Automatic building detection from aerial images for mobile robot mapping

To improve mobile robot outdoor mapping, information about the shape and location of buildings is of interest. This paper describes a system for automatic detection of buildings in aerial images taken from a nadir view. The system builds two types of independent hypotheses based on the image contents. A segmentation process implemented as an ensemble of SOMs (Self Organizing Maps) is trained and used to create a segmented image showing different types of roofs, vegetation and sea. A second type of hypotheses is based on an edge image produced from the aerial photo. A line extraction process uses the edge image as input and extracts lines from it. From these edges, corners and rectangles that represent buildings are constructed. A classification process uses the information from both hypotheses to determine whether the rectangles are buildings, unsure buildings or unknown objects

Sharing Polarization within Quantum Subspaces

Given an ensemble of n spins, at least some of which are partially polarized, we investigate the sharing of this polarization within a subspace of k spins. We assume that the sharing results in a pseudopure state, characterized by a single purity parameter which we call the bias. As a concrete example we consider ensembles of spin-1/2 nuclei in liquid-state nuclear magnetic resonance (NMR) systems. The shared bias levels are compared with some current entanglement bounds to determine whether the reduced subspaces can give rise to entangled states.Comment: 7 pages, 3 figure

Universities Confront ‘Tech Disruption’: Perceptions of Student Engagement Online Using Two Learning Management Systems

This article is a teaching note on the experiences of students and professors as they adapted to the use of a new learning management system (LMS). Using pedagogical theories of student engagement and the online learning process, we explore how the design of an LMS affects student satisfaction and interaction with peers and the instructor. This descriptive, qualitative study reports student and instructor experiences in four hybrid sociology courses that used Google Classroom as an experimental LMS. These same students also used Blackboard, a more traditional LMS, in their other sociology classes, establishing a quasi within-subject point of comparison for these two systems. A survey (n=72) and four focus groups (n=54) were conducted among students to determine how student engagement is experienced differently on Classroom and Blackboard. Eighty-three percent of students reported feeling satisfied with Classroom over Blackboard. Focus groups revealed themes relating to usability and learnability; interaction and individuality; and facilitation of learning. Students and instructors responded more positively, with some exceptions, to Classroom’s reliability and interface, but claims about the transformative power of online tools are not wholly supported by student or instructor experiences. The study advances our understanding of how the LMS interface, design, and functionality play a role in student engagement online. Further research is needed to understand the full extent of Classroom’s impact on learning in the higher education landscape
