Distribution Mechanism (distribution + mechanism)
Selected AbstractsAn adaptive load balancing scheme for web serversINTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 1 2002Dr. James Aweya This paper describes an overload control scheme for web servers which integrates admission control and load balancing. The admission control mechanism adaptively determines the client request acceptance rate to meet the web servers' performance requirements while the load balancing or client request distribution mechanism determines the fraction of requests to be assigned to each web server. The scheme requires no prior knowledge of the relative speeds of the web servers, nor the work required to process each incoming request. Copyright © 2002 John Wiley & Sons, Ltd. [source] The Impact of Surplus Distribution on the Risk Exposure of With Profit Life Insurance Policies Including Interest Rate GuaranteesJOURNAL OF RISK AND INSURANCE, Issue 3 2007Alexander Kling This article analyzes the numerical impact of different surplus distribution mechanisms on the risk exposure of a life insurance company selling with profit life insurance policies with a cliquet-style interest rate guarantee. Three representative companies are considered, each using a different type of surplus distribution: a mechanism, where the guaranteed interest rate also applies to surplus that has been credited in the past, a slightly less restrictive type in which a guaranteed rate of interest of 0 percent applies to past surplus, and a third mechanism that allows for the company to use former surplus in order to compensate for underperformance in "bad" years. Although at the outset all contracts offer the same guaranteed benefit at maturity, a distribution mechanism of the third type yields preferable results with respect to the considered risk measure. In particular, throughout the analysis, our representative company 3 faces ceteris paribus a significantly lower shortfall risk than the other two companies. Offering "strong" guarantees puts companies at a significant competitive disadvantage relative to insurers providing only the third type of surplus distribution mechanism. [source] Distributive mixing in a single-screw extruder,evaluation in the flow directionPOLYMER ENGINEERING & SCIENCE, Issue 10 2001Syang-Peng Rwei This study investigates distributive mixing in the flow direction for a single-screw extruder. WIth a custom-designed transparent extruder, an Image Analysis System, and a newly defined parameter, i.e., distribution index, the distribution mechanism is thoroughly examined with respect to various processing conditions or screw designs. Experimental results indicate that the longitudinal distribution can be enhanced with an increasing RPM, a longer metering section, or a decreasing diameter of the die. However, a plateau region occurs when an optimum condition exists for the RPM and the length of the metering section. In addition, an extruder modified with a barrier, pin-elements, or high helix angle performs better in the longitudinal mixing than the conventional one. Our results further demonstrate that leakage flow significantly enhances mixing in the flow direction. [source] Message and messenger: The carrier effect on judgments of credibilityPROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2008Paul Aumer-Ryan When examining the ways in which individuals evaluate the credibility of information sources, it is easy to assume that these judgments are based solely on the quality of the information being presented. The study described here questions this assumption by establishing a link between the quality of the interface (rather than the content) and perceived credibility. Essentially, interface design and the "form" of information (the messenger) can negatively impact the perceived quality of the "content" of information (the message). This study tests the hypothesis that individuals searching a poorly designed digital library will perceive the contents of the collection as less authoritative and credible than a digital library with a superior interface. This focus on interface design illuminates one of the methods by which individuals evaluate new or poorly understood information: by examining the quality of its distribution mechanism. Generally speaking, this research is an indication of how individuals are prone to the carrier effect, allowing features of the messenger (the interface) to affect the perception of the message (the digital library content). [source] Programming scientific and distributed workflow with Triana servicesCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 10 2006David Churches Abstract In this paper, we discuss a real-world application scenario that uses three distinct types of workflow within the Triana problem-solving environment: serial scientific workflow for the data processing of gravitational wave signals; job submission workflows that execute Triana services on a testbed; and monitoring workflows that examine and modify the behaviour of the executing application. We briefly describe the Triana distribution mechanisms and the underlying architectures that we can support. Our middleware independent abstraction layer, called the Grid Application Prototype (GAP), enables us to advertise, discover and communicate with Web and peer-to-peer (P2P) services. We show how gravitational wave search algorithms have been implemented to distribute both the search computation and data across the European GridLab testbed, using a combination of Web services, Globus interaction and P2P infrastructures.
