System Identification using Dynamic Expectation Maximization: From neuroscientific principle towards filtering and identification under the presence of correlated noise

A fundamental task of intelligent and autonomous robots is to infer from observations the state of the world. This inference is generally achieved by employing a filter, which consists of a model and filtering law. Learning this model and filtering law from observations is another fundamental part of robotics, and is generally referred to as...

Filtering Quasiperiodic Noise from Biomedical Images

In the field of biomedical imaging, images often report a combination of biologically induced variation, usually the goal of the imaging process (e.g. outlining an anatomical region or disease pattern), and non-biological variation, such as instrument or acquisition method-induced noise patterns. <br/>Since some medical decisions are made based...

Linear and anisotropic diffusion in image processing: A study on implementation, parameters and segmentation

The TU Delft and the LUMC are creating a low-field MRI scanner to use in third world countries. This type of MRI scanner has many advantages, but a downside is the amount of noise in the obtained images. A way to reduce noise is diffusion filtering. This thesis discusses the theory of some linear and nonlinear diffusion filtering methods and...

Observing Solid Concentrations in a Vertical Hydraulic Transport System

At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).<br/><br/>In the VTS insight of the...

Autonomous Nevigation of Nano-satellites during Earth-Moon Transfer

Improved Lens Aberration Estimation Using Model-Based Filtering, Applied to Lithographic DUV Imaging Systems

In this thesis a model-based filter is developed to improve the estimates of the lens aberrations.

Black-Box assessment of Web systems security

Many companies rely on Web applications to promote their services to the world. It is a logical step, as the Web offers great advantages such as convenience, low cost and instant reachability from anywhere in the world. Meanwhile Web applications tend to be implemented in an insecure way and the attacker does not even need to be too experienced...

Fixed-Wing UAV Integrated Navigation with Low-Cost IMU/GPS

Today, there is an increase in the use of Unmanned Aerial Vehicles (UAV's), for applications that can be considered dull, dirty or dangerous when compared to those applications of conventional aircraft or helicopters. To further increase the use of UAV's, their navigation filters must be robust and reliable. The trend in current autopilot...
