Evolution of NICNET as an incrementally intelligent network

The evolution of NICNET, the Computer-Communication network of the National Informatics Centre, is so oriented that integration and globalization are progessively implemented utilizing the latest cost-effective technologies available In the international market. With the choice of SSMA/CDMA based VSAT technology utilizing a C-band transponder, during the nucleating stage of NICNET, the top 500 cities and towns in India have been linked apart from more than 100 sites of mega projects and economically important locations. In the next step, high speed SCPC based VSATs with two-way as well as data broadcast capabilities utilizing a Ku-band transpoder is enabling the realisation of the NICNET InfoHighway linking metropolises and big cities as an overlay network over tile low speed NICNET. Dedicated high speed external gateways provide initial infrastructure for globalization of NICNET. In the next phase, it is planned to introduce software based information networking architecture on NICNET for which the concept of structure-function matrix based incrementally intelligent network design is proposed in this paper. As the demand for sophisticated services like CUGs, virtual private network Service, universal personal communications, mobile communication and multimedia services increase, NICNET will be required to respond with more flexible access, intelligent management and versatile charging regimes than what is possible currently, all within the frame-work of an open system architecture. Imperatives of globalization and service creation will be rendered incrementally intelligent utilising an approach based on intelligent hypermedia with imbedded expert system for realising intelligent navigation and integration. The same AI approach is determined to be advantageous for intelligent integration of traffic and facility with adaptive flexible routing. The design of NICNET as an intelligent global network providing a versatile local infrastructure with multiple gateway hooks to a global network employing low or medium earth orbiting satellite constellation, is identified as a desirable long term goal

Design of Participatory Virtual Reality System for visualizing an intelligent adaptive cyberspace

The concept of 'Virtual Intelligence' is proposed as an intelligent adaptive interaction between the simulated 3-D dynamic environment and the 3-D dynamic virtual image of the participant in the cyberspace created by a virtual reality system. A system design for such interaction is realised utilising only a stereoscopic optical head-mounted LCD display with an ultrasonic head tracker, a pair of gesture-controlled fibre optic gloves and, a speech recogni(ion and synthesiser device, which are all connected to a Pentium computer. A 3-D dynamic environment is created by physically-based modelling and rendering in real-time and modification of existing object description files by afractals-based Morph software. It is supported by an extensive library of audio and video functions, and functions characterising the dynamics of various objects. The multimedia database files so created are retrieved or manipulated by intelligent hypermedia navigation and intelligent integration with existing information. Speech commands control the dynamics of the environment and the corresponding multimedia databases. The concept of a virtual camera developed by ZeIter as well as Thalmann and Thalmann, as automated by Noma and Okada, can be applied for dynamically relating the orientation and actions of the virtual image of the participant with respect to the simulated environment. Utilising the fibre optic gloves, gesture-based commands are given by the participant for controlling his 3-D virtual image using a gesture language. Optimal estimation methods and dataflow techniques enable synchronisation between the commands of the participant expressed through the gesture language and his 3-D dynamic virtual image. Utilising a framework, developed earlier by the author, for adaptive computational control of distribute multimedia systems, the data access required for the environment as well as the virtual image of the participant can be endowed with adaptive capability

Stochastic vectorial flow graph analysis of meteorological cause-effect relationships for drought prediction

Advocating the view that the drought prediction models which neglect the complex feedbeck mechanisms in the cause effect relationships between variables of meteorological, hydrological and topographic origin may give faulty predictions, a system theoretic method is proposed for taking into consideration certain dominant cause-effect reIationships. The method is based on the concept of stochastic vectorial flow graph developed earlier by the author which is used in conjunction with a characterization of the interacting stochastic variables by cross-autocorrelation. A comprehensive feedback system of importent interacting Eeteorological variables is proposed for drought prediction along with an approach for computer aided analysis of such a system

Axiomatic derivation of Maxwell's equations

The derivation of Maxwell's equations commencing with Coulomb's law can be carried out in several ways by extending the work of Page. However, their derivation without assuming any experimental results of electromaglletics like Coulomb's law has not so far been carried out. This communication gives an axiomatic derivation of Maxwell's equations assuming only the conservation of charge, special relativity with the associated structure of space and a reIation connecting electric and magnetic field intensities

Amplification factor of triodes with elliptic grids having support rods

A capacitance equivalence method to determine the amplification factor of triodes with irregular geometry was proposed by O'Neill. This method does not intrinsically take into its purview the presence of support rods of appreciable radius. In a previous communication, the author derived the equicapacitance structure for elliptic grids using a method based on O'Neill's principle. In this paper the analysis given there at is supplemented with a criteria for obtaining an equivalent radius for the support rods, which would produce nearly the same screening fraction, if the position of these rods is reckoned at the circumference of the equivalent circular grid. The amplification factor formula is consequential

Some Coincidence Point Theorems and an Application to Integral Equation in Partially Ordered Metric Spaces

In ordered metric space, the results on coincidence point of the mappings satisfying generalized rational contractions are investigated. Also discussed the integral contractions of the mappings in the same context to obtain the coincidence points. Two numerical examples are presented to justify the results obtained. Apart from in view of an application, the existence and the unique solution of an integral equation is discussed

Some threshold results and global stability of a host-mortal commensal ecological model with immigrated host species

The paper consists some threshold results on a Mathematical Model of a Host-Mortal Commensal Ecological Model with host is being harvested (Immigrated) at a constant rate by the identification of threshold regions through illustrations. Further, the global stability of this model with limited resources is established by Liapunov’s stability criteria. It is elicited by constructing a suitable Liapunov’s function for evaluating the global stability of the model in the case of co-existence equilibrium state. A pair of non-linear system of ordinary differential equations characterizes the model and the two equilibrium points are identified. Some threshold results are derived to establish the stability of the coexistent equilibrium state

Graph theoretic extension of the Matrix model of an R & D organization

In this paper the matrix model of an R&D organization developed by Dean [1] has been extended to organizations with mixed global objectives based on a graph-theoretic formulation. The extended model can be applied to problems like the maximization of R&D outputs of a number of organizations at the level of either a corporation or a country such that a specified growth in the overall research competence of the entire corporation or the country is maintained
