Improving Long Run Marginal Cost based Pricing along with Extended Benefit Factor method for Revenue Reconciliation of Transmission Network in Restructured Power System
Abstract : There are several methods to cover the costs of a transmission system and distribution networks. These methods are divided into either incremental or marginal approaches, which can be either long-term or short-term. The main difference between the incremental and marginal approach is how to calculate the cost of using the network. In the incremental approach, simulation and in the ma...
متن کاملA Cost-Bene t Scheme for High Performance Predictive Prefetching
High-performance computing systems will increasingly rely on prefetching data from disk to overcome long disk access times and maintain high utilization of parallel I/O systems. This paper evaluates a prefetching technique that chooses which blocks to prefetch based on their probability of access and decides whether to prefetch a particular block at a given time using a cost-beneet analysis. Th...
متن کاملReducing File System Latency using a Predictive Approach
Despite impressive advances in file system throughput resulting from technologies such as high-bandwidth networks and disk arrays, file system latency has not improved and in many cases has become worse. Consequently, file system I/O remains one of the major bottlenecks to operating system performance [10]. This paper investigates an automated predictive approach towards reducing file latency. ...
متن کاملDesign and Implementation of a Predictive File Prefetching Algorithm
We have previously shown that the patterns in which files are accessed offer information that can accurately predict upcoming file accesses. Most modern caches ignore these patterns, thereby failing to use information that enables significant reductions in I/O latency. While prefetching heuristics that expect sequential accesses are often effective methods to reduce I/O latency, they cannot be ...

Recently, the quality and safety of organic products is the topic of prime concern. While this demand increases since consumer considers organic products are healthier and harmless than conventional products. In the country like India, organic agricultural is not novel and are effectively performs in varied climates such as tribal mountains, mountainous areas and rain-fed zones of the country. ...
