Model Assisted Survey Sampling
85,01 € *
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.

An electric car is often referred to as an electric vehicle or EV. In Select Your Electric Car, I explore the various options of EVs available in the United States. If you live in California or in one of the other states which have similar zero emission vehicle standards, you will have more choices. These states have laws that car companies selling cars in their state must provide a certain percentage of EVs. I am going to focus on the EVs which are widely available in the US now (2018). I’ll compare them, so that hopefully you will be able to purchase the EV which fits your lifestyle - or the lifestyle which you plan to adopt once you own an EV. I’ll also look at a few other EVs which are not as widely available.In 2019, car dealers will be offering more models of EVs nationally, at least that’s the plan. I’m thinking that you might want a car with more of a track record. So I won’t be saying as much about those models, though I will mention them.The US ranks seventh in number of EVs sold, following China, United Kingdom, France, Sweden, Netherlands, and Norway who is at number one. If you wanted to wait until 2019 to drive your EV, and you had 200,000 dollars to spare, and you had a commercial driver’s license (CDL) or could hire a driver who did; why not just purchase a Tesla Electric Semi. After all, Elon Musk is now saying it will have a 600-mile range. Even if he’s only 75 percent correct, that’s still a 450-mile range. I could drive into town (Olympia) every day of the week and up to the big city (Seattle) on the weekend. And I still wouldn’t have to charge my rig. And in Aug 2018, a Tesla Semi made it from Coast to Coast across the US. It did have to be recharged. But the driver was able to find charging stations which were powerful enough to charge it. But where would I park the thing? Besides I don’t have a CDL. And the few people I know who do aren’t interested in being my personal chauffeur. I also definitely don’t have 200,000 do 1.

W and Z Bosons
29,00 € *

High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! The W and Z? bosons are the elementary particles that mediate the weak force. Their discovery has been heralded as a major success for the Standard Model of particle physics. The W particle is named after the weak nuclear force. The Z particle was semi-humorously given its name because it was said to be the last particle to need discovery. Another explanation is that the Z particle derives its name from having zero electric charge. All three types have a spin of 1. The emission of a W+ or W? boson either raises or lowers the electric charge of the emitting particle by 1 unit, and alters the spin by 1 unit. At the same time a W boson can change the generation of the particle, for example changing a strange quark to an up quark. The Z boson cannot change either electric charge nor any other charges (like strangeness, charm, etc.), only spin and momentum, so it never changes the generation or flavour of the particle emitting it.

The planar solid-oxide fuel cells (PSOFCs) have emerged as one of the promising candidates for future energy system because of their high energy efficiency, fuel flexibility, zero emission, modularity and high tolerance to the fuel impurities.However, for large-scale commercialization of the PSOFC technology, there is a strong need of developing a reliable and highly efficient PSOFC power system. Development of such a reliable PSOFC based power system requires knowledge of the several feedback effects from the power electronics system and the application loads that may impact the PSOFC stack and the system as a whole. Therefore, it is important to develop analytical methodologies to investigate and mitigate the effects of these electrical feedbacks on the performance of PSOFC systems.On the whole, the dissertation focuses on i) the modeling and development of an effective PSOFC power-system design and system interaction analyses, ii) cost-constrained PES topology design for PSOFCS and iii) the design of cost effective optimal controller and controlling strategy for mitigation of electrical impacts with higher system efficiency.

Emerging New Product Development
44,90 € *

New competitive pressures are unsettling traditional carmakers. These include: new consumer groups in emerging markets, zero emission requirements, new competitors from emerging markets, and increasing dependency on suppliers. These pressures require carmakers to react more rapidly while designing new vehicles. New product development is the core process used to develop synergy between customer requirements and the objectives of the carmakers to produce successful automobiles. This has served carmakers well during an era of relatively stable competition with easily recognizable technologies and competitors. In a new area, where technologies are changing rapidly and new competition is emerging, there is a need for a new approach to new product development. A review of existing innovation patterns of both traditional and emerging carmakers has led to the development of an emerging methodology that consists of concept, design and validation phases. A case study based approach focusing on Chinese and German carmakers shows their distinct strategies. The emerging new product development methodology allows carmakers to better cope with changing requirements in the industry.

In this modern era, people have become such dependent on motorized transportation that they want to have their private mode of transport for the convenience of their frequent movement. From a recent statistics it is found that currently almost 2.7 million vehicles are running alone on the roads of Bangladesh and approximately 2.4 million are the type of vehicle which is used for personal means. Because of the huge number of vehicles on the road, the fuel consumption is very high and except gas, most of other fuels (octane, petrol, diesel etc.) are imported from abroad. Bangladesh an import-dependent country, with this high demand of fuel, is so now counting loss. Furthermore burning of these fuels causes a huge amount of carbon dioxide (CO2) emission that results greenhouse effect.In this project, the idea of a green bus system is proposed which can be a remarkable aid to the recent traffic condition. In this regard a prototype of green bus system is implemented where resources such as wind, solar and piezo-electric generator are employed. All the resources being used in this project are abundantly available and also emit zero CO2.

General Motors EV1

The General Motors EV1 was an electric car produced and leased by the General Motors Corporation from 1996 to 1999. It was the first mass-produced and purpose-designed electric vehicle of the modern era from a major automaker, and the first GM car designed to be an electric vehicle from the outset. The decision to mass-produce an electric car came after GM received a favorable reception for its 1990 Impact electric concept car, upon which the design of the EV1 drew heavily. Inspired partly by the Impact's perceived potential for success, the California Air Resources Board subsequently passed a mandate that made the production and sale of zero-emission vehicles a requirement for the seven major automakers selling cars in the United States to continue to market their vehicles in California. The EV1 was made available through limited lease-only agreements, initially to residents of the cities of Los Angeles, California and Phoenix and Tucson, Arizona.
