Development of an intelligent tracking system for monitoring rhinos and elephants: A case study of Ngorongoro conservation area
(NM-AIST, 2021-06) Massawe, Erick
Events such as poaching, accidents, unexpected adverse health events (e.g., heart problems, seizures, heart stroke, dizziness, breathing problems, bleeding and broken bones) have adverse impact on animals’ health. Many of such events, if known to someone in a position to assist the animal, can be avoided, minimized or ameliorated. Unfortunately, many events occur in a manner in which assistance is unavailable or provided too late. In regard to this, measures needed include improving systems and methods for avoiding or reducing the impact of such adverse events. The study developed an intelligent real-time tracking system for monitoring rhinos and elephant. It was guided by four specific objectives: reviewing and analyzing the existing systems for tracking animals and proposing new more intelligent systems, designing of smart sensing system for animal emotions recognition, developing computational models’ analysis of wildlife tracking system for optimality, and developing an intelligent wildlife collar information management system using mobile application. The first objective was accomplished by conducting a cross-sectional study, and one-time data collection at Ngorongoro Conservation Area, Tanzania. The second objective was completed by designing a modern smart sensing animal collar belt that can recognize animal emotions. The third objective was performed by attenuation models-based analysis of wildlife tracking system for optimality. And the fourth objective was accomplished by developing a mobile application that collects periodical sensor output responses from tracked elephant/rhino with their GPS locations. All developed solutions were promising and can be utilized on improvement of the current existing ant-poaching system. The solutions can be considered as a proof of concept, which needs to be developed further for use in final product.
Fuel Adulteration in Tanzania and its Consequencies: An Overview
(Rjeas, 2013) Massawe, Erick; Kilavo, Hassan; Sam, Anael
Adulteration of petrol and diesel fuel with kerosene is very common in Tanzania. It increases the tailpipe emissions of harmful pollutants from vehicles. These leads to this study, which tends to show the rate of emission of CO (carbon II oxide) and PM (Particulate matters) from engines when they are run on adulterated fuel. Petroleum products are essential inputs needed in economic activities, hence a necessity for the economy of any Country. Adulteration of petroleum products especially petrol (motor gasoline) and diesel (high speed diesel (HSD)), has become a serious problem. Expensive consumer products are often adulterated by integrating with cheaper low quality materials having similar physical and chemical properties. Kerosene is the most important domestic fuel for economically weaker sections of society and hence is heavily subsidized. The large differences in the prices of petrol, diesel and kerosene, the easy availability of kerosene and the fact that it is miscible in petrol and diesel, make the unhealthy and unethical practice of adulteration of petrol and diesel a very plausible proposition. Effects of adulteration on the environment and on human health were discussed and possible solutions to combat adulteration of fuel were highlighted.
An intelligent real-time wireless sensor network tracking system for monitoring rhinos and elephants in Tanzania national parks: A review
(International Journal of Advanced Smart Sensor Network Systems, 2017-10-04) Massawe, Erick; Michael, Kisangiri; Kaijage, Shubi; Seshaiyer, Padmanabhan
The advancement of wireless sensor networks yields a variety of wireless sensor network for wildlife tracking. One typical application for wireless sensor networks is in animal tracking and monitoring in wildlife environments. A significant number of studies have been done in tracking animals with sensor networks. However from the recent literature it is observed that there is no much study has been done on an intelligent real time sensor network that is capable to alerting the rangers an incidence of animal poaching before it happened. In this paper an intelligent wireless sensor system for tracking and monitoring rhinos and elephants is proposed.
