Objectives: The online traffic surge rates have rapid growth in the recent years. The rate has gone high, making the service providers unable to provide the quality of service they assure. The surging cannot be controlled and the only solution lays on the other side, so the providers are forced to choose another methodology of delivering the service in quality. Methods/ Statistical Analysis: In this paper the process of implementing an alternative is proposed. The work is concentrated on creating a Raspberry Pi to work as a transparent cache server with the smart phones enacting as the client. Findings: The issues of streaming videos are ending up being more critical to customers as they pay for over-the-top substance yet, still experience exceptionally less than impressive streams. To get a quick response and decrease access latency, utilizing a cache memory is prudent. A transparent proxy cache server wipes out numerous disadvantage of ordinary methodology. Transparent proxy cache server can be conveyed in two levels, one at switch level and another at router level. The attention is primarily on http result reserve which stores URLs of Previously accessed query results. These caches might be deployed in various machines, acting about as a proxy cache cluster, or exists together in the same machine. In this proposed framework we introduce a straight forward web store middle server, to upgrade the execution. The only work to be done regarding the promise of content availability is continuous monitoring of the cache. Application/Improvement: The proposed methodology can serve the right speed of content delivery by facilitating access of data from the cache while giving no hint that the data has been retrieved through IP-spoofing of the server which here is a small sized computer the Raspberry Pi.Keywords

Objectives: This study aims at designing an easy and a secured way of remote server based data logging using a data acquisition mechanism and HFS (http File Server) software. Methods/Statistical Analysis: Lab VIEW based remote data monitoring and controlling system is designed so as to view and analyze the fidelity of the data. This mechanism proves to be a secured data logger providing an increased access to the users in the loop, along with time stampings and many other additional features. A real time nonlinear process system was considered as a bench mark system for the purpose of logging the level data of it remotely. The Dual Spherical Tank Liquid Level System (DSTLLS) has been chosen and its continuously varying liquid levels are recorded and monitored remotely over the LAN, using remote Master-Slave architecture and File Transfer Server. Findings: It was found that these methods of the data logging prove to be faster and cheaper when compared to the existing methods. Classical algorithmic approach for the data transfer is being applied to facilitate the data logging process. Application/Improvements: There is scope of performing experiments on the data transfer mechanisms using different algorithms and analyzing their performance and efficiency in data logging process.Keywords

Objectives: The process industries have always been in search of innovative ways of data logging mechanisms, for they happen to execute complicated flow mechanisms on a long span of time uninterruptedly. Data loggers in existence have contributed to a greater extent as assisting technology to store and monitor the data and also in rugged measurement environment.

Background/Objectives: PID controllers are one of the first solutions often considered in the control of process industries. It has always been very difficult to treat the level anomalies n the real time processes. Particularly the non linear systems and processes have been a challenge in relation with their dynamics and flow properties. Methods/Statistical analysis: Dual Spherical Tank Liquid Level System (DSTLLS) has the characteristics of nonlinearity due to the dynamic behaviour and area of cross section of tank. One of the major problems in process industries is to control of liquid level for Second Order System Plus Delay (SOSPD) system because the presence of time delay in the system can lead to destabilization of the system. This simulation aims at portraying the performance of the designed Internal Model Control (IMC) PID Controller. Using the black box modelling technique the SOSPD is mathematically modelled experimentally, assuming the system to be a Single Input Single Output (SISO) model. Findings: The aim of this paper is to design a PID controller using IMC tuning method for a (DSTLLS) whose modelling has been done in real time. This simulation briefly explains about stabilizing problem for SOSPD system using an IMC PID controller. The designed controller performance is analysed in terms of performance indices like Integral Squared Error (ISE) and Integral Absolute Error (IAE) and time domain specifications like Rise time, Settling time and Peak time. Conclusion: The validation of the performance of the designed controller is performed under MATLAB environment. There can different controllers which can be also experimented on the same mathematical model for different configurations of the system, namely MISO and MIMO.Keywords
