A. Research - OO & Software Engineering
Research Objective: My current research involves development of new algorithms for problems in representing Software Architecture, Components based architecture, Reuse of Architectural components, Software Architecture Implementation, Testing and Maintenance, Code Review, etc.
Research Topics: Current topics of interest include UML based OO Software Architectural Modeling, Coupling and Cohesion in OO systems, OO Software for Augmented Reality, Human Operating Systems, and Data Mining and Visualization for Financial Engineering.
Research Accomplishments: Several OO based software architectures have been derived.
My main contributions are:
1. Object Oriented Augmented Reality System: A new Animation Director architecture has been developed which demonstrates the use of a whole-part software architecture. This is developed to generate animations automatically from any dataset. The salient features of the system includes modules to handle disparate datasets, identification of algorithms to do feature extraction from large data sets, generation of navigation paths and to finally generate animations. The objective is to eliminate the human error or, in other words, the system will help the human to arrive at intelligent decisions in an efficient manner.
2. Object Oriented Human OS Architecture: Just as an OS is the life of a computer, the human OS is the system that operates as the life for a virtual human. The system integrates several parts to model, specifies animation tasks, maintains constraint information and generates human-like behavior.
3. Object Oriented FIDAVIS System: The FIDAVIS architecture encompasses a suite of algorithms from Data Mining and Visualization into one system to run on a shared address space system. The architecture currently supports simple data mining support for Currency Forex and Volume Visualization of Currency Fluctuations.
4. OO Internet Architecture: An internet architecture for all the above three software systems have also been developed. This architecture combines the recently identified method of using live data access and interactive navigation for all the above three applications.
5. OO Visualization of Unstructured Grids: Core voxelization and volume visualization algorithms have been implemented using OO mechanisms in C++. The system has been in productive use since 1993.
B. Research - Graphics & Visualization
Research Objective: My research in graphics and visualization involves development of new algorithms for problems in Volume Visualization, 3D Modeling and Graphics, Visual Simulation, Graphics Hardware and Parallel Graphics Algorithms.
Research Topics: Current topics of interest include interactive and immersive user interfaces, tools and techniques for interactive steering of scientific and engineering applications, visualization methods for time-varying, unstructured, and volumetric data, and parallel algorithms for visualization and computer graphics.
Research Accomplishments: Several core algorithms for volume visualization of unstructured grids have been developed and implemented.
My main contributions are:
1. Coherent Voxelization Algorithm: A new Coherent Voxelization Algorithm has been developed which demonstrates that interactive volume rendering of unstructured grids is possible. All objects in the grid are reduced to voxels, and all the rendering is done on the voxel volume. The algorithm is length, area and volume coherent and eliminates the need for sorting of polyhedra before rendering. All computations are reduced to incremental computations in one-dimensional space.
2. 3D Antialiasing Algorithm: Anti-aliased voxelization improves the quality of the voxelized data, and is demonstrated using an accumulation volume buffer (AVB) algorithm. A set of volume error measures (VEM) have been developed to quantify the quality of voxel data.
3. Parallel Algorithms: The coherent voxelization algorithm is parallelized to run on a shared address space system. Algorithms have also been developed for fast rendering of voxelized data. A pseudo rotation algorithm and its parallel implementation on shared address space systems is developed. This algorithm integrated with a shared memory voxelization helps fast previewing of unstructured grid. A new parallel algorithm for volume rendering based on a 3D pyramid structure is developed for message passing systems.
4. Hardware Architecture: A hardware architecture for interactive volume visualization of unstructured grids is also developed. This architecture combines the recently identified method of using texture mapping for volume rendering with anti-aliased voxelization.
C. Research - Financial Engineering
Research Objectives: The main objective of my research in financial engineering is to develop algorithms for parallel implementation on HPC systems related to financial engineering computations and to enhance Visualization.
Research Topics: Risk Metrics, Credit Exposure, Analytics Library, Implementation using MPI on T3E and Cray/Origin 2000.
Research Accomplishments: Several parallel algorithms for financial engineering have been developed and implemented.
My main contributions are:
1. Parallel Risk Metrics(for JP Morgan, Wall Street, New York): This work focussed on the design and implementation of parallel algorithms for financial engineering. We have successfully implemented algorithms for the computation of Credit Exposure and Real-time Sensitivities. The algorithms have been tested on a variety of commercial systems such as SGI Cray Origin 2000, Cray T3E, IBM SP2 and a cluster of SUN Sparc systems. We also explored the possibility of using the parallel I/O library of the Cray T3E to remove the I/O bottleneck.
2. FEVolumes - Financial Volume Visualization: Our goal of this research is to demonstrate the feasibility of volume visualization for financial engineering algorithms. We have achieved this using volume modeling for a variety of FE Algorithms and show results of volume rendered images. And we have also extended this modeling scheme to run on the Internet environment with live access to realtime data. The system currently has been deployed for production use in a real world Financial Engineering organization.
3. FIDAVIS Data Mining: This effort is to build an infrastructure for Data Mining and Visualization for Financial Engineering.
