Expert Systems in Mineral and Metal Processing


Book Description

Within the metal and mining industries, the use of expert systems for monitoring and control is on the increase. The content of each paper had to include both expert systems, neural networks or fuzzy control. The papers were evenly contributed from industry, universities and research institutes, thus this book provides a valuable insight into the theoretical as well as the practical applications currently in use within the industry.










Industrial Applications of Soft Computing


Book Description

Applications of Soft Computing have recently increased and methodological development has been strong. The book is a collection of new interesting industrial applications introduced by several research groups and industrial partners. It describes the principles and results of industrial applications of Soft Computing methods and introduces new possibilities to gain technical and economic benefits by using this methodology. The book shows how fuzzy logic and neural networks have been used in the Finnish paper and metallurgical industries putting emphasis on processes, applications and technical and economic results.




Automation in Mining, Mineral, and Metal Processing 1995 (MMM'95)


Book Description

When the South African Council for Automation and Computation (SACAC) first submitted a bid to host the 8th IFAC Symposium on Automation in Mining, Mineral and Metal Processing in Beijing, many obstacles were evident. Most of these were embodied in negative international attitudes to the government of the Republic of South Africa and the apartheid society it supported. However, it is to the credit of the IFAC working group on automation in mining, mineral and metal processing that their application at that time was considered favourably, although not formally accepted. It took a visit to the 10th IFAC World Congress in Sydney and a visible shift in the political scenario to persuade the relevant IFAC committees that South Africa would be suitable for the symposium. A national organising committee was formed under the leadership of SACAC and the South African Institute of Measurement and Control (SAIMC), the South African Institute of Electrical Engineers (SAIEE) and the South African Institute for Mining and Metallurgy (SAIMM). The combined team set about organising the first major IFAC international symposium in South Africa since 1976. The theme for the Symposium was based on the need to promote technology transfer and papers which addressed this issue were favoured. With over 50% of the authors from other countries, a significant opportunity for technology transfer into South Africa was created, which is in keeping with the overall theme.




Expert Systems


Book Description

Expert systems represent a branch of artificial intelligence aiming to take the experience of human specialists and transfer it to a computer system. The knowledge is stored in the computer, which by an execution system (inference engine) is reasoning and derives specific conclusions for the problem. The purpose of expert systems is to help and support user’s reasoning but not by replacing human judgement. In fact, expert systems offer to the inexperienced user a solution when human experts are not available. This book has 18 chapters and explains that the expert systems are products of artificial intelligence, branch of computer science that seeks to develop intelligent programs. What is remarkable for expert systems is the applicability area and solving of different issues in many fields of architecture, archeology, commerce, trade, education, medicine to engineering systems, production of goods and control/diagnosis problems in many industrial branches.




Smithells Metals Reference Book


Book Description

Smithells is the only single volume work which provides data on all key apsects of metallic materials. Smithells has been in continuous publication for over 50 years. This 8th Edition represents a major revision. Four new chapters have been added for this edition. these focus on; * Non conventional and emerging materials - metallic foams, amorphous metals (including bulk metallic glasses), structural intermetallic compounds and micr/nano-scale materials. * Techniques for the modelling and simulation of metallic materials. * Supporting technologies for the processing of metals and alloys. * An Extensive bibliography of selected sources of further metallurgical information, including books, journals, conference series, professional societies, metallurgical databases and specialist search tools. * One of the best known and most trusted sources of reference since its first publication more than 50 years ago * The only single volume containing all the data needed by researchers and professional metallurgists * Fully updated to the latest revisions of international standards




Processing of Complex Ores


Book Description

A broad spectrum of the subject from basic research to plant applications has been covered. Flotation and hydrometallurgy have attracted a good deal of interest in view of their growing importance in the processing of complex ores. Physical methods including magnetic and gravity separation techniques have received attention in the processing of tantalum, niobium and tungsten. In addition, a set of papers is devoted to expert systems and their applications in mineral processing plants.




Robust Industrial Control Systems


Book Description

Robust Industrial Control Systems: Optimal Design Approach for Polynomial Systems presents a comprehensive introduction to the use of frequency domain and polynomial system design techniques for a range of industrial control and signal processing applications. The solution of stochastic and robust optimal control problems is considered, building up from single-input problems and gradually developing the results for multivariable design of the later chapters. In addition to cataloguing many of the results in polynomial systems needed to calculate industrial controllers and filters, basic design procedures are also introduced which enable cost functions and system descriptions to be specified in order to satisfy industrial requirements. Providing a range of solutions to control and signal processing problems, this book: * Presents a comprehensive introduction to the polynomial systems approach for the solution of H_2 and H_infinity optimal control problems. * Develops robust control design procedures using frequency domain methods. * Demonstrates design examples for gas turbines, marine systems, metal processing, flight control, wind turbines, process control and manufacturing systems. * Includes the analysis of multi-degrees of freedom controllers and the computation of restricted structure controllers that are simple to implement. * Considers time-varying control and signal processing problems. * Addresses the control of non-linear processes using both multiple model concepts and new optimal control solutions. Robust Industrial Control Systems: Optimal Design Approach for Polynomial Systems is essential reading for professional engineers requiring an introduction to optimal control theory and insights into its use in the design of real industrial processes. Students and researchers in the field will also find it an excellent reference tool.
