Kavitha kavitharavi2226@gmail.com M. Nambiraj nambiraj0101@gmail.com R. Praveen Kumaar praveenkumaarraj@gmail.com N. N. Harish Kumar harishkumar.svce@gmail.com <p>Fuel cells are the devices that convert chemical energy into electrical energy through an electrochemical reaction. Direct Methanol Fuel cell (DMFC) is a proton exchange membrane fuel cells in which methanol is used as fuel. Its high energy density makes it suitable for fuel cells. Even though carbon dioxide is produced, there is no production of sulfur or nitrogen oxides. The problems usually occurred while working with DMFC are methanol crossover, condensation of methanol, water management and carbon dioxide release. In that the uneven flow distribution, accumulation of carbon dioxide bubbles in the fuel cell are the major issues in DMFC. To prevent these issues, this work focuses on the theoretical and experimental studies on development of fuel cells with special importance to geometry of the manifold. This paper provides the optimal solution for preventing uneven flow distribution that is the usage of squoval shaped manifold which is the combination of both square and circle. Performance of DMFC with squoval shape manifold is evaluated experimentally and is compared with square shape manifold and rectangle shape manifold geometry design.</p> 2020-08-05T07:45:51-04:00 Copyright (c) 2020 Govindarasu Ramasamy, R.

This paper focuses on a shell-and-tubes heat exchanger that involves two fluids (hot water and cold water) in contact with each other while the cold water flows through the tubes and hot water through the shell. Heat exchangers have special and practical applications in the feed water cooler in the process industries, power plants, chemical plants, refineries, process applications as well as refrigeration and air conditioning industry. The design calculations were carried out to determine the specifications of essential parameters for the development of the heat exchanger, data generated from the theoretical formulae were used to fabricate the heat exchanger using some locally available and durable materials, and the performance of the system was evaluated. Some of the parameters evaluated include heat duty, capacity ratio, effectiveness, overall heat transfer coefficient, and fouling factor. The heat exchanger was tested under various flow conditions and the results obtained were as follows; cold water inlet temperatures of (26, 26, 26, 27and 27) ºC increased to (59, 44, 39, 47 and 35) ºC after (10, 7½, 6½ &nbsp;8,&nbsp; and 6) minutes and the hot water temperatures decreased from (100, 80, 75, 87 and 73) ºC to (73, 59, 55, 62 and 50) ºC, respectively. The design data and test data were compared in terms of the heat duty, capacity ratio, effectiveness, overall heat transfer coefficient, and fouling factor, the deviation is found to be 22.87%, 13.99%, 8.98%, 43.30%, and 43.30% respectively. The results obtained proved that the heat exchanger was effective, reliable and provides a good technical approach to evaluate the thermal performance of the heat exchanger and useful in conducting heat and mass transfer practical in thermodynamics laboratory.</p> 2020-08-13T06:39:42-04:00 Copyright (c) 2020 Bashiru Abdulmumuni, Adedeji Mathew Ayoade, Ologunye Opeyemi Buhari, Azeez Rasheed Olatunde, Fanifosi Johnson Olaniyi https://ejers.org/index.php/ejers/article/view/2007 The Real Unıverse Model 2020-08-13T07:17:40-04:00 Mammadov Sabir Ahmedovich m.sabrikenan@rambler.ru <p>The developed cosmogonic theory and laws explain the objective solution of the problem of cosmogony - the universe, antiquity, solar system, planets and their satellites the origin and development, as well as their structure and chemical composition.

Thus, automatic3D Human Action Recognition is an area that has seen significant research effort. In work described here, a human’s everyday 3D actions recorded in the NTU RGB+D dataset are identified using a novel structured-tree neural network. The nodes of the tree represent the skeleton joints, with the spine joint being represented by the root. The connection between a child node and its parent is known as the incoming edge while the reciprocal connection is known as the outgoing edge. The uses of tree structure lead to a system that intuitively maps to human movements. The classifier uses the change in displacement of joints and change in the angles between incoming and outgoing edges as features for classification of the actions performed</p> 2020-08-13T09:20:17-04:00 Copyright (c) 2020 Muhammad Sajid Khan, Andrew Ware, Misha Karim, Nisar Bahoo, Muhammad Junaid Khalid
