Abstract

Exploring how to counteract the world's energy insecurity and environmental pollution, this volume covers the production methods, properties, storage, engine tests, system modification, transportation and distribution, economics, safety aspects, applications, and material compatibility of alternative fuels. The esteemed editor highlights the importance of moving toward alternative fuels and the problems and environmental impact of depending on petroleum products. Each self-contained chapter focuses on a particular fuel source, including vegetable oils, biodiesel, methanol, ethanol, dimethyl ether, liquefied petroleum gas, natural gas, hydrogen, electric, fuel cells, and fuel from nonfood crops.

Abstract

Urban heat islands are a new type of microclimatic phenomenon that causes a significant increase in the temperature of cities compared to surrounding areas. The phenomenon has been enforced by the current trend towards climate change. Although experts consider urban heat islands an urgent European Union public health concern, there are too few policies that address it. The EU carried out a project to learn more about this phenomenon through pilot initiatives. The pilots included feasibility studies and strategies for appropriately altering planning rules and governance to tackle the problem of urban heat islands. The pilots were carried out in eight metropolitan areas: Bologna/Modena, Budapest, Ljubljana, Lodz, Prague, Stuttgart, Venice/Padova, and Vienna. The feasibility studies carried out in these pilot areas focused on the specific morphology of EU urban areas, which are often characterised by the presence of historical old towns.

Abstract

Heat exchange processes in steady flows have been studied extensively over the last two hundred years, and are now a part of undergraduate syllabi in most engineering courses. However, heat transfer processes in oscillatory flow conditions are still not very well understood. Their importance is well recognized in applications including Stirling machines, thermoacoustic engines, and refrigerators or pulsed-tube coolers in cryogenics. Additionally, the enhancement of heat transfer by using oscillatory, and, in some cases, pulsating flows is important in many areas of mechanical and chemical engineering for the intensification of heat transfer processes and possible miniaturization of heat exchangers of the future. This Special Issue was intended as a dissemination platform for researchers working in the field to have an opportunity to consolidate recent advances in this important research area. All types of research approaches were invited, including experimental, theoretical, computational fluid dynamics (CFD), and their combinations, while the approaches could be either of a fundamental or applied nature. The guest editor and the editorial team of Applied Sciences hope that the readership will find the selection of ten articles presented here a useful contribution to the emerging field of heat transfer processes in oscillatory flow conditions.

Abstract

The firms and markets of today's complex socio-economic system developed in a spontaneous process termed evolution, in just the same way as the universe, the solar system, the Earth and all that lives upon it. Darwin's theory of evolution clearly demonstrated that evolution involved increasing organization. As we began to explore the molecular basis of life and its evolution, it became equally clear that it depended on the processing and communication of information. This book develops a consistent theory of evolution in its wider sense, examining the information based laws and forces that drive it. Exploring subjects as diverse as economics and the theories of thermodynamics, the author revisits the paradox of the apparent conflict between the laws of thermodynamics and evolution to arrive at a systems theory, tracing a continuous line of evolving information sets that connect the Big-Bang to the firms and markets of our current socio-economic system.
