  • Cardiovascular response to whole-body vibration on an automobile seat 
    Kat, Cor-Jacques; Jooste, Jacques Schalk; Grant, C.C. (Catharina Cornelia); Becker, Piet J.; Els, Pieter Schalk (Taylor and Francis, 2021)
    The study aim was to determine whether a relationship exists between the cardiovascular response, measured by HR and HRV and the magnitude of whole-body vibration. Cardiovascular response of sixty male participants in four ...
  • Challenges of integrated vehicle chassis control : some findings of the European project Eve 
    Ivanov, Valentin; Savitski, Dzmitry; Augsburg, Klaus; Els, Pieter Schalk; Kat, Cor-Jacques; Botha, Theunis R.; Dhaens, Miguel; Sandu, Corina; He, Rui; McBride, Sterling; Alatorre Vazquez, Angel Gabriel; Victorino, Alessandro Correa (Institute of Electrical Engineers of Japan, 2019)
    The development of high-performance mechatronic systems as well as the strong demand for environment-acceptable and safe intelligent technologies have had a profound impact on vehicle engineering. This impact has resulted ...
  • Difference thresholds for a vehicle on a 4-poster test rig 
    Grabe, Roland Peter; Kat, Cor-Jacques; Van Staden, Paul Jacobus; Els, Pieter Schalk (Elsevier, 2020-09)
    Improving vibration-induced discomfort often requires a reduction in the vibration experienced by vehicle occupants. Simulation software and test equipment are able to measure changes in vibration that are too small for ...
  • Difference thresholds for primary and secondary ride of a vehicle on a 4-poster test rig 
    Kat, Cor-Jacques; Grabe, Roland Peter; Van Staden, Paul Jacobus; Botha, Tanita; Els, P.S. (Pieter Schalk) (Taylor and Francis, 2024)
    Not only is it important to know how large the overall change in vibration should be for occupants to perceive an improvement in comfort, but also how large this change should be in specific frequency bands. Relative ...
  • Methodology for developing a neural network leaf spring model 
    Kat, Cor-Jacques; Johrendt, Jennifer L.; Els, Pieter Schalk (Inderscience, 2017)
    This paper describes the development of a neural network that is able to emulate the vertical force-displacement behaviour of a leaf spring. Special emphasis is placed on aspects that affect the predictive capability of a ...
  • Ride comfort comparison between suspension modes : input towards designing difference threshold experiments during driving 
    Kat, Cor-Jacques; Praet, Kylian; Dhaens, Miguel; Els, Pieter Schalk (International Society for Terrain-Vehicle Systems, 2022-09)
    Ride comfort is an important topic for on- and off-road suspension design. Difference thresholds of whole-body vibration is important to determine perceptibility of changes in a vehicle’s dynamics. Difference thresholds ...
  • Single- versus double-row repair for full-thickness rotator cuff tears using suture anchors. A systematic review and meta-analysis of basic biomechanical studies 
    Hohmann, Erik; König, Anya; Kat, Cor-Jacques; Glatt, Vaida; Tetsworth, Kevin; Keough, Natalie (Springer, 2018)
    PURPOSE : The purpose of this study was to perform a systematic review and meta-analysis comparing single- and double-row biomechanical studies to evaluate load to failure, mode of failure and gap formation. MATERIALS AND ...
  • Validation metric based on relative error 
    Kat, Cor-Jacques; Els, Pieter Schalk (Routledge, 2012)
    Engineers and scientists are often faced with the problem of objectively comparing time histories of measured and/or simulated data. This article presents a reliable and intuitive validation metric for use in the validation ...
