Haptic Training Method Using a Nonlinear Joint Control[Full-Text]
Jarillo-Silva Alejandro, Domínguez-Ramírez Omar A., Parra-Vega Vicente

There are many research works on robotic devices to assist in movement training following neurologic injuries such as stroke with effects on upper limbs. Conventional neurorehabilitation appears to have little impact on spontaneous biological recovery; to this end robotic neurorehabilitation has the potential for a greater impact. Clinical evidence regarding the relative effectiveness of different types of robotic therapy controllers is limited, but there is initial evidence that some control strategies are more effective than others. This paper consider the contribution on a haptic training method based on kinesthetic guidance scheme with a non linear control law (proxybased second order sliding mode control) with the human in the loop, and with purpose to guide a human user's movement to move a tool (pen in this case) along a predetermined smooth trajectory with finite time tracking, the task is a real maze. The path planning can compensate for the inertial dynamics of changes in direction, minimizing the consumed energy and increasing the manipulability of the haptic device with the human in the loop. The Phantom haptic device is used as experimental platform, and the experimental results demonstrate.

Impact Of Leverage On Firms Investment Decision[Full-Text]
Franklin John. S, Muthusamy. K

The present paper is aimed at analyzing the impact of leverage on firm's investment decision of Indian pharmaceutical companies during the period from 1998 to 2009. To measure the impact of leverage on firm's investment decision, pooling regression, random and fixed effect models are used by taking, leverage, sales, cash flow, Return on Asset, Tobin's Q, liquidity and retained earnings as independent variable and investment as dependent variable. In addition , we demarcate between three types of firms (i) Small firms, (ii) Medium firms and (iii)Large firms. The results reveal that a significant positive relationship between leverage and investment, while we found a negative relationship between leverage investment for medium firms and positive relationship between leverage and investment in large firms. Our econometric results reveal an insignificant relationship between the two variables for medium and large firms.

Effect of Nanofluid Concentration on the Performance of Circular Heat Pipe[Full-Text]
M. G. Mousa

The goal of this paper is to experimentally study the behavior of nanofluid to improve the performance of a circular heat pipe. Pure water and Al2O3-water based nanofluid are used as working fluids. An experimental setup is designed and constructed to study the heat pipe performance under different operating conditions. The effect of filling ratio, volume fraction of nano-particle in the base fluid, and heat input rate on the thermal resistance is investigated. Total thermal resistance of the heat pipe for pure water and Al2O3-water based nanofluid is also predicted. An experimental correlation is obtained to predict the influence of Prandtl number and dimensionless heat transfer rate, Kq on thermal resistance. Thermal resistance decreases with increasing Al2O3-water based nanofluid compared to that of pure water. The experimental data is compared to the available data from previous work. The agreement is found to be fairly good.

Performance and Emission Characteristics of Stationary CI Engine with Cardnol Bio fuel blends[Full-Text]
Mallikappa, Rana Pratap Reddy, Ch.S.N.Muthy

The compression ignition engine is the most popularly used prime mover. The compression ignition (CI) engine moves a large portion of the world's goods & generates electricity more economically than any other device in their size range [1]. All most all the CI engines use diesel as a fuel, but the diesel is one of the largest contributors to environmental pollution problems. The application of bio diesel as a substitute for conventional petroleum fuel in diesel engine gain ever increasing demand throughout the world wide, because it is produced from renewable resources, bio degradable and potential to exhaust emissions & use of bio diesel in diesel engines generates rural employment opportunities by cultivating such oil producing crops[1-5]. In this research work the detailed investigation on performance and emission characteristics of four stroke single cylinder engine with variable loads were studied, cardnol bio fuel volumetric blends like 0, 10, 15, 20%, and 25% were used. The results indicate that brake power increases (by 76% approximately) as load increases. Brake specific energy con-version decreases (by 30-40 % approximately) with increase in load. Brake thermal efficiency increases with higher loads and emission levels (HC, CO, NOX) were nominal up to 20% blends.

Bus Proximity Indicator - (An Intelligent Bus Stop)[Full-Text]
Prof. A.P. Thakare, Mr. Vinod H. Yadav

It is always a good idea that a bus commuter waiting at a stop gets to know how far a bus is. If his route of travel happens to be common for more than one bus- route number, it is even better for him to know which is the nearest bus or the earliest arriving bus. This will enable him to opt for the bus or some other mode of commuting. This becomes very useful for the physically challenged commuter, as after knowing in advance the bus arrival s/he will be ready to accommodate in the bus. A thought of project "Bus Proximity Indicator" is the best solution for the above situation and is best suitable for the B.E.S.T. (The Brihanmumbai Electric Supply & Transport) In this a wireless RF linkage between a certain bus and a bus stop can be used for determination of the bus proximity that help's commuter to know how far his bus is. This project tells him the Bus number, bus name and the approaching time by displaying it on the LCD which is on the bus stop. This project also satisfies the need of automization in bus services.

Improved Performance of M-ary PPM in Different Free-Space Optical Channels due to Reed Solomon Code Using APD[Full-Text]
Nazmi A. Mohammed, Mohammed R. Abaza and Moustafa H. Aly

Atmospheric turbulence induced fading is one of the main impairments affecting the operation of free-space optical (FSO) communication systems. In this paper, the bit error rate (BER) of M-ary pulse position modulation (M-ary PPM) of direct-detection and avalanche photodiode (APD) based is analyzed. Both log-normal and negative exponential fading channels are evaluated. The investigation discusses how the BER performance is affected by the atmospheric conditions and other parameters such as the forward error correction using Reed Solomon (RS) codes and increasing Modulation level. Results strongly indicate that, RS-coded M-ary PPM are well performing for the FSO links as it reduces the average power required per bit to achieve a BER below 10^-9 in both turbulence channels.
