Computational fluid dynamics is a widely used technique which is used to simulate indoor air conditions. This study includes experimental as well as numerical work using computational fluid dynamics program of a computer laboratory /with high wall mount split air conditioning system. Experimental results are compared with the numerical one to evaluate the CFD program. CO2 concentration field measurements were taken which is standard to check indoor air quality of the computer laboratory. Cooling load requirement of the laboratory is also evaluated in this study. Twelve points were considered in laboratory to take reading for temperature, humidity and CO2 concentration.CO2 concentration exceeded the permissible as well as hazardous limit set by ASHRAE standard 62.1,2013. Good agreement is achieved between the computed and measured temperature results. The experimental and numerical results showed that the model is capable of giving close results with experimental one and due to this modifying the model can give a better air temperature distribution. The simulation also showed the existence of cold spots and stagnant are in the laboratory.

Although this system provides electronic documents like books, magazines, newspapers, and other useful files that can give access for the users without any restrictions and help librarians keep track of library information. Designing a computerized library management system (LMS) that would support to evacuate the problem encountered in the manual library. The physical library has many limitations to satisfy user’s needs, and most hard copy documents are damaged after a limited time of usage. To eliminate the paperwork in the library, to reduce the high demand for the cost of books, and to avoid problems for missing files, we introduce a web-based LMS in ACCE. This will provide services for the entire citizens of the country in a different format without limitation of the period. The objectives of this research are to develop a system that can handle and manage the actions involved in the ACCE library efficiently and reliably which can be a benefit for the entire users to get access at their convenient time. To overcome the above-mentioned limitations of the physical library, we are implementing this new technology to promote digital reading habits for users and to advance the knowledge of the users in every aspect of the technology.

The experiment of underwater data communication in the laboratory is different with that in the real water environment because the physical scale is limited. In this paper, several kinds of agents are evaluated to change the coefficients of experimental water precisely. Then, seemed as criterion for the reliability of water recreation, the frequency domain characteristic of data communication through water channel in experimental water is measured and compared. The results show that the type and particle size of the agents will significantly affect its water properties, and the frequency domain component of the water communication signal will be affected by the agent’s concentration. By having a separate transmitter and receiver module in the water between the modules we can transmit the sea researcher’s biomedical conditions and interactions to the monitoring end available on the ship. The atmospheric conditions under the sea will be changing tremendously. It affects the sea navigators in too much trouble. It is difficult to monitor the health conditions of sea navigator after diving. Even if he dives below 20 meters his heart beat becomes uncontrollably changing. So even if his blood pressure lows dangerously it may leads to death. And there is no idea to save those navigators in those conditions. So here we propose a system to monitor heath conditions of a sea navigator while checking the heart beat reading while navigation. Using a communication system we can monitor a diving navigators heart beat even in ground. If we found his BP is lower in we can say him to enter the ground. So we can save the life of too many navigators.

The main feature of a BMS is to safeguard the battery and make the operation reliable and smooth. To achieve the same, Battery State of Charge (SoC) evaluation, Charge Control and Cell Balancing have to be implemented in the BMS. BMS performs many complex operations that require constant optimization of the BMS for the improvement of battery life cycle, engine performance, energy enhancement and security of the vehicle. The need for security increases with the increase in the control units that favor data theft and security of the vehicle. A Controlled Area Network (CAN) based communication control system fulfills the need of a closed environment security system that optimizes the BMS and minimizes cyber threat. The main objective of this study is to give a detailed analysis of two key components of an electric vehicle viz., the BMS and the CAN bus that is used for communication. This study also covers the general model circuitry diagrams that are used to integrate the BMS and CAN bus that can be implemented in the real world. This work also hopes to help the readers who are interested in pursuing work in this field of vehicular design.","PeriodicalId":13986,"journal":{"name":"International Journal of Engineering Research and","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89713460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The generated DC needs to be converted to AC for the AC loads or to connect to the grid without disturbing the grid performance. Multilevel inverters is a good option as the output voltage of a Multilevel inverter is a stepped waveform which approaches a sinusoid providing lesser harmonic distortion. As the number of levels are increased the harmonic distortion reduces but at the same time the number of switching devices and the DC voltage sources required increases, thus increasing the complexity of the system design and control. Multilevel inverter proposed in this paper uses only 7 switches to provide 15 levels of output voltage for renewable applications such as solar PV. As the number of switches used are less, the complexity and the control is reduced. Keywords—Multilevel inverter; 15 level MLI; reduced number of switches; total harmonic distortion.
