Diversity Techniques for Improving the Bit Error Rate in Wireless Communication
-Mallikarjun Dheshmuk ; T.Y.Melligeri
One of the major drawbacks of one branch communication is poor performance, in terms of BER (bit error rate). In order to improve the performance of wireless communication system, we propose diversity techniques. This new scheme does not require any bandwidth expansion or any feedback from the receiver to the transmitter and it is computationally feasible. Fading can be mitigated by using diversity. Diversity techniques are broadly classified in to antenna, frequency and time diversity. This paper reveals how the antenna diversity can be used for obtaining better BER. Read More...

Emerging Nanotech Applications in the Oil Industry
-JAVED MOHAMMED
With the introduction of nanotechnology, energy industries envisage a potential revolutionary change in the field of exploration, development and production. Research by universities into such areas as nanosensors, nanomarkers and nanobots to provide valuable data regarding the reservoir are of great focus due to their large potential return on investment, but have yet to yield substantive products. By contrast, efforts into drilling applications of nanotechnology such as drilling fluids are less known. Nanotechnology can revolutionize the additive properties by tuning particle characteristics to meet certain environmental, operational and technical requirements. Nano-technology produces nanomaterials that are ultra-fines in nature, usually smaller than ordinary micro particles and thus has very high specific surface area with enormous area of interactions. Recent research has indicated that nanomaterials have unique properties for a broad range of applications in the field of oilfield exploration and drilling , where fluid loss control, borehole stability, cementing quality of a well, remediation of damaged reservoirs, hydrocarbon recovery efficiency, oilfield wastewater treatment, high-temperature tolerance and viscosity modification are of interest. This paper presents an extensive literature review of assessing the applications of nanotechnology and nanomaterials in the field of oilfield exploration and drilling, investigating the existing problems in the application of nanomaterials in oilfield exploration and drilling , and evaluating the potential technical and economic benefits that nanotechnology and nanomaterials might provide to petroleum development and production. This paper will also discuss results from projects which utilize carbon nanotubes (CNT), nanosilica and other nanochemistries to achieve and enhance the performance of drilling fluids. Read More...

Risk Management Model for Residential Real Estate Project
-Parekh Varunkumar Jagdishbhai ; Mr. Hiren A. Rathod
For years, many research studies have focused on real estate projects for the risk reduction and increase the output from the real estate industry with the help of following complete risk management. However, Real estate industry is having projects which are very intricate in nature, where uncertainties & risks raise from different sources. In this article I consider the presence of risk in real estate industry two scenario, one is Optimistic Scenario and other is Pessimistic Scenario of seasonal type that affects some of the activities that comprise the project. I discuss how the project risk can be affected by such uncertainty, depending on the start date of the project. An effective and efficient risk management approach requires a proper and systematic methodology and, more importantly, knowledge and experience. This paper addresses the problems of risk management in construction projects using a knowledge-based approach, and proposes a methodology based on a three-fold arrangement that includes the modeling of the risk management function, its evaluation, and the availability of a best practices model. A major preliminary conclusion of this research is the fact that risk management in construction projects is still very ineffective and that the main cause of this situation is the lack of knowledge. It is expected that the application of the proposed approach will allow clients and contractors to develop a project’s risk management function based on best practices, and also to improve the performance of this function Read More...

Deflection Estimation of Varying Cross Section Cantilever Beam
-Prof. Naik Sanjeev B. ; Badadal Raghavendra R.
Everyone is familiar with deflection of beams with uniform cross section. In actual practice we come across mechanical shafts with variable cross section. In most of practical cases, it is necessary that a beam should be not only strong enough for its purpose, but also that it should have required stiffness, that is; it should not deflect from its original position by more than a certain amount. Very often stepped simply supported shafts, stepped cantilever shafts are introduced in the machines. It becomes difficult to estimate deflection for varying cross section beams. This paper presents a method to estimate deflection of such kind of beams. A tube inside a tube is considered as a cantilever beam and studied. The method introduced aims at simplifying the calculation. Two standard methods are also adopted to estimate deflection. Results of new method are compared with those of standard method. Read More...

Helically Coiled Heat Exchanger Heat Transfer Analysis using Fluent 14.0
-Madhuri Madhukar Tayde ; Jeevan Vinay Wankhade; Shylesha Channapattana
Enhancing the heat transfer by the use of helical coils has been studied and researched by many researchers because the fluid dynamics inside the pipes of a heat exchangers offer certain advantages over a straight tubes, shell and tube heat exchanger, in terms of better heat transfer and mass transfer coefficients After validating the methodology of CFD analysis of a heat exchanger against the numerical results available in literature, the effect of considering the actual fluid properties instead of a constant value is established. The characteristics of heat transfer inside a helical coil for different boundary conditions are compared. The flow field through the helically coiled tube is simulated by solving the appropriate governing equations: conservation of mass, momentum and energy. The turbulence is taken by Shear Stress Transport (SST) k-ε of closure.SST k-ε has a blending function which acts as a standard k-ε in main stream flow and as standard k-ε near the boundary layer where the gradient is much steeper. It is observed that the specification of a constant temperature or constant heat flux boundary condition for an actual heat exchanger does not yield proper modelling. Hence, conjugate heat transfer and temperature dependent properties of heat transport media are considered for the analysis of the heat exchanger. The CFD calculation results are obtained using the CFD package FLUENT 14.0.Since the above work necessitates the knowledge in CFD package FLUENT, a sample model of the helical coil heat exchanger is made using FLUENT before taking up the abovementioned project. The present report summarizes few of the studies thus made. The report also mentions the work performed with regard to the project problem Read More...

-K. Sri Sindhu ; Ms. C. Ada Christa; MR. C.L VIJAI KUMAR
In this thesis, the Angstrom-Prescott coefficients are determined by using Artificial Bee Colony algorithm and regression model in order to calculate the monthly average solar radiation for the particular region. In developing countries, the global solar radiation and its components are not available for all locations due to which there are a requirement of using different models for the estimation of global solar radiation that use climatological parameters of the locations. There are various empirical models are used to calculate the solar radiation but in this paper Angstrom-Prescott model is used to calculate the solar radiation of the particular region or area which provide the sunshine hours of that region. With the observation data of global solar radiation and sunshine-hours from one observation station, the Angstrom-Prescott formula is trained to determine all necessary parameters, by which the monthly average solar radiation data of the other weather stations with only sunshine-hour observation data can be derived. Several distribution maps of the global solar radiation are then generated using interpolation models in GIS, based on which spatial and temporal variation pattern of the monthly global solar radiation are discussed.

Sub synchronous Resonance Mitigation in DFIG-Based Wind Farm
-Pooja A. Patel ; Sweta Chauhan
Environmental pollution and shortage of conventional fossil fuel are the two major concerns which have led to the global emergence of wind energy as an effective means of power production. The increasing presence of wind power in power systems will likely drive the integration of large wind farms with electrical networks that are series-compensated to sustain large power flows. This may potentially lead to subsynchronous resonance (SSR) issues. In this paper, a supplementary controller on the grid-side converter (GSC) control loop is designed to mitigate SSR for wind power systems based on doubly fed induction generators (DFIGs) with back-to-back converters. This damping controller employs the rotor speed as the input signal. The validity and effectiveness of the proposed supplemental control are demonstrated on the IEEE first benchmark model for computer simulations of SSR by means of time domain simulation analysis using Matlab/Simulink.

OPTIMIZATION OF MICRO ELECTRICAL DISCHARGE MACHINING PARAMETERS OF Ti-6Al-4V
-RAJKUMAR P ; MURALIDHARAN S; NAGENDIRAN B; PARTHIPAN M; SIVANANTHAM K
Electrical Discharge Machining (µEDM) appears to be very promising as a future micromachining technique since in many areas of applications it offers several advantages. Brass (500µm) electrode is used as tool and Ti-6Al-4V is used as work piece. Different parameters, such as the Current, Pulse on time and Pulse off time are used to get the aperture’s size. Dielectric is De-ionized water. In µEDM setup, the dielectric flow circulating system is essential and must be considered carefully, otherwise the dirty dielectric will flow into the machining chamber again and cause second discharging of the work piece and infect the aperture’s sizes. Because the Brass electrode is too small, a use current passing will destroy the Brass electrode. Analysis indicates the most effective zone of predominant process parameters such as Current, Pulse on time and Pulse off time which give the appreciable amount of Material Removal Rate (MRR) with less Over Cut (OC). The experimental results and analysis on µEDM will open up more application possibilities for µEDM. This result shows the Current play an important part in the MEMS. Read More...

Document Reader Using An Android Platform
-Bhagyashri Jadhav ; Pratiksha Hundare; Tejashree Jadhav; Sonali Jagtap
Our purpose was to create an application that allows a user to jump to the correct section of an audio book by taking a picture of the page they are reading in a paper book. We used image processing algorithms such as the Hough transform to rotate pictures of the page, the Otsu’s method is used to threshold and binarize the image and brick wall coding (BWC) to detect features on the page. Then We will used a k-nearest-neighbour algorithm to assign a score to a test page by comparing it with pages in our database. We returned the closest matching page to the user generated picture. We obtained 40% accuracy over a dataset of 20 pages. In future work we could improve our accuracy by using angles between features which are more invariant to the pictures the user takes.

Multiple Imputation: An Alternative Solution for Filling Data
-Umamaheswari.D ; Vijay anand.R
Missing values, common in epidemiologic studies, are a major issue in obtaining valid estimates. Missing data are often a problem in social science data. Imputation methods fill in the missing responses and lead, under certain conditions, to valid inference. Simulation studies have suggested that multiple imputation is an attractive method for imputing missing values, but it is relatively complex and requires specialized software. This article reviews several imputation methods used in the social sciences and discusses advantages and disadvantages of these methods in practice. Simpler imputation methods as well as more advanced methods, such as fractional and multiple imputation, are discussed. The paper introduces the implementation in either multiple or fractional imputation approaches. Software packages for using imputation methods in practice are reviewed highlighting newer developments. The paper discusses an example from the social sciences in detail, applying several imputation methods to a missing earnings variable. The objective is to illustrate how to choose between methods in a real data example. A simulation study evaluates various imputation methods, including predictive mean matching, fractional and multiple imputation. This article reviews various imputation methods used within the social sciences to compensate for item-nonresponse bias, and provides the best result in using Multiple Imputation. Read More...

Analysis of The Heat Affected Zone in Co2 Laser Cutting of Stainless Steel
-Chaudhari Rajeshkumar Vihabhai ; M. D. Patel; J. B. Patel; H.C. Patel; A.G. Barad
This paper presents an investigation into the effect of the laser cutting parame-ters on the heat affected zone in CO2 laser cutting of AISI 304 stainless steel. The mathematical model for the heat affected zone was expressed as a function of the laser cutting parameters such as the laser power, cutting speed, assist gas pres-sure, and focus position using the artificial neural network. To obtain experimen-tal database for the artificial neural network training, laser cutting experiment was planned as per Taguchi’s L27 orthogonal array with three levels for each of the cutting parameter. Using the 27 experimental data sets, the artificial neural network was trained with gradient descent with momentum algorithm and the av-erage absolute percentage error was 2.33%. The testing accuracy was then veri-fied with 6 extra experimental data sets and the average predicting error was 6.46%. Statistically assessed as adequate, the artificial neural network model was then used to investigate the effect of the laser cutting parameters on the heat affected zone. To analyze the main and interaction effect of the laser cutting pa-rameters on the heat affected zone, 2-D and 3-D plots were generated. The anal-ysis revealed that the cutting speed had maximum influence on the heat affected zone followed by the laser power, focus position and assist gas pressure. Finally, using the Monte Carlo method the optimal laser cutting parameter values that minimize the heat affected zone were identified. Read More...

Analysis for The Accuracy of Thickness Measurement of Corrode Metal Plate by Ultrasonic Thickness Gauge
-Sheetal Kumar Dewangan ; Sandeep Kansari
This paper summarizes some of the major aspects of precision ultrasonic thickness gauging. Ultrasonic nondestructive testing (NDT) characterizing material thickness, integrity, or other physical properties by means of high-frequency sound waves has become a widely used technique for quality control. In thickness gauging, ultrasonic techniques permit quick and reliable measurement of thickness without requiring access to both sides of a part. During the thickness measurement of any corrode plate, the reading of ultrasonic equipment gives many different reading for each time of inspection at same position due to there non uniform surfaces. Any material whose thickness is lower than the low limit of the probe due to corrosion of metal piece will cause Measurement errors. Sometimes the displayed reading is twice as big as the actual thickness. To prevent these errors, the critical thin Materials should be measured repeatedly for verification. This paper looks at the root causes of poor performance with ultrasonic and suggests some methods to improve the situation. Read More...

An Electroless Plating - A Review Paper
-Yagnesh B. Chauhan
Electro less plating has become an established industrial technique and gained increasing importance at present. By such means not only pure metals but also alloys can be deposited on ferrous and non-ferrous materials to improve their surface characteristics. By using appropriate pee- plate treatment methods, a wide range of plastics and ceramics can also be plated by electro less methods. These processes have particular advantages in the field where galvanic processes can only be used at great expense or where they fail completely. Electro less nickel plating on steel is carried out by a chemical reaction and without the use of an external source of electricity. In electro less nickel plating, nickel chloride will come as a metallic salt and is reduced by using Sodium hypophosphite as the reducing agent to nickel metal, which then is deposited on the steel.
