Threatening test scenarios and their effect on emotions and motivation of women in math. Präsentation bei der 14. Fachgruppentagung Sozialpsychologie (FGSP) der Deutschen Gesellschaft für Psychologie (DGPs) in Bielefeld (Germany). To think or not to think – suppression and reappraisal of task-irrelevant thoughts under stereotype threat. Präsentation bei der Transfer of Knowledge Conference des ...

This article mainly studies automatic navigation control methods for agricultural machinery. The navigation system takes RTK-DGPS and inertial measurement unit as positioning sensors. The preview control mode was researched for curve path tracking. The preview control model is to determine the aiming point and calculate the lateral deviation. Automatic turning was realized by fuzzy control meth...

In 2002, the maturity of grapevine was researched on the basis of sugar content, total titratable acidity and pH at seven locations with an undulating topography in four varieties 'Chardonnay', 'Riesling', 'Welschriesling' and 'Sauvignon'. All sampling points were geo-referenced simultaneously with DGPS for creating sugar maps. The significant relationship between the varying altitude above sea...

A novel method of map matching using the Global Positioning System (GPS) has been developed for civilian use, which uses digital mapping data to infer the <100 metres systematic position errors which result largely from “selective availability” (S/A) imposed by the U.S. military. The system tracks a vehicle on all possible roads (road centre-lines) in a computed error region, then uses a method...

This paper investigates the usefulness of information criteria for inference on the number of structural breaks in a standard linear regression model. In particular, we propose a modified penalty function for such criteria based on theoretical arguments, which implies each break is equivalent to estimation of three individual regression coefficients. A Monte Carlo analysis compares information ...

To localize a vehicle on a map, a reliable road selection system is essential. For this purpose, the article presents a credibilist multi-criteria association algorithm that performs data association between the infrastructure information (the map) and the noisy measurements of two sensors (DGPS, Odometer). The algorithm takes into account the inaccuracy, the uncertainty and the redundancy of t...

This paper presents the conceptual and technical aspects of a system in development that precisely determines athlete’s trajectory through a course. Carrier phase-based (CP-DGPS) positioning represents core of the system, while tri-axial accelerometer and magnetic sensors act as an autonomous aid that offers instantaneous attitude determination and can potentially help when navigating through G...

When a weighted graph is an instance of the Distance Geometry Problem (DGP), certain types of vertex orders (called discretization orders) allow the use of a very efficient, precise and robust discrete search algorithm (called Branch-and-Prune). Accordingly, finding such orders is critically important in order to solve DGPs in practice. We discuss three types of discretization orders, the compl...

Machine learning (ML) methods often require large volumes of labeled data to achieve meaningful performance. The expertise necessary for labeling in medical applications like pathology presents a significant challenge developing clinical-grade tools. Crowdsourcing approaches address this by collecting labels from multiple annotators with varying degrees expertise. In recent years, have been ada...
