General purpose simulation tool for the performence analysisof ATM Switches
The Broadband Integrated Services Digital Network (B-ISDN) supports a wide range of audio, video, and data services within the same network. To cover the widest range of applications possible, B-ISDN should support both ... -
Some investigations on performance improvement of turbo decoders
Iterative turbo decoders have become popular in error correction because of their excellent Bit Error Rate (BER) characteristics, approaching Shannon limits. They have shown great potential in a variety of areas like ... -
Investigation on architectural elements of network processors
Increasing network speeds have placed enormous burden on the processing requirements, and the processors are expected to carry out a variety of tasks. Network Processors (NP) is the blanket name given to the processors ... -
Approach to the Analysis of Scheduling Policies for Guaranteeing Delay with Arbitrary Arrivals
Many real-tim e applications need a delay guarantee from th e network. For this scheduling algorithms are useful. Therefore, given a scheduling algorithm and a characterization of arriving traffic, it is im p o rtan t to ... -
Improving quality of speech in VoIP using time-scale modification
Voice over Internet Protocol (VoIP) is an emerging technology that enables the transport of voice over the Internet. The quality of delivered voice is a critical issue due to packet loss and end-to-end delay variations ... -
Optimal mobile assisted offloading and network price differenciation
This thesis studies two problems related to cellular resource provisioning. The first problem deals with mobile-assisted data offloading, and the second problem analyzes network partitioning for differential pricing and ... -
Modeling, Design and Control of Power-Electronic-Actuated Electromagnetic Bearings
Many practical electrical machines, turbines, and compressors operate in speeds ranging from tens of thousands of rpm to hundreds of thousands of rpm, also handling a significant amount of power. While high-speed operation ... -
Design and implementation of a high speed interconnection network for ANUPAM
The basic hardware and software features of the ANUPAM system have been described in this chapter. Communication within and outside the clusters in ANUPAM are also described. The communication bandwidth within an ANUPAM ... -
Multi-scale approaches to signal deblurring and reconstruction from zero-crossings
This thesis addresses two inverse problems in computer vision: Solving a class of ill-posed convolution equations We analyze the problem of deblurring a Gaussian-blurred signal, which belongs to the class of ill-posed ... -
On the Eikonal equation and shape from shading
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) ... -
Fractal encoding for inpainting and secure image sharing
Fractal Encoding for Inpainting and Secure Image Sharing This thesis is an investigation to explore two new applications of fractal encoding: 1) secure image sharing and 2) image inpainting. Fractal encoding is a lossy ... -
Enhanced neural networks architectures for pattern classification
The thesis deals with the problem of pattern classification for which new algorithms using three different neural network models have been proposed: (i) Recursive (ii) Feedforward; and (iii) Self-Organizing Networks. These ... -
Machine recognition of printed kannada text
Optical Character Recognition (OCR) provides a more efficient and faster solution for many real-world problems such as form readers for various application forms, bank cheque reading, and postal mail sorting. Manual operation ... -
A Stochastic dynamical system for edge detection
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 ... -
Implementing a weak form of memory consistency on a tree-based system
In this thesis, we propose and implement a weak form of memory consistency, called the Release Consistency for the Tree structure (RCT) model. This model exploits the properties of a tree network to yield a programming ... -
Feature transformation for speaker identification
The gradual automation of services and transactions that previously required human handling has led to a growing interest in biometrics, which are unique measurable traits of a human being used for automatic identity ... -
Pattern recognition techniques based on self-Organization and learning vector Quantization
Autom atic Recognition of Patterns (APR) by a machine is perhaps the most challenging problem in Artificial Intelligence. The leitmotiv for the design of such a machine comes from the human visual system which is endowed ... -
Machine recognition of printed odiya text
Automatic recognition of characters by a machine is one of the challenging problems in Artificial Intelligence. The motivation for the design of such a machine comes from the human visual system (HVS). HVS is endowed with ... -
Protocols for Highly available distributed call processing systems
In telecom applications, a key requirement of any call processing system is high availability; an order of “five nines” availability is needed. With the evolution of Next Generation Networks (NGN), the current trend in the ... -
Design and implementation of a fortran to occam parallelizing parallel translator
Dependence analysis, which is the most critical component of PPT, has been described in this chapter. In order to establish dependence relations between multiple occurrences of different types of variables such as ...
