Author:Gbadamosi, SA; Hancke, GP; Abu-Mahfouz, Adnan MIDate:Nov 2022In dense, interference-prone 5G narrowband Internet of Things (NB-IoT) networks, device-to-device (D2D) communication can reduce the network bottleneck. We propose an interference-avoidance resource allocation for D2D-enabled 5G NB-IoT systems ...Read more
Author:Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, Ntsibane SDate:Sep 2009Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in WMNs. In this paper, we present a dynamic power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs (UCGs). Second, each ...Read more
Author:Govender, P; Couling, VWDate:Sep 2010An adapted Michelson interferometric technique was used to measure strain induced birefringence in perspex. The birefringence was then used to determine the Kerr constant in perspex. The result obtained is compared to a colarimetric result ...Read more

Author:Gaigher, JLDate:1977This report deals with the reactivity of mineral matter prepared from coal by the radio-frequency oxidation method, with the using X-ray diffraction to detect mineral phase changes, and possible react ion mechanisms.Read more
Author:Gaigher, JLDate:1976The mineral matter factors for some coal product samples determined by the method of radio--frequency oxidation, compared with results from an earlier survey (Technical Memorandum No021 of 1971), appear to have an acceptable precision.Read more
Author:Meintjies, AADate:1967A preliminary study was made of the application of pyrolysis-gas chromatography to coal dust. A correlation between the explosibility index of a coal and the nature of its volatile matter would prove useful.Read more
Author:Meintjies, AA; Van Der Berg, FDate:1968The object of this investigation was to determine whether a correlation could be found between the known explosive properties of coal dusts and the nature, quantity and temperature dependence of volatile matter formation.Read more
Author:Sevenster, PG; Steenkamp, JHDate:1967In this report an account is given of a new technique developed at the Fuel Research Institute whereby the methane evolved from a coal sample is automatically measured and analyzed. The method utilizes a gas detector of high sensitivity to ...Read more
Author:Sevenster, PG; Joubert, JHDate:1967One of the research projects undertaken to establish the cause of the apparent inactivity of South African coal dusts when subjected to the explosibility tests designed by the U.S.B.M. was to study the influence of methane content of the coal ...Read more
