ACCURATE CLASSIFICATION OF COLOR IMAGE BASED ON HISTOGRAM FEATURES

 

IJAERS/Vol. III/Issue II/January-March, 2014/07-09

  Authors:Mahendra S. Sawane, Prof. Amit R. Sarkar
 

ABSTRACT
First we are going to prepare dataset of training images. After this we are creating training dataset which contains color histogram features extracted from training images. As we are going to make classification of a color image for that we have to decide the number of classes to which we have to classify the test image. In training matrix according to this we are going to give the true labels. Then we take a test image first we do preprocessing to remove noises from them. Features are extracted from the denoised images. In this paper we extract the color histogram features from the color image. The features are extracted from the test image. The extracted features of the test image and the training images are then passed into the classifier. The classifier analyze the feature values and match them with the true label and finally produce the classification result. We propose a novel approach for content based color image classification using Support Vector Machine (SVM). Color image classification is done on features extracted from histograms of color components. The benefit of using color image histograms are better efficiency, and insensitivity to small changes in camera view-point i.e. translation and rotation.

IJAERS/Vol. III/Issue II/January-March, 2014/18-19

  Authors:Swapnil Ravindra Ranage, Dr. L.Y. Waghmode, Swapnil S. Kulkarni
 

ABSTRACT
The high pressure or fluid tight applications call for added strength of the pipes carrying the fluid from the source to the point of use. Composite materials offer a promise for developing solution to such applications. The layered orientation of each material alongwith a binder can enhance the strength of the pipe. The FEA method can predict the behavior of the material subjected to deformation or its capacity to withstand the stresses encountered. Suitable FEA software like Nastran would be employed for finding the suitability of the given composition of the material for the intended application. The physical experimentation and validation would be done at the sponsoring Company/ Test Lab over a standard prototype.

  Authors:*S.S. Shirguppikar, V.S.Ganachari, P.S. Dhaingade, A.D. Apte
 

ABSTRACT
In order to achieve reliable welds with minimum distortion for the fabrication of components for the aerospace industry. Several techniques were explored using the CO, and the Nd:YAG pulsed laser. In the tests it was established that a satisfactory weld can be obtained using the CW laser. Of these techniques, laser welding can provide a significant benefit for the welding of titanium alloys because of its precision and rapid processing capability. For pulse mode Nd:YAG laser welding, pulse shape, energy, duration, repetition rate and peak power are the most important parameters that influence directly the quality of pulsed seam welds. In this study, experimental work involved examination of the welding parameters for joining a 3-mm thick titanium alloy using the Lumonics JK760TR Nd:YAG pulsed laser. It has been determined that the ratio between the pulse energy and pulse duration is the most important parameter in defining the penetration depth.

 

PERFORMANCE CHARACTERISTICS OF DI -CI ENGINE USING PONGAMIA BIODIESEL – DIESEL BLEND AS FUEL

 

IJAERS/Vol. III/Issue II/January-March, 2014/23-27

  Authors:S.V. Kale
 

ABSTRACT
The conventional petroleum fuels for internal combustion engines will be available for few years only, due to tremendous increase in the vehicular population. Moreover, these fuels cause serious environmental problems by emitting harmful gases into the atmosphere at higher rates. Generally, pollutants released by engines are CO, Unburnt hydrocarbons, NOx, smoke and limited amount of particulate matter. At present, alternative fuels like methyl esters of vegetable oil (commonly known as biodiesels), alcohols etc. are in the line to replace the petroleum fuels for IC engines. In the present study an experimental investigation was carried out with pongamia oil as an alternative fuel in a compression ignition engine. The problems associated with vegetable oil are high viscosity, low volatility and high reactivity, but at the same time their higher cetane number, lower sulphur content and higher oxygen concentration are the desirable properties to use as a fuel in compression ignition engines. The process of transesterification of vegetable oil with methyl alcohol provides a significant reduction in viscosity, thereby enhancing the physical properties of vegetable oil. The current paper reports a study carried out to investigate the combustion, performance and emission characteristics of Pongamia oil methyl ester with diesel fuel on a single-cylinder, four-stroke, direct injection and water cooled diesel engine. This study gives the comparative measures of brake specific fuel consumption, brake specific energy consumption, brake thermal efficiency, mechanical efficiency, exhaust gas temperature, air-fuel ratio, volumetric efficiency, CO, CO2, HC, NOx and smoke opacity,. Biodiesel can be blended at any ratio with diesel fuel. The properties of Pongamia biodiesel are determined, and found that its properties are near to diesel.

 

IMPLEMENATATION OF MATLAB-SIMULINK APPROACH IN SHUNT ACTIVE POWER FILTERS TO MINIMIZE THE HARMONICS

 

IJAERS/Vol. III/Issue II/January-March, 2014/28-35

  Authors:Sanyog Dubey, Anand Singh
 

ABSTRACT
Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. This paper presents the analysis and simulation using Matlab Simulink of a three-phase four wire neutral clamped active power filter (APF) compensating the harmonics and reactive power created by nonlinear balanced and unbalanced low power loads in steady state and in transients. The usefulness of the simulation approach to APF is demonstrated so APF designers have a better insight using Matlab Simulink in order to develop new APFs.

ABSTRACT
Runoff is a complex interaction between precipitation and landscape factors. While some of these factors (e.g., land use and cover, topography, soil characteristics, and hydrologic condition) have been defined for urban, rangeland, and agricultural drainages, runoff from mountainous, forested watersheds is poorly understood. This study investigated the response of stream flow to rainfall on gauged, small watersheds of the Morbe project using method to estimate runoff; the semi-empirical curve number method. Alternative techniques for calibrating watershed curve numbers were first assessed to determine whether these methods provide acceptable estimates. Runoff estimated using tabulated curve numbers was assessed separately. Curve numbers calibrated using rainfall-runoff observations provided adequate estimates for watersheds. Even calibrated curve numbers contain large uncertainties, thus requiring statistical proof that estimated runoff adequately agrees with observations for use in critical designs. For ungagged, forested watersheds, estimated curve numbers should be independently confirmed using data from gauged watersheds with similar hydrologic conditions. The effects of seasonal variation on curve numbers were evaluated. Design engineers and analysts should consider this seasonal variation to adjust curve numbers; otherwise, runoff calculations are even poorer estimates.

ABSTRACT
The Universal Soil Loss Equation (USLE) parameters were assessed using Satellite Remote Sensing (RS) and GIS with a view to model soil erosion in Sallar Wullarhama Watershed State of Jammu and Kashmir. The average rainfall erositivity factor (R) for Sallar Wullarhama Watershed was calculated by using equation for the determination of R-value. Each grid cells of mean annual rainfall were calculated based on this equation to get the R-value using GIS software, Arc GIS 9. The soil erodibility factor (K) for the present watershed is computed by using the relationship between soil texture class and organic matter content. The soil erodibility factor (K) values in the watershed ranges from 0.19 - 0.42, based on the soil texture class. For the present study the (LS) factors were calculated after the generation of Digital Elevation Model (DEM) for the study area from the topographical sheet. The contour data were extracted from the SOI toposheet (1:50,000) of the study area. The LS values of the study area ranges in between 0.5 - 5.5. As the slope values increase SL value decreases. The land use and land cover map of the study area was used for analyzing the C-value. The c-value of the study area ranges from 0.024 to 0.58. On the basis of C value estimation, same grid method was used for estimation of P value in the study area. P factor values have been assigned on the basis of relation between terracing and slope, contouring and slope in the different land facets and crop field area in the study area. The P factor was assigned using values. The P values ranges from 0.69-0.97. Average annual soil loss were calculated by multiplying five factors: R; the erosivity factor, K; the soil erodibility factor; LS, the topographic factor; C, the crop management factor and P; the conservation support practice. The average soil loss predictions range between 0.075565- 59.328 kg/m2 /yr. Sub-basin wise soil loss was calculated the study area was categorized into 6 sub-basins (SW1-SW6) and it was found that highest soil loss was found in SW1 and SW3 respectively. These watersheds show inherent characteristics of high proportion of wastelands.

ABSTRACT
It is becoming increasingly important to accurately predict the behavior of bolted joints. This research work would be focused particularly on the stress concentration that develops at the root of the loaded threads, when the bolts are loaded statically with uniaxial external loads. Historically, the value of the bolt as a fastener is very great. Bolted joints have been used in a wide range of engineering structures for hundreds of years. Bolted joints are widely used in industries e.g. pressure vessels, automobiles, machine tools, home appliances and so on. It is also likely that bolted connections will continue to grow in usefulness in the future. Bolted joints are most commonly used components in machines and structures. The fasteners generally represent the largest single cause of the warranty claims faced by the automobile manufacturers [12] often potential durability problems in the machine or structures are proportional to the number of bolted joints used.

ABSTRACT
Depletion of nonrenewable source of energy (fossil fuels like petroleum, coal and natural gas) many researchers are looking forward to find an alternative source of renewable energy. One such alternative to diesel fuel is biodiesel. Biodiesel can be defined as fuel comprising of mono alkyl ester of long chain of fatty acid derived from vegetable oil or animal fat.
So, there is an increasing interest in India to search for suitable alternative fuels that are environmental friendly. Environmental concerns and limited amount of petroleum resources have caused interests in the development of alternative fuels for internal combustion (I.C.) engines. As an alternative, biodegradable, renewable and sulphur free biodiesel is receiving increasing attention. The use of biodiesel is rapidly expanding around the world, making it imperative to fully understand the impacts of biodiesel on the diesel engine combustion process and pollutant formation. Therefore, in this study, the performance test of a variable compression diesel engine with neat diesel fuel and biodiesel mixtures was carried out.
Experiments are carried out by using dual biodiesel blends and compared it with diesel fuel characteristics. The literatures were focused on single biodiesel and its blends. So far a very few dual biodiesel blends of oils have been tried on diesel engine leaving a lot of scope in this area. This paper investigated the performance and emission characteristics of various dual biodiesel blends (mixture of biodiesel and diesel fuel) of Thumba biodiesel on a single cylinder variable compression ratio diesel engine having bore diameter 87.50mm, developed power 3.5kw at 1500rpm, compression ratios 12 to 18, stroke length 110mm, water cooled engine. The biodiesel blends of B10% (combination of Diesel 90% by volume, biodiesel 10% by volume ) and B20% (combination of Diesel 80% by volume, biodiesel 20% by volume) gave better brake thermal efficiency and lower brake specific fuel consumption than other biodiesel blends. The blends of B10% and B20% have superior emission characteristics than other blends and closer to diesel values. From the experimental results obtained, Thumba oil blends are found to be a promising alternative fuel for compression ignition engines. At CR 18 BTE and BSFC of Thumba B10, B20 and BP of Thumba B40 showed better performance.CO, HC, CO2 of B100 of Thumba biodiesel showed less emission percentage/ppm, for NOx emission B10 and B20 of Thumba, biodiesel showed less emission ppm.

IJAERS/Vol. III/Issue II/January-March, 2014/81-83

  Authors:Rajkumar Ashok Patil Tekale, Prof. D.D.Date, Swapnil S. Kulkarni
 

ABSTRACT
The engine of any automobile runs at high speed, typically, about 1000rpm for idling and increases further during the ride. Every stroke of the engine subjects its adjacent components to cyclic loading that pulls and pushes the components like piston, connecting rod and crankshaft. The crankshaft, in turn, is connected to the transmission system and is a critical component from the design perspective. The design of the component can be done in a justifiable manner if an attempt is made to identify the effects of the operating loads on the component in the form of the type of stress induced with its peak value and the location of these stresses over the component. For this sake, Finite Element Analysis is sought to be employed over this dissertation work. Alternatives for Design and/or material would be suggested while attempting to modify the geometry of the Crankshaft. Suitable software for `fatigue analysis’ (example – MSC Fatigue) would be deployed for solving the problem using FEA techniques.

IJAERS/Vol. III/Issue II/January-March, 2014/84-88

  Authors: Perugu Venkata Narayana, N. Venkata Ramana
 

ABSTRACT
This thesis first outlines the theory, historical background, and application of obtaining the joint variables that result in a desired position of the robot end-effectors’ called as inverse kinematics. Find the inverse kinematics is one of the most important problems in robot kinematics and control. As the complexity of robot increases, obtaining the Inverse kinematics solution requires the solution of non linear equations having transcendental functions are difficult and computationally expensive.
In this paper, using the ability of Adaptive Neuro-Fuzzy Inference System (ANFIS) to learn from training data, it is possible to create prediction of Inverse Kinematics of 6- degree of freedom (DOF) manipulator in this work. After comparing the output, it is concluded that the predicting ability of Adaptive Neuro-Fuzzy Inference System (ANFIS) is excellent as this approach provides a general frame work for combination of Neural Network and fuzzy logic. The Efficiency of ANFIS can be concluded by observing the surface plot, residual plot and normal probability plot. This current study in using different nonlinear models for the prediction of the Inverse kinematics of 6-degree of freedom robot manipulator will give a valuable source of information for other models.

SEGMENTATION OF HUMAN PALM FOR SYMBOL DETECTION AND PATTERN MATCHING

 

IJAERS/Vol. III/Issue II/January-March, 2014/97-101

  Authors: Dr. Hardik B. Pandit and Prof. Dipti Shah
 

ABSTRACT
This paper is focused on development and implementation of an algorithm to segment the human palm into several meaningful regions. Segmentation of the palm is needed for automatic symbol detection, pattern matching, and object identification by the computer. Highlighting feature of the algorithm is that, it does not include human intervention throughout the process. The fields like criminology, fingerprint recognition, security, medical science, and palmistry need careful study of different sections of palm. Now days, all these fields are computerized, but still there are some steps where human intervention is needed. The developed algorithm removes the role of human in all above mentioned processes.

ABSTRACT
This report is about the design of steam piping and its stress analysis of a given process flow diagram. The prime objective of this project is to design the piping system and then to analyze its main components. Wall thicknesses are calculated for all pipes which were found very safe for the operating pressure. For header pipe the calculated wall thickness is 3.54 mm and the standard minimum wall thickness is 8.18 mm which is greater than the calculated one by more than 2.3 times. Different loads such as static loads, occasional loads and thermal loads of all pipes were also calculated. After load calculations, spacing of supports and designing of expansion loops were carried out. Thermal, static and seismic analysis of main system pipe has been done and results were compared with ASME Power Piping Code B31.1. After calculation of all applied loads, pipe components were designed and analyzed both manually and on ANSYS software. The results obtained from both methods were compared and found safe under available applied loads. Considering the mathematical model for the piping design, the calculations might suggest an under-designed system vis-à-vis the relevant CODE. Though, a certain standard exists for a given application, there is enough room to explore the optimization of design since the projects associated with piping are normally associated with a high quantum of purchase running in several million rupees to a few billion! Any attempt to rationalize the design would directly improve the savings for the budgetary outlay for the project work while ensuring safety and addressing concerns for potential claims arising due to accidents or malfunction of the system.

  Authors:Mohit Poonia, Ram Avtar Jaswal
 

ABSTRACT
At present time, Electric energy is more usable form of energy in all types of energy forms because it is directly affect the life of any person in the world. The electric energy has three main stages i.e., Generation, Transmission and Distribution. Here transmission line is used to transmit the electric energy from generating source to Distributing end. The demand of energy is increasing day by day. So, to maintain the demand and supply the system must be updated. System became complex because of increasing load conditions. We update the system according to the expected load condition of present and future. For update/change of system we can use Transmission Expansion Planning Techniques. By using Transmission Expansion Planning we can maintain both demand and supply and also efficiency are high and losses are less. In this Paper various plans are proposed for Transmission expansion planning.

ABSTRACT
Injection molding is a process of forming an article by forcing molten plastic material under pressure into a mould where it is cooled, solidified and subsequently released by opening the two halves of the mould. Determining optimal initial process parameter settings critically influences productivity, quality, and costs of production in the plastic injection molding (PIM) industry. The plastic injection moulding cycle consists of four phases: plastication, injection, packing, and cooling. Therefore, several process parameters which include the melt temperature, mould temperature, injection pressure, injection velocity, injection time, packing pressure, packing time, cooling temperature, and cooling time all potentially influence the quality of injection-moulded plastic products. Incorrect input parameters settings will cause bad quality of surface roughness, decreases dimensional precision, Warpage, unacceptable wastes, increases lead time and cost. Therefore, finding the optimized parameters is highly desirable. In past scientists used trials and error to find good process conditions but this method is time and cost consuming. In addition, when there are a large number of input parameters, these methods can’t be used. Nowadays, the model of the process and optimal condition are developed using analytic methods and heuristic algorithms.
The method for finding the optimized solution would involve use of Flow analysis software like Mould-Flow. The use of this software would highlight the recommended values of the parameters for Injection Moulding for the specified component design. Defect prevention coupled with minimum cycle time results in optimization of the process. A realtime analysis of the flow helps to identify the problem areas and depicts the results while the parameters are manipulated for effecting better results.

ABSTRACT
Designing the handle bar assembly of a two wheeler poses many challenges including assessment of the structural strength of the mating components. While the handle bar is subjected to buckling (pre-dominantly) the housing and the other frame experiences tensile, compressive and shear stress. The conditions during braking and the forces extended due to road bumps and pot holes can exaggerate the problem. This work shall focus on conducting linear constructural analysis while evaluating and rationalizing the loads.

ABSTRACT
In this paper a model has been presented for computation of minimum explosible concentration of organic dust- air mixtures to examine the probability of explosion in a stated dust-air environment and design adequate explosion preventive measures. The model is based on the assumption that the devolatilzation/ decomposition step is very fast and combustion controls dust explosion. The modelling predictions are compared with experimental data for organic dusts- maize starch and coal to verify the validity of model, and close agreement between them indicated that the model represents experimental measurements very well. The data from experiments to study the influence of temperature, particle size and residence time on the products formation and composition of gases during pyrolysis of organic dusts using modified Godbert-Greenwald furnace have been used in model predictions.

ABSTRACT
Heat dissipation is one of the most critical considerations in engine design and with an efficient cooling system; performance of the engine can be dramatically improved. All internal combustion engines convert chemical energy into mechanical power. Around 70% of the energy is converted into heat and therefore, the primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air. A radiator transfers heat from the hot coolant to the air and an effective design of radiator will ultimately lead to enhanced engine performance by reducing the heating effect.

ABSTRACT
"The marginal increment in the discharge for the Centrifugal Pump tends to depreciate with each marginal rise in capacity of the pump; especially for the higher order pumps (25HP and above). The prominence of vortices alongwith turbulent flow at the regions in the suction pipe affects the flow of water and consequently the discharge. The discharge could further drop if the `sump' is not favorably designed for aiding the intake through the suction pipe. This work would focus on Design alternatives for minimizing the vortices within the suction pipe and enhancing the discharge through possible use of a manifold at the suction end. Alternatively, efforts would be pursued for addressing the Design of the Sump (Tank) for facilitating the flow of water at the suction end while smoothing out the in-rush of water at the extreme end of the suction pipe."

ABSTRACT
Vibratory bowl feeders are the most versatile common feeding and orientating devices for automatic assembly widely used in many industry fields. The feeders are actuated by electromagnets, while rubber mounts are positioned under the base for reducing the vibration transmission to the floor. The model has been experimentally verified by means of modal analysis. The proposed model has been activated by electromagnet and its modal characteristics were analyzed through both the finite element method and experiment, for the analysis of feeder dynamics and for evaluating the effects of changes in design and operational parameters in terms of bowl and base vibration and dynamic forces transmitted to the floor.

ABSTRACT
The power sector is contributing more to the global warming potential. Renewable energy technology is one of the alternative to reduce the carbon emission and global warming potential. In the renewable energy, wind and solar cell power are the best methods to produce the power. But the efficiency of the systems are fairly low compared to the conventional method. This paper presents the most important factors that affect the power output of the wind and solar cell system. The efficiency of the system mostly depends on the climate condition of the particular location. This paper discusses about the effect of temperature and irradiation on the solar cell power output. Also a mathematical model is developed to study the parameters that affect the electrical power generated by the wind turbines. The considered parameters are turbine swept area, air density and wind speed. They are tested for the V1.65MW and V1.8MW wind turbines and also for the 124W and 170W solar panel. In this paper, the location has been taken as Gandhigram Rural University, Dindigul, Tamil nadu, India.

ABSTRACT
In this paper, energy saving in Mud house as compared to brick wall building is discussed by selecting a proper insulation material and different wall materials. Buildings made of mud bricks act as environmental friendly. The thermal insulation keeps the indoor temperature constant during summer and winter seasons. The mud house aims to save energy by providing a more stable temperature and reduces heat losses. Mud is a thermal mass that absorbs sun light and warms the building over the course of the day. The various parameters which are considered in the paper are orientation of walls, building exposed to sun, surface-volume ratio, wall materials, ventilation and shading. Sustainable construction is achieved using natural resources, such as mud to conserve the energy both during construction as well as for achieving thermal comfort inside the house. The effect of heating and cooling loads on energy consumption is determined. The annual heating and cooling load requirement can be obtained by Degree- Days (DD) method. Expended Polystyrene (EPS) and Rockwool (RW) are selected as insulation materials. In this paper the optimum insulation thickness for mud house and brick wall house was calculated. The calculation was carried out for four different energy sources i.e. coal, LPG, Natural Gas and Fuel Oil. This paper contributes to the promotion of mud house (passive) and low energy architecture towards a sustainable future.
Results show that optimum insulation thickness varies between 0.578 cm to 6.18 cm , the energy saving per sq. meter varies between Rs. 28 to 1479 and payback periods varies between 2.196 to 6.99 years depending on type of building wall, insulation material, climatic condition and fuel cost

ABSTRACT
While molding is a `process’ that would need study from this point of view, the physical Mold would need orientation from the Designer’s perspective. The type of Mold to be designed, the dimensions/ specs for each of the element in the Mold, the location of the gate, etc are considerations that a Design Engineer could offer more convincingly. The effort of this thesis work is to identify the nuances in the Design of the Plastic Injection Mold while borrowing the inputs from the `Flow Analysis’ conducted for the component to study the behavior of the Melt during processing. The Mold Design would incorporate suitable checks for ensuring the best quality product in terms of `defect-free’ output.

ABSTRACT
In this paper, solar drying technologies for drying fruits, vegetables, spices, cereals, grains, legumes, medicinal plants and fish for global food security are reviewed. The review identified that drying methods affect sensory characters and nutritive attributes of dried products. For nutrient preservation of dried products and superior drying speed, the indirect forced convection type solar dryers are preferred but power requirement increase the cost of drying as well as limit their use in the rural areas. Natural-circulation type solar tunnel dryers, wind ventilated type solar dryers with heat storage units and greenhouse dryers are more suitable for rural applications. The use of solar collector’s performance enhancement techniques accelerates drying rates and promotes overall efficiency of drying systems. Solar-biomass hybrid dryers overcome the limitations of solar drying during cloudy conditions and night hours. The review suggested that computer simulated models should be adapted as a tool in the design and optimization of solar dryers for short and long time benefits while low initial capital cost, operational procedure and effectiveness in promoting better product quality should be consider in the design and production of solar drying systems.

ABSTRACT
In the present study, the wind energy potential evaluation of some selected towns in the North East of Nigeria were statistically analyzed based on Weibull and Rayleigh Models using sixteen (16) years mean monthly wind speed data covering the period of 1997-2012. The result shows that Rayleigh is the best fit model that describes the wind speed data at 10m height above the sea level. However, Weibull model was found to present the actual probability of the wind speed data for all the locations as a comprehensive study for wind power. Hence, the Weibull model is recommended for the region .The study also shows that North-East Nigeria has potential for energy generation with highest power density of 59.96W/m2 found to be in Maiduguri, Borno state.
