Book Description
This publication emphasises that an interdisciplinary and multi-disciplinary cooperation of scientists throughout the world is important in solving the complex problems facing the greenhouse industry. The book itself is an outstanding example of such cooperation.The aim of the book is to describe and analyse crop production in greenhouses in relation to climate control, to redefine the problem of (optimal) control from a theoretical point of view, and to provide a suitable framework for the design of new, scientifically based control systems. Though the principles are generally applicable, they are discussed against the background of the Dutch greenhouse industry. To provide the reader with some background information, the historical developments and the economic position of the Dutch horticultural industry are briefly reviewed in the introductory chapter. ...this book will certainly become a reference as such an extensive review on the greenhouse-crop system and its control is lacking for research and teaching...

Book Description
Crop production in greenhouses is a growing industry, especially in mild climates, and is very important for the population as a source of income and clean, fresh food. Greenhouses create optimal climate conditions for crop growth and protect crops from outside pests. At the same time greenhouse production increases water use efficiency and makes integrated production and protection (IPP) possible. This book provides technical instructions for practice (what to do and what not to do) and gives answers to the question: How to produce more clean crops and better quality with less water, less land and less pesticide. Suitable greenhouse constructions and their design, adapted to local climates in subtropical, tropical and arid regions and infrastructure conditions are presented. The necessary climate control measures - light transmittance, ventilation, cooling, heating, and CO2 enrichment - and physical measures for pest control, as well as methods for using solar energy to desalinate salty water are described. The results of theoretical research are transferred into methods for practical use, so that readers are equipped to solve their problems in practice as well as to get stimulation for further research and development.

Book Description
This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

Book Description
A discussion of challenges related to the modeling and control of greenhouse crop growth, this book presents state-of-the-art answers to those challenges. The authors model the subsystems involved in successful greenhouse control using different techniques and show how the models obtained can be exploited for simulation or control design; they suggest ideas for the development of physical and/or black-box models for this purpose. Strategies for the control of climate- and irrigation-related variables are brought forward. The uses of PID control and feedforward compensators, both widely used in commercial tools, are summarized. The benefits of advanced control techniques—event-based, robust, and predictive control, for example—are used to improve on the performance of those basic methods. A hierarchical control architecture is developed governed by a high-level multiobjective optimization approach rather than traditional constrained optimization and artificial intelligence techniques. Reference trajectories are found for diurnal and nocturnal temperatures (climate-related setpoints) and electrical conductivity (fertirrigation-related setpoints). The objectives are to maximize profit, fruit quality, and water-use efficiency, these being encouraged by current international rules. Illustrative practical results selected from those obtained in an industrial greenhouse during the last eight years are shown and described. The text of the book is complemented by the use of illustrations, tables and real examples which are helpful in understanding the material. Modeling and Control of Greenhouse Crop Growth will be of interest to industrial engineers, academic researchers and graduates from agricultural, chemical, and process-control backgrounds.

Book Description
Heat and mass transfer is the core science for many industrial processes as well as technical and scientific devices. Automotive, aerospace, power generation (both by conventional and renewable energies), industrial equipment and rotating machinery, materials and chemical processing, and many other industries are requiring heat and mass transfer processes. Since the early studies in the seventeenth and eighteenth centuries, there has been tremendous technical progress and scientific advances in the knowledge of heat and mass transfer, where modeling and simulation developments are increasingly contributing to the current state of the art. Heat and Mass Transfer - Advances in Science and Technology Applications aims at providing researchers and practitioners with a valuable compendium of significant advances in the field.
