Introduction In the harbor of Zierikzee there is a strong tidal influence. The difference between the water levels during high and low tide lies around the three meters. The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …

Urban flood prevention is an intensifying prerequisite of urban inhabitation due to a multiplicity of threats to population health and property. One of the components of urbanisation that can fail to fulfil its function and cause urban flooding is gully pot clogging. Frequently this is the result of …

Background A key factor in successfully preventing falls, is early identification of elderly with a high risk of falling. However, currently there is no easy-to-use pre-screening tool available; current tools are either not discriminative, time-consuming and/or costly. This pilot investigates the feasibility …

We present a method for measuring gait velocity of older adults using data from existing ambient sensor networks. Gait velocity is an important predictor of fall risk and functional health. In contrast to other approaches that use specific sensors or sensor configurations, our method imposes no constraints …

Background: A significant part of neurological rehabilitation focuses on facilitating the learning of motor skills. Training can adopt either (more) explicit or (more) implicit forms of motor learning. Gait is one of the most practiced motor skills within rehabilitation in people after stroke because …

Laminated composites have important applications in modern aeronautical structures due to their extraordinary mechanical and environmental behaviour. Nevertheless, aircraft composite structures are highly vulnerable to impact damage, either by low-velocity sources during maintenance or high-velocity …

Mechanical power output is a key performance-determining variable in many cyclic sports. In rowing, instantaneous power output is commonly determined as the dot product of handle force moment and oar angular velocity. The aim of this study was to show that this commonly used proxy is theoretically flawed …

The Amsterdam Sensor Lab is part of the Amsterdam University of Applied Sciences (AUAS) and its goal is to develop application specific sensor systems for applied research. In order to (anonymously) measure, for instance, traffic without influencing people’s behaviour, a pressure sensing sub-tile is …

A few years ago the Dutch government set goals for sustainability. These goals include switching to fully sustainable energy production by 2050. Using only conventional sustainable energy production methods like solar panels and wind turbines will not result in achieving the set goals, so alternative …

Background: Aerobe fitness (AF) is an important component of physical fitness of children and adolescents. To assess the AF, the 20-m Shuttle Run Test (SRT-20) is often used. Unfortunately, there is frequently a lack of an at least 22 m physical facility to utilize this test indoor. By still using the …
