title: Comparing anomaly detection methods in computer networks

authors: Löf, Andreas

subjects: computer science

abstract: This work in progress outlines a comparison of anomaly detection methods that we are undertaking. We are comparing different types of anomaly detection methods with the purpose of achieving results covering a broad spectrum of anomalies. We also outline the datasets that we will be using and the metrics that we will use for our evaluation.

title: Chitosan: A review of sources and preparation methods

authors: Kou, Shijie

subjects: Science & Technology

abstract: This review aims to explore different sources of chitin and methods of chitosan production with industrial consideration. This article first discussed different sources of chitin for industrial scale production, with considerations given to both their environmental impacts and commercialization potential. Secondly, this article reviews the two categories of chitosan preparation – chemical methods and biological methods - based on existing publications which used lobster by-products as a feedstock source. The mechanisms of the chemical methods are firstly summarized, and then the different chemical agents and reaction parameters used are discussed. Next, both enzymatic and fermentation-based approaches are reviewed under biological methods and compared with chemical methodologies, with lactic fermentation methods as the major focus. This article concludes that lobster cephalothorax could be an ideal source for chitosan preparation on an industrial scale; and chemical methods involve simpler processing overall, while produce chitosan with stronger bioactivities because of lower molecular weight (MW) and higher degree of deacetylation (DD) achieved by the products. Moreover, due to biological methods inevitably necessitating further chemical processing, an approach involving some unconventional chemical methods has been regarded as a more suitable strategy for industrial scale chitosan production.

title: The piano as cultural symbol in colonial New Zealand

authors: Moffat, Kirstine

subjects: piano

abstract: The piano was an important cultural symbol in colonial New Zealand, yet although there is a significant body of international scholarship on the social and cultural history of the instrument in Britain, America, Canada, Norway, Spain and India there is a dearth of scholarly criticism relating to New Zealand. Research to redress this absence has revealed that the piano was central to settler culture, demonstrating a migrant desire to replicate the known and familiar but also highlighting settler innovations and an emerging nationalism. International connections between New Zealand, Britain, Western Europe, America and Australia are also apparent in relation to migrant patterns, the importation of instruments and sheet music and networks of musical performance and study. The instrument played a role in the complex dynamic of cultural encounter between Maori and settler, with an initial indigenous negativity and bemusement giving way to an interest in the piano and an appropriation of the instrument into Maori cultural contexts and spaces, including the marae. Prevailing perceptions of gender roles and identity are also challenged by research on the piano. Likewise, an examination of piano and class reveals that the instrument was popular with New Zealanders from all socio-economic backgrounds.
