    Analyzing the use of ICT for professional development among secondary school teachers in Tanzania
    (Semantic Scholar, 2016) Mwifunyi, Rukia; Kibinda, Nyaura
    Teachers' Professional Development refers to a variety of activities both formal and informal, which is designed for a personal and professional growth for teachers. The advancement of technology has been recognized to play a valuable role in developing and improving the teaching and learning situations. This study, aims at analyzing the use of ICT in Teachers' professional among the Tanzanian Secondary School teachers. Data used in this study, were collected through a field data collection. A total of 139 questionnaires were filled and analyzed by using SPSS package. Multiple regression models were used for analysis. Factors which were included in the model explain the variability in teaching professional development by 43.30% as R square = 0.433. F value was equal to 3.381 and p-value = 0.008 implies that the overall model is reasonable at 5% level of significance. This model is statistically fit to check the use of ICT in teaching professional development.

    Fault detection and monitoring in secondary electric distribution network based on distributed processing
    (IEEE, 2018) Mnyanghwalo, Daudi; Kawambwa, Shamte; Mwifunyi, Rukia; Gilbert, Gilbert M.; Makota, David; Mvungi, Nerey
    Inefficient fault management is one of the major challenges facing the only electrical utility company, the Tanzania Electric Supply Company to ensure safe, reliable and efficient power supply in the electrical Secondary Distribution Network (SDN). Currently, faults management processes from detection to clearance are performed manually and therefore inefficient. There have been initiatives by utility electrical company to automate faults clearance in the transmission and primary distribution parts of the network using SCADA and DMS, which are largely centralized. However, due to the complexity and ubiquitous nature of the SDN, automation is still challenging. This study proposes a distributed processing architecture for automatic faults detection and monitoring for the Tanzanian electrical SDN as it has been identified to fit well in network monitoring compared to the centralized approach. The proposed architecture consists of remote sensing units, distributed central processing units, central monitoring and communication platform. The architecture was implemented and tested in live network at UDSM-Kijitonyama Campus and found to work well.
