SATELLITE COMMUNICATIONS PAYLOAD AND SYSTEM

A valuable reference on communications satellite systems
This book presents the state of the art in commercial communications satellite systems, thoroughly and in detail not to be found in any other book. These systems provide the television and some of the telephone and Internet services in use every day. The book focuses on the satellite payload, which consists of antennas, receivers, and transmitters. The book discusses the what, the how, and the why of various choices that have been made in currently operating systems.

This textbook describes the main techniques and features of contemporary cryptography, but does so using secondary school mathematics so that the concepts discussed can be understood by non-mathematicians. The topics addressed include block ciphers, stream ciphers, public key encryption, digital signatures, cryptographic protocols, elliptic curve cryptography, theoretical security, blockchain and cryptocurrencies, issues concerning random numbers, and steganography. The key results discussed in each chapter are mathematically proven, and the methods are described in sufficient detail to enable their computational implementation. Exercises are provided.

Why Learn Java: Best Way To Learn Java Programming: Learning Programming Coding
The super-fast evolution of the JDK between versions 8 and 12 has increased the learning curve of modern Java, therefore has increased the time needed for placing developers in the Plateau of Productivity. Its new features and concepts can be adapted to solve a variety of modern-day problems. This book enables you to adopt an objective approach to common problems by explaining the correct practices and decisions with respect to complexity, performance, readability, and more.

Whether it's recommending movies or helping scientists find breakthrough cures, machine learning is a powerful new tool with untold potential.

In the Understanding the basics of machine learning course E-book, we'll explore what these technologies are and how they can be applied in real life to help businesses grow.

There is a rapid growth of automation in server rooms and data centers. The days of having many administrators running around busily configuring and maintaining servers are gone and have been replaced with droves of Salt-Minions; agents beavering away on the target nodes ensuring the configuration is as specified. This book covers Salt Open (also known as SaltStack Open) from the ground up and shows you how to work with two Linux distributions.

This book supports the study of computer networking through the medium of Perl programming. Following an introduction to Perl (in Chapter 1, Meet Perl), the focus is on debugging. Programmers know how to debug programs. When it comes to the network, they need to know how to debug communications. In Chapter 2, Snooping, some simple Perl programs are built to capture and analyse the traffic network applications generate. In the absence of any custom network applications, these simple programs are used to analyse the traffic generated by some standard network technologies.

As Python continues to grow in popularity, projects are becoming larger and more complex. Many Python developers are now taking an interest in high-level software design patterns such as hexagonal/clean architecture, event-driven architecture, and the strategic patterns prescribed by domain-driven design (DDD). But translating those patterns into Python isn’t always straightforward.
