    • Randomized Load Balancing on Networks with Stochastic Inputs 

      Cai, Leran; Sauerwald, Thomas Michael (Leibniz International Proceedings in Informatics, 2017-07-14)
      Iterative load balancing algorithms for indivisible tokens have been studied intensively in the past. Complementing previous worst-case analyses, we study an average-case scenario where the load inputs are drawn from a ...
    • Randomized rumor spreading in dynamic graphs 

      Giakkoupis, G; Sauerwald, Thomas Michael; Stauffer, A (2014-01-01)
    • Rapid codesign of a soft vector processor and its compiler 

      Naylor, Matthew; Moore, Simon William (IEEE, 2014-10-15)
      Despite a decade of activity in the development of soft vector processors for FPGAs, high-level language support remains thin. We attribute this problem to a design method in which the high-level vector programming interface ...
    • Real-time noise-aware tone mapping 

      Eilertsen, G; Mantiuk, Rafal Konrad; Unger, J (ACM, 2015-11-01)
      Real-time high quality video tone mapping is needed for many applications, such as digital viewfinders in cameras, display algorithms which adapt to ambient light, in-camera processing, rendering engines for video games ...
    • Reasoning with concept diagrams about antipatterns in ontologies 

      Shams, Zohreh; Jamnik, Mateja; Stapleton, G; Sato, Y (2017-01-01)
      © Springer International Publishing AG 2017. Ontologies are notoriously hard to define, express and reason about. Many tools have been developed to ease the ontology debugging and reasoning, however they often lack ...
    • Recognising enthymemes in real-world texts: A feasibility study 

      Razuvayevskaya, Olesya; Teufel, Simone Heidi
      We present a feasibility study for the task of finding and expanding enthymemes, i.e, arguments with missing propositions, in real-world texts. We split the task into three subtasks: 1. finding the beginning and the end ...
    • Reconfigurable Network Systems and Software-Defined Networking 

      Zilberman, Noa; Rotsos, Charalampos; Moore, Andrew William (IEEE, 2015-06-11)
      Modern high-speed networks have evolved from relatively static networks to highly adaptive networks facilitating dynamic reconfiguration. This evolution has influenced all levels of network design and management, introducing ...
    • Red Button and Yellow Button: Usable Security for Lost Security Tokens 

      Goldberg, I; Jenkinson, G; Llewellyn-Jones, David; Stajano, Francesco Mario
      Currently, losing a security token places the user in a dilemma: reporting the loss as soon as it is discovered involves a significant burden which is usually overkill in the common case that the token is later found behind ...
    • RELPRON: A Relative Clause Evaluation Data Set for Compositional Distributional Semantics 

      Rimell, Laura Dorfman; Maillard, Jean; Polajnar, Tamara; Clark, Stephen Christopher (MIT Press, 2016-12-01)
      This article introduces RELPRON, a large data set of subject and object relative clauses, for the evaluation of methods in compositional distributional semantics. RELPRON targets an intermediate level of grammatical ...
    • RELPRON: A Relative Clause Evaluation Dataset for Compositional Distributional Semantics 

      Rimell, Laura; Maillard, Jean; Polajnar, Tamara; Clark, Stephen (MIT Press, 2016-09-28)
      This article introduces RELPRON, a large dataset of subject and object relative clauses, for the evaluation of methods in compositional distributional semantics. RELPRON targets an intermediate level of grammatical complexity ...
    • REPAIR: Hard-Error Recovery via Re-Execution 

      Soman, Jyothish; Miralaei, Negar; Mycroft, Alan; Jones, Timothy Martin (IEEE, 2015-10-14)
      Processor reliability at upcoming technology nodes presents significant challenges to designers from increased manufacturing variability, parametric variation and transistor wear-out leading to permanent faults. We present ...
    • Resolving data center power bill disputes: the energy-performance trade-offs of consolidation 

      Chatzipapas, Angelos; Pediaditakis, Dimosthenis; Rotsos, Charalampos; Mancuso, Vincenzo; Crowcroft, Jon; Moore, Andrew W. (2015-06-09)
      In this paper we challenge the common evaluation practices used for Virtual Machine (VM) consolidation, such as simulation and small testbeds, which fail to capture the fundamental trade-off between energy consumption and ...
    • Responsibility and Tangible Security: Towards a Theory of User Acceptance of Security Tokens 

      Payne, Jeunese; Jenkinson, Graeme; Stajano, Frank; Sasse, M. Angela; Spencer, Max (Internet Society, 2016)
      Security and usability issues with passwords suggest a need for a new authentication scheme. Several alternatives involve a physical device or token. We investigate one such alternative, Pico: an authentication scheme that ...
    • Reverse engineering Flash EEPROM memories using Scanning Electron Microscopy 

      Courbon, Franck Rene; Skorobogatov, Sergei Petrovich; Woods, C
      In this article, a methodology to extract Flash EEPROM memory contents is presented. Samples are first backside prepared to expose the tunnel oxide of floating gate transistors. Then, a Scanning Electron Microscope (SEM) ...
    • Revolutionising Computing Infrastructure For Citizen Empowerment 

      Zilberman, Noa (Zenodo, 2017-09-04)
      The world has dramatically changed over the last decade. Almost every aspect of our lives is being digitally monitored: from our social networks activity, through online shopping habits to healthcare and financial records. ...
    • Robust Registration of Dynamic Facial Sequences. 

      Sariyanidi, Evangelos; Gunes, Hatice; Cavallaro, Andrea (IEEE, 2017-04)
      Accurate face registration is a key step for several image analysis applications. However, existing registration methods are prone to temporal drift errors or jitter among consecutive frames. In this paper we propose an ...
    • The role of gene fusions in the evolution of metabolic pathways: the histidine biosynthesis case 

      Unknown author (2007-08-16)
