Sex differences in navigation in a tabletop octagon navigation task
… tabletop versions of the MWT, called the Octagon Navigation Task to study the use of these spatial frameworks. Men outperformed women in the allocentric condition. Women outperformed men in the egocentric condition. No sex differences were found in the neutral condition, which allowed the …

The polygonal chapter house: architecture and society in Gothic Britain
… house of Westminster Abbey from 1246-55 that octagon chapter houses mostly with large traceried windows appear at least fourteen times at widely dispersed sites throughout England and Scotland. Writers have speculated about or interpreted the origins and meaning of that planning innovation …

Transversals to horocycle flow on the moduli space of translation surfaces
… compute the distribution in the case of the octagon, the first case where the Veech group has multiple cusps, how to generalize the construction of the transversal to the general Veech case (both joint work with Caglar Uyanik), and how to parametrize the transversal in the case of a generic …

Entwicklung und Bau eines auf Proportionalkammern basierenden Übergangsstrahlungsdetektors für das AMS-02-Weltraumexperiment
… The housing consists of a conically shaped octagon structure made out of CFC-Al-honeycomb material and is closed by a lower and upper honeycomb plate. In this thesis special emphasis will be focused on the straw module production and space qualification aspects like structural verification, …

Visualizing Geometric Structures on Topological Surfaces
… 2 surface is more complicated. We prove that an octagon representing a genus 2 surface can have its edges identified in different combinations to produce exactly four different possible presentations of fundamental groups. We explore surgeries on one of those types and show that surgeries that …

Grid Domains for Analysing Software
… cally the boxes, bounded difference shapes and octagon domains. The “weakly tight product” is introduced, an operation that ensures each constraint of the polyhedral representation intersects a point of the grid, and the “tight product”, which ensures each constraint of the polyhedral rep- …

Electrical and thermal transport in 2D materials: role of environment and imperfections
… of this value. We find that LDs with carbon atom octagon defects have lower thermal transmission than GBs with pentagon and heptagon defects. We apply our findings to study the thermal conductivity of polycrystalline graphene for practical applications, and find that the type and size of GBs play …

Understanding The Meanings of Built Environment Within Urban Educational Environments: A Critical Analysis of the Qatar University Campus
This dissertation focuses on examining the significance of the Qatar University campus as designed by its architect Kamal El Kafrawi. The study takes on a multi-perspective view. The underlying and unifying approach is based on Amos Rapoport's concept of the meaning of the built environment. …

Space qualification of the transition radiation detector of the AMS-02 experiment and indirect search for dark matter
… with fleece radiators supported in a conical octagon structure. Major design constraints arise from operating it in a space environment with limited power resources.The TRD readout system is divided into 82 front-end electronic circuits and two pairs of crate electronics and power distribution …
