With the advancement of technology, cooling demands has gone up. In order to minimize cost, it is required to find out means to enhance heat dissipation rate without much design modification of electronic component. Here, analysis is carried out to optimize heat transfer in mixed convection regime to ensure minimum pumping power and channel size modifications. A vertical enclosure with a hot plate is considered and the flow is varied to obtain forced and mixed convection. The flow is considered to be laminar with Reynolds number below 2500 and Rayleigh number below. The orientation of the electronic component is also varied to determine the best possible design. Study was conducted by analysing the heat transfer coefficient of a hot plate using air flow. By comparing hot plate at different orientations, it is observed that the heat transfer coefficient value is high when the plate is inclined at an angle of 30 for both mixed and forced convection. It’s found out the power consumption is less in case of mixed convection. So by considering a limiting region were the heat transfer rate is similar for mixed and forced convection, we can choose mixed convection mode as the optimized convection mode.

Coconut farming is one of the main cultivation in India, especially in southern states of India. It is for this Kerala is one of the largest producers of tender coconut in India. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of non-tropical countries often have had the exocarp (outermost layer) removed. The flesh inside the seed of the coconut is only edible. So it is required to dehusk the coconut, remove the fibre and break the coconut seed to access the flesh. The proposed machine a Coconut Breaker Extractor Grater which can break a de-husked coconut into two pieces, collect coconut water and grate the coconut pieces into desiccated coconut. The main highlight of the proposed project is that there is no contact between the tool and hands of the user both in breaking and grating of the coconut. For the proposed machine, it is required to introduce a de-husked coconut and fix it on the arms of the machine. The main merits of the proposed machine are it is feasible in terms of economy, time and effort, enhanced safety of the user by eliminating injuries caused primarily due to improper handling of the grater tool.

Generally used conventional stretchers have small wheels comparatively. They can be used on smooth, levelled and concrete surfaces. But they are not suitable for rough, gutter filled and earthy passages. So the usual practice is that, two or more people will lift the stretcher by hand and carry it. This practice is not reliable in all cases and it may cause discomfort to the patient as well as the persons handling it. Also there are chances that the patient may even fall down. So there arises the need for a project to overcome all these problems. The proposed project has all terrain wheels which make it suitable for carrying patients easily and comfortably through rough terrain, gutter filled paths etc. Also an efficient suspension system is provided so that the patient may feel comfortable throughout the travel. No matter what the path is the patient will experience them smoothly. Also other provisions like foam bed or gel pad may be provided to increase comfort. The proposed project finds wide applications in areas where ambulance or other vehicles could not reach like villages, forests, narrow lanes in streets and a lot more medical purposes. The proposed project is also light weight so that it can easily be lifted in emergency situations. The proposed project will ultimately help to reduce human effort, reduce manpower requirements and will provide superior comfort and care to patients.

History is a replete with battles and wars since the dawn of civilization. Right from the ancient times, the foot soldiers have fought and won the battle for the victor. However, over the past decade or so, the infantry’s role has changed - the emergence of smart munitions and precision aerial bombardment has resulted in the infantryman entering tough urban combat situations to mop up any remaining resistance. Tomorrow’s heroic soldiers aren’t going to jump into the battle with just a bullet-proof vest, a backpack sized field radio and a commando knife clutched between his teeth. Our system works on voice command given by Voice module V3. The main thing is, we have used IP camera which also uses SD card, this SD card capture and stores the image even if the communication is destructed in fact also when only camera is in motion. Thus our aim is to provide a robotic system that can combat in wars and other military purposes.
