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          
 The Role of Density Gradient in Liquid Rocket...  
 
Abstract    
 Experimental and analytical studies were conducted to investigate key physical mechanisms responsible for flame-acoustic coupling during the onset of acoustically driven combustion instabilities in liquid rocket engines (LREs). Controlled experiments were conducted in which a turbulent hydrogen-oxygen (GH2-GO2) diffusion flame, established downstream of a two-dimensional model shear coaxial injector was acoustically forced by a compression driver unit mounted in a transverse direction and excited through a broad range of frequencies (200Hz-2000Hz) and amplitudes. Characteristic interactions between flame and acoustics visualized through OH* and CH* chemiluminescence imaging and dynamic pressure measurements obtained using high frequency dynamic pressure transducers indicated that small acoustic disturbances could be amplified by flame-acoustic coupling under certain conditions leading to substantial modulation in spatial heat release fluctuations. Density gradient between fuel and oxidizer was found to significantly affect the way acoustic waves interacted with density stratified flame fronts. The particular case of an asymmetric flame front oscillation under transverse acoustic forcing indicated that baroclinic vorticity, generat...

Title          
 Temperature measurements during Reentry  
 
Abstract    
 This experiment is aimed at simulating the re-entry conditions encountered during the actual flight in a plasma arc jet facility and investigating the temperature distribution along with the thermal expansion on the surface of a re-entry vehicle in order to study the thermal breakdown mechanisms of the carbon-carbon composite of the leading edge of the vehicle.This test facility is designed to test a suitably sized block of the Thermal Protection System (TPS) made up of carbon – carbon composite that is currently used in these vehicles and also any newly developed materials of appropriate size for evaluation as a possible replacement. The final outcome of this project is intended to be a quantitative relation that indicates the robustness of a material and thereby its ability to qualify as a material of choice for reusable re-entry vehicles.

Title          
 JPEG Progressive mode vs Sequential mode  
 
Abstract    
 JPEG standard generally use two type of scan to transmit the image using entropy coding. One is known as progressive mode, while other is known as sequential mode. In sequential mode, every block of image is encoded in a zigzag fashion from low frequencies to high frequencies and transmitted. So, at the receive, we get information in a sequential manner from left to right blocks and top most block to bottom most. While in progressive mode, the encoding for all blocks are done at the same time for same frequency components. So, the DC component of each block is encoded together, followed by first frequency components of all the blocks and so on. Since, progressive mode uses the information from all blocks at the same time, it is useful to implement JPEG using progressive mode for large image sizes. As in that case, information about DC and low frequency components can give average information about image. User can then download the complete image, if he feels the need to store that image. Progressive scan is also efficient in coding because different Huffman table can be used to encode different frequency components. Hence, performance of progressive scan is expected to be better than sequential mode.

Title          
   
 
Abstract    
 This is an essay written in response to a question asking whether Eugene Delacroix and his famous painting La Liberté Guidant le Peuple (Liberty Leading the People, 1830) are examples of the modernist movement or not. The essay supports the former notion using arguments largely drawn from the artwork itself. Delacroix is considered by some to be among the founders of the modernist movement; as Baudelaire commented about him, “The last of the great artists of the Renaissance and the first modern”. Delacroix’s art was often significantly marked with political messages, as is the case with Liberty leading the People, and we will see how this entire concept is modernist in nature.

Title          
 MATLAB Tutorial for processing Signals and Sy...  
 
Abstract    
 This tutorial is available as a supplement to the textbook Fundamentals of Signals and Systems Using Matlab by Edward Kamen and Bonnie Heck, published by Prentice Hall. The tutorial covers basic MATLAB commands that are used in introductory signals and systems analysis. It is meant to serve as a quick way to learn MATLAB and a quick reference to the commands that are used in this textbook. For more detailed information, the reader should consult the official MATLAB documentation. An easy way to learn MATLAB is to sit down at a computer and follow along with the examples given in this tutorial and the examples given in the textbook. The tutorial is designed for students using either the professional version of MATLAB (ver. 5.0) with the Control Systems Toolbox (ver. 4.0) and the Signal Processing Toolbox (ver. 4.0), or using the Student Edition of MATLAB (ver. 5.0). The commands covered in the tutorial and their descriptions are also valid for MATLAB version 4.0.

Title          
 Primitivism in Paul Gauguin's Where Do We Com...  
 
Abstract    
 This paper first explains how Paul Guaguin was a modernist and then explores the primitivistic aspects of his masterpiece D'où Venons Nous? Que Sommes Nous? Où Allons Nous? (Where Do We Come From? What Are We? Where Are We Going?, 1898) . The painting portrays a series of Tahitian women progressing through various stages of life. It is also rich with symbols such as idols and animals - all these features support the argument for primitivism as explained in the paper.

Title          
 A Comparative Study of Different Face Recogni...  
 
Abstract    
 Automatic face recognition is a classic problem in the area of computer vision research. This problem is still a very active area of research in vision community. The primary reason for this problem to get so much attention is the fact that face recognition finds application in many commercial applications and can work as a biometric in many law enforcement applications [1]. The problem of Automatic face recognition can be formally defined as follows: Given a set of representative training images for each person in the database, determine the identity of a new face images from the stored data. There have been several techniques proposed in literature to extract different type of features related to shape, color, etc. of the face. Some of the techniques simply use the image pixel values as the features and reduce the dimension of these features by applying some constraints such that classifcation property of training image is preserved.In this report, we discuss some of these methods which are widely used in literature and promise to exhibits good recognition accuracy. We will use Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), Sparse representation and Random projection for the task of face recognition and ...

Title          
 Supersonic Nozzle design by Method of Charact...  
 
Abstract    
 Using the 2D Method of Characteristics (MOC), the contour of a two dimensional minimum-length nozzle for the expansion of air to a design exit Mach number of 2 is computed and graphed. The problem is extended to include a nozzle with a finite expansion section which is a circular arc with a diameter equal to three throat heights. C++ source codes for the 2 nozzles are included. By inputting the values of gas constant, test section mach number, throat height and level of precision one can design nozzles for different working fluids at different test section mach numbers.

The report was generated as a part of a graduate course on compressible aerodynamics taught that semester by Dr John D Anderson. His book entitled 'Modern Compressible Flow - with Historical perspectives' contain a good chapter on the use of the MOC in designing supersonic nozzle contours (Chapter 11 of the third edition).
