 Название: Digital Electronic : Analog And Digital

Digital electronics is the sub-branch of electronics that deals with digital signals for processing and controlling various systems and sub-systems. In various applications like sensors and actuators, usage of digital electronics is increasing extensively. Mainly the analog realm of electronics - circuits that accept and respond to voltages that vary continuously over a given range. Such analog circuits included rectifiers, filters, amplifiers, simple RC timers, oscillators, simple transistor switches, etc. Although each of these analog circuits is fundamentally important in its own right, these circuits lack an important feature - they cannot store and process bits of information needed to make complex logical decisions. To incorporate logical decision-making processes into a circuit, you need to use digital electronics. | |

 Название: Self Aware Security for Real Time Task Schedules in Reconfigurable Hardware Platforms
Автор: Krishnendu Guha, Sangeet Saha
Издательство: Springer
Год: 2021
Страниц: 194
Язык: английский
Формат: pdf (true), epub
Размер: 39.6 MB
This book focuses on how real-time task schedules for reconfigurable hardware-based embedded platforms may be affected due to the vulnerability of hardware and proposes self-aware security strategies to counteract the various threats. The emergence of Industry 4.0 has witnessed the deployment of reconfigurable hardware or field programmable gate arrays (FPGAs) in diverse embedded applications. These are associated with the execution of several real-time tasks arranged in schedules. However, they are associated with several issues. Development of fully and partially reconfigurable task schedules are discussed that eradicates the existing problems. However, such real-time task schedules may be jeopardized due to hardware threats. | |

 Название: An Integrated Approach to Home Security and Safety Systems
Автор: Sonali Goyal, Neera Batra, N.K. Batra
Издательство: CRC Press
Год: 2022
Формат: True PDF
Страниц: 191
Размер: 20,8 Mb
Язык: English
This book provides an integrated solution for security and safety in the home, covering both assistance in health monitoring and safety from strangers/intruders who want to enter the home with harmful intentions. It defines a system whereby recognition of a person/stranger at the door is done using three modules: Face Recognition, Voice Recognition and Similarity Index. These three modules are taken together to provide a percentage likelihood that the individual is in the "known" or "unknown" category. The system can also continuously monitor the health parameters of a vulnerable person living alone at home and aid them in calling for help in an emergency. | |

 Название: Metamaterials for Antenna Applications
Автор: Amit K. Singh, Mahesh P. Abegaonkar
Издательство: CRC Press
Год: 2022
Страниц: 215
Язык: английский
Формат: pdf (true)
Размер: 41.0 MB
The book presents an engineering approach for the development of metamaterials and metasurfaces with emphasis on application in antennas. It offers an in-depth study, performance analysis and extensive characterization on different types of metamaterials and metasurfaces. Practical examples included in the book will help readers to enhance performance of antennas and also develop metamaterial-based absorbers for a variety of applications. Metamaterials are artificially engineered homogeneous materials that exhibit unusual electromagnetic (EM) properties not existing in nature. These artificially engineered materials have the capability to modify incoming EM waves in many ways that are beyond naturally existing bulk materials. Miniaturized antennas are the major requirement for microwave monolithic integrated circuits to provide proper communication solution. The desire to incorporate multiple frequency bands of operation into personal communication devices has led to much research on reducing the size of antennas while maintaining adequate performance. In addition, antennas and RF front ends, which form the integral part of a wireless system, have not been exempted from the demand for miniaturization. | |

This book describes how we can design and make efficient processors for high-performance computing, AI, and data science. Although there are many textbooks on the design of processors we do not have a widely accepted definition of the efficiency of a general-purpose computer architecture. Without a definition of the efficiency, it is difficult to make scientific approach to the processor design. In this book, a clear definition of efficiency is given and thus a scientific approach for processor design is made possible. | |
