Seminar Paper
Compressed sensing with noisy samples Sep 2010 Feb 2011
Guide Mr. Lennart Gerdes, Associate Inst. For Signal Processing, TUM, Munich
In the presence of noise, the reconstruction of the signal can be performed by solving an unconstrained minimization problem consisting of the terms data fidelity and sparsity balanced by a scalar regularization parameter. Paper deals with an algorithm that solves the minimization problem while also providing an automatic choice for the regularization parameter.
Research Paper
Intelligent Traffic Controller July November, 2007
Ajith J Kochery, Kishore R & Dr. Kris Kumar
Guide Dr. Kris Kumar, Professor, Dept of Computer Science, PESIT, Bangalore
The paper presents how road traffic management can be made much simpler using adaptive signal processing techniques. A mathematical model analogue of the road traffic density in four way junctions had been developed using Adaptive Signal Processing concepts as a surface of a paraboloid. The analysis of the paraboloids will lead to determining the traffic light intervals thereby controlling the traffic in an optimum manner. Prototype software was developed using Matlab.

Engineering Projects
1. Centralized Data Acquisition System in an Operation theatre January June, 2008
Guide Dr. Shashidhara H L, Professor, Dept of Telecommunication, PESIT, Bangalore
This project involves designing a system to interface the main equipments used by an Anesthetist, in an operation theatre to a central display unit. The doctors would be able to monitor the parameters of the interfaced equipments simultaneously by using this central display unit. Prototype software was developed using Microsoft Visual C# (.NET Framework). This project was developed for medical electronics manufacturer Larson & Turbo, Mysore, Karnataka, India.
2. Maze Follower & Fire Extinguisher Robot March 2008
This robot was designed to traverse through a maze and extinguish a fire at the end of the maze. It was built on ATmega16 microcontroller, with LM324 H-bridge for motor control. The sensory circuit consisted of infra-red transceivers for path and checkpoint detection.
Yantriki 2008 The robot was ranked 7/30 robots in an Inter College Robotics Contest Yantriki, held by RV College of Engineering, Bangalore, Karnataka.
3. Area Mapping, Line Following & Pattern Recognition Robot January - February, 2008
The challenge was to design a robot which can detect pattern errors on a Chess Board patterned surface of 160 cm X 160 cm size. The robot detects the pattern errors by scanning the surface and records the pattern error positions. It was built on ATmega16 microcontroller, with LM324 H-Bridge for motor control and the sensory circuit for line and pattern detection consisted of infra-red transceivers.
Automata 2008 The robot was ranked 5/50 robots in an All India Robotics Contest, Automata, held by National Institute of Technology, Karnataka.
4. Sudoku solver June - August, 2006
Guide Dr. Jagannath Raju, Director, SystemAntics, Bangalore
This application was developed on Microsoft Visual C# (.NET Framework) to solve a given Sudoku puzzle. The application solves the puzzle by generating Candidate Sets (a set of possible elements for a given cell) for each empty cell in the puzzle grid by using Sudoku constraints. A generated candidate set is scanned and the best possible candidate is selected and placed at the appropriate empty spot. After repeated iterations of Candidate Set generation and Candidate Set scanning, the algorithm converges to a solution.
