Our aim was to assess the characterization of a pre stressed member if it was?to be under the Load effects of post compressing a bar with post tensioned method through hydraulic jacks as the reinforcements in the tensioned zone of conventional PSC bridge were to be compressed in order to induce internal tensile stress similar to internal compressive stresses developed due to conventional post tensioned design. The results ultimately concluded that post compressing a Slender bar by a pre stressing force in the compression zone by a value equal to 0.1?-?0.7 times the pre stressing force in the tension zone would eventually lead to cancelling out of tensile and compressive stresses, thereby forming the desired section which is comparatively smaller in size but can account for sustainability. The anchorage at the top end was?provided by special slender steel rods to eliminate the compressive stresses. All the dead loads?were?counteracted by the action of prestress and the bridge section was able to carry only live load which is deduced through examples in the article.展开更多

Quantum-dot cellular automate (QCA), single electron tunneling (SET), tunneling phase logic (TPL), spintronic devices, etc., are some of the nanotechnologies that are being considered as possible replacements for CMOS. In these nanotechnologies, the basic logic units used to implement circuits are majority and/or minority gates. Several majority/minority logic circuit synthesis methods have been proposed. In this paper, we give a comparative study of the existing majority/minority logic circuit synthesis methods that are capable of synthesizing multi-input multi-output Boolean functions. Each of these methods is discussed in detail. The optimization priorities given to different factors such as gates, levels, inverters, etc., vary with technologies. Based on these optimization factors, the results obtained from different synthesis methods are compared. The paper also analyzes the optimization capabilities of different methods and discusses directions for future research in the synthesis of majority/minority logic networks.展开更多
