Ultra low latency deep neural network inference for gravitational waves interferometer: *

Low latency Convolutional Neural Network (CNN) inference research is gaining more and more momentum for tasks such as speech and image classications. This is because CNNs have the ability to surpass human accuracy in classication of images. For improving the measurement setup of gravitational waves, low latency CNNs inference are researched. The...

Towards Automated and Fast Whisker Tracking in Rodents

Whisker tracking in rodents is an ongoing research in neuroscience. Neuroscientists have recorded experiments with high-speed cameras in which untrimmed, head-restrained mice are provided with air stimuli. These videos required the development of algorithms to reliably track whisker movement. Recently, a Whisker Tracking System, WhiskEras,...

Acceleration Magnification for Visualising Blood Flow Pulsation in the Skin

While millions of people world wide suffer from arterial diseases, such as peripheral arterial disease, there are a limited number of methods that can be used to diagnose and track these diseases which are also easy, quick and non-invasive. <br/><br/>This work focuses on what is needed to improve diagnosing and tracking of peripheral arterial...

High Throughput Sorting on FPGAs using High Bandwidth Memory

In this thesis we explore the acceleration of sorting algorithms on FPGAs using high bandwidth memory (HBM). The target application is an FPGA as an accelerator in an OpenCAPI enabled system, that enables the accelerator to access main memory of the host at a bandwidth of 25 GB/s for either read or write. We explore under what read and write...

Collaborate to accelerate: Exploring the empirical perspective on accelerating the initiation phase of inner-city redevelopment projects: from Industrial to mixed work-residential areas

The Dutch housing market is currently dealing with a significant dwelling deficit, which results in the need to accelerate the development of large quantities of dwellings in the urban areas. This thesis studies the redevelopment of inner-city industrial sites into mixed work-residential areas, especially focussing on the collaboration process...

Rocking Revisited 1: Rocking of a Singe Cube on a Breakwater Slope

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

Assessment of passenger comfort according to Eurocode in Dutch trains travelling over tied-arch railway bridges

With increasing velocities of trains, passenger comfort starts to play a larger role in the design of railway bridges. There is little experience with the Eurocode passenger comfort criterion in the Netherlands. It is relevant for the industry to have a way to fulfil this criterion, also in an early stage of railway bridge design. A sufficiently...

Human-induced vibrations on footbridges: A probability-based approach of the vibration serviceability of footbridges under vertical pedestrian loading

In structural design there is a tendency towards more slender and challenging architectural structures. Footbridges become more slender with an increasing high ratio live load to dead weight. A consequence of this increased slenderness of footbridges in an increased susceptibility to human-induced vibrations. The evaluation of the serviceability...

Trillingen van betonnen voetgangersbruggen / Vibrations of concrete footbridges

Nowadays more and more slender concrete footbridges are designed. Footbridges are designed thinner to increase esthetic value, as well as incorporate sustainability and to reduce building costs, with a consequence that the eigenfrequency of the bridge can drop so low that it may fall into a range of frequencies that is susceptible to vibrations...

Incorporation of the effects of accelerating flow in the design of granular bed protections

For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...

Control of Voicecoil transducers: Design and implementation of a Motional Feedback Loudspeaker Woofer

This master thesis describes the dynamical behaviour of a loudspeaker woofer and the modelling of it. By the use of the knowledge gained from the model, a feedback controller is implemented in order to enhance the woofer’s performance in terms of acoustic total harmonic distortion (THD) and low frequency bandwidth. The first objective of the...

Continuous Impedance, Force, and Acceleration Monitoring for Motion Artefact Reduction in EEG

Electroencephalograph (EEG) is used in various applications such as diagnosing patients suffering from epilepsy or seizures. Motion artefact is the noise recorded together with the desired biopotential signals. It is mainly introduced by the relative motion between the measurement electrode and the human scalp. Dry electrodes are preferred in...

Traffic Accelerator

Model that generates an optimized urban infratructure and morphology to accomodate accelerating traffic

Using a drinking water treatment simulator for operator training: Accelerating the simulated process leads to an increase in learning

The drinking water treatment industry is becoming increasingly centralized and automated. This requires a different operator training approach then the traditional on the job training. To address this requirement a drinking water treatment plant simulator was developed. A major advantage of such a simulator might be that the normally very slow...
