Title          
 Business Plan for Online Money Transfer  
 
Abstract    

This is a detailed business plan proposing an online money transfer system, very similar to what PayPal is today, that we proposed to a panel of Indian VCs in 2001 but was not funded on assumptions that Reserve Bank of India will not allow such radically different money transfer methods to be implemented. The plan, proposed at the same time when PayPal was also just getting started, allowed online transfer of money, virtual cash and micro payments, .

Title          
 Hummingbird Flight  
 
Abstract    

This paper will give a brief explanation about the kinematics and the aerodynamics of the hovering flight achieved by hummingbirds and other hovering insects. The paper will be presented in two parts. The first part will deal with the kinematics of hovering bird/insects. The second part will discuss the aerodynamics of hovering flight.

Title          
 Tunable Thermal Conductivity  
 
Abstract    

This paper lists methods for tuning and enhancing thermal conductivity. Heat transfer applications have a lot of challenges such as, raise the thermal conductivity, control thermal conductivity to be changeable within the same application, and working in very accurate applications like micro combustors and electronic etc. All these requirements couldn’t be achieved by the traditional methods of heat transfer. Therefore, a lot of techniques which are related mainly to the nanotechnology are working on these issues. In this paper we will subjected to some of the methods of tuning thermal conductivity in order to control the heat transfer process.

Title          
 Laminar Separation Bubble  
 
Abstract    

This essay focuses on the phenomenon of Laminar Separation Bubble observed at Low Reynolds Numbers. The effect of this bubble on the airfoil characteristics is discussed. Airfoils used at low Reynolds numbers have to be designed taking into consideration the finite space and time occupied by the bubble. Active as well as passive mechanisms to control/delay the formation of the bubble are also mentioned.

For conventional aircraft wings, whose Reynolds number exceeds a million, the flow is typically turbulent with the boundary layer able to strengthen itself by ‘mixing’. Consequently flow doesn’t separate until high angles of attack are encountered. For lower Reynolds numbers, the flow is initially laminar and is prone to separate even under mild adverse pressure gradient. Under certain flow conditions, the separated flow reattaches and forms a Laminar Separation Bubble (Fig. 1) while transitioning from laminar to turbulent state. Laminar separation bubble could modify the effective shape of the airfoil and consequently influence the aerodynamic performance, generally in a negative manner.

The need to understand low Reynolds number (104 to 106) aerodynamics is driven by variety of applicat...
