The global economy has faced an unprecedented threat from the COVID-19 outbreak. The current illness is ravaging Africa at an exponential rate, and all of the continent's nations are experiencing the effects of the epidemic. In this study, we used the COVID-19 outbreak as a case study to examine the prediction of the economic impact of the pandemic in Sub-Saharan Africa (SSA). We adopted several models to work on the dataset to compare which one worked best for all 3 target variables and we d...
ABSTRACT ICT (Information and Communication Technology) has greatly changed contemporary education. The ICT solutions offered enrich learning environments and provide staffs with numerous opportunities. However, even though ICT can enhance education quality, there are many staffs that are unwilling to adjust to the changes brought about by ICT. One of the most crucial inhibitory factors that make staffs reluctant to utilize ICT in education is the lack of their training on ICT. Thus, the purp...

ABSTRACT This project is a power bank for laptops, and it is designed to serve as a back up to a laptop whenever there is no power supply and it has a variable knob which controls the output voltage to a desired value. The problem is that we carry different chargers for different gadgets. Though the cost of producing is more costly than the normal chargers we have around but it can serve as a reliable backup considering the problem and solution above a power bank for laptop charger is neede...
In an era marked by technological advancements and a growing demand for secure and transparent electoral processes, the integration of blockchain technology into online voting systems has emerged as a promising solution. This research paper presents a comprehensive exploration of the design, implementation, and implications of an online voting system built upon blockchain technology. Through an in-depth analysis of existing electronic voting challenges and the potential of blockchain, this pa...
The frequency and severity of cyber- attacks have surged, causing detrimental impacts on businesses and their operations. To counter the ever-evolving cyber threats, there's a growing need for robust risk assessment systems capable of ef ectively pinpointing and mitigating potential vulnerabilities. This paper introduces an innovative risk assessment technique rooted in both Machine Learning and graph theory, which of ers a method to evaluate and foresee companies' susceptibility to ...
As Modern-day data increases in terms of dimensions (Instances X attributes), Single Feature Selection Techniques (SFST) often have certain biases and fail to provide optimal performance in machine learning models. To overcome the challenges associated with using SFST on large datasets, an Ensemble Feature Selection Technique (EFST) is proposed that includes multi-filter-based feature ranking selection and a wrapper-based feature subset selection methods for feature extraction on the Cana...
ABSTRACT Design and implementation of weather forecasting package for aviation industry is discussed in this research work using Sam Mbakwe Airport, Owerri – Imo State as a case study. With its objectives research work as follows: To help aviation Meteorologists issue accurate weather forecasts. To enable aviation industry to make decisions on control based on information given etc. This research work reviews the background and general idea of weather forecasting which motivated me to go in...
ABSTRACT Web Based Census Management System includes the sets of methods that allow us to measure the dimensions and dynamics of populations. The aim of the study is to Design and Implement a Web Based Census Management System. In achieving this aim, the following specific objectives were laid out as follows to develop a: computerized software that automatically stores and retrieves all information on human population, reliable system that could be used in collecting data/information on huma...
ABSTRACT DevOps is the collection of cultural practices, philosophies, mechanisms, and technology that assists in increasing the ability of an organization to distribute services and applications at a faster pace. Unlike the traditional software development and infrastructure management processes (also known as the Waterfall Model), DevOps is inspired from the Agile Project Management, meaning that the entire project is broken down into several phases, aiming for continuous improvement at eve...
ABSTRACT The purpose of this Research is to develop a computerized process of applying for and paying for stamp duty. A case study of Federal Inland Revenue Service Ikot Ekpene. The study critically analyses the manual method of collecting stamp duty in Nigeria and uses ideas so gathered to design a new program (Electronic Stamp Duty Payment System) for use by the Tax Administrators in Federal Inland Revenue Services, Credit Officers in the bank, insurance companies, hire purchase companies...
An Introduction to Computer Science and Problem Solving
INTRODUCTION TO PROBLEM SOLVING An algorithm is a sequence of simple steps that can be followed to solve a problem. These steps must be organized in a logical, and clear manner. We design algorithms using three basic methods of control: sequence, selection, and repetition. 1.1 Sequential control. Sequential Control means that the steps of an algorithm are carried out in a sequential manner where each step is executed exactly once. Let’s look at the following problem: We need to obtain the t...
A computer is an electronic device that receives input, stores or processes the input as per user instructions and provides output in desired format. Input-Process-Output Model Computer input is called data and the output obtained after processing it, based on user’s instructions is called information.
What is Computer Science? 6 • Computer Science can be summarized with two simple words: problem solving. • Computer Science is the study of problems, problem-solving, and the solutions that come out of this problem-solving process. • Given a problem, the goal is to develop an algorithm to solve the problem. • An algorithm is a step-by-step list of instructions to solve the problem.
