Path Planning is one of the most computationally intensive tasks in robot systems and a challenge in dynamically changing environments. By means of FPGAs it is possible to process time-critical and data-intensive tasks in robot systems efficiently. We have developed a parallel path planning algorithm which is based on Marching Pixels, an organic computing principle. The algorithm is optimized for FPGA-based processing. A parallel implementation approach together with an efficient buffering of the map data allowed us to obtain a processing rate suitable for real time applications, even for higher resolutions. We achieved a processing rate of 80 maps per second for VGA resolution (640 × 480) on a midsize Virtex-5 FPGA.

Patarin proposed the dragon scheme, pointed out the insecurity of the dragon algorithm with one hidden monomial and suggested a candidate dragon signature algorithm with a complicated function. This paper presents an algebraic method to attack the candidate dragon signature algorithm. The attack borrows the basic idea of the attack due to Kipnis and Shamir, and utilizes the underlying algebraic structure of the candidate dragon signature algorithm over the extension field to derive a way to enable the variable Y be viewed as a fixed value. The attack recovers the private keys efficiently when the parameters are n≤2s and D=[logq^d]≤3.
Graph theory has attracted great attention for the problem of image segmentation in recent years. In this paper we deduce the unified form of the normalized cut (Ncut) algorithm and the Isoperimetric algorithm, and th...

Despite being a set of proven, well-documented, contextualized recommendations for solving frequently occurring user interface design problems, user interface design patterns are still not widely used. We believe this is due to the lack of tools to help designers find patterns and identify how they can be combined to solve user interface design problems. This paper proposes a flexible model to represent UIDPs and their relationships. The flexibility of our model, based on RDF Statements, is to provide a structure to the representation of the UIDPs in order to allow the development of tools to automate their use.

Gathering product specifications from the Web is labor-intensive and still requires much manual work to retrieve and integrate the information in enterprise information systems or online shops. This work aims at significantly easing this task by introducing algorithms for automatically retrieving and extracting product information from producers' websites while only being supplied with the product's and the producer's name. Compared to previous work in the field, it is the first approach to automate the whole process of locating the product page and extracting the specifications while supporting different page templates per producer. An evaluation within a federated consumer information system proves the suitability of the developed algorithms. They may easily be applied to comparable product information systems as well to minimize the effort of finding up-to-date product specifications.

Online social lending is the Web 2.0's response to classical bank loans. Borrowers publish credit applications on websites which match them with private investors. We point to a conflict between economic interests and privacy goals in online social lending, empirically analyze the effect of data disclosure on credit conditions, and outline directions towards efficient yet privacy-friendly alternative credit markets.
