The measurement of dependability attributes on real systems is a very time-consuming and costly affair, making analytical or simulation modeling the only viable solutions. Dependability of Networked Computer-based Systems explores reliability, availability and safety modeling of networked computer-based systems used in life-critical applications such as avionics, nuclear power plants, automobiles and chemical process industries.Dependability of Networked Computer-based Systems gives an overview of basic dependability modeling concepts and addresses new challenges in dependability modeling of networked computer-based systems, as well as new trends, their capabilities and limitations. It covers a variety of dependability modeling methods:stochastic processes,Markov and semi-Markov models,response-time distribution,stochastic Petri-net-based modeling formalisms, andMonte Carlo simulation models.Dependability of Networked Computer-based Systems provides students and researchers with a detailed overview of dependability models and analysis techniques. Practicing engineers will also find this text a useful guide to decision-making based on system dependability at the design, operation and maintenance stages.

This book delves into the fundamentals of steganography, the ancient art of hiding messages in plain sight. From the historical roots to modern applications, readers are taken on a journey through the techniques that transform seemingly ordinary content into carriers of covert communication. The book not only demystifies the basics of steganography but also sheds light on its contemporary applications in digital security, forensics, and confidential messaging. Beginning with the ancient origins of hidden writing, the book builds a clear picture of how steganography has evolved alongside cryptography and cybersecurity. It then moves into the digital realm, explaining with clarity how messages are embedded within images, audio and video files, and how these methods are analyzed, tested, and, ultimately, uncovered. Balancing theory with application, the text introduces key measures of quality, such as PSNR and MSE, and unpacks practical techniques used for both embedding and detecting hidden data. The discussion of steganalysis tools is especially valuable, giving readers a grounded understanding of the strengths and limitations of current approaches. Applications are drawn from real-world domains – from digital forensics and cyber defense to secure communications – demonstrating why steganography matters not only as a technical discipline but as a practical skill. The authors also look ahead, surveying the challenges posed by increasingly complex media formats and the potential directions of future research.

Ce livre se concentre sur le r le de la fertilisation la chaux et au bore dans l'am lioration de la croissance, de la productivit et de la qualit du soja (Glycine max (L.) Merrill). Il explique comment l'acidit du sol et la carence en bore constituent des contraintes majeures pour la culture du soja et souligne l'importance d'une gestion quilibr e des nutriments pour surmonter ces limitations. Le livre traite des effets individuels de la chaux dans l'am lioration des sols acides et l'augmentation de la disponibilit des nutriments, ainsi que des fonctions critiques du bore dans la croissance des plantes, la floraison et le d veloppement des graines. L'accent est galement mis sur l'interaction synergique entre la chaux et le bore et leur impact combin sur la nodulation, les caract ristiques de rendement et la qualit des semences. Con u pour les tudiants, les chercheurs et les professionnels de la vulgarisation, ce livre fournit des informations pratiques et scientifiques pour parvenir une production de soja durable et efficace dans diverses conditions agro- cologiques.

Dieses Buch befasst sich mit der Rolle von Kalk- und Bord ngung bei der Verbesserung von Wachstum, Produktivit t und Qualit t von Sojabohnen (Glycine max (L.) Merrill). Es wird erl utert, wie Bodens ure und Bormangel den Sojabohnenanbau stark einschr nken und wie wichtig ein ausgewogenes N hrstoffmanagement ist, um diese Einschr nkungen zu berwinden. Das Buch er rtert die einzelnen Wirkungen von Kalk zur Verbesserung saurer B den und zur Erh hung der N hrstoffverf gbarkeit sowie die kritischen Funktionen von Bor f r das Pflanzenwachstum, die Bl te und die Samenentwicklung. Ein weiterer Schwerpunkt liegt auf der synergetischen Wechselwirkung zwischen Kalk und Bor und ihren kombinierten Auswirkungen auf Kn llchenbildung, Ertragsmerkmale und Saatgutqualit t. Das Buch richtet sich an Studenten, Forscher und Berater und liefert praktische und wissenschaftliche Erkenntnisse f r eine nachhaltige und effiziente Sojaproduktion unter verschiedenen agro- kologischen Bedingungen.

This book focuses on the role of lime and boron fertilization in improving the growth, productivity, and quality of soybean (Glycine max (L.) Merrill). It explains how soil acidity and boron deficiency act as major constraints to soybean cultivation and highlights the importance of balanced nutrient management in overcoming these limitations. The book discusses the individual effects of lime in ameliorating acidic soils and enhancing nutrient availability, as well as the critical functions of boron in plant growth, flowering, and seed development. Emphasis is also given to the synergistic interaction between lime and boron and their combined impact on nodulation, yield attributes, and seed quality. Designed for students, researchers, and extension professionals, the book provides practical and scientific insights for achieving sustainable and efficient soybean production under diverse agro-ecological conditions.
