The study is focused on improvisation on performance of the rear axle of heavy vehicles such as trucks, tractors, trailers, buses and other heavy vehicles subjected to loading more than designed load carrying capacity. Primary objective is to reduce the weight of the entire axle assembly so as to increase the efficiency of the system and reduce the material cost of the axle assembly. Since the vehicles are subjected to loading more than the designated capacity, secondary objective is to improve the stress distribution as a result of excessive loading and effective measures to increase the weight carrying capacity. The base design solid model is subjected to real loading conditions for steady state static analysis. Post analysis the model is subjected to topology optimisation simulation, the results of which are referred for determination of critical area, methods and possible modifications in the geometry and areas where addition or removal of material will optimise the design. Multiple modification in geometry and material assignment has brought up a lighter, efficient, stronger and cost effective model for the rear axle of a heavy vehicle.

Estimation of Bluff Body Transient Aerodynamic ...

A method for the estimation of transient aerodynamic data from dynamic wind tunnel tests has been developed and employed in the study of the unsteady response of simple automotive type bodies. The experimental setup consists of the test model mounted to the oscillating model facility such that it is constrained to oscillate with a single degree of freedom of pure yawing motion. The yaw position is recorded from a potentiometer and the time response provides the primary measurement. Analysis of the wind-off and wind-on response allows the transient aerodynamic loads to be estimated. The frequency of oscillation is modified by altering the mechanical stiffness of the facility. The transient results are compared with a quasi-steady prediction based on conventional tunnel balance data and presented in the form of aerodynamic magnification. The facility and analysis techniques employed are presented and the results of a parametric study of model rear slant angle and of the influence of C-pillar strakes is reported. The results are strongly dependent on shape but for almost all rear slant angles the results show that the transient response exceeds the steady state data.

The rapid development of novel solar cell concepts requires an accurate and reliable modeling to obtain a better physical understanding of the solar cells, as well as to reduce the number of time consuming and expensive experimental investigations. In order to get a rough overview about industrially relevant silicon solar cell concepts in production and their efficiency potential an overview over different solar cell architectures is presented at the beginning of the work.For a higher accuracy of the numerical simulations of silicon solar cells, the effect of free carrier absorption is discussed in detail. Also, an advanced method for precise modeling of highly aluminum-doped p+ silicon is presented. By using this method, a detailed analysis on the optimization of n+np+ silicon solar cells with aluminum-alloyed rear p+ emitter for industrial applications is shown. As a high-efficiency approach, lateral conductance effects of locally contacted rear surface passivated p-Si solar cells are investigated. Furthermore, a future orientated solar cell concept, bifacial monocrystalline Si solar cells have been optimized for upconversion applications via numerical simulations.

This expanded second edition presents the fundamentals and touchstone results of real analysis in full rigor, but in a style that requires little prior familiarity with proofs or mathematical language.The text is a comprehensive and largely self-contained introduction to the theory of real-valued functions of a real variable. The chapters on Lebesgue measure and integral have been rewritten entirely and greatly improved. They now contain Lebesgue's differentiation theorem as well as his versions of the Fundamental Theorem(s) of Calculus.With expanded chapters, additional problems, and an expansive solutions manual, Basic Real Analysis , Second Edition is ideal for senior undergraduates and first-year graduate students, both as a classroom text and a self-study guide.Reviews of first edition:The book is a clear and well-structured introduction to real analysis aimed at senior undergraduate and beginning graduate students. The prerequisites are few, but a certain mathematical sophistication is required. ... The text contains carefully worked out examples which contribute motivating and helping to understand the theory. There is also an excellent selection of exercises within the text and problem sections at the end of each chapter. In fact, this textbook can serve as a source of examples and exercises in real analysis. -Zentralblatt MATH The quality of the exposition is good: strong and complete versions of theorems are preferred, and the material is organised so that all the proofs are of easily manageable length, motivational comments are helpful, and there are plenty of illustrative examples. The reader is strongly encouraged to learn by doing: exercises are sprinkled liberally throughout the text and each chapter ends with a set of problems, about 650 in all, some of which are of considerable intrinsic interest. -Mathematical Reviews [This text] introduces upper-division undergraduate or first-year graduate students to real analysis.... Problems and exercises abound, an appendix constructs the reals as the Cauchy (sequential) completion of the rationals, references are copious and judiciously chosen, and a detailed index brings up the rear. -CHOICE Reviews

Visual Paranoia in Rear Window, Blow-Up and The...

Against the backdrop of recent postmodern discourse on cultural theory, Eva Schwarz provides a gripping analysis of the concept of what she describes as visual paranoia. Her study is based on a detailed analysis of three films: Alfred Hitchcock s Rear Window (USA, 1954), Michelangelo Antonioni s Blow-up (GB, 1966) and Peter Weir s The Truman Show (USA, 1998). The starting point of all three analyses is the representation of the postmodern media and information age as an incisive culture of the visual, which coincides with the general socio-political trend of cultural paranoia, the roots of which are to be found in American politics and society of the late 1940s and which has since permeated Anglo-American culture.The discourse on the truthfulness of images, the reality of visual representations and the visual as such forms the context out of which the theory of the development of visual paranoia arises. While other paranoia films, usually thrillers or science fiction films, concern themselves with the sociopolitical manifestation of cultural paranoia, the three films chosen for Schwarz's study focus on the fundamental crisis of the visual as such, from scopophilic paranoia in Rear Window to photographic paranoia in Blow-Up, culminating in the scopophobic manifestation of visual paranoia in The Truman Show.The once valid saying, "seeing is believing", can no longer be taken for granted. In postmodern times, the visual cannot be trusted any more.
