This paper presents a parallel stabilized mixed Galerkin method for three-dimensional steady-state Darcy flow using OpenMP for shared memory architecture. In finite element problems, the computational complexity increases with increasing number of elements needed for large and complex geometry. Shared memory architecture offers a platform for solving such large and complex problems for practical applications...
The aim of this paper is to minimize the unwanted disturbance occurred in a wheeled armored vehicle during firing. An unwanted yaw moment occurred at the Center of Gravity (CG) of the armored vehicle caused by the impulse force generated during firing. This firing force tends to create instability conditions for the armored vehicle during firing. Therefore, an active safety system known as Active...
This paper proposes a neural network control scheme of a DC-DC buck-boost converter using online learning method. In this technique, a back propagation algorithm is derived. The controller is designed to stabilize the output voltage of the DC-DC converter and to improve performance of the Buck-Boost converter during transient operations. Furthermore, to investigate the effectiveness of the proposed...
Low noise amplifier (LNA) is used to amplify the received low power RF signals. A narrowband LNA is designed at the center frequency of 12.7 GHz with a gain of 10 dB, bandwidth of 72 MHz and noise figure of 3 to 4 dB. The design methodology required the analysis of the transistor, stability check and proper matching network selection for input and output. Ideal microwave amplifier equations are used...
