Design and Validation of Ungrounded Wrist Perturbator Based On Parallel Mechanism

The compliance (stiffness) of a human arm varies, depending on the task at hand. Some precise tasks require high stiffness, while others need a level of flexibility to deal with unknown disturbances. To describe this human behaviour a portable device is needed to give small force perturbations (input) while the resulting reaction of the arm ...

Implementation and Evaluation of Packed-SIMD Instructions for a RISC-V Processor

With the increase in the amount of data being gathered, the need for data processing is also rising. Furthermore, in addition to the proprietary ISAs that have been prevalent, the free and open RISC-V ISA has seen major interest. The modularity of the RISC-V ISA allows it to be extended with many instruction set extensions. One such extension...

SoftGlove: Finger Vibrotactile Feedback

In this report the finger vibrotactile subsystem of the SoftGlove wearable haptic feedback glove is discussed. This system is an upgrade over the vibrotactile feedback that the current SenseGlove haptic feedback glove provides. The designed system consists of a linear resonant actuator (LRA) on each finger, which is controlled by a dedicated LRA...

Evaluation of Micromixing Models for Turbulent Mixing in Supercritical Water

Hydrothermal flames have become a very important field of study, especially for supercritical water oxidation. In supercritical water oxidation hazardous, toxic or non-biodegradable aqueous organic waste water streams can be efficiently destructed. Supercritical water oxidation takes place in a aqueous environment above the supercritical point....

Urban Stress: Research into the reduction of urban stress through urban design

Stress is a well-known phenomenon and something everyone experiences. Urban stress however, stress caused by and in the built environment of urban areas, is less known. Still, quite some research has been done on this topic from the fields of sociology and psychology, but there are not many resources that focus on urban stress - with all its...

Data-driven 3D Deghosting Using Multisensor Marine Measurements

Marine seismic acquisition tows submerged streamers to record pressure waves from the subsurface. The recording, however, contains both the desired upgoing wavefield and its (immediate) reflection off the sea-surface, causing a downgoing wavefield known as the seismic ghost. Interference between the up- and downgoing waves causes periodic low...

Transmissie-aspecten van het scribofoonsysteem bij gemengd analoog/ digitale verbindingen

De toenemende digitalisering van telefoonnetten (zowel openbare als bedrijfsnetten) maakte het noodzakelijk het scribofoon transmissiesysteem op dit aspect nader te onderzoeken. In het bijzonder werd hiertoe onderzoek verricht aan digitalisering met puls code modulatie (PCM), van een frequentie-multiplex signaal voor de combinatie van spraak en...
