COMMON AIRBORNE INSTRUMENTATION SYSTEM; A FRESH LOOK

Grace, Thomas 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The US Government originally funded the development of the Common Airborne Instrumentation System (CAIS) to address industry-wide compatibility, maintenance, and commonality issues. Although initially targeted for US Department of Defense (DoD) programs, CAIS is also being used throughout the world in many commercial applications. This paper provides a fresh look at the evolution of the CAIS concept starting with some historical background of the CAIS Program, an overview of the CAIS System Architecture and recent trends in the use of “Commercial Off The Shelf (COTS)” products and technology.

"Avaliação objetiva da isquemia de membros superiores: uso do dinamômetro isocinético" / Objective evaluation of upper limbs ischemia: use of isokinetic dynamometer

Nakano, Livio 13 September 2005 (has links)
O objetivo deste trabalho é apresentar o teste de esforço com o dinamômetro isocinético na avaliação objetiva da isquemia funcional da doença arterial oclusiva de membros superiores (DAOMS). Reuniu-se 23 pacientes com DAOMS unilateral, no grupo 1. Sete pacientes, sem DAOMS foram selecionados como o grupo controle (grupo 2). Os membros testados sem DAOMS do grupo 1 e do grupo 2 não apresentaram diferença estatística. A comparação de cada membro dos pacientes do grupo 1, com e sem DAOMS mostrou que os membros com DAOMS apresentaram desempenho significativamente menor que os membros sem lesão. Este teste permite a avaliação objetiva da limitação causada pela DAOMS de forma segura e objetiva / The objective of this work is to present the results of a stress test using an isokinetic dynamometer in patients with occlusive arterial disease in upper limbs (OADUL). Group 1 has 23 patients with unilateral subclavian occlusive disease. Seven patients, without OADUL, were included in a control group (group 2). No statistically difference was found in all parameters studied between limbs without OADUL in groups 1 and 2. So, each arm in group 1 (with and without OADUL) were tested. For all these parameters, the SOD limbs presented significantly lower values than the control limbs. This test gives an objective grade of limitation of the muscle function in patients with OADUL

Testovací metody pro hodnocení radiačních efektů v přesných analogových a signálově smíšených obvodech pro aplikace v kosmické elektronice / Test Methods for Evaluation of Radiation Effects in High Precision Analog and Mixed-Signal Devices for Space Applications

Hofman, Jiří January 2019 (has links)
The traditional radiation testing of space electronics has been used for more than fifty years to support the radiation hardness assurance. Its typical goal is to ensure reliable operation of the spacecraft in the harsh environment of space. This PhD research looks into the radiation testing from a different perspective; the goal is to develop radiation testing methods that are focused not only on the reliability of the components but also on a continuous radiation-induced degradation of their performance. Such data are crucial for the understanding of the impact of radiation on the measurement uncertainty of data acquisition systems onboard research space missions.
