Страниц: 98
Язык: английский
Формат: pdf, epub
Размер: 10.1 MB
It is not easy to explain the meaning of a board like Raspberry Pi for nerds, geeks, coders and anyone involved in technology. On one side, Raspberry Pi is a mini computer and the size substantially changes all possibilities. A mini computer could be placed in a car dashboard or integrated into a kitchen appliance. A mini computer has also minimum power requirements. You can use it with batteries. On the other side, Raspberry Pi has input and output pins capable of being used to connect devices. From programming point of view, this book uses Python due to the simplicity and power. You can mount all projects just by typing the code or you can learn some Python to modify and extend the capabilities. Some projects of this book have electronic components or external parts like push buttons, Leds, relays and all the information about them is also provided. | |

 Название: Pulse Width Modulation In Power Electronics
Автор: Isaak Mayergoyz, Siddharth Tyagi
Издательство: World Scientific Publishing
Год: 2021
Страниц: 419
Язык: английский
Формат: pdf (true), epub

This book provides a theoretical discussion of pulse width modulation (PWM) in power electronic inverters. Pulse width modulation is widely used for the frequency control of speed of ac motors, the design of uninterruptible power supplies (UPS) as well as the integration of renewable energy sources into existing power grid systems. PWM technique is based on approximation of sinusoidal waveforms by sequences (trains) of rectangular pulses whose widths are properly modulated. This width-modulation results in the suppression of low order harmonics at the expense of amplification of high order harmonics which are suppressed by energy-storage elements in load circuits. | |

 Название: Algorithms and Architectures for Cryptography and Source Coding in Non-Volatile Flash Memories
Автор: Malek Safieh
Издательство: Springer
Год: 2021
Формат: ePUB, PDF
Страниц: 155
Размер: 11 Mb
Язык: English
In this work, algorithms and architectures for cryptography and source coding are developed, which are suitable for many resource-constrained embedded systems such as non-volatile flash memories. A new concept for elliptic curve cryptography is presented, which uses an arithmetic over Gaussian integers. Gaussian integers are a subset of the complex numbers with integers as real and imaginary parts. Ordinary modular arithmetic over Gaussian integers is computational expensive. To reduce the complexity, a new arithmetic based on the Montgomery reduction is presented. For the elliptic curve point multiplication, this arithmetic over Gaussian integers improves the computational efficiency, the resistance against side channel attacks, and reduces the memory requirements. Furthermore, an efficient variant of the Lempel-Ziv-Welch (LZW) algorithm for universal lossless data compression is investigated. Instead of one LZW dictionary, this algorithm applies several dictionaries to speed up the encoding process. Two dictionary partitioning techniques are introduced that improve the compression rate and reduce the memory size of this parallel dictionary LZW algorithm. | |

Antenna design and wireless communication has recently witnessed their fastest growth period ever in history, and these trends are likely to continue for the foreseeable future. Due to recent advances in industrial applications as well as antenna, wireless communication, and 5G technology, we are witnessing a variety of developing and expanding new technologies. Compact and low-cost antennas are increasing the demand for ultra-wide bandwidth in next-generation (5G) wireless communication systems and the Internet of Things (IoT). Enabling the next generation of high-frequency communication, various methods have been introduced to achieve reliable high data rate communication links and enhance the directivity of planar antennas. 5G technology can be used in many applications, such as in smart city applications and in smartphones. This technology can satisfy the fast rise in user and traffic capacity in mobile broadband communications. | |

 Название: Handbook of Radar Signal Analysis
Автор: Bassem R. Mahafza, Scott C. Winton

This new handbook on radar signal analysis adopts a deliberate and systematic approach. It uses a clear and consistent level of delivery while maintaining strong and easy-to-follow mathematical details. The emphasis of this book is on radar signal types and their relevant signal processing and not on radar systems hardware or components. This handbook serves as a valuable reference to a wide range of audience. More specifically, college-level students, practicing radar engineers, as well as casual readers of the subject are the intended target audience of the first few chapters of this book. As the book chapters progress, these grow in complexity and specificity. Accordingly, later chapters are intended for practicing engineers, graduate college students, and advanced readers. Finally, the last few chapters contain several special topics on radar systems that are both educational and scientifically entertaining to all readers. | |
