Online Communities: Visualization and Formalization
Online Communities: Visualization and Formalization Jonathan P. Bowen Museophile Limited, Oxford, UK [email protected] www.jpbowen.com Abstract. Online communities have increased in size and importance dramat- ically over the last decade. The fact that many communities are online means that it is possible to extract information about these communities and the con- nections between their members much more easily using software tools, despite their potentially very large size. The links between members of the community can be presented visually and often this can make patterns in the structure of sub-communities immediately obvious. The links and structures of layered com- munities can also be formalized to gain a better understanding of their modelling. This paper explores these links with some specific examples, including visualiza- tion of these relationships and a formalized model of communities using the Z notation. It also considers the development of such communities within the Com- munity of Practice social science framework. Such approaches may be applicable for communities associated with cybersecurity and could be combined for a better understanding of their development. 1 Introduction The development of collective human knowledge has always depended on communities. As communities have become more computer-based, it has become easier to monitor the activity of such interactions [7]. Recently the increasing use of online communities by the wider population (e.g., for social networking) has augmented the ways that com- munities can form and interact since geographical co-location is now much less critical than before the development of the Internet and the web [1,2]. -

Especialment, voldria donar les graciesa en Juan Carlos. Sempre m'has acompanyat. Sempre m'has ajudat. Sempre has estat allaquan t'he necessitat, ja fossis al meu costat o a milles enfora. Ara que nos veim cada dia, esper no te cansis de jo. T'estim! Molts coneixements previs he hagut de menester. Molts altres els he adquirit pel cam.L'escola, l'institut, la carrera i el mastera l'IIIA m'han aportat molts d'ells. Tambeel meu pas per l'empresa privada, per tot arreu s'apren. Els valors, en canvi, s'aprenen a casa. Els vaig aprendre a Menorca graciesals meus pares i tambeals meus germans. Papa! Mama! Me vau donar una infanciaimpressionant, envoltada d'un entorn ple de coses per experimentar sentint-me segura i protegida. Me vau deixar creixer,que formessa meva propia personalitat, que anesagafant responsabilitats, i que fos lliure de decidir per jo mateixa lo que ningumespodia decidir. Vau conar en jo i me vau nancar els estudis a Barcelona. Casi res! Moltes graciesper tot. Bep, amb tu vaig aprendre a enraonar, a donar mil voltes a ses coses i a poder veure-les des de diferents punts de vista. -

Spreading Excellence
IST-004527 ARTIST2 NoE Year 3 JPASE: Joint Programme of Activities for D3-Mgt-Y3 Spreading Excellence IST-004527 ARTIST2 Network of Excellence on Embedded Systems Design Spreading Excellence Artist2 Technical Coordinator: Bruno Bouyssounouse (Verimag) with inputs from all NoE participants The visibility of the ARTIST2 research effort in embedded systems design is worldwide. This is progressively creating a European embedded systems design community, and spreading the “artist culture” in all major research institutions. To ensure that the next generation of researchers will continue in this direction we, as a consortium, devote a great deal of effort to Spreading Excellence, in both academic and industrial circles. Furthermore, through our links with both core and affiliated partners, we are actively setting up permanents links between industry and public research, leveraging on existing partner collaborations with major industrial players in the area. This document shows that ARTIST2 has a strategic impact on the integration of multiple academic research communities, which are necessary to establish the new area of embedded systems design. 1 / 126 IST-004527 ARTIST2 NoE Year 3 JPASE: Joint Programme of Activities for D3-Mgt-Y3 Spreading Excellence Table of Contents 1.

I see a method as a set of principles to be used in the analysis of problems and in the synthesis of solutions to these problems. I see the analysis and synthesis to be based on techniques and tools. The principles are then about the selection and practical use of the analysis and synthesis techniques and tools — research must uncover these principles, techniques and tools. Software engineering textbooks must cover them.4 I see a good software development method to be one that provides for efficient development approaches resulting in efficient software that meets customers expectations (and only and exactly those) and software that is correct (that is satisfies its requirements). -
Completeness of Higher-Order Duration Calculus *
Completeness of Higher-Order Duration Calculus Zhan Naijun Lab. of Computer Science and Techonology, Institute of Software, the Chinese Academy of Sciences, Beijing, 100080, P.R. China [email protected] Abstract. In order to describe the real-time behaviour of programs in terms of Duration Calculus (DC), proposed by Zhou Chaochen, C.A.R. Hoare and A.P. Ravn in [3], which can specify real-time requirements of computing systems, quantifications over program variables are inevitable, e.g. to describe local variable declaration, to declare internal channel and so on. So a higher-order duration calculus (HDC) is established in [2]. This paper proves completeness of HDC on abstract domains by encod- ing HDC into a complete first-order two-sorted interval temporal logic (IL2 ). This idea is hinted by [9]. All results shown in this paper are done under the assumption that all program variables have finite variability. Keywords: duration calculus higher-order logic interval temporal logic completeness 1 Introduction In order to describe the real-time behaviour of programs in terms of DC, quan- tifications over program variables are inevitable, e.g. to describe local variable declaration and so on. So a higher-order duration calculus is established in [2]. In [2], a real-time semantics of local variables has been demonstrated, and some real-time properties of programs have been derived using HDC. In order to specify the behaviour of real-time programs, program variables Vi,i≥ 0 are introduced into HDC. Predicates of program variables, constants, and global variables, such as (V<3) and (V = x), are taken as states. -

When Shannon Met Turing
DOI: http://dx.doi.org/10.14236/ewic/EVA2017.9 Life in Code and Digits: When Shannon met Turing Tula Giannini Jonathan P. Bowen Dean and Professor Professor of Computing School of Information School of Engineering Pratt Institute London South Bank University New York, USA London, UK http://mysite.pratt.edu/~giannini/ http://www.jpbowen.com [email protected] [email protected] Claude Shannon (1916–2001) is regarded as the father of information theory. Alan Turing (1912– 1954) is known as the father of computer science. In the year 1943, Shannon and Turing were both at Bell Labs in New York City, although working on different projects. They had discussions together, including about Turing’s “Universal Machine,” a type of computational brain. Turing seems quite surprised that in a sea of code and computers, Shannon envisioned the arts and culture as an integral part of the digital revolution – a digital DNA of sorts. What was dreamlike in 1943, is today a reality, as digital representation of all media, accounts for millions of “cultural things” and massive music collections. The early connections that Shannon made between the arts, information, and computing, intuit the future that we are experiencing today. This paper considers foundational aspects of the digital revolution, the current state, and the possible future. It examines how digital life is increasingly becoming part of real life for more and more people around the world, especially with respect to the arts, culture, and heritage. Computer science.
