Internet Rzeczy (IoT). Problemy cyberbezpieczeństwa

Jerzy Krawiec

Monografię można podzielić na dwie zasadnicze części. Pierwsza cześć obejmuje problematykę dotyczącą wyzwań Przemysłu 4.0, a właściwie jego kluczowego elementu, czyli Internetu Rzeczy (IoT). W tej części scharakteryzowano systemy i opisano modele IoT, przedstawiono wizje architektury IoT, zidentyfikowano problem wiarygodności IoT oraz przedstawiono zasady eksploracji danych i standardy komunikacji między urządzeniami systemu IoT. W drugiej części książki podjęto rozważania dotyczące problematyki zapewnienia cyberbezpieczeństwa systemów IoT. Ta część publikacji obejmuje modele odniesienia cyklu bezpieczeństwa urządzeń IoT oraz implementację systemu zarządzania bezpieczeństwem informacji w przedsiębiorstwie realizującym koncepcję IoT. Publikacja jest poparta licznymi przykładami praktycznymi oraz wynikami badań dotyczących poziomów bezpieczeństwa systemów informatycznych pracujących zarówno w sieci globalnej, jak i lokalnej. Jest także praktycznym przewodnikiem wprowadzającym w świat technologii IoT, ze szczególnym uwzględnieniem cyberbezpieczeństwa, przedstawieniem najnowszych zagrożeń internetowych oraz podaniem sposobów ochrony zasobów informacyjnych w przedsiębiorstwach.

Introduction to JVM Languages. Get familiar with the world of Java, Scala, Clojure, Kotlin, and Groovy

Ramasubramanian Sankar, Vincent van der Leun

Anyone who knows software development knows about the Java Virtual Machine. The Java Virtual Machine is responsible for interpreting Java byte code and translating it into actions. In the beginning, Java was the only programming language used for the JVM. But increasing complexity of the language and the remarkable performance of the JVM created an opening for a new generation of programming languages. If you want to build a strong foundation with the Java Virtual Machine and get started with popular modern programming languages, then this book is for you.The book will begin with a general introduction of the JVM and its features, which are common to the JVM languages, helping you get abreast with its concepts. It will then dive into explaining languages such as Java, Scala, Clojure, Kotlin, and Groovy and will show how to work with each language, their features, use cases, and pros and cons. By writing example projects in those languages and focusing on each language’s strong points, it will help you find the programming language that is most appropriate for your particular needs. By the end of the book, you will have written multiple programs that run on the Java Virtual Machine and know about the differences between the various languages.

Introduction to Numerical Methods with 245 Solved Problems

Roman Z. Morawski, Andrzej Miękina

This textbook is the result of the authors' experience of teaching the undergraduate students of the Faculty of Electronics and Information Technology at Warsaw University of Technology in the period 1985-2025, and in particular - the students following the English-medium programmes of study offered there during last 30 years. It is composed of seven chapters devoted to basic numerical problems, such as accuracy of computation, approximation of functions, numerical differentiation and integration, solving algebraic and differential equations. Each chapter contains a short general introduction followed by a considerable number of solved numerical problems. The textbook may be useful for students attending any engineering-oriented course of numerical methods.

Introduction to Programming. Learn to program in Java with data structures, algorithms, and logic

Nick Samoylov

Have you ever thought about making your computer do what you want it to do? Do you want to learn to program, but just don't know where to start? Instead of guiding you in the right direction, have other learning resources got you confused with over-explanations?Don't worry. Look no further. Introduction to Programming is here to help.Written by an industry expert who understands the challenges faced by those from a non-programming background, this book takes a gentle, hand-holding approach to introducing you to the world of programming. Beginning with an introduction to what programming is, you'll go on to learn about languages, their syntax, and development environments. With plenty of examples for you to code alongside reading, the book's practical approach will help you to grasp everything it has to offer. More importantly, you'll understand several aspects of application development. As a result, you'll have your very own application running by the end of the book. To help you comprehensively understand Java programming, there are exercises at the end of each chapter to keep things interesting and encourage you to add your own personal touch to the code and, ultimately, your application.
