Approximate decoding over tail-biting trellises
This thesis proposes and implements soft-decision decoding algorithms on tail-biting trellises. For linear block codes, tail-biting trellises are interesting from a soft-decision decoding view-point, because of their reduced ... -
Scaling the performance of web servers using a greedy data buffering and caching strategy
Pervasive use of the web has placed extreme performance demands on its key architectural elements of which the web server is the most critical. A web server is a highly I/O intensive application, and I/O data handling ... -
Fault-tolerant distributed algorithms for reconfiguration of rings using management tokens
In this thesis, we propose two algorithms using slightly different approaches to detect failures in a ring, and to reconfigure the ring using a combination of multithreading and management tokens which circulate around the ... -
A complier writing system based on affix grammars
Compiler Generators have become well-established tools in the production of a compiler. In general, a compiler generator uses a specification of a programming language at an abstract level as input and outputs the code for ... -
Evaluating cache performance under multiprogrammed workloads
Computer system performance is critically dependent on cache performance. Cache effectiveness is determined by factors such as program locality of reference and cache organization. Different approaches to cache performance ... -
Sequential Decision Making with Risk, Offline Data and External Influence: Bandits and Reinforcement Learning
Reinforcement Learning (RL) serves as a foundational framework for addressing sequential decision-making problems under uncertainty. In recent years, extensive research in this domain has led to significant advancements ... -
Constrained virtual path routing algorithms in packet networks
We presented a new algorithm for on-line routing of Virtual Paths in a packet network. The main application of the algorithm is in explicit routing o f LSPs in MPLS networks. We modeled the routing problem as a mixed ... -
Wavelength routing in All-Optical networks using full, limited and no wavelength conversion
We study the effect of full, limited and no wavelength conversion on the blocking performance of the all-optical networks. We first formulate an exact model for linear tree networks for the case of full and no wavelength ... -
Call admission control for deterministic traffic in speed networks
Future high speed network, such as Broadband ISDN, will be required to carry the traffic generated by a wide range of services. These services will have very diverse traffic flow characteristics and performance requirements. ... -
Optimal control for queue length fairness in dual bus networks
Advances in optical fibre transmission have created interest in a class of multiple access local and metropolitan area networks called unidirectional bus networks. In the absence of medium access control, the nodes closer ... -
Programmable nonlinear ADCS -some new techniques
New Program mable Successive Approximation NADCs In this class of NADCs, the main emphasis has been to achieve digital programmability by using optimal-sized ROM, or PLS in the successive approximation loop while at the ... -
Wave from mapped multiplexing: an alternative methodology for multiplexing plesiochronous channels.
From the above analysis, it is evident that implementing Weighted Mean Method (WMM) using a fixed point of reconstruction introduces a bias of the form (x?Tg2)Tg2(x - \frac{T_g}{2})^{\frac{T_g}{2}}(x?2Tg??)2Tg?? in the ... -
Design and performance studies on bus-based multi microcomputer systems
(1) Highlight the key attributes of the design space at the processor memory subsystem level of bus-based multimicro-computer systems; and suggest memory placement as well as bus-allocation procedures, which can result in ... -
A simplified approach for wordlength reduction of control memory of microprogrammed processors
Since its inception by Wilkes in 1951, microprogramming has made considerable progress in both techniques and applications. Much of this progress has been made possible by significant improvements in memory technology. ... -
Unified approach for analyzing persistent, non-persistent and ON-OFF TCP sessions with RED control and exogenous traffic
We first look at a router with multiple TCP and UDP connections. The UDP stream has pre-emptive resume or non pre-emptive priority over the TCP connections. The UDP stream is modeled as a Markov modulated Poisson process ... -
Localization methods for correlated spatially distributed sources
Modeling of sources as point in nature is a very idealistic modeling in array processing. There have been a number of distributed source models proposed in the literature. This work is based on one of these models. It tries ... -
Studies on methods of reducing some cost parameters in microprogrammed digital computers and distributed processing systems
The concept of microprogramming is frequently employed in designing the control units of modern digital computers and microprocessors. In a microprogrammed digital computer, the size of control memory depends upon the width ... -
Signal Processing Algorithms for Target Parameter Estimation in a Dual-Function Radar Communication System
In next-generation technologies, the demand for higher performance in fields such as radar and communications is driving the use of higher frequencies, leading to spectrum congestion. A promising solution to this challenge ... -
A framework for timing analysis of event-driven applications
Event-driven applications, particularly those based on the publish–subscribe communication model are widely adopted to build responsive and decoupled applications in domains such as robotics, the Internet of Things ... -
Character Recognition Using Optical Correlation
A study of effect of rotation and lateral displacement on the correlation outputs when two characters are correlated optically (Taking numerals as characters) has been carried out. Thus, the feasibility of optical correlation ...
