Mokkink, L.B. (author), de Vet, H. (author), Diemeer, S. (author), Eekhout, I. (author)Simulation studies were performed to investigate for which conditions of sample size of patients (n) and number of repeated measurements (k) (e.g., raters) the optimal (i.e., balance between precise and efficient) estimations of intraclass correlation coefficients (ICCs) and standard error of measurements (SEMs) can be achieved. Subsequently, we...article 2022

Burford, E.M. (author), Botter, J. (author), Commissaris, D. (author), Könemann, R. (author), Hiemstra-Van Mastrigt, S. (author), Ellegast, R.P. (author)The effect of different workstations, conventional and dynamic, on different types of performance measures for several different office and computer based task was investigated in this research paper. The two dynamic workstations assessed were the Lifespan Treadmill Desk and the RightAngle LifeBalance Station, and the two conventional...conference paper 2013

Evers, W.-J. (author), Besselink, I.J.M. (author), Teerhuis, A.P. (author), Oomen, T. (author), Nijmeijer, H. (author), TNO Industrie en Techniek (author)There is a large body of literature on model validation, but there is no method available that can effectively use asynchronous repeated measurements with low signal-to-noise ratios. The aim of this paper is to present a novel frequency-domain model validation method, which is suitable for this type of measurements. The practical relevance of...conference paper 2010

de Korte, E.M. (author), de Kraker, H. (author), Bongers, P.M. (author), van Lingen, P. (author), TNO Kwaliteit van Leven (author)To study the effects of a tactile feedback signal in a computer mouse on reduction of hovering behaviour and consequently on changes in muscle load, productivity, comfort and user friendliness, a comparative, experimental study with repeated measures was conducted. Fifteen subjects performed five trials with different mouse actions and a...article 2008

(author), TNO Kwaliteit van Leven (author)Objectives: Workers in many industries are exposed to endotoxins, which may cause adverse health effects. In exposure assessment, information about exposure variability is essential. However, variability in exposure has rarely been investigated for biological agents and more specifically for endotoxin. Therefore, variance components and...article 2008
