Evaluation of the Weather-Influenza Pattern with a Regression Model Approximation to Causality (Published)
Once at a time, this author starts a research in the relations between Australia’s number of case in influenza and weather. The outcome has been hypothesised with a structural equation model (SEM). In this paper, the author tries to evaluate the model. It is true that one can apply the evaluation to both of the formative measurement model and structural model through certain suitable procedures. At the same time, this author approximates the model by linear regression method. The result is one can apply the regression to the Hayes’ Process model and find out the wanted model with mediation and moderation effects. In addition, one can also use the Granger Causality Test to examine all of the hypothesised causal relationships between those independent variables such as temperature, wettest_1, concentration of carbon dioxide, strongest wind and coolest and the number case of influenza infected etc. The final outcome is that Hayes’ model 91 is the best mediated one with carbon dioxide as the moderated factor. This author will also explain in details why we have the above prescribed Hayes’ model 91 as the proposed regression model approximation to causality from the SPSS data analysis.
This is a paper review of the work presented at the Royal Agricultural University, Cirencester, United Kingdom. Using library research and reflection, document, journal papers and content analysis were used to generate data. The Sub Saharan African region covered in the paper is that of seven countries. The paper describes the role of agricultural extension models in Sub-Saharan Africa, as well traces the various extension models currently being developed or implement in Sub-Saharan Africa, namely; the top down approaches; from international institutions/ national governments and participatory approaches/bottom-up that engage farmers in decision making. Currently, there are six basic extension approaches/models in diverse stages of development and implementation in developing countries. These models have been structured in a more analytical way around key themes; top down; participatory; demand-led; group versus individual targeting; private sector and free/paid extension services. The reality is that pluralism of models has been employed in various forms in most countries in Sub-Sahara Africa. The paper critically examined seven models, including National Public Extension Model, Training and Visit (T&V) Extension Model, Private Sector Model, Fee-For-Service Extension Models, Farmer Field School Model, Non-Governmental Organization Extension Model, Commodity Extension and Research Model.

Characterization and Modelling Of Air Pollutants Transport from Panteka Market, Jimeta-Yola, Nigeria (Published)
The primary motivation of the current research was to apply Land GEM model to predict gaseous pollutant mobility by means of pollutant concentrations, annual waste mass received, and dumpsite open year from the research area. Land GEM model is believed to have wide application on emission rates from landfills/dumpsites using both site specific and default model parameters. Emission concentration levels were achieved through field and laboratory experimental work from vegetable waste dumpsites using scientific calibrated instruments. Data obtained were applied on Land GEM computer based software; version 3.02 in order to predict air-pollutant transport from the market environment and her surroundings. The model was tested to ascertain its validity where the measured and simulated values indicated good match with an error of 3.8% .The closure year of the case study dumpsite A was predicted to be in 2074 having reached hazardous level in 2024 while control dumpsite B predicted a closure year of 2023 and hazardous level in 2019 with modeling efficiency of 64%. Understanding the types of gases emitted from decomposing vegetable waste dumpsites (CH4, CO2, NMOC, H2S) and their transport pattern could go a long way to ensuring control measures of these pollutions there by having a sustainable zero wastes market to boost economic activities under pleasant environment; hence healthy environment is a prerequisite of healthy life, and fighting pollution is definitely the best way of healthy life.

This paper presents a corrosion rate model for mild steel in hydrochloric acid. A non-linear corrosion rate equation was developed, validated and used to relate the acid point, pH of hydrochloric acid as corrosive medium for mild steel to other variables like corrosion rate and substrate immersion period. The inhibitor used is Sinclair synthetic paint – an organic inhibitor. The effect of variables on corrosion rate has been investigated using non-linear regression analysis. The derived model is an exponential decay function of two input factors. The coefficient of correlation between the calculated and experimental data indicates good performance of the derived model.
Modeling the Evolution in the Concentration of Solids Based On Time of The Mewou River in the Mifi Basin (Published)
The objective of this study is to evaluate and model the evolution of the concentration of solids, as a function of the time of the Mewou river, in the Mifi watershed. We have determined from the samples taken from this watercourse and from the specialized laboratories the concentrations of soil exported. The MATLAB software allowed us to simulate the evolution of the concentration of solids, according to the time of this stream. This evolution is characterized by the polynomial model equation of degree nine with a correlation coefficient of 0.5702 and a coefficient of determination of 0.325: Cs = a* t 9 + b* t 8 + c* t 7 + d* t 6 + e* t 5 + f* t4 + g* t 3 + h* t 2 + i* t + j

A Model for Planning and Implementing Curriculum Change in Private Higher Education in Botswana (Published)
This paper examined the role of academic middle managers (AMMs) in the planning and implementation of curriculum change in private higher education institutions (PHEIs) in Botswana. Drawing from various sources of literature and theoretical underpinnings, the study described how AMMs enact their role in curriculum change. A quantitative approach that used a structured questionnaire for data collection was used in the study. Results of the study showed that AMMs face numerous challenges during curriculum change which have a negative impact on their role. These challenges include lack of authority, lack of detailed job descriptions, work overloads among others. Results further showed that the following variables namely curriculum leadership, AMM job requirements, AMMs role enablers, work experience, educational levels of AMMs are important predictors of effective AMMs role in the planning and implementation of curriculum change in PHEIs and hence need to be optimized. It was also shown that gender, age, department size do not have a significant effect on the effectiveness of AMMs in their role in curriculum change while level of education and years of experience have a significant effect. Based on the results, a model for enhancing the effectiveness of AMM role in the planning and implementation of curriculum change was proposed.

A COMPUTERIZED IDENTIFICATION SYSTEM FOR VERB SORTING AND ARRANGEMENT IN A NATURAL LANGUAGE: CASE STUDY OF THE NIGERIAN YORUBA LANGUAGE (Published)
The context of Understanding has continued to be a major attraction to researchers in Natural Language Processing. This is built on the theory that language can be used effectively if it is understood and can be analyzed and as such, most Natural Language Processing research tend towards the belief that the human brain has a section dedicated for language analysis and understanding therefore, human ambiguity which, remains the major difference between natural and computer languages, can be modeled using appropriate man machine modeling tools since programming languages are designed to be unambiguous, that is, they can be defined by a grammar that produces a unique parse for each sentence in the language. The paper evaluates the classification process for a Natural language ‘the Yoruba language’ and presents a new method by which the language can be transformed into a computer understandable language using its morphological identification framework. Result shows that the approach is admissibly in line with known benchmarks. The paper recommends that non tonal language can also be experimented using the defined approach.
The study examined the prevalence of HIV/AIDS in the Techiman Municipality of Ghana. We used model with standard incidence to analyze, model and predict the prevalence of HIV/AIDS in the Techiman Municipality. The model has two equilibrium states: the disease-free equilibrium and the endemic equilibrium states respectively. The stability condition of each equilibrium point is discussed. The basic reproductive number ( ) of HIV/AIDS infection is estimated to be in the Techiman Municipality. Our work shows that the reproductive number of HIV/AIDS infection in the Techiman Municipality is less than 1( ) and therefore concluded that the disease is not epidemic in the municipality as described by the GAC in their study in 2005. We recommend that education on HIV/AIDS in the municipality should be intensified so as to decrease the rate of transmission of HIV in the municipality.
TIME SERIES ANALYSIS FOR MODELING AND DETECTING SEASONALITY PATTERN OF AUTO-CRASH CASES RECORDED AT FEDERAL ROAD SAFETY COMMISSION, OSUN SECTOR COMMAND (RS 111), OSOGBO (Published)
Motor accident is a major cause of mortality and disability in Nigeria, which
explains the reason for the establishment of Federal Road Safety Commission in 1988 to address
the carnage and maiming on the highways and roads. This paper employed Time Series statistical
tools to build model, and examine seasonality pattern of the number of cases of motor accident
recorded at the Federal Road Safety Commission, Osun Sector command using secondary data
collected from the record section of the command from 2006 to 2012. Autoregressive Integrated
Moving Average (ARIMA) depicts reduction in the recorded number of cases recorded. This result
was corroborated by Least Squares trend with quarterly decline of six (6) cases of motor accident.
The seasonal pattern clearly portrayed quarter four (October, November, and December) as the
season with high prevalence of motor accident. It was finally concluded that the Federal Road
Safety Commission has been performing to expectation in the manner it discharges her duties by
adjuring from the results of the analyses
This work applied Generalized Autoregressive Conditional Heteroskedasticity (GARCH) approach to modelling volatility in Rwanda Exchange rate returns. The Autoregressive (AR) model with GARCH errors was fitted to the daily exchange rate returns using Quasi-Maximum Likelihood Estimation (Q-MLE) method to get the current volatility. Asymptotic consistency and asymptotic normality of estimated parameters were given. Akaike Information criterion was used for appropriate GARCH model selection while Jarque Bera test used for normality testing revealed that both returns and residuals have fat tails behaviour. It was shown that the estimated model fits Rwanda exchange rate returns data well.
Production planning is the backbone of any manufacturing operation, and its main objective is to determine the quantity of products to be produced and inventory level to be carried from one period to the other, with the objective of minimizing the total costs of production and the annual inventory, while at the same time meeting the customers’ demand. A mathematical model was developed for a multi-product problem using Dynamic Programming approach and the solution procedure proposed by Wagner and Whitin was adopted. The model is very useful in solving a problem with multi-stage problem, a particular situation in which there is appreciable variation in average periodic demand and availability of raw materials among the different periods. It also stipulates the minimum quantities of the product to produce per period and the corresponding inventory levels such that total production cost is minimized over the planning periods
