Optimization of Hata Model based on Measurements Data using Least Square Method: A Case Study in Dar-es-Salaam – Tanzania
(International Journal of Computer Applications, 2014-09)
ABSTRACT
In this study, we present a measurement-based model for path loss prediction in three GSM service areas at 900 MHz .Modified Hata model for rural, suburban, and urban environments were derived in this study on ...
Survey on Intelligent Transport System (ITS) application for vehicle speed limit monitoring and accident reporting: A case study of Tanzania
(International Journal of Engineering And Computer Science, 2013-08)
Today’s transport system has evolved from horse driven carriages and paved roads to a more complex road transport system
made up of a variety of vehicles and other infrastructure, all put in place in order to support safe ...
Perona–Malik model with self-adjusting shape-defining constant
(Elsevier, 2018-09)
For decades, the Perona–Malik (PM) diffusion model has been receiving a considerable attention of scholars for its ability to restore detailed scenes. The model, despite its promising results, demands manual tuning of the ...
A Survey of Machine Learning Approaches and Techniques for Student Dropout Prediction
(Data Science Journal, 2019-04-17)
School dropout is absenteeism from school for no good reason for a continuous number of days. Addressing this challenge requires a thorough understanding of the underlying issues and effective planning for interventions. ...
Modeling and Stability Analysis for Measles Metapopulation Model with Vaccination
(Science Publishing Group, 2015-10-22)
In this paper, a metapopulation model is formulated as a system of ordinary differential equations to study the
impact of vaccination on the spread of measles. The disease-free equilibrium is computed and proved to be ...

serious issue in developing countries. On the other hand, machine learning techniques have gained much attention on addressing this problem. This paper, presents a thorough analysis of four supervised learning classifiers ...
Modeling the Dynamics of Rabies Transmission with Vaccination and Stability Analysis
(Science Publishing Group, 2015-10-09)
In this paper we formulate a deterministic mathematical model for the transmission dynamics of rabies in human
and animal within and around Addis Ababa, Ethiopia. Our model involves vaccination program for dog population. ...
Wildfire Monitoring and Detection System Using Wireless Sensor Network: A Case Study of Tanzania
(Scientific Research Publishing Inc, 2017-08-18)
This paper proposes a wildfire monitoring and detection system based on wireless
sensor network. This system detects fire by monitoring surrounding temperature,
humidity and smoke. Once fire is detected, a warning message ...
Implementation of a goal programming model for solid waste management: a case study of Dar es Salaam – Tanzania
(EDP Sciences, 2017)
Abstract – In this research article, the multi-objective optimization model for solid waste management problem is
solved by the goal programming method. The model has three objectives: total cost minimization, minimization ...
