Authors : Ashish K. Parashar, S. Atmapoojya, S.S. Rathore

Click Here For Abstract

Abstract : Seismic vulnerability analysis, an approach to get an estimate of the strong ground-motions at any particular site, is mainly intended for earthquake resistant designs or for seismic safety assessments. The hazard study usually attempts to analyze two different kinds of anticipated ground motions, “The Probablistic Seismic Hazard Analysis” (PSHA) and “The Detemininstic Seismic Hazard Analysis” (DSHA). A sincere effort is made herein to do seismic hazard analysis for Ballar Dam of Chattisgarh state . An attempt was made to compile the occurrence of past and recent seismic activities within 300 km radius, around the Dam site. Further the seismic hazard analysis was carried out at substratum level in terms of PGA using (DSHA), deterministic seismic hazard analysis technique The main benchmark and indicator involved in carrying out the hazard analysis is the correctness and completeness of the data which needs to be attained. The knowledge presented in this paper helps in evaluating the seismicity of the region around, Ballar Dam Site after statistical analysis of the database. Finally the results are furnished in the form of peak ground acceleration (PGA) for 50 Percentile & 84 Percentile with 100 years of Recurrence Period which can be used directly by engineers as fundamental considerations, for generating earthquake-resistant design of structures in and around Ballar Dam.

Click Here For Abstract

Abstract : Flyash is a waste produced from thermal power stations, which contributes to environmental pollution. It is waste materials that can be utilized in construction of roads and embankments. Disposal of a variety of wastes in an eco friendly way is the thrust area of today’s research. Randomly distributed fiber reinforced soils have recently attracted increasing attention in geotechnical engineering. These soils are prevalent as large tracts in many parts of the world. Many highway agencies, private organizations and researchers are doing extensive studies on waste materials and research projects concerning the feasibility and environmental suitability. It is necessary to utilize the waste affectively with technical development in each field. Attempts are made to investigate the stabilization process with laboratory model test tracks over expansive subgrade. Compaction, Shear and CBR tests were carried out in gravel/flyash materials with different reinforcement materials like waste plastics and waste tyre rubber with a view to obtain optimum percentage of reinforcement materials.

Title : Fabrication and Testing of an Solar Auto Service Station

Authors : P.Balashanmugam, G.Balasubramanian

Click Here For Abstract

Abstract : Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources. As such, it is vital that those in engineering fields understand the technologies associated with this area. My project will include the design and construction of a solar operated “SOLAR WATER SERVICING UNIT. This solar operated “Solar water servicing unit” is used to clean the light vehicles, especially two wheelers and delivers through a nozzle under high velocity. The air is compressed by a hand operated gate valve. The main components are water tank, nozzle, connecting tubes, one way valves and pneumatic air compressor. The solar panel is used to charge the battery and this charge is used to drive the D.C compressor to store the compressed air to the air tank.Solar tracking allows more energy to be produced because the solar array is able to remain aligned to the sun. This system builds upon topics learned in this course. A working system will ultimately be demonstrated to validate the design. Problems and possible improvements will also be presented.The pneumatic air is supplied to the portable service unit water tank by the compressor unit. The high pressure air is then delivered to the water tank through a hose. The water tank (25 liter) has a working capacity of 12 liter. The water tank is provided with a pressure gauge, safety valve, water inlet, and water outlet and air inlet. The pressure water in the tank is delivered through a nozzle at a high velocity. Solar panel has been used increasingly in recent years to convert solar energy to electrical energy. The solar panel can be used either as a stand-alone system or as a large solar system that is connected to the electricity grids. We are trying to consume more energy from the sun using solar panel. In order to maximize the conversion from solar to electrical energy, the solar panels have to be positioned perpendicular to the sun. Thus the tracking of the sun’s location and positioning of the solar panel are important. The goal of this project is to design an automatic tracking system, which can locate the position of the sun.

Title : Importance & Principle behind the Construction of Check Dam in Microwater-Shed Areas: A Critical Review

Authors : Anupam Kumar and Kumar Nikhil

Click Here For Abstract

Abstract : Conservation of water and checking soil erosion is central to the attainment of economic as well as financial sustainability of dry land and agriculture. Integrated Watershed Development Programme, which is proposed by the Government of India, is a major policy instrument for achieving this goal. The importance of watershed development as a strategy of agricultural and overall rural development in rain-fed areas has been recognized in India for the past several decades, and in the recent years has grown exponentially. Recent check-dams constructed over the micro watersheds like the ones in Bidar, Ahmedabad, Latur, Guna, Tumkur, spanning throughout the length and breadth of the nation, and its successful implementation shows its universal applicability. However, it is to be kept in mind that the implementation of check dam construction in a micro watershed based ecology dates back to the establishment of four dry farming research stations at Rohtak, Sholapur, Hyderabad and Bellary in early 30s, which led to the advancement in the recent technological augmentation.

Title : Investigation of vibrational properties of apple, lemon and orange branches under dynamic loads

Authors : Amin Yazdanmanesh, Davood Kalantari

Click Here For Abstract

Abstract : In the present research, investigation of vibrational properties of apple, orange and lemon tributaries is presented. Vibration of the samples were recorded by means of a digital video camera (Canon Sx 120IS) with 30 frames per second (fps). With reviewing the recorded frames in BsPlayer software, displacement of tip of the examined branches was measured and several vibrational characteristics were extracted or computed from the frames. Given the computed vibrational properties, a mathematical model is proposed for the free vibration of the apple, lemon and orange branches. Comparison between outputs of the model with the measurements indicates a good capability of the proposed model. The obtained results indicate that the orange branches have a significantly larger stiffness constant (k) and critical damping constant (cc) in compare to the apple and lemon branches.

Abstract : Indoles are very important compounds and found in many alkaloids of physiological importance. They are also found in seeds and plants such as orange and lemon. Para-hydroxybenzaldehyde dehydrogenase is an enzyme found in carrots, it can be found in the orchid. Indole reacts with p-hydroxybenzaldehyde in the presence of concentrated hydrochloric acid to form an orange color complex which has a maximum absorbance at 475 nm. The parameters affecting this reaction were studied in order to find the suitable conditions for the reaction to complete. The effect of acid concentration, reaction temperature and the amount of the reagent on the determination of indole- p-hydroxybenzaldehyde complex were investigated. The system requirements and the best conditions for complete determination are sequently studied. At the optimal conditions, 0.02% w/v p-hydroxybenzaldehyde, 3MHCl at30oC, was used for the determination of indole. Calibration graph was over the range from 0.5-5.00 μg ml-1. The detection limit was 0.08 µg ml-1 and the correlation coefficient was 0.999. Linearity was obtained with slope equals 0.119 and the intercept equals zero.

Title : Simulation of NLMS Adaptive Filter for Noise Cancellation

Authors : Kumudini Sahu, Rahul Sinha

Click Here For Abstract

Abstract : Adaptive noise Cancellation (ANC) is an alternative technique for estimation of noise & interference that corrupted the signal. The main objective of the noise cancellation is to estimate the noise signal and to subtract it from original input signal plus noise signal and hence to obtain the noise free signal. There is an alternative method called adaptive noise cancellation for estimating an input signal corrupted by an additive noise. The reference input is adaptively filtered and subtracted from the primary input signal to obtain the estimated signal. In this method the desired signal corrupted by an additive noise can be recovered by an adaptive noise canceller using NLMS (normalized least mean square) algorithm. Estimate the adaptive filter using MATLAB/SIMULINK environment. In the simulation, additive white Gaussian noise is added to the randomly generated information signal and efficiently reduced this noise with minimum or no error by using evolutionary computation with NLMS (normalized least mean square) algorithm.

Title : Tracking and Positioning of Mobile Systems in Telecommunication Networks

Authors : M Sushma Sri

Click Here For Abstract

Abstract : In todays fast generation the Mobile Positioning technology has became a vital role in area of research. The evolution to location dependent services and applications in wireless systems continues to require the development of more accurate and reliable mobile positioning technologies. Mobile Positioning in cellular networks will provide several services such as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is originated, and methods to predict the user movement inside a region. The major challenge to accurate location estimation is in creating techniques that yield acceptable performance when the direct path from the transmitter to the receiver is intermittently blocked. This is the Non Line of Sight (NLOS) problem, and it is known to be a major source of error since it systematically causes mobile to appear farther away from the Base station (BS) than it actually is, thereby increasing the positioning error. In this paper, we present a simple method for mobile telephone tracking and positioning with high accuracy. Through this we will discuss some technology used for mobile positioning and tracking.

Abstract : This paper describes the calibration of Isolation Current Transformer by two methods, by conventional method and by two comparator based calibration method. A conventional method has limitations that we get fixed ratios and hence can go up to lower value of 1A. The uncertainties of the calibration system are in the order of 0.005 % for the ratio error and 0.01 crad for the phase displacement of the current transformer at 50 Hz. The power comparator based measurements can be done at test currents from 10 mA to 160A.

Title : Electrical Transport and Magnetoresistance of Doped Polypyrrole

Authors : Tarek Fahmy, Moustafa T. Ahmed

Click Here For Abstract

Abstract : Different doped samples of conducting polypyrrole (PPy) are prepared electrochemically at different current densities. The electrical transport of conducting polypyrrole is investigated in a wide range of temperature starting from 4.2 K to 300 K. It is observed that, for samples prepared at high current densities, the electrical conduction is dominated mainly by the mechanism based on variable range hopping in a wide temperature range. On the other hand, the magnetoresistance of polypyrrole is investigated in the temperature range from 1.2 K to 4.2 K and magnetic field from H=0 T to H= 10.3 T. It is observed that, PPy sample is characterized by large positive magnetoresistance. This obtained large positive magnetoresistance in the insulating regime is typically expected for VRH conduction.

Title : Efficient reduction of leakage power in low power VLSI circuits using Sleepy Keeper Approach

Authors : Monisha.S, Priya.M, A. Upendra Raju, Uma.V

Click Here For Abstract

Abstract : Voltage Scaling in CMOS circuits will reduce the threshold voltage, however there is an increase in the sub threshold leakage current and hence static power dissipation. This increase in leakage power dissipation is a concern in VLSI design even for the most recent CMOS feature sizes. To reduce this power dissipation an approach called sleepy keeper is used for CMOS circuits. This approach uses two additional transistors along with the traditional sleep transistors. These additional transistors help to save a logic state during the sleep mode.

Authors : Oyeka I. C. A. and Nwankwo Chike H.

Click Here For Abstract

Abstract : This paper proposes a statistical method for the analysis of multiple responses or outcome data in case control studies including situations in which the observations are either continuous or frequency data. Test statistics are proposed for assessing the statistical significance of differences between case-control response score. The proposed methods are illustrated with some sample data. When there only three possible response options in which the proposed method and the Stuart- Maxwell test can be equally used to analyse the data, the proposed test statistic is show to be at least as powerful as the Stuart-Maxwell test statistic.
