Dodou, D. (author), Breedveld, P. (author), Wieringa, P.A. (author)One of the main challenges in designing diagnostic devices able to move along the colon is their locomotion method. Generating friction without applying high normal forces is a key requirement in order to eliminate the risk of tissue damage. One possible solution is to generate friction by means of adhesive forces. For this reason, the device...journal article 2006

Dodou, D. (author)The most effective screening method for colonic cancer is colonoscopy. However, colonoscopy cannot be easily embraced by the population because of the related pain intensity. Robotic devices that pull themselves forward through the colon are a possible alternative. The main challenge for such devices is their locomotion method along the slippery...doctoral thesis 2006

Dodou, D. (author), Van den Berg, M. (author), Van Gennip, J. (author), Breedveld, P. (author), Wieringa, P.A. (author)A self-propelling colonoscopic device moving inside the colonic tube should be able to periodically grip safely to the colonic wall as well as to manipulate the generated friction. The feasibility of achieving high grip and friction manipulation by covering the device with mucoadhesive films is experimentally tested. More precisely, the...journal article 2008

De Winter, J.C.F. (author), Dodou, D. (author), De Groot, S. (author), Abbink, D.A. (author), Wieringa, P.A. (author)This paper presents the results of integrating hands-on experience in an engineering MSc course on human-machine systems. Students could voluntarily complete a homework assignment in which they performed manual control tasks using dedicated software. The tasks were accompanied by questions that students had to answer using the theory taught in...conference paper 2010

Breedveld, P. (author), Dodou, D. (author)The invention relates to a propulsion-unit provided with a body and comprising at least one element having an external adhesive layer for providing frictional contact with an object's surface along which the unit in use moves, wherein the element is a supporting layer that supports said adhesive layer, and wherein drive means are provided for...patent 2010

De Winter, J.C.F. (author), Dodou, D. (author)Function allocation is a core activity of the human–machine systems discipline. Sixty years ago, Paul Fitts marked the outset of function allocation research with an 11-statements list. Since then numerous function allocation methods have been proposed, but strikingly the seminal Fitts list spans the entire history of this domain and continues...journal article 2011

De Winter, J.C.F. (author), Dodou, D. (author)Shared control (also known as continuous haptic guidance or haptically active controls) has recently been introduced in car driving. With shared control, the driver receives continuous force feedback on the gas pedal or steering wheel, so that human and machine conduct the driving task simultaneously. Experiments in driving simulators have shown...conference paper 2011

de Winter, J.C.F. (author), Zadpoor, A.A. (author), Dodou, D. (author)Web of Science (WoS) and Google Scholar (GS) are prominent citation services with distinct indexing mechanisms. Comprehensive knowledge about the growth patterns of these two citation services is lacking. We analyzed the development of citation counts in WoS and GS for two classic articles and 56 articles from diverse research fields, making a...journal article 2014

Dodou, D. (author), de Winter, J.C.F. (author)The aim of this meta-analysis was to compare social desirability scores between paper and computer surveys. Subgroup analyses were conducted with Internet connectivity, level of anonymity, individual or group test setting, possibility of skipping items, possibility of backtracking previous items, inclusion of questions of sensitive nature, and...journal article 2014

de Winter, J.C.F. (author), Dodou, D. (author), Hancock, PA (author)The science of Human Factors and Ergonomics (HF/E) often relies on self-report. This is a cause for concern because subjective methods are inherently susceptible to bias. Here, we present, examine and discuss a puzzling association between age and self-reported cognitive failures as assessed with Broadbent's Cognitive Failures Questionnaire (CFQ...journal article 2015

A quarter of a century of the DBQ: some supplementary notes on its validity with regard to accidentsde Winter, J.C.F. (author), Dodou, D. (author), Stanton, NA (author)This article synthesises the latest information on the relationship between the Driver Behaviour Questionnaire (DBQ) and accidents. We show by means of computer simulation that correlations with accidents are necessarily small because accidents are rare events. An updated meta-analysis on the zero-order correlations between the DBQ and self...journal article 2015

De Winter, J.C.F. (author), Dodou, D. (author)It is known that statistically significant (positive) results are more likely to be published than non-significant (negative) results. However, it has been unclear whether any increasing prevalence of positive results is stronger in the "softer" disciplines (social sciences) than in the "harder" disciplines (physical sciences), and whether the...journal article 2015

de Winter, J.C.F. (author), Dodou, D. (author)Common factor analysis (CFA) and principal component analysis (PCA) are widely used multivariate techniques. Using simulations, we compared CFA with PCA loadings for distortions of a perfect cluster configuration. Results showed that nonzero PCA loadings were higher and more stable than nonzero CFA loadings. Compared to CFA loadings, PCA...journal article 2016

Sprang, Tim (author), Breedveld, P. (author), Dodou, D. (author)This paper outlines the development of a four-part needle prototype inspired by the ovipositor of parasitic wasps. In the wasp ovipositor, three longitudinal segments called valves move reciprocally to gain depth in the substrate. It has been suggested that serrations located along the wasp ovipositor induce a friction difference between...conference paper 2016
