ABSTRACT Theses and dissertations are among the most important sources of valid detailed information on a particular subject on which researchers conduct widespread research work. This study aimed at developing and evaluating an online electronic theses and dissertations system. The University of Dodoma was used as a case study for this dissertation. A mixed approach data collection method was used effectively in this study. Several literatures were reviewed so as to identify challenges that ...
ABSTRACT This research investigated the impact of network topologies on the performance of OpenFlow protocol. OpenFlow Protocol is a southbound protocol over Secure Socket Layer (SSL) in Software Defined Networking (SDN). SDN architecture separates the intelligence (decision making) part (control plane) of network devices from forwarding capability (data plane). OpenFlow protocol is the communication protocol for exchanging control messages between control plane and data plane. The research i...
ABSTRACT The potentials of Saw dust, Rice husk and Groundnut shells were investigated for bioethanol production. The substrates were pretreated using 2%, 4%, 6% and 8% solution of dilute H2SO4 and HCl. The pretreated substrates were thermally treated at 1050C in order to detoxify them. The pretreated substrates obtained using different concentrations of acids were fermented using Saccharomyces cerevisiae (Yeast). The results show that Rice husk treated with 4% H2SO4 (2.689%dryweight) has...
ABSTRACT The foundation of educational development of any country through all ages has been focusing on the quality basic education from which the primary school pupils’ academic performance is of greatest interest. Basing on its important, this study was conducted in order to develop a model for the primary school pupils’ academic performance in Tanzania. The study employed panel longitudinal research design. Secondary data that were used in the study were collected from the President�...
Abstract In this dissertation, we generate solutions to Einstein-Maxwell field equations devoted to neutral anisotropic stellar objects using linear equation of state. The field equations are transformed by adopting Bannerji and Durgapal transformation. We generated the solutions to Einstein field equations and obtain matter variables and gravitational potentials by using the general differential equation governing the model. In our model, isotropic results are regained as a special case. Th...
ABSTRACT Software-Defined Network (SDN) is a new and booming network paradigm that promises to improve network performance. This is achieved by the separation of the control plane and the data plane. The traditional network faced a lot of challenges particularly on how to improve network performance, manual configurations of the network devices, and many more others. SDN overcome all these challenges by introducing the SDN controller that controls the entire network. This research work studie...
Abstract The advancement of wireless and mobile technologies has given rise to the mobile government (m‐Government). A new channel of public service delivery using a mobile phone. In Tanzania, several m‐Government initiatives have been undertaken. Among these, some can be said to have succeeded while others are still struggling. The reasons for these variations are not known. This study aimed to capture the critical success factors (CSFs) for the adoption of m‐Government and propose a f...
ABSTRACT The aim of the study was to evaluate the service performance of Fund Management Information System (FuMIS) of Zanzibar Social Security Fund (ZSSF). The data were collected by using questionnaires, interviews, technical documentary reviews and system analysis when the system users interacted with the system. The study examined the level of users‟ satisfaction on data accessibility from the system, response time, usability of computer applications and the system interfaces, as well a...
ABSTRACT In this manuscript, a group acceptance sampling plan (GASP) is developed when the lifetime of the items follows odd generalized exponential log-logistic distribution (OGELLD), the multiple number of items as a group can be tested simultaneously in a tester. The design parameters such as the minimum group size and the acceptance number are derived when the consumer’s risk and the test termination time are specified. The operating characteristic (OC) function values are calculated (...
ABSTRACT With the increasing complexity of networks, Software Defined Networks have been developed to logically control all networking devices such as switches and bridges centrally through the use of software defined network controllers. Controllers include beacon, opendaylight, floodlight, pox, ryu and many more. Ryu SDN controller is one of the most popular python developed controller. Just as many other controllers’ Ryu may become a bottleneck since all other network controller controls...
ABSTRACT This study examined the modelling for maize prices using Autoregressive Integrated Moving Average (ARIMA) models so as to determine the most efficient and adequate model for analyzing the maize monthly prices at the Gairo market in Morogoro Region, Manyoni market in Singida Region and Kibaigwa market in Dodoma Region. The results indicate that ARIMA (1, 1, 4) model is the most adequate and efficient model for Gairo market, ARIMA (2, 1, 3) model is the most adequate and efficient mode...
ABSTRACT The study was aimed at developing a mobile phone service (SMS based) to be used to raise awareness among women about cervical cancer in United Republic of Tanzania. The study investigated and analyzed factors that hinder the use and implementation of mobile phone service to increase women awareness about cervical cancer. Furthermore, the study determines content that should be included in a mobile phone service to increase awareness about cervical cancer. The designed SMS based facil...
ABSTRACT Students’ dropout from completing courses in higher learning institutions is a prevailing problem in Tanzania as in other countries. The intensity of the problem varies from one institution to another. Several measures have been taken by the institutions so as to reduce the number of students’ dropout. In this study, a support vector machine model is developed and tested in the prediction of the students’ dropout to help reduce the number of students dropping out of studies by...
ABSTRACT The study deals with the analysis of a trend model on quarterly and yearly rainfall over Tanzania; conventionally and modern approach for the last 30 years. The yearly rainfall data from 1986 to 2016 was obtained from the Tanzania Meteorological Agency, Dar es Salaam, Tanzania. The rainfall data from representative stations in the homogeneous rainfall zones over Tanzania were analyzed for trends by graphical and statistical Methods. In order to achieve the main and specific objectiv...
ABSTRACT Tsetse flies, the vectors of trypanosomiasis, represent a threat to public health and economy in sub-Saharan Africa. Despite these concerns, information on temporal and spatial dynamics of tsetse and trypanosomes remain limited and may be a reason that control strategies are less effective. The current study assessed the temporal variation of the relative abundance of tsetse fly species and trypanosome prevalence in relation to climate in the Maasai Steppe of Tanzania in 2014-2015. ...
