Signals and Systems
This textbook provides a solid foundation in system modelling, system analysis, and deterministic and random signals and systems, enabling students to develop an instinctive grasp of the fundamentals. The book begins with the basics of analog signals and introduces the concept of DT signals. It then covers the sampling processes in detail and discusses signals and operation on signals for both CT and DT signals. It includes Fourier transform and Laplace transform with adequate theory and numerical problems. With an emphasis on the advanced techniques used for signal processing, especially for speech and image processing, the properties of continuous time and discrete time signals are explained with many numerical problems. Real-life examples are provided to discuss the physical significance of different properties. Besides each concept is presented with MATLAB programs, output plots and simulation examples to help students execute simulations and verify their outputs. The book would interest students of electrical and communication engineering and computer science. This is an exceptional resource for anyone looking to develop their understanding of signals and systems.

Mechanical Engineering Design
We first address the nature of design in general, and then mechanical engineering design in particular. Design is an iterative process with many interactive phases. Many resources exist to support the designer, including many sources of information and an abundance of computational design tools. Design engineers need not only develop competence in their field but they must also cultivate a strong sense of responsibility and professional work ethic. There are roles to be played by codes and standards, ever-present economics, safety, and considerations of product liability. The survival of a mechanical component is often related through stress and strength. Matters of uncertainty are ever-present in engineering design and are typically addressed by the design factor and factor of safety, either in the form of a deterministic (absolute) or statistical sense. The latter, statistical approach, deals with a design's reliability and requires good statistical data.

Serbian Mathematical Olympiad
Until the first edition of this book appearing in 2006, it has been almost impossible to obtain a complete collection of the problems proposed at the IMO in book form. ”The IMO Compendium” is the result of a collaboration between four former IMO participants from Yugoslavia, now Serbia, to rescue these problems from old and scattered manuscripts, and produce the ultimate source of IMO practice problems. This book attempts to gather all the problems and solutions appearing on the IMO through 2009. This second edition contains 143 new problems, picking up where the 1959-2004 edition has left off, accounting for 2043 problems in total.

Engineering Mathematics A
If we want to solve an engineering problem (usually of a physical nature), we first have to formulate the problem as a mathematical expression in terms of variables, functions, and equations. Such an expression is known as a mathematical model of the given problem. The process of setting up a model, solving it mathematically, and interpreting the result in physical or other terms is called mathematical modeling or, briefly, modeling. Modeling needs experience, which we shall gain by discussing various examples and problems. (Your computer may often help you in solving but rarely in setting up models.) Now many physical concepts, such as velocity and acceleration, are derivatives. Hence a model is very often an equation containing derivatives of an unknown function. Such a model is called a differential equation. Of course, we then want to find a solution (a function that satisfies the equation), explore its properties, graph it, find values of it, and interpret it in physical terms so that we can understand the behavior of the physical system in our given problem. However, before we can turn to methods of solution, we must first define some basic concepts needed throughout this chapter.

Secrets in Inequalities
You are now keeping in your hands this new book of elementary inequalities. "Yet another book of inequalities?" We hear you asking, and you may be right. Speaking with the author's words: "Myriads of inequalities and inequality techniques appear nowadays in books and contests. Trying to learn all of them by heart is hopeless and useless. Alternatively, this books objective is to help you understand how inequalities work and how you can set up your own techniques on the spot, not just remember the ones you already learned. To get such a pragmatic mastery of inequalities, you surely need a comprehensive knowledge of basic inequalities at first. The goal of the first part of the book (chapters 1-8) is to lay down the foundations you will need in the second part (chapter 9), where solving problems will give you some practice. It is important to try and solve the problems by yourself as hard as you can, since only practice will develop your understanding, especially the problems in the second part. On that note, this books objective is not to present beautiful solutions to the problems, but to present such a variety of problems and techniques that will give you the best kind of practice."

Complex Variables
The main purpose of this second edition is essentially the same as the first edition with changes noted below. Accordingly, first we quote from the preface by Murray R. Spiegel in the first edition of this text. “The theory of functions of a complex variable, also called for brevity complex variables or complex analysis, is one of the beautiful as well as useful branches of mathematics. Although originating in an atmosphere of mystery, suspicion and distrust, as evidenced by the terms imaginary and complex present in the literature, it was finally placed on a sound foundation in the 19th century through the efforts of Cauchy, Riemann, Weierstrass, Gauss, and other great mathematicians.” “This book is designed for use as a supplement to all current standards texts or as a textbook for a formal course in complex variable theory and applications. It should also be of considerable value to those taking courses in mathematics, physics, aerodynamics, elasticity, and many other fields of science and engineering.” “Each chapter begins with a clear statement of pertinent definitions, principles and theorems together with illustrative and other descriptive material. This is followed by graded sets of solved and supplementary problems. ... Numerous proofs of theorems and derivations of formulas are included among the solved problems. The large number of supplementary problems with answers serve as complete review of the material of each chapter.”
