In this paper we introduce an approach to increase density of field-effect heterotransistors in the framework of the three-stage differential amplifier. In the framework of the approach we consider manufacturing the amplifier in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that dopant and radiation defects should by annealed framework optimized scheme. We also consider an approach to decrease value of mismatch-induced stress in the considered heterostructure. We introduce an analytical approach to analyze mass and heat transport in heterostructures during manufacturing of integrated circuits with account mismatch-induced stress.
Muga silk is the most important composite material used in textile manufacturing in India. Muga silk is derived from the Muga silkworms, namely Antheraea assamensis Helfer. The golden yellow silk yarn is the fanciest because it has strange properties like being able to handle different textures well, being bright, and lasting a long time. Fibrin (a fibrous protein) and sericin (a globular protein) are the two most important protein units that make up silk. To make silk usable in the textile business, sericin, a gum, has to be cleaned off the surface of the silk. Generally, surface active agents are used in the extraction of sericin from silk material. The present research describes a comparison between the degumming activity of a natural surfactant saponin isolated from Sapindus laurifolia and Sapindus laurifolia-\(Na_{2}CO_{3}\) mixed system. The effect of the salt \(Na_{2}CO_{3}\) on the degumming ability of Sapindus laurifolia is systematically studied and reported. The surface morphology of the raw and degummed silk fibers is compared using scanning electron microscope.
Gas Tungsten Arc welding (GTAW) widely uses for many welding applications, especially for good quality welds in fabrication, manufacturing, and construction industries. Perfection level exhibits by the weld are associated with the entire volume of the weld, its profile, surface appearance, and microstructure and show the quality of that weld. Several controllable process parameters may affect the quality of weld in terms of weld shape, bead, imperfections, and desire mechanical/chemical properties. Therefore effect of some important parameters like current, travel speed, and gas flow rate on the final weld structure and its quality for SS TP304L material are studied through different experiments and analyses by using a design of experiment-based advanced statistical tools. Joints weld by using several levels of these parameters and then weld quality of these joints analyze in terms of ultimate tensile strength, and hardness. The optimization results of different statistical techniques compare to find the accuracy of this study. Moreover, the microstructure of final weldment welded based on optimal results is also analyzed. Therefore this study finds out the best welding conditions for the quality weld after optimizing these process parameters.
The optimal selection of a site for cement plant development is a multifaceted decision-making process that demands careful consideration of environmental, economic, and social dimensions. This research delves into the utilization of Circular Intuitionistic Fuzzy Soft Sets (CIFSS) as an advanced mathematical framework to enhance the precision and reliability of sustainable decision-making in cement plant site selection. The CIFSS approach adeptly manages the inherent uncertainties and ambiguities associated with evaluating potential locations, offering a comprehensive methodology for assessing various criteria. By embedding CIFSS within the context of sustainable development, this technique provides decision-makers with a robust and adaptable tool for identifying the most appropriate site, thereby ensuring long-term viability and minimizing environmental impacts. The results underscore the effectiveness of CIFSS in facilitating complex, multi-criteria decision-making in industrial site selection, underscoring its broader applicability in sustainable infrastructure planning.
