  6. Interpretation of HRTEM images by image simulation: An introduction to theory and practice

    SciTech Connect (OSTI)

    O`Keefe, M.A.

    1994-08-01

    This tutorial describes the use of image simulation as an aid to interpretation of high-resolution transmission electron microscope images. Topics include some image processing as well as image simulation. Image processing is the manipulation of experimental images in order to extract some desired information. Image simulation is the generation of a computed or simulated image from a model structure. It requires a detailed knowledge of the process of image formation in the high-resolution transmission electron microscope. This tutorial concentrates on image simulation, with examples of image processing appearing only as required as illustrations. Because this is an introduction, the theory of image simulation is described, but not explored in depth. The practice of image simulation is covered in sufficient detail to enable the student to understand the functions of the various steps in the computations, and the parameters necessary for their evaluation.

  1. Images of energy: Policy perspectives on the introduction of hydroelectricity in Italy, 1882-1914

    SciTech Connect (OSTI)

    Laszlo, A.R.

    1992-01-01

    This study considers the link between energy technologies and cultural attitudes. Contemporary energy policy makers lack the conceptual tools with which to evaluate culturally appropriate energy choices. A way to regain a contextual capability is needed; that is, the capacity to recognize and avert situations where technological advance is insufficiently harmonized with its embedding environment. This study explores how both policy makers and the general public form their [open quotes]images of energy.[close quotes] It does so in three parts, beginning with an examination of the concepts of [open quotes]technology,[close quotes] [open quotes]culture[close quotes] and [open quotes]cognitive map,[close quotes] and an explanation of their interrelationship. The second part presents two historical case-studies of the introduction of hydroelectricity in Italy from 1882-1914. It considers how a relatively unknown technology made its way into urban and rural life, who its primary surveyors were, and how it shaped and was shaped by the cognitive maps of those into whose lives it marched. The final part extends the investigation to contemporary socio-cultural dynamics. Through concepts derived from General System Theory, the process of technological integration is interpreted in light of events that shape the world today. The design of a model to be used by energy makers and educators alike in conceiving culturally attuned energy alternatives is proposed. Such a model would describe energy-related cognitive maps and could serve as the basis for informed decision-making on energy choice at all levels of society. The study concludes with suggestions for a research agenda to further explore individual and collective energy-related cognitive maps.

  7. Introduction of heat map to fidelity assessment of compressed CT images

    2011-08-15

    Purpose: This study aimed to introduce heat map, a graphical data presentation method widely used in gene expression experiments, to the presentation and interpretation of image fidelity assessment data of compressed computed tomography (CT) images. Methods: The authors used actual assessment data that consisted of five radiologists' responses to 720 computed tomography images compressed using both Joint Photographic Experts Group 2000 (JPEG2000) 2D and JPEG2000 3D compressions. They additionally created data of two artificial radiologists, which were generated by partly modifying the data from two human radiologists. Results: For each compression, the entire data set, including the variations among radiologists and among images, could be compacted into a small color-coded grid matrix of the heat map. A difference heat map depicted the advantage of 3D compression over 2D compression. Dendrograms showing hierarchical agglomerative clustering results were added to the heat maps to illustrate the similarities in the data patterns among radiologists and among images. The dendrograms were used to identify two artificial radiologists as outliers, whose data were created by partly modifying the responses of two human radiologists. Conclusions: The heat map can illustrate a quick visual extract of the overall data as well as the entirety of large complex data in a compact space while visualizing the variations among observers and among images. The heat map with the dendrograms can be used to identify outliers or to classify observers and images based on the degree of similarity in the response patterns.

    1 A Synergetic Study of Solar Fluxes and Aerosol Properties Under Clear-Sky Conditions A. Trishchenko and Z. Li Canada Center for Remote Sensing Ottawa, Ontario, Canada Introduction Several recent studies indicate that our ability to model the transfer of solar flux in the clear atmosphere is still fraught with significant uncertainties (Arking 1996; Charlock and Alberta 1996; Kato et al. 1997; Li et al. 1997; Halthore et. al 1997). The treatment of aerosol is often considered as a more likely

    Shortwave Cloud Radiative Forcing: Magnitude, Biases, and Uncertainties A. P. Trishchenko and Z. Li Canada Centre for Remote Sensing Ottawa, Ontario, Canada Introduction Cloud radiative forcing (CRF) has been employed widely in studying the effects of cloud on the earth's radiation budget. By its definition, CRF denotes the influence of cloud only on radiative fluxes. However, in practice, observational determination of CRF is fraught with uncertainties due to variations in many factors other

    ARM-UAV: The Next Phase J. Vitko, Jr. and T. P. Tooman Sandia National Laboratories Livermore, California R. G. Ellingson University of Maryland College Park, Maryland Introduction The Atmospheric Radiation Measurement-Unmanned Aerospace Vehicle (ARM-UAV) Program was initiated in 1993 to develop a capability to provide radiation and cloud measurements at the top of the troposphere, thereby capping the top of the grid cell above ARM sites. To date, ARM-UAV has developed the necessary payloads and

    7 Relative Humidity Variations in the Tropical Western Pacific and Relations with Deep Convective Clouds J. Wang and J. A. Curry Program in Atmospheric and Oceanic Sciences University of Colorado Boulder, Colorado Introduction Most general circulation models (GCMs) agree that water vapor feedback due to warming caused by increasing greenhouse gases is positive (Cess et al. 1990). However, Lindzen (1990) argued that GCMs might overestimate the water vapor feedback because increased convection in
