This thesis outlines the implementation and commissioning of a LabVIEW based, dual axis solar tracking system located within Murdoch University’s Renewable Energy Outdoor Test Area. An electrical system that is capable of supplying power to the solar tracking hardware and protecting it from the effects of overcurrent has been designed, installed and tested according to several Australian Standards including the AS3000 Wiring Rules. The testing of the electrical system proved that the installation was both safe and reliable and as such it was connected to the existing Murdoch University ele

Detection of an underwater target with active sonar in shallow waters such as the Baltic sea is a big challenge.

These false targets are unwanted and a real target might benefit from these miss-classifications in terms of remaining undetected. It is especial
