Pages: 174 - 180
PPy-CdS nanocomposite and multilayer thin film was deposited on Al substrate using electrodeposition technique. The presence of CdS particle in the composite film was proved using XRD and Micro-Raman spectroscopy. The roughness of the composite film was very low and it to be 4.96 nm. The fractal self-similarity of the composite films was estimated as 1.06. The resistance of PPy film along the polymer chain (sheet resistance) was 92.2 Ω and the resistance across the polymer chain (volume resistance) was 9.7 KΩ. However, the value of sheet resistance was 19.3 KΩ and the volume resistance was 43.6 KΩ for PPy-CdS nanocomposites film. Polymers acted as a corrosion protection layer for CdS nanoparticles. The rise and decay time constant of PPy-CdS nanocomposites film were obtained as 150s and 200s respectively and PPy-CdS multilayer films with bridge configuration were 203 s and 480 s respectively.

The concrete slabs used for drainage purpose are of heavy weight. Concrete slab is a common structural element of modern buildings. Concrete Slab Lifting Device (CSLD) makes it possible for an individual to lift these slabs without much effort. The device structure consists of four legs with wheels. For lifting mechanism L-shaped jaw attached to a hydraulic jack, through a vertical guide shaft is used. With the help of the lead screw arrangement provided with the jaw, the slab is gripped and with the help of a hydraulic jack the concrete slab is lifted and moved to the required place. It is very difficult to lift these slabs by an individual. Usually two or more number of workers are needed for drainage repair works. This increases the cost for repairing drainage systems. The Concrete Slab Lifting Device makes it possible for an individual to lift these slabs without much mechanical effort.

This paper presents the performance of single cylinder HCCI Engine using Biodiesel Mixture. The Homogeneous charge compression ignition (HCCI) combustion is a new trend alternative technology to current engine combustion systems. Many inventions in HCCI is being worked out to use it as a method to reduce exhaust emissions and also fuel economy. The quality of homogeneous mixture of air and fuel is the key feature of HCCI combustion. HCCI has the characteristic nearly eliminate NOx emissions while increasing efficiency as in diesel engine. HCCI adapts a pre mixture of gas-phase fuel and air being burned spontaneously and entirely by an auto ignition process. Homogeneous Charge Compression Ignition (HCCI) engines promises a high thermal efficiency combined with low levels of NOx and PM emissions. The purpose of this study is to analyze the effect of alternative fuel when used in the HCCI engine combustion process. The experiments were conducted in a modified single cylinder water-cooled diesel engine. In this experiment we use diesel and bio-diesel Mixture as the fuel at different milli second injection.

Public distribution system (PDS) i.e. Ration distribution system is the facility provided by the Government of India to ration card holders for food grains, fuel and other goods, as per the economic policy. Every family has its own ration card. The type of Ration card depends on annual income of that family. In existing PDS, subsidized food grains like wheat, rice etc. and fuel like kerosene are issued manually. So there are chances of human errors like wrong entry in register of ration shop about the amount of food grains given to the ration card holder/user. Similarly unsold food grains at the end of the month, will sale to another users without any intimation to the government and ration card holders, leads to illegal activity and corruption. To restrict such illegal activities and corruption we proposed a system called “Automatic Ration Distribution by using Raspberry Piâ€. In this system we reduced human efforts for distributing food grains by using Raspberry Pi and GSM technology thereby informing each and every activity to the ration card holder as well as Government. In our approach initially we are scanning QR code on Aadhar card instead of ration card. Then Raspberry Pi matches the user QR code and OTP for authentication purpose. If user is authenticated person then he/she will get details of allocated ration on monitor display. Then he/she will purchase the required amount of ration by entering amount through keyboard. After completion of this process Raspberry Pi will send the information to government server and user via GSM module.

INVELOX is a wind delivery system suitable for wind power harnessing. One of its innovative features is its capability of incorporating multiple wind turbine generator system in the venturi section. It’s first innovative feature is the elimination of tower mounted turbine. Secondly, INVELOX captures wind flow through an omnidirectional intake or multi-unidirectional intakes and thereby there is no need for a passive and active yaw control to orient the wind turbine. Third, it accelerates the flow within a shrouded venturi section which is subsequently expanded and release into the ambient environment through a diffuser. When two or three turbines are in the venturi section, the wind power harnessed by second and third turbine is lesser than the first turbine power conservation. The modified venturi section result shows that it is possible wind power using multistage turbine is higher. Therefor the total harnessed power of the system increases. Also doing Analysis in ANSYS software.

Nowadays most of the vehicles use the two wheel steering mechanism as their main handling system. But the efficiency of the two wheel steering vehicle is proven to be low compared to the four wheel steering vehicle. In standard 2 Wheel Steering System, the rear set of wheels are always directed forward and do not play an active role in controlling the steering. While in 4 Wheel Steering System, the rear wheels do play an active role for steering, which can be guided at high as well as low speeds. Four wheel steering system can be employed in some vehicles to improve steering response, increase vehicle stability while moving at certain speed, or to decrease turning radius at low speed. Four-wheel steering is a technologically, tremendous effort on the part of automotive design engineers to provide near-neutral steering. In situations like low speed cornering, vehicle parking and driving in city conditions with heavy traffic in tight spaces, high speed lane changing would be very difficult due to vehicle’s larger wheelbase and track width which brings high inertia and traction into consideration. Also in situations like low speed cornering, vehicle parking and driving in city conditions with heavy traffic in tight spaces, driving would be very difficult due to a sedan’s larger wheelbase and track width. Hence there is a requirement of a mechanism which result in less turning radius. In this system, all the four wheels are connected to each other by means of a single chain with the help of a sprockets and the same chain is coupled to steering wheel rod with another sprocket mounted on it. This arrangement of the wheels enables the vehicle to turn 90 degrees, without moving from the spot, i.e. the vehicle has zero turning radius. This helps in maneuvering the vehicle in tight spaces such as parking lots and within small compounds. Modern development and economical progression of Indian society resulted in increase of cars on rods. Due to space constraints, car parking is the major problem faced in most parts of the country. Present study aims for development of a system to reduce the turning radius of a car. The indigenously developed system consists of Ackerman steering and various mechanism with arrangement of the various kinematics links. In this system at first vehicle is stopped and wheels are then turned in the required direction with the help of steering system. It has turning radius nearly equal to negligible of the length of car itself. This system can be useful in better parking, traffic jam, back turning on narrow roads, etc.4-Wheel Steering System is not a new technology but it has not gained popularity over 2-Wheel Steering System even though experiments have proved that it has excellent maneuverability, high stability and it is a solution to oversteer/understeer. If 4-Wheel Steering is a better placement for age old 2-Wheel Steering, why has it not replaced it yet?

Fuels derived from the renewable biological resources for the use in diesel engine are known as biodiesel. Biodiesel produced from non-edible and edible feed stocks such as Mahua, Palm, Jatropha, Soya etc. are reported to be feasible choices for developing countries like India. In this investigation the blends of varying proportions of smart biodiesel are prepared, analyzed and compared with the performance of diesel fuel and studied using four-cylinder diesel engine at varying loads. Raw oils of five biodiesels are esterified (methyl esters) before blending with each other. The esterified oils of biodiesel blends satisfy the important fuel properties and it lead to an improvement in engine performance and emission characteristics without any design modifications in the engine. The brake thermal efficiency, SFC, Exhaust gas temperature, CO, CO2, NOX, and HC were analyzed.

Our project aims at creating a device to tap the hydraulic energy of flowing sewage water and utilize the energy for the purpose of power generation. In urban areas, flats and other multi-storeyed residential buildings employ a drainage system whereby the sewage flows through a single outlet pipe to the sewers. The grey water of the sewage flows down with a potential energy, which along with thee kinetic energy of the flowing water, could be utilized to power a mini hydro- power plant similar to those used in dams. The water would strike the vanes of a suitable Darrieus turbine of aerodynamic blade profile NACA 633018 which in turn would rotate the shaft of a generator and hence generate electricity. The blades of the turbine are fabricated using galvanized iron (GI) sheet. The generated electricity could be stored and used for primary lawn maintenance activities in a household, or even used as a form of backup energy for powering households during power scarcity.
