Pages: 1 - 3
In this paper, we propose a work of prose developed hardware architecture of face-detection module for mobile authentication. We used MCT and Adaboost learning technique as basic algorithms of face-detection authentication to reduce the size and increase the efficiency of authentication. We have designed and verified the hardware module of face-detection engine for high-performance and real-time processing in portable mobile systems. The developed code may have an advantage in real-time processing, low power consumption, high performance and low cost.

Pages: 4 - 11
Design of motor driven household elevator chair†is a theoretical design of a hoisting system which will carry old and physically impaired people between various floors of a multistoried building. These people due to their disability can’t use conventional staircase. The system is a modification of an elevator driven by rope and pulley in which the cabin is replaced by a chair. Thus the system will carry only one person at a time. Also as compared to conventional elevators which are used between several floors, this system is used only for one to two floors hoisting. Thus the system is cheaper than conventional elevator and can be afforded and used by individual families.

Year: 2014, Volume:1, Issue : 5
Pages: 12 - 19
The study was conducted to develop a procedure to analyse characteristics: current in the coils, velocity of the fluid and force on the piston of Magneto-Rheological (MR) fluid and its behaviour in a damper. Using COMSOL multyphysics values of force applied on the piston were obtained and compared with the values obtained by experiment of Y. K. Lau and W. H. Liao and also the values obtained by finite element analysis of Benedetto Allotta, Luca Pugi and Fabio Bartolini. It was observed that the ratio of the value obtained by Y. K. Lau and W. H. Liao to the results obtained in this study decreases as the current increases. The magnetization factor “α†to match the study result with experimental results of Y. K. Lau and W. H. Liao has been calculated as a function of current(I) as: α = 0.7858 × I-0.375.

Helioshphere and Cosmic Rays Modulation Due to Solar Outputs.

Physics
Year: 2014, Volume:1, Issue : 5
Pages: 20 - 22
Based on the observation from Omniweb data centre for solar- interplanetary data and monthly mean count rate of cosmic ray intensity (CRI) variation data from Oulu / Moscow neutron monitors during 23/24 solar cycle. It is observed that Solar variability controls the structure of the heliosphere and produces long-term as well as short-term changes in cosmic ray intensity, during minimum solar activity period the sun is remarkably quiet and the strength of the interplanetary magnetic field has been falling off to new low levels, reduces the GCR entering inner- heliosphere and it is high anti-correlation between sunspot number & GCR flux. It is also found that 10.7 cm solar radio flux, velocity of solar wind and the strength and turbulence of the interplanetary magnetic field with count rate of cosmic ray intensity are inverse correlated.

Pages: 23 - 25
This paper reviews about the Potential applications of thin film Photovoltaic (PV) Cells with a common goal of producing high power efficiency of the solar cells by reducing the size of silicon wafers. A new field of nanotechnology has opened up and promising possibilities to reduces the heating effect in the material with thin film PV cells. We discuss about the light trapping effect for cell efficiency using the high surface area in 3-D hierarchical ZnO nanostructures. CdTe thin films were made using a layer-by-layer deposition process consisting of spin coating colloidal CdTe Nano crystals followed by a sintering step.

Pages: 29 - 30
Plant tissue culture series of culture techniques used to grow plants in-vitro. Major components which plays role in culturing plants in-vitro are light-temperature maintenance, type of media used, type of enzymes provided for the growth of plants. In plant tissue culture laboratories, major cost is involved in maintenance of light and temperature. Current or traditional method of illumination in plant tissue culture laboratories is down-ward illumination method. This paper suggests sidewise illumination method thorough which number of tube lights is reduced. Lumen method and point calculation method of illumination calculation is used. It has environmental benefits like energy conservation and has economic benefits as well. Area uncovered in range of light is found to be more in down-ward illumination method than in side wise illumination.

Plant tissue culture series of culture techniques used to grow plants in-vitro. Major components which plays role in culturing plants in-vitro are light-temperature maintenance, type of media used, type of enzymes provided for the growth of plants. In plant tissue culture laboratories, major cost is involved in maintenance of light and temperature. This paper suggest several strategies to be applied in plant tissue culture lab through which cost of production can be reduced and environmental benefits like energy conservation, water conservation can be achieved. Strategies like change in illumination method, waste water reutilization, reuse of plastic bags and trays, natural illumination, etc can be environmentally beneficial. Investment required for implementing strategies are less than economical benefits obtained hence it is cost beneficial as well.

EXPERIMENTAL STUDIES OF DOUBLE PIPE HELICAL COIL HEAT EXCHANGER WITH MICRO FINS

MECHANICAL
Year: 2014, Volume:1, Issue : 5
Pages: 33 - 37
This paper revel's the heat transfer characteristics, flow friction characteristics, of a horizontal tube-in-tube heat exchanger for single phase heat transfer with water as the working fluid. The material used for the construction of heat exchanger is copper, owing to its high thermal conductivity. The various techniques for achieving improved heat transfer are usually referred to as "heat transfer augmentation" or "heat transfer enhancement" and the heat exchanger provided with heat transfer enhancement techniques as "Augmented Heat Exchanger". The objective is to reduce as many of the factors as possible capital cost, power cost, maintenance cost, space and weight, consistent with safety and reliability. Paper describes the principal techniques of industrial importance for the augmentation of single phase heat transfer on the inside of tubes namely "Micro fin". So micro fins should be used in heat exchanger when high heat transfer rate is required and pressure drop is of no significance. The obtained results show that the Nusselt number in the tube with the micro fin increases. It was observed that, based on constant flow rate, the heat transfer rates for finned heat exchanger were found to be more than the plain tube.
