We have collected polarimetric ice sounding radar data on Brunt, George VI and Ronne ice shelves using a vector network analyser as a continuous wave step-frequency radar. Being a wideband phase sensitive instrument, the radar allowed the vectorial nature of the interaction between radio waves and the ice and reflecting surface to be explored. Single crystals of ice are birefringent not only at...

A 29-year-old male presented at the emergency department of our hospital in a confused state. He had a history of psychoses and substance abuse. Physical examination revealed hyperventilation and abdominal tenderness. Blood gas analysis in the emergency department using an ABL 725 Radiometer analyser showed a severe metabolic acidosis with massive lactate elevation. Lactate acidosis due to mese...

In this thesis a novel measurement setup and thru-reflect-line (TRL) calibration kit for vector network analyser (VNA) measurements at 220GHz to 325GHz (WR-03) is presented. Measurements on passive membrane circuit devices under test (DUTs) show improvement in the S-parameters compared to a waveguide integrated membrane circuit setup in previous work, especially in reducing the ripples and incr...

In order to combat the state space explosion resulting from explicit-state model checking of software, we investigate the use of a parameterised boolean equation system (Pbes) to solve on-the-fly (i.e., with incremental construction of the program state space) influence analysis of program variables w.r.t. Application Programming Interface (Api) calls executed in the program. The static analysi...

In this study the classification performance of 2 machine learning methods and 2 sound representations schemes are compared, having the focus on short impact like sounds: Footsteps have been classified according to the material of the floor and the shoe type. The gammatone auditory filter bank is a spectral analyser, that converts a given signal into a multi-channel simulation of the basilar me...

A study on radiation losses in conducting polymer nanocomposites, namely La-Co-substituted barium hexaferrite and polyaniline, is presented. The study was performed by means of a vector network analyser, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, electron spin resonance spectroscopy and a vibrating sample magnetometer. It is found that the maxi...

We present details of a new high-field/high-frequency EPR technique, and its application to measurements of singlemolecule magnets (SMMs). By using a quasi-optical set-up and microwave sources covering a continuous frequency range from 170 to 600 GHz; in conjunction with a millimetre-wave vector network analyser, we are able to measure EPR to high magnetic fields. For example, a g 1⁄4 2 system ...

High spatial resolution 3-D SAR imagery was recorded by the UK’s Natural Environment Research Council GB-SAR Microwave Measurement Facility at the University of She eld. X-band VV polarisation measurements were made using a near-Ž eld monostatic imaging system inside an anechoic chamber. The measurement process employs vector network analyser techniques to sample backscatteredsignalsover a 2-D...

In this paper we present a dependency analyser able to compute syntax recognition and analysis according to dependency grammars. Analyser is able to deal with nonprojective constructions, it has means to express the level of word-order freedom and its limitations. Level of word-order freedom and level of robustness (correctness) of sentences can be given as parameters of the analysis. Data and ...

The ENGTWOL morphological analyser is a 55,000 entry Koskenniemi-style morphological description of English that assigns all recognised input word forms with all possible morphological readings as a disjunctive list. Those words not recognised by the ENGTWOL analyser are analysed by a heuristic module; part-ofspeech readings are assigned on the basis of the form of the word (endings etc.). The ...
