D'Amelio, V. (author), Chmarra, M.K. (author), Tomiyama, T. (author)Qualitative reasoning can generate ambiguous behaviors due to the lack of quantitative information. Despite many different research results focusing on ambiguities reduction, fundamentally it is impossible to totally remove ambiguities with only qualitative methods and to guarantee the consistency of results. This prevents the wide use of...journal article 2013

Rudinac, M. (author)Before a future with household robots is really feasible, those robots need to be easily adaptable to novel environments and users, be able to apply previously acquired knowledge, and able to learn from perceiving and interacting with the world and users around them. This thesis proposes a cognitive architecture and a set of underlining methods...doctoral thesis 2013

Saffarian, M (author), de Winter, J.C.F. (author), Happee, R. (author)A car-following assisting system named the rear window notification display (RWND) was developed, with the aim of improving a driver's manual car-following performance. The RWND presented lead-car acceleration and time headway (THW) (i.e., intervehicle distance divided by the speed of the following car) on the rear window of a lead car, which...journal article 2013

Lassooij, J. (author), Tolou, N. (author), Tortora, G. (author), Caccavaro, S. (author), Menciassi, A. (author), Herder, J.L. (author)This article presents the design of a newly developed 2DoF robotic arm with a novel statically balanced and bi-stable compliant grasper as the end effector for laparoscopic surgery application. The arm is based on internal motors actuating 2 rotational DoFs: pitch and roll. The positive stiffness of the monolithic grasper has been compensated...journal article 2012

Akman, O. (author)The field of Computer Vision is concerned with problems that involve interfacing computers with their surrounding environment through cameras. Consequently artificial vision systems can replace human perception in many tasks. Recent advances in technology, such as increase in computational power, good quality low cost CMOS cameras, improvement...doctoral thesis 2012

Gustus, A. (author), Stillfried, G. (author), Visser, J. (author), Jörntell, H. (author), Van der Smagt, P. (author)An overview of mathematical modelling of the human hand is given. We consider hand models from a specific background: rather than studying hands for surgical or similar goals, we target at providing a set of tools with which human grasping and manipulation capabilities can be studied, and hand functionality can be described. We do this by...journal article 2012

Schuitema, E. (author)Service robots have the potential to be of great value in households, health care and other labor intensive environments. However, these environments are typically unique, not very structured and frequently changing, which makes it difficult to make service robots robust and versatile through manual programming. Having robots learn to solve...doctoral thesis 2012

Van der Eijk, A.C. (author)The focus of this thesis is on supplemental oxygen therapy and intrave nous (IV) therapy in neonatal intensive care. Both therapies are essential, but potentially dangerous for (preterm) newborn infants. Supplemental oxygen therapy refers to the therapy where a gas mixture with >21% of oxy gen is supplied to the patient via (mechanical)...doctoral thesis 2012

Rodrigues, S.P. (author), Ter Kuile, M. (author), Dankelman, J. (author), Jansen, F.W. (author)This study was conducted to adapt and validate a patient safety (PS) framework for minimally invasive surgery (MIS) as a first step in understanding the clinical relevance of various PS risk factors in MIS. Eight patient safety risk factor domains were identified using frameworks from a systems approach to patient safety. A questionnaire was...journal article 2012

Van der Krogt, H.J.M. (author), Meskers, C.G.M. (author), De Groot, J.H. (author), Klomp, A. (author), Arendzen, J.H. (author)Background: Movement disorders after stroke are still captured by clinical gaze and translated to ordinal scores of low resolution. There is a clear need for objective quantification, with outcome measures related to pathophysiological background. Neural and non-neural contributors to joint behavior should be separated using different...journal article 2012

Alta, T.D.W. (author), Veeger, H.E.J. (author), Janssen, T.W.J. (author), Willems, W.J. (author)Background It has been suggested that limited active ROM of reverse shoulder prostheses relates to lack of strength. However, the postoperative strength has not been quantified. Questions/purposes We therefore measured joint torques in patients with reverse shoulder prostheses and correlated torques with functional scores. Methods We recruited...journal article 2012

Okken, L.M. (author), Chmarra, M.K. (author), Hiemstra, E. (author), Jansen, F.W. (author), Dankelman, J. (author)Various steerable instruments with flexible distal tip have been developed for laparoscopic surgery. The problem of steering such instruments, however, remains a challenge, because no study investigated which control method is the most suitable. This study was designed to examine whether thumb (joystick) or wrist control method is designated for...journal article 2012

Loeve, A.J. (author)Flexible endoscopes (long, slender, flexible instruments with a camera and light at the distal end, having working channels to introduce flexible instruments) are used for diagnostic and therapeutic interventions inside the human digestive system and inside the abdomen. Though used for their flexibility, the flexibility of these instruments...doctoral thesis 2012

Katzourakis, D. (author)The goal of this thesis is to propose steering support systems that can reduce the driver’s control effort, mental load and promote safety. The driver dictates the vehicle’s motion and the support should centralize him/her in the control loop; thus our design philosophy is to increase driver’s responsibility and support him/her in the sense of...doctoral thesis 2012

Smit, G. (author), Bongers, R.M. (author), Van der Sluis, C.K. (author), Plettenburg, D.H. (author)Quantitative data on the mechanical performance of upper-limb prostheses are very important in prostheses development and selection. The primary goal of this study was to objectively evaluate the mechanical performance of adult-size voluntary opening (VO) prosthetic terminal devices and select the best tested device. A second goal was to see...journal article 2012

(author)Background Resuscitation at birth with 100% oxygen is known to increase the oxidative burden with concomitant deleterious effects. Although fractions of inspired oxygen (FiO2)?<?100% are widely used in preterm infants, starting resuscitation at a (too) low FiO2 may result in hypoxia. The objective of this study is to compare the safety and...journal article 2012

Huan, Z. (author), Fratila-Apachitei, L.E. (author), Apachitei, I. (author), Duszczyk, J. (author)In this study, a porous oxide layer was formed on the surface of 316L stainless steel (SS) by combining Ti magnetron sputtering and plasma electrolytic oxidation (PEO) with the aim to produce a polymer-free drug carrier for drug eluting stent (DES) applications. The oxidation was performed galvanostatically in Na3PO4 electrolyte. The surface...journal article 2012

Wolterbeek, N. (author), Garling, E.H. (author), Mertens, B.J. (author), Nelissen, R.G.H.H. (author), Valstar, E.R. (author)Background The mobile-bearing variant of a single-radius design is assumed to provide more freedom of motion compared to the fixed-bearing variant because the insert does not restrict the natural movements of the femoral component. This would reduce the contact stresses and wear which in turn may have a positive effect on the fixation of the...journal article 2012
