Destruction effect on passengers in case of road traffic accident was decreased especially using deformation zones optimization and restraint system application. There is still significant reserve in solid barriers aggressiveness reduction. The danger can be demonstrated by stiffness and firmness of the barrier which effect impact hardness. From statistical point of view represent accidents with solid barriers one sixth of all accident in certain year, but they are more serious because of one fourth of all traffic accident victims. Solid barriers can be represented by drainage ditch culvert face. The access bridge is not usually conspicuous enough near the traffic lane so the driver can ditch and crash this barrier in case of exceptional situation such as avoidance manoeuvre. This work deals with the technical solution of access bridges with integrated deformation zone.

Basically, the missile, is described as a weapon or object capable of being thrown or projected so as to strike a distant object. One distinction between a missile and an airplane is that, unlike an airplane, a missile is usually expendable in accomplishment of its mission. ····· 1036121210
für 74.61€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The book aims at providing the unique information on friction welded products of dissimilar metals of Aluminum alloy and stainless steel which has wide range of applications. Aluminum alloys are attractive due to their lower weight, corrosion resistance, superior recycling ability and good workability. Due to these properties Stainless steels - Aluminum joints are widely replacing conventional stainless steel products in many important areas like spacecraft, cryogenic applications, chemical plants and high vacuum systems. In the presentation of this book major emphasis has been laid on the combination of dissimilar metals of Aluminum Alloy and Stainless steel to produce a weldment that meets the intended service conditions. Although the joint strength and acceptance tests are essential for welded products, and also service conditions such as Thermal cycling and Corrosive environment encountered during service are also equally important.

The inadequate roads and crowded cities warrant the need for compact luxurious cars. Aerodynamics plays a major role in the fuel economy of a car and the styling needs to be constrained with aerodynamics. In the present work, a user survey was conducted to understand the target customer, followed by a CFD analysis of the Swift to understand its flow behaviour. Concepts were created based on the data from both sources. CFD analysis carried out on the Xite concept returned CD and CL values which were higher than the Swift. Modifications were made to improve the flow. The modified Xite owing to its improved drag and lift over the standard Xite was chosen for final detailing and customisation. From the present work, it was concluded that a huge potential existed for premium compact cars with sporty traits for the urban users with most users users wanting a car to make a style statement and for exclusivity. Improvements in aerodynamic performance were also observed. ····· 1036119609

An in-depth database containing information on 512 real world vehicle crashes was constructed. The study identifies the characteristics of the collisions and occupant spinal injuries in Saudi Arabia, and suggests measures to mitigate them. A logistic model has been presented which can be used to provide information about the crashes and spinal injuries. State of the art techniques for accident reconstruction have been demonstrated to mitigate the severity of the accidents and resulting spinal injuries. Computational simulations have been demonstrated to simulate spinal injuries in various vehicle crashes. The knowledge from this study can be used to better understand the injury mechanics behind spinal injuries, and to develop measures to aid in the identification of safety issues such as roadway design, human factors, vehicle design and crashworthiness related to occupant protection from spinal injuries. ····· 1036119444
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Civil aviation is a highly protected industry where the impact of the economic globalisation is invisible. National control over foreign ownership and control over cabotage restricted this industry to become a fully globalised industry. Based of the theory of economic liberalisation, in 2007 The European Commission, had coined in the idea of a establishing a transatlantic open aviation area (OAA) where there will be no- control over foreign ownership and control and over cabotage. The EC argues that the transatlantic OAA would liberalise the 60% of global civil aviation. Both sides of Atlantic strikes the first phase of two phased agreement. This book analysed the historical phases of civil aviation and gradual changes that happened over the times in the EU and the US civil aviation industry. In the context of first phase agreement main objective of this book is to examine the agreement and its potential possibility to become a successful model for a globalised civil aviation industry. ····· 1036118487
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Conventional gasoline engines work on the fixed compression ratio which is a golden mean between the knocking at high loads and fuel economy at low loads. A variable compression ratio engine can work at various compression ratios depending upon the vehicle performance needs. Engine downsizing, great fuel economy, no knocking operation and flexibility in fuel used make them a brilliant choice as automotive engines in near future. However the VCR engines also suffers from disadvantage of mass manufacturing due to their complexity. The author of the present book studied the details of VCR engines and proposed a concept of conversion of fixed compression ratio in to a variable compression ratio engine. The newly designed mechanism makes use of a split type of cylinder block which varies the compression ratio by lifting the cylinder head. The mechanism can be loaded on two stroke as well as four stroke engines. Mechanical simplicity, improved fuel economy and increase in the brake thermal and volumetric efficiency are the major advantages after conversion of fixed compression ratio engine into a variable compression ratio engine. ····· 1036118459

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Optimization of ship routes is an important consideration in maritime industry. By application of optimal control theory in conjunction with hydrodynamics and weather forecasting tools, most economical and safe route can be charted. Although a large volume of work is available addressing the ship-weather-routing problem. But most of them appear to concentrate on theoretical development related to the algorithm rather than the algorithm itself. The possible reason for limited detail on the actual algorithm that is used by ship navigators may be the commercial and proprietary nature of such algorithm. Also these works do not provide any optimized sea-routes but only solutions to the idealized problems. This work focuses on development of a practical ship routing algorithm which can be used by ship navigators using on-board computers during a voyage, and routing decisions can be made as the voyage progresses. I hope the detailed and practical oriented nature of this book will be helpful for readers to gain better insight in marine navigation. ····· 103613422
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Good ride performance is one of the most important key attribute of a passenger vehicle. One of the methods to achieve this is by using continuously variable transmission (CVT). This is because a CVT has the capability of providing an almost infinite ratio within its limits smoothly and continuously. In this thesis, the work focuses on developing an intelligent control system that will provide the appropriate CVT ratio based on a vehicle maximum power driving strategy. This will provide maximum acceleration performance at all time during driving. On-line values of the engine speed and throttle opening are used as inputs to the developed intelligent controller, which then will provide the appropriate required CVT ratio for the vehicle to perform accordingly. An electromechanical dual acting pulley CVT designed (EMDAP-CVT)and developed by the Drivetrain Research Group (DRG) UTM, is used in this work. EMDAP-CVT with zero belt misalignment give a great performance and longer belt life. Adaptive artificial neural network (AANN) is then applied as intelligent controller and the results show that the intelligent controller using AANN performs satisfactorily. ····· 103613184· 1 ·· 2 ·· 3 ·· 4 ·· 5 ·· 6 ·· 7 ·· 8 ·· 9 ·
