Ubicomp, Touch and Gaze by Hans Gellersen

Abstract:
Touch input and two-handed interaction were intensively studied in the mid 80′s but it’s taken 20 years for these ideas to emerge in the mainstream, with the advent of multi-touch interfaces. Gaze has been studied for almost as long as interaction modality and appears on the brink of wider use. This talk will present recent work that reconsiders touch and gaze to address challenges in ubiquitous computing: interaction across personal devices and large displays, and spontaneous interaction with displays using our eyes only.

Bio:
Hans Gellersen is a Professor of Interactive Systems in the School of Computing & Communications at Lancaster University. His research interests are in ubiquitous computing and systems and technologies for human-computer interaction. He has contributed on topics including location, context and activity sensing, device association and cross-device interaction, and interfaces that blend physical and digital interaction. In his recent work, he is particularly interested in eye movement analysis: as a source of contextual information on human activity, interest and well-being; and as a resource for interaction beyond the lab. Hans is closely involved with the UbiComp conference series which we founded in 1999, and served on the Editorial Boards of Personal and Ubiquitous Computing, and IEEE Pervasive Computing. He holds a PhD from Karlsruhe University.

Evaluation of Network Resilience and Survivability: Analysis, Simulation, Tools, and Experimentation by James P. G. Sterbenz, ITTC, University of Kansas

As the Internet becomes increasingly important to all aspects of society, the consequences of disruption are increasingly severe. Thus it is critical to increase the resilience and survivability of the future networks in general, and the Internet in particular. We define resilience as the ability of the network to provide desired service even when the network is challenged by attacks, large-scale disasters, and other failures. Resilience subsumes the disciplines of survivability, fault-tolerance, disruption-tolerance, traffic-tolerance, dependability, performability, and security. After an introduction to the disciplines and challenges to network resilience, this presentation will discuss analytical, simulation, and experimental emulation techniques for understanding, evaluating, and improving the resilience of the Future Internet. This includes a multilevel state-space based approach that plots network service delivery against operational state that is the basis for both mathematical- and simulation-based analysis, and graph-theoretic complex-system approaches that embed fundamental properties such as redundancy and diversity into all aspects of network structure, mechanism, and protocols. A set of tools to help in this analysis has been developed: KU-LoCGen (Location and Cost-Constrained Topology Generation), KU-TopView (Topology Viewer), and KU-CSM (Challenge Simulation Module). Plans to experimentally evaluate resilience include using the international programmable testbed GpENI: Great Plains Environment for Network Innovation. A new composable, cross-layered resilient transport protocol (ResTP) and geodiverse multipath routing protocol (GeoDivRP) are being developed.

Evolution of our existing institutional research information infrastructure : a facilitator for Open Science?

Anna Clements, Head of Research Data and Information Services, University of St Andrews.

Open Science’ seems to be one of the hottest topics around with organisations and funders from the G8 downwards stressing the importance of open data in driving everything from global innovation through to more accountable governance; not to mention the more direct possibility that non-compliance could result in research grant income drying up.
Here at St Andrews we have had an institutional research information system (CRIS) since 2006 which has evolved in tandem with the rapidly changing research policies and slower cultural shifts towards more and more open access to research outputs, outcomes and impact. But, we now face, perhaps, the biggest challenge so far in determining the extent to which Institutional infrastructure and services can support this transition to an ‘open by default’ culture. I will argue that this challenge cannot be met without researchers engaging with the debate and driving the agenda forward with the support services here at St Andrews – there is a joint responsibility very clearly articulated in the EPSRC policy framework on research data. So there will be some suggestions on what we could do by building on our existing infrastructure, including examples of best practice from elsewhere, but also an invitation to the audience for suggestions on how to respond to this incessant and increasing clamour for access to research outputs and, in particular, research data.

The Interaction of Representation and Reasoning by Professor Alan Bundy, University of Edinburgh

These lectures will take place in Lower College Hall, North Street. The lectures will discuss the close relationship between how knowledge and problems may be represented and how people and computers use these representations to guide their reasoning about the problems.

10.00 1. Title: The Interaction of Representation and Reasoning

Abstract: Successful reasoning is dependent on appropriate representation of both knowledge and of successful methods of reasoning. A change of representation can change an intractable problem into an easy one. Failures of reasoning can suggest changes of representation. Reasoning failures can, for instance, take the form of proofs of false conjectures, failures to prove true conjectures or inefficient inference. I will illustrate these interactions by drawing on work in my research group.

11.30 2. Title: Theory Evolution in Physics

Abstract: We investigate the problem of automatically repairing a faulty Physics theory when it conflicts with experimental evidence. We introduce novel strategies for fault diagnosis and for representation repair. Diagnosis and repair are composed into general-purpose repair plans. We will illustrate this with two such plans, where theory and experiment conflict over (a) the value and (b) the dependence of a function, respectively. We represent both physical concepts and the repair plans using higher-order logic. This is because many physical concepts are most naturally represented as higher-order functions and because polymorphic higher-order functions are required to enable the repair plans to be applied to diverse situations.

14.00 3. Title: Reformation: A Domain-Independent Algorithm for Theory Repair

Abstract: We describe and invite discussion on work in progress on reformation, a new algorithm for the automated repair of faulty logical theories. A fault is revealed by a reasoning failure: either the proof of a false theorem or the failure to prove a true conjecture. Repair suggestions are systematically extracted via analysis of the attempted unification of two formulae. These suggestions will either block an unwanted but successful unification or unblock a wanted but failed unification attempt. In contrast to traditional belief revision and abduction mechanisms, the repairs are to the language of the theory as well as to the deletion or addition of axioms.

Some Limits of Language: A Perspective from Formal Grammars and Languages by Prof Arvind Joshi, School of Engineering and Applied Science, University of Pennsylvania, USA

Limits of language can be studied from various perspectives such as morphology, syntax, and semantics, among others. At the syntactic level, one direction that has been pursued very actively is via the theory of formal languages, beginning with the so-called Chomsky hierarchy. In this hierarchy, the finite state languages (regular languages) and the context free languages (CFL) have been studied very extensively, leading to many important results relevant to syntax as well as parsing. At the same time, inadequacy of these two classes of grammars (languages) for capturing natural languages has been well documented by now.
A careful look at the pumping lemma for context free languages led to the discovery of the so-called tree adjoining grammars (TAG) and to the notion of mildly context sensitive languages (MCSL), which has served as a framework for showing equivalences among other systems (such as Combinatory Categorial Grammars, CCG and Head Grammars (HG), for example). This has led to a deeper understanding of the limits of language, more specifically, by trying to provide an answer to the question: how far do we need to be beyond CFL to achieve syntactic adequacy.
I will try to describe some of this recent work by a number of researchers in the past few years.

Aravind Joshi did his undergraduate work in India and his graduate work at the University of Pennsylvania in Electrical Engineering, while simultaneously attending some courses in Linguistics at the same University. Since 1961 he has been a faculty member in the Department of Computer and Information Science and the Department of Linguistics. At present, he is a Professor of Computer and Cognitive Science and a Member of the Institute for Research in Cognitive Science.
Besides working on some problems in the mathematics of language, at present, he is involved in a project on discourse annotation, jointly with Bonnie Webber (Edinburgh U.) and Rashmi Prasad (U. Wisconsin), for creating the Penn Discourse Treebank (PDTB).
