We carry out the asymptotic analysis of the following shape optimization problem: a given volume fraction of elastic material must be distributed in a cylindrical design region of infinitesimal cross section in order to maximize the resistance to a twisting load. We derive a limit rod model written in different equivalent formulations and for which we are able to give necessary and sufficient c...

The radiosity method is a simulation method from computer graphics to visualize the global illumination in scenes containing diiuse objects within an enclosure. A variety of realizations (including parallel approaches) were proposed to achieve a high eeciency while guaranteeing the same accuracy of the graphical representation. The hierarchical radiosity method reduces the computational costs c...

The radiosity method is a global illumination method from computer graphics to visualize light in scenes of diiuse objects within an enclosure. The hierarchical radiosity method reduces the problem size considerably but results in a highly irregular algorithm which makes a parallel implementation more diicult. We investigate a task-oriented shared memory implementation and present optimizations...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study, the effects of concentrate of smoked and sun dried raisin were investigated at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread. Results showed that addition of smoked and sun dried raisin improved quality a...

A modified plate dialyser (Rhone-Poulenc) was used 318 times to concentrate ascites for reinfusion in 210 patients, most of them having longstanding ascites refractory to diuretic treatment. The advantages of this method of treatment are its rapidity and efficacy, ascites being reduced in a mean time of 21±13 hr. Hyponatraemia is easily corrected by a sodium load during reinfusion. There was im...

Prosthodontic practice should always concentrate on procedures that prevent the excessive loss of jaw bone and those that contribute in maintaining the alveolar ridge height. Overdentures are one such option wherein roots prevent alveolar bone resorption, provide better load transmission, maintain sensory feedback and achieve better stability of denture with emphasis on psychological aspect of ...

We describe a hierarchical learning approach for effective coordination in repeated games based on a commonsense decomposition of the “coordination problem”. In contrast to most other research on mechanism design and game-learning, we concentrate on breaking down the top-level problem into simpler learning tasks concerned with learning (i) utility functions, (ii) best-response strategies and (i...

Feeding on saline marine foods may be especially challenging for passerine birds that lack functional salt glands and have a limited ability to concentrate urine. To reduce the salt load imposed by consumption of marine food these birds may select food with low salt contents and/or increase their intake of freshwater. The genus Cinclodes is particular among passerines because it includes specie...

Problem statement: With the growing popularity of clustering application combined with apparent usability, the single system image is in the limelight and actively studied as an alternative solution for computational intensive applications as well as the platform for next evolutionary grid computing era. Approach: Existing researches in this field concentrated on various features of Single Syst...
