    Iterative Method for the Numerical Solution of Optimal Control Model for Mosquito and Insecticide
    (published by Nigerian Society of Physical Sciences, 2024-04-09) Adeniyi Samson ONANAYE
    A linear multistep method is transformed into an iterative method based on the Patade and Bhalekar technique for the numerical solution of an optimal control problem modeled for mosquito and insecticide management using forward-backward sweep methods via Pontryagin’s principle. Stability and convergence analysis of the iterative method are carried out and it is found to be stable, convergent, and of order four. Results obtained by the method clearly show that the population of mosquitoes can be minimized to a large extent using the new iterative method while reducing the harmful effects of the insecticide, which subsequently reduces the spread of malaria.

    AHP Algorithm in Data Diffusion Across a Social Networking Platform
    (Corpus Intellectual, 2023) Adeniyi Samson ONANAYE
    The Social Networking platforms (SNPs) have become major media of communication, information dissemination and sharing. SNP ignores the constraint of distance, time and type of information during communication among users. It is obviously seeming the best platform when it comes to marketing, advertisement and information transmission. In this paper, content ranking model was used to advance on how contents on a social networking platform can be shared among users faster and hereby improving the rate of information transmission over the network. Analytic Hierarchy Process (AHP) algorithm was deployed to find the level of importance in the constructed metadata.

    Poverty alleviation programs in Nigeria
    (Cogent Social Sciences, 2024-07-01) Adesina, Olumide Sunday
    the measurement of poverty in developing nations are carried out to reduce the severity of poverty in such nations. there are Governmental and non-Governmental organizations that take poverty reduction as a project, and one such is a faith-based oraganisation such as World Mission agency (WMa). this study focuses on the poverty alleviation of WMa and evaluates the impact accessibility and significance of WMa poverty alleviation programs. a survey was conducted at ota, ogun state, nigeria. Data collected were analyzed using the principal component analysis and the t-test. the results obtained were discussed, one vivid findings of this study was that the effectiveness of the poverty alleviation programmes of the World Mission agency in ota was based on the systematic establishment of programmes that address the needs of people at the grassroots level and recommendations were made which include that the federal government of nigeria should take a cue from the World Mission agency Poverty alleviation Programs

    Investigating Behavioural Characteristics for Psychopathic Personality Traits
    (BP International, 2024-07-20) Adesina, Olumide Sunday
    In this work, a survey was conducted in five selected towns in Osun State, Nigeria, based on seventeen identified behavioural characteristics using a developed structured questionnaire to collect data on identified behavioural characteristics that could trigger psychopathy personality traits. Psychopathic traits have eroded our society as they increase daily, thus leading to increased crime. It refers to the full range of physical and emotional behaviours that humans engage in. Physical or verbal aggression between spouses, siblings, or parents who use it as punishment for their children begins at home. Because of misunderstandings, neighbours frequently demonstrate hostility, pessimism, trust, and envious behaviours. Two personality traits considered in this work are aggressiveness and goal setting, while the considered behavioural characteristics are family upbringing, confidence in government, society values, industrialization, civilization, unemployment rate, technology advancement, socio-political class, impunity, environmental impact, embracing foreign culture based on materialism, religion believes, peer group influence, academic attainment, high wealth procession, family believes, and power intoxication. The data harvested from the questionnaire on behavioural characteristics from the five hundred and eight respondents were subjected to principal component analysis to investigate behavioural characteristics that are likely to be responsible for psychopathic traits in humans. Results from the principal component analysis confirmed that family upbringing, confidence in government, society values, industrialization, and civilization significantly contributed to psychopathic traits. Goal-setting is highly influenced by foreign cultures, high money possession, religious views, power intoxication, and technical advancement. These findings were obtained from a binary logistic regression study that used aggression and goal-setting as dependent factors. Conversely, it was discovered that the aggression personality trait was significantly influenced by power intoxication, environmental impact, impunity, and government confidence. Therefore, based on the available data in this study and the analysis carried out, civilization and confidence in government are the main significant behavioural characteristics that trigger personality traits in the region covered in the study. Future works can be extended to cover the entire country for a more robust study in investigating psychopathic behavioural characteristics.

    Advanced Principal Component Analysis of Various Risk Factors of Hepatitis B Prevalence in Nigeria
    (Tanzania Journal of Science, 2024-09-30) Adesina, Olumide Sunday
    Hepatitis B virus (HBV) is an infectious disease globally estimated to have caused between 500,000 to 1.2 million deaths annually. HBV prevalence is still high in Nigeria. Thus, this research aimed to identify factors germane to the widespread of HBV infection in an apparent clinical survey. The methods of analysis used were frequency, percentage and Principal component analysis (PCA). This was achieved through hospital record extracts of consultant hepatologists and the dimensionality reduction of the acquired data while retaining essential factors that are germane to the prevalence of HBV infection. The findings revealed that out of seventeen components evaluated in the study, the PCA retained 15 components of which Eigen-values are greater than 1.00. The symptoms retained in every component were fever, muscle pain, fatigue, loss of appetite, blood in vomit, jaundice, pale stool, nausea, blood in faeces, weight loss, malaise, abdominal pain, joint ache, swollen of lower extremities, confusion and yellow eye. The symptoms were listed in accordance with their level of relevance for diagnosing HBV in patients, and all the variables retained accounted for 94.278% variation in the prevalence of HBV infection, with the majority of the infected populace found among the adults (18 -64 years).
