Lightweight Internet Traffic Classification - A Subject Based Solution with Word Embeddings

Internet traffic classification is a relevant and mature research field, anyway of growing importance and with still open technical challenges, also due to the pervasive presence of Internet-connected devices into everyday life. We claim the need for innovative traffic classification solutions capable of being lightweight, of adopting a domain-based approach, of not only concentrating on application-level protocol categorization but also classifying Internet traffic by subject. To this purpose, this paper originally proposes a classification solution that leverages domain name information extracted from IPFIX summaries, DNS logs, and DHCP leases, with the possibility to be applied to any kind of traffic. Our proposed solution is based on an extension of Word2vec unsupervised learning techniques running on a specialized Apache Spark cluster. In particular, learning techniques are leveraged to generate word-embeddings from a mixed dataset composed by domain names and natural language corpuses in a lightweight way and with general applicability. The paper also reports lessons learnt from our implementation and deployment experience that demonstrates that our solution can process 5500 IPFIX summaries per second on an Apache Spark cluster with 1 slave instance in Amazon EC2 at a cost of $ 3860 year. Reported experimental results about Precision, Recall, F-Measure, Accuracy, and Cohen's Kappa show the feasibility and effectiveness of the proposal. The experiments prove that words contained in domain names do have a relation with the kind of traffic directed towards them, therefore using specifically trained word embeddings we are able to classify them in customizable categories. We also show that training word embeddings on larger natural language corpuses leads improvements in terms of precision up to 180%.

Constructing, Creating and Contesting Cityscapes. A Socio-Anthropological Approach to Urban Transformation in Southern Xinjiang, People’s Republic of China

This manuscript is based on a PhD thesis submitted at the Institute of Social Anthropology at the University of Bern in 2014. The dissertation was part of the research project „Xinjiang Uyghur Autonomous Region and Chinese Territoriality. The Development of Infrastructure and Han Migration into the Region“ under the supervision of Prof. Dr. Heinzpeter Znoj and financed by the Swiss National Science Foundation SNSF. Madlen Kobi analyzes the architectural and socio-political transformation of public places and spaces in rapidly urbanizing southern Xinjiang, P.R. China, and in doing so pays particular attention to the cities of Aksu and Kaxgar. As the Xinjiang Uyghur Autonomous Region lies in between China and Central Asia, it is especially characterized by differing political, cultural, and religious influences, and, furthermore, due to its being a multiethnic region, by multiple identities. One might expect cultural and social identities in this area to be negotiated by referring to history, religion, or food. However, they also become visible by the construction and reconstruction, if not demolition, of public places, architectural landmarks, and private residences. Based on ethnographic fieldwork performed in 2011 and 2012, the study explores everyday life in a continuously transforming urban environment shaped by the interaction of the interests of government institutions, investment companies, the middle class, and migrant workers, among many other actors. Here, urban planning, modernization, and renewal form a highly sensitive lens through which the author inspects the tense dynamics of ethnic, religious, and class-based affiliations. She respects varieties and complexities while thoroughly grounding unfolding transformation processes in everyday lived experiences. The study provides vivid insights into how urban places and spaces in this western border region of China are constructed, created, and eventually contested.

Selecting Contexts. One Method of Selecting Contexts for Theatre Historiography

In principle, the world and life itself are the contexts of theatrical events. The term context is broad and thus seems hardly usable. It only makes sense to use the term when terminologies and methodologies determine which parts of their contexts are to be incorporated and analysed for which theatrical event. This presentation exemplifies a method which is particularly suitable for sensibly selecting the most important contexts for research in theatre history. The complexity of the representation increases continuously from The Presentation of Self in Everyday Life to Brecht’s “Street Scene” and “Everyday Theatre”, portrayals of rulers in feasts and parades to Hamlet productions by the Royal Shakespeare Company or a Wagner opera in Bayreuth. The different forms of theatre thus constitute a continuum which spans from “everyday theatre” to “art theatre”. The representation of the world in this continuum is sometimes questioned by the means of theatre, for example when Commedia dell’arte takes a critical stance towards the representative theatre of the humanists or when playful devices such as reversal, parody and fragmentation challenge the representative character of productions, which is applied by the Vice character for instance. There is a second component that has an impact on the continuum without a theatrical device: attitude, opinion, norms and bans which originate from society. As excerpts of contexts, they refer to single forms of theatre in the continuum. This results in a complex system of four components which evolves from the panorama between the antipodes “everyday theatre” and “art theatre” as well as both spheres of influence of which only one uses theatrical devices. All components interact in a specific time frame in a specific place in a specific way in each case, which can then be described as the theatricality in this time frame. This presentation will deal with what the concept is capable of doing.

Tradesperson or artist? A critical exploration of chefs' job satisfaction and turnover

The interest in experiential and embodied aspects of brand and other product usage is under-represented in tourism orientated research, which generally falls to develop a contextualised understanding of the relationships between products and consumers, and within this in particular, considerations of individuality and self, embodiment, emotion and sensation. Aiming to `reverse the causality' (Lannon and Cooper 1983:201) of consumption focused tourism research, in this paper, I draw on the tourism experiences of Audrey, a participant in a larger study to reveal how, rather than just `consuming', tourism consumers interpret the meaning and values in a wide range of products and objects, weaving individual, rich, sensory, embodied experiences which are informed by the interactions and relationships with activities and products, and by their own personalities, past experiences and aspirations. Audrey is highly conscious of her self and of elsewhereness, hers are fragile, self-indulgent, tactile experiences which offer the freedom to step out of everyday life roles into other time and situational spheres where environment, objects and sensory stimulation are paramount.

Notes on the history of the mobile phone in Australia

The first automatic mobile phone service was launched in Australia in 1981, with the first cellular mobile service following in 1987. In 2003 there were over 14.5 million mobile phone subscribers, and the technology had become central to everyday life and culture. Despite the significance of mobile phones, little has been written about their Australian histories. This paper offers some notes on the history of mobile telecommunications in Australia. As well as reviewing the development of the mobile phone in Australia, it looks at the cultural representation of this technology.

Influencing the perceived emotions of music with intent

Music is an immensely powerful affective medium that pervades our everyday life. With ever advancing technology, the reproduction and application of music for emotive and information transfer purposes has never been more prevalent. In this paper we introduce a rule-based engine for influencing the perceived emotions of music. Based on empirical music psychology, we attempt to formalise the relationship between musical elements and their perceived emotion. We examine the modification to structural aspects of music to allow for a graduated transition between perceived emotive states. This engine is intended to provide music reproduction systems with a finer grained control over this affective medium; where perceived musical emotion can be influenced with intent. This intent comes from both an external application and the audience. Using a series of affective computing technologies, an audience’s response metrics and attitudes can be incorporated to model this intent. A generative feedback loop is set up between the external application, the influencing process and the audience’s response to this, which together shape the modification of musical structure. The effectiveness of our rule system for influencing perceived musical emotion was examined in earlier work, with a small test study providing generally encouraging results.

Sobre os cumes dos montes sacrificam Um estudo em Oseias 4,4-19

A tese divide-se em três capítulos: no primeiro, estudam-se a forma e o lugar de Oseias 4,4-19; no segundo, os conteúdos da passagem bíblica em foco; e, no terceiro capítulo, abordam-se outros textos do livro de Oseias que corroborem com a tese apresentada a partir da análise de Oseias 4,4-19, feita nos capítulos anteriores. Estudar Oseias é abrir possibilidade de dar voz, novamente, ao antigo profeta e ouvir-lhe falar para a sua situação de israelita e representar seus irmãos na dura realidade da vida em Israel no século 8º a. C. O trecho selecionado para estudo apresenta muitos aspectos dessa vida, caracterizada por declarações, expressões e imagens vívidas, como a montar um quadro do seu cotidiano. E aqui reside o ponto nevrálgico das reflexões sobre a passagem bíblica: um cotidiano condenado pelo profeta, em nome de Javé, por encobrir, por meio de suas aparências e justificativas, o abuso de pessoas, até mediante a religião. O profeta não condena os israelitas, tampouco as mulheres (4,13-14), mas os senhores do poder , dentre os quais estão os sacerdotes, por deixarem suas responsabilidades em favor do povo de Javé para seguirem seus próprios interesses, a custa desse mesmo povo. Para reforçar suas acusações (e lamentações, vv.6 e 11), Oseias se utiliza, metaforicamente, de termos como a raiz hebraica hnz znh e palavras derivadas, a qual é entendida nesta tese como ser ou tornar-se independente , pois aqueles que mandam no país, têm procedido de maneira autônoma, longe das tradições javistas pautadas no verdadeiro conhecimento (tu^D^ da at) e na instrução (hr*oT torah) de deus, que podem ser percebidos na prática do direito (fP*v=m! mispat) e da solidariedade (ds#j# hesed). Oseias não pretende desmascarar cultos idolátricos pela simples preocupação de preservar ideias religiosas, e nem se preocupa com práticas, mesmo as de prostituição, por questões moralistas. Ele protesta contra a realidade de uma vida condenada ao esmagamento por grupos que, mostrando-se tão religiosos, tornaram-se, de fato, independentes do Javé do êxodo, do Javé dos pobres.
