Geers, A.M. (author)The goal of this study was to assess if the superposition principle is valid in head-neck stabilization during combined torso perturbations and continuous galvanic vestibular stimulation. Nine seated subjects were perturbed in lateral direction on a motion platform while GVS was simultaneously applied. Both the mechanical and galvanic input...master thesis 2012

Kielstra, J.L. (author)Needle wells are conventional well-bores that contain several hundreds of laterals, called needle holes. The reservoir contact area is increased by these holes, which enables enhanced hydrocarbon production. The needle holes are created by dedicated pipes that are equipped with nozzles. These pipes are mounted in a special liner that is lowered...master thesis 2012

(author)Using three different precursors [MeCpPtMe3, Pt(PF3)4, and W(CO)6], an ultra-high vacuum surface science approach has been used to identify and rationalize the effects of substrate temperature and electron fluence on the chemical composition and bonding in films created by electron beam induced deposition (EBID). X-ray photoelectron spectroscopy...journal article 2012

Zhao, J. (author)Obstructive Sleep Apnea Syndrome (OSAS) is characterized by periods of cessation and reduction of the nasal airflow during sleep. 2 - 4% of the western population suffers from the OSAS which enormously impacts the sleep quality and is associated with significant morbidity of other diseases. Due to its physical cause, a steady 56% of OSAS...master thesis 2012

Holt, S. (author)The upstream oil and gas industry focuses increasingly on unconventional gas resources to maintain the level of its hydrocarbon reserves. To unlock the full potential of gas shale reservoirs, horizontal wells are drilled and active stimulation of the reservoirs, in the form of multi-stage hydraulic fracturing, is performed. This new technique...master thesis 2011

Rodrigues, F.J.O. (author), Mendes, P. (author), Bartek, M. (author), Mimoun, B.A.Z. (author)In this work a cylindrical electrode array to be used for electrical stimulation of sacral nerve roots is studied in respect to its ability to achieve selective stimulation of various spatial regions of the nerve bundle. Simulation results achieved on a simplified model consisting of 6 electrodes evenly distributed along the sacral root...conference paper 2011

Lawand, N.S. (author), French, P.J. (author), Briare, J.J. (author), Frijns, J.H.M. (author)Cochlear implants work on the principle of direct electrical stimulation of the auditory nerve. It has advantages to replace their traditional wired electrodes by a high-density thin-film multielectrode stimulation array which is relatively small in dimensions, stable, resistant to electrolysis, and offers batch fabrication capabilities with...journal article 2011

Ehtemam, F. (author)Galvanic vestibular stimulation (GVS) alters the firing rates of vestibular afferents and consequently provokes the illusion of movement. In standing balance GVS is used to assess the contribution of the vestibular system, where it has been shown to elicit coherent responses in lower extremity muscles involved in maintaining balance. However, to...master thesis 2011

Strydis, C. (author)HEALTHCARE in the 21st century is changing rapidly. In advanced countries, in particular, healthcare is moving from a public to a more personalized nature. However, the costs of healthcare worldwide are increasing every year. Better use of technology can and should be used to get control of these costs. At the same time, implants have clearly...doctoral thesis 2011

Giraldo, F. (author)The Brain, Body and Behavior department of Philips Research have been working on the development of a new technology based on the stimulation of the human brain through the visual sense. This stimulation is made by a light source that presents specific characteristics (frequencies given by flickering conditions) that can influence the brain...master thesis 2010

Ernens, F. (author)The rapid rates of sea level change in the Caspian Sea since its formation (Proterozoic) have resulted in unique sedimentary sequences, including many oil and gas reservoirs. An important hydrocarbon province is the fine grained-sandstone of the Productive Series in the South Caspian Basin that consist for at least some part of sheetflood...master thesis 2010

Rademakers, C. (author)Assessment of the sodium/potassium (Na/K) pump functioning can play an important role in the early diagnosis of several polyneuropathies. However, currently no method exists that allows in vivo testing of the Na/K pump. Therefore, this study developed a test based on repetitive nerve stimulation at single motor units. In order to evaluate the Na...bachelor thesis 2010

Assink, H.K. (author)This report concerns the development of a jacket for people with balance problems. Patients with failing balance organs can have serious difficulty to maintain their balance. The balance jacket contains a sensor and a belt of actuators. The sensor determines the orientation of the patient and provised feedback to the jacket. The jacket contains...master thesis 2010

Van Dongen, M.N. (author)Neural stimulators have the potential of becoming very important devices for the treatment of a wide variety of diseases. One of the major problems with existing stimulators is the limited waveform adjustability. This precludes the use of sophisticated stimulation programs and thereby affects the efficacy of the therapy applied. Another issue is...master thesis 2009

Beers, P.J. (author), Boshuizen, H.P.A. (author), Kirschner, P.A. (author), Gijselaers, W. (author), Westendorp, J. (author)Many researchers use information and communications technology (ICT)-tools to augment learning in a great variety of tasks. Their effects are generally measured in terms of intended outcomes. This article argues for the use of additional, more general measures to obtain a more complete impression of the effects of ICT-tools. The first study...journal article 2008
