This is because of the elastic energy: A square oriented with sides perpendicular to the 〈10〉 directions has a lower elastic energy than a circle for given material parameters. However, the interfacial energy term diverges at a sharp corner, so an intermediate shape that is square-like but ...
If you're using the same projection over and over, the following is a simple way to create the .prj file assuming your base filename is stored in a variable called "filename": with open("{}.prj".format(filename), "w") as prj: wkt = 'GEOGCS["WGS 84",' wkt += 'DATUM["WGS...
This metric has the important property that it is invariant with respect to translation, rotation and change of scale. The metric employs a pie-wedge sector, whose origin is the center of the shape and whose sides intersect with the shape at two points along its circumference. The two points...
The newest version of PyShp, version 2.0 introduced some major new improvements. A great thanks to all who have contributed code and raised issues, and for everyone's patience and understanding during the transition period. Some of the new changes are incompatible with previous versions. Users of...
There are different types of hexagons, each with a definite set of properties. Some hexagons may have equal sides, whereas some may have their vertices pointing inwards. So, let us sum up the basicproperties of hexagonsin general. A hexagon (“hex”: six and “gonia”: corners) has 6 ...
f Two-step peeling with orthogonal peeling directions results in hyperboloids. Left: top view (top) and side view (bottom) schematics of the two-step peeling process. Parallel red and blue lines indicate the adhesion regions on different sides of the plastic film. The line direction indicates ...
Blebs forming with a complete envelope, also called lobulations, including the two membranes and the lamina have also been observed. In this case, the mechanism of formation could either be a separation of the two types of lamins: lamin A/C and lamin B (a phenomenon which could be similar...
When balancing is used null shapes are created on the geometry side or records with a value of "NULL" for each field is created on the attribute side. This gives you flexibility in how you build the shapefile. You can create all of the shapes and then create all of the records or ...

2.21 top). The beam has a Young's modulus of 100 GPa, a cross-sectional width of 0.05 m, and height of 0.1 m, which result in a cross-sectional moment of inertia of 512×10−5m4. In theory, a beam should be modeled with beam elements to secure the best result. However, in ...
