With the increasing demands of visual surveillance systems, vehicle & people identification at a distance has gained more attention for the researchers recently. Extraction of Information from images and image sequences are vary important for the analysis according to the application. This research proposes feature extraction and classification method using Wavelet. The DWT is used to generate the feature images from individual wavelet sub bands. The feature images constructed from Wavelet Coefficients are used as a feature vector for the further process. The Principal Component Analysis (PCA) /Fisher Linear Discrimination analysis is used to reduce the dimensionality of the feature vector. Reduced feature vector are used for further classification using Euclidian distance classifier and neural network Classifier. © 2010 IEEE. Source

This paper deals with the simultaneous application of thyristor controlled series capacitor based damping controller and power system stabilizer for stability improvement of dynamic power system. The adaptive neuro-fuzzy inference system and Levenberg-Marquardt artificial neural network algorithm are used to develop the control strategy for thyristor controlled series capacitor based damping controller and power system stabilizer. The power system stabilizer generates appropriate supplementary control signal to an excitation system of synchronous generator to damp the frequency oscillations and improves the performance of the power system dynamic. The performance of power system affected due to the system configuration and load variation. In order to achieve the appreciable damping, the series capacitor is suggested in addition to the power system stabilizer. Nonlinear simulations of single machine infinite bus system are carried out using the individual application of power system stabilizer and simultaneous application of power system stabilizer and thyristor controlled series capacitor. The comparison analysis between conventional and smart control strategies based controllers is demonstrated. Single machine infinite bus system is tested under various operating conditions and disturbances to show the effectiveness of proposed control schemes. © 2014 Elsevier B.V. Source

A numerical model of variably saturated axis-symmetric radial flow is employed to simulate and parameterize the gravity-delayed drainage, viewing it as the vertical accretion over falling water table. Numerical experiments are conducted to simulate the head fields at advancing discrete times as pumping is sustained at the assigned well. The head fields are invoked to generate the corresponding time series of water table elevation and the accretion rate over it. Employing these time series, the optimal structure/parameters of gravity-delayed drainage equation are estimated by the least-squares approach under a variety of hydrogeologic/geometric conditions. It is revealed that generally, a two-parameter gravity-delayed drainage equation reproduces parsimoniously the accretion time series. © 2015 American Society of Civil Engineers. Source

Earthquake response of slender and broad liquid storage steel tanks isolated with variable curvature friction pendulum systems (VCFPSs) is investigated under near-fault motions. The tanks isolated with VCFPS are idealised with three-degrees-of-freedom associated with convective, impulsive and rigid masses. The frictional forces mobilised at the interface of the VCFPS are assumed to be velocity independent. The governing equations of motion of isolated tank are derived and solved in the incremental form using Newmark's method. For comparative study, the seismic response of liquid storage tanks with the VCFPSs is compared with that of same liquid storage tanks isolated using the friction pendulum systems (FPSs). The seismic response of isolated liquid storage tanks is also compared with that of the non-isolated tanks. Further, a parametric study is carried out to critically examine the behaviour of liquid storage tanks isolated with the VCFPSs. The important parameters considered are the friction coefficient of VCFPS, the fundamental period at the centre of the sliding surface of VCFPS and the tank aspect ratio. It is observed that under near-fault ground motions, the VCFPS is quite effective in controlling the seismic response, viz. the base shear, the sloshing displacement and the impulsive displacement, of liquid storage tanks. © 2012 Copyright Taylor and Francis Group, LLC.

The mean interference effects between two rectangular buildings located in close proximity in a geometrical configuration of 'L' and 'T' plan shape are studied through wind tunnel test on 1:300 scale rigid models. The mean surface pressure distributions on all the walls of two buildings located in close proximity as well as in an isolated position are measured over an extended range of wind directions. The mean responses of pair of buildings namely, block-1 and block-2 subjected to interference effects are evaluated using experimentally obtained wind loads and, subsequently compared it, with the responses of a similar building in an isolated position. Effectiveness of upstream building location and wind orientation in changing the mean wind pressure distributions and responses of upstream and downstream building are also assessed. At wind incidence angle of 0°, presence of upstream block-1 reduces the mean along-wind displacement of block-2 of 'L' and 'T' shape arrangements up to 25% and 71% respectively as compared to that of corresponding block in an isolated position. However, the presence of upstream block-1 increases the maximum mean torque on block-2 of 'L' and 'T' shape arrangement up to 28%, and up to 88% respectively as compared to maximum mean torque developed on a similar block in an isolated position. © 2012 Korean Society of Civil Engineers and Springer-Verlag Berlin Heidelberg.
