Accessibility and TB patient satisfaction in Nigeria.

Nigeria ranks first in Africa and sixth among countries with a high Tuberculosis burden globally. The increasing incidence of drug resistance following poor treatment adherence among drug-susceptible TB (DS-TB) patients necessitates reviewing TB services in Nigeria. This study explored accessibility and patient-reported experiences in newly established TB treatment facilities.

Recycling of aquaculture wastewater using charcoal based constructed wetlands.

The competitive demand for water makes it a scarce resource for agricultural use. This necessitates wastewater reuse for irrigation and any other agricultural purpose, especially in developing countries where treatment of wastewaters is not a priority. The aim of this study was to evaluate the performance of a charcoal-based constructed wetland (CBCW) in treating aquaculture wastewater.

Pose Estimation of a Mobile Robot Based on Fusion of IMU Data and Vision Data Using an Extended Kalman Filter.

Using a single sensor to determine the pose estimation of a device cannot give accurate results. This paper presents a fusion of an inertial sensor of six degrees of freedom (6-DoF) which comprises the 3-axis of an accelerometer and the 3-axis of a gyroscope, and a vision to determine a low-cost and accurate position for an autonomous mobile robot. For vision, a monocular vision-based object detection algorithm speeded-up robust feature (SURF) and random sample consensus (RANSAC) algorithms were integrated and used to recognize a sample object in several images taken.
