11. ESR dosimetry in the radiation therapy dose range : development of dosimetry systems and sensitive dosimeter materials
Sammanfattning : ESR dosimetry with L-α-alanine as a dosimeter material is a well known and frequently used method for measuring high absorbed doses, for example at sterilisation and food irradiation. The increased sensitivity of modem spectrometers and an increased knowledge of the radiochemical properties of alanine have lowered the detection limit of ESR/alanine dosimetry to the dose range relevant for radiation therapy.

12. Size matters : RNA silencing processes in Phytophthora infestans
Sammanfattning : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. LÄS MER
13. Mobile robot navigation and map generation using range measurements
Sammanfattning : This thesis is on mobile robot navigation using range sensors. The two sensors types used are time-of-flight lasers and sheet-of-light range cameras, both giving densely spaced range measurements. Map generation and navi gation are achieved in indoor environments, even when there are lots of disturbing objects giving cluttered range measurements. LÄS MER
14. Synthesis of Controllers from a Range of Controller Architectures
Sammanfattning : An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms.

15. Modeling rating curves from close-range remote sensing data : Application of laser and acoustic ranging instruments for capturing stream channel topography
Sammanfattning : A rating curve provides a functional relationship between water height (i.e. stage) and discharge at a specified cross-section in a river. Used in combination with a time series of stage, rating curves become one of the central components for generating continuous records of streamflow. LÄS MER
