Abstract:

This paper reports the findings of the first stage of a study on how the efficiency of a centrifugal pump depends on the eccentricity of the impeller (rotor). The geometry of the pump is based on the ERCOFTAC centrifugal pump that has been used to validate computational fluid dynamics software with laboratory measurements. The pump is modelled using the CFD-code Comsol multi physics (tm) in order to get the pressure and velocity field. From the pressure and velocity field the efficiency and output power for the pump is calculated. The energy efficiency of the same pump with different static ec

Abstract:

Ultrasonic cleaning baths are routinely used for cleaning dental and surgical instruments. The importance of efficient cleaning prior to sterilisation is great. Micro-organisms can survive the sterilisation process as debris can act as an insulator. The information available on ultrasonic field distributions in cleaning baths is limited. A thermal technique, employing a thermistor probe coated with an absorbing material measures the temperature rise when the field is switched on compared to no sound temperature. Contour plots of the field of the cleaning bath resulted from point-to-temperature

Recognizing that libraries and usage may grow, service providers are intensely interested in large-scale content delivery networks that provide content propagation, storage, streaming, and transport.

Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less power when operating if the power supply were upgraded from 40% efficiency to 80% efficiency. Savings can occur not only from using SMPS's instead of linear power supplies, but also from specifying highly efficient switching power supplies. In many cases,

Abstract:

With the increase in population and industrial growth, the need for power has increased manifold. A major share of India’s power generation is coal-based generation. Thermal power generation through coal combustion produces minute particles of ash that causes serious environmental problems. Most of the thermal power stations in India use bituminous coal and produce large quantities of fly ash. Fly ash is produced primarily by thermal power plants and, to a lesser extent, by cement and steel plants and railways. This poses problems in the form of land use, health hazards, and environmental dang

If it found out exception, this lot will stop to process.Thus, it can avoid miss-operation and all wafer in this lot usable. In the measure tools, it can collect wafer measure data and response them to Manuafacture Execution System (MES) to analysis data. Tthis method only can control lot to lot monitor.

碩士<br>元智大學<br>管理碩士在職專班<br>104<br>This study employs the method of case study to explore how to enhance the efficiency of maintenance. In our study the maintenance management is viewed as a base to ensure that the equipment would operate normally, the maintenance rate is reduced, and the status of equipment maintenance is efficiently controlled due to preventive maintenance. The case in our study does not use standard operation procedure for equipment maintenance which led to the problems of management and maintenance. Hence, we suggest that the equipment maintenance management processes be sta
