VisTool: a Visual Tool for Querying Relational Databases  

E-Print Network (OSTI)

In this paper we describe VisTool, a prototype tool for querying relational databases by means of the visual query language VISIONARY. INTRODUCTION VISIONARY [1] is based on an iconic-diagrammatic paradigm used for both data and query representation. The external data model is called vision and is made up of the visual primitives of concept and association; the external query model is based on the definition of a dynamic and adaptive perspective for accessing data. The internal data model is relational, and the internal query model is SQL. The mapping between the visual and the relational worlds is established through an intermediate graph-based level. VISIONARY is mainly directed to naive and occasional users, who have no experience with data models and only have a general idea about the contents of the database; for this reason, the expressive power of VISIONARY is limited...

Variable Interactions in Query-Driven Visualization  

SciTech Connect

One fundamental element of scientific inquiry is discoveringrelationships, particularly the interactions between different variablesin observed or simulated phenomena. Building upon our prior work in thefield of Query-Driven Visualization, where visual data analysisprocessing is focused on subsets of large data deemed to be"scientifically interesting," this new work focuses on a novel knowledgediscovery capability suitable for use with petascale class datasets. Itenables visual presentation of the presence or absence of relationships(correlations) between variables in data subsets produced by Query-Drivenmethodologies. This technique holds great potential for enablingknowledge discovery from large and complex datasets currently emergingfrom SciDAC and INCITE projects. It is sufficiently generally to beapplicable to any time of complex, time-varying, multivariate data fromstructured, unstructured or adaptive grids.

An interactive visual query interface on spatial/ temporal data  

E-Print Network (OSTI)

Abstract: In this paper a visual approach for the query interface on the spatial/temporal data is described, which is designed for the users who know nothing about query languages. Based on concept of elementary query and query operators, a complex spatial/temporal query could be built as a compound query which is broken down into several interactive iterations. In each of iterations, users just need to build a simple elementary query and select a query operator, which greatly reduces the mental load of users. To make query building more efficient, a novel approach based on the query pattern retrieving and matching is explained and used in the interface. An experimental prototype has been implemented to demonstrate the usability of the interface.

MetaBrowser: A combined browsing, query, and analysis tool  

SciTech Connect

The MetaBrowser design is based on the premise that scientists should not be forced to learn new languages or commands for finding the data they are interested in and for selecting subsets of the data for further analysis. Furthermore, there should be a single system that permits browsing, query, and analysis of the data, so that the scientist does not have to switch between systems. The current version for the MetaBrowser was designed for the DOE CEDR (Comprehensive Epidemiological Data Resource) project, but the same principles can apply to other scientific disciplines. Browsing and query should be combined. It is quite natural for a user to explore the information in the database before deciding what subset of the data to select for further analysis. In general, if there is a large number of datasets (i.e. databases) in the system, then the user would want to find out information about the various datasets (called metadata), before choosing one or more datasets for further exploration. Thus, a metadatabase that holds information about datasets in the systems must exist.

Query on Negative Temperature, Internal Interactions and Decrease of Entropy  

E-Print Network (OSTI)

After negative temperature is restated, we find that it will derive necessarily decrease of entropy. Negative temperature is based on the Kelvin scale and the condition dU>0 and dS0. But, negative temperature is contradiction with usual meaning of temperature and with some basic concepts of physics and mathematics. It is a question in nonequilibrium thermodynamics. We proposed a possibility of decrease of entropy due to fluctuation magnified and internal interactions in some isolated systems. From this we discuss some possible examples and theories.

Multi-query SQL progress indicators  

E-Print Network (OSTI)

Abstract. Recently, progress indicators have been proposed for SQL queries in RDBMSs. All previously proposed progress indicators consider each query in isolation, ignoring the impact simultaneously running queries have on each other’s performance. In this paper, we explore a multi-query progress indicator, which explicitly considers concurrently running queries and even queries predicted to arrive in the future when producing its estimates. We demonstrate that multi-query progress indicators can provide more accurate estimates than single-query progress indicators. Moreover, we extend the use of progress indicators beyond being a GUI tool and show how to apply multi-query progress indicators to workload management. We report on an initial implementation of a multi-query progress indicator in PostgreSQL and experiments with its use both for estimating remaining query execution time and for workload management. 1

Interactive Analysis of Large Network Data Collections UsingQuery-Driven Visualization  

Science Conference Proceedings (OSTI)

Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. Considering the extreme scale of contemporary datasets, one significant challenge is to reduce the duty cycle in the analytics discourse process. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysis technologies targeted at reducing the duty cyclein hypothesis testing and knowledge discovery. We present an application of such a combination in the problem domain of network traffic data analysis. Our performance experiment results, including both serial and parallel scalability tests, show that the combination can dramatically decrease the analytics duty cycle for this particular application. The combination is effectively applied to the analysis of network traffic data to detect slow and distributed scans, which is a difficult-to-detect form of cyber attack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools.

Tools and Equipment Modeling for Automobile Interactive Assembling Operating Simulation  

SciTech Connect

Tools and equipment play an important role in the simulation of virtual assembly, especially in the assembly process simulation and plan. Because of variety in function and complexity in structure and manipulation, the simulation of tools and equipments remains to be a challenge for interactive assembly operation. Based on analysis of details and characteristics of interactive operations for automobile assembly, the functional requirement for tools and equipments of automobile assembly is given. Then, a unified modeling method for information expression and function realization of general tools and equipments is represented, and the handling methods of manual, semi-automatic, automatic tools and equipments are discussed. Finally, the application in assembly simulation of rear suspension and front suspension of Roewe 750 automobile is given. The result shows that the modeling and handling methods are applicable in the interactive simulation of various tools and equipments, and can also be used for supporting assembly process planning in virtual environment.

Interactive graphical tools for three-dimensional mesh redistribution  

Science Conference Proceedings (OSTI)

Three-dimensional meshes modeling nonlinear problems such as sheet metal forming, metal forging, heat transfer during welding, the propagation of microwaves through gases, and automobile crashes require highly refined meshes in local areas to accurately represent areas of high curvature, stress, and strain. These locally refined areas develop late in the simulation and/or move during the course of the simulation, thus making it difficult to predict their exact location. This thesis is a systematic study of new tools scientists can use with redistribution algorithms to enhance the solution results and reduce the time to build, solve, and analyze nonlinear finite element problems. Participatory design techniques including Contextual Inquiry and Design were used to study and analyze the process of solving such problems. This study and analysis led to the in-depth understanding of the types of interactions performed by FEM scientists. Based on this understanding, a prototype tool was designed to support these interactions. Scientists participated in evaluating the design as well as the implementation of the prototype tool. The study, analysis, prototype tool design, and the results of the evaluation of the prototype tool are described in this thesis.

Parallel Index and Query for Large Scale Data Analysis  

SciTech Connect

Modern scientific datasets present numerous data management and analysis challenges. State-of-the-art index and query technologies are critical for facilitating interactive exploration of large datasets, but numerous challenges remain in terms of designing a system for process- ing general scientific datasets. The system needs to be able to run on distributed multi-core platforms, efficiently utilize underlying I/O infrastructure, and scale to massive datasets. We present FastQuery, a novel software framework that address these challenges. FastQuery utilizes a state-of-the-art index and query technology (FastBit) and is designed to process mas- sive datasets on modern supercomputing platforms. We apply FastQuery to processing of a massive 50TB dataset generated by a large scale accelerator modeling code. We demonstrate the scalability of the tool to 11,520 cores. Motivated by the scientific need to search for inter- esting particles in this dataset, we use our framework to reduce search time from hours to tens of seconds.

Geomodification in query rewriting  

E-Print Network (OSTI)

Web searchers signal their geographic intent by using placenames in search queries. They also indicate their flexibility about geographic specificity by reformulating their queries. We conducted experiments on geomodification in query rewriting. We examine both deliberate query rewriting, conducted in user search sessions, and automated query rewriting, with users evaluating the relevance of geo-modified queries. We find geo-specification in 12.7 % of user query rewrites in search sessions, and show the breakdown into sub-classes such as same-city, same-state, same-country and different-country. We also measure the dependence between US-state-name and distance-of-modified-location-from-originallocation, finding that Vermont web searchers modify their locations greater distances than California web searchers. We also find that automatically-modified queries are perceived as much more relevant when the geographic component is unchanged.

Accelerating Network Traffic Analytics Using Query-DrivenVisualization  

SciTech Connect

Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysis technologies targeted at reducing the time required for data filtering, querying, hypothesis testing and knowledge discovery in the domain of network connection data analysis. We show that use of compressed bitmap indexing can quickly answer queries in an interactive visual data analysis application, and compare its performance with two alternatives for serial and parallel filtering/querying on 2.5 billion records worth of network connection data collected over a period of 42 weeks. Our approach to visual network connection data exploration centers on two primary factors: interactive ad-hoc and multiresolution query formulation and execution over n dimensions and visual display of then-dimensional histogram results. This combination is applied in a case study to detect a distributed network scan and to then identify the set of remote hosts participating in the attack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools.

Interactive image quantification tools in nuclear material forensics  

Science Conference Proceedings (OSTI)

Morphological and microstructural features visible in microscopy images of nuclear materials can give information about the processing history of a nuclear material. Extraction of these attributes currently requires a subject matter expert in both microscopy and nuclear material production processes, and is a time consuming, and at least partially manual task, often involving multiple software applications. One of the primary goals of computer vision is to find ways to extract and encode domain knowledge associated with imagery so that parts of this process can be automated. In this paper we describe a user-in-the-loop approach to the problem which attempts to both improve the efficiency of domain experts during image quantification as well as capture their domain knowledge over time. This is accomplished through a sophisticated user-monitoring system that accumulates user-computer interactions as users exploit their imagery. We provide a detailed discussion of the interactive feature extraction and segmentation tools we have developed and describe our initial results in exploiting the recorded user-computer interactions to improve user productivity over time.

Visionary: a viewpoint-based visual language for querying relational databases  

E-Print Network (OSTI)

The adoption of a visual interface can simplify the query formulation process in DBMSs by enabling naive users to interact with a friendly environment. In this work we propose a visual query language based on a diagrammatic paradigm, used for both data and query representation. The external data model is called vision and is made up of the visual primitives of concept and association. The external query model is based on the definition of a viewpoint, which is a perspective for accessing data defined dynamically by selecting a concept of primary interest. Internally, the data model is relational and the query language is SQL. An intermediate graph-based model ensures consistent mapping between the visual and the relational worlds. Our language has been implemented within a tool which can be mounted on top of any relational DBMS supporting ODBC. The system has been tested with naive users; the results of the experiment are reported and compared with those obtained with other visual languages. Keywords and phrases: VPL-II.B.1: Diagrammatic languages, VPL-V.B: Database languages 1

QueryLines: approximate query for visual browsing  

E-Print Network (OSTI)

We introduce approximate query techniques for searching and analyzing two-dimensional data sets such as line or scatter plots. Our techniques allow users to explore a dataset by defining QueryLines: soft constraints and preferences for selecting and sorting a subset of the data. By using both preferences and soft constraints for query composition, we allow greater flexibility and expressiveness than previous visual query systems. When the user over-constrains a query, for example, a system using approximate techniques can display ¨near misses¨to enable users to quickly and continuously refine queries.

Evaluating verbose query processing techniques  

E-Print Network (OSTI)

Verbose or long queries are a small but significant part of the query stream in web search, and are common in other applications such as collaborative question answering (CQA). Current search engines perform well with keyword queries but are not, in general, effective for verbose queries. In this paper, we examine query processing techniques which can be applied to verbose queries prior to submission to a search engine in order to improve the search engine’s results. We focus on verbose queries that have sentence-like structure, but are not simple “wh- ” questions, and assume the search engine is a “black box. ” We evaluated the output of two search engines using queries from a CQA service and our results show that, among a broad range of techniques, the most effective approach is to simply reduce the length of the query. This can be achieved effectively by removing “stop structure ” instead of only stop words. We show that the process of learning and removing stop structure from a query can be effectively automated.

Querying for Feature Extraction and Visualization in Climate Modeling  

SciTech Connect

The ultimate goal of data visualization is to clearly portray features relevant to the problem being studied. This goal can be realized only if users can effectively communicate to the visualization software what features are of interest. To this end, we describe in this paper two query languages used by scientists to locate and visually emphasize relevant data in both space and time. These languages offer descriptive feedback and interactive refinement of query parameters, which are essential in any framework supporting queries of arbitrary complexity. We apply these languages to extract features of interest from climate model results and describe how they support rapid feature extraction from large datasets.

Online query answering with differential privacy: a utility-driven approach using Bayesian inference  

E-Print Network (OSTI)

Data privacy issues frequently and increasingly arise for data sharing and data analysis tasks. In this paper, we study the problem of online query answering under the rigorous differential privacy model. The existing interactive mechanisms for differential privacy can only support a limited number of queries before the accumulated cost of privacy reaches a certain bound. This limitation has greatly hindered their applicability, especially in the scenario where multiple users legitimately need to pose a large number of queries. To minimize the privacy cost and extend the life span of a system, we propose a utility-driven mechanism for online query answering using Bayesian statistical inference. The key idea is to keep track of the query history and use Bayesian inference to answer a new query using previous query answers. The Bayesian inference algorithm provides both optimal point estimation and optimal interval estimation. We formally quantify the error of the inference result to determine if it satisfies t...

Small-molecule tools for dissecting the roles of SSB/protein interactions in genome maintenance  

SciTech Connect

Bacterial single-stranded DNA-binding proteins (SSBs) help to recruit a diverse array of genome maintenance enzymes to their sites of action through direct protein interactions. For all cases examined to date, these interactions are mediated by the evolutionarily conserved C terminus of SSB (SSB-Ct). The essential nature of SSB protein interactions makes inhibitors that block SSB complex formation valuable biochemical tools and attractive potential antibacterial agents. Here, we identify four small molecules that disrupt complexes formed between Escherichia coli SSB and Exonuclease I (ExoI), a well-studied SSB-interacting enzyme. Each compound disrupts ExoI/SSB-Ct peptide complexes and abrogates SSB stimulation of ExoI nuclease activity. Structural and biochemical studies support a model for three of the compounds in which they compete with SSB for binding to ExoI. The fourth appears to rely on an allosteric mechanism to disrupt ExoI/SSB complexes. Subsets of the inhibitors block SSB-Ct complex formation with two other SSB-interaction partners as well, which highlights their utility as reagents for investigating the roles of SSB/protein interactions in diverse DNA replication, recombination, and repair reactions.

VISIONARY: a visual query language based on the user viewpoint approach  

E-Print Network (OSTI)

Query languages for RDBMSs lack in intuitive understanding; this precludes inexperienced users from taking advantage of them. The adoption of a visual interface can simplify the query formulation process by enabling users to interact with a friendly environment. In this work we propose a visual query language based on a hybrid iconic-diagrammatic paradigm, used for both data and query representation. The external data model is called vision and comprises the visual primitives of concept- represented by the combination of text and icon, and association- represented by a name and a multiplicity for each possible orientation. The external query model is based on the definition of a user viewpoint, which is a perspective for accessing data defined dynamically by selecting a concept of primary interest for formulating each query. 1

Quantum query complexity for qutrits  

Science Conference Proceedings (OSTI)

We compute lower bounds for the exact quantum query complexity of a ternary function f. The lower bound is of order O(log{sub 3}(n)). In case f is symmetric on a sphere then the lower bound is of order O({radical}(n)). This work is a natural continuation of the work of Beals, Buhrman, Cleve, Mosca, and de Wolf on lower limits for binary functions.

Structured Query Language for Virtual Observatory  

E-Print Network (OSTI)

Currently two query languages are defined as standards for the Virtual Observatory (VO). Astronomical Data Query Language (ADQL) is used for catalog data query and Simple Image Access Protocol (SIAP) is for image data query. As a result, when we query each data service, we need to know in advance which language is supported and then construct a query language accordingly. The construct of SIAP is simple, but they have a limited capability. For example, there is no way to specify multiple regions in one query, and it is difficult to specify complex query conditions. In this paper, we propose a unified query language for any kind of astronomical database on the basis of SQL99. SQL is a query language optimized for a table data, so to apply the SQL to the image and spectrum data set, the data structure need to be mapped to a table like structure. We present specification of this query language and an example of the architecture for the database system.

Context-Sensitive Query Auto-Completion ?  

E-Print Network (OSTI)

Query auto completion is known to provide poor predictions of the user’s query when her input prefix is very short (e.g., one or two characters). In this paper we show that context, such as the user’s recent queries, can be used to improve the prediction quality considerably even for such short prefixes. We propose a context-sensitive query auto completion algorithm, NearestCompletion, which outputs the completions of the user’s input that are most similar to the context queries. To measure similarity, we represent queries and contexts as high-dimensional term-weighted vectors and resort to cosine similarity. The mapping from queries to vectors is done through a new query expansion technique that we introduce, which expands a query by traversing the query recommendation tree rooted at the query. In order to evaluate our approach, we performed extensive experimentation over the public AOL query log. We demonstrate that when the recent user’s queries are relevant to the current query she is typing, then after typing a single character, NearestCompletion’s MRR is 48 % higher relative to the MRR of the standard MostPopularCompletion algorithm on average. When the context is irrelevant, however, NearestCompletion’s MRR is essentially zero. To mitigate this problem, we propose HybridCompletion, which is a hybrid of NearestCompletion with MostPopularCompletion. HybridCompletion is shown to dominate both NearestCompletion and MostPopularCompletion, achieving a total improvement of 31.5 % in MRR relative to MostPopular-Completion on average.

Integrating implicit answers with object-oriented queries  

E-Print Network (OSTI)

Queries in object-oriented datab;Lqcs are formulated against a class and retrieve instnnccls of the class sat,is-fying a certain predicate on the att,riblltes of the class. The presence of a class hierarchy, an integral part of any object-oriented data model, allows answers to be expressed implicitly in terms of classes and instances. This enables answers to be provided at different levels of abstraction. Shum and Muntz [SM88] presented a way of providing implicit expressions based on a taxonomy defined over the database. The algorithm presented in [SM88] is optimal in the length of the answer but the clarity of the answer is often poor. In this paper, the fo-cus is on coherent answers: implicit answers that are not necessarily optimal in the number of terms but are easy to comprehend. We show that a uniqlle coherent answer can be obtained efficiently in a top down nlanncr. Since the objective is to provide cohcrcnt, answers, and user queries are formulated by means of query operators to access the database, the standard query operators are redefined to obtain and manipulate coherent answers. Coherent answers are useful in coping with information complexity as they allow answers to be represented ab-stractly and are also a useful rctprescntation tool for complex information systems. 1

Qunits: queried units in database search  

E-Print Network (OSTI)

Keyword search against structured databases has become a popular topic of investigation, since many users find structured queries too hard to express, and enjoy the freedom of a ``Google-like'' query box into which search terms can be entered. Attempts to address this problem face a fundamental dilemma. Database querying is based on the logic of predicate evaluation, with a precisely defined answer set for a given query. On the other hand, in an information retrieval approach, ranked query results have long been accepted as far superior to results based on boolean query evaluation. As a consequence, when keyword queries are attempted against databases, relatively ad-hoc ranking mechanisms are invented (if ranking is used at all), and there is little leverage from the large body of IR literature regarding how to rank query results. Our proposal is to create a clear separation between ranking and database querying. This divides the problem into two parts, and allows us to address these separately. The first tas...

Design of FastQuery: How to Generalize Indexing and Querying System for Scientific Data  

Science Conference Proceedings (OSTI)

Modern scientific datasets present numerous data management and analysis challenges. State-of-the-art index and query technologies such as FastBit are critical for facilitating interactive exploration of large datasets. These technologies rely on adding auxiliary information to existing datasets to accelerate query processing. To use these indices, we need to match the relational data model used by the indexing systems with the array data model used by most scientific data, and to provide an efficient input and output layer for reading and writing the indices. In this work, we present a flexible design that can be easily applied to most scientific data formats. We demonstrate this flexibility by applying it to two of the most commonly used scientific data formats, HDF5 and NetCDF. We present two case studies using simulation data from the particle accelerator and climate simulation communities. To demonstrate the effectiveness of the new design, we also present a detailed performance study using both synthetic and real scientific workloads.

Building an Efficient Preference XML Query Processor  

E-Print Network (OSTI)

Today user-centered information acquisition over collections of complex XML documents is increasingly in demand. To this end, preferences have become an important paradigm enabling users to express individual interests and delivering personalized information. As the structure of XML documents plays a major part in retrieval, users often have specific preferences about the structure. For evaluation a query has to be unfolded into an entire set of queries filling the structure with more or less preferred values. Since such structure expansions typically contain redundancies, it is important to identify and simplify necessary expansion queries for effective evaluation. To address these issues, we developed a preference query optimizer that not only determines an optimal set of expansion queries, but also preserves the specific ordering induced by the user preferences with respect to Pareto optimality.

Query Selectivity Estimation for Uncertain Data  

E-Print Network (OSTI)

Abstract. Applications requiring the handling of uncertain data have led to the development of database management systems extending the scope of relational databases to include uncertain (probabilistic) data as a native data type. New automatic query optimizations having the ability to estimate the cost of execution of a given query plan, as available in existing databases, need to be developed. For probabilistic data this involves providing selectivity estimations that can handle multiple values for each attribute and also new query types with threshold values. This paper presents novel selectivity estimation functions for uncertain data and shows how these functions can be integrated into PostgreSQL to achieve query optimization for probabilistic queries over uncertain data. The proposed methods are able to handle both attribute- and tuple-uncertainty. Our experimental results show that our algorithms are efficient and give good selectivity estimates with low space-time overhead. 1

Experimental quantum private queries with linear optics  

Science Conference Proceedings (OSTI)

The quantum private query is a quantum cryptographic protocol to recover information from a database, preserving both user and data privacy: the user can test whether someone has retained information on which query was asked and the database provider can test the amount of information released. Here we discuss a variant of the quantum private query algorithm that admits a simple linear optical implementation: it employs the photon's momentum (or time slot) as address qubits and its polarization as bus qubit. A proof-of-principle experimental realization is implemented.

Querying Incomplete Data over Extended ER Schemata  

E-Print Network (OSTI)

Since Chen's Entity-Relationship (ER) model, conceptual modeling has been playing a fundamental role in relational data design. In this paper we consider an extended ER (EER) model enriched with cardinality constraints, disjointness assertions, and is-a relations among both entities and relationships. In this setting, we consider the case of incomplete data, which is likely to occur, for instance, when data from different sources are integrated. In such a context, we address the problem of providing correct answers to conjunctive queries by reasoning on the schema. Based on previous results about decidability of the problem, we provide a query answering algorithm that performs rewriting of the initial query into a recursive Datalog query encoding the information about the schema. We finally show extensions to more general settings.

Graph pattern queries are an important feature of a graph query language. Translating graph pattern queries into single SQL statements results in very poor query performance. By taking into account the pattern query structure and generating multiple SQL statements, pattern query performance can be dramatically improved. The performance problems encountered with the single SQL statements generated for pattern queries reflects a problem in the SQL query planner and optimizer. Addressing this problem would allow relational databases to better support semantic graph databases. Relational database systems that provide good support for graph databases may also be more flexible platforms for data warehouses.

Interactive tools designed to study mix in inertial confinement fusion implosions  

SciTech Connect

Graphical user interface tools have been built in IDL to study mix in inertial confinement fusion (ICF) implosion cores. FLAME (Fall-Line Analysis Mix Evaluator), a code which investigates yield degradation due to mix , was designed to post-process 1D hydrodynamic simulation output by implementing a variety of mix models. Three of these mix models are based on the physics of the fall-line. In addition, mixing data from other sources can be incorporated into the yield degradation analysis. Two independent tools called HAME (Haan Analysis Mix Evaluator) and YAME (Youngs Analysis Mix Evaluator) were developed to calculate the spatial extent of the mix region according to the Haan saturation model and Youngs' phenomenological model, respectively. FLAME facilitates a direct comparison to experimental data. The FLAME, HAME, and YAME interfaces are user-friendly, flexible, and platform-independent.

The Framework for Approximate Queries on Simulation Data  

SciTech Connect

AQSim is a system intended to enable scientists to query and analyze a large volume of scientific simulation data. The system uses the state of the art in approximate query processing techniques to build a novel framework for progressive data analysis. These techniques are used to define a multi-resolution index, where each node contains multiple models of the data. The benefits of these models are two-fold: (1) they are compact representations, reconstructing only the information relevant to the analysis, and (2) the variety of models capture different aspects of the data which may be of interest to the user but are not readily apparent in their raw form. To be able to deal with the data interactively, AQSim allows the scientist to make an informed tradeoff between query response accuracy and time. In this paper, we present the framework of AQSim with a focus on its architectural design. We also show the results from an initial proof-of-concept prototype developed at LLNL. The presented framework is generic enough to handle more than just simulation data.

Inferring Function Semantics to Optimize Queries  

E-Print Network (OSTI)

The goal of the COKO-KOLA project [10, 9] is to express rules of rule-based optimizers in a manner permitting verification with a theorem prover. In [10], we considered query transformations that were too general to be expressed with rewrite rules. In this paper, we consider the complementary issue of expressing query transformations that are too specifc for rewrite rules. Such transformations require rewrite rules to be supplemented with semantic conditions to guard rule firing. This work considers the expression of such transformations using conditional rewrite rules, and the expression of inference rules to guide the optimizer in deciding if semantic conditions hold. This work differs from existing work in semantic query optimization in that semantic transformations in our framework are verifiable with a theorem prover. Further, our use of inference rules to guide semantic reasoning makes our optimizer extensible in a manner that is complementary to the extensibility benefits of existing rule-based technology. 1

Data management tools for genomic applications: A progress report  

SciTech Connect

We report in this paper on the development of data management tools that allow scientist to construct and manipulate genomic data bases in terms of application-specific objects and protocols. We are developing tools for specifying genomic database structures, as well as for entering, changing, maintaining, browsing and querying data in genomic data bases. These tools are based on the Object-protocol Model (OPM) developed by us and target commercial relational database management systems which are widely used in molecular biology laboratories. OPM allows scientists to interact with genomic databases in terms of their own frame or reference, namely genomic objects and protocols. Databases developed using the data management tools are easier to use, manage, and adapt.

V.: GLOO: A Graphical Query Language for OWL Ontologies. OWLED  

E-Print Network (OSTI)

Abstract. The database usability experience has shown that visual query languages tend to be superior to textual languages in many aspects. By applying this principle in the context of ontologies, we present GLOO, a graphical query language for OWL-DL ontologies. GLOO maps diagrammatic queries to DL based query languages such as nRQL, which is offered by the OWL-DL reasoner Racer. GLOO hides the complexity of a DL query language from users and allows them to query OWL ontologies with less difficulty. 1

Quantum query complexity of some graph problems  

E-Print Network (OSTI)

Quantum algorithms for graph problems are considered, both in the adjacency matrix model and in an adjacency list-like array model. We give almost tight lower and upper bounds for the bounded error quantum query complexity of Connectivity, Strong Connectivity, Minimum Spanning Tree, and Single Source Shortest Paths. For example we show that the query complexity of Minimum Spanning Tree is in Theta(n^{3/2}) in the matrix model and in Theta(sqrt{nm}) in the array model, while the complexity of Connectivity is also in Theta(n^{3/2}) in the matrix model, but in Theta(n) in the array model. The upper bounds utilize search procedures for finding minima of functions under various conditions.

An Application of Multivariate Statistical Analysis for Query-Driven Visualization  

Science Conference Proceedings (OSTI)

Abstract?Driven by the ability to generate ever-larger, increasingly complex data, there is an urgent need in the scientific community for scalable analysis methods that can rapidly identify salient trends in scientific data. Query-Driven Visualization (QDV) strategies are among the small subset of techniques that can address both large and highly complex datasets. This paper extends the utility of QDV strategies with a statistics-based framework that integrates non-parametric distribution estimation techniques with a new segmentation strategy to visually identify statistically significant trends and features within the solution space of a query. In this framework, query distribution estimates help users to interactively explore their query's solution and visually identify the regions where the combined behavior of constrained variables is most important, statistically, to their inquiry. Our new segmentation strategy extends the distribution estimation analysis by visually conveying the individual importance of each variable to these regions of high statistical significance. We demonstrate the analysis benefits these two strategies provide and show how they may be used to facilitate the refinement of constraints over variables expressed in a user's query. We apply our method to datasets from two different scientific domains to demonstrate its broad applicability.

An Improved Query for the Hidden Subgroup Problem  

E-Print Network (OSTI)

An equal superposition query with |0> in the response register is used in the "standard method" of single-query algorithms for the hidden subgroup problem (HSP). Here we introduce a different query, the character query, generalizing the well-known phase kickback trick. This query maximizes the success probability of subgroup identification under a uniform prior, for the HSP in which the oracle functions take values in a finite abelian group. We then apply our results to the case when the subgroups are drawn from a set of conjugate subgroups and obtain a success probability greater than that found by Moore and Russell.

Automatic discovery of query-classdependent models for multimodal search  

E-Print Network (OSTI)

We develop a framework for the automatic discovery of query classes for query-class-dependent search models in multimodal retrieval. The framework automatically discovers useful query classes by clustering queries in a training set according to the performance of various unimodal search methods, yielding classes of queries which have similar fusion strategies for the combination of unimodal components for multimodal search. We further combine these performance features with the semantic features of the queries during clustering in order to make discovered classes meaningful. The inclusion of the semantic space also makes it possible to choose the correct class for new, unseen queries, which have unknown performance space features. We evaluate the system against the TRECVID 2004 automatic video search task and find that the automatically discovered query classes give an improvement of 18% in MAP over hand-defined query classes used in previous works. We also find that some hand-defined query classes, such as “Named Person ” and “Sports ” do, indeed, have similarities in search method performance and are useful for query-class-dependent multimodal search, while other hand-defined classes, such as “Named Object” and “General Object” do not have consistent search method performance and should be split apart or replaced with other classes. The proposed framework is general and can be applied to any new domain without expert domain knowledge.

A Hybrid Query Language for an Extended Entity-Relationship Model  

E-Print Network (OSTI)

We present the hybrid query language HQL/EER for an Extended Entity-Relationship model. As its main characteristic, this language allows a user to use both graphical and textual elements in the formulation of one and the same query. We demonstrate the lookand -feel of this query language by means of examples, and show how syntax and semantics of this language are formally defined using programmed graph rewriting systems. Although we present the language in the context of the EER model, the concept of hybrid languages is applicable in the context of other database models as well. We illustrate this claim by discussing a prototype implementation of a Hybrid Query Tool based on an object-oriented approach, namely the Object Modeling Technique (OMT). 1 Introduction The database research efforts of the past decade have provided us with a wide range of both database models and systems, allowing the user to perform complex manipulations on data structures of high modeling power.

Intentional query suggestion: making user goals more explicit during search  

E-Print Network (OSTI)

student.tugraz.at The degree to which users ’ make their search intent explicit can be assumed to represent an upper bound on the level of service that search engines can provide. In a departure from traditional query expansion mechanisms, we introduce Intentional Query Suggestion as a novel idea that is attempting to make users ’ intent more explicit during search. In this paper, we present a prototypical algorithm for Intentional Query Suggestion and we discuss corresponding data from comparative experiments with traditional query suggestion mechanisms. Our preliminary results indicate that intentional query suggestions 1) diversify search result sets (i.e. it reduces result set overlap) and 2) have the potential to yield higher click-through rates than traditional query suggestions.

Inferring query performance using pre-retrieval predictors  

E-Print Network (OSTI)

Abstract. The prediction of query performance is an interesting and important issue in Information Retrieval (IR). Current predictors involve the use of relevance scores, which are time-consuming to compute. Therefore, current predictors are not very suitable for practical applications. In this paper, we study a set of predictors of query performance, which can be generated prior to the retrieval process. The linear and non-parametric correlations of the predictors with query performance are thoroughly assessed on the TREC disk4 and disk5 (minus CR) collections. According to the results, some of the proposed predictors have significant correlation with query performance, showing that these predictors can be useful to infer query performance in practical applications. 1

Web Service Composition Through Declarative Queries: The Case of Conjunctive Queries with Union and Negation  

E-Print Network (OSTI)

A web service operation can be seen as a function op: X1,...,Xn ? Y1,...,Ym having an input message (request) with n arguments (parts), and an output message (response) with m parts [4, Section 2.2]. For example, opB: Author ?{(ISBN, Title)} may implement a books search service, returning for a given author A a list of books authored by A. We propose to model such operations as relations with access pattern, here: B oio (ISBN, Author, Title), where ‘oio ’ indicates that a value for the second attribute must be given as input, while the other attribute values can be retrieved as output. In this way, a family of web service operations over k attributes can be concisely described as a relation R(A1,...,Ak) with an associated set of access patterns P?{i, o} k. Since we model web services as relations with access patterns, we can now use queries as a declarative specifications for web service composition: e.g., the query Q(I, A, T) ? ? B(I, A, T),C(I,A), ¬L(I) asks for books available through a store B which are contained in a catalog C, but not in the local library L. Let the only access patterns be B ioo, B oio, C oo, and L o. If we try to execute Q from left to right, neither pattern for B works since we either lack an ISBN I or an author A. However, Q is feasible since we can execute it by first calling C(I,A) which binds both I and A; after that, calling B ioo (or B oio) will work. Calling ¬L(I) first and then B does not work: a negated call can only filter out answers, but cannot produce any new variable bindings. 2. Formal Results We study the problem of deciding whether a query Q is feasible, i.e., whether there exists a logically equivalent query Q ? that can be executed observing the limited access patterns given by the web service (source) relations. Executability depends on the specific syntactic form of a query, while feasibility is a more “robust ” semantic notion, in-

Information Retrieval manuscript No. (will be inserted by the editor) When Do People Use Query Suggestion? A Query Suggestion Log Analysis  

E-Print Network (OSTI)

(Authors ’ version. The final publication is available at www.springerlink.com.) Abstract Query suggestion, which enables the user to revise a query with a single click, has become one of the most fundamental features of Web search engines. However, it has not been clear what circumstances cause the user to turn to query suggestion. In order to investigate when and how the user uses query suggestion, we analyzed three kinds of data sets obtained from a major commercial Web search engine, comprising approximately 126 million unique queries, 876 million query suggestions and 306 million action patterns of users. Our analysis shows that query suggestions are often used (1) when the original query is a rare query; (2) when the original query is a single-term query; (3) when query suggestions are unambiguous; (4) when query suggestions are generalizations or error corrections of the original query; and (5) after the user has clicked on several URLs in the first search result page. Our results suggest that search engines should provide better assistance especially when rare or single-term queries are input, and that they should dynamically provide query suggestions according to the searcher’s current state.

Hourly analysis of a very large topically categorized web query log  

E-Print Network (OSTI)

We review a query log of hundreds of millions of queries that constitute the total query traffic for an entire week of a generalpurpose commercial web search service. Previously, query logs have been studied from a single, cumulative view. In contrast, our analysis shows changes in popularity and uniqueness of topically categorized queries across the hours of the day. We examine query traffic on an hourly basis by matching it against lists of queries that have been topically pre-categorized by human editors. This represents 13 % of the query traffic. We show that query traffic from particular topical categories differs both from the query stream as a whole and from other categories. This analysis provides valuable insight for improving retrieval effectiveness and efficiency. It is also relevant to the development of enhanced query disambiguation, routing, and caching algorithms.

DOE Green Energy (OSTI)

QUERY is a computer program used for the retrieval of environmental data. The code was developed in support of the Imperial Valley Environmental Project of the Environmental Sciences division at Lawrence Livermore Laboratory to handle a multitude of environmentally related information. The program can run in either an interactive mode or production mode to retrieve these data. In either case, the user specifies a set of search constraints and then proceeds to select an output format from a menu of output options or to specify the output format according to his immediate needs. Basic data statistics can be requested. Merging of disparate data bases and subfile extraction are elementary.

On concurrency control in sliding window queries over data streams  

E-Print Network (OSTI)

Work done while the author was visiting the University of Waterloo. Data stream systems execute a dynamic workload of long-running and one-time queries, with the streaming inputs typically bounded by sliding windows. For efficiency, windows may be advanced periodically by replacing the oldest part of the window with a batch of newly arrived data. Existing work on stream processing assumes that a window cannot be advanced while it is being accessed by a query. In this paper, we argue that concurrent processing of queries (reads) and window-slides (writes) is required by data stream systems in order to allow prioritized query scheduling and improve the freshness of answers. We prove that the traditional notion of conflict serializability is insufficient in this context and define stronger isolation levels that restrict the allowed serialization orders. We also design and experimentally evaluate a transaction scheduler that efficiently enforces the new isolation levels by taking advantage of the access patterns of sliding window queries. 1

Effective Graph Clustering for Path Queries in Digital Map Databases  

E-Print Network (OSTI)

In this paper, we present an experimental evaluation of graph clustering strategies in terms of their effectiveness in optimizing I/O for path query processing in digital map databases. Clustering optimization is attractive because it does not incurs any run-time cost, and is complimentary to many of the existing techniques in path query optimization. We first propose a novel graph clustering technique, called Spatial Partition Clustering (SPC), that creates balanced partitions of links based on the spatial proximity of their origin nodes. We then select three alternative clustering techniques from the literature, namely two-way partitioning, approximately topological clustering, and random clustering, to compare their performance in path query processing with SPC. Experimental evaluation indicates that our SPC performs the best for the high-locality graphs (such as GIS maps), whereas the two-way partitioning approach performs the best for no-locality random graphs. 1 Introduction 1....

Optimal query/update tradeoffs in versioned dictionaries  

E-Print Network (OSTI)

External-memory dictionaries are a fundamental data structure in file systems and databases. Versioned (or fully-persistent) dictionaries have an associated version tree where queries can be performed at any version, updates can be performed on leaf versions, and any version can be `cloned' by adding a child. Various query/update tradeoffs are known for unversioned dictionaries, many of them with matching upper and lower bounds. No fully-versioned external-memory dictionaries are known with optimal space/query/update tradeoffs. In particular, no versioned constructions are known that offer updates in $o(1)$ I/Os using O(N) space. We present the first cache-oblivious and cache-aware constructions that achieve a wide range of optimal points on this tradeoff.

Monte Carlo tools for studies of non-standard electroweak gauge boson interactions in multi-boson processes: A Snowmass White Paper  

E-Print Network (OSTI)

In this Snowmass 2013 white paper, we review the effective field theory approach for studies of non-standard electroweak interactions in electroweak vector boson pair and triple production and vector boson scattering. We present an overview of the implementation of dimension six and eight operators in MadGraph5, VBFNLO, and WHIZARD, and provide relations between the coefficients of these higher dimensions operators used in these programs and in the anomalous couplings approach. We perform a tuned comparison of predictions for multi-boson processes including non-standard electroweak interactions with MadGraph5, VBFNLO, and WHIZARD. We discuss the role of higher-order corrections in these predictions using VBFNLO and a POWHEG BOX implementation of higher-order QCD corrections to WWjj production. The purpose of this white paper is to collect useful tools for the study of non-standard EW physics at the LHC, compare them, and study the main physics issues in the relevant processes.

Secure quantum private information retrieval using phase-encoded queries  

Science Conference Proceedings (OSTI)

We propose a quantum solution to the classical private information retrieval (PIR) problem, which allows one to query a database in a private manner. The protocol offers privacy thresholds and allows the user to obtain information from a database in a way that offers the potential adversary, in this model the database owner, no possibility of deterministically establishing the query contents. This protocol may also be viewed as a solution to the symmetrically private information retrieval problem in that it can offer database security (inability for a querying user to steal its contents). Compared to classical solutions, the protocol offers substantial improvement in terms of communication complexity. In comparison with the recent quantum private queries [Phys. Rev. Lett. 100, 230502 (2008)] protocol, it is more efficient in terms of communication complexity and the number of rounds, while offering a clear privacy parameter. We discuss the security of the protocol and analyze its strengths and conclude that using this technique makes it challenging to obtain the unconditional (in the information-theoretic sense) privacy degree; nevertheless, in addition to being simple, the protocol still offers a privacy level. The oracle used in the protocol is inspired both by the classical computational PIR solutions as well as the Deutsch-Jozsa oracle.

FastBit: Interactively Searching Massive Data  

Science Conference Proceedings (OSTI)

As scientific instruments and computer simulations produce more and more data, the task of locating the essential information to gain insight becomes increasingly difficult. FastBit is an efficient software tool to address this challenge. In this article, we present a summary of the key underlying technologies, namely bitmap compression, encoding, and binning. Together these techniques enable FastBit to answer structured (SQL) queries orders of magnitude faster than popular database systems. To illustrate how FastBit is used in applications, we present three examples involving a high-energy physics experiment, a combustion simulation, and an accelerator simulation. In each case, FastBit significantly reduces the response time and enables interactive exploration on terabytes of data.

Case tool evaluation system  

SciTech Connect

An automated system that uses an analytical approach to evaluate Computer-Aided Software Engineering (CASE) tools is currently being developed. this system is referred to as the CASE Tool Evaluation System. The following general criteria will be used: overall tool functionality; tool stability; cost; interfaces with other software; customization; ease of use; output produced; hardware and operating system needs; documentation; training and vendor support; repository interface; methodologies; and vendor stability. in Phase 1 CASE tools will be eliminated that do not meet certain must-have'' characteristics specified by the user. Phase 2 will further reduce the size of the tool list by retaining those tools that possess desirable, but not absolutely necessary'' characteristics, also specified by the user. Phase 3 will employ the Analytic Hierarchy Process, developed by Dr. Thomas L. Saaty, to rank the tools. Users will be able to supply tools of their own choosing, in addition to tools that are generated via normal use of the system. All three phases will interact with a database that stores objective information about CASE tools. The use of the Analytic Hierarchy process (AHP) distinguishes this method of CASE tool evaluation from others. As used in this system, the AHP is a method of breaking down the complex, unstructured problem of selecting a CASE tool into its component evaluation criteria and candidate tools. These criteria and tools are arranged into a hierarchical order. Each criterion and tool is assigned a subjective numerical value (by experts or users or both). These values are then synthesized to determine which have the highest priority. The result will be a ranked list of CASE tools tailored to the needs and desires of the user.

Advanced cryogenics for cutting tools. Final report  

SciTech Connect

The purpose of the investigation was to determine if cryogenic treatment improved the life and cost effectiveness of perishable cutting tools over other treatments or coatings. Test results showed that in five of seven of the perishable cutting tools tested there was no improvement in tool life. The other two tools showed a small gain in tool life, but not as much as when switching manufacturers of the cutting tool. The following conclusions were drawn from this study: (1) titanium nitride coatings are more effective than cryogenic treatment in increasing the life of perishable cutting tools made from all cutting tool materials, (2) cryogenic treatment may increase tool life if the cutting tool is improperly heat treated during its origination, and (3) cryogenic treatment was only effective on those tools made from less sophisticated high speed tool steels. As a part of a recent detailed investigation, four cutting tool manufacturers and two cutting tool laboratories were queried and none could supply any data to substantiate cryogenic treatment of perishable cutting tools.

Efficient discrete-time simulations of continuous-time quantum query algorithms  

E-Print Network (OSTI)

The continuous-time query model is a variant of the discrete query model in which queries can be interleaved with known operations (called "driving operations") continuously in time. Interesting algorithms have been discovered in this model, such as an algorithm for evaluating nand trees more efficiently than any classical algorithm. Subsequent work has shown that there also exists an efficient algorithm for nand trees in the discrete query model; however, there is no efficient conversion known for continuous-time query algorithms for arbitrary problems. We show that any quantum algorithm in the continuous-time query model whose total query time is T can be simulated by a quantum algorithm in the discrete query model that makes O[T log(T) / log(log(T))] queries. This is the first upper bound that is independent of the driving operations (i.e., it holds even if the norm of the driving Hamiltonian is very large). A corollary is that any lower bound of T queries for a problem in the discrete-time query model immediately carries over to a lower bound of \\Omega[T log(log(T))/log (T)] in the continuous-time query model.

An Overview of the Lawrence Berkeley Laboratory Extended Entity-Relationship Database Tools  

E-Print Network (OSTI)

In this overview we briefly describe a collection of tools developed at Lawrence Berkeley Laboratory (LBL) for aiding users in specifying database structures and in querying databases using object-oriented concepts on top of commercial relational database management systems. These tools are based on an Extended Entity-Relationship (EER) model and allow users to deal with concise EER structures and queries rather than relational database definitions and queries which are usually large, hard to maintain, and involve terms that obscure the semantics of the application. Using the LBL/EER database tools users are insulated from the underlying database management system, and thus can avoid learning database management specific concepts and query languages. 1 Introduction Database applications involve large amounts of data that must be maintained and made available to users for analysis and manipulation. Database management systems (DBMSs) provide the capabilities required for stor...

FastQuery: A Parallel Indexing System for Scientific Data  

SciTech Connect

Modern scientific datasets present numerous data management and analysis challenges. State-of-the- art index and query technologies such as FastBit can significantly improve accesses to these datasets by augmenting the user data with indexes and other secondary information. However, a challenge is that the indexes assume the relational data model but the scientific data generally follows the array data model. To match the two data models, we design a generic mapping mechanism and implement an efficient input and output interface for reading and writing the data and their corresponding indexes. To take advantage of the emerging many-core architectures, we also develop a parallel strategy for indexing using threading technology. This approach complements our on-going MPI-based parallelization efforts. We demonstrate the flexibility of our software by applying it to two of the most commonly used scientific data formats, HDF5 and NetCDF. We present two case studies using data from a particle accelerator model and a global climate model. We also conducted a detailed performance study using these scientific datasets. The results show that FastQuery speeds up the query time by a factor of 2.5x to 50x, and it reduces the indexing time by a factor of 16 on 24 cores.

Efficient query recommendations in the long tail via center-piece subgraphs  

E-Print Network (OSTI)

We present a recommendation method based on the wellknown concept of center-piece subgraph, that allows for the time/space efficient generation of suggestions also for rare, i.e., long-tail queries. Our method is scalable with respect to both the size of datasets from which the model is computed and the heavy workloads that current web search engines have to deal with. Basically, we relate terms contained into queries with highly correlated queries in a query-flow graph. This enables a novel recommendation generation method able to produce recommendations for approximately 99 % of the workload of a real-world search engine. The method is based on a graph having term nodes, query nodes, and two kinds of connections: term-query and query-query. The first connects a term to the queries in which it is contained, the second connects two query nodes if the likelihood that a user submits the second query after having issued the first one is sufficiently high. On such large graph we need to compute the center-piece subgraph induced by terms contained into queries. In order to reduce the cost of the above computation, we introduce a novel and efficient method based on an inverted index representation of the model. We experiment our solution on two real-world query logs and we show that its effectiveness is comparable (and in some case better) than state-of-the-art methods for head-queries. More importantly, the quality of the recommendations generated remains very high also for long-tail queries, where other methods fail even to produce any suggestion. Finally, we extensively investigate scalability and efficiency issues and we show the viability of our method in real world search engines. 1.

QCS : a system for querying, clustering, and summarizing documents.  

Science Conference Proceedings (OSTI)

Information retrieval systems consist of many complicated components. Research and development of such systems is often hampered by the difficulty in evaluating how each particular component would behave across multiple systems. We present a novel hybrid information retrieval system--the Query, Cluster, Summarize (QCS) system--which is portable, modular, and permits experimentation with different instantiations of each of the constituent text analysis components. Most importantly, the combination of the three types of components in the QCS design improves retrievals by providing users more focused information organized by topic. We demonstrate the improved performance by a series of experiments using standard test sets from the Document Understanding Conferences (DUC) along with the best known automatic metric for summarization system evaluation, ROUGE. Although the DUC data and evaluations were originally designed to test multidocument summarization, we developed a framework to extend it to the task of evaluation for each of the three components: query, clustering, and summarization. Under this framework, we then demonstrate that the QCS system (end-to-end) achieves performance as good as or better than the best summarization engines. Given a query, QCS retrieves relevant documents, separates the retrieved documents into topic clusters, and creates a single summary for each cluster. In the current implementation, Latent Semantic Indexing is used for retrieval, generalized spherical k-means is used for the document clustering, and a method coupling sentence ''trimming'', and a hidden Markov model, followed by a pivoted QR decomposition, is used to create a single extract summary for each cluster. The user interface is designed to provide access to detailed information in a compact and useful format. Our system demonstrates the feasibility of assembling an effective IR system from existing software libraries, the usefulness of the modularity of the design, and the value of this particular combination of modules.

Large-Scale Continuous Subgraph Queries on Streams  

SciTech Connect

Graph pattern matching involves finding exact or approximate matches for a query subgraph in a larger graph. It has been studied extensively and has strong applications in domains such as computer vision, computational biology, social networks, security and finance. The problem of exact graph pattern matching is often described in terms of subgraph isomorphism which is NP-complete. The exponential growth in streaming data from online social networks, news and video streams and the continual need for situational awareness motivates a solution for finding patterns in streaming updates. This is also the prime driver for the real-time analytics market. Development of incremental algorithms for graph pattern matching on streaming inputs to a continually evolving graph is a nascent area of research. Some of the challenges associated with this problem are the same as found in continuous query (CQ) evaluation on streaming databases. This paper reviews some of the representative work from the exhaustively researched field of CQ systems and identifies important semantics, constraints and architectural features that are also appropriate for HPC systems performing real-time graph analytics. For each of these features we present a brief discussion of the challenge encountered in the database realm, the approach to the solution and state their relevance in a high-performance, streaming graph processing framework.

Towards Optimal Multi-Dimensional Query Processing with BitmapIndices  

Science Conference Proceedings (OSTI)

Bitmap indices have been widely used in scientific applications and commercial systems for processing complex, multi-dimensional queries where traditional tree-based indices would not work efficiently. This paper studies strategies for minimizing the access costs for processing multi-dimensional queries using bitmap indices with binning. Innovative features of our algorithm include (a) optimally placing the bin boundaries and (b) dynamically reordering the evaluation of the query terms. In addition, we derive several analytical results concerning optimal bin allocation for a probabilistic query model. Our experimental evaluation with real life data shows an average I/O cost improvement of at least a factor of 10 for multi-dimensional queries on datasets from two different applications. Our experiments also indicate that the speedup increases with the number of query dimensions.

Simulation tools  

E-Print Network (OSTI)

In the last two decades, simulation tools made a significant contribution to the great progress in development of power electronics. Time to market was shortened and development costs were reduced drastically. Falling costs, as well as improved speed and precision, opened new fields of application. Today, continuous and switched circuits can be mixed. A comfortable number of powerful simulation tools is available. The users have to choose the best suitable for their application. Here a simple rule applies: The best available simulation tool is the tool the user is already used to (provided, it can solve the task). Abilities, speed, user friendliness and other features are continuously being improved—even though they are already powerful and comfortable. This paper aims at giving the reader an insight into the simulation of power electronics. Starting with a short description of the fundamentals of a simulation tool as well as properties of tools, several tools are presented. Starting with simplified models ...

Minimizing I/O Costs of Multi-Dimensional Queries with BitmapIndices  

Science Conference Proceedings (OSTI)

Bitmap indices have been widely used in scientific applications and commercial systems for processing complex,multi-dimensional queries where traditional tree-based indices would not work efficiently. A common approach for reducing the size of a bitmap index for high cardinality attributes is to group ranges of values of an attribute into bins and then build a bitmap for each bin rather than a bitmap for each value of the attribute. Binning reduces storage costs,however, results of queries based on bins often require additional filtering for discarding it false positives, i.e., records in the result that do not satisfy the query constraints. This additional filtering,also known as ''candidate checking,'' requires access to the base data on disk and involves significant I/O costs. This paper studies strategies for minimizing the I/O costs for ''candidate checking'' for multi-dimensional queries. This is done by determining the number of bins allocated for each dimension and then placing bin boundaries in optimal locations. Our algorithms use knowledge of data distribution and query workload. We derive several analytical results concerning optimal bin allocation for a probabilistic query model. Our experimental evaluation with real life data shows an average I/O cost improvement of at least a factor of 10 for multi-dimensional queries on datasets from two different applications. Our experiments also indicate that the speedup increases with the number of query dimensions.

Group-based Query Learning for rapid diagnosis in time-critical situations  

E-Print Network (OSTI)

In query learning, the goal is to identify an unknown object while minimizing the number of "yes or no" questions (queries) posed about that object. We consider three extensions of this fundamental problem that are motivated by practical considerations in real-world, time-critical identification tasks such as emergency response. First, we consider the problem where the objects are partitioned into groups, and the goal is to identify only the group to which the object belongs. Second, we address the situation where the queries are partitioned into groups, and an algorithm may suggest a group of queries to a human user, who then selects the actual query. Third, we consider the problem of query learning in the presence of persistent query noise, and relate it to group identification. To address these problems we show that a standard algorithm for query learning, known as the splitting algorithm or generalized binary search, may be viewed as a generalization of Shannon-Fano coding. We then extend this result to t...

An interoperable, data-structure-neutral component for mesh query and manipulation.  

Science Conference Proceedings (OSTI)

Much of the effort required to create a new simulation code goes into developing infrastructure for mesh data manipulation, adaptive refinement, design optimization, and so forth. This infrastructure is an obvious target for code reuse, except that implementations of these functionalities are typically tied to specific data structures. In this article, we describe a software component---an abstract data model and programming interface---designed to provide low-level mesh query and manipulation support for meshing and solution algorithms. The component's data model provides a data abstraction, completely hiding all details of how mesh data is stored, while its interface defines how applications can interact with that data. Because the component has been carefully designed to be general purpose and efficient, it provides a practical platform for implementing high-level mesh operations independently of the underlying mesh data structures. After describing the data model and interface, we provide several usage examples, each of which has been used successfully with multiple implementations of the interface functionality. The overhead due to accessing mesh data through the interface rather than directly accessing the underlying mesh data is shown to be acceptably small.

Query and Visualization of extremely large network datasets over the web using Quadtree based KML Regional Network Links  

SciTech Connect

Geographic data sets are often very large in size. Interactive visualization of such data at all scales is not easy because of the limited resolution of the monitors and inability of visualization applications to handle the volume of data. This is especially true for large vector datasets. The end user s experience is frequently unsatisfactory when exploring such data over the web using a naive application. Network bandwidth is another contributing factor to the low performance. In this paper, a Quadtree based technique to visualize extremely large spatial network datasets over the web is described. It involves using custom developed algorithms leveraging a PostGIS database as the data source and Google Earth as the visualization client. This methodology supports both point and range queries along with non-spatial queries. This methodology is demonstrated using a network dataset consisting of several million links. The methodology is based on using some of the powerful features of KML (Keyhole Markup Language). Keyhole Markup Language (KML) is an Open Geospatial Consortium (OGC) standard for displaying geospatial data on Earth browsers. One of the features of KML is the notion of Network Links. Using network links, a wide range of geospatial data sources such as geodatabases, static files and geospatial data services can be simultaneously accessed and visualized seamlessly. Using the network links combined with Level of Detail principle, view based rendering and intelligent server and client-side caching, scalability in visualizing extremely large spatial datasets can be achieved.

Evaluation of physical characteristics and phenomena, sensitivity and interaction effects, performance criteria and output requirements for a station keeping subsystem engineering evaluation tool (SKEET)  

DOE Green Energy (OSTI)

The fundamental purpose for SKEET is to provide a means of simulating and evaluating OTEC platform SKSS performance. This evaluation capability may be employed in the process of a design review, comparison of alternative concepts, operational planning, establishing risk and reliability criteria and a host of other applications. However, the central requirement is that SKEET have the capability to predict the excursions on motions of the platform and loads on the SKSS as a result of environmental effects under a range of operational conditions. The principal elements which should be represented by the SKEET model include: environment (wind, current, waves); vessel/CWP configuration; mooring system (including anchor/soil and electrical riser cable interactions); and dynamic positioning system effects. Findings are summarized of the following two tasks that have been undertaken to formulate a definition of the requirements of SKEET: Task III - identify and classify the physical characteristics and phenomena and evaluate interaction effects; and Task IV - establish mooring performance criteria. The objective of Task III was to define the range of physical parameters that must be incorporated into SKEET and to make an assessment of the most appropriate manner in which to incorporate each of those parameters. The objective of Task IV was to define the required outputs from SKEET. (WHK)

Query estimation and order-optimized iteration in very large federations  

SciTech Connect

Objectivity federated databases may contain many terabytes of data and span thousands of files. In such an environment, it is often easy for a user to pose a query that may return an iterator over millions of objects, requiring opening thousands of databases. This presentation describes several technologies developed for such settings: (1) a query estimator, which tells the user how many objects satisfy the query, and how many databases will be touched, prior to opening all of those files; (2) an order-optimized iterator, which behaves like an ordinary iterator except that elements are returned in an order optimized for efficient access, presorted by the database (and container) in which they reside; (3) a parallel implementation of the order-optimized iterator, allowing any number of processes in a parallel or distributed system to iterate over disjoint subcollections of terms satisfying the query, partitioned by the database or container in which the items reside. These technologies have been developed for scientific experiments that will require handling thousands of terabytes of data annually, but they are intended to be applicable in other massive data settings as well. In such environments, significant amounts of data will reside on tertiary storage, accessible via Objectivity`s recently-announced HPSS (High Performance Storage System) interface. When deployed in large-scale physics settings later in 1998, the query estimator will further inform the user of the number of tape mounts required to satisfy the query, and provide rough time estimates for data delivery. The order-optimized iterator will be connected to a cache manager that will prefetch from tape to disk the files needed by the query (known from the query estimation step), and will decide which items to deliver to the user next according to the order in which data become available in the disk cache.

Execution) is a tracing system developed by Larus and Ball which is incorporated as part of the Gnu C compiler [3]. Its goal is to generate very small traces which can be saved and then reused for multiple simulation runs. The modified compiler actually produces two executable programs. The first is the modified application. In addition to normal compilation, the compiler uses the notion of abstract execution to insert tracing code in the application code. Abstract execution is based upon control-flow tracing to reduce the amount of trace code necessary. The resulting trace produced by the modified application is only a tiny part of the full trace. This allows traces representing long execution runs to be saved on disk. The compiler also produces an application specific trace regeneration program. The regeneration program is a post-processing tool which accepts the compacted trace and outputs the full execution trace. The tracing overhead, including the cost of saving the compacted tra...

Adaptive time-to-live strategies for query result caching in web search engines  

E-Print Network (OSTI)

Abstract. An important research problem that has recently started to receive attention is the freshness issue in search engine result caches. In the current techniques in literature, the cached search result pages are associated with a fixed time-to-live (TTL) value in order to bound the staleness of search results presented to the users, potentially as part of a more complex cache refresh or invalidation mechanism. In this paper, we propose techniques where the TTL values are set in an adaptive manner, on a per-query basis. Our results show that the proposed techniques reduce the fraction of stale results served by the cache and also decrease the fraction of redundant query evaluations on the search engine backend compared to a strategy using a fixed TTL value for all queries.

A Framework for Moving Sensor Data Query and Retrieval of Dynamic Atmospheric Events  

E-Print Network (OSTI)

Abstract. One challenge in Earth science research is the accurate and efficient ad-hoc query and retrieval of Earth science satellite sensor data based on user-defined criteria to study and analyze atmospheric events such as tropical cyclones. The problem can be formulated as a spatiotemporal join query to identify the spatio-temporal location where moving sensor objects and dynamic atmospheric event objects intersect, either precisely or within a user-defined proximity. In this paper, we describe an efficient query and retrieval framework to handle the problem of identifying the spatio-temporal intersecting positions for satellite sensor data retrieval. We demonstrate the effectiveness of our proposed framework using sensor measurements from QuikSCAT (wind field measurement) and TRMM (precipitation vertical profile measurements) satellites, and the trajectories of the tropical cyclones occurring in the North Atlantic Ocean in 2009. Key words: data retrieval, satellite data, atmospheric events, spatiotemporal

Science Conference Proceedings (OSTI)

The visualization and analysis of AMR-based simulations is integral to the process of obtaining new insight in scientific research. We present a new method for performing query-driven visualization and analysis on AMR data, with specific emphasis on time-varying AMR data. Our work introduces a new method that directly addresses the dynamic spatial and temporal properties of AMR grids which challenge many existing visualization techniques. Further, we present the first implementation of query-driven visualization on the GPU that uses a GPU-based indexing structure to both answer queries and efficiently utilize GPU memory. We apply our method to two different science domains to demonstrate its broad applicability.

Bridging the Virtual Observatory and the GRID with the query element  

E-Print Network (OSTI)

The current generation of Grid infrastructures designed for production activity is strongly computing oriented and tuned on the needs of applications that requires intensive computations. Problems arise when trying to use such Grids to satisfy the sharing of data-oriented and service-oriented resources as happens in the IVOA community. We have designed, developed and implemented a Grid query element to access data source from an existing production Grid environment. We also enhanced the Grid middleware model (collective resources and sites) to manage Data Sources extending the Grid semantic. The query element and the modified grid Information System are able to connect the Grid environment to Virtual Observatory resources. A specialized query element is designed to work as Virtual Observatory resource in the Grid so than an Astronomer can access Virtual Observatory data using the IVOA standards.

An Algorithmic Argument for Nonadaptive Query Complexity Lower Bounds on Advised Quantum Computation  

E-Print Network (OSTI)

This paper employs a powerful argument, called an algorithmic argument, to prove lower bounds of the quantum query complexity of a multiple-block ordered search problem in which, given a block number i, we are to find a location of a target keyword in an ordered list of the i-th block. Apart from much studied polynomial and adversary methods for quantum query complexity lower bounds, our argument shows that the multiple-block ordered search needs a large number of nonadaptive oracle queries on a black-box model of quantum computation that is also supplemented with advice. Our argument is also applied to the notions of computational complexity theory: quantum truth-table reducibility and quantum truth-table autoreducibility.

More than a decade ago, word processing software revolutionized the way documents were prepared, and productivity was increased. But the editing and formatting capabilities of most word processors did very little to prevent errors in spelling, typing, grammar, diction, style, or organization from slipping through to the final documents. In the past few years, the number of software tools that aid the author has increased substantially. They now vary in scope from simple spelling checkers to sophisticated diction analyzers and idea processors. Moreover, writing-aid-software described in this report is now available for many types of computing systems, including personal computers, scientific workstations, and mainframes. The various pieces of software can be used in interactive or non-interactive (batch) modes.

Rule-based query answering method for a knowledge base of economic crimes  

E-Print Network (OSTI)

We present a description of the PhD thesis which aims to propose a rule-based query answering method for relational data. In this approach we use an additional knowledge which is represented as a set of rules and describes the source data at concept (ontological) level. Queries are posed in the terms of abstract level. We present two methods. The first one uses hybrid reasoning and the second one exploits only forward chaining. These two methods are demonstrated by the prototypical implementation of the system coupled with the Jess engine. Tests are performed on the knowledge base of the selected economic crimes: fraudulent disbursement and money laundering.

Midcontinent Interactive Digital Carbon Atlas and Relational Database (MIDCARB)  

Science Conference Proceedings (OSTI)

This annual report describes progress of the project entitled ''Midcontinent Interactive Digital Carbon Atlas and Relational Database (MIDCARB)''. This project, funded by the Department of Energy, is a cooperative project that assembles a consortium of five states (Indiana, Illinois, Kansas, Kentucky and Ohio) to construct an online distributed Relational Database Management System (RDBMS) and Geographic Information System (GIS) covering aspects of carbon dioxide geologic sequestration (http://www.midcarb.org). The system links the five states in the consortium into a coordinated regional database system consisting of datasets useful to industry, regulators and the public. The project is working to provide advanced distributed computing solutions to link database servers across the five states into a single system where data is maintained at the local level but is accessed through a single Web portal and can be queried, assembled, analyzed and displayed. Each individual state has strengths in data gathering, data manipulation and data display, including GIS mapping, custom application development, web development, and database design. Sharing of expertise provides the critical mass of technical expertise to improve CO{sub 2} databases and data access in all states. This project improves the flow of data across servers in the five states and increases the amount and quality of available digital data. The MIDCARB project is developing improved online tools to provide real-time display and analyze CO{sub 2} sequestration data. The system links together data from sources, sinks and transportation within a spatial database that can be queried online. Visualization of high quality and current data can assist decision makers by providing access to common sets of high quality data in a consistent manner.

Ficsr: Feedback-based InConSistency Resolution and query processing on misaligned data sources  

E-Print Network (OSTI)

A critical reality in data integration is that knowledge from different sources may often be conflicting with each other. Conflict resolution can be costly and, if done without proper context, can be ineffective. In this paper, we propose a novel query-driven and feedback-based approach (FICSR 1) to conflict resolution when integrating data sources. In particular, instead of relying on traditional model based definition of consistency, we introduce a ranked interpretation. This not only enables FICSR to deal with the complexity of the conflict resolution process, but also helps achieve a more direct match between the users ’ (subjective) interpretation of the data and the system’s (objective) treatment of the available alternatives. Consequently, the ranked interpretation leads to new opportunities for bi-directional (data informs ? ? user) feedback cycle for conflict resolution: given a query, (a) a preliminary ranking of candidate results on data can inform the user regarding constraints critical to the query, while (b) user feedback regarding the ranks can be exploited to inform the system about user’s relevant domain knowledge. To enable this feedback process, we develop data structures and algorithms for efficient off-line conflict/agreement analysis of the integrated data as well as for on-line query processing, candidate result enumeration, and validity analysis. The results are brought together and evaluated in the FICSR system.

Non-Uniform Data Complexity of Query Answering in Description Logics  

E-Print Network (OSTI)

In ontology-based data access (OBDA), ontologies are used as an interface for querying instance data. Since in typical applications the size of the data is much larger than the size of the ontology and query, data complexity is the most important complexity measure. In this paper, we propose a new method for investigating data complexity in OBDA: instead of classifying whole logics according to their complexity, we aim at classifying each individual ontology within a given master language. Our results include a P/coNP-dichotomy theorem for ontologies of depth one in the description logic ALCFI, the equivalence of a P/coNP-dichotomy theorem for ALC/ALCI-ontologies of unrestricted depth to the famous dichotomy conjecture for CSPs by Feder and Vardi, and a non-P/coNP-dichotomy theorem for ALCF-ontologies.

Comprehensive Metadata Query Interface for Heterogeneous Data Archives Based on Open Source PostgreSQL ORDBMS  

E-Print Network (OSTI)

We use PostgreSQL DBMS for storing XML metadata, described by the IVOA Characterisation Data Model. Initial XML type support in the PostgreSQL has recently been implemented. We make heavy use of this feature in order to provide comprehensive search over Characterisation metadata tree. We built a prototype of the Characterisation metadata query service, implementing two access methods: (1) HTTP-GET/POST based interface implements almost direct translation of the query parameter name into XPath of the data model element in the XML serialisation; (2) Web-Service based interface to receive XQuery which is also directly translated into XPath. This service will be used in the ASPID-SR archive, containing science-ready data obtained with the Russian 6-m telescope.

An Information-Theoretic Privacy Criterion for Query Forgery in Information Retrieval  

E-Print Network (OSTI)

In previous work, we presented a novel information-theoretic privacy criterion for query forgery in the domain of information retrieval. Our criterion measured privacy risk as a divergence between the user's and the population's query distribution, and contemplated the entropy of the user's distribution as a particular case. In this work, we make a twofold contribution. First, we thoroughly interpret and justify the privacy metric proposed in our previous work, elaborating on the intimate connection between the celebrated method of entropy maximization and the use of entropies and divergences as measures of privacy. Secondly, we attempt to bridge the gap between the privacy and the information-theoretic communities by substantially adapting some technicalities of our original work to reach a wider audience, not intimately familiar with information theory and the method of types.

DUK - A Fast and Efficient Kmer Based Sequence Matching Tool  

SciTech Connect

A new tool, DUK, is developed to perform matching task. Matching is to find whether a query sequence partially or totally matches given reference sequences or not. Matching is similar to alignment. Indeed many traditional analysis tasks like contaminant removal use alignment tools. But for matching, there is no need to know which bases of a query sequence matches which position of a reference sequence, it only need know whether there exists a match or not. This subtle difference can make matching task much faster than alignment. DUK is accurate, versatile, fast, and has efficient memory usage. It uses Kmer hashing method to index reference sequences and Poisson model to calculate p-value. DUK is carefully implemented in C++ in object oriented design. The resulted classes can also be used to develop other tools quickly. DUK have been widely used in JGI for a wide range of applications such as contaminant removal, organelle genome separation, and assembly refinement. Many real applications and simulated dataset demonstrate its power.

Bin-Hash Indexing: A Parallel Method for Fast Query Processing  

SciTech Connect

This paper presents a new parallel indexing data structure for answering queries. The index, called Bin-Hash, offers extremely high levels of concurrency, and is therefore well-suited for the emerging commodity of parallel processors, such as multi-cores, cell processors, and general purpose graphics processing units (GPU). The Bin-Hash approach first bins the base data, and then partitions and separately stores the values in each bin as a perfect spatial hash table. To answer a query, we first determine whether or not a record satisfies the query conditions based on the bin boundaries. For the bins with records that can not be resolved, we examine the spatial hash tables. The procedures for examining the bin numbers and the spatial hash tables offer the maximum possible level of concurrency; all records are able to be evaluated by our procedure independently in parallel. Additionally, our Bin-Hash procedures access much smaller amounts of data than similar parallel methods, such as the projection index. This smaller data footprint is critical for certain parallel processors, like GPUs, where memory resources are limited. To demonstrate the effectiveness of Bin-Hash, we implement it on a GPU using the data-parallel programming language CUDA. The concurrency offered by the Bin-Hash index allows us to fully utilize the GPU's massive parallelism in our work; over 12,000 records can be simultaneously evaluated at any one time. We show that our new query processing method is an order of magnitude faster than current state-of-the-art CPU-based indexing technologies. Additionally, we compare our performance to existing GPU-based projection index strategies.

A METHOD FOR ESTIMATING GAS PRESSURE IN 3013 CONTAINERS USING AN ISP DATABASE QUERY  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy's Integrated Surveillance Program (ISP) is responsible for the storage and surveillance of plutonium-bearing material. During storage, plutonium-bearing material has the potential to generate hydrogen gas from the radiolysis of adsorbed water. The generation of hydrogen gas is a safety concern, especially when a container is breached within a glove box during destructive evaluation. To address this issue, the DOE established a standard (DOE, 2004) that sets the criteria for the stabilization and packaging of material for up to 50 years. The DOE has now packaged most of its excess plutonium for long-term storage in compliance with this standard. As part of this process, it is desirable to know within reasonable certainty the total maximum pressure of hydrogen and other gases within the 3013 container if safety issues and compliance with the DOE standards are to be attained. The principal goal of this investigation is to document the method and query used to estimate total (i.e. hydrogen and other gases) gas pressure within a 3013 container based on the material properties and estimated moisture content contained in the ISP database. Initial attempts to estimate hydrogen gas pressure in 3013 containers was based on G-values (hydrogen gas generation per energy input) derived from small scale samples. These maximum G-values were used to calculate worst case pressures based on container material weight, assay, wattage, moisture content, container age, and container volume. This paper documents a revised hydrogen pressure calculation that incorporates new surveillance results and includes a component for gases other than hydrogen. The calculation is produced by executing a query of the ISP database. An example of manual mathematical computations from the pressure equation is compared and evaluated with results from the query. Based on the destructive evaluation of 17 containers, the estimated mean absolute pressure was significantly higher (P.10) between the mean pressures from DR and the calculation. The mean predicted absolute pressure was consistently higher than GEST by an average difference of 57 kPa (8 psi). The mean difference between the estimated pressure and digital radiography was 11 kPa (2 psi). Based on the initial results of destructive evaluation, the pressure query was found to provide a reasonably conservative estimate of the total pressure in 3013 containers whose material contained minimal moisture content.

A METHOD FOR ESTIMATING GAS PRESSURE IN 3013 CONTAINERS USING AN ISP DATABASE QUERY  

DOE Green Energy (OSTI)

The U.S. Department of Energy's Integrated Surveillance Program (ISP) is responsible for the storage and surveillance of plutonium-bearing material. During storage, plutonium-bearing material has the potential to generate hydrogen gas from the radiolysis of adsorbed water. The generation of hydrogen gas is a safety concern, especially when a container is breached within a glove box during destructive evaluation. To address this issue, the DOE established a standard (DOE, 2004) that sets the criteria for the stabilization and packaging of material for up to 50 years. The DOE has now packaged most of its excess plutonium for long-term storage in compliance with this standard. As part of this process, it is desirable to know within reasonable certainty the total maximum pressure of hydrogen and other gases within the 3013 container if safety issues and compliance with the DOE standards are to be attained. The principal goal of this investigation is to document the method and query used to estimate total (i.e. hydrogen and other gases) gas pressure within a 3013 container based on the material properties and estimated moisture content contained in the ISP database. Initial attempts to estimate hydrogen gas pressure in 3013 containers was based on G-values (hydrogen gas generation per energy input) derived from small scale samples. These maximum G-values were used to calculate worst case pressures based on container material weight, assay, wattage, moisture content, container age, and container volume. This paper documents a revised hydrogen pressure calculation that incorporates new surveillance results and includes a component for gases other than hydrogen. The calculation is produced by executing a query of the ISP database. An example of manual mathematical computations from the pressure equation is compared and evaluated with results from the query. Based on the destructive evaluation of 17 containers, the estimated mean absolute pressure was significantly higher (P<.01) than the mean GEST pressure. There was no significant difference (P>.10) between the mean pressures from DR and the calculation. The mean predicted absolute pressure was consistently higher than GEST by an average difference of 57 kPa (8 psi). The mean difference between the estimated pressure and digital radiography was 11 kPa (2 psi). Based on the initial results of destructive evaluation, the pressure query was found to provide a reasonably conservative estimate of the total pressure in 3013 containers whose material contained minimal moisture content.

Solving Similarity Joins and Range Queries in Metric Spaces with the List of Twin Clusters  

E-Print Network (OSTI)

The metric space model abstracts many proximity or similarity problems, where the most frequently considered primitives are range and k-nearest neighbor search, leaving out the similarity join, an extremely important primitive. In fact, despite the great attention that this primitive has received in traditional and even multidimensional databases, little has been done for general metric databases. We solve two variants of the similarity join problem: (1) range joins: Given two sets of objects and a distance threshold r, find all the object pairs (one from each set) at distance at most r; and (2) k-closest pair joins: Find the k closest object pairs (one from each set). For this sake, we devise a new metric index, coined List of Twin Clusters (LTC), which indexes both sets jointly, instead of the natural approach of indexing one or both sets independently. Finally, we show how to use the LTC in order to solve classical range queries. Our results show significant speedups over the basic quadratic-time naive alternative for both join variants, and that the LTC is competitive with the original list of clusters when solving range queries. Furthermore, we show that our technique has a great potential for improvements.

Raising the IQ in full-text searching via intelligent querying  

SciTech Connect

Current Information Retrieval (IR) technologies allow for efficient access to relevant information, provided that user selected query terms coincide with the specific linguistical choices made by the authors whose works constitute the text-base. Therefore, the challenge is to enhance the limited searching capability of state-of-the-practice IR. This can be done either with augmented clients that overcome current server searching deficiencies, or with added capabilities that can augment searching algorithms on the servers. The technology being investigated is that of deductive databases, with a set of new techniques called cooperative answering. This technology utilizes semantic networks to allow for navigation between possible query search term alternatives. The augmented search terms are passed to an IR engine and the results can be compared. The project utilizes the OSTI Environment, Safety and Health Thesaurus to populate the domain specific semantic network and the text base of ES&H related documents from the Facility Profile Information Management System as the domain specific search space.

Overcoming Scalability Challenges for Tool Daemon Launching  

SciTech Connect

Many tools that target parallel and distributed environments must co-locate a set of daemons with the distributed processes of the target application. However, efficient and portable deployment of these daemons on large scale systems is an unsolved problem. We overcome this gap with LaunchMON, a scalable, robust, portable, secure, and general purpose infrastructure for launching tool daemons. Its API allows tool builders to identify all processes of a target job, launch daemons on the relevant nodes and control daemon interaction. Our results show that Launch-MON scales to very large daemon counts and substantially enhances performance over existing ad hoc mechanisms.

Tool setting device  

DOE Patents (OSTI)

The present invention relates to a tool setting device for use with numerically controlled machine tools, such as lathes and milling machines. A reference position of the machine tool relative to the workpiece along both the X and Y axes is utilized by the control circuit for driving the tool through its program. This reference position is determined for both axes by displacing a single linear variable displacement transducer (LVDT) with the machine tool through a T-shaped pivotal bar. The use of the T-shaped bar allows the cutting tool to be moved sequentially in the X or Y direction for indicating the actual position of the machine tool relative to the predetermined desired position in the numerical control circuit by using a single LVDT.

Data Parallel Bin-Based Indexing for Answering Queries on Multi-Core Architectures  

SciTech Connect

The multi-core trend in CPUs and general purpose graphics processing units (GPUs) offers new opportunities for the database community. The increase of cores at exponential rates is likely to affect virtually every server and client in the coming decade, and presents database management systems with a huge, compelling disruption that will radically change how processing is done. This paper presents a new parallel indexing data structure for answering queries that takes full advantage of the increasing thread-level parallelism emerging in multi-core architectures. In our approach, our Data Parallel Bin-based Index Strategy (DP-BIS) first bins the base data, and then partitions and stores the values in each bin as a separate, bin-based data cluster. In answering a query, the procedures for examining the bin numbers and the bin-based data clusters offer the maximum possible level of concurrency; each record is evaluated by a single thread and all threads are processed simultaneously in parallel. We implement and demonstrate the effectiveness of DP-BIS on two multi-core architectures: a multi-core CPU and a GPU. The concurrency afforded by DP-BIS allows us to fully utilize the thread-level parallelism provided by each architecture--for example, our GPU-based DP-BIS implementation simultaneously evaluates over 12,000 records with an equivalent number of concurrently executing threads. In comparing DP-BIS's performance across these architectures, we show that the GPU-based DP-BIS implementation requires significantly less computation time to answer a query than the CPU-based implementation. We also demonstrate in our analysis that DP-BIS provides better overall performance than the commonly utilized CPU and GPU-based projection index. Finally, due to data encoding, we show that DP-BIS accesses significantly smaller amounts of data than index strategies that operate solely on a column's base data; this smaller data footprint is critical for parallel processors that possess limited memory resources (e.g., GPUs).

Web queries with style: Rendering xcerpt programs with css-ng  

E-Print Network (OSTI)

Abstract. Styling and formatting of XML documents for various target media is often specified with the Cascading Style Sheet (CSS) language. An appealing feature of CSS is that it specifies formatting instructions using rather simple guarded rules. A limitation of CSS is that it focuses on static formatting rules. As a consequence scripting languages such as ECMA Script are used in practice for dynamic adaptation of formatting. CSS NG is a novel extension of CSS 3, the newest version of CSS, introducing just a few rules for a dynamic rendering and for markup visualization. This limited extension of CSS 3 turns out to make possible a rather advanced visualization of programs. This article (1) introduces into the extensions of CSS NG with respect to CSS 3, (2) describes a proof-of-concept prototype implementation of CSS NG, and (3) demonstrates CSS NG on Xcerpt query programs. 1

Value-of-Information based Middleware for Autonomic Querying of Distributed Sensor Databases  

SciTech Connect

With particular focus on distributed situational awareness in defense and security applications, we propose a value-of-information based middleware framework as a paradigm shift from crawl-index based centralized search. The proposed approach seeks to improve efficiency in search and retrieval by transforming sensors into programmable information points and enabling ubiquitous data and software flows through the infrastructure of the distributed network. We explain the different components of such a middleware framework to organize, tag and notify emerging spatial, temporal and causal patterns from the sensor measurements. We conclude the paper with a brief discussion on the top-down programming model that can realize the framework as a reconfigurable sensor query system.

MIDCONTINENT INTERACTIVE DIGITAL CARBON ATLAS AND RELATIONAL DATABASE (MIDCARB)  

Science Conference Proceedings (OSTI)

This annual report describes progress in the second year of the three-year project entitled ''Midcontinent Interactive Digital Carbon Atlas and Relational Database (MIDCARB)''. This project, funded by the Department of Energy, is a cooperative project that assembles a consortium of five states (Indiana, Illinois, Kansas, Kentucky and Ohio) to construct an online distributed Relational Database Management System (RDBMS) and Geographic Information System (GIS) covering aspects of carbon dioxide geologic sequestration (http://www.midcarb.org). The system links the five states in the consortium into a coordinated regional database system consisting of datasets useful to industry, regulators and the public. The project is providing advanced distributed computing solutions to link database servers across the five states into a single system where data is maintained at the local level but is accessed through a single Web portal and can be queried, assembled, analyzed and displayed. Each individual state has strengths in data gathering, data manipulation and data display, including GIS mapping, custom application development, web development, and database design. Sharing of expertise provides the critical mass of technical expertise to improve CO{sub 2} databases and data access in all states. This project improves the flow of data across servers in the five states and increases the amount and quality of available digital data. Data is being assembled to analyze CO{sub 2} sequestration potential from a single object (e.g., power plant or well) to a region and across geographic boundaries. The MIDCARB system is robust and capable of being updated from multiple sources on a daily basis. The MIDCARB project has developed improved online tools to provide real-time display and analysis of CO{sub 2} sequestration data. The MIDCARB project is a functional template for distributed data systems to address CO{sub 2} sequestration and other natural resource issues that cross the boundaries between institutions and geographic areas. The system links together data from sources, sinks and transportation within a spatial database that can be queried online. Visualization of high quality and current data can assist decision makers by providing access to common sets of high quality data in a consistent manner.

NetCDF (designed by Unidata) is relatively compact, is appendable, is capable of storing descriptive "meta-data" along with measurement data, and is platform-independent. However, the organization of data within netCDF files tends to follow conventions reflecting either the source or the end use of the data. Consequently, tools developed for use with netCDF files following one convention may not be optimal for use with those following another convention. For example, tools designed for examination of geographically-gridded data may not be well-suited for analysis of time-series data such as that generated by ARM. In addition, some of the

OOTW Force Design Tools  

Science Conference Proceedings (OSTI)

This report documents refined requirements for tools to aid the process of force design in Operations Other Than War (OOTWs). It recommends actions for the creation of one tool and work on other tools relating to mission planning. It also identifies the governmental agencies and commands with interests in each tool, from whom should come the user advisory groups overseeing the respective tool development activities. The understanding of OOTWs and their analytical support requirements has matured to the point where action can be taken in three areas: force design, collaborative analysis, and impact analysis. While the nature of the action and the length of time before complete results can be expected depends on the area, in each case the action should begin immediately. Force design for OOTWs is not a technically difficult process. Like force design for combat operations, it is a process of matching the capabilities of forces against the specified and implied tasks of the operation, considering the constraints of logistics, transport and force availabilities. However, there is a critical difference that restricts the usefulness of combat force design tools for OOTWs: the combat tools are built to infer non-combat capability requirements from combat capability requirements and cannot reverse the direction of the inference, as is required for OOTWs. Recently, OOTWs have played a larger role in force assessment, system effectiveness and tradeoff analysis, and concept and doctrine development and analysis. In the first Quadrennial Defense Review (QDR), each of the Services created its own OOTW force design tool. Unfortunately, the tools address different parts of the problem and do not coordinate the use of competing capabilities. These tools satisfied the immediate requirements of the QDR, but do not provide a long-term cost-effective solution.

Graphitic packing removal tool  

DOE Patents (OSTI)

Graphitic packing removal tools are described for removal of the seal rings in one piece from valves and pumps. The packing removal tool has a cylindrical base ring the same size as the packing ring with a surface finish, perforations, knurling or threads for adhesion to the seal ring. Elongated leg shanks are mounted axially along the circumferential center. A slit or slits permit insertion around shafts. A removal tool follower stabilizes the upper portion of the legs to allow a spanner wrench to be used for insertion and removal.

Python Tools Python Tools Python Tools Description and Overview Python is an interpreted, general-purpose high-level programming language. Various of versions of Python are installed on most of the NERSC systems, usually accompanied with computational tool such as numpy and scipy. Using Python on NERSC Systems To use the python installed as module on NERSC systems, you need do module load python To run a python script on the Hopper and Edison compute nodes, you must set an environment variable: setenv CRAY_ROOTFS DSL which is set automatically when the python module is loaded. To execute a script on the Hopper or Edison compute nodes dedicated to your job, you need to use aprun: aprun -n 1 python ./hello_world.py or, if the script is executable and contains '#!/usr/bin/env python' as the
