Automatic Power Switching Mains for Various Sources
Abstract: This project's major objective is to autonomously choose from four possible power sources—mains, generator, inverter, and solar—to guarantee a load's continuous power delivery. This is crucial due to the rising demand for electricity and the frequent power disruptions affecting industries, hospitals, and households. Establishing an alternative power source is imperative to address this issue. In this project, four switches are utilized to simulate the failure of individual power sources. Pressing …

Selected Heavy Metals Levels (Cu, Cr, Cd, Pb, Fe) in Gwadabawa Lake, Sokoto State, Nigeria
Abstract: The main aim of this work was to determine the concentrations of some heavy metals, specifically Cu, Cd, Pb, Cr and Fe in Gwadabawa lake, Gwadabawa Local Government, Sokoto State using standard methods (atomic absorption spectroscopy) and materials of analytical grade. The results were analyzed. The range of Fe concentration was 0.01 ± 0.001 to 1.37 ± 0.3(ppm), and range of Cu concentration determined was 0.00 to 0.02±0.008(ppm). The range …

Causes and Measures to Control Root Rot Fungus in Mulberry Ecosystem
Abstract: Root rot is a severe plant disease caused by various soil-borne fungi, including Phytophthora sp., Pythium sp., Rhizoctonia sp., Fusarium sp., and Armillaria sp. These pathogens attack plant roots, leading to decay, stunted growth, wilting, yellowing leaves, and plant death. Root rot typically develops in waterlogged soils with poor drainage, as these conditions create an environment favorable for fungal growth. Factors such as warm temperatures, compacted soil, improper watering practices, …

Exploring the Efficiency of Leading and Lagging Indicators in Algorithmic Trading
Abstract: This paper details a comparison of the overall performance of leading and lagging technical indicators used in algorithmic trading over an extended period. While much of the prior research focuses on index price forecasting and some on statistical arbitrage derived from these predictive techniques, there is a scarcity of studies that assess and evaluate trading strategies. The strategies considered for the study were tested on historical data of the 50 …

Primality Testing: A Comprehensive Analysis of Methods and Time Complexity
Abstract: This paper examines various primality testing algorithms and analyzes their time complexity. The algorithms we examine include the trial division, which is straightforward but becomes inefficient with large numbers; Fermat’s little theorem which is a probabilistic method included in Monte Carlo type of randomized algorithm; the Solovay–Strassen, based on properties from number theory, particularly those related to Euler’s criterion and Jacobi symbols; and the Miller–Rabin Probabilistic Test, which balances efficiency …

Strategy for Improving Software Maintenance Using Machine Learning for Security Requirements: A Review
Abstract: Within the area of software technical education, the significance of software defect discovery has increased as a research focus to enhance program reliability. By maximizing testing resources and assisting developers in identifying potential problems using program defect predictions, program dependability is increased. Applying software engineering (SE) techniques to critical and intricate systems, like networking and security systems, is imperative. Traditional methods of predicting software maintainability have limitations, particularly in balancing …
