Fuel cells are controlled by black box control systems which does not allow for the user to understand the proprietary control algorithms employed. Little feedback can be understood from the control system and this leads to the blind use of the proton exchange membrane fuel cells which in turn could lead to cell deterioration and failure. Understanding the important factors influencing proton exchange...
This paper outlines the design strategy for the University of Johannesburg's (UJ's) hybrid vehicle entry into the South African Solar Challenge (SASC) 2010. The SASC is a biennial event focused on alternative energies and showcasing various automotive technologies. The SASC is broken up into different classes; UJ entered in the Greenfleet Technology class. This paper presents the design principles...
This paper introduces the first available tool flow for Dynamic Partial Reconfiguration on the Spartan-6 family. In addition, the paper proposes a new configuration method called Fast Start-up targeting modern FPGA architectures, where the FPGA is configured in two-steps, instead of using a single (monolithic) full device configuration. In this novel approach, only the timing-critical modules are...
The ranger micro-UUV from Nekton Research has been deployed successfully in various multi-agent mission demonstrations, including formation flying to map a salinity front and adaptive cooperation to localize the origins of test plumes. The low cost and simplicity of using the 5 kg Rangers make possible multiagent missions and algorithm testing that is beyond the economic reach of alternative UUVs...
