A texture description is useful in many applications including similarity based image search and browsing. We present here three texture descriptors that are being considered for the final committee draft of the ISO/MPEG-7 standard. A comprehensive overview of the syntax and semantics of these texture descriptors is provided. The Homogeneous Texture Descriptor (HTD) and the Edge Histogram Descriptor (EHD) are useful in similarity search. The HTD characterizes homogeneous texture regions and is also useful in texture classification and recognition. The EHD is applicable when the underlying texture is not homogeneous and can also be used in sketch based retrieval. In addition, a compact descriptor that facilitates browsing applications is also defined. These descriptors are selected after a highly competitive test and evaluation phase within the MPEG group and we briefly summarize the evaluation criteria, the datasets used and the experimental results.

Defense systems are complex and expensive and decision makers acquiring these systems aspire better value for money. As part of a procurement decision, test and evaluation (T&E) is conducted to assess if the system is meeting desired requirements. This chapter reviews the concepts in T&E for weapon systems in the navy and presents the process for its implementation. The authors point out the role of modeling and simulation and how to use them to support T&E. The review reveals that developmental and operational T&E can examine weapon systems requirements before their deployment, T&E process can effectively be implemented in six steps, and mission/capacity requirements must be decomposed into predefined evaluation criteria.

Abstract Background The purpose of this work was to design, validate and implement a media-fill test combined with fluorescein (MFT-F) for the specific qualification and training of radiopharmacy operators, in accordance with United States Pharmacopeia General Chapter 797 and European Good Manufacturing Practices. MFT-F was embedded in the quality management system of our radiopharmacy unit. Its validation involved fluorescein concentration choice, media growth promotion test and evaluation protocol controls (with or without intentional aseptic mistakes). Each operator was evaluated following a three-part evaluation form. Evaluation criteria related to garbing and hygiene, fluorescent contamination and bacteriological contamination (pre- and post-evaluation environment controls and MFT-F samples). Combined MFT-F allowed the assessment of aseptic compounding skills and non-contamination of the working area through a single evaluation. It was also designed to fit the constraints of radiopharmacy common practice related to radiation protection equipment and to the small volumes handled. Results A 0.01% fluorescein concentration was chosen to prepare MFT-F. Addition of fluorescein in the culture medium did not jeopardize its growth properties according to growth promotion test. Eleven operators were evaluated and carried out 3 MFT-F over 3 successive days. Pre- and post-evaluation bacteriological controls of every session showed no CFU of microbiological contaminant above 5. All operators validated the garbing and hygiene evaluation, with an average score of 92.7%. All operators validated the fluorescent contamination evaluation, with an average score of 29.4 out of 30. None of the MFT-F samples showed any visible bacterial growth after incubation. Conclusions Combined MFT-F, as a part of a comprehensive sterile compounding training program, appeared as a convenient and promising tool to increase both the sterile compounding safety and awareness of radioactive contamination in radiopharmacy.

Crash Tests

During the past decade, reducing the severity of side-impact collisions has been an emerging area of research by a variety of organizations and research communities. The motor vehicle manufacturing and regulatory communities in the United States, Europe, and many other countries have developed dynamic side-impact test and evaluation criteria to reduce the severity of vehicle-to-vehicle side-impact collisions. Similarly, the international research community has developed test procedures for performing impacts into poles, one of the most severe types of side-impact collisions. Preliminary side-impact test and evaluation procedures have been conducted for roadside safety hardware, like guardrails, guardrail terminals, luminaire supports, utility poles, and signs. Recommendations for performing roadside hardware side-impact crash tests are summarized; the results of several side-impact roadside hardware crash tests are described; the proposed test and evaluation procedures are compared with other major side-impact test and evaluation procedures; and areas requiring further research are discussed.

Testing And Evaluation

Historically, research and development efforts, and testing and evaluation (T&E), activities, were separate and distinct from each other. At that time, the goals of T&E were predominantly two: 1. To determine whether or not the system met requirements 2. To determine whether or not the system “worked”? Testing focused on factors that influence task performance. Evaluation criteria were often specified in general design guidelines and specifications, or in system requirements documents. And, the majority of T&E efforts were expended in conjunction with military systems. Today, development, testing, and evaluation are routinely performed as part of the concurrent engineering process. Research, if conducted at all, is likely to be focused on situation-specific issues. The previously stated T&E goals are still valid, but T&E practitioners may also be expected to provide design recommendations. Testing of task performance is still a high priority, but testing may also be performed to assess usability, workload, situation awareness, safety, and acceptance by operational and maintenance personnel. The beginning of a new millennium is an appropriate time to examine this redefined problem space. The presentations by our four panelists will illuminate some of these changes and describe how we may react to them.

Kognitive Funktionen

Zusammenfassung. Theoretischer Hintergrund: Kognitive Funktionseinschränkungen sind zentrales Merkmal schizophrener Erkrankungen und werden entsprechend im Behandlungskonzept berücksichtigt. Kognitive Remediationsprogramme gelten als wirksam, Effektstärken als moderat. Trainingsvarianten werden zur Effektoptimierung erprobt. Fragestellung: Ist gezieltes Funktionstraining in neuroplastizitäts-orientiertem Lernkontext effektiver als breitgefächertes Behandlungsprogramm und werden Effekte durch das Erkrankungsstadium moduliert? Methode: Bei 59 chronisch und 31 ersthospitalisierten schizophren Erkrankten wurden kognitive Defizite über Testleistungen der MATRICS Consensus Cognitive Test Battery gegenüber 25 gesunder Kontrollpersonen erfasst. Testleistungen vor, nach 4-wöchiger Interventionsphase mit zwei spezifischen Trainings oder Standardbehandlung und 3-monatiger Katamnese prüften den Einfluss von Interventionstypus und Erkrankungsstadium auf Leistungsverbesserung. Ergebnisse: Sowohl chronische wie erstmals behandelte Patienten aller Behandlungsgruppen verbesserten sich signifikant über die Messzeitpunkte, obwohl Defizite relativ zu Kontrollen fortbestanden. Schlussfolgerungen: Spezifisches Training verbessert kognitive Funktionen nicht über Zeit/Remissionseffekte hinaus.
