    The AppleTV-Cluster: Towards Energy Efficient Parallel Computing on Consumer Electronic Devices

    In the last two decades supercomputers have sustained a remarkable growth in performance that even out-performed the predictions of Moore's law, primarily due to increased levels of parallelism. As industry and academia try to come up with viable approaches for exascale systems, attention turns to energy efficiency as the primary...

    External Technology Supply and Client-Side Innovation

    The market for IT outsourcing has extensively grown during the last decade. At the same time the aim of external IT provision has transformed from cost-cutting to following strategic goals. For related types of business services, the literature has identified a potential to build bridges for innovation. The authors employ...

    Comprehensive Performance Monitoring for GPU Cluster Systems

    Accelerating applications with GPUs has recently garnered a lot of interest from the scientific computing community. While tools for optimizing individual kernels are readily available, there is a lack of support for the specific needs of the HPC area. Most importantly, integration with existing parallel programming models (MPI and threading)...

    MiniAgda: Integrating Sized and Dependent Types

    Sized types are a modular and theoretically well-understood tool for checking termination of recursive and productivity of corecursive definitions. The essential idea is to track structural descent and guardedness in the type system to make termination checking robust and suitable for strong abstractions like higher-order functions and polymorphism. To study...

    Backward Compatibility To Sustain Market Dominance - Evidence From The US Handheld Video Game Industry

    The introduction of a new product generation forces incumbents in network industries to rebuild their installed base to maintain an advantage over potential entrants. The authors study if backward compatibility can help moderate this process of rebuilding an installed base. Using a structural model of the US market for handheld...

    Improving the Accessibility of NFC/RFID-Based Mobile Interaction Through Learnability and Guidance

    NFC and RFID technologies have found their way into current mobile phones and research has presented a variety of applications using NFC/RFID tags for interaction between physical objects and mobile devices. Since this type of interaction is widely novel for most users, there is a considerable initial inhibition threshold for...

    CHANGEREFINERY: Assisted Refinement of High-Level IT Change Requests

    The IT Infrastructure Library (ITIL) is a set of best practices that are widely accepted for IT service management. Change management is a core ITIL process that oversees the handling of IT changes and ensures that all change requests are carefully prioritized and authorized, that business and technical impacts are...

    ProUD: Probabilistic Ranking in Uncertain Databases

    There are a lot of application domains, e.g. sensor databases, traffic management or recognition systems, where objects have to be compared based on vague and uncertain data. Feature databases with uncertain data require special methods for effective similarity search. In this paper, the authors propose an effective and efficient probabilistic...

    Probabilistic Similarity Search for Uncertain Time Series

    A probabilistic similarity query over uncertain data assigns to each uncertain database object o a probability indicating the likelihood that o meets the query predicate. In this paper, the authors formalize the notion of uncertain time series and introduce two novel and important types of probabilistic range queries over uncertain...

    Host Virtualization: A Taxonomy of Management Challenges

    Host virtualization is quickly being introduced to production environments as it facilitates the recent years' computing centre consolidation efforts. While its introduction offers new opportunities in IT management, it also presents challenges that are yet to be tackled. In this paper, the authors chart these areas of concern according to...

    Software Engineering for Ensembles

    Software development is difficult, even if authors control most of the operational parameters and if the software is designed to run on a single machine. But in the future authors will face an even more challenging task: engineering ensembles consisting of thousands, or even millions, of nodes, all operating in...

    Combination Notes: Market Segmentation And Equity Transfer

    This paper empirically analyzes a particular type of notes observed in securitization transactions: combination notes. Combination notes are formed by combining parts of two or more tranches of securitization transactions, where one part usually consists of a share of the first loss piece. It is analyzed whether combination notes are...
