The use of VR during testing of fatigue in air traffic controllers
Air traffic control (ATC) aims to transport aeroplanes safely and efficiently through the airspace. This job requires the workers to stay alert and be constantly monitoring the traffic to avoid catastrophic incidents. It is therefore very important to track and manage fatigue among air traffic …

The reproductive health effects of along term DDT exposure on malaria vector control workers in Northern Province, South Africa
… countries including South Africa for the control of malaria vectors, have been shown to be endocrine disruptors in vitro and in vivo. The study hypothesis was that male vector control workers highly exposed to DDT in the past should demonstrate clinically significant exposure-related …

Computer simulation of a large-scale non-linear feedback control system
… Compensation Network. This network is a feedback control system that filters out the effects of surface ship motion on a weapon's response to commands from the ship's fire control center. The network includes a number of non-standard elements that prevent mathematical prediction of its closed-loop …
