Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …

Doel van dit onderzoek is 1a. Is het mogelijk om een Critical Velocity (CV) te bepalen voor getalenteerde schaatsers? 1b. Rijden de proefpersonen op CV met een steady state in hun zuurstofopname? 2. Is er een relatie tussen slagfrequentie/e hoek en het kunnen volhouden van CV? Methode: De CV is bepaald …

The effect of alterations in the processing of proprioceptive signals, on postural control, has been studied using muscle vibration effects. However, reliability and agreement of muscle vibration have still to be addressed.This study aimed to assess intra- and interday reliability and agreement of vibration …

Cardiovascular disease is an important cause of disability in activities of daily living (ADL) through its effect on physical functioning. However, it is unclear whether subclinical vascular abnormalities and rate of change in subclinical vascular abnormalities is also associated with an impaired physical …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

Knowing firefighters’ locations in a burning building would dramatically improve their safety. In this study from the Saxion Research Centre for Design and Technology in the Firebee project, an algorithm was developed and tested to enhance the estimation of a person’s location, based on inertial measurements …

Background Information: Slumped sitting has been associated with low back pain. Low back pain has shown to affect postural stability. In the lower back of a healthy person, little is known about the effects slump sitting has on motor control and sway. Objective: To investigate if there are differences …

Optical Coherence Tomography (OCT) is an imaging technique for collecting depth resolved information in human tissue based on an interferometer. With an imaging depth of between 1 and 2 mm, OCT is only used to investigate (near) surfaces. But with an axial (depth) resolution of between 2 and 10 μm, and …

Satellites are an increasingly important tool in modern warfare and, as such, there is a renewed interest in developing anti-satellite weapons, as well as in assessing the vulnerability of satellites to being intercepted. In 2007 China used a modified ballistic missile to intercept a defunct Chinese …

Objectives To evaluate the feasibility and validity of gait parameters measured with an electronic walkway system in predicting short-term fall risk in nursing home residents with dementia. Methods 57 ambulatory nursing home residents with moderate to severe dementia participated in this prospective …
