title: Design of twin foldable and tiltable rotors flight vehicle model

authors: Zhang, Ziqian

abstract: With the increasing number of private cars, traffic congestion is getting worse. Compared to the ground, there is a wider space in the sky due to its three-dimensional space. In consideration of this, flight vehicles would be one of the best ways to solve the traffic problem on the ground. 

A new concept of the structure for the flight vehicle has been presented in this thesis. It has two rotors with folding mechanisms to provide lift. The two rotors could be folded to reduce the size when it is in the car mode. Also because of the twin rotors design, the structure of the rotor head becomes simpler than usual helicopter main rotor head. Moreover, by using some gearboxes, it makes the flying car just using one motor to power the two rotors. The use of these gearboxes can also simplify the structure of the rotor head. Due to the research of this concept is in the initial stage, thus, the project just made a model, not a real flying car to verify the feasibility of the concept. What is more, a method to control the model has been shown in this thesis by using a normal controller. This thesis focuses on the process of making the flight vehicle model including calculation, mechanical design, implementation and control method.

title: Persistence in mutual fund returns: New Zealand evidence

authors: Hooper, Keith

subjects: mutual fund returns

abstract: Many studies have discussed mutual funds performance, especially about the persistence of excess returns. Regression is the most common method to be used to research the fund persistence. Dutta (2002) proposes a simpler approach – a direct annual examination of whether a fund beats a market proxy or not, to research the persistence in American mutual fund returns. In this study, authors use a similar methodology to analyse New Zealand growth mutual funds. In addition, a statistically robust method is juxtaposed as a comparison. The study finds that the most of the funds sampled during the period 1996-2003 are unable to better the benchmark of the world index.

title: Microsoft Translator Hub for Māori language

authors: Keegan, Te Taka Adrian Gregory

subjects: computer science

abstract: Recent improvements in Machine Translation (MT) software has opened new possibilities for applications of automatic language translation. But can these opportunities exist for the smaller, minority languages of the world? Training data was collected for the language pair of Māori and English which was used to build an MT system using Microsoft’s Translator Hub software. A comparative analysis was undertaken with this system and Google Translate. Various MT metrics and analysis software was considered before deciding to use the Asiya toolkit to undertake the comparative analysis. Māori language experts were also used to provide a human perspective on the output translations. The overall results showed no significant difference in the translation quality produced by the two systems. Despite some misgivings around the accuracy of the translations these results do show promise for MT usage by minority languages.
