  • Ferreira, T.M; Billingham, P.A (1973)
    The difference between sound and noise varies from one human being to another. Noise, then, is simply unwanted sound and to understand how it can be combatted we must know more about its nature. A guide of acceptable levels ...
  • Chamber of Mines, South Africa (Chamber of Mines Services, 1978)
    In simple terms Fanakalo means 'like this'. Fanakalo originated in the sugar industry of KwaZulu Natal as a result of Indians trying to learn English and Zulu at the same time. The language spread across the boarders of ...
  • De Beer, Morris; Horak, E (1987)
    Most of the structural failures in road pavements are in one way or another associated with excess water trapped within the pavement structure owing to poor drainage. The combined effect of traffic loading and trapped water ...
  • Cooper, Antony K; van Rooyen, MH; Clarke, DG; Liebenberg, EC (CSIR, 1987-09)
    Geographically referenced (geo-referenced) information consists of all information that refers to the man-environment system and that can be localized in space and time. The basic entity of geo-referenced information is ...
  • De Beer, Morris; Kleyn, EG; Savage, PF (1988)
    This paper deals with the development of a universal classification system for flexible pavements with thin surfacings. This classification is based on the results obtained with the Dynamic Cone Penetrometer (DCP) utilising ...
  • Cooper, Antony K (Computer Society of South Africa, 1988)
    Geographical information consists of non-spatial information (alphanumeric) and spatial information (vector and raster), the relationships between the non-spatial information and the spatial information, as well as the ...
  • Cooper, Antony K (CSIR, 1988-02)
    This paper describes a suite of programs that simulates the lighting effects of the sun or moon on the earth's surface. A digital terrain model (DTM) is typically a two-dimensional regular tessellation of some measured ...
  • Cooper, Antony K (1989-04)
    Geographically referenced (geo-referenced) information consists of all information that refers to the human-environment system and that can be localized in space and time. This includes cadastral, topographic, hydrographic ...
  • Olivier, JJ; Greenwood, PH; Cooper, Antony K; McPherson, DR; Engelbrecht, R (ASPRS Publications, 1990)
    Owing to the complex, inter-disciplinary nature of geographical information systems (GIS), and to the wide variety of commercial GIS software available, considerable effort is needed to select software and hardware which ...
  • Lacante, SC; De Beer, Morris; Horak, E (1991)
    Many years of experience exist in South Africa on the use and interpretation of Benkelman beam type of road surface deflection measurements with the Road Surface Deflectometer (RSD), as well as depth deflection measurements ...
  • De Beer, Morris; Kleyn, EG; Wolff, H; Otte, JR (1991)
    This paper summarises the full scale accelerated research done during the past six years with the Heavy Vehicle Simulator (HVS) belonging to the Roads Branch of the Transvaal Provincial Administration (TPA). The research ...
  • Balmaceda, P; De Beer, Morris (1992)
    A methodology for evaluating the condition of jointed portland cement concrete pavements (JCP) by non-destructive deflection testing was recently applied on the National Route 4 (N4) between Middelburg and Witbank. A set ...
  • De Beer, Morris (1992)
    This paper summarises some of the main effects of non-linear, ie stress stiffening (in this case) behaviour of resilient elastic moduli of typical granular base pavement structures on the calculated deflection basin. The ...
  • McGillivray, R (Learned Information Ltd, 1993)
    Local information distribution in electronic form in South Africa is a new and growing industry. Research shows that in any country the needs of users of information are largely for local information and to a lesser extent ...
  • Semmelink, CJ; De Beer, Morris (1993)
    The paper briefly describes the K-mould and the dynamic loading and data acquisition system that was developed for the Division of Roads and Transport Technology (Transportek) K-mould. The loading system allows for the ...
  • Wolff, H; Visser, AT; De Beer, Morris (1993)
    A brief review of the theory of material behavour is given as background to a discussion on the behaviour of granular materials as determined, from accurate measurments of elastic and plastic strains under fullscale Heavy ...
  • Sanders, P; Van Huyssteen, S; De Beer, Morris; Venter, JH (1993)
    Some important aspects relating to structural damage caused by abnormally loaded vehicles on a range of typical South African pavement types are described. A summary of a detailed case study is given as is the determination ...
  • Evans, ED (Learned Information (Europe) Ltd, 1993-08)
    The new South Africa needs information and the CSIR has enabled end-users to search international and local database using an intelligent gateway to provide easy, affordable access to all the well-known hosts. All terminals, ...
  • Watson, AG; Barnes, RJ (Plenum Publishing Corporation, 1995-07)
    Three problem-dependent meanings for engineering ''extremes'' are motivated, established, and translated into formal geostatistical (model-based) criteria for designing infill sample networks. (I) Locate an area within the ...
  • Grundlingh, M; Rossouw, M (Bureau for Scientific Publishers, 1995-07)
    The enlargement of surface wave height in the Agulhas Current, caused by waves propagating in the opposite direction to the current, is well known for its danger to large vessels traversing the Cape route. Occurrence ...
