Some new architectures for fuzzy logic processing
Fuzzy Logic has gained immense popularity in the last decade for use in several scientific and industrial applications. In this context, a substantial role is played by the computational structures used to perform fuzzy ... -
Adaptive algorithms for admission control of elastic sessions in the internet
In the Internet, the majority of the traffic is elastic, and is characterized by the fact that such traffic can withstand loose bounds on performance guarantees. It is a well-understood fact, however, that once the performance ... -
Performance analysis and optimization of scheduling in high speed input queuing cell switches
It is well known that the phenomenon of Head-of-the-Line (HOL) blocking limits the maximum achievable throughput of a pure Input Queuing cell switch (in which there is only one queue at each input that buffers all the cells ... -
Alternative interleaving schemes for interleaved orthogonal frequency division multiplexing
Interleaved OFDM was proposed as an effective solution for improving code rate over slowly varying channels, without affecting the Peak-Average Power Ratio. The system was proposed with a particular interleaving scheme. In ... -
Computer recognition of hand printed characters: an automated approach to the design of recognizers
Computer Recognition of Handprinted Characters is a well-established field of research, active for over three decades. Despite extensive work and numerous publications, the ultimate goal of developing a recognizer with ... -
Logic minimization algorithms for VLSI applications
The extensive use of large scale integration (LSI) and very large scale integration (VLSI) chips in the present day digital systems has evinced keen interest in the design of LSI and VLSI circuits. The design methodology ... -
A token ring local area network for small systems application
This research work deals with a new design/ and study of a token ring local area network (LAN) for small systems application like microcomputer network. The salient features of the work carried out are as follows: “ ... -
Membership algorithms for dependencies in relatinal databases
In relational database theory, a class of dependencies that includes functional dependencies (FDs), multivalued dependencies (MVDs), and join dependencies (JDs) has been found to play an important role in the process of ... -
Discrete electron fluctuations in van der Waals heterojunction
Two-dimensional (2D) materials, including transition metal dichalcogenides (TMDs) and graphene have emerged as promising candidates for next-generation nanoelectronic devices due to their atomically thin geometry. This low ... -
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 ...
