Stress Analysis and Mass Optimization of Epicyclic Gearbox Housing A Review
-Bhavik S. Modi
The gearbox manufacturing Companies are proposing three to five stage epicyclic gearboxes and it is widely used in sugar mill and wind mill drives. It was found that high volume gearbox costs are very dependent upon material cost and the weights of the planetary drives. It was difficult to quickly find an optimum solution, while the space restriction was given and weight was to be minimized. For most of the gearboxes; housing dimensions are derived from thumb rule or empirical relations. Such process of design lead to conservative dimensions leading to bulky housing and such process was very time consuming. Today’s computational hardware and software offers quick analysis and design modifications capabilities which can be used for design improvement and optimization of products. So, here aims are stress analysis of the housing using ANSYS workbench and reduce the mass of the epicyclic gear train housing by using MATLAB optimization tool box. Read More...

image compression based on contourlet transform
-Himanshu M. Parmar ; Hitesh L.Desai
Image compression defines as reducing the amount of data required to represent digital image. Transform coding, on the other hand, first transforms the image from its spatial domain representation to a different type of representation using some well-known transform and then codes the transformed values (coefficients). There are mainly two Fourier based transformDCT and DWT are used for Image compression standards JPEG& JPEG2000 respectively.This two transform are not good enough for representing the geometric curve so need new techniques for image compression.This limitation is solving using the new technique called contourlet transform (CT). Which is based on Laplacian Pyramid and Directional Filter Banks (DFBs), can be capable of efficiently approximating natural images containing contours. Read More...

Distributed approach for Clock Synchronization Algorithm in WSN
-Ankur Chauhan ; Prof. Ramesh Prajapati; Dr.Samrat Khanna
Wireless sensor network has been a field where node’s clock synchronization has been a huge problem from decades to successfully transmit the data from source to destination there have been many research works about clock synchronization in Wireless sensor network in the literature and so many methods and protocols are proposed. Existing time synchronization algorithms provide on average good synchronization between a whole network, however, as we show in this paper, neighbour nodes in a network may be synchronized poorly. We propose the Distributed Clock Synchronization Algorithm (DCSA) which is designed to provide accurately synchronized clocks between nearest-neighbours. DCSA works in a completely decentralized fashion: Every node periodically broadcasts its time information. Synchronization messages received from direct neighbours are used to calibrate the logical clock. The algorithm requires neither a tree topology nor a reference node, which makes it robust against link and node failures. Read More...

A Novel Approach for Removing Metal Artifacts from Dental Images
-SHAH RIDDHIBEN D. ; GHANSHYAM D. PARMAR; J.B.VYAS
The artifacts that appear on maxillofacial X-ray computed tomography (CT) images are mainly caused by the presence of metallic prosthetic appliances such as amalgam or gold fillings. Artifact is one of the most important factors in degrading the CT image quality and plays an important role in diagnostic accuracy. The standard method used to reduce these metallic artifacts often consists of interpolating the missing projection data but the result is often a loss of image quality with additional artifacts in the whole image. Various methods based on the filtered back projection method, segmentation algorithm, and Restoration technique. The final corrected image is then obtained by merging the segmented metallic object image with the filtered back-projection reconstructed image from the image.
Proposed approach is based on CENTRIST method. Centrist is a form of non-parametric local transform used in image processing to map the intensity values of the pixels within a square window to a bit string. The centre pixel’s intensity value is replaced by the bit string composed of set of Boolean comparisons such that in a square window, moving left to right, If (CurrentPixelIntensityRead More...

PERFORMANCE ANALYSIS OF SMALL SIZE (BELOW 100CC) ENGINE WITH SUPERCHARGER USING GASOLINE ETHANOL BLEND
-RAHUL KUMAR SHARMA ; MANOJ KUMAR SHARMA; DARSHAN A KAPADIA; ASHISH JAIN
There are many inventions aimed at increasing the performance of IC engines. In general, practical engines are always compromised by trade-offs between different properties such as efficiency, weight, power, heat, response, exhaust emissions, or noise. When power increases efficiency is always decreases. Presently, ethanol is prospective material for use in automobiles as an alternative to petroleum based fuels. The main reason for advocating ethanol is that it can be manufactured from natural products or waste materials, compared with gasoline, which is produced from non-renewable natural resources.
Some methods and components are useful for increasing performance of engine. One such method is the use of supercharger in I.C. Engine. It is known that the power outputs of an engine increases with the increase in amount of air or mixture in the cylinder and supercharger plays an important role in increasing the amount or air. Till now supercharger is being successfully employed in heavy engines but its use with smaller engine is still under development. Thus this project employing a supercharger in small engine with capacity of nearly 100cc which used in two wheeler bike. In recent years, the motor vehicle industry aims at the small sized and high power density engine, while downsizing (small size and weight saving) and measuring the improvement in fuel consumption, and cleanization. Full power is needed only for accelerating and hill-climbing; during the remainder of the time the excess. Read More...

Efficiency Optimization & Detailed Energy Audit of a Textile industry
-Shivam R. Modi ; Prof. S.V.Damania
Energy conservation has now become a necessity. Considerable energy saving is possible through proper choice of equipments, and their effective use. The-only feasible way to handle energy crisis, apart from capacity addition, is the efficient use of available energy. For this there is a need of optimizing energy, using standard systems and procedures so as to reduce energy requirements per unit of output .In this paper a case study of industry for energy audit is presented. Energy audits don't save money and energy for companies unless the recommendations are implemented. Audit reports should be designed to encourage implementation, but often they impede it instead. The goal in writing an audit report should not be the report itself; rather, it should be to achieve implementation of the report recommendations and thus achieve increased energy efficiency and energy cost savings for the customer. Energy audit is an important tool in transforming the fortunes of any organization. This is highly relevant to the industry as it deals with a renewable energy source and looked upon as rural power house. The scope for conservation is immense and if properly harnessed can take the organization to the path of prosperity. Energy audit becomes all the more important in view of the energy conservation Act 2001 enacted by Government of India and the proposed New provisions.
The Result from the Energy audit of a textile industry located in Kim, surat. The Scope of Energy audit in a textile plant should include the study of Improve the Power factor of electrical utilities, replace the faulty capacitor, power saving by lighting management, install voltage stabilizer to reduce power consumption, improve Compressor & Pump efficiency and performance of Steam boiler. This paper consists the details of primary observations along with appropriate recommendation with supporting calculations. Certain areas are identified where there is a potential for saving in energy and measures have also been found for increasing plant productivity. Energy Conservation has been identified as a prime measure for cost reduction. Accordingly, the company has taken several in-house measures for energy savings and achieved substantial energy savings.

-Md. Obaid A. Khan ; Prof. S. V. Damania; Mr. M. Kumarvelu
This paper presents an approach for the optimization of air pre-heater design with inline & staggered tube arrangement. The tube failure of an air pre-heater in Gujarat Industries Power Company Limited (SLPP) is one of the main reasons for higher unit heat rate & is responsible for deterioration in boiler efficiency. The main problem of air pre-heater is the leakage of air to the flue gas side & thereby resulting in poor thermal performance. The higher ash content in Indian coal also adds to the problems associated with tubular air pre-heater.
Air pre-heaters are designed to meet performance requirements with consideration of highly influencing parameters viz. heat transfer, leakage and pressure drop. In the present work the performance of tubular air pre-heater is minimized tube failure by using different material of steel or by reducing H2SO4 formation from the flue gas while power plant taking start-up. In the flue gas system of a boiler plant, gaseous acidic substances (such as SOX and HCl) included in high-temperature exhaust gas condense into dew, depending on the moisture content of the gas and the surface temperature of a steel material to which it comes into contact, and corrode the material Read More...

MOTION DETECTION IN LOW RANK REPRESENTATION
-MIDHUN OMANAKUTTAN ; Mrs.Porkodi Prabhakaran M E,(Ph.D)
Object detection is a fundamental step for automated video analysis in many vision applications. Object detection in a video is usually performed by object detectors or background subtraction techniques. Often, an object detector requires manually labeled examples to train a binary classifier, while background subtraction needs a training sequence that contains no objects to build a background model. To automate the analysis, object detection without a separate training phase becomes a critical task. Several experiments have done using motion information. But existing motion-based methods are usually limited when coping with complex scenarios such as nonrigid motion and dynamic background. The project Motion Detection in Low Rank Representation addressed the above challenges in a unified framework named DEtecting Contiguous Outliers in the LOw-rank Representation (DECOLOR). This formulation integrates object detection and background learning into a single process of optimization, which can be solved by an alternating algorithm efficiently. Experiments on both simulated data and real sequences demonstrate that DECOLOR outperforms the state-of-the-art approaches and it can work effectively on a wide range of complex scenarios.

Design and development of aqua silencer for two stroke petrol engine
-Kevalkumar Ishwarbhai Patel
Air pollution is most important from the public health of view, because every individual person breaths approximately 22000 times a day, inhaling about 15 to 22 kg of air daily. Polluted air causes physical ill effect decides undesirable aestheticand physiological effects. Air pollution can be defined as addition to our atmosphere of any material, which will have a dexterous effect on life upon our planet. The main pollutants contribute by automobile are carbon monoxide (CO), unburned hydrocarbon (UBHC), oxides of nitrogen (NOx) and Lead. Automobiles are not the only sources of air pollution, other sources such as electric power generating stations, industrial and domestic fuel consumption, refuse burning, industrial processing etc. also contribute heavily to contamination of our environment so it is imperative that serious attempts should be made to conserve of our environment from degradation. An Aqua Silencer is an attempt, in this direction, it is mainly dealing with control of emission and noise. An Aqua Silencer is fitted to the exhaust pipe of engine. Sound produced under water is less hearable than it produced in atmosphere. This mainly because of small sprockets in water molecules, which lowers its amplitude thus, lowers the sound level. Because of this property water is used in this silencer and hence its name AQUA SILENCER. The noise and smoke level is considerable less then the conventional silencer, it is cheaper, no need of catalytic converter and easy to install. Read More...

DIGITAL BEAMFORMING IN SYNTHETIC APERTURE RADAR
-Abhishek Ashokbhai Rathod ; Prof.Manish.P.Patel
Various Algorithm techniques is proposed for beam forming of space borne Synthetic Aperture Radar (SAR), which is equipped with active phased array antenna (APAA). The basic idea of the approach is that the phase and amplitude distributions of the element excitations can be represented by a few basis functions, as any functions can be expressed by a set of the complete orthogonal basis functions. Furthermore, by optimizing the weights of basis functions, the beam shaping and side lobe notch can be achieved. In this algorithm, Legendre Polynomials (LP’s), sine and cosine are utilized to define phase and amplitude distribution, respectively.
Considering the difference between the transmitting and the receiving channels of T/R module, phase-only synthesis with uniform amplitude and complex excitation control are applied in the transmitting mode and the receiving mode, respectively. Based on the proposed algorithm, we achieved great reduction in the number of variables, obtained smoother curves of the phase and amplitude distributions and accelerated the convergence process, in comparison with conventional GA and PSO. Finally, numerical simulation results are presented to verify the effectiveness of the particular algorithm. Read More...

Implementation of QAM Modulator on FPGA with ADC/DAC
-Bhavsar Devang Kamleshkumar
The development in the modulation techniques
had been witnessed since last two decades which demands
reliable transmission of information with higher data rate.
Modulation scheme such as QAM (Quadrature Amplitude
Modulation) is one of the widely used modulation
techniques in cellular communication because of its high
efficiency in power and bandwidth. 16-QAM is a kind of
digital modulation scheme which transmits four bits per
symbol on two orthogonal carriers; one in phase and the
other one is in quadrature phase. Hence the data rate is
increased by a factor of four. It is quite preferable as there is
a balance between obtaining the higher data rates and
maintaining an acceptable bit error rate keeping the
energy of the constellation constant. Development of
MATLAB model of 16 QAM MODEM and its simulation is
done. High speed ADC/DAC card FMC150 interfaced with
Xilinx FPGA Virtex-6. VHDL code for 16 QAM
Modulator was developed and ported on Xilinx FPGA

EXPERIMENTAL INVESTIGATION OF HYDROGEN PORT FUEL AS A PART OF SUPPLIMENT ON 4-STROKE SI ENGINE
-PRANAY N. PATEL ; HITESH K. SOLANKI
In this study, Hydroxy gas (HHO) was produced by the electrolysis process of different electrolytes (KOH(aq), NaOH(aq), NaCl(aq)) with various electrode designs in a leak proof plexiglass reactor (hydrogen generator). Hydroxy gas was used as a supplementary fuel in a four cylinder, four stroke, spark ignition (SI) engine without any modification and without need for storage tanks. Its effects on exhaust emissions and engine performance characteristics were investigated. Experiments showed that constant HHO flow rate at low engine speeds (under the critical speed of 2800 rpm for this experimental study), turned advantages of HHO system into disadvantages for engine torque, carbon monoxide (CO), hydrocarbon (HC) emissions and specific fuel consumption (SFC). Investigations demonstrated that HHO flow rate had to be diminished in relation to engine speed below 2800 rpm due to the long opening time of intake manifolds at low speeds. This caused excessive volume occupation of hydroxy in cylinders which prevented correct air to be taken into the combustion chambers and consequently, decreased volumetric efficiency was inevitable. Decreased volumetric efficiency influenced combustion efficiency which had negative effects on engine torque and exhaust emissions. Therefore, a hydroxy electronic control unit (HECU) was designed and manufactured to decrease HHO flow rate by decreasing voltage and current automatically by programming the data logger to compensate disadvantages of HHO gas on SFC, engine torque and exhaust emissions under engine speed of 2800 rpm. The flow rate of HHO gas was measured by using various amounts of KOH, NaOH, NaC1 (catalysts). These catalysts were added into the water to diminish hydrogen and oxygen bonds and NaOH was specified as the most appropriate catalyst. It
was observed that if the molality of NaOH in solution exceeded 1% by mass, electrical current supplied from the battery increased dramatically due to the too much reduction of electrical resistance. HHO system addition to the engine without any modification resulted in increasing engine torque output by an average of 19.1%, reducing CO emissions by an average of 13.5%, HC emissions by an average of 5% and SFC by an average of 14%.

-Ravi D. Patel ; Jay Vala; kanu patel
In Data Mining, Association rule mining and classification are most important tasks for decision making process based on data. Single-Label classification only Predict the single class label but nowadays most of the Application require more than one class label for Prediction eg. Music and text categorization, Medical diagnosis. Above Issue can be solved by Multi-label classification But the disadvantage of that is in this technique due to more number of label number of rules generated by the algorithm is too large and redundant. So discovery of strong rules is more harder this problem can be solved by the ranking and Pruning method using Parameter like Entropy and Information Gain. Still not giving good result so future work is we can apply pruning using the factors like Confidence and database Coverage. In this paper some of the techniques for rule ranking and pruning are explained for associative classification. Read More...

STRESS ANALYSIS OF HALF TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION SYSTEM
-CHINTAN RAMESHCHANDRA PATEL ; Dr. H. S. PATIL; Mr. JUBIL JOY
The continuously variable transmission, or CVT, continues to emerge as a key technology for improving the fuel efficiency of automobiles with internal combustion (IC) engines. A toroidal continuously variable transmission (CVT) has an elliptical shape in the contact area, which resulting high contact stress and transmits the power. Many parameters affect the contact stress of the half toroidal CVT, which include the properties of the contacting material (Young’s modulus), operating parameter (input load) and geometrical parameters (aspect cavity ratio, curvature ratio and half cone angle of the power roller, transmission ratio). In this paper, the contact between the input disk and the power roller are formulated using the classical Hertzian contact theory. Based on the formulated equations, different system parameters, which affect the maximum Hertzian contact stresses, are compared with the simulated results generated in ANSYS. The comparative results will provide some observations of the relations between the maximum Hertzian stresses and input load in the form of graphs for different materials (i.e. 100Cr6/Si3Ni4, 100Cr6/Ni75%, Cr 14%, Fe 10%, 100Cr6/100Cr6, 100Cr6/Ni70 %, Cu 30 %). These graphs give useful information for designer to know the maximum Hertzian stress during operation in such systems. Read More...

Enhancement of Material Removal Rate in EDM
-Solanki Chetankumar ; V.S.Bali
Electrical Discharge Machining (EDM) is one of the earliest non-traditional machining process. EDM process is based on thermoelectric energy between the workpiece and electrode. Material removal rate (MRR) is an important performance measure in EDM process as it is very slow then other traditional machining processes. Since long many EDM research have been explored a number of ways to improve and optimize the MRR including some unique experimental concepts. Despite a range of different approaches , all the research work in this area shares the same objective of achieving more efficient material removal coupled with a reduction in tool wear and improved surface quality. The paper reports research on EDM relating to improvement in MRR along with some insight into mechanism of material removal. In this research attention is focussed on the analysis of MRR by increasing the amount of heat content externally using some explosives like Carbon and Sulphur. DOE approach is adopted to justify the exact response of the Heat Input(Q) with two other parameters like Current(Ip) and Air-Pressure (Pa) as Input parameters. MRR is taken as a response parameter. The Experiment is done by L9 array and result are calculated and analysed to know the effect of parameters. Read More...

FRICTION BETWEEN PISTON RING AND LINER IN I.C. ENGINE
-MODI JENISHKUMAR P ; D.C. GOSAI; Dr. K. N. MISTRY
In IC engine piston ring friction losses account for approximately 20% of total mechanical losses as reported in the literature. A reduction in piston ring friction would therefore result in higher efficiency, lower fuel consumption and reduced emissions. To reduce these losses, various parametric approaches are made particularly at design stage and experimental level. The goal of this study was develop lubricants to improve engine efficiency, without adversely affecting oil consumption, blow by, wear and cost. The variable parameters are piston velocity, engine speed, oil viscosity, gas pressure, crank angle film thickness and coefficient of friction. Non variable parameter are system constant, bore diameter, ring tension, ring width, compression ratio, reciprocating mass, piston ring area and piston ring profile. The major assumptions for developing models are either hydrodynamic lubrication theory of Reynolds equation or boundary lubrication theory. Paper shows the effect of different lubricants i.e. SAE 2T, SAE 4T, SAE 20W40 on friction force acting between the piston rings and cylinder liner of IC engine Read More...
