Some Problems Of Continuum Percolation., Anish Sarkar Dr. Dec 1996

Some Problems Of Continuum Percolation., Anish Sarkar Dr.

Doctoral Theses

The model of continuum percolation can be described as follows. We start with a homogeneous Poisson point process X. At each point of X we centre a ball with a random radius such that the radii corresponding to different points are independent of each other and also independent of the Poisson process X. In this way, the space is divided into two regiorns, the covered region or the occupied region consisting of the region which is covered by at least one ball, and the uncovered region or the vacant region which is complement of the covered region. In this dissertation …


On Three Dimensional Digital Topology And Its Application To Image Processing., Punam Kumar Saha Dr. Jul 1996

On Three Dimensional Digital Topology And Its Application To Image Processing., Punam Kumar Saha Dr.

Doctoral Theses

Digital topology provides a sound mathematical basis for object classification, counting and labeling, border tracking, contour filling, thinning, segmentation and many other image processing applications. An important characteristic of topo- logical properties is that they are invariant under translation, rotation, and more generally under any elastic deformation. The analysis of three dimensional (3D) digital images has generated increasing interest with the rapid growth of 3D image processing applications including computer vision. 3D digital images are common input/output media in the several application domains of image processing, pattern recognition and computer vision among which 3D medical imaging is of particular interest. …


Design,Analysis And Routing In Static Interconnection Networks., Rajib Kumar Das Dr. Jul 1996

Design,Analysis And Routing In Static Interconnection Networks., Rajib Kumar Das Dr.

Doctoral Theses

Many real-life applications such as image processing, weather forecasting, digital signal processing, etc., require large amount of computations. By distributing the task among several processors, one can appreciably reduce the computation time. To solve complex problems, several computer architectures using multiple processors have been introduced. Recent developments in IC technology have made it economically feasible to construct multiple processor systems consisting of hundreds or thousands of processors.There are two types of multiprocessor systems (PS87). One is tightly coupled, where the processors share a common clock and/or memory. The other is loosely coupled, where each processor runs independently with a local …

Employement Fluctuations In Rural India:A Statistical Analysis With Special Reference To Maharsatra., Kaushik Bhattacharya Dr. Feb 1996

Employement Fluctuations In Rural India:A Statistical Analysis With Special Reference To Maharsatra., Kaushik Bhattacharya Dr.

Doctoral Theses

This dissertation attempts to find out the nature and the extent of employment fluctuation in rural India. The dissertation is partly theoretical and partly empirical in nature. On the methodological side, it builds up a consistent analytical frame- work. Employment fluctuation is measured in terms of a new mobility measure proposed in this dissertation. The empirical work is basod on the data collected by the National Sample Survey Organisation (NSSO), Government of India, in their 38-th round survey operation. I, therefore, thank NSSO for allowing me to work with the data. The views expressod in this dissertation or the errors …
