Hackathons for biophysics education: simulating the cytoskeleton
No full textHackathons are intensive innovation-oriented events where participants work in teams to solve problems or create projects in as little as 24 or 48 hours. These events are common in startup culture, open source communities and mainstream industry. Here we examine how hackathons can be ported to academic
teaching, specifically in computational biophysics. We propose hackathons as a teaching modality distinct from traditional courses and structured workshops. In particular, we suggest they can offer a low-stakes platform for students to overcome entry barriers to computational tools or to explore new topics, disciplines, and skills beyond their academic comfort zone. We tested thisformat in two computational biophysics hackathons on the G\"ottingen campus in 2023 and 2024, providing practical insights and a preliminary evaluation. To
the best of our knowledge, the 2024 event is the first public hackathon dedicated to Biophysics. This paper explores the benefits of the hackathon format for teachers and researchers and provides guidelines for running a hackathon adapted to a teaching goal
Intentions And Information In Discourse
No full textThis paper is about the flow of inference between communicative intentions, discourse structure and the domain during discourse processing. We augment a theory of discourse interpretation with a theory of distinct mental attitudes and reasoning about them, in order to provide an account of how the attitudes interact with reasoning about discourse structure. INTRODUCTION The flow of inference between communicative intentions and domain information is often essential to discourse processing. It is well reflected in this discourse from Moore and Pollack (1992): (1)a. George Bush supports big business. b. He's sure to veto House Bill 1711. There are at least three different interpretations. Consider Context 1: in this context the interpreter I believes that the author A wants to convince him that (1b) is true. For example, the context is one in which I has already uttered Bush won't veto any more bills. I reasons that A's linguistic behavior was intentional, and therefore that A believ..
Visualization of the Dirichlet-Voronoi cells in S<sup>2</sup>×R space
No full textThe S2×R geometry can be derived by the direct product of the spherical plane S2 and the real line R. In [1] J. Z. Farkas has classified and given the complete list its space groups. In [6] the second author has studied the geodesic balls and their volumes in S2×R space, moreover he has introduced the notion of geodesic ball packing and its density and have determined the densest geodesic ball packing for generalized Coxeter space groups of S2×R.The aim of this paper to develop a method to study and visualize the Dirichlet-Voronoi cells belonging to a given ball packing. We apply our former results on the equidistant surfaces of the S2×R geometry (see [5]) to determine the D-V cells to locally optimal ball packings belonging to S2×R space groups generated by glide reflections.E. Molnár has shown in [3], that the homogeneous 3-spaces have a unified interpretation in the real projective 3-sphere, in our work we will use this projective model of S2×R geometry. We will use the Wolfram Mathematica software for visualization of the arrangement of a locally optimal geodesic ball packing and its Dirichlet-Voronoi cell of a given glide reflection space group

Published: May-June 2009
Category: » University-showcase » Awards
The DE Oracle @ UMUC was recently named a finalist in the 2009 Learning Impact awards program
sponsored by the IMS Global Learning Consortium (http://www.imsglobal.org/) . The program recognizes
exceptional applications and implementations of technology that support learning and address global
challenges in education. The DE Oracle was nominated under the categories of repository (product) and
faculty support (service).
Kathleen Puckett Ford, director of the Center for Support of Instruction, will showcase the DE Oracle at
IMS's Learning Impact 2009 conference (http://www.imsproject.org/learningimpact2009/agenda.html) , to be
held in Barcelona in mid-May. Kathleen will demonstrate the DE Oracle and its impact on the UMUC
community to a panel of global experts who will determine the final rankings of all the worldwide
finalists. The full list of finalists is available at http://www.imsglobal.org/learningimpact2009

Adaptive Incremental Nonlinear Dynamic Inversion for Consistent Pitch Rate Control
No full textControl augmentation systems based on Incremental Nonlinear Dynamic Inversion (INDI) are able to provide high-performance nonlinear control without the need for a model of the complete system. Considering a pitch rate control law for a fixed-wing aircraft, only a model for the elevator control effectiveness (CE) and sensor feedback of the pitch acceleration are required for the model inversion. Despite the increased robustness against model error due to the decreased model dependency, control laws based on INDI could still show performance variation when the on-board CE model deviates from the actual CE. This thesis will put this in the context of the control performance of high-performance aircraft. Furthermore, multiple adaptive INDI control techniques are investigated as possible solutions. This study revealed that adaptive control based on Least-Mean-Square (LMS) parameter estimation has the most potential. A second analysis using handling quality and stability (HQ&S) requirements showed that this approach is able to decrease variation in the HQ&S as well. However, the results also show that HQ&S variation for large centre of gravity shifts could not always be fully mitigated by adaptive control as it is possible that the time-scale separation assumption becomes impaired.Aerospace Engineerin
