Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...

General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...

BACKGROUND Recent evidence suggests that a low carbohydrate (LC) diet may be equally or more effective for short-term weight loss than a traditional low fat (LF) diet; however, less is known about how they compare for weight maintenance. The purpose of this study was to compare body weight (BW) for participants in a clinical weight management program, consuming a LC or LF weight maintenance die...

Most production scheduling problems, including High-Variety, Low-Volume (HVLV) scheduling problems assume that machines are continuously available. However, in most actual situations, machines become unavailable during certain periods when preventive maintenance (PM) is scheduled. In this paper, a HVLV scheduling problem is proposed while considering machines availability constraints. Each mach...

Although coordination of multiple activities is a fundamental goal of object-oriented concurrent programming languages, there is only limited support for its specification and abstraction at the language level. This leads to a mismatch between conceptional designs, using high-level abstractions, and the implementation, using the low-level coordination constructs. Often coordination is hard-wire...

Data fusion allows the elaboration and the evaluation of a situation synthesized from low level informations provided by different kinds of sensors. The fusion of the collected data will result in fewer and higher level informations more easily assessed by a human operator and that will assist him effectively in his decision process. In this paper we present the suitability and the advantages o...

The Global Accelerator Network is a proposed model for remote operation of a future large accelerator by the partners of an international collaboration. The remote functionality would include not only routine operation and machine studies, but also hardware diagnostic tests and software maintenance and development, so the control system must offer both high and low level remote access to the ac...

The application of low-calorie sweeteners (LCS) in foods and beverages has increased over the past 35 y. At the same time, many characteristics of the American diet have changed, including variations in fat and carbohydrate content and composition, increased nutrient additions, and new dietary patterns due to changing lifestyles and attitudes toward food and the changing cost of food. During th...

Source code investigation is one of the most time consuming activities during software maintenance and evolution, yet currently available tool support suffers from several shortcomings. Browsing is typically limited to low-level elements, investigation is only supported as a one-way activity, and tools provide little help in getting an encompassing picture of the system under examination. In ou...
