A tumor is an abnormal growth of new tissue that can occur in any of the body's organs. In recent years, there are many kinds of tumors are detected in the human body like Breast tumor, Bone tumor, Brain tumor, etc. Which are detected manually by doctors, but because of noise and low quality images of infected body parts, the tumor is not detected easily and is time consuming. Medical Imaging technique is used to create human body images for medical and research work. MRI is the best technique to acquire images as it has higher resolutions. The paper proposes an approach of detecting Enchondroma bone tumor from MRI images by using image processing, segmentation clustering techniques, i.e. K-means integrated with Fuzzy C-means clustering. From the experimental results we get 98% accuracy. © 2016 IEEE.

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.

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.

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.

In this paper, comparative analysis for feature extraction and recognition based on fast discrete Curvelet transform via wrapping and discrete Contourlet transform using Neural Network and Euclidean distance classifier is proposed. The pre processing is applied on the each image of dataset. Each image from the Training Dataset is decomposed using the fast discrete Curvelet transform and discrete Contourlet transform. The Curvelet coefficients as well as Contourlet coefficients of low frequency & high frequency in different orientation and scales are obtained. The frequency coefficients are used as a feature vector for further process. The PCA (Principal component analysis) is used to reduce the dimensionality of the feature vector. Finally the reduced feature vector is used to train the Classifier. The test databases are projected on Curvelet-PCA and Contourlet-PCA subspace to retrieve reduced coefficients. These coefficients are used to match the feature vector coefficients of training dataset using Neural Network Classifier. The results are compared with the results of Euclidean distance classifier for both the methods. © 2013 IEEE.
