Now a days, Image Super resolution is one of the most important and challenging issue in the image processing area. Aim of Super resolution is to generate high-resolution image from single or multiple low resolution of the same scene or image. With single low resolution image it's very challenging to produce high-resolution image because a single low-resolution image contain the less information. Due to the ability of preserving edges, kind of method called TV (Total Variation)-based method was proposed as regularization function for some inverse problems. Due to ill-posed nature of problem, existing super resolution method which based on combine total variation regularization term including the Non Local Total Variation (NLTV) and Steering Kernel Regularization Total Variation (SKRTV) which takes the more execution time due to the non-local weight calculation. We propose the Example based Convolution neural network which consists of three layers namely convolution layer, max-pooling layer and reconstruction layer. Using Convolution neural network approach we achieved to reduce the execution time as well as increased the PSNR ratio. © 2016 IEEE.

The present work aims to study the possibility of replacing fine aggregate with a mixture of Poly Vinyl Carbonate (PVC) Powder and Glass Powder in manufacturing cement concrete. For this, experiments were carried out to measure and study fresh and hardened properties of the M25 grade of concrete with PVC powder and glass powder. The fine aggregates were replaced at dosages of 0%, 5%, 10%, 15%, 20%, 25%, and 30%. The physical properties (density, workability and water absorption), mechanical properties (flexural and compressive strength) and durability aspects (acid attack and alkalinity) were found and studied. Results indicate that the performance of the concrete in terms of all the above stated parameters is within acceptable limits as per the codes. The microstructure analysis reveals the fact that the glass and PVC particles have formed a good and even distribution across the concrete. The replacement dosages can be further increased and studied. © 2017 The Authors.

The paper presents seismic response of a five story building equipped with smart base-isolation system using Lead rubber bearing (N-Z) and MR-damper placed in between foundation and base of the building. Five types of building viz. fixed base building, base isolated building without MR damper, base isolated building with MR damper in passive off/on mode, and base isolated building with MR damper driven by Fuzzy logic controller, base isolated building with MR damper driven by Neural network are studied. The peak base displacement and top floor absolute acceleration for controlled and uncontrolled cases are evaluated for past four earthquake ground motion history. The result of the study shows that the ANN is found to be effective in reducing mean peak isolator displacement relative to the FLC and FLC is found to be effective in reducing normalized mean peak top floor absolute acceleration relative to the ANN. © 2017 The Authors.

The Performance Based Plastic design method uses pre-selected target drift and yield mechanism as performance criteria due to which total collapse of structure can be prevented. A fifteen storey Reinforced Cement Concrete frame was designed using the displacement based Performance Based Plastic Design (PBPD) method and currently used force based Limit State Design (LSD) method. The comparative seismic performance evaluation of the frames was then carried out by assessing the Response Reduction factor as well as the failure pattern. Results show that PBPD frame is found to have a higher response reduction factor as compared to the LSD frame. Also total collapse of the frame is prevented in the PBPD frame as hinges are formed in beams only. © 2017 The Authors.

The paper describes the behaviour of liquid storage slender and broad tanks isolated by the double variable frequency pendulum isolator (DVFPI). The DVFPI is a double sliding isolation system having elliptical sliding surfaces. The geometry and coefficient of friction of top and bottom sliding surfaces can be unequal. The governing equations of motion and energy balance equation of the tank-isolation system subjected to bilateral ground excitation are derived and solved in the incremental form. In order to investigate the behaviour of the DVFPI, the response is obtained under different parametric variations for a set of 20 far-field earthquake ground motions. Four different combinations of the DVFPI design cases having different isolator geometry and coefficient friction at top and bottom sliding surfaces are studied and the criterion to optimize its performance is proposed based on minimum responses and energy quantities. Further, influences of the initial time period, coefficient of friction and frequency variation factors at the two sliding surfaces and the tank aspect ratio are investigated. It is found that the performance of the DVFPI can be optimized by designing the top sliding surface with high initial stiffness relative to the bottom one and the coefficient of friction of both sliding surfaces to be equal for a slender tank whereas both surfaces should be designed with equal initial stiffness and coefficient of friction for a broad tank. © 2011 Elsevier B.V.

Floor-wash from dye finishing plant is a major source of color and wastewater volume for dyes industries. Batch electrocoagulation (EC) of simulated floor-wash containing Reactive Black 5 (RB5) was studied as a possible pretreatment option. More than 90% of initial 25mg/L of RB5 was removed at current densities of 4.5, 6, and 7.5mA/cm 2 in the presence of Na 2SO 4 and NaCl as supporting electrolytes; in less than one hour. Identical k obs (pseudo first-order reaction rate constant) values were obtained at initial pH of 3.74 for both electrolytes. However, at initial pH of 6.6, k obs values decreased in the presence of Na 2SO 4 and remained same for NaCl as compared to that at pH 3.74. Highest extent of decolorization and k obs values were obtained at initial pH 9.0 for both electrolytes. Under identical conditions, specific energy consumption (SEC) was almost half in the presence of NaCl (~29kWh/kgRB5) than that of Na 2SO 4. Vinyl sulfone (VS) was detected as one of the products of EC indicating reduction of azo bonds as a preliminary step of decolorization. Mechanism of decolorization with respect to various experimental conditions was delineated. Generation and accumulation of VS was dependent on initial pH and type of electrolyte. Results of this study revealed that EC in the presence of sodium chloride can be efficiently used as a primary treatment for decolorization of floor-wash containing RB5. © 2011 Elsevier B.V.

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.

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.

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.

EXPLORATION COLONIZATION RESOURCE EXTRACTION AND UTILIZATION OF MOON AND MARS (ECROMM) is a long term conceptual plan that may be feasible in near time with current technologies, has scope for international cooperation and would acquire self-sufficiency, require minimum supplies from Earth itself and would be able to recover the cost of the programme as well as supply precious mineral and other by-products back to Earth as a substantive economic returns of implementing the programme. Moon and Mars holds the answer to mankind's future in space. ECROMM is long term plan developed for future exploration, colonization, resource extraction and utilization of Moon and Mars. The following five mission phases are envisaged within this plan. Phase 1 : To Moon and Mars. Phase 2: Moon Colonization. Phase 3: Mars Human Space Exploration. Phase 4: Mars Colonization. Phase 5: Future Extension (Beyond Mars). All the phases involve robotic and human missions, except phase 1 which involves only robotic missions. Phase 2 and phase 3 are designed take place simultaneously so that overall mission time can be reduced. Moon and Mars has resources like helim-3, water, carbon dioxide from regolith, surface and atmosphere respectively. The concept involves extraction of resources like helium 3 and water from Moon and utilizing such resource for crew support and propulsion system. Mars has 95.35 % carbon dioxide in its atmosphere which can be converted to water, oxygen and fuel by simple chemical process. By phase 5 the colonies in Moon and Mars will be self-supporting and would require very less support from earth. ECROMM has scope of international cooperation of government and private space agency for developing different systems / components for the total mission. Participation of multiple countries will significantly reduce the cost, risk, and construction time of the system as observed in the construction of International space station (ISS) Phase 1 can be accomplished by utilizing current technology. For latter phases, we require advanced technologies that have not been fully developed yet, i.e. nuclear fusion engines, mining technology. Mining technology is the crucial part of this concept. Development of advanced mining system for Moon and Mars will reduce the cost of the mission as the resources on Moon and Mars will be utilized for propulsion system and crew support and supply precious minerals and by-products back to earth. The paper consist overview/summary of plan, the detailed plan is yet to be developed.
