Abstract: Local e-government is the application of appropriate Information and Communication Technologies (ICTs) at the local government level to improve the administration and provision of local government services to local residents. The purpose of this conceptual framework is to explore the determinants influencing the intention to adopt and use local e-government services. This research will also to seek to differentiate between informational and transactional local e-government services and to examine factors influencing local residents to desire to use either transactional or informational local e-government or both. Factors such as Perceived Usefulness, Perceived Ease of Use, Computer Self-efficacy, Perceived Service Quality, Demographic Factors, Trust in Local Government, Trust in the Internet and Perceived Risk will be investigated. The Technology Acceptance Model (TAM) will be used as the theoretical framework for this study. A well-structured research questionnaire instrument would be developed and administered to 1,000 potential respondents at four different local government jurisdictions in Ghana. The data gathered would be captured and analyzed with SPSS while a further detailed analysis would be conducted using the Structural Equation Modeling (SEM) method.

Abstract: The explosive growth of resources stored in various forms and transmitted over the internet has necessitated researches into information retrieval technologies. The major information retrieval mechanisms commonly employed include vector space model, Boolean model, Fuzzy Set model, and probabilistic retrieval model. These models are used to find similarities between the query and the documents to retrieve documents that reflect the query. These approaches are based on key-word, which uses lists of keywords to describe the information content. In this paper, a survey of these models is provided in order to understand their working mechanisms and shortcomings. This understanding is vital as it facilitates the choice of an information retrieval technique, based on the underlying requirements. The results of this survey revealed that the current information retrieval models fall short of the expectations in one way or the other. As such, they are not ideal for high precision information retrieval applications.

Abstract: Mobile Ad Hoc Networks (MANETs) are wireless networks formed by several nodes communicating on a peer-to-peer basis without being connected to any fixed infrastructure. These nodes could be laptop computers, personal digital assistants, mobile phones or sensors dispersed in an area to measure certain data and send the information to a larger node. Where a source node and a destination node are not within direct range, they communicate through multi-hop routing, i.e. nodes in between them relay messages between source and destination. The routing protocol plays a key role in finding and maintaining the route in MANETs. Routing protocol can be a uni-path and multi-path. A multipath routing protocol is designed to increase the reliability in MANET. This research work focuses on Quality of Service (QoS) based evolution of multipath routing protocol. For this purpose, diverse type of simulation scenarios is designed to find the impact of mobility, increasing the number of nodes and pause time in MANETs. The results revealed that multipath routing protocol has comparatively less delay (percentage decrease of 81.52%). While unipath routing protocols have less packet drop ratio (percentage decrease of 47.78%) and routing overhead (percentage decrease of 99.30%).
