    • A Stochastic dynamical system for edge detection 

      Uma, K
      A new stochastic algorithm for edge detection has been presented. This algorithm is based on time-homogeneous Markov chains with the same kind of transition probabilities as in Monte Carlo algorithms and is inherently ...
    • Excitation dynamics in GaAs quantum wells 

      Srinivas, Vivek
      The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ...
    • Lexicalisation of montague semantics: a unified approach to semantic interpretation 

      Srinath, R
      This thesis presents the X/LTAG model, a novel framework for semantic representation that integrates the Lexicalized Tree Adjoining Grammar (LTAG) formalism of Arvind Joshi with the possible world semantics of Richard ...
    • On the Eikonal equation and shape from shading 

      Bora, Prabin Kumar
      This thesis proposes and develops new techniques for the solution of the Shape from Shading (SFS) problem. For a homogeneous Lambertian surface, illuminated by a distant point light source in the direction (p, q, -1) ...
