Lifetime improved WSN using enhanced-LEACH and angle sector-based energy-aware TDMA scheduling
(Cogent Engineering, 2020-07-20)
Network lifetime remains as a significant requirement in Wireless Sensor
Network (WSN) exploited to prolong network processing. Deployment of low power
sensor nodes in WSN is essential to utilize the energy efficiently. ...
Cluster based wireless sensor network for forests environmental monitoring
(International Journal of Advanced Technology and Engineering Exploration, 2020-02)
Monitoring the forest’s weather has been essential to living things over the years. Currently, there is a shortage of information on real-time temporal and spatial environmental conditions of the forest that drive forest ...

(Modern Education and Computer Science Press, 2020-04)
There is a wide collection of invaluable varie-ties of ornamental plants and flowers available for sale by vendors in Arusha city contributing to local employment, and food security. Horticulture in Tanzania is dominated ...
Mathematical Model for Optimal Control of Soil-Transmitted Helminth Infection
(Hindawi, 2020-08-01)
In this paper, we study the dynamics of soil-transmitted helminth infection. We formulate and analyse a deterministic compartmental model using nonlinear differential equations. The basic reproduction number is obtained ...
Identification of the Time-Dependent Point Source in a System of two Coupled Two Dimension Diffusion-Advection-Reaction Equations: Application to Groundwater Pollution Source Identification
(Global Journal of Pure and Applied Mathematics, 2020)
This paper addresses the inverse source problem in a system of two-dimension
advection-dispersion reaction equation with an emphasis on groundwater pollution
source identification. We develop an inverse source problem ...
Multi-Criteria Decision Making and Numerical Optimization Approaches for Optimizing Water Loss Management Strategies in Water Distribution System A case of Urban Water Supply and Sanitation Authorities in Tanzania
(Modern education and computer science press, 2019-11)
Water loss in water distribution systems (WDS) is a serious problem in Tanzania and the third world countries
at large. A lot of water is lost on its way before reaching the consumers. This causes a shortage of water ...
MHD Arterial Blood Flow and Mass Transfer under the Presence of Stenosis, Body Acceleration and Chemical Reaction: A Case of Magnetic Therapy
(Journal of Mathematics and Informatics, 2020-02-17)
A mathematical model has been developed and used to study pulsatile blood
flow and mass transfer through a stenosed artery in the presence of body acceleration and
magnetic fields. An explicit Finite Difference Method ...
Backward Bifurcation and Optimal Control Analysis of a Trypanosoma brucei rhodesiense Model
(MDPI, 2019-10-14)
In this paper, a mathematical model for the transmission dynamics of Trypanosoma brucei rhodesiense that incorporates three species—namely, human, animal and vector—is formulated and analyzed. Two controls representing ...
Towards Personalised Learning in Higher Learning Institutions in Tanzania
(2024-12)
This study examines the challenges and students’ perceptions of adopting and implementing e-learning in Tanzanian
universities to facilitate the shift towards personalised learning. Although technology and online courses ...
‘Mind the Gap’: Reconnecting Local Actions and Multi-Level Policies to Bridge the Governance Gap. An Example of Soil Erosion Action from East Africa
(MDPI, 2020-09-25)
Achieving change to address soil erosion has been a global yet elusive goal for decades. Efforts to implement effective solutions have often fallen short due to a lack of sustained, context-appropriate and multi-disciplinary ...
