Naar landelijke learning communities: Leerervaringen uit twee jaar learing community logistiek in de leefbare stad

Learning communities kunnen een middel zijn om bij vraagstukken zoals logistiek in de leefbare stad, in een publiek-privaat samenwerkingsverband te leren, problemen op te lossen en te innoveren. Vanuit het CoE KennisDC Logistiek is door vier hogescholen de Learning Community Logistiek in de Leefbare Stad uitgevoerd. Op basis van het Conceptueel...

Doplor Sleep: Monitoring Hospital Soundscapes for Better Sleep Hygiene

Good sleep is conducive to the recovery process of hospital patients - and yet, in many wards, sleep duration and quality can often be suboptimal, in part due to modifiable hospital-related sounds and noises. At the neurological ward of the Reinier de Graaf hospital in Delft, the Netherlands, we developed and evaluated a prototype information...

Exploring profiling and personalisation in sleep music design: Towards conceptualising musical sleep aids for hospital use

Music as a low-cost sleep aid is a promising way to improve the sleep quality of people. However, most available sleep music playlists are limited to generic, soothing songs, which do not take in account personalisation. In collaboration with the Neurology Department of the Reinier de Graaf hospital (Delft, The Netherlands), we explored a...

Vibration-assisted decommissioning of a slip joint: Application to an offshore wind turbine

An alternative option to the traditional grouted joint for wind turbines is a direct steel-to-steel connection, also known as slip joint. In a recently published work, a proof of concept of a vibration-assisted installation and decommissioning technique of a slip joint was illustrated. Leveraging on the obtained results, the current study shows...

Positron range-free and multi-isotope tomography of positron emitters

Despite improvements in small animal PET instruments, many tracers cannot be imaged at sufficiently high resolutions due to positron range, while multi-tracer PET is hampered by the fact that all annihilation photons have equal energies. Here we realize multi-isotope and sub-mm resolution PET of isotopes with several mm positron range by...

EXIRAD-3D: Fast automated three-dimensional autoradiography

Introduction: Autoradiography is an established technique for high-resolution imaging of radiolabelled molecules in biological tissue slices. Unfortunately, creating a 3D image from a set of these 2D images is extremely time-consuming and error-prone. MicroSPECT systems provide such 3D images but have a low resolution. Here we present EXIRAD...

Accelerated image reconstruction by a combined dual-matrix dual-voxel approach

Today, versatile emission computed tomography (VECTor) technology using dedicated high-energy collimation enables simultaneous positron emission tomography (PET) and single photon emission computed tomography (SPECT) down to 0.6 mm and 0.4 mm resolution in mice, respectively. We recently showed that for optimal resolution and quantitative...

Evaluation of pinhole collimator materials for micron-resolution ex vivo SPECT

Pinhole collimation is widely recognized for offering superior resolution-sensitivity trade-off in SPECT imaging of small subjects. The newly developed EXIRAD-3D autoradiography technique (MILabs B.V.) based on a highly focusing multi-pinhole collimator achieves micron-resolution SPECT for cryo-cooled tissue samples. For such high resolutions...

Spectral EMG changes in Cervical Dystonia patients and the influence of botulinum toxin treatment

Botulinum toxin (BoNT) injections in the dystonic muscles is the preferred treatment for Cervical Dystonia (CD), but the proper identification of the dystonic muscles remains a challenge. Previous studies showed decreased 8–14 Hz autospectral power in the electromyography (EMG) of splenius muscles in CD patients. Cumulative distribution...

The environment provides the reference frame for self-motion perception

Computation of Coastal Morphology

To solve coastal sediment transport and morphology problems, it is necessary to construct a hydrodynamics model to simulate the fluid flow. The hydrodynamics model is then used to calculate sediment transport rates and in turn, these sediment transport rates are used to determine morphology. The hydrodynamics model is based on the Equation of...

Overzicht diverse ecologische gericht metingen op de Noordzee in 1991.

Kasteel Nederhemert: Een oriëntatie op de bouwgeschiedenis

De Werkgroep Restauratie, opgericht in 1967 om aan de afdeling der Bouwkunde van de Technische Hogeschool Delft de specialisatie tot restauratie-architect mogelijk te maken, werd in 1977 door de afdelingsraad als werkgroep volgens de Wet Universitaire Bestuurshervorming goedgekeurd. Binnen de studiespecialisatie Restauratie is de laatste jaren...

Scale Selection for Wave Models

The selection of scales for models with short waves, long waves and unindirectional current is discussed with particular emphasis on boundary layer motion and movement of sediment. The paper attempts to outline the present state of the art and to provide a framework for future research in the area of coastal sediment transport models at Queen's...

Eldo-Pas: Attitude determination program for a spinning satellite using only one wide field horizon sensor

ELDO-PAS Attitude determination during the transfer orbit with associated launch windows aspecs

The problem of attitude determination of the PAS vehicle during the transfer orbit is analyzed. Of the four ways of using the primary angles measured by the sensors, one is discussed in detail. The problem of transforming the primary angles into a suitable set of presentation angles is discussed. The use of a few sets of possible presentation...
