Cement industry control system based on multi agent

Cement production is characterized by its great capacity, long-time delay, multi variables, difficult measurement and multi disturbances. According to the distributed intelligent control strategy based on the multi (agent,) the multi agent control system of cement production is built, which includes integrated optimal control and diagnosis control. The distributed and multiple level structure of multi agent system for the cement control is studied. The optimal agent is in the distributed state, which aims at the partial process of the cement production, and forms the optimal layer. The diagnosis agent located on the diagnosis layer is the diagnosis unit which aims at the whole process of the cement production, and the central management unit of the system. The system cooperation is realized by the communication among optimal agents and diagnosis agent. The architecture of the optimal agent and the diagnosis agent are designed. The detailed functions of the optimal agent and the diagnosis agent are analyzed. At last the realization methods of the agents are given, and the application of the multi agent control system is presented. The multi agent system has been successfully applied to the off-line control of one cement plant with capacity of 5 000 t/d. The results show that the average yield of the clinker increases 9.3% and the coal consumption decreases 7.5 kg/t.

Development of New Macadamia Products

The macadamia tree （macadamia integrifolia maiden ＆ betche）, originally from Australia, has smooth and rounded fruits, this walnut produces richly flavoured nuts, which are used ＂in natura＂ accompanying appetizers, in the manufacture of candies, being well accepted by the population. This paper analysed the production process of the agro industrial cooperative producers of macadamia nut （Coopmac）, located in the town of Sao Mateus-ES/Brazil, and responsible for the production and marketing benefits for the states of Espirito Santo and Bahia. This analysis was performed in order to identify new opportunities for developing new products. The following steps were explored： analysis of the current procedure, ideas generation, analysis of potential ideas, development of a product concept and development of a prototype product. In cooperative, macadamia oil was only extracted. It was decided to develop a potential product from this oil. Initially, chemical analyzes were performed with this oil and opted for the production of soaps, liquid and bar. During this step, the methodology of design of experiments was used to develop the prototype. Sensory analysis, based on the LAM type hedonic scale, was used in the tests. The data were analyzed and could be distinguished the best formulation and the main effects for each assessed parameter. In this step, the statistical analysis software was used. From the value of the overall quality of the sample, greater acceptance for liquid soaps was obtained for a formulation with lower oil volume and higher volume of amphoteric. When concerning the sample bar soaps, the best formulation had the lower ratio of oil volume, the higher volume of amphoteric and lower mass of clay. The authors expect to contribute to generation of scientific and technological knowledge in order to effectively meet the practical needs of efforts directed to the production of macadamia nuts in the state of Espirito Santo.

The Strategic Importance of Cereal Virtual Water in Algeria： Report and Perspectives

In order to quantify the virtual water part which is contained in the imported cereals, compared with the hydraulic potentialities which are annually mobilised through the national territory, and on the basis of the agricultural statistics, we have determined the average quantities of the imported cereals per year in order to determine the virtual water volume that these cereals bind. The water needs of the cereals which are produced in Algeria have been calculated by the Cropwat software, in order to define the equivalent quantities of water in their production on the national scale. The obtained results confirm the importance of the annually imported virtual water, through the imported cereals, comparing with the national hydraulic potentialities. Our study shows also that in spite of the strategic importance of the virtual water in the imported cereals, a diminution has to take place, on the average term, by an improvement of the use efficiency of the precipitations （green virtual water） using the best mastery of the technical itinerary in general, and also the efficient use of precipitations in particular.

On Hybrid Computer-Aided Tools to Interface Design Data

Recognizing the drawbacks of stand-alone computer-aided tools in engineering, several hybrid systems are suggested with varying degree of success. In transforming the design concept to a finished product, in particular, smooth interfacing of the design data is crucial to reduce product cost and time to market. Having a product model that contains the complete product description and computer-aided tools that can understand each other are the primary requirements to achieve the interfacing goal. This article discusses the development methodology of hybrid engineering software systems with particular focus on application of soft computing tools such as genetic algorithms and neural networks. Forms of hybridization options are discussed and the applications are elaborated using two case studies. The forefront aims to develop hybrid systems that combine the strong side of each tool, such as, the learning, pattern recognition and classification power of neural networks with the powerful capacity of genetic algorithms in global search and optimization. While most optimization tasks need a certain form of model, there are many processes in the mechanical engineering field that are difficult to model using conventional modeling techniques. The proposed hybrid system solves such difficult-to-model processes and contributes to the effort of smooth interfacing design data to other downstream processes.

Application of automated image analysis to the identification and extraction of recyclable plastic bottles

An experimental machine vision apparatus was used to identify and extract recyclable plastic bottles out of a conveyor belt. Color images were taken with a commercially available Webcam, and the recognition was performed by our homemade software, based on the shape and dimensions of object images. The software was able to manage multiple bottles in a single image and was additionally extended to cases involving touching bottles. The identification was fulfilled by comparing the set of measured features with an existing database and meanwhile integrating various recognition techniques such as minimum distance in the feature space, self-organized maps, and neural networks. The recognition system was tested on a set of 50 different bottles and provided so far an accuracy of about 97% on bottle identification. The extraction of the bottles was performed by means of a pneumatic arm, which was activated according to the plastic type; polyethylene-terephthalate (PET) bottles were left on the conveyor belt, while non-PET bottles were extracted. The software was designed to provide the best compromise between reli-ability and speed for real-time applications in view of the commercialization of the system at existing recycling plants.
