11. New Instrumentation for Forensic Applications : Automatic Fiber Detection and Breath Alcohol Measurements
Sammanfattning : Two forensic instruments have been developed and evaluated with respect to basic characteristics. One instrument is used for automatic fiber detection and the other for breath alcohol measurement. LÄS MER
12. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern
Sammanfattning : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

13. Cyanide in breath as a marker for cyanide poisoning
Sammanfattning : Approximately 120 people die every year due to fires in Sweden. A majority of the fire victims die due to toxic fire gases. Carbon monoxide is often thought to be the major cause of death. Still, another very toxic fire gas, hydrogen cyanide, is formed when materials containing nitrogen burn, e. LÄS MER
14. Modeling, Analysis and Design of Wireless Sensor Network Protocols
Sammanfattning : Wireless sensor networks (WSNs) have a tremendous potential to improve the efficiencyof many systems, for instance, in building automation and process control.Unfortunately, the current technology does not offer guaranteed energy efficiencyand reliability for closed-loop stability.

15. Integrating Biosensors for Air Monitoring and Breath-Based Diagnostics
Sammanfattning : The air we breathe is the concern of all of us but nevertheless we only know very little about airborne particles, and especially which biological microorganisms they contain. Today, we live in densely populated societies with a growing number of people, making us particularly vulnerable to air transmission of pathogens. LÄS MER
