reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...

introduction: green light photo selective vaporization of the prostate (pvp) is a minimally invasive method of treatment for clinical benign prostatic hyperplasia with fewer side effects. the aim of this study is to evaluate the safety, effectiveness and cost analysis of pvp compared with transurethral resection of prostate. methods: a systematic search was done in cochrane, trip database, medl...

Due to the high cost of disposable equipment and supplies, our university could not afford to provide each student with a sterile unopened kit. We searched for a way for students to have the experience of opening a kit and using it for the first time in a simulated learning environment. Our teaching team in the Adult Nursing course decided to let the students purchase a large packet of material...

In this paper, we propose a method for extracting an object region from an image. First, we investigate the properties of the Intelligent Scissors (IS) method, which has been proposed as a method for extracting contours. As a result, we verify that the IS method’s route search according to total cost requires multiple seed points to extract a complex contour. Next, we show that this problem can...

In this paper our goal is to nd the phonetic transcription of spoken utterances. We present a method which uses information extracted directly from the word-based search to compute the most likely phoneme sequence. Utterances are transcribed during recognition, so that the phonetic representation of the input is available after the search. Using this method, the computational cost of the word-b...

Supply chain management (SCM) is the term used to describe the management of the flow of materials, information, and funds across the entire supply chain, from suppliers to component producers to final assemblers to distribution (warehouses and retailers), and ultimately to the consumer. A case on the supply chain cost has been presented and the optimum cost is found out using numerical method....

The BSP model (Bulk Synchronous Parallel) provides a framework which permits the performance of a parallel algorithm to be predicted in a precise way. In this work we aim to analyse the main aspects of the BSP model studing three parallel preconditioners for the Preconditioned Conjugate Gradient Method. We also report the experimental results obtained on a IBM SP2. These results seem to lead to...
