Model based image reconstruction for low-field hand-held MRI: On imaging using field geometry and sample translations

In this report, the conversion from spin-echo signals, obtained with a low-field hand-held MRI scanner that was designed and built at the Leiden University, to images of the proton density within the sample is considered. This scanner does not make use of switchable gradient coils, but instead relies solely on the natural inhomogeneity of the...

Evaluating Temperature Impact on Solar Home Systems (SHS): From the components to the systems level

Access to electricity still lacks for a fifth of the world's population. Most of the areas are in the remote rural location. Due to the off-grid location, policies, and other social factors, the grid expansion in these areas is not economically viable. Installing Solar Home Systems (SHS) is considered to be a promising immediate solution, given...

Distinctions in heat pump pools for participation in the Dutch balancing market

Electricity is a basic need in today`s society, being present in almost every aspect of life. The extensive infrastructure that transports electricity to the consumers, is expected to always work. At the same time there is a growing realism that the energy sector needs to modernise and ‘greenify’, in order to become more climate friendly. This...

Designing an Innovative Brake Control System

Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...

Establishing a sea bottom model by applying a multi-sensor acoustic remote sensing approach

Detailed information about the oceanic environment is essential for many applications in the field of marine geology, marine biology, coastal engineering, and marine operations. Especially, knowledge of the properties of the sediment body is often required. Acoustic remote sensing techniques have become highly attractive for classifying the sea...
