This study describes the onset process of auroral substorms in connection with the vertical evolution of auroral particle acceleration, on the basis of auroral kilometric radiation (AKR) dynamics. We show that the auroral acceleration process at substorm onset basically consists of two stages: (1) appearance/intensification of a low-altitude acceleration region at 4000–5000 km accompanied by in...

While the area of process automation in semiconductor manufacturing has many issues in common with process automation and enactment in business processes, the nature of the semiconductor manufacturing process introduces a number of challenging new issues. Among these issues is the need to not only automate the process but also to continuously control and optimize it. Furthermore the semantics o...

antivenoms have been used successfully for more than a century and up to now constitute the only effective treatment for snakebites .the production of antivenin started long time ago when the calmette was prepared the antivenom in 1894.the method currently used to prepare antivenom by most of the manufacturers are originated from the method of pope which was develop in 1938. several new appr...

Traditional concepts for manufacturing process optimization, e.g., Lean Production and Total Quality Management, represent management-driven and experience-based approaches. The increasing use of cyber-physical systems as well as the digitalization of manufacturing operations management by manufacturing execution systems (MES) lead to enormous amounts of structured and unstructured manufacturin...

Resin Transfer Molding (RTM), as a method for the manufacture of advanced ber reinforced composite materials, is attractive because it ooers the possibility of lower manufacturing costs and more complex shapes than traditional methods. A major issue in this new manufacturing process is the elimination of void spaces in the resin ll operation, so that products with high quality are manufactured....

Strong competition in the manufacturing industry makes efficient and effective manufacturing processes a critical success factor. However, existing warehousing and analytics approaches in manufacturing are coined by substantial shortcomings, significantly preventing comprehensive process improvement. Especially, they miss a holistic data base integrating operational and process data, e. g., fro...

In many manufacturing processes, some key process parameters have very strong relationship with the normal or various faulty products of finished products. The abnormal changes of these process parameters could result in various categories of faulty products. In this paper, a data mining model is developed for on-line intelligent monitoring and diagnosis of the manufacturing processes. In the p...

the relationship between the manufacturer and supplier has changed from one of competition into that of greater cooperation during recent years. the selection and evaluation of suppliers are primary and important issues when an enterprise implements supplier relationship management (srm) and total quality management (tqm). much research indicates that most enterprises tend to evaluate their sup...

To manufacture a product, nowadays there are many methods available in the market to manufacture them and to earn more profits and best production which is the prime focus of any manufacturing industry, it is necessary to select only that type of manufacturing process which leads to more profits, less scraps, and reworks, faster production rate, good quality of production, employee satisfaction...
