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...

Localization has an import role in wireless sensor networks, as it adds context to gathered data. The goal of this thesis is to create an application that determines the location of a mobile sensor node in an indoor environment. A secondary goal is to get practical experience with indoor localization. Previously, in a literature review, we...

This thesis is a part of the CLEMPS (Closed Loop Embedded MEMS-based Precision Stage) project. Within this project a MEMS-stage should be positioned using a feedback (displacement) signal with 10-nm accuracy over a 100 ?m range. This thesis investigates if thermal sensing can be used as a reliable sensing mechanism within the CLEMPS project....

A wireless sensor network (WSN) consists of multiple small and simple computers (nodes), whose performance is tightly linked to its unpredictable deployment environment. It is nearly impossible to design a WSN that performs well in every scenario; instead they are developed for a specific context, with performance rapidly decreasing when...

As the world is in need of more sustainable energy sources, the use of new gases like hydrogen or bio-gases seems to be a very attractive one. By mixing these new gases with the traditional natural gas, it becomes possible to have a smooth and economically durable transition. The amount of new gases added may be dependent on the availability,...

Los Bronces is an open pit mine located on a large porphyry copper-molybdenum deposit near Santiago, Chile. Annual production is around 240 000 tonnes of copper and 2 700 tonnes of molybdenum. The extracted ore has a relatively low average copper grade of around 0.6%. This results in relatively high processing costs and creates the need to...

Obesity is a growing problem among children. They seem to eat less healthy and live a sedentary lifestyle. Children who are overweight have troubles during sport, can get depressed and suffer more consequences. But are they really to blame? The parents of these children have the responsibly of keeping their children healthy. However some parents...
