The book extensively explores Brain-Computer Interfaces (BCIs), emphasizing both the theoretical foundations and practical applications within this rapidly advancing field. It provides a thorough coverage of BCI fundamentals and practical implementation using MATLAB. It begins with an introduction, covering the history of BCIs, components, and the pivotal role MATLAB plays in their development. The book explores various aspects such as signal processing, data acquisition, rapid prototyping, Machine Learning, and real-time data processing, all within the MATLAB environment. Additionally, it delves into the community and support available, along with open-source BCI toolboxes and integration with external devices. Moving forward, the book dives into the fundamentals of BCIs, including their definition, applications, principles, and components. It discusses their principles, implementation in MATLAB, and practical considerations for training and evaluating classification models. Finally, the book concludes with real-world case studies and practical examples, demonstrating the application of MATLAB in BCI projects.

Название: Advanced Topics in Electric Circuits
Автор: Zdzislaw Trzaska
Издательство: Springer
Год: 2025
Страниц: 506
Язык: английский
Формат: pdf (true)
Размер: 54.8 MB

This book is addressed to researchers and practitioners in the theory and applications of electric circuits. It can also serve as a textbook for Ph.D. students examining applications of modern mathematics to important issues emerging nowadays more and more often in advanced electrical and electronic systems. The book offers effective tools to facilitate the study of all those circuits and systems increasingly penetrating our world, helping to discover their hidden beauty. The material is presented in twelve chapters divided into sections. Usually, first sections are of an introductory nature, explain studied phenomena and announce numerical results. More advanced investigations are presented in subsequent sections. This is the first extensive description of these topics and the interpretations of analytical results and those obtained from computer simulations with MATLAB environments. Special attention is paid to nonlinear electric circuits and finally the presentation is extended to effective applications of the achievements of modern AI.

Algorithms for VLSI Physical Design Automation, 2nd & 3rd Editions
Название: Algorithms for VLSI Physical Design Automation, 2nd & 3rd Editions
Автор: Naveed A. Sherwani
Издательство: Springer / Kluwer
Год: 1995-2002
Формат: pdf/djvu
Страниц: >1500
Размер: 40,2 Мб
Язык: английский

The book is a core reference for graduate students and CAD professionals. For students, concepts and algorithms are presented in an intuitive manner. For CAD professionals, the material presents a balance of theory and practice. An extensive bibliography is provided which is useful for finding advanced material on a topic. At the end of each chapter, exercises are provided, which range in complexity from simple to research level.
Algorithms for VLSI Physical Design Automation, provides a comprehensive background in the principles and algorithms of VLSI physical design. The goal of this book is to serve as a basis for the development of introductory-level graduate courses in VLSI physical design automation. It provides self-contained material for teaching and learning algorithms of physical design. All algorithms which are considered basic have been included, and are presented in an intuitive manner. Yet, at the same time, enough detail is provided so that readers can actually implement the algorithms given in the text and use them.
The first three chapters provide the background material, while the focus of each chapter of the rest of the book is on each phase of the physical design cycle. In addition, newer topics such as physical design automation of FPGAs and MCMs have been included.
The basic purpose of the edition is to investigate the new challenges presented by interconnect and process innovations. In 1995 when the second edition of this book was prepared, a six-layer process and 15 million transistor microprocessors were in advanced stages of design. In 1998, six metal process and 20 million transistor designs are in production. Two new chapters have been added and new material has been included in almost allother chapters. A new chapter on process innovation and its impacton physical design has been added. Another focus of the edition is to promote use of the Internet as a resource, so wherever possible URLs have been provided for further investigation.

There are only few areas of research and development of a comparable scientific and technological extension as microwave and high frequency processing. “Pr- essing” means not only application of radiation of 300 MHz to 300 GHz f- quency to synthesis, heating or ionisation of matter but also generation, transm- sion and detection of microwave and radio frequency radiation. Microwave and high frequency sources positioned in the orbit are the foun- tion of modern satellite telecommunication systems, gyrotron tubes being pr- ently developed in different countries all over the world will most probably be the major devices to open up a new era of energy supply to mankind be means of - sion plasma. Although initiated by military purposes during the Second World War (RADAR, Radio Detection and Ranging), microwave and high frequency utilisation has spread over almost every important aspect of normal day life since than, from individual mobile phones and kitchen microwave ovens to industrial food processing, production of composites as sustainable building materials, green chemistry, medical applications and finally infrastructure installations like GPS and Galileo, to name only few examples. These different areas of microwave and high frequency radiation application can not be unified within one group of scientists and technologists. There are s- eral distinguished communities active e.g., in the area of telecommunication s- tems, strong microwaves for fusion plasma or plasma based materials processing.
