Today, more and more antenna engineers are viewing the Dielectric Resonator Antenna (DRA) as a preferable alternative to conventional low-gain designs because of several attractive features, including high radiation, light weight, small size and low profile. This practical resource presents complete, up-to-date details on DRAs in a single volume. The book provides professionals with clear guidance on the mode of operation and radiation behavior of DRAs, the main methods of excitation, and the major advances in DRA technology. This hands-on reference equips engineers with simple equations and graphs that help them rapidly design DRAs, without the need for complex analytical or numerical calculations. Numerous design examples are included to give practitioners a sense of the versatility that DRAs afford.

Prepare yourself for any type of audit and minimise security findings DESCRIPTION This book is a guide for Network professionals to understand real-world information security scenarios. It offers a systematic approach to prepare for security assessments including process security audits, technical security audits and Penetration tests. This book aims at training pre-emptive security to network professionals in order to improve their understanding of security infrastructure and policies. Ê With our network being exposed to a whole plethora of security threats, all technical and non-technical people are expected to be aware of security processes. Every security assessment (technical/ non-technical) leads to new findings and the cycle continues after every audit. This book explains the auditorÕs process and expectations. KEY FEATURES It follows a lifecycle approach to information security by understanding: Why we need Information security How we can implementÊ How to operate securely and maintain a secure posture How to face audits WHAT WILL YOU LEARN This book is solely focused on aspects of Information security that Network professionals (Network engineer, manager and trainee) need to deal with, for different types of Audits. Information Security Basics, security concepts in detail, threat Securing the Network focuses on network security design aspects and how policies influence network design decisions. Secure Operations is all about incorporating security in Network operations. Managing Audits is the real test. WHO THIS BOOK IS FOR IT Heads, Network managers, Network planning engineers, Network Operation engineer or anybody interested in understanding holistic network security. Table of Contents _1.

Antarctic Comrades chronicles an American scientist's adventure with a Soviet research team in 1960. This book is Gilbert Dewart's description of the work accomplished at the Mirnyy research station and of a four-month summertime trek inland to Vostok, another Soviet station in the coldest part of Antarctica. It illuminates an event during the Eisenhower/Kennedy/Khrushchev era, an early attempt at glasnost, and the evolution of the international scientific community.
