Internet traffic at a given web server often increases sharply within a short time as the number of Internet users increases. This phenomenon is known as a flash crowd. When flash crowds occur in the web server, the response rate decreases, or the web server may crash as the load increases. We propose a load reduction system that prevents excessive accesses to the web server in order to stably deliver content without having to enhance the performance of the web server. In the proposed system, the web server detects flash crowds by monitoring the number of requests and changes its content delivery system. To limit excessive accesses, the web server redirects requests to other clients that hold the content in their cache when flash crowds occur. We implemented the proposed system and verified its efficiency through experiments.

In breast thermography diagnostic, proper detection and segmentation of the areola area as well as detection of breast boundaries present the biggest challenge. As the boundaries of breasts especially in the upper quadrants are usually not present, this produces a great deal of challenge to segment breasts automatically. Many approaches have been developed to segment the breast in the past such as Snakes, Active Contours and Circular Hough Transforms, but these methods fail to detect the boundaries of the breast with the required level of accuracy especially the upper boundaries of the breast. By utilizing most recent segmentation method which is Random Walkers, the breast can be segmented accurately which in turn will increase the accuracy and the reliability of computer aided detection/diagnosis systems.

One of the most widespread techniques to evaluate various aspects of a manufacturing system is discrete-event simulation (DES). However, building a simulation model of a manufacturing system is a difficult task and needs great resource expenditures. Automated data collection and model buildup can drastically reduce the time of the design phase as well as support model reusability. Since most of the manufacturing systems are controlled by low level controllers (e.g., PLCs, CNCs) they store structure and control logic of the system to be modeled by a DES system. The paper introduces an ongoing research of PLC program processing method for automatic simulation model generation of a conveyor system of a leading automotive factory. Results of the validation process and simulation experiments are also described through a case study.
Current methods that evaluate the functions of masseter muscles (MM) are not suited to fully describing their functional roles. The aim of this study was to develop a method to quantify the deformations of MM in simul...

Morphological operators are generalized to lattices as adjunction pairs (Serra, 1984;Ronse, 1990;Heijmans and Ronse, 1990;Heijmans, 1994). In particular, morphology for set lattices is applied to analyze logics throug...
