This paper presents a creativity support tool, called FreePub, to collect and organize scientific material using mindmaps. Mindmaps are visual, graph-based represenations of concepts, ideas, notes, tasks, etc. They generally take a hierarchical or tree branch format, with ideas branching into their subsections. FreePub supports creativity cycles. A user starts such a cycle by setting up her dom...

We write down all orders large N expansions for the dimensions of irreducible representations of O(N) and Sp(N). We interpret all the terms in these expansions as symmetry factors for singular worldsheet configurations, involving collapsed crosscaps and tubes. We use it to complete the interpretation of two dimensional Yang Mills Theories with these gauge groups, on arbitrary two dimensional ma...

By developing an interactive open source-based WebGIS information portal on war and peace for the online services of the Federal Agency for Civic Education, the Bonn International Center for Conversion (BICC) translates scientific knowledge into easily understandable and subsumable up-to-date information for the general public and young scholars. By aggregating globally scattered data and infor...

Jack D. Cowan Department of Math University of Chicago Chicago, IL 60637 [email protected] We couple the tasks of source separation and density estimation by extracting the local geometrical structure of distributions obtained from mixtures of statistically independent sources. Our modifications of the self-organizing map (SOM) algorithm results in purely digital learning rules which perform...

For a series of multi-source remotely sensed images of the same area, the sensors’ types and the shooting time will be different. Therefore, there will be varying kinds of distortion or noise in the images, especially the features information will be different, resulting incompletely matching in the process of fusion[1]. Most of the existing methods of fusion are unable to achieve a balance bet...

We study the existence of periodic trajectories for nonautonomous differential equations and inclusions remaining in a prescribed compact subset of an extended phase space. These sets of constraints are nonconvex right-continuous tubes not satisfying the viability tangential condition on the whole boundary. We find sufficient conditions for existence of viable periodic trajectories studying pro...

The ATOC Project has aquired trans-Pacific acoustic data from two acoustic sources: one located on Pioneer Seamount off the coast of California, the other located north of Kauai, Hawaii. Transmissions from these sources are detected by U.S. Navy SOSUS arrays located throughout the North Pacific. The time series of acoustic travel times from the Pioneer Seamount and Kauai transmissions are about...

An approach based on the nearest neighbors techniques is presented for producing thematic maps of forest cover (forest/non-forest) and total stand volume for the Terai region in southern Nepal. To create the forest cover map, we used a combination of Landsat TM satellite data and visual interpretation data, i.e., a sample grid of visual interpretation plots for which we obtained the land use cl...

PURPOSE In this report, the authors introduce the general concept of the completeness map, as a means to evaluate the completeness of data acquired by a given CT system design (architecture and scan mode). They illustrate the utility of completeness map by applying the completeness map concept to a number of candidate CT system designs, as part of a study to advance the state-of-the-art in card...
