Pages: 1 - 2
Liquid dispenser machine is commonly found in our daily life in different places like offices, bus stands, railway stations, petrol pumps. In this thesis we are going to present a pneumatic operated oil dispenser machine. Using a pneumatic system interface, we can effectively increase operator accuracy, reduce training time and improve overall efficiencies, thus keeping cost down a properly designed pneumatic system interface can improve overall accuracy. Present liquid dispenser machine available in industries are costly, complex and hard in design and fabrication. Main requirement from this machine is its metering or measuring quality. Accuracy of measuring is very less in various machines. Hence, the basic theme behind this research is to improve these disadvantages of oil dispenser machine. The oil dispenser machine presently available is based on practice and past experience of the employer in his working field and also, its efficiency declines at a greater rate after a period of time. By surveying the present machines and comparing their present limitations, new model will be fabricated so that designs data can be obtained to formulate experimental data based model for this process. The design of model will be so simple that it can be adopted easily by small industries & automobile workshop. Easy technology will help to reduce metering problem. The present work reports the design & fabrication of oil measuring & dispensing machine which is used in small industries & automobile workshop.

Pages: 3 - 5
Wireless Sensor Networks often serve mission-critical applications in inhospitable environments such as battlefield and territorial borders. Wireless sensor and actor networks are the collection of heterogeneous elements linked by wireless medium to perform distributed sensing and acting tasks. The Actor nodes may fail for many reasons such as due of battery exhaustion, message overhead, hardware failure due to hash environment and these failures may convert the connected network into several disjoint networks that reduce the capability of network. Wireless sensor networks consist of widely distributed sensor nodes. These nodes have short energy because of its limited battery size. This low energy in turn decreases the life duration of network. The declined lifespan of network perhaps distress the application to run in-efficiently. For these reasons, many algorithms and protocols designed for wireless sensor networks which considered the energy consumption in their conception. The node failure becomes more critical when data aggregation is performed along routing paths as the data packets with aggregated data contain information from various sources and whenever one of these packets is lost a considerable amount of information will also be lost. To understand this challenges a comparative study need to done on various algorithm proposed over it.

Pages: 6 - 9
Heat transfer is the phenomena, of transfer energy (thermal energy) in between the systems or system and surroundings. And heat exchanger is the main device which is used for transfer of heat (thermal energy) in many industries like food industries, chemical industries, thermal power plant, air conditioning equipment etc. So because of heat exchanger importance, many heat enhancement techniques are adopted to improve the performance of heat exchanger. In the previous years, many research on passive techniques have been studied. This paper is the review of such techniques used in heat exchanger to improve the effectiveness. Twisted tapes, wire coils, ribs fins etc. are commonly used heat augmentation tools.

Pages: 10 - 13
Soil is a base of structure, which actually supports the structure from beneath and distributes the load effectively. If the stability of the soil is not adequate then failure of structure occurs in form of settlement, cracks etc. Expansive soil also known as black cotton soil is more responsible for such situations and this is due to presence of montmorillonite mineral in it, which has ability to undergo large swelling and shrinkage. To overcome this, properties of soil must be improved by artificial means known as in present study soil sample containing 0% ,9,18,27, of flyah & determine the value CBR test strength of soil & when get maximum strength to use same content sugar cane fiber 2%,4% ,6% fibre means cut sugar cane fibre1.5 cm and mix with fly ash .the test result showed significance decrease expansive behaviour of black cotton soil the california bearing ratio from 1.19 to 5.65 &unconfined compression ratio from 0.66 to1.43 kg/cm2 maximum dry density reached from 1.66 to 2.11gm/cc also conduct the triaxial test of soil to determine the value of soil c & Φ all the test conducted as per relevant is code of practice.

Pages: 14 - 20
The objective of this paper is to reduce the power loss and to improve the voltage profile in radial distribution system. Fuzzy and particle swarm optimization algorithm is a two-stage methodology used for placement and sizing of UPFC in this paper. To show the effectiveness of the same a complete result analysis is carried out on 33 and 69 bus systems. Power loss and voltages are calculated for the optimal locations based on fuzzy system. 50%, 80% 150%, overloading cases are also considered in this paper. The result analysis shows that the two-stage methodology effectively improves the voltages and reduces the power loss of the system.

Pages: 25 - 29
A proper and synchronized fuel injection is paramount for a good engine performance, since it provides a homogeneous combustion among the cylinders. The use of alternative fuels such as Ethanol, Methanol and Natural Gas in automotive applications has increased due to the strict environmental regulations. These are used to reduce automotive emissions, especially in heavy trucks and city bus fleets. Most of these vehicles use diesel fuel as their primary fuel. Trucks and buses with Detroit Diesel engines have the option to operate using methanol as their primary fuel instead of diesel fuel.Due to the low lubricity of methanol fuel, the unit fuel injectors injecting methanol fuel have a shorter operating life than those injecting diesel fuel do.Using the computational fluid dynamics programs CFX and CFX obtained the pressure and velocity profiles for pre-selected locations in the fluid path of the injector. Locations of high and low velocity areas were determined to be performance inhibitors and possible failure points and Find the way to minimize failure points.

Solar energy is the most promising among the available green energy sources and also the panacea to the increasing global warming potential and ozone depletion. In the last three decades, various technologies have been invented for extracting the latent potential of the solar energy. Among them, the one that is still unearthed and needs to be researched is the adsorption refrigeration cycle. In the present paper, we have designed a basic adsorption chiller driven by solar thermal energy which consists of a solar collector, an adsorbent bed, a condenser and an evaporator. The model provides a maximum COP of 0.452 with a refrigeration power of 6.78 kW. Moreover, we have provided the variation of COP system and COP cycle with time. Here, we have also inferred the response of COP with variation in mass and collector area and we came to the conclusion that the COP of the present system declines if the mass exceeds 15 Kg.
