  • KernTune: Self-tuning Linux kernel performance using support vector machines 

    Yi, Long; Connan, James (Association for Computing Machinery, 2007)
    Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
  • Kiara: an open source SIP system to support Deaf telephony 

    Yi, Long; Tucker, William David (Telkom, 2008)
    This paper describes Kiara, an open source SIPbased communication system that provides the building blocks to enable Deaf relay services. We have implemented a prototype that provides real-time text, voice and video to a ...
  • KPD 0629–0016, a slowly pulsating hot subdwarf star 

    Koen, Chris; Green, E.M (Oxford University Press, 2007)
    The results of nine CCD photometric observing runs on KPD 0629–0016 are presented. During six of the runs measurements were obtained alternately through B and V filters. Four periodicities, for which there is good agreement ...
  • Leptophytum foveatum Chamberlain & Keats (Rhodophyta, Corallinales) retaliates against overgrowth by other encrusting algae 

    Keats, Derek; Maneveldt, Gavin (Elsevier, 1994)
    The encrusting coralline alga, Leptophytum foveatum, is the most abundant crustose alga in the lower eulittoral zone at Yzerfontein and other exposed sites on the West Coast of South Africa. The surface of this species is ...
  • Life at the margins of the continents: an examination of the intertidal marine life of the south Western Cape 

    Maneveldt, Gavin (Field Guides Association of Southern Africa, 2010)
    Imagine surviving in an environment that is neither truly marine nor truly terrestrial. That area just beyond the low-water mark of neap tides along the seashore is an example of just such an environment. The organisms ...
  • Linking multi-epoch CCD photometry of partially overlapping fields 

    Koen, Chris (Oxford University Press, 2013)
    A common problem in CCD photometry is to combine measurements obtained at different epochs. This is especially challenging if the fields only overlap partially, and are sparse, so that not all calibrating stars are ...
  • Local ownership, exercise of ownership and moving from passive to active entitlement: a practice-led inquiry on a rural community network 

    Rey-Moreno, Carlos; Sabiescu, Amalia; Siya, Masbulele Jay; Tucker, William David (CCIRDT, 2015)
    In this paper, we aim to shed light on local ownership from a double practical and theoretical perspective, and examine its meaning as well as the factors that are bound to influence its development in community based ...
  • Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work 

    Bours, M.C.P.; Kilkenny, David (Oxford University Press, 2016)
    We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includes 67 close binaries, both detached and ...
  • Low-Cost feedstock conversion to biodiesel via ultrasound technology 

    Babajide, Omotola; Leslie, Petrik; Amigun, Bamikole; Ameer, Farouk (MDPI, 2009)
    Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable ...
  • Making a community network legal within the South African regulatory framework 

    Rey-Moreno, Carlos; Tucker, William David; Cull, Domonic; Blom, R. (ACM, 2015)
    Community networks often operate at the fringe of legality with respect to spectrum, network infrastructure and providing services. We have been involved with such a network in a rural community, and together with them, ...
  • Mapping and characterisation of the sorghum cell suspension culture secretome 

    Ngara, Rudo; Ndimba, Bongani K. (Academic Journals, 2011)
    Here we reported the first secretomic study of sorghum (Sorghum bicolor), a naturally drought tolerant cereal crop. In this study, we used a gel-based proteomic approach in combination with mass spectrometry to separate ...
  • Maternal mortality in Burkina Faso: a method from population census 2006 

    Lougue, Siaka; Appunni, Sathiya Susuman; Bonkoungou, Zakaliyat (Tehran University of Medical Sciences, 2013)
    Background: Estimating maternal mortality level is constantly challenging researchers and planners both in rich and poor countries. In developing countries, particularly in Burkina Faso where the registration system is not ...
