This paper describes the system analysis, modeling and simulation of a Hydraulic Servo System (HSS) for hydraulic mini press machine. Comparisons among linear output feed back PID control, Fuzzy control and Hybrid of PID and Fuzzy control are presented. Application of hybrid controller to a nonlinear is investigated by both position and velocity of the hydraulic servo system. The experiment is based on an 8 bit PIC 16F877 microcontroller, and the simulation is based on MATLAB Simulink. Simulation and hardware experimental results show that the hybrid controller gave the best performance as it has the smallest overshoot, oscillation, and setting time.

Airport’s serving a tourist destination is an essential counterpart of the tourist demand supply chain, and their productivity is related to the region’s attractiveness and is enhanced by the air transport business. In this paper, the evaluation framework in order to prioritize the scheduled flights connecting two tourist airports is introduced, taking into consideration their available yield seats. By adopting a systemic approach, the arrivals from an airport that its connectivity is heavily depended on the departures of another airport are reviewed. The methodology approach, based on inventory control theory and the numerical example, promotes the use of the modeling formulation. The results would be essential for comparison and exercising to other similar cases

The issue of economic growth and development is one of the fundamental concerns of humankind. It is therefore necessary to find solutions so that people can have access to a greater diversity of goods and services, as well as better standard of living and well-being. Since ancient times, humankind has been warned about the scarcity of the resources but even with this information, they still take unreasonable measures with irreversible effects. The recent past gives us evidence that Sustainable Development is not only a practice of corporate social responsibility to gain a competitive edge, but also a necessity to meet the needs of future generations. The strength of the economic element cannot overlap with the balance of social and environmental dimensions. Having this is mind, the challenges are vast, as they are from all and for all citizens, since they are increasingly participating in building their futures, which require an awareness of a common destiny and the progressive construction of a world community

This paper first analyses the development trend of residents’ consumption Henan province from 2009 to 2016. Then the grey prediction model GM (1, 1) is applied to predict the change trend of residents’ consumption of Henan provinc. Finally, the paper puts forward some suggestions on the upgrading of the consumption structure of urban residents

The objectives of the paper are to conduct an investigation into the reaction force generated by the impact of a jet of water onto various target vanes and to compare between experimental and theoretical forces which are exerted by the jet. The procedure for this experiment is to bring the weight cup in the initial position by applying weight when the flow rate is varied. It can be possible to repeat the same experiment by changing different target vanes. Moreover, the effect of different target vanes can be seen at a constant flow rate by changing the type of target vanes and applying different amounts of weights to bring the weight cup in the initial position. The vanes used in this experiment can be categorized into four geometries. Flat, inclined, spherical and conical vanes are used for this experiment. Experimental and theoretical forces and the percentage of error can be calculated in this experiment. Here, the theoretical forces are depended upon weights applied on the weight cup and the experimental forces are depended on flow rate, nozzle exit velocity, impact velocity and shape of the vanes.

Corporate governance is about building credibility, ensuring transparency and accountability as well as maintaining aneffective channel of information disclosure that would foster good corporate performance. Corporate governance is the extent to which companies are run in an open and honest manner is important for overall market confidence. Corporate governance describes all of the devices, institutions, and mechanisms by which corporations are governed. The basic objective of the study is to analyze the level and structure of corporate governance in Nepal and determine its effects on financial performance in commercial banks of Nepal. Descriptive research design has been followed and multistage sampling method is used. Both primary as well as secondary data have been used to collect the information. It is found that corporate governance has played the significant role to keep the corporate governance in Nepalese commercial Banks.
