Digitization of the control loop for high frequency dc-dc switching converter are increasing the application areas of modern semiconductor based power system. This paper aims at detail modeling of buck converter design considering the ESR resistances and incorporates the optimized ADC converter, DPWM and PID compensator loop to enhance and stabilized the working of high frequency DC-DC switching converter...
This paper presents the nonlinear formulation for Functionally Graded Material (FGM) plates and shells using Semiloof Shell element. Results for buckling and vibration analysis of functionally graded plates and shells are reported.
Partially regularized technique is an extension based on interval constraint of minimum norm solution. Such techniques have shown good results on problems like Missing Data Recovery (MDR). The proposed use of partially regularized technique for the computer tomography (CT) image reconstruction is to investigate if the MDR concept can be used for few view projection data acquisition scenario. The motivation...
Panoramic stitching of static and dynamic scenes is a very important and challenging research area. For static scenes, number of approaches has been proposed so far. The result produced by these approaches provides great similarity between resultant panorama and input images with almost zero seam visibility. However for dynamic scenes, we have found that existing approaches are unable to overcome...
A novel spatio-temporal (ST) three dimensional (3D) adaptive filter bank has been proposed based on the optimization techniques. The proposed adaptive algorithm is defined to track the 3D broadband spatio-temporal plane wave signal. For designing such an adaptive 3D filter bank, the orientation of 3D broadband plane wave signal in frequency domain has been tracked and aligned to the direction of axis...
In this paper a nonlinear control has been designed using the dynamic inversion approach for automatic landing of unmanned aerial vehicles (UAVs), along with associated path planning. This is a difficult problem because of light weight of UAVs and strong coupling between longitudinal and lateral modes. The landing maneuver of the UAV is divided into approach, glideslope and flare. In the approach...
This paper illustrated the application of Levinpsilas transform in solving a system of equations arising in the method of moments solution. Numerical examples include the computation of charge on a conducting strip, current distribution on a thin wire antenna and scattering from a nanowire. Since the method is iterative, it does not require inversion of a matrix in the solution of the system of equations...
