 Abstract

tubesheet in pressure vessel use to filter the natural gas during mining process for many petroleum industrial applications. During this process the natural gas contains many contaminating elements with sulphur as main ingredient, which can combines with sand or other carbon elements to create harmful effects of particulate impurities like slogging, clogging, fouling on the surface of the tubesheet. These impurities creates chemical reaction with tubesheet surface material which are normally made up of steel or ceramics. During working condition, the layer of clog is deposited on the filter tubes sheet surface and tubes. This clog layer creates increase in pressure inside the vessel. Once this pressure level exceeds the acceptable value, the filter tube sheet are cleaned either weekly or monthly basis. But this cleaning process needs to stop the entire plant working till the end of complete removal of clog, this creates reduction in efficiency parameters in terms of cost. In the present work design of pressure vessel filter tubesheet is performed on the basis of working conditions. Further it has been modified as per the corrections and suggestions given by end user. Number of holes for filtration and its pattern have been calculated on basis of modified design to get effective filtration with maximum efficiency. Another solution in terms of replacing filter unit has been proposed with which is divided into two sections and after every 4 to 5 seconds other section of tubesheet receives a back pressure of one seconds and washes out the other part of filter tubes. This modification in cleaning process gives efficient results without shutting down the plant production. Since it is a regular cycle so its needs to be shut down the plant once a year for full clean-up. This modification in working cycle creates cycling loadings on the tubesheet i.e. reverse pressure for cleaning and forwards pressure for working of pressure vessel. This compressive and tensile forces creates fatigue on the tubesheet and reduction in its fatigue strength. Therefore this tubesheet needs to analyse with modified concept for reduction in stresses and improved fatigue life. Dynamic analysis has been performed to evaluate fatigue life with modified thickness with dense meshing to get effective solution with respect to change in thickness of tubesheet.

 Abstract

Steganography is the process of concealing secret messages in color covering images, steganography hides the existence of the message within the color image so that it cannot be seen by natural eyes. Steganography is a crucial process that can be utilized in multiple life applications. This paper will introduce some methods used for data steganography. These methods will be implemented and results based on the experiment will be gained. A great method of steganography will be utilized, it will be shown how this method will bring efficiency, capacity, security, and covering image quality. To give more security for the biomedical reports for the patient privacy for the patient highly confidently patient image reports can be placed in databases digitally. If unknown persons like hospital staff, relatives, and third parties like intruders trying to see the report it has in the form of a hidden state in another image. The patient detail like Patient Name, Age, Gender, referred by a doctor, referred to, Date, Medicine Names have been converted into any form of steganography. Then, encrypt those images by using the proposed steganography algorithm and placed them in the database.

 Abstract

A study analysis to determine the effects of operational stress on employee performance during the covid-19 epidemic. The project report is about the level of staff pressure that is an integral part of any organization, which is considered a necessary asset of the company. The main concern of respondents is safety and security in the covid-19 virus and they take all precautionary measures while on duty a sample size of 120 is taken for the purpose of analyzing the project using a simple sample. In the complete sample the majority of respondents are among all respondent staff satisfied with the physical and mental condition of the respondents who are satisfied with the physical and psychological working conditions of the organization.

 Abstract

Ultra Performance Liquid Chromatography (UPLC) takes the advantage of technological strides made in particle chemistry performance, system optimization, detector design and data processing and control. Using sub 2 mm particles and mobile phases at higher linear velocities and instrumentation that operates at higher pressures than those used in HPLC, dramatic increases in resolution, sensitivity and speed of analysis can be obtained. This new category of analytical separation science retains the practicality and principles of HPLC while creating a step function improvement in chromatographic performance. This review introduces the theory of UPLC and summarizes some of the most recent work in the field

 Abstract

In the Modern Era of fast moving technology humans developed applications like Personal Voice Assistant having the ability to interact with the surroundings by human interaction i.e HUMAN VOICE. Web Engineering has become a major delivery platform for a variety of complex and sophisticated enterprise applications in several domains. Education gives us knowledge of the world around us and changes it into something better and also develops in us a perspective of looking at life so we had set the scope to Institute level. So we are going to develop a Web Engineering application for the Education domain wherein it will be used by the role of Professors and students. In this proposed system, the Professor's voice assistant would be able to set and extend timelines of assignments or any schedule exam. Professors can also set their respective lectures timetable so that they can get reminders whenever the lecture is scheduled. At the Institute level it will be integrated with the features like students curricular tracking which will help the professors to analyse and track their curriculum growth. The students can set alerts for their exams or for any required notes,view the Timetable from a web page and extract the details related to Exams or any respective Subject using voice Recognition by using the ASP.Net Framework and AI. The Principal of Institute or any Higher Authority person can View the details of Professors via Voice Commands. We train the module to accept the voice commands and perform the functions accordingly by enhancing some features introduced by Cortana.
