In this thesis the different aspects of acquiring the complex refractive index of interstellar ice analogues are treated. The ultimate aim of this work is to search for abilities to predict the infrared absorption spectra of these analogues. A key factor in these predictions is the optical influence …

The company, Tekt Industries, is developing two LED driver boards which can be connected to the network or by a USB connection. Each device connected to a local network has a unique IP address and a port number to where data can be sent. The user must remember the IP address and port number of a driver …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

Remote maintenance activities in ITER will be performed by a unique set of hardware systems, supported by an extensive software kit. A layer of middleware will manage and control a complex set of interconnections between teams of operators, hardware devices in various operating theatres, and databases …

Experimental setup of motivating physiotherapy clients to perform balancing exercises at home through the use of a game with custom ‘wobble board’ hardware and iPadaccelerometer data.

The characteristics of a hydrogen plasma in an inductively coupled RF plasma setup were studied using a double Langmuir probe and an optical emission spectrometer. At various settings for the gas pressure, gas ow, RF power and probe position, values were obtained for the electron temperature and plasma …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

This report is written to guide the reader step by step through the process of developing a heating stage and a iron mapping device for a photoluminescence setup, used to measure the lifetime of silicon wafers in solar cells. Subject specific terms will be explained throughout the report. First, research …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

Resonance-enhanced laser-induced breakdown spectroscopy was used to increase the elemental sensitivity of laser-induced breakdown spectroscopy. In resonance-enhanced laser-induced breakdown spectroscopy, two lasers are used. The first laser creates a plasma, and the second laser re excites the most …
