In this work, we study the Tsallis holographic dark energy with Hubble horizon as IR cut-off with the energy density given by rho? = 3 beta 2M2pH-2 delta+4 in f(R, T) theory. Considering a flat FRW Universe, we obtain the equation of state parameter guided by f(R, T) gravity. We investigate the corre-spondence between the tachyon, Dirac-Born-Infeld-essence, and the phantom scalar field models with the Tsallis holographic dark energy in the context of f(R, T) gravity. By equating the equation of state parameter in f(R, T) theory and rho? with scalar field models, we reconstruct potentials and dynamics for these models for different Tsallis parameter delta. By analysis, we can show that for Tsallis holographic tachyon, Dirac-Born-Infeld-essence, and the phantom models, if the related model parameters fulfill some constraints, the accelerated expansion can be obtained in the framework of f(R, T) gravity.

This paper describes & improvise Call Blocking Probability calculations , considering fixed number of channels & traffic generating sources in typical UMTS cell. More specifically , for uplink directions, a Loss Model (EnMLM) has been proposed by integrating it with local blocking aspects . As such the incoming call has to compete for the resources for it’s successful admission to a UMTS cell . In principle such admission of incoming call is controlled by availability of required channels . To analyze the system, an aggregate one-dimensional Markov chain has been formulated , and based on it, the system state probabilities has been determined by an efficient recurrent formula. Subsequently, the call blocking probabilities has been calculated in the uplink direction. By way of approach, the proposed model is approximate, however, its accuracy is found to be quite satisfactory. The evaluation of results has been done via simulation and results substantiate the findings of the basic call blocking probability calculations. Additionally, this model has much wider scope and it performs better than the existing model which assumes infinite number of traffic sources in the cell.

In this paper we check the performance of a GSM cellular communication system by using FDMA –TDMA system . In the present paper we evaluate the performance of the blocking probability, spectral efficiency and the bit error rate by using the a specific model. By using this we try to improve Rician and lognormal. Keywords— GSM, Multipath effect, TDMA, North-American system.

In the recent day's web applications usage is increasing by banking, financial institutes and health or hospital management systems such as online or net banking and mobile banking, e-commerce applications, news feeds, inpatient and outpatient information etc. All these online applications require support for security properties like authentication, authorization, data confidentiality, and sensitive information leakage. The most widely accepted common method of authentication for an online application is to use a combination of alphanumeric with special characters usernames and passwords. Net or online applications should support a strong password (such as a combination of Alphanumeric with special characters). In the past recent studies reveal that the end users today have on an average approximately 10 to 15 passwords to protect their online accounts to do their actual transactions. In general, a common web (internet) user having one password may be easy to remember, but controlling many passwords for different web or internet applications is time-consuming task and a security threat. Usually passwords are not secured at all as they can be guessable or somebody (a malicious user) can be stolen. To overcome this, passwords need to be stronger authentication solutions.

The number and the importance of Rich Internet Applications (RIA) have increased rapidly over the last years. At the same time, the quantity and impact of security vulnerabilities in such rich internet applications (RIA) have increasing as well. Since manual code reviews are time consuming, error prone and costly and it need skilled developers or programmers to review the manual source code review, the need for automated solutions has become evident. In this paper, we address the problem of application security vulnerable detection in Adobe Flex (Rich Internet Applications) platform in web 2.0 applications by means of static source code analysis. To this end, we present precise analysis targeted at the unique reference semantics commonly found in RIA based web applications or widgets (small applications which will run on fly i.e. drag and drop) developed in Adobe Flex Framework or Action Script 3.0. Moreover, we enhance the quality and quantity of the generated vulnerability reports.

In Today's tautness life people are facing multiple physical, physiological, psychological problems. They have no time to visit doctors again and again. Sometimes there is a situation when a patient requires treatment on the spot. To solve these problems we require a technique which collects all the data about people's disease in spaces ranging from personal to urban. Wireless sensor network (WSN) technologies are considered one of the key research areas in computer science and the healthcare application industries for improving the quality of life. The purpose of this paper is to provide a snapshot of current developments and future direction of research on wearable and implantable body area network systems for continuous monitoring of patients. In this paper, medical sensors were used to collect physiological data from patients and transmit it to Intelligent Personal digital Assistant (IPDA). This paper explains the important role of body sensor networks in medicine to minimize the need for caregivers and help the chronically ill and elderly people live an independent life, besides providing people with quality care. Although offering significant benefits, the field of wearable and implantable body sensor networks still faces major challenges and open research problems which are investigated and covered, along with some proposed solutions, in this paper.

These days, due to the heavy traffic, it is very difficult for drivers in big cities to find an easy and efficient route to a selected destination. Thus, route guidance has become a very important problem for drivers. As a result, car navigation systems are commonly installed in new vehicles. These systems are capable of performing some of the tasks traditionally performed by driver, such as reading the map and determining the best route to the destination. The process of finding optimum path from one point to another is called routing. The suggested algorithm is improved version of dijkstra algorithm that can search for the shortest path at a restricted search space. The search space is restricted by the use of a rectangle or a static and dynamic hexagon. These methods can improve run time and usaged memory because the visited nodes and edges are limited. In order to show the effectiveness of the proposed algorithm, it is tested on the city map of Gurgaon. Following, this result is compared to the result obtained with dijkstra's algorithm.

In this paper, we develop a mathematical model of sprinting in which anaerobic metabolism is included. This model is simplified by considering the broad changes of energy level and the cyclic variation associated with the strike pattern. We consider the effect of the centre of mass to the overall energy balance along with force of resistance during initial motion of body. Results are obtained for the model from an event of a sprint championship. These computed results closely predict the overall average performance of the participants over the course of entire race.

Due to the properties of tumor cell, the tumor establishes itself in the organ and grows there, so there is a competition between the tumor cells and host cell (normal cells) for nutrients. Evidences show that high dietary phosphorus increases the rate of protein synthesis and thus the cell number. So, other than oxygen, sulfur, the important element that both tumor cells and normal cells need is phosphorus. Hence, the proliferation and growth rate of both tumor cells and healthy cells depends on the content of phosphorus available to them. So, the mathematical model with time delay is prepared in which the growth rate of tumor cells and normal cells are function of phosphorus with their restrictions. And by applying suitable implications on the model and studying the simulations we will come to know its effects on tumor growth.

The flow in an elastico-viscous fluid between two co-axial infinite rotating porous discs is considered for high cross flow Reynolds number. The discs are rotating with different angular velocity and the injection rate of the fluid at one disc is different from the suction rate of other disc. The effect of suction parameters on the velocity components have been investigated numerically and solved by iterative methods/finite difference methods and depicted graphically. This study has immense practical utility especially when the fluid is non-Newtonian. The results are applicable in the chemical industry using fluids of higher Reynolds numbers.
