Unmanned Aerial Vehicle become popular and very useful today. Unmanned Aerial Vehicle types have fixed wing UAV and rotary wing UAV. Among rotary wing UAV, helicopter type is chosen to implement the mathematical model for UAH. Since these helicopter mathematical model is very complex and inflexible, simple model “minimum-complexity helicopter simulation math model” (MCHSMM) is used to develop a non-linear mathematical model R-50 helicopter for this work. This modeling consists of three blocks: (1) Rigid body dynamics, (2) Force and torque dynamics, and (3) Flapping and thrust dynamics. Each of these are implemented in MATALB SIMULINK. There are four control inputs: ulat (lateral control input), ulong (longitudinal control input), ucol (collective control input) and uped (pedal control input). By alternating positive, negative, and zero to four control inputs, the resultant responses of positions, Euler angles, translatory velocities, angular velocities and flapping angles are simulated
This paper proposes a unique standalone hybrid power generation system, applying advanced power control techniques(APC), fed by four power sources: wind power, solar power, storage battery, and fuel cell, and which is not connected to a commercial power system One of the primary needs for socio-economic development in any nation in the world is the provision of reliable electricity supply systems. This work is a development of an indigenous technology hybrid Solar –Wind and fuel cell Power system that harnesses the renewable energies in Solar- Wind and fuel cell to generate electricity. Here, electric DC energies produced from photovoltaic and wind turbine systems are transported to a DC disconnect energy Mix controller. The controller is bidirectional connected to a DC-AC float charging-inverter system that provides charging current to a heavy duty storage bank of Battery and at the same time produces inverted AC power to AC loads. This paper focuses on the modeling and simulation

Abstract- The rise in global oil demand along with current environmental crisis; global warming and climate mitigation has been a serious issue. Thus, the need for an alternative fuel from renewable resources that promotes sustainability is vital to replace our dependence on fossil fuel. High sugar content in Oil Palm Frond Juice (OPFJ) indicates its potential as a feedstock in ethanol fermentation. Two strains of Saccharomyces cerevisiae; SA79 and HC10 are screened for high fermentation efficiency. Percentage yield bioethanol revealed that S. cerevisiae HC10 (55.72%) was proven a better strain than S. cerevisiae SA79 (43.19%). A growth profile of S. cerevisiae HC10 was performed in 60 h time period with 6 h interval sampling time. Specific growth rate (µ) and doubling time (td) of 0.037h-1 and 18.7h, respectively shows that S. cerevisiae HC10 fermentation of OPFJ is industrially applicable. In OPFJ fermentation, S. cerevisiae HC10 shows a much better yield (79.77 %) and thus an optim
