Symbolic analyzers have the potential to offer knowledge to sophomores as well as practitioners of analog circuit design. Actually, they are an essential complement to numerical simulators, since they provide insight into circuit behavior which numerical analyzers do not provide. Symbolic analysis of electronic circuits addresses the generation of symbolic expressions for the parameters that describe the performance of linear and nonlinear circuits in three domains: DC, AC and time; some or all the circuit parameters can be kept as symbols. Due to the fact that these expressions remain valid during the change of component values (as long as models remain valid), designers can have both, an insight into the behavior of the network and use the expressions to optimize the circuit’s performances. This e-book presents, details and exemplifies famous symbolic analysis techniques. Industrial R&D topics, recent developments and future trends in the field of symbolic analysis are also highlighted. This makes the e-book a good resource for circuit analysis. Thus, it is intended for students and researchers as well as for industry designers.

Titanium and its alloys have been widely used as biomedical implant materials due to their low density, good mechanical properties, superior corrosion resistance and biocompatibility when compared with other metallic biomaterials such as Co–Cr alloys and stainless steels. Recently, β-type titanium alloys have been increasingly considered as excellent implant materials because of the remarkable combination of high strength-to-weight ratio, good fatigue resistance, relatively low Young's modulus, good biocompatibility and high corrosion resistance relative to conventional titanium biomaterials. This book covers recent information about biomedical titanium alloy development and 3D printing. Chapters describe the processing, microstructure, mechanical properties and corrosion properties in detail. Information about the surface modification of titanium alloys for biomedical applications, and manufacturing of titanium alloys by new technologies (such as selective laser melting and electron beam melting), is also presented. Readers will learn about the various types of biomedical titanium alloys, their advantages and disadvantages, their fabrication methods and medical applications. This book is a useful handbook for biomedical engineers, metallurgists and biotechnicians seeking information about titanium-based alloys for biomaterials research and development.

Sustainability is a major concern when considering the construction of a new building project as there is a definite effect of any construction on its surrounding environment. One tool to measure the environmental impact of projects is the Ecological Footprint (EF). Ecological Footprint Assessment of Building Construction: Spanish Case Study presents the methodology required for the creation of an effective EF assessment of building construction projects with a case study of a Spanish project. The book starts with a detailed overview of the EF indicator for buildings including definitions, methodologies and scale applications. This is followed by chapters on dwelling construction methodology and calculation models for direct (energy and water), indirect (manpower and construction materials) resource consumption and waste in the constructed area. The book concludes with a case study that demonstrates the application of all types of EF indicators mentioned in the previous chapters. The methodology and all steps for each calculation are explained in detail, making the book an applicable reference for working professionals as well as an easy-to-understand guide for graduates undertaking sustainability modules in ecology and civil engineering courses

The E-book is intended for helping engineers and students to analyze EMI problems in electrical and electronic systems.

Electromagmetics for Engineering Students is a textbook in two parts, Part I and II, that cover all topics of electromagnetics needed for undergraduate students from vector analysis to antenna principles. In both parts of the book, the topics are presented in sufficient details such that the students will follow the analytical development easily. Each chapter is supported by many illustrative examples, solved problems, and the end of chapter problems to explain the principles of the topics and enhance the knowledge of the student. There are a total of 681 problems in the both parts of the book as follows: 162 illustrative examples, 88 solved problems, and 431 end of chapter problems. This part is a continuation of Part I and focuses on the application of Maxwell's equations and the concepts that are covered in Part I to analyze the characteristics of wave propagation in half-space and bounded media including metamaterials. Moreover, a chapter has been devoted to the topic of antennas to provide readers with the fundamental concepts related to antenna engineering.

This book is unique when compared with books on non-linear circuits and systems. The book introduces novel concepts of physics, computer and electrical engineering. The synthesis of Multi-scroll chaotic oscillators is performed through three hierarchical levels of abstractions. A good repertoire of multi-scroll chaos generators is presented by dealing with 1D, 2D ad 3D oscillators which require one, two or three piece-wise linear functions, respectively. Each function is designed using operational amplifiers. Since the approach uses behavioral models, other electronic devices including novel integrated circuits can be used to design the chaos generators. This is an important part of the book since it opens new lines of research while holding a tutorial characteristic for educational purposes. The book is recommended for electronic design students and professionals.
