Ventilation Systems Book

EBook Description: Properly designed ventilation systems for cooling, heating and cleaning the outdoor air supplied to buildings are essential for maintaining good indoor air quality as well as for reducing a building�s energy consumption. Modern developments in ventilation science need to be well understood and effectively applied to ensure that buildings are ventilated as efficiently as possible. Ventilation Systems provides up-to-date knowledge based on the experience of internationally recognised experts to deal with current and future ventilation requirements in buildings. Presenting the most recent developments in ventilation research and its applications, this book offers a comprehensive reference to the subject, covering the fundamentals as well as more advanced topics. It is a unique publication as it covers the subject rigorously in a way needed by researchers but has a practical flavour that will be of value to a wide range of building professionals.

Here is a chess book that homes in on the properties of the chessboard itself. College professor Watkins informs readers that the chessboard and chess pieces can be analyzed in terms of graph theory, which has real-world relevance--to the structure of communications networks, for example. And Watkins indeed sets up his tour of chess-qua-graph theory as a collection of problems to be solved, and theorems to be proven, all on the difficulty level one encounters in Scientific American's popular feature "Mathematical Games." When he was a teenager, comments Watkins, that column alerted him to the chessboard's mathematical intricacies, which encompass the number of squares a piece can move to or control, with variations extending to boards of different sizes and shapes. Torus-shaped boards, three-dimensional boards, a shape called the Klein bottle--the simple checkerboard pattern proves to be creatively malleable when Watkins puts his mind to his hobbylike subject. Watkins' invitational tone ensures attention from the finite but enthusiastic audience for mathematical recreation.
