Influence of thermal barrier coating on combustion characteristics in a biodiesel fuelled Di diesel engine
There are so many methods are used to improve the efficiency of a diesel engine, reduced fuel consumption. For this purpose, one of the technologies is used that is ceramically coated IC engine. It is also known as Thermal barrier coating (TBC). In the present work, YSZ has used as thermal barrier coating on combustion chamber to increase the thermal efficiency and reduce the fuel consumption. In this experimentation, YSZ – TBC is done by plasma spray coating technique which is the simplest method. Production of biodiesel from algae is a promising option. The present work aims to focus on the performance of a diesel engine with algae oil as fuel. In order to use the oil in an engine, its blends with the petroleum diesel were prepared. It is found that the properties of neat algae oil and its blends are very close to the properties of neat diesel. The investigation was carried out in the single cylinder water cooled, constant speed DI diesel engine with Yttria Stabilized Zirconia as Thermal Barrier Coating with the Diesel fuel and various blends of biodiesel like B20, B40, B60, B80, and B100. Here, the investigation carried out at idle load, part load and full load conditions. The combustion characteristics were analyzed at various load conditions for baseline without coating and YSZ –TBC coated engine. Here, YSZ – TBC coated engine have better combustion characteristics compared with the uncoated engine because of the thermal barrier coating on combustion chamber which gives the high heat release rate due to its high coefficient and low thermal conductivity. The blend of B20 has higher heat release rate characteristics. The addition of fuel additives is one of the possible approaches for increases the combustion characteristics. The present work, DEE is used as additives to improve the combustion characteristics of YSZ – TBC coated engine. Among the various blends tested, B20 + 5% DEE has better combustion characteristics.

Study of unfurlable mechanism for space radars
Unfurlable rim truss antennae are considered to be the most suitable for developing large size aperture structures for space antenna. They have largely deployed to stowed volume ratio, precision, and reliability in its operation. The mechanism is capable of altering its configuration from a stowed to deployed shape to meet specific operational requirements of space-borne radar. The proposed study of unfurlable mechanism for paraboloid reflector antenna is made up number of parallelogram units comprised of links with appropriate hinge joints, which concatenate in a repeatable fashion to form the desired structure. This study include geometric modeling, kinematic simulation and preliminary structural analysis of unfurlable rim truss

Classification of fungal and bacterial leaf diseases using machine learning techniques
In Farming and Gardening, leaf diseases have grown to be a challenge as it can cause considerable reduction in both quality and measure of agricultural yields. Thus, automated recognition of diseases on leaves plays a vital role in Farming and Gardening sector. This Thesis imparts a simple and computationally dexterous method used for leaf disease identification and grading using digital image processing and machine learning method. The proposed system is divided into two phases, in the first phase the plant is recognized on the basis of the features of leaf, it includes pre-processing of leaf images, and feature extraction followed by Support vector machine and decision tree based training. In the second phase the disease present in the leaf is classified, this process includes K-Means based segmentation of defected area, feature extraction of the defected portion and the Support vector machine and decision tree based classification of disease. Then the disease grading is done on the basis of the amount of disease present in the leaf.

Sensitive label privacy protection on social network data
Privacy is one of the fundamental issues when publishing or sharing social community data for social technology studies and business evaluation. Lately, researchers have developed privacy models much like okay-anonymity to save you node re-identification via shape data. However, even if those privacy fashions are enforced, an attacker may still have the ability to deduce one’s private statistics if a group of nodes in large part share the same touchy labels (i.e., attributes). In other words, the label-node courting isn't always nicely covered by pure structure anonymization methods. Moreover, current strategies, which depend upon area enhancing or node clustering, may also significantly alter key graph properties. Items shared through Social Media may affect more than one user’s privacy e.g., photos that depict multiple users comments that mention multiple users, events in which multiple users are invited, etc. The shortage of multi-celebration privateness management guide in modern mainstream Social Media infrastructures makes users unable to as it should be manipulated to whom those objects are absolutely shared or no longer. Computational mechanisms which can be capable of merge the privacy preferences of more than one customer’s right into an unmarried policy for an item can assist resolve this problem. But, merging more than one customers’ privateness preferences isn't always a smooth venture, because privateness options may war, so techniques to clear up conflicts are needed. To tackle this problem, in this, we propose the first computational mechanism to resolve conflicts for multi-party privacy management in Social Media with privacy policy inference of user-uploaded images that is able to adapt to different situations by modeling the concessions that users make to reach a solution to the conflicts.

An experiment of improvement in solar panel efficiency using solar concentration by number of mirrors
Energy demand in India increasing as population growth increasing but it is difficult to fulfill energy demand as the resources are limited. India has a significant capacity for solar energy generation from renewable energy sources - solar photovoltaic, solar thermal, small water, wind, biomass, bio fuels and others. While proven technologies have emerged over the last few decades, the economical practicality of renewable energy is yet to be achieved and requires creation and adoption of innovative business and financial models. India’s energy problems include: Over 40 per cent of the households in India still don’t have electricity. One third of our total energy availability is from non-commercial sources (organic manure and fertilizer). Per capita energy consumption is one third of the world's average and per capita electricity consumption. India faces a supply gap of about 11% shortage and 14% of peak power shortage supply demand. Solar energy is at forefront of clean, renewable energy, and this pace is increasing due to the progress in solar panels production and efficiency as well as rapid unstable fuel costs. Photovoltaic (PV) solar cells are the most easily achievable solar technology, and they work best in bright days, in which the event does not have little or an obstacle in the sunlight. Photovoltaic (PV) technologies convert energy into electricity directly from the sunlight. Sunlight semiconductor strikes the substance and produces electrons, releasing electrons from their nuclear bonds. PV panels have no moving parts and usually live with less maintenance for twenty years or more. Landlords can set up PV panels to reduce or eliminate their monthly electricity bill, and utilities can create large "farms" of PV panels to provide pollution-free electricity to their customers. When the sun is at its highest point in the sky, then the power generation can offset the costly electricity generated when daily demand is greatest. Concentrated photovoltaic technology (CPV) uses optics such as mirrors and lenses to focus on sunlight on solar cells to generate electricity. CPV benefits on photovoltaic concentration because it is the number of solar cells required for the same power generation. With the duration and intensity of the sunlight, the temperature also puts a big impact on the performance of the PV module because high temperature reduces production efficiency. This experiment tells a practical approach to increase the efficiency of the solar panel by the number of uses of the mirror mechanism. These reflectors are cheap, easy to use, quite simple to use and no additional equipment or device is required to use. But experimental results show a remarkable increase in the overall production of solar panel. Experimental readings received from (a) without reflectors, (b) with one reflector, (c) with two reflectors and (d) with three reflectors.) with numbers of reflectors are compared.
