This book presents a detailed look at high-lift aerodynamics, which deals with the aerodynamic behavior of lift augmentation means from various approaches. After an introductory chapter, the book discusses the physical limits of lift generation, giving the lift generation potential. It then explains what is needed for an aircraft to fly safely by analyzing the high-lift-related requirements for certifying an aircraft. Aircraft needs are also analyzed to improve performance during takeoff, approach, and landing. The book discusses in detail the applied means to increase the lift coefficient by either passive and active high-lift systems. It includes slotless and slotted high-lift flaps, active and passive vortex generating devices, boundary and circulation control, and powered lift.

The distributed energy resource (DER) refers to the small-scale energy generation and storage units, as well as flexible loads. Microgrids are distribution systems with a group of interconnected loads and DERs within clearly defined electrical boundaries that act as a single controllable entity with respect to the main grid. A microgrid can connect and disconnect from the main grid to enable it to operate in both grid-connected and islanded modes. This book focuses on three research problems of the DERs in the microgrid: planning, operation, and control. The planning aims to determine the optimal size and site as well as investment plan of the DER units in the microgrid over a long-time horizon, e.g., 5 years to 20 years; The operation of the microgrid focuses on the operational dispatch horizon over a short-term time interval, e.g., from 5 minutes to a few hours or one day. The objective is to dispatch the DERs for optimal energy management and bus voltage regulation; The control of the microgrid is concerned on the real-time timescale, i.e., milliseconds to seconds, and the objective is to maintain the voltages and frequency within desired operational ranges, achieve power sharing and balancing among DERs and loads.

There is huge potential for smaller wind turbines to provide clean energy around the world. Small wind turbines come in a variety of designs, and have similarities in principles and technology to small hydrokinetic turbines (SHKTs). SHKTs, in turn, can play an important role in hydropower. Small wind and hydrokinetic systems can even work together, for example, to power farms, communities, campuses, rural as well as remote rural areas, and island regions. This concise book, written by experts in the field, provides an in-depth overview of small turbines for wind and hydropower. Chapters cover resource assessment for wind and water, turbine technology, design of vertical and horizontal axis turbines, blade element analysis, vibration-based energy harvesting, very low head turbines, diffuser augmented wind turbines, and numerous case studies.

Direct Current (DC) transmission and distribution technologies have evolved in recent years. They offer superior efficiency, current carrying capacity, and response times as compared to conventional AC systems. Further, substantial advantages are their natural interface with many types of renewable energy resources, such as photovoltaic systems and battery energy storage systems at relatively high voltage, and compliance with consumer electronics at lower voltages, say, within a household environment. One of the core building blocks of DC-based technologies, especially at medium voltage levels, is power electronic systems technology. This cannot be emphasized enough as these units process, convert, and regulate all DC power and provide intelligence and sensing as electric power grids evolve.

How can cognition, a concept traditionally associated with the human brain, be applied to satellite systems? For the first time, cognitive system meanings and models are applied to the uncertain environmental processes of satellite systems. The authors of this book go beyond defining 'cognitive satellite systems' to design a cognitive satellite communication system architecture with satellite-to-ground coordination, which has uses in emergency response spacecraft and prediction technology. This book puts forward the concept of “cognitive satellite”, based on cognitive sciences such as cognitive radio and cognitive radar, and forms intelligent payloads with flexible reconstruction of functional components and various modern signal processing technologies. Cognitive satellite is a spatial information system capable of autonomously processing complex dynamic information in space. Traditional satellites include hardware resources and software resources. Hardware resources include vehicles, spacecraft, and ground stations. Software resources include spectrum and information resources. Cognitive satellites are a further upgrade of satellites in the traditional sense.
