This prototype project is designed to monitor a traffic light controlled intersection by using a camera, whenever a vehicle breaks the traffic rules the camera takes a snap shot. Cameras are devices that, when linked to the signal controller, automatically photograph vehicles that enters the intersection after the onset of the red light. Typically offending drivers enter the intersection 12seconds after the onset of the red and most cameras are set to start photographing the drivers upon the 2esecond after red. Red light cameras are used to improve safety at traffic-light controlled intersections. Typically, the cameras are installed at high-accident intersections or0at0locations where drivers are likely to disobey traffic signals. Using sensors, the vehicles are monitored with reference to the traffic light indicators. A proximity induction sensor always on and if a vehicle exceeds the control line on the road, after RED light is on, the camera switches on and the images are stored in Windows Media file. The authority can view the images from a remote computer. 2017-06-01T00:00:00Z Mangwaya, Gehas Gerald https://cris.library.msu.ac.zw//handle/11408/2455 Title: Detection of limestone deposits in the Nyanda mountain range, Masvingo, using ground magnetic geophysical survey. Authors: Chipokore, Simbarashe Abstract: Geophysical survey techniques have successfully been applied to near-surface limestone detection in karstic terrains. A magnetic geophysical survey to delineate the karstic structure of the Nyanda Mountains, Masvingo, was carried out in the interest of mapping out limestone deposits required for cement production. The magnetic-total-field-anomaly maps helped reveal the metamorphic and sedimentary units in the study area. Although only part of the mountain range was surveyed for this project, the results suggested that the buried limestone units had an undulating karstic topography including a probable pinnacle structure. A synthetic modelling study was carried out, and it validated the reliability of the results. Finally, the findings indicated that the geophysical survey techniques used here were successful in detecting limestone deposits through the rather vertical terrain difficult to traverse carrying ground penetrating radar or resistivity instruments, which are usually employed to explore limestone deposits. The magnetic survey was also cost effective with respect to the cost demands of the other possible geophysical techniques. The study results were digitised from GEM-systems magnetic data loggers by Oasis Montaj and was exported to mapping software, MapInfo. To access the geodatabase the user needs to have ArcGIS 8.3 or later and basic EXCELL software. 2014-05-01T00:00:00Z Chipokore, Simbarashe
