  • Development and Evaluation of a Device for the Haptic Rendering of Rotatory Car Doors 

    Strolz M; Groten R; Peer A; Buss M (2011)
    Virtual prototyping of car doors enhanced with haptic feedback is a promising way to decrease the number of physical prototypes. We clarify, correct, summarize, and extend our previous work on the haptic simulation of car ...
  • DIEL Demo 

    Forcheri, P; Dodero, G; Di Cerbo, F (Scuola IaD : F&D, 2009)
    In this demo, we would like to show how cooperative learning features have been added to the Moodle LMS, creating a virtual environment called DIEL.
  • DigitHist: a Histogram-Based Data Summary with Tight Error Bounds 

    Shekelyan M; Dignös A; Gamper J (2017)
    We propose DigitHist, a histogram summary for selectivity estimation on multi-dimensional data with tight error bounds. By combining multi-dimensional and one-dimensional histograms along regular grids of different ...
  • Discovering the Top-k Unexplained Sequences in Time-Stamped Observation Data 

    Albanese, M; Molinaro, C; Persia, F; Picariello, A; Subrahmanian, VS (2014)
    There are numerous applications where we wish to discover unexpected activities in a sequence of time-stamped observation data—for instance, we may want to detect inexplicable events in transactions at a website or in video ...
  • A distributed architecture for policy-customisable multi-tenant Processes-as-a-Service 

    Wang MX; Bandara KY; Pahl C (2016)
    Service-based business processes are often developed and deployed by single organizations. In distributed, shared resource environments like the cloud on the other hand, consumers share resources owned by cloud providers. ...
  • Distribution pattern-driven development of service architectures 

    Barrett R; Pahl C (Technische Universitaet Graz, 2009)
    Distributed systems are being constructed by composing a number of discrete components. This practice is particularly prevalent within the Web service domain in the form of service process orchestration and choreography. ...
  • Distributional semantic pre-filtering in context-aware recommender systems 

    Codina V; Ricci R; Ceccaroni L (2016)
    Context-aware recommender systems improve context-free recommenders by exploiting the knowledge of the contextual situation under which a user experienced and rated an item. They use data sets of contextually-tagged ratings ...
  • The DL-Lite Family and Relations 

    Artale, A; Calvanese, D; Kontchakov, R; Zakharyaschev, M (Association for the Advancement of Artificial Intelligence / AI Access Foundation, 2009)
    The recently introduced series of description logics under the common moniker `DL-Lite' has attracted attention of the description logic and semantic web communities due to the low computational complexity of inference, ...
  • Do feelings matter? On the correlation of affects and the self-assessed productivity in software engineering 

    Graziotin D; Wang X; Abrahamsson P (2014)
    Background: software engineering research (SE) lacks theory and methodologies for addressing human aspects in software development. Development tasks are undertaken through cognitive processing activities. Affects (emotions, ...
  • Documenting Design-Pattern Instances: A Family of Experiments on Source-Code Comprehensibility 

    Scanniello, G; Gravino, C; Risi, M; Tortora, G; Dodero, G (Association for Computing Machinery (ACM), 2015)
    Design patterns are recognized as a means to improve software maintenance by furnishing an explicit specification of class and object interactions and their underlying intent [Gamma et al. 1995]. Only a few empirical ...
  • A Domain-specific Rule Generation Using Model-Driven Architecture in Controlled Variability Model 

    Mani N; Helfert M; Pahl C (2017)
    The business environment changes rapidly and needs to adapt to the enterprise business systems must be considered for new types of requirements to accept changes in the business strategies and processes. This raises new ...
  • Dynamic sub-GOP forward error correction code for real-time video applications 

    Xiao J; Tillo T; Lin C; Zhao Y (2012)
    Reed-Solomon erasure codes are commonly studied as a method to protect the video streams when transmitted over unreliable networks. As a block-based error correcting code, on one hand, enlarging the block size can enhance ...
  • E-connections of abstract description systems 

    Kutz, O; Lutz, C; Wolter, F; Zakharyaschev, M (Elsevier, 2004)
    Combining knowledge representation and reasoning formalisms is an important and challenging task. It is important because non-trivial AI applications often comprise different aspects of the world, thus requiring suitable ...
  • Editorial 

    Ricci F (2014)
    Dear colleagues and readers, It is with great pleasure that I welcome you to the first issue of the Journal of Information Technology and Tourism that is now published by Springer. In the last issue, which was published ...
  • Effects of asymmetric vertical disruptions on ITER components 

    Albanese R; Carpentieri B; Cavinato M; Minucci S; Palmaccio R; Portone A; Rubinacci G; Testoni P; Ventre S; Villone F (2015)
    This paper deals with the halo current distribution due to asymmetric vertical displacement events (VDEs) and the subsequent force distributions on the conducting structures in the ITER tokamak. Both the eddy and halo ...
  • An efficient elimination strategy for solving PageRank problems 

    Shen ZL; Huang TZ; Carpentieri B; Gu XM; Wen C (2017)
    In Web link structures, similar link distributions often occur, especially for pages from same hosts. For PageRank problems, similar in-link distributions of pages result in similar row patterns of the transition matrix. ...
  • Efficient haplotype block recognition of very long and dense genetic sequences 

    Taliun, D; Gamper, J; Pattaro, C (2014)
    Conclusions: The MIG(++) enables to perform LD-based haplotype block recognition on genetic sequences of any length and density. In the new generation sequencing era, this can help identify haplotypes that carry rare ...
