Книга посвящена устройству межсетевых экранов и практическим аспектам работы с ними. Она включает необходимый объем теоретических сведений, в частности описание семейства протоколов TCP/IP и модели OSI, принципы шифрования и организации виртуальных частных сетей и т.д. Представлены все этапы создания межсетевого экрана – планирование, установка и тестирование, – а также процедуры его настройки. Приведены схемы различных конструкций межсетевых экранов, рассмотрены их основные компоненты. В книге упоминается множество бесплатных и коммерческих программ, применяемых в составе межсетевого экрана, детально описаны их установка и конфигурация. Перечислены основные типы атак, изложены рекомендации по защите от них. Издание адресовано сетевым администраторам и пользователям, работа которых связана с эксплуатацией межсетевых экранов.

Just like building physics, performance based building design was hardly an issue before the energy crises of the 1970s. With the need to upgrade energy efficiency, the interest in overall building performance grew. The term «performance» encompasses all building-related physical properties and qualities that are predictable during the design stage and controllable during and after construction. The term «predictable» demands calculation tools and physical models that allow evaluating a design, whereas «controllable» presumes the existence of measuring methods available on site. The basis for a system of performance arrays are the functional demands, the needs for accessibility, safety, well-being, durability, energy efficiency and sustainability and the requirements imposed by the usage of a building. As the first of two volumes, this book applies the performance rationale, advanced in applied building physics, to the design and construction of buildings. After an overview of materials for thermal insulation, water proofing, air tightening and vapour tightening and a discussion on joints, building construction is analysed, starting with the excavations. Then foundations, below and on grade constructions, typical load bearing systems and floors pass the review to end with massive outer walls insulated at the inside and the outside and cavity walls. Most chapters build on a same scheme: overview, overall performance evaluation, design and construction. The book is absolutely recommended to undergraduates and graduates in architectural and building engineering, though also building engineers, who want to refresh their knowledge, may benefit. The level of discussion assumes the reader has a sound knowledge of building physics, along with a background in structural engineering, building materials and building construction. Where and when needed, input and literature from over the world was used, reason why each chapter ends listing references and literature.

In continuation of Vol. 1 this second volume discusses light-weight construction with wooden and metal elements, roofing systems, facades, and ends with finishes and the overall risk analysis.

A breathtaking new collection of translations of poems by Rumi, one of the world’s most loved mystical teachers. Beautifully illustrated with Persian calligraphy, this is an ideal ebook for every MBS reader.Jalal-uddin Rumi was born in what is now Afghanistan in 1207. His poetry has inspired generations of spiritual seekers, both from his own Sufi school and well beyond. His poems speak to the seeker and the lover in all of us.In recent years, interest in Rumi has skyrocketed, with perrfomances, CDs by Deepak Chopra, and filmed versions of his life all in the work. In these beautiful, simple new translations – 100 in all – his timeless appeal is obvious.
