  text: Today, mobile and embedded real-time systems have to cope with the migration
    and allocation of multiple software tasks running on top of a real-time operating
    system (RTOS) residing on one or multiple system processors. Abstract RTOS simulations
    and timing analysis applies for fast and early estimation to configure it towards
    the individual needs of the application and environment. In this context, a high
    accuracy of the simulation compared to an instruction set simulation (ISS) is
    of key importance. In this paper, we investigate the accuracy of abstract RTOS
    simulation and compare it to ISS and the behavior of the physical system. We show
    that we can reach an increased accuracy of the simulation when we inject noise
    into the time model. Our results indicate that it is sufficient to inject uniformly
    distributed random time values to the RTOS real-time clock.

  text: Currently, middleware for smart home networks with embedded and mobile devices
    are in the focus of several investigations. In this paper, we propose a middleware
    for secure management of device and user profiles by integrating a profile database
    with a generic authentication scheme for an X.509 enabled ticket management in
    the context of the OSGi framework. After the introduction of the individual system
    components and their interaction, we also discuss potential system attacks.

  text: In contrast to processors, current reconfigurable devices totally lack programming
    models that would allow for device independent compilation and forward compatibility.
    The key to overcome this limitation is hardware virtualization. In this paper,
    we resort to a macro-pipelined execution model to achieve hardware virtualization
    for data streaming applications. As a hardware implementation we present a hybrid
    multi-context architecture that attaches a coarse-grained reconfigurable array
    to a host CPU. A co-simulation framework enables cycle-accurate simulation of
    the complete architecture. As a case study we map an FIR filter to our virtualized
    hardware model and evaluate different designs. We discuss the impact of the number
    of contexts and the feature of context state on the speedup and the CPU load.

  text: '3D-graphics are becoming popular in a steadily increasing number of areas
    such as entertainment, scientific visualization, simulation, and virtual reality.
    Despite this rapid growth the generation of animated 3D scenes is by no means
    trivial. Since animated 3D objects evolve over time the authors denote these objects
    as 4D. The article presents a novel approach to the rapid prototyping of 4D models.
    They introduce the AAL (Animated Agent Layer) system. AAL is an interpreter-based
    approach covering a textual (AAL-PR) as well as a visual command language (AAL-VL)
    for the specification of the dynamics in 4D scenes. AAL provides support for different
    levels of abstraction: primitives, structured objects, animated objects, and animated
    (autonomous) agents.'

  text: This article discusses the application of Pictorial Janus (PJ) for the rapid
    development and analysis of protocols by animation and complete visualization.
    In order to make PJ applicable in the context of hardware description we first
    extend PJ by timing facilities (Timed PJ) and introduce an approach for integrating
    VHDL models into this visual framework preserving the simulation semantics of
    VHDL. We finally give the example of the specification and animation of a non
    interlocked protocol.
