Any simulation-based evaluation of an interconnection network proposal requires a good characterization of the workload. Synthetic traffic patterns based on independent traffic sources are commonly used to measure performance in terms of average latency and peak throughput. As they do not capture the level of self-throttling that occurs in most parallel applications, they can produce inaccurate throughput estimates at high loads. Thus, workloads that resemble the varying levels of synchronization of actual applications are needed to study the performance of interconnection networks. One approach is to use simple, burst-synchronized synthetic workloads that emulate the self-throttling of many parallel applications. To validate this approach, we compare the gains achieved by a restrictive injection mechanism under this workload with those obtained using traces from the NAS Parallel Benchmarks. This study confirms that the burst-synchronized traffic model provides reasonable performance estimates, which could be improved by taking into account dependency chains between messages.

In this paper, we present a large-scale interactive book browsing installation for children's libraries called StorySurfer. The StorySurfer prototype is developed within the Interactive Children's Library project, which includes interests from within design, research, industry, and libraries. The objective of the project is to give room for and encourage the physical activities of children, while pursuing to connect these with the basic digital and analogue services of the library e.g. borrowing and handing in books, searching for information, and providing access to a rich variety of media.

Public spaces are changing from being ungoverned places for interaction to be more formalized, controlled, less interactive, and designed places aimed at fulfilling a purpose. Simultaneously, new personal mobile technology aims at providing private individual spaces in the public domain. In this paper we explore the implications of interacting in public space and how technology can be rethought to not only act as personal devices, but be the tool to reclaim the right and possibility to interact in public spaces. We introduce information exchange, social support and regulation as three central aspects for reclaiming public space. The PhotoSwapper application is presented as an example of a system designed to integrate pervasive technology in a public setting. The system is strongly inspired by the activities at a traditional market place. Based on the design of the application we discuss four design challenges when designing for public interaction.

We describe an algorithm for navigation state estimation during planetary descent to enable precision landing. The algorithm automatically produces 2D-to-3D correspondences between descent images and a surface map and 2D-to-2D correspondences through a sequence of descent images. These correspondences are combined with inertial measurements in an extended Kalman filter that estimates lander position, velocity and attitude as well as the time varying biases of the inertial measurements. The filter tightly couples inertial and camera measurements in a resource-adaptive and hence real-time capable fashion. Results from a sounding rocket test, covering the dynamic profile of typical planetary landing scenarios, show estimation errors of magnitude 0.16 m/s in velocity and 6.4 m in position at touchdown. These results vastly improve current state of the art and meet the requirements of future planetary exploration missions.
