Tests and Requirements, Requirements and Tests: A Möbius Strip

Robert C. Martin, Grigori Melnik
2008 IEEE Software  
Weinberg W hen Donald Gause and Gerald Weinberg wrote this statement, 1 they were asserting that writing tests is an effective way to test requirements' completeness and accuracy.  ...  They also suggest writing these tests when gathering, analyzing, and verifying requirements-long before those requirements are coded.  ...  We believe that concrete requirements blend with acceptance tests in much the same way as the two sides of a strip of paper become one side in a Möbius strip (see figure 1 ).  ...

A decoder for the triangular color code by matching on a Möbius strip [article]

Kaavya Sahay, Benjamin J. Brown
2021 arXiv   pre-print
Here we propose a decoder for the planar color code with a triangular boundary where we match syndrome defects on a nontrivial manifold that has the topology of a Möbius strip.  ...  Furthermore, by exhaustively testing over five billion error configurations, we find that a modification of our decoder that manually compares inequivalent recovery operators can correct all errors of  ...  Indeed, this expression would require modification to deal with edges that pass over creases on the Möbius strip.  ...

The Shape of a Möbius Strip via Elastic Rod Theory Revisited [article]

Alexander Moore, Timothy J. Healey
2016 arXiv   pre-print
More recently in 2007, Starostin and van der Heijden pointed out that an actual M\"obius band "localizes" into a nearly flat triangular configuration as the ratio of the strip width to center-line circumference  ...  Starting from the solution for a square cross-section (isotropic), they employ numerical continuation in the cross-sectional aspect ratio in order to approach the solution for a thin strip.  ...  Acknowledgements This work was supported in part by the National Science Foundation through grants DMS-1007830 and DMS-1312377, which is gratefully acknowledged.  ...

GOLDEN MOBIUS STRIP: LESSING'S "THE GOLDEN NOTEBOOK" AS A FRAGMENTED NARRATIVE

Baysar TANIYAN
2009 Ankara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Dergisi  
Abstract The post-war period literature, or postmodern literature, is generally described with the adjectives duplication, contradiction, chaos, and fragmentation.  ...  However, fragmentation is the key concept among them as the term is employed in a wide range of fields. Witnessing the failure of humanist ideal of wholeness, * Arş. Gör.  ...  Thus, the narration turns back where it started like a mobius strip, a situation which Molly Hite also agrees (Hite, 1988: 22) .  ...

Buckling of Naturally Curved Elastic Strips: The Ribbon Model Makes a Difference [chapter]

Basile Audoly, Keith A. Seffen
2016 The Mechanics of Ribbons and Möbius Bands  
Conversely, a multi-covered, overcurved metallic strip can unfold dynamically into a circular configuration having a lower covering index.  ...  In experiments, we first show that a loop formed using a metallic strip can become unstable if its radius is smaller than its natural radius of curvature (undercurved case): the loop then folds onto itself  ...  Section 2 details our construction and testing of a multistable hoop from a bandsaw blade.  ...

Spin frustration effects in an odd-member antiferromagnetic ring and the magnetic Möbius strip

Olivier Cador, Dante Gatteschi, Roberta Sessoli, Anne-Laure Barra, Grigore A. Timco, Richard E.P. Winpenny
2005 Journal of Magnetism and Magnetic Materials  
The spin frustrated ring is visualized by a Moebius strip. The ?knot? of the strip represents the region of the ring where the AF interactions are more frustrated.  ...  The ring possesses an even number of unpaired electrons and a S=0 ground state but, due to competing AF interactions, the first excited spin states are close in energy.  ...  Acknowledgments We acknowledge the financial support of the EPSRC (UK), of the EC through the EC-TMR Network and "QuEMolNa" (MRTN-CT-2003-504880) , of the German DFG (SPP 1137), and of INTAS.  ...

Special Coupon Shapes Used in Testing Liner Coatings

It can be said that, in practice, a Mobius shape, like a solid sphere, has only an outside surface, but unlike a sphere, it has a hole for a sling which can be used for support.  ...  Spark testers do not all require a grounding contact through the coating as does the wet sponge unit which in turn must be repaired but cannot be tested. 3.  ...
