title: Cycloaurated gold(III) complexes with monoanionic thiourea ligands

authors: Smith, Tiffany Sharee

subjects: gold complexes

abstract: Using a simple one-pot procedure, reaction of cycloaurated gold(III) dihalide complexes [LAuCl₂] (L = 2-benzylpyridyl, 2-anilinopyridyl) with trisubstituted thioureas PhNHC(S)NR₂ (R = Me, Cy) and Me3N in methanol, followed by addition of excess NaBPh₄ gave the salts [Lau{SC(-NR₂)NPh}]⁺BPH₄⁻ containing N,S-chelated thiourea monoanion ligands. The compounds were obtained in good yields, and were characterised by ESI MS, elemental microanalysis and in two cases by X-ray structure determinations. The series of complexes was extended by additional microscale reactions of LAuCl₂ complexes (L = 2-benzylpyridyl, 2-anilinopyridyl, 2-benzoylpyridyl or picolinamide) with a wide range of trisubstituted thioureas, with products identified by ESI MS.

title: Development and characterisation of an easily configurable range imaging system

authors: Jongenelen, Adrian P.P.

subjects: range imaging

abstract: Range imaging is becoming a popular tool for many applications, with several commercial variants now available. These systems find numerous real world applications such as interactive gaming and the automotive industry. This paper describes the development of a range imaging system employing the PMD-19 k sensor from PMD technologies. One specific advantage of our system is that it is extremely customisable in terms of modulation patterns to act as a platform for further research into time-of-flight range imaging. Experimental results are presented giving an indication of the precision and accuracy of the system, and how modifying certain operating parameters can improve system performance.

title: Language switching in a digital library: Does it make a difference if the default language is set to Maori?

authors: Keegan, Te Taka Adrian Gregory

abstract: In this paper we investigate the effect of default interface language on usage patterns of the Niupepa digital library (a collection of historic Māori language newspapers), by switching the default interface language between Māori and English in alternate weeks.
Transaction analysis of the Niupepa collection logs indicates that changing default language affects the length of user
sessions and the number of actions within sessions, and that the English language interface was used most frequently.
