The characteristic of an inverter is to transform the dc power into ac power to fulfill out the requirements of load. Despite its advantage, the presence of harmonics in the output voltage reduces both the efficiency and the performance of the inverter. Several researches have been carried out since last three decades for eliminating the harmonics. Based upon several researches, it reveals that the Selective Harmonic Elimination Pulse-width Elimination technique (SHEPWM) has proven to be the best in eliminating lower order harmonics. But when calculus based methods are used for solving the non-linear transcendental equations, this technique has shown some complications. Artificial Intelligence (AI) techniques appear to be better in solving the above said equations. This review paper provides the performance of some AI techniques used for eliminating the harmonics in inverters. Based upon the information collected from various literatures and its results, conclusion has been made.</p> 2023-01-10T00:00:00+00:00 Copyright (c) 2023 Krithiga G, Mohan V, Chitrakala G, Senthilkumar S IMPACT OF CONSTRUCTION ACTIVITIES ON ENVIRONMENT 2023-01-18T05:25:40+00:00 Nagaraju Kaja Stuti Goyal <p>Construction processes and related activities have significantly aided in environmental pollution and degradation of environment, deforestation, and other environmental issues. Construction operations have a negative influence on the environment because of waste creation, consumption of resources, noise pollution, air pollution from construction dust, and foul odors from huge diesel-powered construction equipment and vehicles used for transporting materials. This study's objective is to evaluate how construction affects the environment in order to provide solutions for mitigation and strategies for enforcement. To acquire information from primary sources, a literature review was conducted. Although all these effects cannot be eliminated, but various mitigation strategies, such as Environmental Management System (EMS), Environmental Impact Assessment (EIA), Quantitative Risk Assessment (QRA), Green Building (sustainable construction), and Environmental Protection Agency (EPA) can be used. As a result, the government and construction stakeholders should make a conscious effort to effectively integrate and start enforcing the present approaches/initiatives during the construction processes. These measures should be monitored from start to finish and legislative laws should be formulated in order to spell out punishment for the scenarios of violations. It is also advised that construction stakeholders become more aware of, and learn about, the environmental implications of building construction operations.</p> 2023-01-18T00:00:00+00:00 Copyright (c) 2023 Nagaraju Kaja, Stuti Goyal FAILURE AND EFFECT DIAGRAM OF A 365KVA CATERPILLAR GENERATOR 2023-01-24T06:28:42+00:00 E.

O Ogbeide G.O Ariavie <p>Troubleshooting is one of the most tedious jobs in maintenance and required constant contact with similar problems in order have timely insight into the likely possible solutions that can aid the process of concluding on what will be the feasible solution. This research work is aimed at reducing the time that would be spent on fault tracing especially on 365KVA Caterpillar generator which uses the analyzed Fishbone diagram for Ignition System Sub-System, Fishbone diagram for Cylinder Block Assembly Sub-System, Fishbone diagram for piston and connecting rod and Fishbone diagram for Engine Cooling System Sub-System of the possible cause and effect that emanates from man, methods, measurement, material, machine and environment on the overall performance of the generator.</p> 2023-01-24T00:00:00+00:00 Copyright (c) 2023 Oghu, E., Ogbeide, O. O, Ariavie, G.O THE EFFECT OF BLOOD CLAM SHELL POWDER ADDITION ON SHEAR STRENGTH VALUE OF CLAY SOIL 2023-01-24T06:28:40+00:00 Noto Royan R.A. Sri Martini Mira Setiawati Revi Yulianti <p>Ground condition is an important aspect that influences performance under the load. An effort to overcome the load problem can be done by improving unstable soil through soil stabilization using blood clam shell powder. In order to determine the shear strength and changes in its value, it can be done by conducting the Triaxial UU test on a mixture of clay and blood clam shell powder with addition of 10%, 20%, 25%, and 30% of soil weight and 4% coal ash. Mixed soil was then stored in plastic for 24 hours to achieve evenly distributed moisture content. Laboratory testing was carried out with reference to ASTM (American Society for Testing and Materials) standards, aimed to calculate soil shear angle, cohesion, and soil shear strength values. The results showed that the addition of blood clam shell powder and coal ash increased the soil shear strength compared to the clay soil (without any addition). The highest shear strength value of 35,724 kPa was obtained by adding 25% blood clam shells.</p> 2023-01-24T00:00:00+00:00 Copyright (c) 2023 Noto Royan, R.A.

Senthilkumar Mohan V. Krithiga G. <p>In modern years several researchers contribute to renewable energy specifically solar as atmosphere responsive. Solar panels are an essential and chief constituent for solar energy selecting as they are active in transformation of solar radioactivity into electrical voltage correspondent. The principal concern in optimum generation of power from these solar panels is to be contingent on numerous characteristics mostly correlated to the sizing and modelling of photovoltaic (PV) panels for the essential presentations. An array of solar cells is castoff for generation of slight to average gauge power generation in numerous cases. Sizing of panels, the storing progression and application of electrical tracks in the procedure are some vital research qualities which together regulate and describe supreme power generation from solar panel. Parameter and circuit level modelling has been occupied as major problem of examination and several state of the art practices to govern the ideal sizing with respect to many circuit models such as single diode model (SDM) and double diode models (DDM) have been inspected in an widespread way in this review article. It offers the perceptions, features, and climaxes the strength and weaknesses of PV cell models. This article debates some algorithms and methods used in both SDM and DDM and a deep learning into the investigation of parameter assessments in each diode have been studied. Based on the showed evaluation, some commendations for upcoming research are provided.</p> 2023-01-26T00:00:00+00:00 Copyright (c) 2023 S. Senthilkumar, V. Mohan, G. Krithuga IMPROVING CLAY SOIL STABILITY WITH THE ADDITION OF RICE HUSKS THROUGH CHEMICAL METHODS 2023-01-26T05:26:16+00:00 Erny Agusri Ririn Utari Yoga Satria Putra <p>Soil stability is a mixture of soil with a certain material, the aim is to improve the technical properties of the soil so that it can technically meet certain requirements. Soil stability is a mixture of soil and other materials, for the purpose of achieving the correct gradation, so that the technical properties of the soil are better. Chemical stability is the addition of chemical elements to the clay with the addition of other ingredients, namely rice husk ash (ASP), so that a physical change is achieved and a change in the physical properties of the soil occurs, with an increase in the size of the soil load capacity (CBR). This study aims to obtain the appropriate variable for adding rice husk ash to the stability of clay as a stabilizer seen from the unconfined compressive strength test to obtain a capacity value of high load. The research method was carried out by testing the properties of soil index, soil compaction tests (standard proctor) and unconfined compression strength tests (Unconfined Compression Strength) in the laboratory. 200 with variations of 5%, 10% and 15%. Index property tests such as water content tests refer to ASTM D2216:2010, Sieve Analysis (ASTM D-422), Atterberg Limit, Liquid Limit (LL) (ASTM D-4318), and Specific Gravity (Gs) (ASTM D-854). Soil mechanical properties test (proctor standard) (ASTM D 698), free compression resistance test (ASTM D 2166). The conclusive results show that the free compressive strength value increased in the mass without hardening with a 10% husk ash percentage of 1.0005 kg/cm2 and a Cu value of 0.502 kg/cm3. While the results of the free compression strength test with curing for 24 hours, the highest bearing value occurred, in the original soil variation of 1.000 kg/cm3 and a Cu value of 0.500 kg/ cm3. For the value of the free compressive strength, there is a decrease, namely at variations of 5%, 10% and 15% with a time of 24 hours.</p> 2023-01-26T00:00:00+00:00 Copyright (c) 2023 Erny Agusri, Ririn Utari, Yoga Satria Putra
