This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

This document discusses the various approaches to representing space that have been taken in ontology and qualitative spatial representation and reasoning. The parameters concerning the ontological modelling of space, both in a general sense and concerning the SFB specifically, are given. The specific projects discussed include: SUMO-space, OpenCyc-space, DOLCE-space, BFO-space, and Geographic ...

The Transregional Collaborative Research Center SFB/TR 8 Spatial Cognition was established by the German Science Foundation (DFG) at the Universities of Bremen and Freiburg in January 2003. 13 Research projects pursue interdisciplinary research on intelligent spatial information processing. This article introduces the research field of spatial cognition and reports on aspects from cognitive psy...

Cognitive science at Freiburg has a long-standing tradition of cooperating with computer science in basic and applied research. In this project report we present current research in spatial cognition as part of the SFB/TR8 Spatial Cognition (Bremen and Freiburg) in our lab in Freiburg. Our research interests cover the analysis of wayfinding strategies, external and internal spatial representati...

Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...

Segmented filamentous bacteria (SFB) are host-specific intestinal symbionts that comprise a distinct clade within the Clostridiaceae, designated Candidatus Arthromitus. SFB display a unique life cycle within the host, involving differentiation into multiple cell types. The latter include filaments that attach intimately to intestinal epithelial cells, and from which "holdfasts" and spores devel...

SFB, a candidate gene for the pollen S gene, has been identified in several species of Prunus (Rosaceae). We isolated 5 new SFB alleles from 6 Japanese apricot (Prunus mume) lines using a specific Prunus SFB primer pair (SFB-C1F and Pm-Vb), which was designed from conserved regions of Prunus SFB. The nucleotide sequences of these SFB genes were submitted to the GenBank database. The 5 new SFB a...

Objectives Segmented filamentous bacteria (SFB) have been detected in a wide range of different animal. Recently, the presence of SFB-like bacteria was shown in biopsies of the terminal ileum and ileocecal valve of both patients with ulcerative colitis and control subjects. The aim of this study was to verify whether PCR methods could be used for the detection of SFB in biopsy of patients with ...

The SFB/TR 8 pursues interdisciplinary research in Spatial Cognition. In twenty projects, computer scientists, psychologists, and linguists collaborate in basic research as well as in application-oriented development. We present a selection of projects to illustrate the variety of research issues addressed within this research center.
