Decision support systems are developed for integrated pest and disease management and nutrition management using open-source technologies as Java, Android and low-cost hardware devices like Arduino micro controller. This text discusses the techniques to convert agricultural knowledge in the context of ontology and assist grape growers by providing this knowledge through decision support system. The key features of the book are as follows: It presents the design and development of an ontology-based decision support system for integrated crop management. It discusses the techniques to convert agricultural knowledge in text to ontology. It focuses on an extensive study of various e-Negotiation protocols for automated negotiations. It provides an architecture for predicting the opponent’s behavior and various factors which affect the process of negotiation. The text is primarily written for graduate students, professionals and academic researchers working in the fields of computer science and engineering, agricultural science and information technology. Dr Gerrard E.J. Poinern holds a Ph.D. in Physics from Murdoch University, Western Australia and a Double Major in Physics and Chemistry. Currently he is is an Associate Professor in Physics and Nanotechnology in the School of Engineering and Information Technology at Murdoch University. He is the director of Murdoch Applied Innovation and Nanotechnology Research Group, Murdoch University. In 2003, he discovered and pioneered the use of an inorganic nanomembrane for potential skin tissue engineering applications. He is the recipient of a Gates Foundation Global Health Grand Challenge Exploration Award for his work in the development of biosynthetic materials and their subsequent application in the manufacture of biomedical devices. He is also the author of the 2014 experimental textbook "A Laboratory Course in Nanoscience and Nanotechnology". Associate Professor Suraj K Tripathy is Associate Dean of the School of Chemical Technology at Kalinga Institute of Industrial Technology, Bhubaneswar, India. He currently leads the Chemical & Bioprocess Engineering Lab (CBEL) at KIIT which focuses on achieving sustainability in materials processing and utilization. CBEL explores opportunities in valorization of waste materials (secondary resources) and investigate their applications in catalysis, water treatment, and biomedical systems. CBEL also works closely with industries to develop suitable waste management and resource recycling strategies to optimize the potential of circular economy model. Dr. Derek Fawcett is the Defence Science Centre research fellow at Murdoch University, Australia. His research involves the investigation and development of new advanced materials and their use in innovative engineering systems. He has published over seventy peer-reviewed research papers in international journals.
