Wavefront Reconstruction from Intensity Based Images for High Resolution Microscopy

In the DCSC group of Prof. Michel Verhaegen a new type of fluorescence microscope has been developed that relies on adaptive optics to correct for aberrations using optimisation of an image metric. The aim of this thesis is to realise a complete simulation of the optical system, and to test a variety of optimisation algorithms in simulation,...

Design of a Real-Time Micro-Winch Controller for Kite-Power Applications

Design of a real time steering and depowering controller for kite power applications. The controller includes kite tapes tension estimation, tension limitation, and current limitation.

Persistent self-supervised learning principle: Study and demonstration on flying robots

We introduce, study and demonstrate Persistent Self-Supervised Learning (PSSL), a machine learning method for usage onboard robotic platforms. The PSSL model leverages a standard supervised learning method to simplify the learning problem, but acquires training data in an unsupervised and autonomous manner. Using two platforms, a small...

Sensor-Assisted Movement Identification and Prediction for Beamformed 60 GHz Links

The 60 GHz frequency band promises very high data rates { in the order of Gb/s { due to the availability of large amounts of bandwidth. High free- space path loss at the 60 GHz frequency band makes it necessary to employ beamforming capable directional antennas to confine signal power in the desired direction. When beamforming is used, the links...

Vision-based velocity control on a Philips Experimental Robot Arm

The challenge in this thesis is to find out if an off-the-shelf embedded system can replace an off-the-shelf laptop or desktop computer when its task is to perform vision-based velocity control using inverse kinematics on a robotic arm. The results of this thesis are that an algorithm was developed which had to be tested in simulation and should...

Scalable Real-Time Hardware for 2D Empirical Mode Decomposition

This thesis describes the feasibility of implementing Empirical Mode Decomposition on an FPGA.

Soft Sensors Development for Model Based Control of Groundwater Treatment Plants

The drinking water in the Netherlands has been aimed to achieve high quality of water along with a low production cost. In-order to produce such high quality of treated water, constant monitoring of the process variables at the end of each treatment step is recommended. These processes are monitored and operated by motivated and skilled...

A Spatial Computing Approach to Programming Large Scale Wireless Sensor Networks

The technology required to design and deploy large scale wireless sensor networks is available, affordable and shows an increased interest in various application domains. However, application development for distributed systems is a cumbersome task, typically carried out with low-level embedded programming paradigms. A middleware is usually...

Real-Time Object Identification using SURF Key-Points

The thesis here addresses the topic of image features and how they can be used in object identification. Two state of the art algorithms Scale Invariant Feature Transform (SIFT) and Speeded-Up Robust Features (SURF) are studied and their qualities are measured and based on the results of these tests the best algorithm, SURF, is chosen for...

An OpenCL-based Solution for Portable Bodyscan SAR Processing on Multicore Platforms

Multicore systems have become an indispensable part of our everyday life. They represent a viable alternative for increasing processor performance without hitting the memory and power walls. However, the shift from traditional programming to multicore programming has a critical influence in three dimensions: the applications, the software tools,...

Radio Wave Propagation in Metal Train Compartments

Wireless sensor networks are being deployed extensively to collect sensory data in various environments under different conditions. A wireless sensor network consists of multiple nodes, each with the ability to communicate using radio waves. The characteristics of the radio link between nodes are largely influenced by their environment. For...
