W artykule przedstawiono aktywne metody balansowania ogniw, spośród których wybrano metodę zastosowaną w systemie nadzorującym i zarządzającym baterią ogniw (BMS). Potrzeba opracowania systemu ...nadzorującego i zarządzającego baterią wynika z zastosowania ogniw nowej generacji, litowych, bardzo wrażliwych na przeładowanie. Umożliwia on zabezpieczenie baterii ogniw zarówno przed skutkami nierównomiernego doładowywania, jak również przed przeładowaniem. W artykule wyjaśniono cel balansowania, opisano metodę bateria do ogniwa zastosowaną w systemie BMS aktualnie wdrażanym w ciągniku podwieszanym PCA-1 oraz przedstawiono nowe rozwiązanie systemu BMS.
This comprehensive book gives an overview of how cognitive systems and artificial intelligence (AI) can be used in electronic warfare (EW). Readers will learn how EW systems respond more quickly and ...effectively to battlefield conditions where sophisticated radars and spectrum congestion put a high priority on EW systems that can characterize and classify novel waveforms, discern intent, and devise and test countermeasures. Specific techniques are covered for optimizing a cognitive EW system as well as evaluating its ability to learn new information in real time.The book presents AI for electronic support (ES), including characterization, classification, patterns of life, and intent recognition. Optimization techniques, including temporal tradeoffs and distributed optimization challenges are also discussed. The issues concerning real-time in-mission machine learning and suggests some approaches to address this important challenge are presented and described. The book covers electronic battle management, data management, and knowledge sharing. Evaluation approaches, including how to show that a machine learning system can learn how to handle novel environments, are also discussed. Written by experts with first-hand experience in AI-based EW, this is the first book on in-mission real-time learning and optimization.
From materials to applications, this ready reference covers the entire value chain from fundamentals via processing right up to devices, presenting different approaches to large-area electronics, ...thus enabling readers to compare materials, properties and performance. Divided into two parts, the first focuses on the materials used for the electronic functionality, covering organic and inorganic semiconductors, including vacuum and solution-processed metal-oxide semiconductors, nanomembranes and nanocrystals, as well as conductors and insulators. The second part reviews the devices and applications of large-area electronics, including flexible and ultra-high-resolution displays, light-emitting transistors, organic and inorganic photovoltaics, large-area imagers and sensors, non-volatile memories and radio-frequency identification tags.
