In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance
In recent years, self-compacting concrete (SCC) has gained wide use for placement in congested reinforced concrete structures with difficult casting conditions. For such applications, the fresh concrete must possess high fluidity and good cohesiveness. In this present study, the effect of replacing the cement, fine aggregate and coarse aggregate by constant replacement of silica fume, Manufactured sand (JSW) replacement of 0%, 10%, 20%, 30%, 40% and light weight aggregate replacement of 10%, 15%, for internal curing respectively and their combinations of various proportions on the properties of different mixes of M40 grade has been compared with normal self compacting concrete by conventional curing method. In this study fresh property and hardened properties of the different mixes of concrete were determined. From the present study the test result showed that for fresh concrete all the mixes satisfies the EFNORC standard values.
Cloud computing is the apt technology for the decade. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. While Cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. On the similar terms, we have chosen to make use of a combination of authentication technique and key exchange algorithm blended with an encryption algorithm. In this project, we have proposed to make use of 3DES algorithm which is a well-known symmetric cryptosystem and is widely used for secure data transmission, along with that we will blend it with Random Key Generator and Graphical Password to add an extra security measure. This proposed architecture of three way mechanism and the use of symmetric method of encryption make it tough for hackers to crack the security system, thereby protecting data stored in cloud.
This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.
Gray level Slicing is to highlight a specific range of gray values. Power Adaptation methods are presented for gray level slicing approaches. Power Adaptation methods aims in optimization of the resulting bit error rate by gray level slicing without preserving background and gray level slicing with background. This paper gives us an achievable increase in the proposed method rather than the conventional method with a better quality and the bit error rate is also optimized in proposed method rather than the former method with acceptable quality.

Video conferencing is executed connected with video conferencing. Many people refer to it as videoconferencing. This kind of techniques is among the brand-new efficient strategies to transmission today specifically all over region and continents. Video conferencing consists of connection involving two or more teams of individuals in a given setting or even between numerous places along with internet sites from different periods. In general, its major role is actually interaction in between men and women regardless of the distance.
