Softcover/Taschenbuch. Condición: Neu. Industrial firefighting is performed in complex and high-risk environments where effective performance depends not only on physical fitness and technical skills but also on cognitive capabilities. This book examines the role of cognitive factors in the operational performance of industrial firefighters using an integrated DEMATEL-ANP-SEM approach. The study was conducted among 141 industrial firefighters in the Mahshahr Petrochemical Special Economic Zone, Iran. DEMATEL and ANP were used to identify causal relationships and prioritize cognitive performance-shaping factors, while Structural Equation Modeling was applied to validate their relationships with operational performance. Situation awareness, risk perception, and attention were identified as the three highest-priority factors. All three showed significant positive associations with operational performance, with standardized coefficients of ?=0.46, ?=0.38, and ?=0.31, respectively. The findings highlight the importance of cognitive capabilities in firefighter performance assessment, competency evaluation, and training. Sprache: Englisch Gewicht in Gramm: 96.…

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Ultra-wideband (UWB) is a promising technology for high speed short distance communication, as well as low data-rate low power communication for object localization and sensor networks. The most important characteristic of UWB is the operation in power-limited regime while achieving high channel capacity. The main challenge lies in designing transceivers for wideband signals.Distributed integrated circuits provide intrinsic wideband characteristics, which makes them potential candidate for use in UWB transceivers. Recent advances in high-speed IC design with continuous scaling of minimum feature sizes of silicon technologies have renewed the interest in distributed circuits using on-chip transmission lines. Silicon-Based RF Front-Ends for UWB Radios comprehensively studies silicon-based distributed architectures in wideband circuits.The book begins with an introduction of several transceiver architectures for UWB. The discussion then focuses on RF front-end of the UWB radio. First, the design and analysis of a performance-optimized CMOS distributed LNA is presented. This is followed by design of novel distributed RF front-ends for UWB IF-receivers (UWB-DRF). The book continues with the introduction of a novel distributed direct conversion RF front-end (DDC-RF). The DDC-RF power and area-efficiently combines the wideband distributed approach with IQ requirement of a direct conversion receiver. Furthermore, deploying merged LNA/mixer enables low-power design, while achieving superior linearity over the conventional distributed amplifiers. The baseband output signals are zero/ low-IF, hence the output transmission lines in conventional distributed circuits are omitted, resulting in less area of the DDC-RF. To increase data rate and to achieve immunity to multi-path fading, UWB systems employs multi-antenna configuration at receiver/transmitter. Innovative wideband variable delay and gain stages are then introduced to receive and transmit in desired direction. Finally, experimental results of the fabricated prototypes are presented.Silicon-Based RF Front-Ends for UWB Radios will be of interest to RF circuit designers and students.…

Gebundene Ausgabe. Condición: Neu. One of the leading causes of automobile accidents is the slow reaction of the driver while responding to a hazardous situation. State-of-the-art wireless electronics can automate several driving functions, leading to significant reduction in human error and improvement in vehicle safety. With continuous transistor scaling, silicon fabrication technology now has the potential to substantially reduce the cost of automotive radar sensors. This book bridges an existing gap between information available on dependable system/architecture design and circuit design. It provides the background of the field and detailed description of recent research and development of silicon-based radar sensors. System-level requirements and circuit topologies for radar transceivers are described in detail. Holistic approaches towards designing radar sensors are validated with several examples of highly-integrated radar ICs in silicon technologies. Circuit techniques to design millimeter-wave circuits in silicon technologies are discussed in depth. Sprache: Englisch Gewicht in Gramm: 284.…

Softcover/Taschenbuch. Condición: Neu. La lucha contra incendios industriales se lleva a cabo en entornos complejos y de alto riesgo, en los que un desempe?o eficaz depende no solo de la forma f?sica y las habilidades t?cnicas, sino tambi?n de las capacidades cognitivas. Este libro analiza el papel de los factores cognitivos en el desempe?o operativo de los bomberos industriales mediante un enfoque integrado que combina los modelos DEMATEL, ANP y SEM. El estudio se llev? a cabo entre 141 bomberos industriales de la Zona Econ?mica Especial Petroqu?mica de Mahshahr, en Ir?n. Se utilizaron los modelos DEMATEL y ANP para identificar relaciones causales y priorizar los factores cognitivos que influyen en el rendimiento, mientras que se aplic? el modelo de ecuaciones estructurales para validar sus relaciones con el rendimiento operativo. La conciencia situacional, la percepci?n del riesgo y la atenci?n se identificaron como los tres factores de mayor prioridad. Los tres mostraron asociaciones positivas significativas con el rendimiento operativo, con coeficientes estandarizados de ? = 0,46, ? = 0,38 y ? = 0,31, respectivamente. Los resultados ponen de relieve la importancia de las capacidades cognitivas en la evaluaci?n del rendimiento, la evaluaci?n de competencias y la formaci?n de los bomberos.
