Research Projects

• Developed methods for generating patient-specific heart models and perfoming biomechanics simulations to match measured clinical data.
• Developed GPU algorithms for accurately evaluating geometric moments of solid objects. The algorithms were able to calculate volumes and center of masses of different solid models accurately and faster than the commercial solid modeling kernel ACIS.
• Developed a unified framework for using GPUs to accelerate CAD systems. The framework was used to accelerate silhouette curves extraction and clearance computations. The algorithms are more a two orders of magnitude faster than commercial solid modeling kernel ACIS.
• Developed a software tool that can be used to optimize process parameters for cleaning cast components. The software can import standard CAD models and simulate water-jet cleaning using ray-tracing and estimates the impact pressures and cleaning effectiveness.
• Developed fast algorithms that utilize the GPU to accelerate NURBS (Non-Uniform Rational B-Spline) modeling operations. The algorithms enable direct sketching, interactive trimming, and accelerated surface-surface intersections of NURBS surfaces.
  
• Developed a method for fast evaluation and display of trimmed NURBS surfaces using GPU. The method reduced the computation time by at least 50 times over conventional CPU-based methods.
  
• Used finite element analysis to determine the dynamic characteristics of an artificial heart valve at Michigan State University. The integrity of the valve was predicted from the results of the analysis. The results agreed closely with the experimental observations.
• Developed ultrasonic simulation model to simulate ultrasonic wave propagation in any material at GE Global Research Center, Bangalore. The model uses ray tracing to calculate the ultrasonic field intensity. The model is applicable to any complex geometry and is faster in terms computational time.
• Developed Post processing software (in VC++) for HAL for processing ultrasonic C-Scan Data under the guidance of Prof. Krishnan Balasubramanian. The software has advanced image-processing capabilities and automated the process of defect classification and sizing.
