This research introduces an advanced forging method to produce the door frame of the wind turbine tower. The advantage of the new forging method is the increase of raw material utilization ratio and the energy saving. In the conventional method, the door frame is hot forged with a hydraulic press and machined out lots of material because of the big difference between forging shape and final mac...

Nowadays power consumption has become a major concern in many areas. One of them is scheduling. Scheduling is frequently required in parallel systems (Distributed System, Embedded System and Multi -core System). There are various parallel systems in which some are hand held device such as laptop and some other such as distributed and embedded system that required energy saving for long life, be...

I n the burn-in test of three-phase on-line unintermptible power supply(UPS) system, R. L. C. is usually used as a load in conventional method. For saving energy and decreasing the test cost of UPS, the energy feedback method is proposed to apply the test o f the on-line UPS. In this method, the utility system is used instead of a load. A voltage regulator is used in parallel operation to turn ...

In a previous published work, the lowest entropy for lossless encoding of the standard image " Lena " is found to be 5.311 bpp [3]. In this paper, we design an optimal filter using the Hybrid method approach that will give lower entropy of 4.198 bpp for the same image with saving of 21.22% and with saving in computation complexity and encoded sample of 32% and 20%, respectively than that in [3].

The increasing energy consumption levels of buildings within Europe call for controlled and improvements to savings efficiency effective regulations. However, many aging energy-inefficient require energetic retrofitting that can employ various façades solutions insulation materials. selection the most sustainable options in each situation therefore requires a decision-making methodology be used...

Abstract Photovoltaic irrigation has been widely used in many areas without conventional energy sources. In order to solve the problem of unstable operation and poor uniformity caused by diurnal variation solar radiation, a photovoltaic direct-drive water-saving system with automatic regulation was proposed. By using control technology method zonal rotation irrigation, all electric generated pa...

money and the way people spend it may cause lots of tension among family members; therefore, it is important to concentrate on money and the way it is spent. this article aims to address how women and men treat money as well as their differences and similarities. a mixed method (field research and survey) was designed to answer this question. qualitative data was gathered by using semi structur...
