Case is applied to obtain approximate solutions. The mechanism of the existence of relaxation oscillations in the linear stability region is analyzed. Computer calculations are performed and found in good agreement with the approximate solutions obtained by means of the method of averaging.

Disk-averaged Spectra & light-curves of Earth  

E-Print Network (OSTI)

We are using computer models to explore the observational sensitivity to changes in atmospheric and surface properties, and the detectability of biosignatures, in the globally averaged spectra and light-curves of the Earth. Using AIRS (Atmospheric Infrared Sounder) data, as input for atmospheric and surface properties, we have generated spatially resolved high-resolution synthetic spectra using the SMART radiative transfer model, for a variety of conditions, from the UV to the far-IR (beyond the range of current Earth-based satellite data). We have then averaged over the visible disk for a number of different viewing geometries to quantify the sensitivity to surface types and atmospheric features as a function of viewing geometry, and spatial and spectral resolution. These results have been processed with an instrument simulator to improve our understanding of the detectable characteristics of Earth-like planets as viewed by the first generation extrasolar terrestrial planet detection and characterization missions (Terrestrial Planet Finder/Darwin and Life finder). The wavelength range of our results are modelled over are applicable to both the proposed visible coronograph and mid-infrared interferometer TPF architectures. We have validated this model against disk-averaged observations by the Mars Global Surveyor Thermal Emission Spectrometer (MGS TES). This model was also used to analyze Earth-shine data for detectability of planetary characteristics and biosignatures in disk-averaged spectra.

Photovoltaic ground fault and blind spot electrical simulations.  

SciTech Connect

Ground faults in photovoltaic (PV) systems pose a fire and shock hazard. To mitigate these risks, AC-isolated, DC grounded PV systems in the United States use Ground Fault Protection Devices (GFPDs), e.g., fuses, to de-energize the PV system when there is a ground fault. Recently the effectiveness of these protection devices has come under question because multiple fires have started when ground faults went undetected. In order to understand the limitations of fuse-based ground fault protection in PV systems, analytical and numerical simulations of different ground faults were performed. The numerical simulations were conducted with Simulation Program with Integrated Circuit Emphasis (SPICE) using a circuit model of the PV system which included the modules, wiring, switchgear, grounded or ungrounded components, and the inverter. The derivation of the SPICE model and the results of parametric fault current studies are provided with varying array topologies, fuse sizes, and fault impedances. Closed-form analytical approximations for GFPD currents from faults to the grounded current carrying conductor-known as %E2%80%9Cblind spot%E2%80%9D ground faults-are derived to provide greater understanding of the influence of array impedances on fault currents. The behavior of the array during various ground faults is studied for a range of ground fault fuse sizes to determine if reducing the size of the fuse improves ground fault detection sensitivity. The results of the simulations show that reducing the amperage rating of the protective fuse does increase fault current detection sensitivity without increasing the likelihood of nuisance trips to a degree. Unfortunately, this benefit reaches a limit as fuses become smaller and their internal resistance increases to the point of becoming a major element in the fault current circuit.

Calculation of the fast ion tail distribution for a spherically symmetric hot spot  

SciTech Connect

The fast ion tail for a spherically symmetric hot spot is computed via the solution of a simplified Fokker-Planck collision operator. Emphasis is placed on describing the energy scaling of the fast ion distribution function in the hot spot as well as the surrounding cold plasma throughout a broad range of collisionalities and temperatures. It is found that while the fast ion tail inside the hot spot is significantly depleted, leading to a reduction of the fusion yield in this region, a surplus of fast ions is observed in the neighboring cold plasma region. The presence of this surplus of fast ions in the neighboring cold region is shown to result in a partial recovery of the fusion yield lost in the hot spot.

Hot-spot measurements on the US-LCT coils in the IFSMTF  

SciTech Connect

Hot-spot temperature during a quench is a major concern for superconducting coil protection. If the allowable temperature can be increased, then the dump time constant can be made longer and the dump voltage correspondingly reduced. Thus, the insulation requirement can be less stringent and the dump operation can be safer. The US-made Large Coil Task (LCT) coils are all instrumented with heaters, resistive or inductive. The hot-spot temperatures of these coils were found by repeatedly driving the conductor normal with the heaters at increasing coil currents until the normal zone propagated. The resulting hot-spot temperature was measured by the resistance of the conductor over a fixed length. The effect of dump time delay on the hot-spot temperature was also investigated. The results are compared with calculations based on various assumptions. 4 refs., 7 figs.

A Multivariate Moving Average Control Chart for Photovoltaic Processes  

E-Print Network (OSTI)

Abstract—For the electrical metrics that describe photovoltaic cell performance are inherently multivariate in nature, use of a univariate, or one variable, statistical process control chart can have important limitations. Development of a comprehensive process control strategy is known to be significantly beneficial to reducing process variability that ultimately drives up the manufacturing cost photovoltaic cells. The multivariate moving average or MMA chart, is applied to the electrical metrics of photovoltaic cells to illustrate the improved sensitivity on process variability this method of control charting offers. The result show the ability of the MMA chart to expand to as any variables as needed, suggests an application with multiple photovoltaic electrical metrics being used in concert to determine the processes state of control.

Yearly-averaged daily usefulness efficiency of heliostat surfaces  

SciTech Connect

An analytical expression for estimating the instantaneous usefulness efficiency of a heliostat surface is obtained. A systematic procedure is then introduced to calculate the usefulness efficiency even when overlapping of blocking and shadowing on a heliostat surface exist. For possible estimation of the reflected energy from a given field, the local yearly-averaged daily usefulness efficiency is calculated. This efficiency is found to depend on site latitude angle, radial distance from the tower measured in tower heights, heliostat position azimuth angle and the radial spacing between heliostats. Charts for the local yearly-averaged daily usefulness efficiency are presented for {phi} = 0, 15, 30, and 45 N. These charts can be used in calculating the reflected radiation from a given cell. Utilization of these charts is demonstrated.

The averaged null energy conditions (ANEC) states that, along a complete null curve, the negative energy fluctuations of a quantum field must be balanced by positive energy fluctuations. We use the AdS/CFT correspondence to prove the ANEC for a class of strongly coupled conformal field theories in flat spacetime. A violation of the ANEC in the field theory would lead to acausal propagation of signals in the bulk.

Testing a class of non-Kerr metrics with hot spots orbiting SgrA$^*$  

E-Print Network (OSTI)

SgrA$^*$, the supermassive black hole candidate at the Galactic Center, exhibits flares in the X-ray, NIR, and sub-mm bands that may be interpreted within a hot spot model. Light curves and images of hot spots orbiting a black hole are affected by a number of special and general relativistic effects, and they can be potentially used to check whether the object is a Kerr black hole of general relativity. However, in a previous study we have shown that the relativistic features are usually subdominant with respect to the background noise and the model-dependent properties of the hot spot, and eventually it is at most possible to estimate the frequency of the innermost stable circular orbit. In this case, tests of the Kerr metric are only possible in combination with other measurements. In the present work, we consider a class of non-Kerr spacetimes in which the hot spot orbit may be outside the equatorial plane. If the hot spot is sufficiently close to the massive object, the image affected by Doppler blueshift is brighter than the other one and this provides a specific observational signature in the hot spot's centroid track. We conclude that accurate astrometric observations of SgrA$^*$ with an instrument like GRAVITY should be able to test this class of metrics, except in the more unlikely case of a small viewing angle.

High Average Power, High Energy Short Pulse Fiber Laser System  

SciTech Connect

Recently continuous wave fiber laser systems with output powers in excess of 500W with good beam quality have been demonstrated [1]. High energy, ultrafast, chirped pulsed fiber laser systems have achieved record output energies of 1mJ [2]. However, these high-energy systems have not been scaled beyond a few watts of average output power. Fiber laser systems are attractive for many applications because they offer the promise of high efficiency, compact, robust systems that are turn key. Applications such as cutting, drilling and materials processing, front end systems for high energy pulsed lasers (such as petawatts) and laser based sources of high spatial coherence, high flux x-rays all require high energy short pulses and two of the three of these applications also require high average power. The challenge in creating a high energy chirped pulse fiber laser system is to find a way to scale the output energy while avoiding nonlinear effects and maintaining good beam quality in the amplifier fiber. To this end, our 3-year LDRD program sought to demonstrate a high energy, high average power fiber laser system. This work included exploring designs of large mode area optical fiber amplifiers for high energy systems as well as understanding the issues associated chirped pulse amplification in optical fiber amplifier systems.

Use of treatment log files in spot scanning proton therapy as part of patient-specific quality assurance  

SciTech Connect

Purpose: The purpose of this work was to assess the monitor unit (MU) values and position accuracy of spot scanning proton beams as recorded by the daily treatment logs of the treatment control system, and furthermore establish the feasibility of using the delivered spot positions and MU values to calculate and evaluate delivered doses to patients. Methods: To validate the accuracy of the recorded spot positions, the authors generated and executed a test treatment plan containing nine spot positions, to which the authors delivered ten MU each. The spot positions were measured with radiographic films and Matrixx 2D ion-chambers array placed at the isocenter plane and compared for displacements from the planned and recorded positions. Treatment logs for 14 patients were then used to determine the spot MU values and position accuracy of the scanning proton beam delivery system. Univariate analysis was used to detect any systematic error or large variation between patients, treatment dates, proton energies, gantry angles, and planned spot positions. The recorded patient spot positions and MU values were then used to replace the spot positions and MU values in the plan, and the treatment planning system was used to calculate the delivered doses to patients. The results were compared with the treatment plan. Results: Within a treatment session, spot positions were reproducible within {+-}0.2 mm. The spot positions measured by film agreed with the planned positions within {+-}1 mm and with the recorded positions within {+-}0.5 mm. The maximum day-to-day variation for any given spot position was within {+-}1 mm. For all 14 patients, with {approx}1 500 000 spots recorded, the total MU accuracy was within 0.1% of the planned MU values, the mean (x, y) spot displacement from the planned value was (-0.03 mm, -0.01 mm), the maximum (x, y) displacement was (1.68 mm, 2.27 mm), and the (x, y) standard deviation was (0.26 mm, 0.42 mm). The maximum dose difference between calculated dose to the patient based on the plan and recorded data was within 2%. Conclusions: The authors have shown that the treatment log file in a spot scanning proton beam delivery system is precise enough to serve as a quality assurance tool to monitor variation in spot position and MU value, as well as the delivered dose uncertainty from the treatment delivery system. The analysis tool developed here could be useful for assessing spot position uncertainty and thus dose uncertainty for any patient receiving spot scanning proton beam therapy.

Hilbert Space Average Method and adiabatic quantum search  

E-Print Network (OSTI)

We discuss some aspects related to the so-called Hilbert space Average Method, as an alternative to describe the dynamics of open quantum systems. First we present a derivation of the method which does not make use of the algebra satisfied by the operators involved in the dynamics, and extend the method to systems subject to a Hamiltonian that changes with time. Next we examine the performance of the adiabatic quantum search algorithm with a particular model for the environment. We relate our results to the criteria discussed in the literature for the validity of the above-mentioned method for similar environments.

Magnetic dipole discharges. II. Cathode and anode spot discharges and probe diagnostics  

SciTech Connect

The high current regime of a magnetron-type discharge has been investigated. The discharge uses a permanent magnet as a cold cathode which emits secondary electrons while the chamber wall or a grounded electrode serves as the anode. As the discharge voltage is increased, the magnet develops cathode spots, which are short duration arcs that provide copious electrons to increase the discharge current dramatically. Short (1 ?s), high current (200 A) and high voltage (750 V) discharge pulses are produced in a relaxation instability between the plasma and a charging capacitor. Spots are also observed on a negatively biased plane Langmuir probe. The probe current pulses are as large as those on the magnet, implying that the high discharge current does not depend on the cathode surface area but on the properties of the spots. The fast current pulses produce large inductive voltages, which can reverse the electrical polarity of the magnet and temporarily operate it as an anode. The discharge current may also oscillate at the frequency determined by the charging capacitor and the discharge circuit inductance. Each half cycle of high-current current pulses exhibits a fast (?10 ns) current rise when a spot is formed. It induces high frequency (10–100 MHz) transients and ringing oscillations in probes and current circuits. Most probes behave like unmatched antennas for the electromagnetic pulses of spot discharges. Examples are shown to distinguish the source of oscillations and some rf characteristics of Langmuir probes.

Testing a class of non-Kerr metrics with hot spots orbiting SgrA$^*$  

E-Print Network (OSTI)

SgrA$^*$, the supermassive black hole candidate at the Galactic Center, exhibits flares in the X-ray, NIR, and sub-mm bands that may be interpreted within a hot spot model. Light curves and images of hot spots orbiting a black hole are affected by a number of special and general relativistic effects, and they can be potentially used to check whether the object is a Kerr black hole of general relativity. However, in a previous study we have shown that the relativistic features are usually subdominant with respect to the background noise and the model-dependent properties of the hot spot, and eventually it is at most possible to estimate the frequency of the innermost stable circular orbit. In this case, tests of the Kerr metric are only possible in combination with other measurements. In the present work, we consider a class of non-Kerr spacetimes in which the hot spot orbit may be outside the equatorial plane. If the hot spot is sufficiently close to the massive object, the image affected by Doppler blueshift...

Highlights Highlights After falling by more than 40 cents per gallon from the beginning of September through mid-November, weekly U.S. average regular gasoline retail prices increased by 8 cents per gallon to reach $3.27 per gallon on December 2, 2013, due in part to unplanned refinery maintenance and higher crude oil prices. The annual average regular gasoline retail price, which was $3.63 per gallon in 2012, is expected to average $3.50 per gallon in 2013 and $3.43 per gallon in 2014. The North Sea Brent crude oil spot price averaged near $110 per barrel for the fifth consecutive month in November. EIA expects the Brent crude oil price to average $108 per barrel in December and decline gradually to $104 per barrel in 2014. Projected West Texas Intermediate (WTI) crude oil prices average $95 per barrel during 2014.

Average System Cost Methodology : Administrator's Record of Decision.  

SciTech Connect

Significant features of average system cost (ASC) methodology adopted are: retention of the jurisdictional approach where retail rate orders of regulartory agencies provide primary data for computing the ASC for utilities participating in the residential exchange; inclusion of transmission costs; exclusion of construction work in progress; use of a utility's weighted cost of debt securities; exclusion of income taxes; simplification of separation procedures for subsidized generation and transmission accounts from other accounts; clarification of ASC methodology rules; more generous review timetable for individual filings; phase-in of reformed methodology; and each exchanging utility must file under the new methodology within 20 days of implementation by the Federal Energy Regulatory Commission of the ten major participating utilities, the revised ASC will substantially only affect three.

Powerful Radio Galaxies with Simbol-X: Lobes and Hot Spots  

SciTech Connect

We present here the first Simbol-X simulations of the extended components, lobes and hot spots, of the radio galaxies. We use the paradigmatic case of Pictor A to test the capabilities of Simbol-X in this field of studies. Simulations demonstrate that Simbol-X will be able not only to perform spatially resolved studies on the lobes of radio galaxies below 10 keV but also to observe, for the first time, hard X-ray emission from the hot spots. These extremely promising results show the considerable potentiality of Simbol-X in studying interaction phenomena between relativistic plasma and surrounding environment.

Ensemble bayesian model averaging using markov chain Monte Carlo sampling  

SciTech Connect

Bayesian model averaging (BMA) has recently been proposed as a statistical method to calibrate forecast ensembles from numerical weather models. Successful implementation of BMA however, requires accurate estimates of the weights and variances of the individual competing models in the ensemble. In their seminal paper (Raftery etal. Mon Weather Rev 133: 1155-1174, 2(05)) has recommended the Expectation-Maximization (EM) algorithm for BMA model training, even though global convergence of this algorithm cannot be guaranteed. In this paper, we compare the performance of the EM algorithm and the recently developed Differential Evolution Adaptive Metropolis (DREAM) Markov Chain Monte Carlo (MCMC) algorithm for estimating the BMA weights and variances. Simulation experiments using 48-hour ensemble data of surface temperature and multi-model stream-flow forecasts show that both methods produce similar results, and that their performance is unaffected by the length of the training data set. However, MCMC simulation with DREAM is capable of efficiently handling a wide variety of BMA predictive distributions, and provides useful information about the uncertainty associated with the estimated BMA weights and variances.

Short-Term World Oil Price Forecast  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: This graph shows monthly average spot West Texas Intermediate crude oil prices. Spot WTI crude oil prices peaked last fall as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. So where do we see crude oil prices going from here? Crude oil prices are expected to be about $28-$30 per barrel for the rest of this year, but note the uncertainty bands on this projection. They give an indication of how difficult it is to know what these prices are going to do. Also, EIA does not forecast volatility. This relatively flat forecast could be correct on average, with wide swings around the base line. Let's explore why we think prices will likely remain high, by looking at an important market barometer - inventories - which measures the

4, 2002 (next release 2:00 p.m. on October 4, 2002 (next release 2:00 p.m. on October 31) A second early season cold front caused heating demand that increased prices at key market centers in the Northeast and West Coast up to 42 cents per MMBtu since October 16. The higher aggregate demand lifted natural gas spot prices 10 to 25 cents at most production-area trading locations. For the week (Wednesday-Wednesday), the average Henry Hub price climbed $0.14 per MMBtu to $4.24. At the NYMEX, the futures contract for November delivery at the Henry Hub increased a more moderate $0.033 per MMBtu to a $4.260 settlement yesterday (October 23). Natural gas in storage increased to 3,161 Bcf for the week ending October 18, which exceeds the 5-year average by 7.4 percent. The spot price for West Texas Intermediate (WTI)

Integrated thermal-microstructure model to predict the property gradients in resistance spot steel welds  

SciTech Connect

An integrated model approach was proposed for relating resistance welding parameters to weldment properties. An existing microstructure model was used to determine the microstructural and property gradients in resistance spot welds of plain carbon steel. The effect of these gradients on the weld integrity was evaluated with finite element analysis. Further modifications to this integrated thermal-microstructure model are discussed.

Short-lived spots in solar-like stars as observed by CoRoT  

E-Print Network (OSTI)

Context. CoRoT light curves have an unprecedented photometric quality, having simultaneously a high signal-to-noise ratio, a long time span and a nearly continuous duty-cycle. Aims. We analyse the light-curves of four bright targets observed in the seismology field and study short-lived small spots in solar-like stars. Methods. We present a simple spot modeling by iterative analysis. Its ability to extract relevant parameters is ensured by implementing relaxation steps to avoid convergence to local minima of the sum of the residuals between observations and modeling. The use of Monte-Carlo simulations allows us to estimate the performance of the fits. Results. Our starspot modeling gives a representation of the spots on these stars in agreement with other well tested methods. Within this framework, parameters such as rigid-body rotation and spot lifetimes seem to be precisely determined. Then, the lifetime/rotation period ratios are in the range 0.5 - 2, and there is clear evidence for differential rotation.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

12 (next release 2:00 p.m. on May 19) 12 (next release 2:00 p.m. on May 19) Spot and futures natural gas prices this week (Wednesday-Wednesday, May 4-11) partly recovered from the prior week's sharp decline, owing to warmer temperatures moving into parts of the South and cool temperatures in the Rockies. The Henry Hub spot price increased 14 cents per MMBtu to $6.63. The New York Mercantile Exchange (NYMEX) futures contract for June delivery at the Henry Hub was higher on the week by about 5 cents per MMBtu, closing yesterday (May 11) at $6.683. Natural gas in storage as of Friday, May 6, increased to 1,509 Bcf, which is 22.3 percent above the 5-year average. Before declining sharply yesterday, crude oil spot prices appeared to be supporting higher natural gas prices, with the West Texas Intermediate (WTI) price increasing more than $1.50 per barrel since Wednesday (May 4) to over $52. The net change in the WTI price on the week was 17 cents per MMBtu, or less than 1 percent, as the price dropped $1.37 per barrel yesterday to $50.39 per barrel, or $8.69 per MMBtu.

11, 2003 (next release 2:00 p.m. on September 18) 11, 2003 (next release 2:00 p.m. on September 18) Spot natural gas prices increased 5 to 15 cents in most regional markets for the week (Wednesday to Wednesday, September 3-10). The Henry Hub spot price gained 10 cents on the week, ending trading yesterday (Wednesday, September 10) at $4.78 per MMBtu. Futures prices were up as well, with the gains owing almost entirely to yesterday's large price increases. The NYMEX futures contract for October delivery moved up nearly 24 cents in yesterday's trading, and for the week gained $0.278 per MMBtu with its settlement yesterday at $4.968. The Energy Information Administration (EIA) reported that inventories were 2,486 Bcf as of Friday, September 5, which is 5.5 percent less than the 5-year (1998-2002) average. The spot price for West Texas Intermediate (WTI) crude oil fell below $29 per barrel for the first time since late June, lingering in the high-$28s for the first 3 days of the week before regaining nearly all of its decreases on Tuesday and Wednesday. WTI crude oil ended the week at $29.41 per barrel ($5.07 per MMBtu), just 2 cents per barrel below the week-ago price.

23, 2002 (next release 2:00 p.m. on May 30) 23, 2002 (next release 2:00 p.m. on May 30) Natural gas spot and futures prices trended down for the week (Wednesday to Wednesday, May 15-22). The cold front that moved into major gas-consuming areas of the Midwest and Northeast for the weekend and lingered into the first part of this week had minimal impact on prices. At the Henry Hub, the average spot price fell 24 cents for the week to $3.38 per MMBtu. On the NYMEX, the settlement price of the near-month contract (June delivery) declined for 5 straight trading sessions before recording a small increase of $0.064 per MMBtu in May 22 trading, to settle at $3.459. The spot price for West Texas Intermediate (WTI) crude oil, which had held at or above $28 per barrel since last Thursday, fell nearly $1 on Tuesday, May 21, following the American Petroleum Institute's announcement of an unexpected build in crude oil stocks of 5.5 million barrels for the week ended Friday, May 17. For the week (May 15-22), the WTI price was down $0.99, at $27.01 per barrel, or $4.66 per MMBtu.

Experimental investigation of bright spots in broadband, gated x-ray images of ignition-scale implosions on the National Ignition Facility  

SciTech Connect

Bright spots in the hot spot intensity profile of gated x-ray images of ignition-scale implosions at the National Ignition Facility [G. H. Miller et al., Opt. Eng. 443, (2004)] are observed. X-ray images of cryogenically layered deuterium-tritium (DT) and tritium-hydrogen-deuterium (THD) ice capsules, and gas filled plastic shell capsules (Symcap) were recorded along the hohlraum symmetry axis. Heterogeneous mixing of ablator material and fuel into the hot spot (i.e., hot-spot mix) by hydrodynamic instabilities causes the bright spots. Hot-spot mix increases the radiative cooling of the hot spot. Fourier analysis of the x-ray images is used to quantify the evolution of bright spots in both x- and k-space. Bright spot images were azimuthally binned to characterize bright spot location relative to known isolated defects on the capsule surface. A strong correlation is observed between bright spot location and the fill tube for both Symcap and cryogenically layered DT and THD ice targets, indicating the fill tube is a significant seed for the ablation front instability causing hot-spot mix. The fill tube is the predominant seed for Symcaps, while other capsule non-uniformities are dominant seeds for the cryogenically layered DT and THD ice targets. A comparison of the bright spot power observed for Si- and Ge-doped ablator targets shows heterogeneous mix in Symcap targets is mostly material from the doped ablator layer.

19, 2002 (next release 2:00 p.m. on September 26) 19, 2002 (next release 2:00 p.m. on September 26) Spot and futures prices surged upward as two tropical storms in close succession made their presence felt in gas markets over the past week. At the Henry Hub, the average spot price rose 47 cents week-to-week (Wednesday, September 11 to Wednesday, September 18) to $3.79 per MMBtu, which is at its highest level since May 1. In addition to some production shut-ins from Tropical Storm Hanna's arrival in the Gulf of Mexico on Friday (September 13), spot prices were also bolstered somewhat by warmer-than-normal temperatures in most regions since last Wednesday, as well as by outages of a number of nuclear-fired electric plants for routine maintenance. On the NYMEX, the settlement price of the futures contract for October delivery rose in five consecutive trading sessions, reaching a 4-month high yesterday at $3.787 per MMBtu. Natural gas in storage increased by 69 Bcf to 2,924 Bcf, 12 percent above the 5-year average. After falling 82 cents on Thursday (September 12) to dip below $29 per barrel, the spot price of West Texas Intermediate (WTI) crude oil rebounded strongly on Friday and remained above the $29 per barrel mark for the rest of the week, ending trading yesterday at $29.57 per barrel, or $5.10 per MMBtu. This is a decline of 20 cents per barrel from the WTI spot price of last Wednesday.

Operating conditions for the generation of stable anode spot plasma in front of a positively biased electrode  

SciTech Connect

Stability of an anode spot plasma, which is an additional high density plasma generated in front of a positively biased electrode immersed in ambient plasma, is a critical issue for its utilization to various types of ion sources. In this study, operating conditions for the generation of stable anode spot plasmas are experimentally investigated. Diagnostics of the bias current flowing into the positively biased electrode and the properties of ambient plasma reveal that unstable nature of the anode spot is deeply associated with the reduction of double layer potential between the anode spot plasma and the ambient plasma. It is found that stability of the anode spot plasma can be improved with increasing the ionization rate in ambient plasma so as to compensate the loss of electrons across the double layer or with enlarging the area of the biased electrode to prevent electron accumulation inside the anode spot. The results obtained from the present study give the guideline for operating conditions of anode spot plasmas as an ion source with high brightness.

Linear and non-linear Granger causality between oil spot and futures prices: A wavelet based test  

Science Journals Connector (OSTI)

Abstract This study is the first attempt to investigate both the linear and non-linear Granger causality between wavelet transformed spot and futures oil prices. Our findings consistently indicate bidirectional causality between the spot and futures oil markets at different time scales, under linear and non-linear causality assumptions, and also during the recent financial crisis. Our results tend to shed further light on the ongoing controversy over the relative price discovery role played by spot market as opposed to futures market in oil price fluctuations, especially during periods of high uncertainty.

Spot test for 1,3,5-triamino-2,4,6-trinitrobenzene, TATB  

DOE Patents (OSTI)

A simple, sensitive and specific spot test for 1,3,5-triamino-2,4,6-trinitrobenzene, TATB, is described. Upon the application of the composition of matter of the subject invention to samples containing in excess of 0.1 mg of this explosive, a bright orange color results. Interfering species such as TNT and Tetryl can be removed by first treating the sample with a solvent which does not dissolve the TATB, but readily dissolves these interfering explosives.

Eutectic structures in friction spot welding joint of aluminum alloy to copper  

SciTech Connect

A dissimilar joint of AA5083 Al alloy and copper was produced by friction spot welding. The Al-MgCuAl{sub 2} eutectic in both coupled and divorced manners were found in the weld. At a relatively high temperature, mass transport of Cu due to plastic deformation, material flow, and atomic diffusion, combined with the alloy system of AA5083 are responsible for the ternary eutectic melting.

Friction Stir Spot Welding (FSSW) of Advanced High Strength Steel (AHSS)  

SciTech Connect

Friction stir spot welding (FSSW) is applied to join advanced high strength steels (AHSS): galvannealed dual phase 780 MPa steel (DP780GA), transformation induced plasticity 780 MPa steel (TRIP780), and hot-stamped boron steel (HSBS). A low-cost Si3N4 ceramic tool was developed and used for making welds in this study instead of polycrystalline cubic boron nitride (PCBN) material used in earlier studies. FSSW has the advantages of solid-state, low-temperature process, and the ability of joining dissimilar grade of steels and thicknesses. Two different tool shoulder geometries, concave with smooth surface and convex with spiral pattern, were used in the study. Welds were made by a 2-step displacement control process with weld time of 4, 6, and 10 seconds. Static tensile lap-shear strength achieved 16.4 kN for DP780GA-HSBS and 13.2kN for TRIP780-HSBS, above the spot weld strength requirements by AWS. Nugget pull-out was the failure mode of the joint. The joining mechanism was illustrated from the cross-section micrographs. Microhardness measurement showed hardening in the upper sheet steel (DP780GA or TRIP780) in the weld, but softening of HSBS in the heat-affect zone (HAZ). The study demonstrated the feasibility of making high-strength AHSS spot welds with low-cost tools.

9 (next release 2:00 p.m. on December 16) 9 (next release 2:00 p.m. on December 16) Both natural gas spot and futures prices fell significantly over the week (Wednesday to Wednesday, December 1-8), as temperatures in most major gas-consuming areas of the nation were above normal most days, with differences reaching double digits in the past several days in many locations east of the Mississippi River. The Henry Hub spot price fell 79 cents per MMBtu, or nearly 12 percent, since last Wednesday (December 1) trading yesterday (Wednesday, December 8) at $5.98. The NYMEX futures contract for January 2005 delivery declined by a similar amount for the week (73 cents per MMBtu), settling yesterday) at $6.683 per MMBtu, or about 10 percent less than last Wednesday's settlement price ($7.413). EIA reported that inventories were 3,211 Bcf as of Friday, December 3, which is 12 percent greater than the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil fell by over $3 per barrel for the second week in a row, declining in 4 of 5 trading days and ending the week down $3.60 per barrel ($0.62 per MMBtu), at yesterday's price of $41.96 ($7.23). Since reaching its record-high spot price of $56.37 per barrel on October 26, the WTI spot price has declined in 5 of the 6 ensuing weeks, with yesterday's price representing a nearly26 percent drop in value.

Resistance Spot Welding of Aluminum Alloy to Steel with Transition Material - From Process to Performance  

SciTech Connect

This paper summarizes work to date on resistance spot welding (RSW) of aluminum alloy to mild steel from process development to performance evaluation. A cold-rolled strip material is introduced as a transition material to aid the resistance welding process. The optimal welding parameters and electrode selections were established using a combination of experimental and analytical approaches. The mechanical behaviors of welded samples was evaluated using static and dynamic strength tests and cyclic fatigue tests. A statistical analysis was also performed to analyze the effect of different failure modes on the sample's peak load and energy absorption.

Matter seen at many scales and the geometry of averaging in relativistic cosmology  

E-Print Network (OSTI)

We investigate the scale-dependence of Eulerian volume averages of scalar functions on Riemannian three-manifolds. We propose a complementary view of a Lagrangian scaling of variables as opposed to their Eulerian averaging on spatial domains. This program explains rigorously the origin of the Ricci deformation flow for the metric, a flow which, on heuristic grounds, has been already suggested as a possible candidate for averaging the initial data set for cosmological spacetimes.

STEO January 2013 - world oil prices  

U.S. Energy Information Administration (EIA) Indexed Site

Gap between U.S. and world oil prices to be cut by more than Gap between U.S. and world oil prices to be cut by more than half over next two years The current wide price gap between a key U.S. and a world benchmark crude oil is expected to narrow significantly over the next two years. The spot price for U.S. benchmark West Texas Intermediate crude oil, also known as WTI , averaged $94 a barrel in 2012. That's $18 less than North Sea Brent oil, which is a global benchmark crude that had an average price of $112 last year. The new monthly forecast from the U.S. Energy Information Administration expects the price gap between the two crude oils to shrink to $16 a barrel this year and then to $8 in 2014. That's when WTI would average $91 a barrel and Brent would be at $99. The smaller price gap will result from new pipelines coming on line that will lower the cost of

Friday, January 3, 2003 (next release 2:00 p.m. on January 9) Friday, January 3, 2003 (next release 2:00 p.m. on January 9) A trend of generally declining natural gas spot prices across the country since mid-December came to an abrupt halt yesterday (Thursday, January 2) owing to new forecasts of an Arctic front expected to arrive soon in the Lower 48. During the first day of trading in the New Year, the Henry Hub spot price moved up 34 cents per MMBtu to $4.94, but was still 6 cents lower in comparison with the average last Thursday. For the week (Thursday-Thursday), the price of the NYMEX futures contract for February increased just over $0.26 per MMBtu to $5.251. Natural gas in storage decreased to 2,417 Bcf, which trails the 5-year average by 3.8 percent, for the week ending December 27. Crude oil prices have provided little reprieve from the cautious energy outlook for the rest of the winter, as they continue to hover around 2-year highs owing to political strife in Venezuela and the Iraqi situation, both of which contribute to supply concerns for U.S. markets. Although the spot price for West Texas Intermediate (WTI) crude oil declined $0.64 per barrel on the week, the spot price gained $0.76 yesterday to an average of $31.97, or $5.51 per MMBtu.

Pulse shaping effects on weld porosity in laser beam spot welds : contrast of long- & short- pulse welds.  

SciTech Connect

Weld porosity is being investigated for long-pulse spot welds produced by high power continuous output lasers. Short-pulse spot welds (made with a pulsed laser system) are also being studied but to a much small extent. Given that weld area of a spot weld is commensurate with weld strength, the loss of weld area due to an undefined or unexpected pore results in undefined or unexpected loss in strength. For this reason, a better understanding of spot weld porosity is sought. Long-pulse spot welds are defined and limited by the slow shutter speed of most high output power continuous lasers. Continuous lasers typically ramp up to a simmer power before reaching the high power needed to produce the desired weld. A post-pulse ramp down time is usually present as well. The result is a pulse length tenths of a second long as oppose to the typical millisecond regime of the short-pulse pulsed laser. This study will employ a Lumonics JK802 Nd:YAG laser with Super Modulation pulse shaping capability and a Lasag SLS C16 40 W pulsed Nd:YAG laser. Pulse shaping will include square wave modulation of various peak powers for long-pulse welds and square (or top hat) and constant ramp down pulses for short-pulse welds. Characterization of weld porosity will be performed for both pulse welding methods.

The Influence of spot size on the expansion dynamics of nanosecond-laser-produced copper plasmas in atmosphere  

SciTech Connect

Laser produced copper plasmas of different spot sizes in air were investigated using fast photography and optical emission spectroscopy (OES). The laser energy was 33 mJ. There were dramatic changes in the plasma plume expansion into the ambient air when spot sizes changed from {approx}0.1 mm to {approx}0.6 mm. A stream-like structure and a hemispherical structure were, respectively, observed. It appeared that the same spot size resulted in similar expansion dynamics no matter whether the target was located in the front of or behind the focal point, although laser-induced air breakdown sometimes occurred in the latter case. Plasma plume front positions agree well with the classic blast wave model for the large spot-size cases, while an unexpected stagnation of {approx}80 ns occurred after the laser pulse ends for the small spot size cases. This stagnation can be understood in terms of the evolution of enhanced plasma shielding effects near the plasma front. Axial distributions of plasma components by OES revealed a good confinement effect. Electron number densities were estimated and interpreted using the recorded Intensified Charge Coupled Device (ICCD) images.

DEFINING THE 'BLIND SPOT' OF HINODE EIS AND XRT TEMPERATURE MEASUREMENTS  

SciTech Connect

Observing high-temperature, low emission measure plasma is key to unlocking the coronal heating problem. With current instrumentation, a combination of EUV spectral data from Hinode Extreme-ultraviolet Imaging Spectrometer (EIS; sensitive to temperatures up to 4 MK) and broadband filter data from Hinode X-ray Telescope (XRT; sensitive to higher temperatures) is typically used to diagnose the temperature structure of the observed plasma. In this Letter, we demonstrate that a 'blind spot' exists in temperature-emission measure space for combined Hinode EIS and XRT observations. For a typical active region core with significant emission at 3-4 MK, Hinode EIS and XRT are insensitive to plasma with temperatures greater than {approx}6 MK and emission measures less than {approx}10{sup 27} cm{sup -5}. We then demonstrate that the temperature and emission measure limits of this blind spot depend upon the temperature distribution of the plasma along the line of sight by considering a hypothetical emission measure distribution sharply peaked at 1 MK. For this emission measure distribution, we find that EIS and XRT are insensitive to plasma with emission measures less than {approx}10{sup 26} cm{sup -5}. We suggest that a spatially and spectrally resolved 6-24 Angstrom-Sign spectrum would improve the sensitivity to these high-temperature, low emission measure plasma.

Joint strength in high speed friction stir spot welded DP 980 steel  

SciTech Connect

High speed friction stir spot welding was applied to 1.2 mm thick DP 980 steel sheets under different welding conditions, using PCBN tools. The range of vertical feed rates used during welding was 2.5 mm – 102 mm per minute, while the range of spindle speeds was 2500 – 6000 rpm. Extended testing was carried out for five different sets of welding conditions, until tool failure. These welding conditions resulted in vertical welding loads of 3.6 – 8.2 kN and lap shear tension failure loads of 8.9 – 11.1 kN. PCBN tools were shown, in the best case, to provide lap shear tension fracture loads at or above 9 kN for 900 spot welds, after which tool failure caused a rapid drop in joint strength. Joint strength was shown to be strongly correlated to bond area, which was measured from weld cross sections. Failure modes of the tested joints were a function of bond area and softening that occurred in the heat-affected zone.

Wear testing of friction stir spot welding tools for joining of DP 980 Steel  

SciTech Connect

Friction stir spot welding has been shown to be a viable method of joining ultra high strength steel (UHSS), both in terms of joint strength and process cycle time. However, the cost of tooling must be reasonable in order for this method to be adopted as an industrial process. Several tooling materials have been evaluated in prior studies, including silicon nitride and polycrystalline cubic boron nitride (PCBN). Recently a new tool alloy has been developed, where a blend of PCBN and tungsten rhenium (W-Re) was used in order to improve the toughness of the tool. Wear testing results are presented for two of these alloys: one with a composition of 60% PCBN and 40% W-Re (designated as Q60), and one with 70% PCBN and 30% W-Re (designated at Q70). The sheet material used for all wear testing was DP 980. Tool profiles were measured periodically during the testing process in order to show the progression of wear as a function of the number of spots produced. Lap shear testing was done each time a tool profile was taken in order to show the relationship between tool wear and joint strength. For the welding parameters chosen for this study the Q70 tool provided the best combination of wear resistance and joint strength.

Monitoring seasonal and annual wetland changes in a freshwater marsh with SPOT HRV data  

SciTech Connect

Eleven dates of SPOT HRV data along with near-concurrent vertical aerial photographic and phenological data for 1987, 1988, and 1989 were evaluated to determine seasonal and annual changes in a 400-hectare, southeastern freshwater marsh. Early April through mid-May was the best time to discriminate among the cypress (Taxodium distichum)/water tupelo (Nyssa acquatica) swamp forest and the non-persistent (Ludwigia spp.) and persistent (Typha spp.) stands in this wetlands. Furthermore, a ten-fold decrease in flow rate from 11 cubic meters per sec (cms) in 1987 to one cms in 1988 was recorded in the marsh followed by a shift to drier wetland communities. The Savannah River Site (SRS), maintained by the US Department of Energy, is a 777 km{sup 2} area located in south central South Carolina. Five tributaries of the Savannah River run southwest through the SRS and into the floodplain swamp of the Savannah River. This paper describes the use of SPOT HRV data to monitor seasonal and annual trends in one of these swamp deltas, Pen Branch Delta, during a three-year period, 1987--1989.

The average spot price at the Henry Hub yesterday (Wednesday, October 2), at $4.24 per MMBtu, was 49 cents higher than a week ago. However, the amount of gas actually delivered at October 2 prices is likely to be small, as operations at the Henry Hub near Erath, LA, were essentially shut down for at least 48 hours because of Lili's impending arrival. On the NYMEX, the expiring near-month contract for October delivery ended trading on Thursday, September 26 with a sizeable gain of over 19 cents per MMBtu, closing at $3.686. Taking over as the near-month contract, the futures contract for November delivery promptly gained $0.152 per MMBtu to settle at $4.041 on Friday. Natural gas in storage reached 3,038 Bcf on September 27, which exceeds the average of the past 5 years by 10 percent. With continuing turmoil in the Middle East and uncertainty surrounding the conflict with Iraq over weapons inspections keeping oil prices high, the spot price of West Texas Intermediate (WTI) crude oil hovered above $30 per barrel throughout the week. WTI ended trading Wednesday (October 2) at an average of $30.59 per barrel, or about $5.27 per MMBtu, down a dime per barrel from the previous Wednesday.
