This paper reviews state-of-the-art progress with respect to MW wind generator-converter configurations, wind farm configurations and grid code compliance methods. Four categories of generator-converter configurations have been identified and analyzed based on component count, modularity, reliability, converter/control complexity, device voltage stress, operation voltage, and achievable power levels.

The theory of electromagnetic leaky waves can explain a variety of electromagnetic phenomena and scenarios, from microwave to visible frequencies. In the field of wave physics, the damping of harmonic oscillations in time and/or space is associated with losses in a dissipative system. Moreover, in open systems, oscillation energy gradually gets lost in the form of radiation toward the remote boundaries of an open region, reducing the amplitude of oscillations, even in a nondissipative system. This effect occurs with radioactive states in quantum mechanics, with damped resonances in open acoustic or electromagnetic cavities, and with leaky-waves in open waveguiding structures. The theory of electromagnetic leaky waves can explain a variety of electromagnetic phenomena and scenarios, from microwave to visible frequencies.

Due to its scalability and on-demand resource flexibility, cloud computing has emerged as an economical means for pay-as-you-go computing. Infrastructure-as-a-Service (IaaS) cloud platforms host large and successful company services; however, virtual machine (VM) performance is unpredictable, which can noticeably impact a tenant's service-level agreement. Resource contention between VMs is the main culprit; it leads to degradation and variation, also known as “performance overhead.” Overhead can be so severe that it will hinder users from moving critical business services into the cloud. Overhead manifests alternately as increased execution time, decreased network throughput, and uneven application performance over a period of time. Performance overhead has been studied under three scenarios: the single-server virtualization, the single large datacenter, and multiple geodistributed datacenters.

Despite the fact that wide bandgap (WBG) semiconductor materials - in particular, silicon carbide (SiC) and gallium nitride (GaN)-have superior electrical and thermal characteristics when compared to silicon, making them promising candidates for use in compact high-power converters, the commercialization of SiC and GaN has been quite slow in arriving.

When Irish mathematician William Hamilton first described the number system called quaternions in 1843, it was applied to the field of mechanics only. The quaternion, the quotient of two directed lines or vectors in 3-D space, was for Hamilton a fundamental structural component of the universe. Hamilton inspired Maxwell to write his famous electromagnetic equations in terms of quaternions; however, they proved to be unwieldy and ineffective for that purpose. This prompted others (namely, Heaviside, Gibbs, and Helmholtz) to develop a simpler system for vector analysis that would be more readily adopted by physicists and engineers.

In the last decade, progress has been made in the construction of simple neuromorphic cognitive systems. These types of circuits are described in the paper, and they are compared to existing solutions. The limitations of such circuits are described, as well as design techniques for constructing larger brain-like systems. The technological building blocks are based on dynamic synapse circuits, hardware models of spiking neurons, and spike-based plasticity circuits, which are integrated into multichip spiking recurrent and winner-take-all neural networks, which can serve as models for pattern recognition, working memory, decision making, and state-dependent brain computing.

The next generation of aircraft is making a giant leap forward by applying the “cyber”layer in hardware, infrastructures, and humans for enhancing onboard system services and performance. “Cyber”refers to the potent mix of digital computing, storage, software, and data networking.

Legacy networks are now in the process of migrating to new infrastructures that promise to deliver revolutionary services. This article covers the next generation of anytime/anywhere personal communication services, with an emphasis on Internet protocol (IP)-based multimedia subsystem (IMS)-aided infrastructure that relies on the session initiation protocol (SIP).

Ambient intelligence (AmI) is a computing paradigm wherein conventional input and output media no longer exist. Instead, sensors and processors are integrated into conventional objects that harmonize with people in their living situations. AmI relies on artificial intelligence (AI) to perform these duties. It obtains contextual information from embedded sensors, interprets it, and adapts the environment to interpreted needs. The paper provides set of computational methodologies enabling the development of enhanced Aml healthcare applications.

This survey proposes a taxonomy to classify existing topology control issues. It examines topology coverage problems in detail and reviews connectivity problems under spatial and temporal controls. Open issues are presented, and the paper points toward a set of WSN design guidelines and how these would apply to a set of case studies. The purpose of taxonomy is to classify topology control systems in WSNs. Two primary performance metrics are essential: coverage and connectivity.

This paper studies a reconceptualization of radar, how “cognitive radar”can mimic the visual brain. There are three classes of radar to be considered. Traditional radar operates on a feedforward basis. Foreactive radar uses a feedback link connecting the receiver to the transmitter, and it is fully adaptive. Cognitive radar builds on the first two classes by developing rules of behavior (in effect, learning from experience).

Cognitive control is part of a wider framework called cognitive dynamic systems, which builds on a paradigm of cognition composed of five elements: perception-action cycle, memory, attention, intelligence, and language. Any closed-loop feedback control system is based on the perception-action cycle. Adaptive control systems, it can be argued, incorporate the attention and intelligence aspects of the paradigm, but not memory. The language component becomes relevant to a network of cognitive agents. Cognitive control depends on an understanding of the information gap - the distance between relevant information extracted from measurements and the sufficient information that is required. Cognitive control should not be thought of as a replacement system design paradigm; it is additive in nature. It augments state-control paradigms such as adaptive control and neurocontrol. Using cognitive control, we can improve the utilization of computational resources and manage risk more effectively.

This paper surveys the main security threats within cognitive radio networks. Attack techniques are classified by type of attacker, intrusive nodes, and greedy cognitive radios.

To meet the increasing demands on the Internet because of growing video and other new types of media, peer-to-peer (P2P) media streaming is increasingly popular, because it is so eminently scalable. This paper offers a survey of the latest developments in P2P media streaming.

To grasp the challenges and potentials faced, an overview of the fundamentals of recording electrical cell activity is in order. Many types of cells can undergo a transient electrical depolarization and repolarization, triggered by external mechanisms or by intracellular, spontaneous mechanisms. Cells that can generate electrical signals are called electrogenic cells. The most common types of electrogenic cells are brain cells (neurons) and heart cells (cardiomyocytes). The biology of electrogenic cells is complex, a symphonic interdependence of electrical, electrophysiological and biochemical processes. This requires an understanding of mechanisms underlying the functioning of voltage-gated ion channels, the generation of action potentials, and the conduction of action potentials through a cellular network.

Finally, it applies an improved model to generate the most recent (and more relevant) estimates of demand and savings potentials associated with nationwide efficiency improvements using recent data on the installed base of IT devices and efficiency measures in U.S. data centers.
