abstract: one the most important problems in recent sensitive loads is the quality of voltage. for this challenge custom power devices are used in distribution systems. dynamic voltage restorer (dvr) is a custom power device that improves voltage, decrease power distortion, filter harmonics and balance distributed generations (dgs) with low voltage distribution system. in this paper, a new algo...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

We describe recent advances in theories and architecture that support performance guarantees needed for quality of service networks. We start with deterministic computations and give applications to integrated services, differentiated services, and playback delays. We review the methods used for obtaining a scalable integrated services support, based on the concept of a stateless core. New prob...

The environmental impacts arising from mining activities affect the air, water, and soil quality. Impacts may result in unexpected and adverse environmental outcomes. This study reports on the impact of coal production on sediment in Sydney region of Australia. The sediment samples upstream and downstream from the discharge points from three mines were taken, and 80 parameters were tested. The ...

The most important criterion for achieving the maximum performance in a wireless mesh network (WMN) is to limit the interference within the network. For this purpose, especially in a multi-radio network, the best option is to use non-overlapping channels among different radios within the same interference range. Previous works that have considered non-overlapping channels in IEEE 802.11a as the...

Capillary wireless sensor networks devoted to air quality monitoring have provided vital information on dangerous air conditions. In adopting the environmentallygenerated energy as the fundamental energy source the main challenge is the implementation of capillary networks rather than replacing the batteries on a set period of times that leads to functional dilemma of devices management and hig...

Local banking markets depict enormous variation in population size. Yet this paper finds that the nature of bank competition across markets is strikingly similar. First, markets remain similarly concentrated regardless of size. Second, the number of dominant banks is roughly constant across markets of different size; it is the number of fringe banks that increases with market size. Third, servi...

Quality management has become more and more important in the last couple of years. The user is faced with a multitude of methods such as Six Sigma, TQM or Theory of Constraints. Therefore quality managers are more and more engaged in the selection of an appropriate approach for achieving the quality goals as they have been defined. Due to the necessity of coordinating heterogeneous quality meth...

PURPOSE/OBJECTIVES To test an adapted end-of-life conceptual model of the geriatric cancer experience and provide evidence for the validity and reliability of the model for use in practice and research. DESIGN Nonexperimental and cross-sectional using baseline data collected within 24-72 hours of admission to hospice. SETTING Two hospices in the southeastern United States. SAMPLE 403 hosp...
