Der Globefish sowie die Globemouse sind zwei an der BauhausUniversität Weimar entwickelte Eingabegeräte, welche jeweils sechs Freiheitsgrade (degree of freedom, DOF) besitzen. Das heißt, man kann damit die Rotation eines Objekts sowie seine Verschiebung im dreidimensionalen Raum steuern. Im Folgenden sollen nun die in [2] vorgestellten Geräte und Versuchsergebnisse zusammenfassend betrachtet we...

Time-synchronised flow velocity, temperature, and heat flux measurements were preformed to characterise the interaction of a single rising ellipsoidal bubble with the free convection flow from a heated vertical flat surface. The heat transfer measurements from the surface were provided by a hot film heat flux sensor calibrated using a pre-calibrated microfoil heat flux sensor. Two thermocouples...

Vortex formation and force generation of clapping plates with various aspect ratios (AR) and stroke angles were investigated. Experiments were performed with a pair of hinged rectangular plates that were rotated symmetrically in a static fluid, and defocusing digital particle image velocimetry was employed to measure the threedimensional flow field. Single-plate cases were also studied to compa...

Vortex structures made by impulsively translating low aspect-ratio plates are studied experimentally using defocusing digital particle image velocimetry. The investigation of translating plates with a 90◦ angle of attack is important since it is a fundamental model for a better understanding of drag-based propulsion systems. Rectangular flatrigid, flexible and curved-rigid thin plates with the ...

Business-Intelligence-Systeme stellen durch ihre Unterstützung bei der Entscheidungsfindung für Unternehmen eine wichtige Rolle dar. Mit einer stetig dynamischeren Unternehmensumwelt geht daher die Anforderung nach der agilen Entwicklung dieser Systeme einher, so dass in der BI-Domäne zunehmend erfolgreich agile Methoden und Vorgehensmodelle eingesetzt werden. Die Weiterentwicklung und Anpassun...

The authors are preparing for cross-cultural studies of immunosuppressive behaviors and emotions, commonly called "Type C," in both healthy persons and in patients with cancer. To this end, validity and reliability of a Type C Personality Inventory were assessed in a sample of 128 healthy volunteers. Reliability of the instrument was supported by moderate to high Cronbach alpha coefficients. Ac...

The aim of this study is to develop a valid and reliable measurement tool that measures mathematical visualization perceptions for mathematics teacher candidates. Therefore, the type survey research. Research was carried out with 462 (336 Female, 125 Male) candidates from university located in Eastern Anatolia region Turkey 2018-2019 spring season. Exploratory confirmatory factor analyzes were ...
