van der Vlist, Rik (author)
A phase estimation algorithm is presented to estimate the phase of a recurring pattern in a nonstationary signal. The signal is modelled by a template signal that represents one revolution of the recurring pattern, and that the frequency of this pattern can change at any time with no assumptions about local stationarity. The algorithm uses a...

Cardiovascular diseases are the leading cause of death in the devel- oped world. Preventing these deaths, require long term monitoring and manual inspection of ECG signals, which is a very time consum- ing process. Consequently, a wearable system that can automatically categorize beats is essential.
Neuromorphic machines have been introduced...

Atrial fibrillation (AF) is one of the more common clinical arrhythmias with a high morbidity and mortality. Despite this, the electrophysiological and pathological mechanisms associated with AF largely remain a mystery, encouraging the use of ever more sophisticated techniques to extract vital information for diagnostic and therapeutic purposes...

The high level of realism of spiking neuron networks and their complexity require a considerable computational resources limiting the size of the realized networks. Consequently, the main challenge in building complex and biologically accurate spiking neuron network is largely set by the high computational and data transfer demands. In this...

Neuromorphic engineering, aiming at emulating neuro-biological architectures in efficient ways, has been widely studied both on com- ponent and VLSI system level. The design space of neuromorphic neuron, the basic unit to conduct signal processing and transmission in nervous system, has been widely explored while that of synapse, the specialized...

This thesis proposes a low-cost high-efficiency source-synchronous interface for high-speed inter-chip communication. The interface is composed of LVDS transceivers as external I/O buffers, and an all-digital data recovery, which can calibrate the received data phase to be aligned to the 90 phase of the received half-rate reference...

The scalable simulation of neuron communication needs a large
amount of computing resources. The high throughput of data cause
the high requirement of interconnect network. This thesis is aimed
at the finding the efficient multi-FPGA connection for the neuron
network. First describe the characteristics of the network in terms

Packet communication applications cannot guarantee correct delivery of every packet. Congestions and interferences in the network lead to lost packets. However, real-time applications require timely delivery of data or information and always tolerate packet loss to achieve this aim. When some speech packets are lost, packet loss concealment (PLC...

Electrical properties tomography is the quantification of the conductivity and permittivity of different materials. In an MRI setting this can be used to map the electrical properties of tissue. These values can be used as a different contrast mechanism, for hyperthermia treatment or the improvement of antenna design for specific applications....

For comprehensive understanding of how neurons communicate with each other, new tools need to be developed that can accurately reproduce and mimic the behaviour of such neurons in real-time. The proposed design in this thesis models an Inferior Olivary Nucleus network on an FPGA device, with a maximised amount of simulated neurons for the given...

In order to verify an application with a simulation, increasing the simulation speed is important. An Inferior Olivary Nucleus (ION) network has been implemented in a SystemC language and its simulation verified by a SystemC testbench. The goal of this thesis is to integrate the ION application into an FPGA in order to increase its simulation...

Traditional imaging techniques in medical ultrasound are mostly based on pre-defined geometrical processing of the measurement data. In this thesis however, we focus on finding the image that would best explain the observed measurement in a least squares sense, given an ultrasound model. This enables the use of prior knowledge such as transducer...

Dielectric shimming is proven to be very useful in increasing the homogeneity of the 𝐵1+ field in high field MRI. Current optimization and design techniques for dielectric pad parameters are slow. The goal of this thesis is to find a fast and accurate pad design and optimization technique. Two new techniques are proposed. The first, a method...

This thesis shows the successful development of an acoustic channel model to be used for optimisation of localisation. It uses an eigenray approximation, implemented as the image source method to determine a channel impulse response. The image source method however limits the model to environments which can be reduced to cuboid shaped rooms as...

The conventional techniques to estimate the Direction-of-Arrival (DOA) of acoustic sources includes employing multiple Acoustic Pressure Sensors (APSs) in an array configuration. Recently with the advent of MEMS technology, the sensors are capable of capturing acoustic particle velocity along with acoustic pressure and these sensors are referred...

This bachelor’s thesis discusses the idea and implementation of real-time heart rate monitoring using photo- plethysmography (PPG) signals. PPG signals measured from the wrist are often subjected to distortion and noise. Signal processing techniques that tackle these issues were investigated and implemented. The algo- rithm of choice was JOSS....

Nowadays, large-scale networks of computing units, often characterized by the absence of central control, have become more commonplace in many applications. To facilitate data processing in these large-scale networks distributed signal processing is required. The iterative behaviour of distributed processing algorithms combined with the limited...

A time-domain (TD) and a frequency-domain (FD) method for time offset (TO) compensation between received audio data are presented and implemented on Android smartphones and a processing computer. Simulations show the TD method is superior in almost all applications. Real-life experiments show the TD synchronization error is below 6 samples. A...
