Musculoskeletal Simulation and Evaluation of Support System Designs

The current technologies are predominantly attract the water resource management(WRM); if this water can not adequately utilizing for human activities, then several future problems are happening. Therefore super hydro controlling technology and it’s management systems are necessary. In this investigation, various water resource management methodologies, it’s merits and demerits are reviewed. The 2R-decision support system(DESS) implementation can change the conventional water management mechanisms, DESS addresses the engineering and non-engineering issues related to WRM system. The global WRM system designs and utilizations are facing many questionaries from experts. In India, there are many WRMs, but these are work for the nation, due to this limitation nations are facing many contemporary issues. Several methods have overcome these limitations but 2R-DESS answering the complete and accurate solutions to WRM. The advanced WRM system and its functionalities are verified on one example with the river basin agencies through DESS adequately. In this research work, for WRM calculating the various measures such as catchment area improvement, supply flow, upper flow, lower flow and acknowledgement of various effecting factors. The designed 2R DESS challenging the present WRM methodologies and results outperforms present technologies.

This paper describes the design and preliminary evaluation of the criteria for alerting drivers to a specific set of intersection hazards. The research is being conducted as part of the development of an intersection decision support (IDS) system that uses the sensing and computational technologies of infrastructure-based intelligent transportation systems. The IDS system under consideration is intended to help drivers avoid conflicts with oncoming traffic when they are making left turns under a permissive (i.e., unprotected) green signal. These conflicts account for a significant proportion of intersection crashes and are difficult to mitigate without imposing serious costs and burdens on intersection capacity associated with providing a protected left-turn signal cycle. The human factors and sensing issues that need to be considered in designing the system are discussed and are followed by a description of the logic used to define the gaps in opposing traffic that should be considered adequate for left-turn maneuvers. The simulation model used to evaluate alternative system designs is described, and sample results are shown for evaluation of the effectiveness of a warning under a relatively stressful scenario. The influence of alternative sensor configurations on the effectiveness of the warning is illustrated and indicates the importance of providing information about both the presence and speed of approaching vehicles sufficiently far from the intersection.

The most common problems encountered in sand casting foundries are related to sand inclusions, air, and oxide films entrainment. These issues can be addressed to a good extent or eliminated by designing proper running systems. The design of a good running system should be based on John Campbell’s “10 casting rules”; it should hinder laminar and turbulent entrainment of the surface film on the liquid, as well as bubble entrainment. These rules have led to the establishment of a group of components such as high and low placed filters (HPF/LPF) and standard gate designs such as the trident gate (TG) and vortex gate (VG) which are incorporated in well-performing running system designs. In this study, the potential of the aforementioned running system designs to eliminate air entrainment and surface defects has been investigated via means of computational fluid dynamics (CFD) simulations. The obtained results suggest that the use of filters significantly enhances the quality of the final cast product; moreover, all of the gating system designs appear to perform better than the basic running system (BRS). Finally, the five in total running and gating system designs have been evaluated with respect to their ability to produce good quality cast products (reduced air entrainment and surface defects) and their sustainability component (runner scrap mass).
