In particular, problems of planning of self-reconfiguration received considerable attention. Problems of reconfiguration planning play a central role for modular reconfigurable robots. Solutions for such problems lies at the heart of any control system of modular reconfigurable robots. Performance of such solutions is the base factor for the performance of the whole control system of modular reconfigurable robot. Recently, the optimal reconfiguration planning problem of finding the least number of reconfiguration steps to transform between two configurations for chain-type modular robots was introduced. It is preferred that the robot keeps connected throughout the reconfiguration process. Respectively, in this book we suppose that the robot keeps connected throughout the reconfiguration process. We describe an approach to solve the problem. Our approach is based on constructing logical models for considered problem. Also we consider genetic and local search algorithms for the problem. The book should be especially useful to professionals in modular robotics. ····· 1036125674

This is done by considering n ( 2), d-dimensional oscillators each with an assymptoticaly stable limit cycle coupled by a nearest neighbour linear diffusive like path. In chapter two we review what has been done in relation to the three aspects namely synchronization, stability and persistence of the synchronized manifold. In Chapter three, we state and prove a theorem that gives the conditions for stability and persistence of the synchronized state. Here we give the equations that describe the nature of dynamics of coupled oscillators and a detailed analysis where Invariant manifold Theory and Lyapunov exponents are used to establish the range of coupling strength for stability and robustness of synchronized state. The book is of great value to the fields of both Applied Mathematics and Statistics. ····· 1036125665

This subgroup was introduced in 1958 by H. Wielandt. GAP provides a programming language and a library of thousands of functions written in GAP language to implement the algorithms on Group Theory. Since 1992, many user contributed programs called Packages have been distributed by GAP. This book is also an effort to contribute to Computational Group Theory as GAP Package. These algorithms helps to compute the various Wielandt subgroups and series of a finite group G, like Wielandt, Generalized Wieladnt, Strong Wielandt, pWielandt, and pStrong Wielandt subgroups and series of a finite group G.

The topological spaces (X, ) and (X, ) have the same family of Sw-open sets.The concept of Sw-compactness is introduced and we prove that a space X is Sw-compact if and only if for every somewhat preopen cover of a space X there is a finite subcover under the condition that X is strongly irresolvable.Separation axioms are defined and characterized and it is proved that the space X is Sw-T2 whenever each point of X possesses an Sw-regular subset which is an Sw-T2 subspace in X. ····· 1036125471

Hearing the word default one can imagine the biggest defaults in the history of economy like that of Lehman Brothers in 2008. However, the exact definition of a default explains it only as a failure to meet debt obligations such as loans or bonds. The debtor is in default when he is either unable or unwilling to pay the debt. One has to distinguish the default from a state of being unable to pay the debts precisely which is called insolvency. The company is insolvent when it is unable to pay debts as they fall due (cash flow insolvency) or when the liabilities exceed the assets (balance sheet insolvency). It is worth mentioning that the insolvency can lead to a bankruptcy which is the process of legally defining a financial situation as insolvent. While modelling credit risk, one usually takes under consideration the company s default in general, without looking into the causes and hence distinguishing between being unable or unwilling to pay the debts. ····· 1036125444

Thus in recent years, intelligent optimization techniques have been a growing interest for solving such complex problems. They model some natural phenomena, based on the principle of evolution (survival of the fittest). They are able to handle problems, which have special features such as discontinuities, multimodality, and disjoint feasible spaces, and any other real complex problems we focus on how intelligent optimization techniques solve multistage decision making problems. ····· 1036125379

These problems are often described by differential equations where the highest order derivative is multiplied by an arbitrarily small parameter` `known as the singular perturbation parameter. The solution of these problems possesses boundary (or interior) layers which are thin narrow regions in the neighborhood of the boundary (or interior) of the domain, where the gradient of the solution becomes very high as goes to zero. Classical numerical schemes fails to yield satisfactory numerical approximations on uniform grids due to the presence of boundary layers. To solve SPP, fitted mesh methods are often followed which comprise of standard finite difference operators on specially designed meshes. The aim of this book revolves around developing, analyzing and optimizing the -uniform upwind based fitted mesh methods resolving the convection-dominated layer type problems using non uniform grids. ····· 1036125108

Simple data dependent constraints are derived on the free parameters in the description of rational bi-quadratic spline function to preserve the shape of 3D data. The developed scheme is economical to compute and visually pleasant, it also gives the extra freedom to the user to refine the shape of the surface as desired.

····· lezzter Preis 53.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The growth of technology has placed rather severe demands on materials engineers to come up with novel materials at low cost to meet stringent and often contradictory property requirements which conventional materials cannot satisfy. In this respect,composite materials show great promise because of their superior stiness, high strength at elevated temperatures and better creep characteristics. Starting as early as 1906 the rotating isotropic disc has been studied by Grubler (1906)followed by Donatch (1912). Probably the first recognition given to the industrial importance of creep was by Dickenson in 1922. Experimental studies have demonstrated that steady state creep rate in aluminum or its alloys may be reduced by several orders of magnitude when it is reinforced with ceramic particles/whiskers like silicon carbide. The purpose of the present work is to study the isotropic and anisotropic properties with different distribution of material particulates. In many applications,rotating discs are exposed to elevated temperatures where creep deformation becomes important. From this point of view, an attempt has been made to analyze creep in rotating disc made of Al-SiC composites. ····· 1036125001

It is based on selection and ranking problem which aims to select the best population in the sense that the best one is the one associated with the largest (or smallest) parameter. The aim of the estimation following selection is to estimate the parameter of the selected population according to a specific decision rule. In this book, we consider the case of discrete populations like Poisson, power series and for different types of loss functions like k-normalized squared error, Stein and entropy loss functions. Several characteristics of the estimators of the selected population(s) are investigated like unbiasedness,risk-unbiaseness and admissibility and the uniformly minim variance unbiased estimator UMVUE and risk-unbiased estimators are obtained. The admissibility of UMVU and risk-unbiased estimators is also investigated and classes of improved estimators are constructed. Monti Carlo simulation methods are conducted to asses the obtained estimators and compare their performance with the natural estimators. ····· 1036124965
