Ogbuokebe ogbuokebekc@gmail.com <p>With the rapid increasing bandwidth demand mainly driven by the development of advanced broadband multimedia application, such as video-on-demand (VoD), interactive high-definition digital television (HDTV) and video conference, new access network solutions that provide high capacity are highly needed to satisfy these emerging services. In a largely populated and technologically exposed institution such the University of Port Harcourt, this demand is truly great. The Passive Optical Network (PON), which utilizes the Fibre Optic Technology, is a suitable solution to this problem. Hence this is geared towards the design and simulation of a Passive Optical Network for the University’s campus district. This Campus based Local Area Network consists of the Various Faculty buildings, the Senate building which is the central administrative building, and was centralized at the Information and Communication Technology Center (ICTC), which served as the Central Office of the network. The Wavelength Division Multiplexing (WDM) technique was utilized because of its dedicated bandwidth for each subscriber and more flexible bandwidth management. The validation was carried out on a virtual computation environment called OptiSystem©.</p> 2021-04-06T06:22:55-04:00 Copyright (c) 2021 R. O. Okeke, V. E. Idigo, M. O. Akemi, S. K.

Metskhvarishvili m.metskhvarishvili@gtu.ge <p>The electrical properties of <em>n</em>-type crystals of InAs compound, grown from stoichiometric melt by the horizontal zone melting method, have been investigated in the temperature range of 4.2 K-300 K before and after fast neutron irradiation up to high integral fluences of 2×10<sup>18</sup><em>n</em>∙cm<sup>-2</sup>. At a fixed temperature electrons concentration (<em>n</em>) increases almost by one order during irradiation, and practically does not change with increasing of temperature. <em>n </em>increases only slightly by increasing of temperature near 300&nbsp;K, both before and after irradiation. When &nbsp;<em>≥ </em>4×10<sup>18</sup>cm<sup>-3</sup> the change of &nbsp;during irradiation is negligible. Comparison of experimental data of mobility with theory shows that the privileged scattering mechanism of electrons at 300 K is scattering on optical phonons in InAs with &nbsp;10<sup>16</sup>-10<sup>17</sup> cm<sup>-3 </sup>and scattering on ions of impurity in InAs with <em>n</em>~10<sup>18</sup>-10<sup>19</sup> cm<sup>-3</sup>. The analysis shows that during irradiation point type scattering centers of donor-type structural defects with shallow levels in the forbidden zone appear. Consequently, the mobility decreases during irradiation. At 300 K in &nbsp;sample with electrons concentration of 3×10<sup>16</sup> cm<sup>-3</sup> the mobility decreases by 5 times after irradiation, which is equivalent to the formation of 1.5×10<sup>19</sup>cm<sup>-3</sup> charged point scattering centers.</p> 2021-04-06T06:43:42-04:00 Copyright (c) 2021 E.

Ebuehi osaretinebuehi2007@gmail.com Kingsley Abhulimen brchukwu@yahoo.com Daniel O. Adebesin lovely.l100@yahoo.com <p class="Abstract">Recently, fuel gas from water has become the center of attention because it is a renewable source of energy and eco-friendly. In this study, the hydrogen gas simulated was obtained from the high-temperature water splitting electrolysis model, because it is more efficient than the low-temperature water splitting electrolysis process. It also releases oxygen as a byproduct. The high-temperature electrolysis model is made up of three loops: primary high-temperature helium loop, secondary helium loop, and high-temperature electrolysis loop. Hydrogen gave a temperature of 27.2<sup>0</sup>C, a pressure of 49.5 bars, and a molar flow of 84.02MMSCFD. The hydrogen gas from a high-temperature electrolysis model is simulated with a CO<sub>2 </sub>gas stream to produce methane and water, also releasing unreacted carbon dioxide and hydrogen. Key parameters such as molar entropy, molar enthalpy, heat flow, and cost flow were evaluated by Aspen HYSYS V8.8. The simulation model used for this work is the Sabatier Process Model. In this model, Continuous stirred tank, Converter, Equilibrium, Gibbs, Plug flow reactors were used to generate methane. The Converter reactor gave the highest yield of methane gas with a mole fraction of 0.2390. Key benchmarks, including temperature, heat flow, cost flow, cost factor were varied to see how they can affect methane gas and other products.</p> 2021-04-12T05:54:16-04:00 Copyright (c) 2021 Osaretin N.I.

Azuar Rizal azuarrizal@unsam.ac.id <p class="Abstract">Building Integrated Photovoltaics (BIPV) is a combination of electrical technology from photovoltaic solar panels (PV) with building construction. The PV panel was mounted onto the frames attached to the building's main outer wall. When solar radiation energy comes into contact on the PV surface, some part is reflected in the surroundings while mostly absorbed in the PV panel. The energy absorbed is converted into electricity while the rest dissipates into thermal energy, which increases the surface temperature of PV. The increases in the panels' surface temperature negatively impact the electrical output and PV panels' long-term reliability. One of them is the use of phase change materials (PCM) as heat storage materials. This research also emphasizes the use of beeswax as a material for storing heat energy. Using the T-History method by fusing beeswax, show that the temperature range between 49,40 to 57.15 <sup>o</sup>C with latent enthalpy 151.65 kJ/kg. In this research, we tested the use of PCM as a heat storage material for PV panels. Two types of containers to accommodate PCM are used, triangular containers and semicircular containers. From the test results, it was found that beeswax can function well as a heat storage so that the surface temperature of the PV + PCM panel is lower than that of standard PV. So that the voltage generated is higher than standard PV panels.</p> 2021-04-12T06:00:06-04:00 Copyright (c) 2021 Razali Thaib, Hamdani Umar, T.

Reliable electric power systems serve customer loads without interruptions in supply voltage. Electric power generation facilities must produce enough power to meet customer demand. Electrical energy produced and delivered to customers through generation, transmission and distribution systems, constitutes one of the largest consumers markets the world over. The benefits of electric power systems are integrated into the much faster modern life in such extent that it is impossible to imagine the society without the electrical energy. The rapid growth of electric power distribution grids over the past few decades has resulted in a large increment in the number of grid lines in operation and their total length. These grid lines are exposed to faults as a result of lightning, short circuits, faulty equipment, mis-operation, human errors, overload, and aging among others. A fault implies any abnormal condition which causes a reduction in the basic insulation strength between phase conductors or phase conductors and earth, or any earthed screens surrounding the conductors. In this paper, different types of faults that affected the electric power distribution grid of selected operational districts of Electricity Company of Ghana (ECG) in the Western region of Ghana was analyzed and the results presented. Outages due to bad weather and load shedding contributed significantly to the unplanned outages that occurred in the medium voltage (MV) distribution grid. Blown fuse and loose contact faults were the major contributor to unplanned outages in the low voltage (LV) electric power distribution grid.</p> 2021-04-12T06:22:23-04:00 Copyright (c) 2021 Godwin Diamenu https://ejers.org/index.php/ejers/article/view/2411 Experimental Study of Beeswax / Rice Husk Ash Phase Changes Material as Energy Storage in Concrete 2021-04-20T00:05:10-04:00 Razali Thaib razalithaib@unsyiah.ac.id <p>Buildings with lightweight concrete are currently used as a solution for mass housing construction which is relatively cheaper, although it does not provide indoor thermal comfort due to the use of this building material. Lightweight concrete building materials are able to store heat for a long time, so that at night the heat is released indoors. The combination of building materials and PCM is an efficient way to increase the storage capacity of thermal energy in building components. The purpose of this study was to determine the compressive strength of the concrete if the coarse aggregate (gravel) was replaced by part of the gravel material using the Phase Change Material of beeswax (beeswax) according to the required percentage starting from 0%, 5%, 10%, 15% and if the aggregate was fine. (Sand) is partially replaced aby using Rice husk ash with various variations starting from 0%, 5%, 10%, 15%. In addition, this utilization is a good alternative, because there will be a process of utilizing rice husk ash which was previously wasted while these items can be used or processed into additives to the concrete mixture.</p> 2021-04-13T08:23:28-04:00 Copyright (c) 2021 Razali Thaib https://ejers.org/index.php/ejers/article/view/2397 Design and Implementation of an Esp32-Based Smart Embedded Industrial Poultry Farm 2021-04-20T00:05:10-04:00 Longinus S. Ezema longinus.ezema@futo.edu.ng Elochukwu C. Ifediora ifedioraelochukwu@gmail.com Akande A. Olukunle akandeoluk@gmail.com Nnaemeka C. Onuekwusi nnaemekaonuekwusi@yahoo.com <p class="Abstract">Many poultry farmers are performing diverse operations manually. They, therefore, experience a huge financial loss as a result of their inability to properly automate the monitoring and control of environmental factors such as temperature, humidity, air quality, and to ensure an adequate supply of light and water. These factors adversely affect the chicks and lead to respiratory, digestive, and behavioural disorders. This affects the chicks’ food intake and leads to an increase in mortality rate and chances of diseases. Therefore, this paper seeks to address these factors by developing an embedded poultry farm. The system was developed using an advanced yet low-cost and low-power System-on-Chip offering WiFi baseband processor and a plethora of peripheral interfaces for the actuators and sensors while Arduino emulator in Proteus 8 was the tool used for the design simulation. The system when tested was able to sense environmental parameter status wirelessly and responds accordingly to regulate and maintain an optimum condition for improved health condition for the chicks. The automated system will help for the purpose of improving productivity and environmental or climatic conditions in the poultry farm, making it conducive for the broiler chicks.</p> 2021-04-15T09:05:49-04:00 Copyright (c) 2021 Longinus S.
