Modelling the y-ray and radio light curves of the double pulsar system
(South African Institute of Physics, 2014)Guillemot et al. recently reported the discovery [1] of -ray pulsations from the 22.7 ms pulsar (pulsar A) in the famous double pulsar system J0737−3039A/B. The -ray light curve (LC) of pulsar A has two peaks separated ... -
Modernising underground compressed air DSM projects to reduce operating costs
(IEEE, 2014)Compressed air is an energy intensive utility that is frequently used in the deep level mining industry. Most compressed air networks are designed to ensure ample compressed air supply to consumers. This has created the ... -
Modified earliest decoding for random network codes
(IEEE, 2011)We present a practical, modified version of earliest decoding for random linear network coding networks. This decoding method has a lower complexity and decoding delay than traditional Gaussian elimination decoding schemes -
Monitoring gearbox oil viscosity by means of motor current signal analysis
(Univ of Huddersfield, 2017)A number of gearbox failures can be attributed to lubricant related problems. One measure of the condition of gearbox oil is its viscosity. In electrically powered systems, motor current signal analysis allows online ... -
Monitoring of the FSRQ PKS 1510-089 with H.E.S.S.
(PoS, 2017)The flat spectrum radio quasar (FSRQ) PKS 1510-089 (z=0.361) is known for its complex multiwavelength behavior. It has been monitored regularly at very high energy (VHE, E > 100GeV) gamma-rays with H.E.S.S. since its ... -
Monomers, polymers and cross-linked membranes for membrane fuel cells and electrolysis
(Electrochemical Society, 2011)This contribution comprises an overview about work in the development of ionomers/ionomer (blend) membranes for fuel cells. The topics include the development of novel sulfonated monomers and homo- and copolymers; the ... -
Moving households to cleaner energy through air quality offsets
(IEEE, 2018)Highest levels of exposure to polluted air in South Africa occur in low-income settlements where households burn solid fuels. The Department of Environmental Affairs has recently developed a legally enforceable mechanism ... -
MSP binaries as astrophysical laboratories
(Cambridge Univ Press, 2018)Follow-up of unidentified Fermi sources has expanded the number of known galactic-field “black widow” and “redback” millisecond pulsar binaries from four to nearly 30. Several systems observed by Chandra, XMM-Newton, Suzaku, ... -
Multi-wavelength observations of flaring blazars with ATOM and Fermi-LAT
(Sissa Medialab, 2017)The Automatic Telescope for Optical Monitoring is a 75cm optical telescope located at the H.E.S.S. site in Namibia. Since 2005, it monitors around 250 gamma-ray emitting AGN and has observed numerous blazar flares in several ... -
Multifaceted nanominerals and ultrafine particles in phosphogypsum: a by-product of coal cleaning rejects

Multivariable H∞ control for an active magnetic bearing flywheel system
(IET, 2010)A state-space model with uncertainties for an active magnetic bearing energy storage flywheel system (Fly-UPS) is developed. A multivariable robust H∞ controller for the Fly-UPS is then synthesised. Different weighting ... -
Multiwavelength analysis of four millisecond pulsars
(AIPC, 2011)Radio timing observations of millisecond pulsars (MSPs) in support of Fermi LAT observations of the gamma-ray sky enhance the sensitivity of high-energy pulsation searches. With contemporaneous ephemerides we have detected ... -
Multiwavelength modeling of the globular cluster Terzan 5
(ICRC, 2011)Diffuse X-ray emission has recently been detected from the globular cluster (GC) Terzan 5, extending out to ~2.5' from the cluster centre. This emission may arise from synchrotron radiation (SR) by energetic leptons being ... -
Multiwavelength polarization as a diagnostic of blazar physics
(Sissa Medialab, 2015)The nature of the high-energy emission in jet-dominated AGN (especially blazars) as well as the location and mode of acceleration of particles to ultra- relativistic energies are a matter of intensive debate. Both leptonic ... -
Multiwavelength signatures of shocks in relativistic jets
(HEASA, 2016)Mildly relativistic, oblique shocks are frequently invoked as possible sites of relativistic particle acceleration and production of strongly variable, polarized multi-wavelength emission from relativistic jet sources ... -
The mutualistic relationship between information systems and the humanities
(IBIMA, 2010)The paper explores the nature of the relationship between the study fields of Information Systems and the humanities. Although literature on Humanities Computing states in principle that there is a bidirectional, beneficial ... -
N-acetyl cysteine as therapeutic intervention in a “two-hit” model of maternal inflammation and post-natal methamphetamine exposure
(Elsevier, 2016)Schizophrenia is a severe neurodegenerative, pro- gressive degenerative illness, prevalent in 0.5−1% of the world population. It is causally associated with a genetic aspect as well as early-life environmental stress. ... -
Network resonance detection using harmonic active power
(IEEE, 2018)Resonances in electrical distribution systems can result in amplification of harmonics, which is undesirable in electrical networks. To avoid intrusive measurement techniques, in the majority of the cases network modeling ... -
Neural models for benchmarking of truck driver fuel economy performance
(INSTICC, 2019)The transport industry is a primary contributor towards emissions that impact climate change. Fuel economy is also of critical importance to the profitability of road freight transport operators. Empirical evidence identified ...
