  • This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location.

  • The previous edition of Energy Technology Perspectives(ETP), published in summer 2008, called for an energy technology revolution to tackle the undesirable consequences of our current patterns of energy supply and use. It also highlighted that, if we did not alter course, concerns about energy security and the threat of dangerous climate change would only become much worse. So what – if any – progress have we made over the last two years in meeting these challenges? At first sight, it may seem as though not much has changed.

  • China is rapidly developing as evidenced by enhanced urbanization and industrialization and greatly increased energy consumption. However, these have brought Chinese cities a variety of urban air pollution problems in recent decades. During the 1970s, black smoke from stacks became the characteristic of Chinese industrial cities; in the 1980s, many southern cities began to suffer serious acid rain pollution; and recently, the air quality in large cities has deteriorated due to nitrous oxides (NOx), carbon monoxide (CO), and photochemical smog, which are typical of vehicle pollution.

  • Explosives and propellants contain considerable chemical energy that can be converted into rapid expansion. In contrast to the simple burning of a fuel, explosives and propellants are self-contained and do not need an external supply of oxygen via air. Since their energy content inherently creates the risk of accidental triggering of the explosive reaction, the correct synthesis, formulation, and handling during production and use are of utmost importance for safety, necessitating specialist knowledge on energetic materials, their characteristics, handling and applications.

  • In this chapter, we will find out how to get the most solar energy out of the sun by considering the time, the altitude angle, the radiation and the photovoltaic (PV) materials. A simple PV model helps to understand the mechanism of energy conversion - solar to electricity. We will further use a simple equivalent circuit to represent a PV cell to investigate its current-voltage characteristics.

  • Thermodynamics is an aspect of physics which deals with the energy characteristics of materials and with the behavior of systems undergoing changes in system energy levels. The field of thermodynamics is quite broad as well as deep, and can vary in presentation and in application from relatively simple to very complex. For the purposes of this book, a relatively simple presentation is adequate.

  • In this chapter, we will discuss a more accurate equivalent circuit for a PV cell. This circuit helps us to have better prediction and understanding of PV cell current-voltage characteristics as well as at different types of load connected to the PV panel, which is made up of an array of PV cells. Later in this chapter we will discuss the concept of maximum power point tracker (MPPT).

  • Virtual Reality (VR) and Augmented Reality (AR) tools and techniques supply virtual environments that have key characteristics in common with our physical environment. Viewing and interacting with 3D objects is closer to reality than abstract mathematical and 2D approaches. Augmented Reality (AR) technology, a more expansive form of VR is emerging as a cutting-edge technology that integrates images of virtual objects into a real world.

  • In the early 1970s, it was clear that the world economy was facing recession and that the four-fold increase in crude-oil prices by OPEC, a monetary crisis, and inflation were the main reasons for such a trend. The four-fold increase in crude-oil prices in 1974, which was intensified in 1979, is why 1974 and 1979 are called the years of “the first” and “the second crude-oil shock”, respectively. Increases in crude-oil prices had an effect on all importing countries, more precisely on their economic development.

  • Since the First International Congress on Liquid Crystals (Lcs), held at Kent State University, OH, USA, in 1965, the implications of these systems associated with various aspects of telecommunications, laser, display, automobile, aerospace technologies, thermo-optics, medicine and biology have been the subject of considerable debate among researchers, scientists and engineers. Indeed, LCs, being a unique mesomorphic phase of matter, combine properties of both solids (long-range orientation order, manifestations of Bragg diffraction, etc.) and liquids (fluidity, viscosity, etc.).

  • The most important fact related with fluid motion is to understand the fluid patterns, and the flow structure ‐ vortices, recirculation zones, high mix regions, poor mix regions, calm regions, to name a few. Moreover, most of the flows have turbulent characteristics and turbulence remains one of the unsolved problems in physics. No one knows how to obtain stochastic solutions to the well‐posed set of partial differential equations that govern turbulent flows.

  • Recently, several solutions to the robot localisation problem have been proposed in the scientific community. In this chapter we present a localisation of a visual guided quadruped walking robot in a dynamic environment. We investigate the quality of robot localisation and landmark detection, in which robots perform the RoboCup competition (Kitano et al., 1997). The first part presents an algorithm to determine any entity of interest in a global reference frame, where the robot needs to locate landmarks within its surroundings.
