1. Using False Alarms when Developing Automotive Active Safety Systems
Sammanfattning : This thesis develops and tests an empirical method to quantifying drivers’ level of acceptance for alerts issued by automotive active safety systems. The method uses drivers’ subjective level of acceptance for alerts that are literally false alarms as a measure to guide the development of alerting criteria that can be used by active safety systems.

2. Univariate and Multivariate Surveillance of Outbreaks
Sammanfattning : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision. LÄS MER
3. Understanding Intrusion Detection Through Visualisation
Sammanfattning : With the ever increasing use of computers for critical systems, computer security, the protection of data and computer systems from intentional, malicious intervention, is attracting much attention. Among the methods for defence, intrusion detection, i.e. LÄS MER
4. Securing the Foundations of Practical Information Flow Control
Sammanfattning : Language-based information flow control (IFC) promises to secure computer programs against malicious or incompetent programmers by addressing key shortcomings of modern programming languages. In spite of showing great promise, the field remains under-utilised in practise. LÄS MER
5. Computer-based detection of cardiac arrhythmias : methods and systems
Sammanfattning : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. LÄS MER
