Author:Mkhize, ZQP; De Beer, MorrisDate:Jul 2005This study introduces a new scale for weighing individual tyres of slow moving vehicles. The new technology is referred to as “Stress - In – Motion” or SIM and is statistically compared with an existing Weigh-In-Motion (WIM) scale (DAW 50) ...Read more
Author:Gee, EDate:Aug 1976Some of this data together with data as yet unpublished, were used in this present report with the object of obtaining a statistical assessment of the accuracy of the MSS (Mean Spindle Speed) at break technique.Read more
Author:Sivakumar, V; Bencherif, HDate:Apr 2006During some winters, zonal-mean configuration is dramatically disrupted with
polar stratospheric temperatures increasing rapidly with time, leading to a
poleward increase of zonal-mean temperature and, on occasion, a reversal of
zonal-mean ...Read more
Author:Oladipo, Folorunso; Hamam, R; Sadiku, R; Ray, Suprakas S; Adekoya, GJDate:Dec 2020In this study, an effective method has been described and adopted to quantify the diameter and length of graphene nanofiller. The experimentally measured graphene parameters were modelled by using the Weibull distribution. The fitted graphene ...Read more
Author:Botha, Natasha; Inglis, HM; Coetzer, R; Labuschagne, FJWJDate:Dec 2021Statistical design of experiments (DoE) aims to develop a near efficient design while minimising the number of experiments required. This is an optimal approach especially when there is a need to investigate multiple variables. DoE is a ...Read more
Author:Landman, WA; Engelbrecht, FA; Malherbe, Johan; Van der Merwe, JDate:Sep 2013Multi-decadal regional climate projections are assimilated into a statistical model in order to produce an ensemble of mid-summer maximum temperature for southern Africa. The statistical model uses atmospheric thickness fields (geopotential ...Read more
Author:Heyns, T; Godsill, SJ; De Villiers, JP; Heyns, PSDate:Feb 2012Condition-based maintenance is concerned with the collection and interpretation of data to support maintenance decisions. The non- intrusive nature of vibration data enables the monitoring of enclosed systems such as gearboxes. It remains a ...Read more
Author:Claassens, JDate:Nov 2009The author proposes an imitation system that uses relational interest points (RIPs) and Gaussian mixture models (GMMs) to characterize a behaviour. The system's structure is inspired by the Robot Programming by Demonstration (RDP) paradigm. ...Read more
Author:Kuun, C; Zimu, V; Barnard, E; Davel, MDate:Nov 2005We study the relationship between lexical tone and measured values of fundamental frequency for several word classes in isiZulu, based on objective measurements from recordings of three speakers. For nouns and adjectives, both in isolation ...Read more
Author:Ntaka, L; Musee, N; Das, Sonali; Muzenda, EDate:Aug 2013The widespread use of engineered nanomaterials (ENMs) in consumer products and industrial applications has raised concerns because of their potential impacts in the environmental systems. These concerns are due to dramatically increasing ...Read more
