Application of Neuro-Fuzzy system to solve Traveling Salesman Problem

This paper presents the application of adaptive neuro-fuzzy inference system (ANFIS) in solving the traveling salesman problem. Takagi-Sugeno-Kang neuro-fuzzy architecture model is used for this purpose. TSP, although, simple to describ

The reduction of stress concentration in a uni-axially loaded infinite width rectangular isotropic/orthotropic plate with central circular hole by coaxial auxiliary holes

A comprehensive plane stress finite element study is made for reduction of stress concentration factor (SCF) in a uni-axially loaded infinite width rectangular isotropic/orthotropic plate with central circular hole. The finite element formulation was carried out by the analysis section of the package ANSYS. With the help of present work, stress concentration can be reduced up to 24.4 % in an isotropic and 31 % in an orthotropic plate by introducing four coaxial auxiliary holes on either side of main hole. The study reveals that the introduction of these holes helps to smooth flow of the tensile stress past the main hole and result a reduction in stress concentration factor. With such reduction in maximum stress levels, the improvement in fatigue life of a component can be significant

A Study on the Challenges Regarding Conservation of Water Resources in Rajasthan

Water can not be produced but conserving water is equivalent to production of water. Rajasthan has worked on two side water conservation theories. (i) Supply side (ii) Demand side water Supply Side Water Conservation Activities;- Harvesting the available surplus rainfall runoff by Efficient use of existing resources ,Water Harvesting, Artificial Ground water recharging,Increase in use of treated water,Demand Side Water Conservation Activities;- Various interventions taken for demand side water conservations are as under Diversification in cropping pattern,Micro irrigation system,IEC activities to use water optimally

Emerging and re-emerging viral infections in India

The number of outbreaks have  progressively increased since many years in India. In this era of globalization and rapid international travel, any infectious disease in one country can become a potential threat to the entire globe. Outbreaks of Nipah, Zika, Crimean- Congo Haemorrhagic Fever and Kyasanur Forest Disease and have been reported since a decade and now we are facing COVID 19 pandemic. One of the challenges in the prevention of these outbreaks is that as the cases decrease, the felt need declines, the public demand decreases and the mitigation responses get overshadowed by the need of emergency responses elsewhere. The One Health approach is a movement to promote alliance between medicine field, veterinary medicine and environmental sciences to upgrade the health of humans, animals, and ecosystem. The data in this article is compiled from different websites and publications of World Health Organization (WHO), Centre for Disease Control and Prevention (CDC), Integrated Disease Surveillance Programme (IDSP), grey literature and media. There is an urgent need for better surveillance and disease burden assessments in the country and to gain detailed insights into vector biology, factors of environment influencing the diseases, mapping of endemic areas, strengthen intersectoral coordination, infection control practices, and ensure use of Personal Protective Equipment’s (PPE) and availability of drugs and vaccines to handle the outbreaks in a better way

TCP I-Vegas in Mobile-IP Network

provides hosts with the ability to change their point of attachment to the network without compromising their ability to communicate. However, when TCP Vegas is used over a MIP network, its performance degrades because it may respond to a handoff by invoking its congestion control algorithm. TCP Vegas is sensitive to the change of Round-Trip Time (RTT) and it may recognize the increased RTT as a result of network congestion. This is because TCP Vegas could not differentiate whether the increased RTT is due to route change or network congestion. This paper presents a new and improved version of conventional TCP Vegas, which we named as TCP I-Vegas (where “I”, stands for Improved). Vegas performs well when compared to Reno but when sharing bandwidth with Reno its performance degrades. I-Vegas has been designed keeping in mind that whenever TCP variants like Reno has to share the bandwidth with Vegas then instead of using Vegas, if we use I-Vegas then the loss which Vegas would have to bear will not be more. We compared the performance of I-Vegas with Vegas in MIP environment using Network Simulator (NS-2). Simulation results show that I-Vegas performs better than Vegas in terms of providing better throughput and congestion window behavior. Keywords—TCP Vegas; Mobile-IP; NS-2 I

AN EMPIRICAL STUDY FOR EXPLORING CUSTOMER SATISFACTION TOWARDS DTH SERVICES USING SERVICE QUALITY DIMENSIONS - A DETAILED STUDY OF DELHI NCR

ABSTRACT Measuring the quality of a service can be a very difficult exercise. Unlike product where there are specific specifications such as length, depth, width, weight, and color etc. a service can have numerous intangible or qualitative specifications. In addition there are the expectations of the customer with regards the service, which can vary considerably based on a range of factors such as prior experience, personal needs and what other people may have told them. In the age of information technology and highly competitive business where world has become a truly global retaining current customers and attracting potential customers has no alternative. This can only be achieved by customer centric strategies and missions and filling the gap between expectations and perception of service provided by DTH operators. Thus it is important to analyze the gap in the service on regular basis and following the improvement, if any, is very important in this paper such analysis of the gap is investigated on services provided by DTH operatorsto its customers in Delhi. SERVQUAL has been used as a tool with 5 dimensions and statements for this analysis. The Gap score is a reliable indication of each of the five dimensions of service quality. Using SERVQUAL, service providers can obtain an indication of the level of quality of their service provision, and highlight areas requiring improvement. Questionnaire survey is used to work out the gap score using SERVQUAL scale and shove area have been identified on the basis of the gap score where the DTH operator should pay focused attention. The perceptions, of the DTH SERVICE QUALITY The single most researched area in services marketing to date is service quality. According to Fisk et al. (1993) early research in service quality disclosed its subjective nature, but it was not until several years later that the concept of service quality as the result of differences between actual and expected levels of service began to emerge. This implies that organizations must establish requirements and specifications; once established, the quality goal of the various function of an organization is to comply strictly with these specifications. In today's increasingly competitive environment, quality service is critical to corporate success. In the past the focus was mainly on meeting internal quality or technical standards. The focus today has shifted to qualifying customer assessments of services, and translating these measures into specific internal standards (Brown, Hitchcock and Willard, 1994) Delivering high quality service is closely linked to profits, cost saving and market share. Service quality is defined as "a global judgment or attitude relating to the overall superiority of the service" (Parasuraman, Zeithaml and Berry, 1988
