Safety has been the greatest of all concerns mankind has had in all his efforts, precisio n accuracy and perfection had been mostly accounted for this demand to be satisfied.every year a huge amount of money is just being spent by companies and organisations around the globe to make their products and systems more safe. Despite the fact that the automotive industry has rigorously worked on the safety of automobiles,over 1000000 road accidents are caused due to functional errors and unexpected damages of the automobile,where flat tyres being the major contributors to it.Analyzing the causes to flat tyres and understanding the necessity of a protective measure to prevent flat tyres we decided to build a puncture prevention guard by designing a system based on the intrinsic properties of magnets.By studying the attractive and repulsive forces, impact of magnets in static and dynamic conditions,we came up with a design of an “ Autonomous puncture prevention gaurd by magnetic system” for a 2 wheeler as an initial step. A unique plan had to be designed for this guard to be put into practical application that a systematic study of the magnets and its properties were also an inevitable part of our project.various design consideration with analysis of different metals and composites with its strength to weight ratio being our prime focus were tested and finally a design and prototype was created. This guard and its practical application is sure to make rides more safe and tension free thus saving a lot of time,money,effort and most of all,precious lives of many.

Social changes have directly affected the demand for quality products and services which is evident from greater demand for manufactured products of superior quality at a more economical price. To meet this demand of customers, sophisticated controls and equipments have been developed in all sectors adopting newer technology in association with integrating different technologies. In line with integration a revolutionary change has taken place in the field of robotics whereon robots are developed to attain higher accuracy in speed position and force control. Thus force controlled robotic arm is used to guide an operator to move in designated path accurately without actually deviating from the path. It can be used in various production areas like welding, gluing, Sequential tightening of bolts etc. The major use of these kinds of robotic arms is that we can achieve the same degree of accuracy, precision and quality produced by a skilled worker from an unskilled worker. Thus reducing unemployment in developing countries which have huge unemployment rates that too in a very less cost.
Design and Development of Eco-Friendly Refrigeration System
(2016-07-21T05:55:11Z) Karthigayan, R M; Mahiboobu; Manjunath, Yelde; Manoj
The energy crisis persists all across the globe. The supply of continuous electricity is still not available in several areas of the world and also the climatic changes and global warming demand accessible and affordable cooling system in the form of refrigerators and air conditioners. These can beovercome by using Eco-Friendly refrigerant like LPG, Biogas, Natural gas etc.. Eco friendly refrigerant is available in cylinders at high pressure. When this high pressure refrigerant is passed through the capillary tube the pressure of refrigerant is dropped due to expansion and phase change of refrigerant occurs. Due to phase change from liquid to gas latent heat is gained by the liquid refrigerant and temperature drops. Thus it acts as a refrigerant and produces cooling effect.

(2016-07-21T07:02:04Z) Manoj, R; Kantharaj, N; Praveen Kumar, A; Karthik, L
Gearless transmission which is compact and portable equipment, which is skillful and is having something practice in the transmitting power at right angle without any gears being manufactured. This project is the equipment useful to improve the quality of the gear being manufactured and can be made in less time. This project uses el-bow mechanism which is an ingenious link mechanism of slider and kinematic chain principle. This is also called as “gearless transmission mechanism” and is very useful for transmitting motion at right angles. The real time study is carried out by applying a motor to one of the shafts supported on bearings. Motion analysis is performed by running the mechanism at 15 revolutions per minute; reaction forces and reaction moment are plotted against clock run of 5 seconds by using post processor. Similar motion analysis is carried out at different higher revolutions per minute and peak values of forces and moments are taken from the plot and compared with allowable stress. Theoretical calculations are made to obtain allowable stress by making use of design data values. As a result, response of elbow rod and hub is investigated to find the permissible speed of mechanism. Further simulation is performed to verify the motion analysis results.

Renewable energy is the energy which comes from natural recourses such as sun light, wind, rain, tides and geothermal heat which are naturally replenished. Wind energy, solar energy, biomass, bio-fuel and geothermal energy are the main types of renewable energies used nowadays. All forms of energy are expensive but as time progresses renewable energy generally gets cheaper, while fossils fuels generally gets more expensive. As it is renewable, it is therefore sustainable and so will never run out. Renewable energy has minimal impact on the environment. Revolving doors produces green energy when a person passes through it which is environmental friendly. As door rotates which is connected to the shaft in turn rotates shaft around the fixed magnet. From the principle of faraday’s law it produces voltage of electric current. As the consumption of electric city is increasing day by dayas needs of people are increasing. We are mainly depending on the NON RENEWABLE source of energy like thermal , nuclear, fossil fuels for generating power. As the time goes this ends a d takes people into darkness. It is also important to save this for the future generation and find other alternatives. The power can also be generated using the energy that is being wasted during closing opening of doors.

Design and Fabrication of Manual and Automated Systems for Hydroponic Fodder
(2016-07-21T06:56:06Z) Aneesh, Gopal; Krishna, Maruthi; Naga, Chowdary; Umakanth, B.S
On the surface, the concept of putting one kilogram of grain into a hydroponic system and producing 6 to 10 kilograms of lush green sprouts, independent of weather and at any time of year, is appealing. Though it seems like growing a lot of feed, the increase in fresh weight is due to water and most often there is a reduction in dry matter weight compared with the initial grain. Hydroponically sprouting grain is less a case of growing feed and more a case of buying in grain and spending additional, sizeable quantities of time and money to change its quality and reduce its dry matter weight. The economics and application of such a production system should be carefully examined. This report evaluates the economics of producing cereal sprouts for commercial cattle production through a hydroponic system. It looks at aspects of sprouts dry matter content and nutrient quality as well as provides methods of costing and comparing sprouts with other supplements.
Design and Manufacture of 3D Digital Light Processing Stereo Lithography Apparatus Printer
(2016-07-21T06:49:44Z) Aaron, Ralston; Avinash J, Singh; Bobby Seban, John; Chethan, K
Stereo lithography or SLA is an additive manufacturing process using a container of liquid UV/light-curable photopolymer "resin" and a UV light source to build parts one layer at a time. On each layer, the UV beam traces a cross-section pattern of the part onto the surface of the liquid resin. Exposure to the UV light cures, solidifies the pattern traced on the resin and adheres it to the layer above. Photo Lithography is very simple, light illuminates the resin and the resin hardens. To be more exact a quantity of light falls/shines onto the resin, if the energy quantity of that light is high enough it will induce photo polymerization of the resin. While 3-D printers are already out in the market and doing well, there is still a need for a smaller and more cost effective design. This is what we achieve to do with our project. In a conventional DLP SLA printer the print base going into the resin container which limits the size of the product being printed to the maximum depth of the container itself! Where as in our case there is no such limit as the Z-axis is scalable as the base rises up with a bottoms up approach! The aim of the project is to design an SLA printer which works "bottom up" by using a vat with a somewhat flexible, transparent bottom, and focusing the UV light, upward through the bottom of the vat. The stereolithography machine starts a print by lowering the build platform to touch the bottom of the resin-filled vat, then withdrawing upward one layer thickness (which can be as small as 10 microns). The light source we are using is a DLP projector. This light is reflected off a first surface mirror before touching the resin. This is done to reduce the height of the printer. The UV light from the projector then writes the bottom-most layer of the desired part upward through the transparent vat bottom, and the photopolymer hardens selectively where the light strikes. An advantage of this bottom-up mode is that the build volume can be much bigger than the vat itself, and only enough photopolymer is needed to keep the bottom of the build vat continuously full of photopolymer. Often a depth of only a centimeter or two of liquid photopolymer is adequate to print tall, thin structures 10 cm tall. Thus, bottom-up printing exposes far less photopolymer resin to atmospheric oxygen and room light which can degrade or prematurely harden the photopolymer and so decreases waste of the expensive photopolymer.

(2016-07-21T05:59:56Z) Aravind, H C; Kowshik, V; Murali, G; Vikas, A
Agriculture sector being the backbone of any country’s economy, especially for a country like India. India ranks 2nd worldwide in farm output. Since the population of developing countries keep on increasing, which demands more output of agricultural products. To necessitate this demand, water supply must be adequate and wastage of water must be avoided. Hence implementing a proper method of irrigation is mandatory. India also depends on grid power for irrigation hence it is necessary for development of smart solar irrigation system. Solar energy is the most abundant source of energy and it is the solution for the today’s energy crisis, hence this system consists of a solar powered submersible water pump which is integrated with a GSM module to eliminate the manual approach of operating pump and a moisture sensor for the usage of water more efficiently. The efficiency of the solar panel is increased by adapting the auto-tracking mechanism. A microcontroller is used to monitor the whole process of the system. This system conserves electricity by reducing the usage of grid power and conserves water. This is the proposed solution for the energy crisis for farmers.

Feasibility of Electron Beam Welding on Titanium to Stainless Steel With Copper as Inter Layer and Optimization of Process Parameters by Taguchi Methodology
(2016-07-21T06:31:51Z) Rohith Shri, Hari R; Sachin Irappa, Kagal; Sandeep, Kumar A; Puneeth, Gowda K
Welding of dissimilar metals is a challenging task. The main challenge when joining dissimilar metals is the metallurgical incompatibility of the metals used. Due to this reason, it has been very difficult to produce reliable joints between Titanium and Stainless steel metals due to formation of cracks, brittle intermetallics and low strength of the joint. Hence Electron beam welding experiments were carried out with copper as an interlayer by varying weld parameters such as Accelerating voltage, Beam current, Welding speed and Gun to Workpiece distance (GTWD). Optimization of these weld parameters is done as per Taguchi methodology. Macrostructure of the joint are examined by visual inspection, helium leak detection and optical microscopy. Microstructures of the joint are examined by Scanning electron microscope. The results showed that the weld quality is satisfactory and crack free weld joints were obtained with a good depth of penetration. Analysis of variance concluded that Welding speed plays a major role in determining the DOP, followed by Accelerating voltage, Beam current and GTWD. Nominal the better S/N ratio method has been followed in this experiment to conclude the optimum value of parameters that reduces the effect of noise factors on the weld quality.

Compressed natural gas (CNG) has long been known to be a viable alternative fuel. It is a clean fossil fuel, eco-friendly and also cheaper than conventional fossil fuels. CNG powered vehicles release up to 80% less Carbon monoxide, 20% less Carbon dioxide and 45% less hydrocarbon emission compared to gasoline powered vehicles. Lately there has been higher emphasis on decreasing the emission and increasing the efficiency of Internal Combustion engines popularly known as downsizing. With strict emission standards being drafted for the near future there is a need to optimize existing technologies. The main focus of this project is to optimize the fuel combustion process by employing various methods that make the best use of the CNG characteristics. The major parameters in scope of this project encompassoptimization of air fuel mixture and conversion of lean burn to stoichiometric engine to meet subsequent emission. By incorporating such modification there is scope to improve combustion and emission characteristics of the engine.

(2016-07-21T10:43:17Z) D.S Allen, Edberg; M. Kunal, Jain; Shravan, Pallakal; B.Vinod Kumar, Reddy
In the present scenario power becomes major need for human life. Due to day-to-day increase in population and lessen of the conventional sources, it becomes necessary that we must depend on non-conventional sources for power generation. While moving, the vehicles posses some kinetic energy and it is being wasted. This kinetic energy can be utilized to produce power by using a special arrangement called “POWER HUMP”. The Kinetic energy of moving vehicles can be converted into mechanical energy of the shaft through rack and pinion mechanism. This shaft is connected to the electric dynamo and it produces electrical energy proportional to traffic density. This generated power can be regulated by using Zener diode for continuous supply.All this mechanism can be housed under the dome like speed breaker, which is called hump.The generated power can be used for general purpose like streetlights, traffic signals. The electrical output can be improved by arranging these power humps in series this generated power can be amplified and stored by using different electric devices. The maintenance cost of hump is almost nullified. By adopting this arrangement, we can satisfy the future demands to some extent.
