Abstract:Artificial neural networks (ANN) have received a great deal of attention in many fields of engineering and science. Inspired by the study of brain architecture, ANNs represent a class of nonlinear models capable of learning from data. ANNs have been applied in many areas where statistical methods are traditionally employed. They have been used in pattern recognition, classification, prediction and process control. The purpose of this research is to compare ANNs and Box-Jenkins ARIMA time series models to forecast Naira/Dollars exchange rates. This research described an empirical study of modelling and forecasting time series data of Exchange rate of Nigeria Naira (N) to the USD ($). The Box-Jenkins ARIMA and Artificial Neural Network (ANN) methodologies were used for forecasting the monthly data collected from January 1991 to June 2018 through CBN website www.cbn.gov.ng. The diagnostic checking has shown that ARIMA (2, 1, 3) is appropriate. ANN with two time delay and one hidden neuron is also shown to be the best architecture trained for the data. However, the results Neural Networks trained by the Levenberg-Marquardt (LM) provides better forecasts than ARIMA model as it gives smaller mean square error.

Abstract:Modern Information Communication Technology is a significant strategic tool for improving public sector service delivery, offering benefits of greater efficiencies and effectiveness in government operations, improved communication and coordination across organisational boundaries and levels of government, and greater transparency and accountability in government functions. This study sought to determine the perceived benefits impelling the use of ICT in improving public service delivery. The study also sought to establish the extent to which ICT facilities acquired are applied in improving public service delivery. The target population was 800 employees from the County government departments. Stratified random sampling was used, based on the current departments the strata were formed. Respondents were identified by simple random sampling. The sample size was 89 respondents. The primary data was collected using questionnaires. The data was processed and analyzed using descriptive statistics including frequencies, percentage, mean, and standard deviation. Data was presented using tables, pie charts and bar charts. Correlation analysis was employed to determine whether there existed a relationship or association between the variables. Multiple linear regression model was used to test the relationship between independent variables and dependent variables of the study. The results of correlation and regression analysis showed that perceived benefits of ICT and ICT facilities had a positive and significant effect on service delivery at the Machakos County Government. Based on this finding the study concluded that that information communication technology played a significant role in ensuring delivery of quality services in public sector. The study concluded that ICT facilities made information sharing and activities coordination simpler, effective and efficient between various departments and between employees. This efficient flow of information and communication ensured that turnaround time was reduced, employees moved less and service delivery was improved. The study recommended that to ensure high quality service delivery, all the departmental heads needed to communicate the benefits of ICT knowledge in carrying the county responsibilities to all the employees in their department to influence them to acquire ICT skills. The study recommended that top leadership at the county government of Machakos needed to ensure that all the necessary ICT facilities were made available to employees at various levels to facilitate their service delivery.

Abstract:The researcher has come up with an idea on focusing the study in developing a software/ application entitled University e-bulletin that will allow the students to view the latest and upcoming events, gatherings, and activities in the College of Computer Studies through their android phones. The students can also make their own announcement through this application if they wish to. Documentation provided hereto are the methods of research and data gathering techniques used in the study to come up with reliable and useful data needed for the development of the study. A model is recommended as a theoretical framework for the development of the study. This model is called Rapid Application Development presented as a structure that can hold or support a theory of research study of a software development process. The software was evaluated using ISO 9126 Software Quality standard and based on the result the system is compliant to the ISO Software Quality Standard.
