A flying wing possesses no definite fuselage and no horizontal tail surfaces resulting in lesser drag surfaces, a larger wing area with a better range and endurance as compared to a conventional unmanned aerial vehicle (UAV). The present work explores an efficient and stable flight of a flying wing UAV at a lower Reynolds number using backward facing step wing profile. Numerical simulations for flow...
In this paper, we investigate a campus wide Wireless Local Area Network (WLAN) over a period of one month with the help of an advanced training system. Traffic characteristics and analysis has been performed based on the users` connectivity and their traffic behavior in a WLAN environment. The obtained results predict the users` traffic intensity in different time slots of the day and different days...
In this paper, we develop a reduced-order model of the torque produced by a vertical-axis wind turbine (VAWT) at different tip speed ratio (TSR). We numerically simulate the flow past a three-bladed Darrieus H-type VAWT to compute overall torque acting on the turbine. We then perform spectral analysis to compute the dominant frequencies and their interaction. Numerical results are used to analyze...
This paper presents a novel design of a three-degrees-of-freedom parallel manipulator. This manipulator has a crank arm type actuator instead of linear actuator, which is moved by means of servo motors. It has two degrees of orientation (Pitch and Roll) and one degree of translatory motion (Heave). Design is based on crank arm type actuator which can reduce the manufacturing cost without compromising...
