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...

This thesis presents a comparison between two different beamforming algorithms, the delay-and-sum beamformer (DSB) and the minimum variance distortionless response (MVDR) beamformer using both objective and subjective metrics. Simulations and measurements have been performed on near-field scenarios with an ad-hoc microphone array. Microphones...

The endoscopic time-of-flight (TOF) positron emission tomography (PET) concept has many advantages compared with the traditional PET system. It improves the image quality by delivering higher spatial resolution and enhancing the signal-to-noise ratio. Implementing the endoscopic TOF PET system in an ultrasonic probe requires an ultra...

With the use of multi-core architectures, the Network-on-Chip (NoC) became an important research topic. The most important benefit of a NoC compared to a communication bus is that it is scalable. The heart of the NoC is the router, which provides the communication between different computational units. This component is highly suitable to be a...

Because of several - sometimes extreme - complications caused by cracks and weak spots in a metal industry roll, it is of great importance to detect these defects in time. Measurements on rolls with artificial- and natural defects have been performed. An imaging operator is introduced, which uses the measurement data to depict the correct...

The intertwine of the optical and acoustic domains by the photoacoustic effect has given rise to the novel technique of photoacoustic imaging. As a relatively new field it faces many challenges from different character on the way to clinical applications. One of these challenges, which deteriorates image quality and sharpness, is noise. The...

The ability to reliantly identify people is an ever growing desire. 3D imaging devices provide major new possibilities in this field. This thesis presents a method which uses a Microsoft Kinect to acquire a depth map of a persons face and transforming this into a point cloud that can be used for further processing into a 3D model of a subjects...

A 3D face recognition algorithm has been developed for the Microsoft Kinect in the scope of the final bachelor project at the TU Delft in 2013. The aim of the project is to develop a prototype face recognition system. The prototype system had to outperform the existing 2D face recognition system. The project is divided into three subgroups each...

Accurate time synchronization is crucial for many applications of Wireless Sensor Networks. Extensive research is performed on this topic, however, there are some aspects of time synchronization which still require attention. In this thesis we investigate aspects of the network which influence the accuracy of packed based time synchronization in...
