In a very short time America has realized that global warming poses real challenges to the nation's future. The Agile City engages the fundamental question: what to do about it? Journalist and urban analyst James S. Russell argues that we'll more quickly slow global warming - and blunt its effects - by retrofitting cities, suburbs, and towns. The Agile City shows that change undertaken at the building and community level can reach carbon-reduction goals rapidly. Adapting buildings (39 percent of greenhouse-gas emission) and communities (slashing the 33 percent of transportation related emissions) offers numerous other benefits that tax gimmicks and massive alternative-energy investments can't match. Rapidly improving building techniques can readily cut carbon emissions by half, and some can get to zero. These cuts can be affordably achieved in the windshield-shattering heat of the desert and the bone-chilling cold of the north. Intelligently designing our towns could reduce marathon commutes and child chauffeuring to a few miles or eliminate it entirely. Agility, Russell argues, also means learning to adapt to the effects of climate change, which means redesigning the obsolete ways real-estate is financed; housing subsidies are distributed; transportation is provided; and water is obtained, distributed and disposed of. These engines of growth have become increasingly more dysfunctional both economically and environmentally. The Agile City highlights tactics that create multiplier effects, which means that ecologically driven change can shore-up economic opportunity, can make more productive workplaces, and can help revive neglected communities. Being able to look at multiple effects and multiple benefits of political choices and private investments is essential to assuring wealth and well-being in the future. Green, Russell writes, grows the future. 1. Language: English. Narrator: Brandon Massey. Audio sample: http://samples.audible.de/bk/adbl/014257/bk_adbl_014257_sample.mp3. Digital audiobook in aax.

Model Assisted Survey Sampling

ggf. zzgl. Versand

The book covers the various approaches to modeling the in-cylinder processes such as mixture formation, combustion and formation of exhaust emissions in diesel and gasoline engines. Due to their complexity emphasis is put on multi-dimensional spray, combustion and emission formation models. However, phenomenological as well as zero-dimensional thermodynamic models, which are still widely used in engine development because of their computational efficiency, are addressed as well. Example calculations of each model type are compared with corresponding experimental data ¿ represented in diagrams as well as in images resulting from modern optical measuring techniques ¿ in order to discuss the capabilities of today's simulation models as well as the shortcomings that still exist either because of oversimplifying assumptions or because of insufficient knowledge of the real processes. The reader will be provided with an overview of the most important simulation models describing the in-cylinder processes of internal combustion engines. In addition, suggestions are made about which modeling approach is appropriate for a specific type of problem.Now available in paperback, this book provides a comprehensive account of survey sampling theory and methodology suitable for students and researchers across a variety of disciplines. It shows how statistical modeling is a vital component of the sampling process and in the choice of estimation technique. The first textbook that systematically extends traditional sampling theory with the aid of a modern model assisted outlook. Covers classical topics as well as areas where significant new developments have taken place.

A real-time capable in-cylinder pressure based diesel engine-out PM estimator has been developed. Using the ECU signals and in-cylinder pressure data new variables have been derived and used as inputs for an exponential zero dimensional modeling approach. This approach required little computational effort making the ECU capable of cycle based PM emissions calculation, significantly faster than in real-time. Along with the PM estimator an accurate NOx emissions model has been utilized in a MIMO feedback controller motivated by the gain scheduling concept. Two types of experimental passenger car DI diesel engines, equipped with in-cylinder pressure sensors have been used. Measurements have been taken during steady state and transient operation on engine test benches for development work. Implementation of the emission models and the controller has been done on a test vehicle and tests were carried out on the test track and vehicle test bench. Good correlation between the estimated and measured PM has been achieved for various experiments, not only at steady state operation but also for transient states. Particularly, the model delivers good qualitative results in general, as well as good quantitative results in some regions. PM emission gradients between operating points are represented successfully. The raw emissions controller – despite further need for optimization – has been successful in controlling PM and NOx emissions simultaneously over EGR and pilot injection quantity. Gain scheduling has eliminated the need for an inverse combustion model. EGR and injector actuators were manipulated in a cascaded controller structure where the designed PI controllers altered reference values of the actual EGR and pilot injection quantity controllers that were already present in the system.

The possibility of confinement of photons in a microcavity and excitons in quantum wells opens a way to achievement of the strong light-matter coupling regime with the formation of elementary excitations known as polaritons (exciton polaritons, plasmon polaritons, etc) having hybrid half light half matter nature. This book is devoted to theoretical investigation of several aspects of the exciton-polariton physics, including (i) description of the relaxation dynamics of polaritons in real space and time using the density matrix formalism, (ii) investigation of nonlinear effects in terahertz emission from microvavities, (iii) investigation of the emission spectrum of a quantum dot with broken inversion symmetry embedded in a single-mode microcavity, (iv) investigation of the coupling between a giant plasmonic resonance of a metallic cluster and a cavity mode. The density matrix approach can be applied to two- and one-dimensional systems.Quantum dots and clusters represent zero-dimensional objects. Thus, two-, one- and zero-dimensional objects are considered.

Bachelor Thesis from the year 2010 in the subject Business economics - Miscellaneous, grade: 1,3, European Business School - International University Schloss Reichartshausen Oestrich-Winkel (Real Estate Management Institute), language: English, abstract: At the beginning of 2009, the owner of the Empire State Building unveiled his plan to 'go green'. The world famous skyscraper was completed in 1931 in New York, USA. The Art Deco building is currently in the midst of a $500m renovation, where $100m of these funds are designated for the green initiative. The green renovations are expected to decrease energy expenditures by 38 percent or $4.4m annually (Jonas, 2009). The example of the Empire State Building is not unique, since increased environmental awareness has affected nearly every industry. Companies across all industries and nations have launched green initiatives in order to improve their environmental performance and in response to the expressed concerns regarding their immediate environment. Currently, corporations compete to adopt and implement sustainable policies. Particularly the role of the real estate industry in reducing the environmental burden is considered to be the most important, as this industry is one of the largest emitters of harmful chemical substances and a major user of natural resources (Nelson, 2007, p. i). However, it is not enough to consider only the ecological aspects of real estate. This is because real estate, as a commodity, has an enormous economical impact. Other dimensions including economic and social aspects must also be examined. The term sustainability unites the three relevant dimensions. Over the last 20 years, bringing environmental protection to the same level as economic development and social concerns, sustainability has become a worldwide guiding principle. Sustainable development takes the future of mankind into account (Grunwald & Kopfmu¿ller, 2006, p. 7). In the context of global challenges, sustainability means ensuring the addressing of future generation's needs. In contrast to other industries, the real estate industry has been slow to develop sustainable practices. However, today, the idea of sustainability greatly influences actions and motivations associated with the real estate industry. Efforts to create sustainability in real estate are reflected in the names of a large number of the development of building labels, including Green Buildings, Sustainable Buildings, or Zero Emission Buildings. In Addition, more and more developers, architects, engineers, property owners, and lenders consider sustainability issues when planning, constructing, renovating, or living on property.

Tomorrow`s Energy - Hydrogen, Fuel Cells, and t...

Hydrogen is the most abundant element in the universe. An invisible, tasteless, colorless gas, it can be converted to nonpolluting, zero-emission, renewable energy. When burned in an internal combustion engine, hydrogen produces mostly harmless water vapor. It performs even better in fuel cells, which can be 2.5 times as efficient as internal-combustion engines. Zero-emission hydrogen does not contribute to CO2-caused global warming. Abundant and renewable, it is unlikely to be subject to geopolitical pressures or scarcity concerns. In this new edition of his pioneering book Tomorrow¿s Energy, Peter Hoffmann makes the case for hydrogen as the cornerstone of a new energy economy. Our current energy system is a complex infrastructure, and phasing in hydrogen will take effort and money. But if we consider the real costs of fossil fuels--pollution and its effects, international tensions over gas and oil supplies, and climate change--we would be wise to promote its development.
