Password Based a Generalize Robust Security System Design Using Neural Network

Among the various means of available resource protection including biometrics, password based system is most simple, user friendly, cost effective and commonly used. But this method having high sensitivity with attacks. Most of the advanced methods for authentication based on password encrypt the contents of password before storing or transmitting in physical domain. But all conventional cryptographic based encryption methods are having its own limitations, generally either in terms of complexity or in terms of efficiency. Multi-application usability of password today forcing users to have a proper memory aids. Which itself degrades the level of security. In this paper a method to exploit the artificial neural network to develop the more secure means of authentication, which is more efficient in providing the authentication, at the same time simple in design, has given. Apart from protection, a step toward perfect security has taken by adding the feature of intruder detection along with the protection system. This is possible by analysis of several logical parameters associated with the user activities. A new method of designing the security system centrally based on neural network with intrusion detection capability to handles the challenges available with present solutions, for any kind of resource has presented

Financial Innovation and Stability of Money Demand Function in Post–reform period in India

Innovation in financial sector, financial reforms and changes in the policy environment are the factors responsible for instability in the money demanded in an economy. The dawn of 1991 balance of payment crisis in India brought much needed reforms in the economy and financial sector and triggered financial innovation fueled with revolution in information technology world wide and in India. In this backdrop this paper attempts to take a meticulous look on stability of money demand in India with quarterly data for 1996–97:1–2009–10:3 period. Based on Gregory–Hansen (1996) method of co–integration estimation the analysis confirms that in contrast to most of the previous studies, money demand function in India is not stable in the post reform period.Financial Innovation, Money Demand, Co–integration with Structural Break, Stability

Characterization of stress-deformation behaviour of municipal solid waste

Several catastrophic failures have occurred during the past two decades, both in engineered as well as non-engineered landfills. In addition, there are numerous instances of significant deformations, although not failure in the sense of significant and rapid downslope mass movement, which may cause sufficient damage to buried gas and leachate collection infrastructure. One such instance was observed in 1999 near the toe of a 75 m high 4H:1V slope at the Brock West Landfill in Ontario, Canada. Significant distortion of gas collection laterals was observed at this site. The present research is an in-depth study intended to examine deformation in landfills based on a detailed study of the mechanical properties of municipal solid waste. Four research objectives were defined based on identified shortcomings and knowledge gaps in the existing literature pertaining to mechanical properties of MSW viz; (a) to develop a method for obtaining intact samples of MSW and to examine the significance of using intact and recompacted samples in characterizing the stress-deformation behaviour of MSW; (b) to characterize MSW shear strength and Young’s modulus of elasticity from interpretation of triaxial test results and to determine the parameters of a non-linear elastic constitutive model as applied to MSW; (c) to measure the evolution of compressibility behaviour of MSW with degradation and verify the mechanism of secondary compression in waste; (d) to develop a simple design chart for predicting lateral deformations in landfills. A comprehensive research program was carried out to address various research objectives - field monitoring of deformations at the Brock West site; triaxial compression tests on large intact and recompacted samples of waste; simulating waste degradation in a large laboratory compression cell; analyzing stress-strain data from various published studies and a numerical modelling study. Interpretation of the effective stress paths followed during shearing in triaxial compression tests suggested that while recompacted samples may be sufficient to characterize shear strength parameters for use in stability analysis of landfill slopes, there might be a benefit in obtaining intact samples to evaluate the deformation characteristics of MSW. A hyperbolic model is proposed to describe the stress-deformation response of waste. The required parameters for this model were determined from evaluation of the results of numerous triaxial tests, both from this study and from the published literature. Observations from the long-term degradation test suggested that degradation has a significant effect on the compressibility of waste and further verifies the mechanism of secondary compression in waste. The coefficient of at-rest lateral pressure was observed to maintain an essentially constant value during combined compression and degradation.The results obtained from the experimental work were combined with the findings of a stochastic numerical modelling study and a statistical evaluation of published data and used to propose a simple design chart for estimating the maximum lateral displacement in a landfill slope. The design chart was developed using results of a finite element parametric study in which the behaviour of the municipal solid waste was modeled using a non-linear elastic hyperbolic model. The design chart incorporates nonlinear variation in unit weight as well as Young’s modulus with depth. The predictions from the design chart were compared with the results of field monitoring of lateral displacement in the instrumented slope at the Brock West landfill and were found to be in good agreement

A planning perspective on Hydropower Development in the Indian Himalayan Region

The Indian Power Sector(IPS) is under gradual transition from over-reliant fossil fuel (62%) to Sustainable Energy Source(SES), primarily to achieve targets of SDGs and the Paris Agreement to base 40% of the total power generation capacity on non-fossil fuel resources by 2030. In this context, the solar power generation is on the fast-track whereas, hydropower development is lagging behind due to various reasons causing time and cost escalation, hence the sustainability of IPS in terms of flexibility and reliability in integration with other Renewable Energy Source will remain a challenge. With this concern, the focus of this study is to (i) analyze and prioritize the hydropower potential (HPP) in the Indian Himalayan Region, (ii) identify the prime constraints in the way of hydropower development and (iii) discuss the way-forward for sustainable planning of hydropower development whilst appropriately managing time & cost over-runs including socio-environmental concerns. The methodology involves literature review and analysis of secondary data about IPS, hydropower resources and project-specific risks prevalent in ongoing HEPs in India. The result shows that the Indian Himalayan Region has enough (73%) balance HPP in 12 different States; sustainable harnessing of which requiresproper addressing of the prime constraints viz., multiple public consultations in clearance process, litigations, high investment, socio-political and contractual issues, mainly through procedural reforms by the State Governments which have constitutional right over land and water in the federal structure of India. The finding of study will be useful for planning process of entrepreneurs, investors and policy makers in the direction to achieve the target of SES beyond India’s Nationally Determined Contribution

Effect of Viscous Dissipation on Double Stratified MHD Free Convection in Micropolar Fluid Flow in Porous Media with Chemical Reaction, Heat Generation and Ohmic Heating

This present paper deals with the study of heat and mass transfer characteristics of the free convection on a vertical plate in porous media with variable wall temperature and concentration in a doubly stratified and viscous dissipating micropolar fluid in presence of chemical reaction, heat generation and Ohmic heating. A uniform magnetic field is applied normal to the plate. The governing non-linear partial differential equations are transformed into a system of non-linear ordinary differential equations using similarity transformations and then solved numerically using the Runge-Kutta-Fehlberg method with shooting technique. Effects of viscous dissipation on non-dimensional velocity, microrotation, temperature and concentration are presented graphically. An increase in Eckert number (which is measure of viscous dissipation) increases the velocity, temperature and microrotation, but decreases the concentration. Keywords: Chemical reaction, Double stratification, Free convection, MHD, Micropolar fluids, Porous media, Heat generation, Ohmic heating.   MATHEMATICS SUBJECT CLASSIFICATION: 76A05; 76E06; 76S05; 80A20

(R1507) Mathematical Modeling and Analysis of Seqiahr Model: Impact of Quarantine and Isolation on COVID-19

At the moment in time, an outbreak of COVID-19 is transmitting on from human to human. Different parts have different quality of life (e.g., India compared to Russia), which implies the impact varies in each part of the world. Although clinical vaccines are available to cure, the question is how to minimize the spread without considering the vaccine. In this paper, via a mathematical model, the transmission dynamics of novel coronavirus with quarantine and isolation facilities have been proposed. The examination of the proposed model is set in motion with the boundedness and positivity of the solution, sole disease-free equilibrium, and local stability. Then, the condition for the existence of sole endemic equilibrium and its local stability has established. In addition, the global stability of the endemic equilibrium for a special case has been investigated. Further, it has shown that the system undergoes a transcritical bifurcation. A threshold analysis has also performed to examine the effect of quarantine on transmission dynamics. Lastly, numerical simulations are giving hand support to theoretical results

(R2020) Dynamical Study and Optimal Harvesting of a Two-species Amensalism Model Incorporating Nonlinear Harvesting

This study proposes a two-species amensalism model with a cover to protect the first species from the second species, with the assumption that the growth of the second species is governed by nonlinear harvesting. Analytical and numerical analyses have both been done on this suggested ecological model. Boundedness and positivity of the solutions of the model are examined. The existence of feasible equilibrium points and their local stability have been discussed. In addition, the parametric conditions under which the proposed system is globally stable have been determined. It has also been shown, using the Sotomayor theorem, that under certain parametric conditions, the suggested model exhibits a saddle-node bifurcation. The parametric conditions for the existence of the bionomic equilibrium point have been obtained. The optimal harvesting strategy has been investigated utilizing the Pontryagins Maximum Principle. The potential phase portrait diagrams have been provided to corroborate the acquired findings
