Design and Fabrication of Magnetically Levitated Wind Turbine for Power Generation
-Vaishali A. Randive ; Prof. S. K. Malode
Magnetic levitation is a method by which an object is suspended above another object with no support other than magnetic fields. The electromagnetic force is used to counteract the effects of the gravitational force. Magnetic levitation is used to reduce the energy loss due to friction. This energy wasted in friction can be saved by maglev method. This thesis proposes a method to implement non-conventional source of energy for the generation of electricity. A vertical axis wind turbine is introduced by magnetic levitation technology to optimize the performance. The system utilize nature of permanent magnet as a replacement for ball bearings to levitate the turbine component and thus minimize energy losses while rotating, which is the major problem that faced by conventional wind turbine. Furthermore, the system can be suited in use for rural and urban areas of low wind speed regions. The selection of magnet materials in the design of wind turbine system will be discussed. A model of wind turbine is built to perform several tests such as starting wind speed, rotational speed at constant wind speed, and time taken to stop rotation completely. The results obtained will be compared with the model of conventional wind turbine. Power will then be generated with an axial flux generator, which incorporates the use of permanent magnets and a set of coils. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic pressure is used to counteract the effects of the gravitational and any other accelerations. Read More...

-Deependra Nayak ; Prof. Vinay Kumar Singh Chandrakar
The response of a concrete industrial building subjected to load and lateral blast masses was examined. INVENTOR is used for generating the 3D model. The finite element component package ALTAIR was wont to analyze with radially symmetrical boundary conditions. For the response calculations, transient structural analysis was simulated in STAAD PRO and for that a undulation within the sort of uniform pressure was applied. An explosion within or immediately nearby a building can cause catastrophic damage, on the building's external and internal structural frames, collapsing of walls, blowing out of large expanses of windows, and shutting down of critical life-safety systems, depending on the intensity of the blast. Loss of life and injuries to occupants can result from many causes, including direct blast-effects, structural collapse, debris impact, fire, and smoke. The analysis of structures subjected to blast pressure needs an in depth understanding of blast phenomena and also the dynamic response of varied structural parts. This provides a comprehensive summary of the consequences of explosion on composite structure. Read More...

The Effect of Filler on Asphalt Cement Mastics
-Ghanshyam Dhangar ; Mr P C Diwan
This study examines four types of industrial and by-product waste fillers, namely limestone dust (LSD), which was the reference filler; ceramic waste dust (CWD); coal fly ash (CFA), and steel slag mixture (SSD). The filler consisted of an aggregate (10% of total weight) with three proportions: 100% passing 75µm, 50% passing 75µm/20µm, and 100% passing 20µm. Comprehensive laboratory tests were performed to determine the impact of different types and particle sizes of fillers on the engineering and mechanical properties of fine mastics and stone mastic asphalt mixture. The results indicate that the application of industrial by-products used as fillers improves the engineering properties of stone mastic asphalt mixtures. The increased stiffness due to the addition of the filler is represented by an increase in the softening point, viscosity, stability, and resilient modulus, as well as a decrease in penetration. The optimum asphalt content increased with the decrease in filler particle size for LSD and SSD, and decreased for CWD and CFA. It was also determined that the filler type and particle size has a significant effect on the mixture properties. Among these three proportions, the samples prepared with the filler size proportion of 50/50 gave the best value in terms of stability, Marshall Quotient, and resilient modulus than the other filler size proportions.

Getting the Best Rules using Genetic Algorithm Variants
-Lobo L. M. R. J ; R. S. Bichkar
A large amount of transaction data gets stored on storage devices every day. To convert this huge amount of data into useful information we have proposed some data mining techniques which represent datasets (with the help of rules) to a maximum extent. A popular method to generate such rules is Association Rule Mining. The popular rule mining algorithm named Apriori algorithm can be used to generate these rules. However the efficiency and optimized set of rules can be achieved using Genetic algorithms and its variants. The present paper elaborates on a system developed to find all the possible optimized rules from the data set generated by Apriori algorithm using Genetic Algorithm and using its variants to improve the performance of the system by speeding up the time required for getting the results after scanning huge datasets. Experimentally a speedup of 1.67 using Parallel Genetic Algorithms and a speedup of 1.76 using Hierarchical Genetic Algorithms respectively as compared to using Simple Genetic Algorithms is generated by the system proposed.

-Vishal Acharya ; Renu Kumari; Nitin Patidar
A digitally controlled PGA with 46µW power dissipation and 1-40dB programmable voltage gain in 2dB steps is presented in this paper. It is best suited for low power applications. It has low input referred noise i.e. 2.9µV/√Hz, 3.4µV/√Hz and 1.8µV/√Hz at 1Hz, 50Hz and 200Hz respectively. The PGA has 3dB bandwidth of 20 KHz. It has PSRR that exceeds 84.5dB at all gain settings and is constant for entire 20 KHz bandwidth. In order to achieve linearity in programmable gain a new structure resistor array is proposed. The resistance is implemented by using floating active resistors which act as resistor. The advantage of floating active resistor is that they have small size and their resistance can be easily altered by changing the W/L ratios. In this work the values of floating resistor (rds) is between 180Ω-23KΩ to achieve desired gain and low power dissipation. This PGA is designed and simulated in 0.18µm technology. The simulation and layout results are obtained using Cadence’s Virtuoso and Sparta tool. Read More...

Pushover Analysis of Multistorey Building with Soft Story
-Priyanka Dnyandeo Raipure
The project work deals with the Reinforced Concrete Special Moment Frame that are used as a part of seismic force-resisting systems in buildings that are designed to resist earthquake. Beams, columns, and beam-column joints in moment frames are proportioned and detailed to resist flexural, axial and shearing actions that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. Special proportioning and detailing requirement results in a frame capable of resisting strong earthquake shaking without significant loss of stiffness or strength. These moment-resisting frames are called “Special Moment Resisting Frames†because of these additional requirements, which improve the seismic resistance in comparison with less stringently detailed Intermediate and Ordinary Moment Resisting Frames. The design criteria for SMRF buildings are given in IS 13920 (2002). In this study, the buildings are designed both as SMRF and OMRF, and their performance is compared. For this, the buildings are modeled and pushover analysis is performed in SAP2000. The pushover curves are plotted from the analysis results and the behavior of buildings is studied for various support conditions and infill conditions. The behavior parameters are also found for each building using the values obtained from pushover curve and is investigated. Read More...

Image Restoration Filters in Spatial Domain for Various Noise Density Ranges
-Smita Agrawal ; Sunil Kumar; Anurag Bajpai; Vivek Kumar
Image Restoration is an area of image processing that deals with the removal of noise by various filtering techniques. There are various filters that exist in literature for various types of noise. Most of them are specific to the noise type and particular noise ranges. These are classified into linear and non-linear filters. Linear filters are more suitable for gaussian noise removal even at higher noise densities (>30%) and at times for speckle noise removal, whereas non-linear filters are more suitable for impulse noise removal, especially at low and medium level densities. However, at higher noise densities, non-linear filtering efficiency generally gets degraded. In this paper, a comparative analytical treatment is done for six filtering methods, at medium to high noise densities, and the choice of the most suitable filter technique is determined for particular noise ranges. The noise and filter functions are implemented in MATLAB. Read More...

-Archana Gopinadhan ; Mr. J Santhosh
IRIS recognition is one of the most reliable techniques in biometrics for human identification. Iris recognition techniques have been used widely by governments, such as the Aadhaar project in India. This paper presents a biometric recognition system based on the iris of a human eye using wavelet transform. The proposed system includes three modules: image preprocessing, feature extraction, and recognition modules. The feature extraction module adopts the gradient directions (i.e., angles) on wavelet transform as the discriminating texture features. We present a new approach for detecting and matching iris crypts for the human-in-the-loop iris biometric system. Our proposed approach produces promising results on all the three tested datasets, in-house dataset. The identification result obtained using the EMD approach illustrates the success of its efficient use in iris recognition. A fast iris localization method like rectangular area method is used. Using this method, iris segmentation is performed in short time. Read More...

India, being a developing nation is experiencing major growth in its infrastructure. Concrete is the major component of this infrastructural boom. This has led to the requirement of good quality of concrete in very large quantities. This requirement can be fulfilled by the ready mix concrete batching and mixing plants. To fill the gap between the demand and supply of concrete a large number of RMC plants are coming into existence. The main objective of this study is to calculate the Time Management of an RMC plant, which will help an investor or any person or an organization to take investment decisions regarding an RMC plant. The study establishes the cash flow for the RMC plant helpful in investment and capital generation related decisions. The market has been surveyed and the realistic costs for operating and maintaining the RMC plant are collected as also the cost of commissioning and erecting the RMC plant are collected from the manufacturers. Transit mixers form an important component of the RMC plant and their cost of owning and operating form a major part of the Time Management of RMC. Based on the daily demand from some sites in the city of Mumbai, the number of transit mixers that would be required on the RMC plant to fulfill that demand has been simulated using Monte Carlo simulation. The Time Management of the RMC plant has then been calculated. Further with the help of this study the Time Management of any other capacity RMC plant can be calculated and based on requirements and capital availability, the economic option can be selected.

Management of Construction using Lean Technique
-Nikhil Patil ; Prof. S. S. Deshmukh
The Construction industry of India is an important indicator of the development as it creates investment opportunities across various related sectors. The construction industry has contributed an estimated US$ 308 billion to the national GDP in 2011-12 (a share of around 19%). The industry is fragmented, with a handful of major companies involved in the construction activities across all segments; medium-sized companies specializing in niche activities; and small and medium contractors who work on the subcontractor basis and carry out the work in the field. In 2011, there were slightly over 500 construction equipment manufacturing companies in all of India. The sector is labor-intensive and, including indirect jobs, provides employment to more than 35 million people. The Indian construction industry is also facing a severe resource setback in terms of skilled and semi-skilled man power. Though the above mentioned problems need noteworthy thought and time, it is crucial that increased emphasis is given to new project management strategies so that the Indian growth story doesn't meet a hasty end. After some research the medium and big firms need to look to the developed nations and also China for new strategies and implement them here. Read More...

To Study the Design Optimization of the Tie Rod with Mass Reduction using CAD/CAE Tools
-Toofan Singh ; Farman Khan; Gagandeep Singh Sandhu; Ravinder Singh
In the present work, a three dimensional model of a Car tie rod is prepared in CAD modelling tool SOLIDWORKS and imported into FEM assisted CAE tool, ANSYS. A proper description of FEM is also presented to describe the working of this technique. First of all the Failure analysis of the tie rod is done to determine the sensitive region of the tie rod and failing forces. The material assigned to the model is AISI 8620 alloy steel. The meshing of the tie rod is done and then proper boundary conditions are applied and the equivalent stress and deformation is calculated. The failure analysis shows that the highest stresses are produced at the edge of the threaded joint of tie rod and the under the compressive forces of 4205 N, the stresses surpass the compressive yield strength of the material and tend to fail the tie rod. The changes in the sensitive part of the tie rod are done in order to reduce the stresses induced in the tie rod. The fillets are added to the edge of the threaded joint of the tie rod and for each case, the structural analysis using same boundary condition and forces is done to determine the values of equivalent stress and mass of the tie rod. The compressive forces kept are 4200 N since this was the highest value at which tie rod remains safe during failure analysis. The modification is done only in the sensitive part of the tie rod. After the structural analysis of each case of change, it is found that the maximum stress reduction is 30.014 and the mass reduction percentage is 0.27 when compared to the original model.

WAP Approach Coded for Frequent Sequential Traversal Pattern Mining for Web Data
-Ms. Pratibha Pal ; Mr. Abhay Kothari
With the explosive growth of data available on the World Wide Web, discovery and analysis of useful information from the World Wide Web becomes a practical necessity. Web access pattern, which is the sequence of accesses pursued by users frequently, is a kind of interesting and useful knowledge in practice. Sequential Pattern mining is the process of applying data mining techniques to a sequential database for the purposes of discovering the correlation relationships that exist among an ordered list of events. Web access pattern tree (WAP-tree) mining is a sequential pattern mining technique for web log access sequences, which first stores the original web access sequence database on a prefix tree, similar to the frequent pattern tree (FP-tree) for storing non-sequential data. WAP-tree algorithm then, mines the frequent sequences from the WAP-tree by recursively re-constructing intermediate trees, starting with suffix sequences and ending with prefix sequences. An attempt has been made to modify WAP tree approach for improving efficiency. New Binary Coded WAP totally eliminates the need to engage in numerous re-construction of intermediate WAP-trees during mining and considerably reduces execution time. Read More...

Explosive Detection by Sensor
-Prakash Amarsingh Patil ; Dipak Khedkar; Ganesh Redde; Prasad Kulkarni; Jayashri Chopade
There is a need in the society for a fast and reliable detection of explosives because of their use in most terrorist attacks. Chemical sensors, especially fluorescent sensor, seem to fill the need in terms of cost, reliability and handling ability. The localization and detection of improvised explosive devices (IEDs) on the roadside is new issue encountered in the struggle against terrorism. A new method for detection and localization was proposed for IEDs based on magnetic signals. 3-axis fluxgate sensor array system is used for detection of the magnetic field produced around the body by the IED, as most of the IEDs have the ferromagnetic properties .Using this detected sensor data, the detection and localization of the IED can be computed by an appropriate method based on magnetic dipole model and nonlinear optimization algorithm. Sensitive and Selective detection of explosives is very important in countering terrorist attacks. High sensitivity and selectivity, combined with the ability to lower the cost of sensors using mass production, is essential in winning the war on explosives based terrorism. Nano sensors have the potential to satisfy all the requirements for a best platform for the trace detection of explosives. Read More...

-Lakshmi Prasanna Arasavilli ; S Sravanthi; M R V S G Guptha
The concrete is made with wastes which are freely available in present environment and named as eco-friendly concrete or Green concrete. This Green Concrete is an environmental friendly and the overall impact on the environment per ton of concrete is limited. Some of the environmental waste materials are fly ash, marble powder, ceramic, crushed stone dust, Blast furnace slag, copper slag, demolition wastes, rice husk ash(RHA) etc. It has been observed that 1.71 tons of CO2 is produced per ton of cement production causes environment pollution. Now we have to reduce the production of cement for better environment. This focus of study goes on cement replacements only. Lot of research work showed and over and above all eco-friendly concrete has greater strength and durability than the normal concrete and having low flexural strength. The research papers showed compressive and tensile strengths results only so, in practical way no one can using these environmental wastes in concrete. In another study using glass fibres in concrete to improve and increase the flexural strength. There are lot of research work and plenty of journals about using 1% optimum of glass fibres in concrete for increasing the flexural strength behaviour and increasing the load carrying capacity of structural members comparative with normal concrete. So this experimental research is about how to improve the flexural strength in eco-friendly concrete with adding of glass fibres and study the strength parameters. Read More...

Secret Common Randomness from Routing Metadata In AdHoc Networks
-Rashmi. S. K ; Ramya S Pure
Building up secret common randomness between two or multiple devices in a network lives at the root of communication security. In its most frequent form of key establishment, the problem is traditionally decomposed into a randomness generation stage (randomness purity is subject to employing often costly true random number generators) and an information-exchange agreement stage, which relies either on public-key infrastructure or on symmetric encryption (key wrapping). In this paper, we propose a secret common randomness for specially appointed network adhoc systems, which works by reaping haphazardness specifically from the network routing metadata, in this way accomplishing both pure randomness generation and (certainly) secret key understanding. Our algorithm relies on the route discovery phase of an ad hoc network employing the dynamic source routing protocol, is lightweight, and requires relatively little communication overhead. The algorithm is evaluated for various network parameters in an OPNET ad hoc network simulator. Our results show that, in just 10 min, thousands of secret random bits can be generated network-wide, between different pairs in a network of 50 users. Read More...

Performance of Active Power Filters and Their Applications for Power Generation Systems
-Pallaprolu Divya Reddy ; Ch China Veeraiah
Active filters have become a viable alternative for controlling harmonic levels in industrial and commercial facilities. However, there are many different filter configurations that can be employed and there is no standard method for rating the active filters. The compensation for harmonic and reactive currents becomes increasingly important owing to the wide use of power electronic equipment. Traditionally, passive LC filters have been used to eliminate line current harmonics and to increase the power factor. However, in practical applications these passive filters present many disadvantages, such as aging and tuning problems, series and parallel resonances and others. In order to overcome these problems, many compensated methods based on the technique of power electronics have been researched and developed recently, one of them is active power filters, which have gradually been recognized as a feasible solution to the problems created by nonlinear loads. They are used to eliminate the unwanted harmonics and compensate power factor by injecting equal but opposite compensation currents. An active power filter, a current source, connected in parallel with the nonlinear load, is controlled to generate the required compensation currents, so the main only needs to supply the fundamental current. Besides eliminate harmonic currents and compensate power factor, this kind of active power filter can keep the power system balanced under the condition of unbalanced and nonlinear loads simultaneously, if the compensation currents include harmonic, reactive, fundamental negative sequence and zero sequence currents. A detailed yet simple mathematical model of the active power filter, including the effect of the equivalent power system impedance, is derived and used to design the predictive control algorithm. The compensation performance of the proposed active power filter and the associated control scheme under steady state and transient operating conditions is demonstrated through simulations and experimental results.

An Improved Power Flow Analysis Technique
-Dr. Deepak P. Kadam
Reactive power optimization is important to power system stability and power quality. How to use the reactive power control method to improve the voltage level and decrease system loss is of value both in theory and application. The adjustment of generator voltages, transformer taps, shunt capacitors and inductors will control the reactive power distribution and affect voltage profiles and power losses. The objective is to find proper adjustments of these control variables that would maintain acceptable voltage profiles and minimize power losses. Reactive power optimization has commonly been formulated as a complicated constrained optimization problem with non-differentiable nonlinear objective function Reactive Power consumption increases losses in the system, which reduces the total system real power. Optimizing reactive power in the system can minimize total system real power loss. This can be done by optimally setting the terminal voltage of generating plant, transformer tap settings, output of compensating devices such as capacitor bank and synchronous condensers. Conventional Optimal Reactive Power Dispatch (ORPD) formulations utilize minimization of total system real power loss or voltage deviation as an objective to compute optimal settings of reactive power output or terminal voltage of generating plants, transformer tap settings and output of compensating devices. The present work has considered the setting of Flexible AC Transmission System (FACTS) devices as additional control parameters in the ORPD formulation and studies its impact on system loss minimization. Static models of FACTS devices consisting Static VAR Compensator (SVC) have been included in the present ORPD formulation. Read More...
