A solar-based power supply system, such as a Photovoltaic-diesel-battery system, is a particularly attractive option for decentralised power supply in southern Africa where solar radiation is ubiquitous in most countries. Such systems can make a positive contribution to the sustainability of rural communities in developing countries that do not have access to electricity grid as they address shortfalls of stand- alone systems. However, a lot more design effort and expertise is required for optimising the sizing and operational strategy of the PV-diesel-battery hybrid system than is required for single-source systems. This book presents the development and application of a simple spreadsheet-based mathematical model for sizing and...

The increased interest in wireless network design and cross-layer design require an accurate and efficient physical layer model especially when a large number of nodes are to be studied and building the real network is not possible. For analysis of upper layer characteristics, a simplified physical layer model has to be chosen to model the physical layer otherwise the analysis will be too complicated and thus become intractable. In this dissertation, the widely used two-state Markov model is studied and shown to be deficient in many scenarios. Improved two-state run length model and four-state Markov model are designed and demonstrated to achieve accurate network results. Furthermore, the parameters of the proposed models can be set up...

With the development of new laser sources, fiber amplifiers, and other optical components, optical communication systems have undergone enormous growth and evolution in recent decades. The current trend of optical networking is to move towards dynamic, all-optical networks. In all-optical networks, information signals are transmitted from source to destination totally in the optical domain, without the usual optical-electrical-optical conversions at intermediate nodes. New challenges and opportunities emerge in different layers of the optical network architecture in this transition process. This book explores several interesting topics in both the physical layer and the network layer of all-optical networks. Our studies examine physical...

By the Langmuir-Blodgett (LB) technique, films of precise thickness and controlled molecular architecture and order can be obtained. In spite of the large number of applications of LB films, unreliability and slow film deposition speed, problems that can be traced back to the inability to control the nature of the liquid flow field near the vicinity of the moving contact line, have hampered the potential industrial applications of the LB technique. In this book, the deposition of LB films, based on a hydrodynamic model that includes the effect of molecular and double layer forces, is presented. Experimental characterization of the monolayer and multilayer deposition process by relating transfer ratios (TR) to dynamic contact angles,...

High Quality Content by WIKIPEDIA articles! Physical security describes both measures that prevent or deter attackers from accessing a facility, resource, or information stored on physical media and guidance on how to design structures to resist various hostile acts. It can be as simple as a locked door or as elaborate as multiple layers of armed Security guards and Guardhouse placement. Physical security, by no means, is a modern phenomenon. Physical security, as a field, exists in order to deter persons from entering a physical facility. Thus, as long as the need to defend physical facilities has existed, a need to provide for their security has also been needed. Historical examples of physical security include city walls, moats, booby...

With the explosive growth in demand for wireless services, the next generation wireless networks are expected to provide solutions to cost-effective, ubiquitous, always-on broadband access. There has been a general consensus that developing network-level solutions that take advantage of the interplay between the physical-layer and the upper protocol layers would yield significant performance gains. Thus motivated, a common thread of this book is to study physical- layer aware control and optimization in stochastic wireless networks. Specifically, we want to obtain a fundamental understanding of the following issues: How can we take advantages of rich diversities such as time/multi-user/multi-channel degrees of freedom in wireless...

The Pickens Plan is an energy policy proposal announced July 8, 2008 by American businessman T. Boone Pickens. Pickens wants to reduce American dependence on imported oil by investing approximately US$1 trillion in new wind turbine farms for power generation, which he believes would allow the natural gas currently used for power generation to be shifted to fuel CNG trucks and other heavy vehicles. Pickens thinks that his plan could reduce by $300 billion (43%) the amount the country spends annually on foreign oil. Данное издание не является оригинальным.

A pickup device acts as a transducer that captures mechanical vibrations, usually from suitably-equipped stringed instruments such as the electric guitar, electric bass guitar or electric violin, and converts them to an electrical signal which can then be amplified, recorded and broadcast.A magnetic pickup consists of a permanent magnet such as a AlNiCo, wrapped with a coil of a few thousand turns of fine enameled copper wire. The pickup is most often mounted on the body of the instrument, but can be attached to the bridge, neck and/or pickguard, as on many electro-acoustic archtop jazz guitars and string basses. The vibration of the nearby soft-magnetic strings modulates the magnetic flux...

A pickup truck (or pick-up truck or simply pickup) is a light motor vehicle with an open-top rear cargo area (bed) which is almost always separated from the cab to allow for chassis flex when carrying or pulling heavy loads. Several North American vehicles, the Chevrolet El Camino, Ford Ranchero, and Honda Ridgeline and Subaru Baja have beds, but are not technically trucks. Although the El Camino and the Ranchero were built with body-on-frame architectures, they were based on existing station wagon platforms, while the Ridgeline uses a spot welded sheet steel monocoque (unibody) chassis in the same style as modern passenger cars. Trucks typically have either a tubular or channel rail chassis with a fully floating cab and separate cargo...

A picocell is wireless communication system typically covering a small area, such as in-building (offices, shopping malls, train stations, etc.), or more recently in-aircraft. A picocell is analogous to a WiFi access point. In cellular wireless networks, such as GSM, the picocell base station is typically a low cost, small (typically the size of a sheet of A4 paper and about 2-3 cm thick), reasonably simple unit that connects to a Base Station Controller (BSC). Multiple picocell 'heads' connect to each BSC: the BSC performs radio resource management and hand-over functions, and aggregates data to be passed to the Mobile Switching Centre (MSC) and/or the GPRS Support Node (GSN).

High Quality Content by WIKIPEDIA articles! The term picotechnology is a neologism intended to parallel the term nanotechnology. It is a hypothetical future level of technological manipulation of matter, on the scale of trillionths of a meter (10?12). This is approximately three orders of magnitude smaller than a nanometer (and thus most nanotechnology) and two orders of magnitude smaller than most chemistry transformations and measurements. Basically picotechnology would be the manipulation of matter at the sub-atomic level. Engineering at this scale would involve working directly with the finest known or theorized structures of matter, such as strings and quarks. Данное издание не является...

Pierre Lallement, is considered by some to be the inventor of the bicycle. As a 19-year-old maker of baby carriages in Nancy, France in 1862, Lallement saw someone ride by on a dandy horse. Rather than build one of his own, he added a transmission comprising a rotary crank mechanism and pedals attached to the front-wheel hub, thus creating, allegedly, the first true bicycle. He moved to Paris in 1863, apparently interacted with the Olivier brothers, who saw great commercial potential in his invention. Данное издание не является оригинальным. Книга печатается...

PZT Ceramic: Most of the development of piezoelectric ceramics has been focused on producing new materials which have the dielectric and piezoelectric properties required for use in the desired piezoelectric ceramic devices. The vast majority of these materials found in the marketplace today are lead zirconium titanate (PZT) which have a perovskite structure, and are characterized by high dielectric constant, low dielectric losses, and high electromechanical coupling factors. The objective of this book was to produce the piezoelectric ceramic (PZT) materials using solid-state reaction and sol- gel techniques to obtain a homogenous structure and high purity materials. By examining the different properties of PZT ceramic materials this...

Power electronic circuits have traditionally been based on magnetic technology, and until recently, have not been part of the tide of miniaturization and integration advances from which signal- processing integrated circuits have benefited. In an effort to miniaturize power components piezoelectric, rather than magnetic transformer could be employed in the power supplies. Utilization of piezoelectric transformers in power electronics became possible since new piezoelectric materials have recently been grandly developed that exhibit improved piezoelectric ceramic characteristics. In the past few decades, piezoelectric transformers have been developed and used widely in many applications, such as DC/DC converters, adapters, and electronic...

Prazisionsmessgerate wie beispielsweise Oberflachenmessgerate, verlangen einen extrem hohen Standart an Fuhrungsgenauigkeit. Herkommliche Gleitlager bringen in Abhangigkeit ihrer Einsatzdauer einen Verschleiss mit sich. Es ist also naheliegend, eine kontaktlose Fuhrung zu konstruieren, um von Oberflachen unabhangig zu sein. Eine Losung dafur ware das reibungsarme Luftlager. Die Nachteile beider Hauptarten dieser Lagerart sind jedoch nicht vernachlassigbar: Statische Luftlager benotigen eine externe Druckluftquelle, was zu einem unhandlichen und teuren Zusatzsystem fuhrt; dynamische Luftlager arbeiten nur mit hohen Geschwindigkeiten, die zur Abnutzung wahrend der Start- und Stopphasen fuhren. Ausserdem bringt das Standartluftlager den...

A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. Данное издание не является оригинальным.
