Initial Experiences with Retrieving Similar Objects in Simulation Data

Description: Comparing the output of a physics simulation with an experiment, referred to as 'code validation,' is often done by visually comparing the two outputs. In order to determine which simulation is a closer match to the experiment, more quantitative measures are needed. In this paper, we describe our early experiences with this problem by considering the slightly simpler problem of finding objects in a image that are similar to a given query object. Focusing on a dataset from a fluid mixing problem, we report on our experiments with different features that are used to represent the objects of interest in the data. These early results indicate that the features must be chosen carefully to correctly represent the query object and the goal of the similarity search.

ALEGRA-HEDP validation strategy.

Description: This report presents a initial validation strategy for specific SNL pulsed power program applications of the ALEGRA-HEDP radiation-magnetohydrodynamics computer code. The strategy is written to be (1) broadened and deepened with future evolution of particular specifications given in this version; (2) broadly applicable to computational capabilities other than ALEGRA-HEDP directed at the same pulsed power applications. The content and applicability of the document are highly constrained by the R&D thrust of the SNL pulsed power program. This means that the strategy has significant gaps, indicative of the flexibility required to respond to an ongoing experimental program that is heavily engaged in phenomena discovery.

Software Verification and Validation Plan Activities, 2011, Project Number: N6423, SAPHIRE Version 8

Description: The SV&V Plan experienced changes over the past year to bring it into the operational software life cycle of SAPHIRE 8 and to maintain its sections on design features. Peer review of the SVVP with the former IV&V members identified the need for the operational use of metrics as a tool for quality maintenance and improvement. New tests were added to the SVVP to verify the operation of the new design features incorporated into SAPHIRE 8. Other additions to the SVVP were the addition of software metrics and the PDR and CDR processes. Audit support was provided for the NRC Technical Manager and Project Manager for the NRC OIG Audit performed throughout 2011. The SVVP is considered to be an up to date reference and useful roadmap of verification and validation activities going forward.

SAPHIRE 8 Software Independent Verification and Validation Plan

Description: SAPHIRE 8 is being developed with a phased or cyclic iterative rapid application development methodology. Due to this approach, a similar approach is being taken for the IV&V activities on each vital software object. The IV&V plan is structured around NUREG/BR-0167, “Software Quality Assurance Program and Guidelines,” February 1993. The Nuclear Regulatory Research Office Instruction No.: PRM-12, “Software Quality Assurance for RES Sponsored Codes,” March 26, 2007 specifies that RES-sponsored software is to be evaluated against NUREG/BR-0167. Per the guidance in NUREG/BR-0167, SAPHIRE is classified as “Level 1.” Level 1 software corresponds to technical application software used in a safety decision.

Assessing middle school students` understanding of science relationships and processes: Year 2 - instrument validation. Final report

Description: Our overall purpose for this multi-year project was to develop an alternative assessment format measuring rural middle school students understanding of science concepts and processes and the interrelationships among them. This kind of understanding is called structural knowledge. We had 3 major interrelated goals: (1) Synthesize the existing literature and critically evaluate the actual and potential use of measures of structural knowledge in science education. (2) Develop a structural knowledge alternative assessment format. (3) Examine the validity of our structural knowledge format. We accomplished the first two goals during year 1. The structural knowledge assessment we identified and developed further was a select-and-fill-in concept map format. The goal for our year 2 work was to begin to validate this assessment approach. This final report summarizes our year 2 work.

Value of Laboratory Experiments for Code Validations

Description: Numerical codes have become indispensable for designing underground structures and interpretating the behavior of geologic systems. Because of the complexities of geologic systems, however, code calculations often are associated with large quantitative uncertainties. This papers presents three examples to demonstrate the value of laboratory(or bench scale) experiments to evaluate the predictive capabilities of such codes with five major conclusions: Laboratory or bench-scale experiments are a very cost-effective, controlled means of evaluating and validating numerical codes, not instead of but before or at least concurrent with the implementation of in situ studies. The design of good laboratory validation tests must identifj what aspects of a code are to be scrutinized in order to optimize the size, geometry, boundary conditions, and duration of the experiments. The design of good and sometimes difficult numerical analyses and sensitivity studies. Laboratory validation tests must involve: Good validation experiments will generate independent data sets to identify the combined effect of constitutive models, model generalizations, material parameters, and numerical algorithms. Successfid validations of numerical codes mandate a close collaboration between experimentalists and analysts drawing from the full gamut of observations, measurements, and mathematical results.

Validation Of The Facet Satisfaction Scale (Fss): An Evaluative Approach To Assessing Facet Job Satisfaction

Description: Job satisfaction has, and continues to be an important construct of interest to researchers and practitioners alike. However, conflicting operational definitions and inconsistent measurement systems have reduced the efficacy of the construct in predicting important job-related outcomes for organizations and their employees. The Facet Satisfaction Scale (FSS) was designed to overcome these deficiencies by creating a facet-based measure that assesses job satisfaction in accordance with recent definitions of the construct. Reliability and validity analyses were conducted on both the complete and shortened version of the scale. The FSS exhibited evidence of reliability (ranging from .52 to .93 for the shortened FSS, and .53 to .96 for the complete FSS). Evidence of scale validity was also obtained through the use of construct, content, and criterion-related validity measures. Implications of the study on future research on job satisfaction are discussed.

The Validation of a Short-cycle Formative Assessment Observation Protocol for Science and Mathematics Instruction

Description: Over the years, teachers, administrators, and policy makers have been concerned with optimizing learning for all students. The No Child Left Behind Act put an emphasis on summative assessments, which measure what students have learned. In contrast, formative assessment has been shown in many studies to improve student achievement and motivation because it is applied while students are learning. The purpose of this study was to investigate, for middle and high school mathematics and science instruction, the validity and reliability of a newly developed observation instrument called AssessToday, which is used in a single class period to assess a teacher’s use of short-cycle formative assessment. The content validity of the instrument was supported through an extensive literature review, feedback from experts in the field of formative assessment, and an examination of 98 classroom observations. For assessing reliability of the instrument, inter-rater reliability coefficients were calculated using data collected by trained observers who independently rated teachers during the same class period using three measures: percentage of agreement between raters, Cohen’s kappa, and Fleiss kappa. Cohen’s kappa (N = 36 pairs) ranged from .62 to 1.00 for all observer pairs with an average kappa of .75 for mathematics (n = 16 pairs) and .76 for science (n = 20 pairs). The recommended threshold for kappa is k = .70. An exploratory factor analysis was conducted on the observation data and the determined factors related to the theoretical framework established in the literature. The results affirmed that the instrument is a tool to be utilized in short-cycle formative assessment with middle and high school science and mathematics teachers.

Bigfoot Field Manual, Version 2.1

Description: The BigFoot Project is funded by the Earth Science Enterprise to collect and organize data to be used in the National Aeronautics and Space Administration's Earth Observing System (EOS) Validation Program. The data collected by the BigFoot Project are unique in being ground-based observations coincident with satellite overpasses. In addition to collecting data, the BigFoot project will develop and test new algorithms for scaling point measurements to the same spatial scales as the EOS satellite products. This BigFoot Field Manual will be used to achieve completeness and consistency of data collected at four initial BigFoot sites and at future sites that may collect similar validation data. Therefore, validation datasets submitted to the Oak Ridge National Laboratory Distributed Active Archive Center that have been compiled in a manner consistent with the field manual will be especially valuable in the validation program.

Iterative build OMIT maps: Map improvement by iterative model-building and refinement without model bias

Description: A procedure for carrying out iterative model-building, density modification and refinement is presented in which the density in an OMIT region is essentially unbiased by an atomic model. Density from a set of overlapping OMIT regions can be combined to create a composite 'Iterative-Build' OMIT map that is everywhere unbiased by an atomic model but also everywhere benefiting from the model-based information present elsewhere in the unit cell. The procedure may have applications in the validation of specific features in atomic models as well as in overall model validation. The procedure is demonstrated with a molecular replacement structure and with an experimentally-phased structure, and a variation on the method is demonstrated by removing model bias from a structure from the Protein Data Bank.

ILC Vertex Tracker R&D

Description: This document summarizes past achievements, current activities and future goals of the R&D program aimed at the design, prototyping and characterization of a full detector module, equipped with monolithic pixel sensors, matching the requirements for the Vertex Tracker at the ILC. We provide a plan of activities to obtain a demonstrator multi-layered vertex tracker equipped with sensors matching the ILC requirements and realistic lightweight ladders in FY11, under the assumption that ILC detector proto-collaborations will be choosing technologies and designs for the Vertex Tracker by that time. The R&D program discussed here started at LBNL in 2004, supported by a Laboratory Directed R&D (LDRD) grant and by funding allocated from the core budget of the LBNL Physics Division and from the Department of Physics at UC Berkeley. Subsequently additional funding has been awarded under the NSF-DOE LCRD program and also personnel have become available through collaborative research with other groups. The aim of the R&D program carried out by our collaboration is to provide a well-integrated, inclusive research effort starting from physics requirements for the ILC Vertex Tracker and addressing Si sensor design and characterization, engineered ladder design, module system issues, tracking and vertex performances and beam test validation. The broad scope of this program is made possible by important synergies with existing know-how and concurrent programs both at LBNL and at the other collaborating institutions. In particular, significant overlaps with LHC detector design, SLHC R&D as well as prototyping for the STAR upgrade have been exploited to optimize the cost per deliverable of our program. This activity is carried out as a collaborative effort together with Accelerator and Fusion Research, the Engineering and the Nuclear Science Divisions at LBNL, INFN and the Department of Physics in Padova, Italy, INFN and the Department of Physics in Torino, Italy and the ...
