Fear of flying in civil airline passengers: a manifold phenomenon with various motivational roots

This thesis comprises four papers reporting results from a project studying the fear of flying phenomenon. Paper I is an evaluation study of a new percept-genetic instrument, the Flight Situation Test (FST). A group of 24 subjects with a fear of flying (FoF) and 19 controls (non-FoF) were tested. The test instrument turned out to be valuable in pinpointing differences between the groups, and was i

A Quick Test of cognitive speed is sensitive in detecting early treatment response in Alzheimer's disease

Introduction There is a great need for quick tests that identify treatment response in Alzheimer's disease (AD) to determine who benefits from the treatment. In this study, A Quick Test of cognitive speed (AQT) was compared with the mini-mental state examination (MMSE) in the evaluation of treatment outcome in AD. Methods 75 patients with mild to moderate AD at a memory clinic were assessed with

Determination of the adsorption site of a polyatomic adsorbate using vibrational spectroscopy and ab initio calculations: methoxy on Cu(100)

Using vibrational spectroscopy and ab initio electronic structure calculations of small metal cluster models we have determined the adsorption site of methoxy on Cu(100). The experimental vibrational frequencies are very well reproduced by the model cluster representing the four-fold hollow adsorption site in contrast to calculated frequencies for model clusters representing bridge and on-top adso

Increasing Time-Efficiency and Accuracy of Robotic Machining Processes Using Model-Based Adaptive Force Control

Machining processes in the industry of today are rarely performed using industrial robots. In the cases where robots are used, machining is often performed using position control with a conservative feed-rate, to avoid excessive process forces. There is a great benefit in controlling the process forces instead, so as to improve the time-efficiency by applying the maximum allowed force, and thus re

A longitudinal study of engineering students' approaches to their studies.

This longitudinal study draws on data from a larger project and examines how students' perceptions of their opportunities to influence their study environment may be enacted in approaches aimed at influencing their studies, and whether this changes during the course of their studies. Ten students from a 4.5-year Master's programme in Engineering were studied throughout their education by means of
