Simulation of Gas Turbine Operations for Improved Performance[ ]


The response mode of some pre- specified parameters of gas turbine plant was studied and analysed using the scientific tool of simulation by varying the controlled variables, namely, flow rates, compressor inlet temperature and turbine inlet temperature. The results were achieved by following some steps which includes; determining the relationship that exist between components in the form of mathematical models, the equations from the mathematical models were solved on a visual C# environment.

Application of Entropy Model to Geophysical and Satellite Data for Groundwater Vulnerability in a Typical Basement Complex[ ]


Groundwater Vulnerability of Ogbese Area Southwestern Nigeria, have been evaluated using the integration of Geophysical and Satellite Data. Five (5) parameters were considered in achieving this aim; namely Topsoil Resistivity (TSR), Hydraulic Conductivity (HC), Longitudinal Conductance (LC), Topographic Slope (TS) and Drainage Density (DD). Multi-criteria decision analysis technique was employed to assign weight to each of the parameters using the concept of Entropy model. In order to evaluate the groundwater vulnerability of Ogbese, twenty eight (28) Vertical Electrical Sounding (VES) points were occupied.

Determinants of Performance in the National Achievement Test among Augustinian Schools in Central Luzon[ ]


The present study how student, teacher, and administrative factors affect the performance of students in the National Achievement Test (NAT). Every year, the Department of Education undertakes the National Achievement Test to take a snapshot of how students in key learning stages are achieving the desired learning outcomes of the national curriculum. Drawing from various findings in the research literature, the present study aims to clarify how student, teacher, and administrative factors affect performance in standardized testing like NAT.

Harmonic Reduction in multilevel inverter connected with PV Grid: A Review[ ]


In recent years, multilevel inverters have gained more attention for top power applications. A multilevel inverter not only achieves high power ratings, but also enables the utilization of renewable energy sources. Single phase inverter is widely used for stand-alone systems and micro-grid application. The foremost limitation faced by multilevel inverters are, number of switches required large which finishes up in higher switching losses.

MOIBLE PAYMENT[ ]


The advancement of Technology in the Telecommunication sector and information technology innovation give rise to several payment methods which include online payment or e-payment , MasterCard, credit card and debit card which are only limited to developed countries and urban areas. Which need to setup pc or laptop to access internet or searching for cash machine before payment transaction can be made. But there is a new type of payment system that is convenience, easy to use, accessible at any time anywhere payment transaction can be made via the use of mobile handsets.

THE IMPORTANCE OF USING RADIOTRACER IN DIAGNOSING CANCER[ ]


Nuclear Medicine is a medical specialty that allows modern diagnostics and treatments cancer using radiopharmaceuticals original radiotracers (drugs linked to a radioactive isotope). Radiopharmaceuticals are considered a special group of drugs and thus their preparation and use are regulated by a set of policies that have been adopted by individual member of countries. The radiopharmaceuticals used in diagnostic examinations are administered in very small doses. So, in general, they have no pharmacological action, side effects or serious adverse reactions.

Experimental Study on Geopolymer Concrete subjected to Sulfuric Acid Solution[ ]


The most promising advantages of the geopolymer concrete are: lower harmful emissions, converting a variety of waste streams into useful by-products, higher resistance to corrosion and fire, higher compressive and tensile strengths and improved durability properties. This paper presents the experimental investigation done on performance of geopolymer concrete subjected to severe environmental conditions. Five geopolymer concrete mixes and one conventional OPC concrete mix were investigated.

MANAGEMENT OF ARTERIAL HYPERTENSION IN PATIENTS WITH CHRONIC KIDNEY DISEASE[ ]


Hypertension (HTA) is a global public health problem, and is considered to be one of the major risk factors for heart disease, stroke and kidney failure. Chronic kidney disease (CKD) is a complication of uncontrolled hypertension. The positive correlation between CKD and HTA is very complex and the impact of HTA on the progression and deterioration of renal function is a multifactorial mechanism increasing the risk of both cardiovascular disease (CVD) and cerebrovascular disease.

Technological Interventions for Augmenting Income of Rural Households in India[ ]


One of the central issues which policy makers constantly try to address in developing countries is to explore ways to augment income of rural households. India being an agrarian economy, most of its population depend on farming as main source of income. But, large section of the farming population is distressed and look for alternative income augmenting avenues. A possible solution to enhance income of farmers is adopting technology in farming practices. With this background, the paper based on secondary data sources explores how technological interventions can help farmers to augment their income

EVALUATION OF PHYTOCHEMICAL CONTENT OF CALOCYBE INDICA ISOLATED IN NIGERIA FOR A POSSIBLE THERAPUTIC USE[ ]


Calocybe indica is a common mushroom species in Nigeria. Oral reports in Nigeria suggest that this mushroom species has some therapeutic applications. This study was therefore designed to evaluate the phytochemical composition of this mushroom species with the intent of determining its possible medicinal uses. Pure culture of this mushroom species obtained from the wild was isolated and cultivated on a cassava based substrate to produce the fruiting body. The produced fruiting body was evaluated for its phytochemical content.

SMART COVID-19 PRECAUTIONARY SAFETY SYSTEM[ ]


The main vision of the project is to provide safety due to the issue of infection of coronavirus. From 2019 through 2020 COVID-19 has become a pandemic among the whole world. The way is to prevent infection is to maintain a safe distance, use hand sanitizer frequently, maintain distance from unknown people. So, the system is built to provide safety to home and commercial places. The system protects by notifying that the person is a member of that family or not.

Evaluation of dimensions of a vehicle using Velodyne and Blickfeld LiDAR[ ]


LiDAR acts as an eye of the autonomous vehicles and help them to drive smoothly without collisions. In this research paper, we focus on the calculation of dimensions of a car using two LiDAR sensors. Velodyne Puck and Blickfeld Cube 1 sensors were used to capture the dataset of a car in two different situations which were then evaluated using Python. Further, we compare the results of both the sensors and the 3D bounding box. Thus, we conclude that when the car is coming directly towards the sensor, Blickfeld LiDAR was more accurate whereas Velodyne LiDAR produced accurate results when the car is going in a direction parallel to the sensor.
