A Romance of Old Tasmania: Isabel Dick’s Wild Orchard

Isabel Dick’s historical romance novel Wild Orchard was published in 1946. There are very scarce references to Dick in the history of Tasmanian and Australian fiction and even less critical engagement with her work. Set almost two decades after the events of the 1820s, the atrocities of Van Diemen’s Land’s macabre past appear within the novel as echoes; the pages are haunted by the island’s histor

On Multilink Shadowing Effects in Measured V2V Channels on Highway

Shadowing from vehicles can degrade the performance of vehicle-to-vehicle (V2V) communication systems significantly. It is thus important to characterize and model the influence of common shadowing objects like cars properly. For multilink systems it is essential to model the joint effects on the different links. However, the multilink shadowing effects in V2V channels are not yet well understood.

New laser-based techniques for nanometre lithography and microscopy

This thesis describes the development of new laser-based techniques for nanometre lithography and microscopy. The potential of a non-intrusive scanned near-field optical microscope (SNOM) has been investigated. The probe consists of an optically trapped microscopic particle which is scanned in proximity to the object to be studied. Compared with conventional SNOM's, this probe would allow high-res

Antenna currents for optimal Q, superdirectivity, and radiation patterns using convex optimization

The high Q-factor (low bandwidth) and low efficiency make the design of small antennas challenging. Here, convex optimization is used to determine current distributions that give upper bounds on the antenna performance. Optimization formulations for maximal gain Q-factor quotient, minimal Q-factor for superdirectivity, and minimum Q for given far-field are presented. The effects of antennas embedd

Onset of mould growth – the effect of climate variability and different geographic locations

This paper presents a study on how climate conditions at numerous locations in Sweden affect the risk of onset of mould on wood sheltered outdoors. The results indicate that the risk is clearly higher in the south compared to the north of Sweden. These differences are mainly explained by colder and dryer winter periods in the north which is unfavorable for development of mould. The results also sh
