    DESIGN AND DEVELOPMENT OF AN AUTOMATIC HEAD LAMP LEVELING SYSTEMS FOR AUTOMOBILES

    By K. Ranjithkumar1, P. Ganeshan1, P. Raju, B. Prabu2, V. Mohanavel3, S. Dinesha1, S. Hariharan1, S. Jayasuriya1, G. Amarnath1

    Abstract

    A head lamp is usually attached to the front of a vehicle such as a car, with the purpose of illuminating the road ahead during periods of low visibility, such as night or precipitation. Headlight to be used in informal discussion interchangeably, headlamp is the correct technical term for the day to-day device itself, while headlight properly refers to the beam of light produced and distributed by the device. A headlamp can also be mounted on a bicycle with a battery or small electrical generator, and most other vehicles from trains to airplanes tend to have their own headlamps. A head lamp auto-leveling system can be used inexpensively and for a long term by reducing the unpleasant feeling in the driver. An implementation of the head-lamp leveling system includes head lamps whose axis is tilted horizontally/vertically with respect to a vehicle turning movement


    SYNCHRONIZER LIFE ENHANCEMENT USING CARBON FIBRE COMPOSITES

    By K. Chandramohan, P. V. Arunraj, A. Haymik Raja,

    Abstract

    The synchronizer in a domestic tractor is observed to be having a lifetime of 2-3 efficient years with the current material used for synchronizer being Brass. In this work with discuss about how to enhance the existence time of synchronizer by replacing Brass with Carbon – Carbon composite (C-C) material. The pattern of the carbon fiber chosen is Woven Roving Mat (WRM) which is blended with Epoxy resin with two layers of 0.5 mm thickness as a laminate. The WRM cloth is rolled over by the Epoxy resin with the help of a roller and then both are kept inside the bottom portion of the die arrangement. As design has the central guiding, the die can be inserted easily and straight into the bottom portion and the top portion is pressed inside the bottom portion. The composite friction material die is designed with AISI H13 steel and manufactured. A pressure of 400 kg/cm2 is applied to an area of 7.02 cm2; therefore, a force of 2800 kg is required, hence a 5 Ton hydraulic press is used. The result is observed that the carbon – carbon composite shows enhanced strength and endurance properties than the brass. By the results obtained we infer that brass can be replaced by carbon –carbon composite to increase the lifetime of synchronizer.

    INVESTIGATION OF PERFORMANCE AND EMISSION CHARACTERISTICS OF DI DIESEL ENGINE FUELLED WITH MAHUA ETHYL ESTERS

    By Radha Krishna Gopidesi *1, Premkartikkumar SR2, Naveen Kumar Chinthala3, Narendra Kumar S4

    Abstract

    The utilization of diesel engine is continuously increasing due to higher fuel to power ratio and efficient. But, it causes increasing the emissions and the fossil petroleum products are also diminishing rapidly. Thus, it is essential to substitute the diesel fuel with non-edible vegetable oils and animal fat oils. In the present investigation diesel was replaced by Mahua Oil Ethyl Esters (MOEE) with a variety of compositions (M10, M20, M30, and M40) to analyse the performance and the emission characteristics of the diesel engine. In the present experimental work, the engine was made to run on constant speed at varied load conditions. Based on the performance analysis of present investigation M30 gave enhanced results, compared to the pure diesel and the other blends. Therefore, M30 was taken as an optimized blend. For that blend, the air preheating and supercharging was used. The air pre- heating at 60ºC of M30 showed the improvement of mechanical efficiency and brake thermal efficiency when compared with the diesel and all other blends of MOEE. Since, the blends of MOEE have more oxygen content it reduces the emissions of HC, CO, and Smoke compared to pure diesel.

    MISFIRE DETECTION IN I.C. ENGINE USING MACHINE LEARNING APPROACH

    By Sumedh Mulay1, V. Sugumaran1 and S. Babu Devasenapati2

    Abstract

    Misfire is one of the major problem associated with the engine as it leads to power loss along with exhaust of air-pollutants like HC, CO, and NOx. Maintenance and condition monitoring of an IC engine is a very crucial activity which requires restriction of emission to the least possible levels. For misfire detection, vibration signals from engine cylinder were obtained using the piezoelectric accelerometer. As engine misfire gives specific vibration signal pattern with respect to the cylinder where misfire took place. Further, 12 statistical features like Standard Error, Sample Variance, Skewness etc. were extracted from obtained signals. Out of these, only useful features were identified using the J48 decision tree algorithm. Classification via Regression, IBk were used as classifiers for classification of these selected features. This paper deals with the comparative study of these classifiers and ensembling these classifiers using Vote classifier and from that, the better algorithm for misfire detection system is suggested.

    AN EXPERIMENTAL STUDY ON TERNARY BLEND BASED STEEL FIBRE REINFORCED GEO POLYMER CONCRETE

    By M. Jothilingam1, Pratheeba Paul2,

    Abstract

    Cement is the second most consumed product and as per the year 2010 status the quantity assessed was 3.3 billion tons at global level. Cement industry accounts for 5% to 8% of world’s carbon dioxide emissions. It is also well-known fact that cement production consumes large amount of natural resources such as limestone, chalk, clay, etc. which are extracted from the quarry by blasting. On the other hand, Thermal Power Plants generates huge quantities of Fly ash while utilizing the coal for their process. As assessed by Central Electricity Authority, the total quantity of Fly Ash generated during 2015-2016 in India was 83.64 million MT. As per the Report of Indian Minerals year book 2014 issued by Ministry of Mines, Government of India, around 10 million tons of Blast Furnace slag is generated in India from iron & steel industry. Substantial quantity of this fly ash and GGBFS are used for landfills only. Both fly ash and GGBFS exhibits Cementitious as well as pozzolana characteristics. So, fly ash and GGBFS can be effectively utilized for production of concrete. One of the current research trends in Civil Engineering is to find an alternate material for Cement concrete. Geo Polymer Concrete is one such alternate for Cement Concrete. But, steam/ heat curing is required for producing Geo Polymer Concrete which makes it difficult for using the same for in situ applications. This project aims at finding the viable solutions for producing cast-in-situ geopolymer concrete without compromising on mechanical and durability properties of geopolymer concrete by using locally available industrial wastes such as Fly Ash & GGBS. The compression and flexural strength along with durability properties of Geopolymer concrete were investigated in this work. This study consisted of casting cubes and prisms and curing was done at ambient temperature to suit the cast-in-situ conditions. The specimens were tested for 7 & 28 days strength. Durability studies were carried out after the age of 28 days. It can be concluded that Geopolymer concrete can be produced cast-in-situ without any special curing requirement such as steam/ heat curing, and without compromising on mechanical and durability properties

    By P. Ganeshan1*, V. Ragavan1, P. Raju1, S. Karthigayan2, M. Nimalan1, V. Mathan Raj1, S. Naveen Prakash1, K. Praveen Kumar1, P. Rajkumar1

    Abstract

    Biodiesel nowadays is emerging as an alternative fuel which is a good replacement to the petroleum diesel. Biodiesel is mainly derived from fats and oils by different methods such as dilution, pyrolysis, micro emulsification and transesterification but these days most commercial method used for bio-diesel production is 2methyltetrahydrofuran transesterification. Biodiesel was prepared using transesterification process by optimizing the production parameters such as alcohol to oil molar ratio, catalyst concentration etc. Engine design also plays an important role as if it is improved it reduces fuel consumption and give better performance parameters. In this thesis the main emphasis has been laid on optimum production of biodiesel from neem oil and then using the biodiesel blends with diesel studying the comparative exhaust emission characteristics and engine performance. A four stroke single cylinder compression ignition engine was used to measure performance and emission parameters. Biodiesel (fire point and calorific value) added to the diesel (fire point and calorific value) at Three different volume concentrations i.e. 10, 20, &30 of Biodiesel and to blend the Biodiesel with 2-Methyltetrahydrofuraneto study the emission levels.

    Abstract

    The main purpose of this alternate cooling system is to circulate cooling air to the surrounding that means it will act as an air cooling system. Instead of using water, ice cubes are used here. The exhaust fan plays a main purpose of the exhaust fan is to suck the air from the closed area (polystyrene container) and supply to surrounding. The polystyrene box is nothing but the thermocol container and it is shaped into required dimensions for fitting the exhaust fan at the center of the box. The sufficient ice cubes are kept inside the box. Once the ice bars are filled into the closed container the vapour arises, after completing all the setting process the exhaust fan is switched to ON position, so that it exhausts the vapour to the surrounding. The cooling capacity is measured with the help of digital thermometer and the temperature is to be noted for every 2 hours so that the verification of the cooling capacity is to be done.

    COMPUTATIONAL FLUID DYNAMICS ANALYSIS OF FINNED TUBE DEHUMIDIFIER FOR SOLAR HUMIDIFICATION DEHUMIDIFCATION DESALINATION PLANT

    By B. Monarch1, V. Tejasvi1, C. Chiranjeevi1*, T. Srinivas2 and R. Shankar2

    Abstract

    Desalination by air Humidification Dehumidification (HDH) is one of the upcoming technologies of converting brackish water into freshwater. It works by evaporating the brackish water and humidifying air passing over it, leaving the salts behind. The humidified air is then passed through the condensers to recover the water it carries by condensation of water vapour. This condensed water is free from salts and can be directly used or can be further treated for use. The use of a compact finned tube heat exchanger for the purpose of the 2nd dehumidifier in a two stage HDH process is carried out by using computational fluid dynamics (CFD) analysis. The boundary condition for the computational work is obtained from experimental setup in a pilot plant. As CFD models can take up very large computational power for solving fin structures, the model is solved by modelling the fins side of the dehumidifier as a porous medium. The water yield obtained from condensation, thermal characteristics of the fluid model are obtained is compared with experimental results. The yield of water obtained is 3848 ml/hour for the first set of experimental observations.

    TYRE PRESSURE MONITORING SYSTEM USING STATISTICAL ANALYSIS AND ROTATION FOREST ALGORITHM

    By Anoop P.S. and V. Sugumaran

    Abstract

    Tyre pressure monitoring systems (TPMS) are dedicated vehicle systems, which is to calculate the vehicle tyre pressure at any condition. Direct tyre pressure monitoring systems use normal pressure sensors to measure the pressure which is fitted within the tyre. These systems are accurate and they need batteries and wireless sensors. An indirect TPMS uses the sensor data from the wheel speed sensor of the anti-lock breaking system and compares them to determine a pressure difference. This paper suggests a new and reliable vehicle tyre pressure supervise hardware using rotation forest algorithm. Vertical wheel hub vibrations are extracted using an accelerometer. The statistical features are acquired from the accelerometer data and the features are classified using rotation forest algorithm. A reasonably good percentage (93.33%) of classification accuracy was attained from the experiment.

    ARTIFICIAL LIMB MOVEMENT SYSTEM USING K-STAR ALGORITHM - A DISCRETE WAVELET TRANSFORMATION APPROACH

    By V.V. Ramalingam*1, S. Mohan2, V. Sugumaran3, B. Rebecca jeyavadhanam4

    Abstract

    Machine learning is one of the promising areas which contributes to human rehabilitation and this statement can be substantiated by the number of researches conducted in this field. In this study, we attempt to direct an artificial limb system with the help of Electroencephalogram (EEG) signals. EEG signals are created as a result of brain activities when humans intend to perform any action. Hence, capturing this signal and using them to control the artificial limb will be as close to how a human will control their normal hand. Four separate “classes of EEG signals were recorded from” 27 healthy subjects while they were instructed to perform various hand movements such as Finger open (Fopen), Finger close (Fclose), Wrist counterclockwise (WCCW) and Wrist clockwise (WCW). The recorded EEG signals were further classified with classification algorithm to identify the desired movement. Feature extraction, feature selection and feature classification are the three important phases of machine learning which needs to be focused on. The aim of this study is to mine Discrete Wavelet features from EEG signals, classify them with K-Star algorithm, and propose the best features that can be used to regulate the artificial limb.

    LIFETIME MAXIMIZATION OF WIRELESS SENSOR NETWORKS IN A WIND TURBINE

    By Indhu R1*, Sankaran R A2, Sugumaran V3

    Abstract

    Wind turbines are installed in remote places and operated continuously which demands continuous condition monitoring systems for effective utilization. The condition monitoring of wind turbine is using machine learning approach is an established area. While the initial cost of the wind turbines are higher, the additional cost introduced by the condition monitoring system makes the situation worse. The fault diagnosis technique is employed using wireless sensor networks (WSN) wherein one sensor node is attached to every wind turbine in which the fault diagnosis is done. A sink node receives the signals from all the wind turbines and all the operations are carried out in the sink node. A major issue in WSN is that the battery of the sensor nodes will reduce gradually with time, as the location of the sensor nodes are very far from the sink node in many wind turbine plants. The effective operation of the WSN based fault diagnosis system is greatly dependent on number of wind turbines per base station of the wireless sensor network. In the present work, the machine learning technique is used for the extracted vibration signals from the wind turbine bearing. The wind turbine plant is equipped with the wireless sensor network and found that when the base station is in the middle of the wind turbine plant, three wind turbines has to be kept for one base station. The simulation is done using Matlab©.
