In this study, we described the fabrication method for microfluidic channels with circular-cross sectional geometries by reflow phenomenon. The photoresist reflow leads to shape change from rectangular to semicircular, and we optimized the reflow conditions by using positive photoresist to form the perfect cylindrical micropatterns. The resultant circular micropattern was used as a template for...

Given a set P of n points in three dimensions, a cylindrical shell (or zone cylinder) is formed by two circular cylinders with the same axis such that all points of P are between the two cylinders. We prove that the number of cylindrical shells enclosing P passing through combinatorially different subsets of P has size Ω(n) and O(n) (the previously known bound was O(n)). As a consequence, the m...

Hyperelastic materials based on Signorini’s strain energy density are studied by using Shannon wavelets. Cylindrical waves propagating in a nonlinear elastic material from the circular cylindrical cavity along the radius are analyzed in the following by focusing both on the main nonlinear effects and on the method of solution for the corresponding nonlinear differential equation. Cylindrical wa...

10 There is a growing need for tools automating the processing of as-built 3D laser scanned data, and more 11 particularly the comparison of this as-built data with planned works. This paper particularly considers 12 the case of tracking MEP components with circular cross-sections, which essentially include pipes, and 13 some conduits and ducts. Discrepancies between the as-built and as-planned...

In order to make up for the shortcomings of existing theory calculation methods circular diaphragm walls, an alternative method was developed with a clear concept based on cylindrical shell and superposition principle in elasticity named (CCSTCM). We took north anchorage foundation pit G3 Tongling Yangtze River Highway Railway Bridge as example calculated analyzed it by proposed CCSTCM, finite ...

We have investigated the wet thermal oxidation of AlAs in cylindrical geometry, a typical configuration for vertical-cavity surface-emitting lasers. Through both experiment and theoretical calculations, we demonstrate a significantly different time dependence for circular mesas from what has been reported in the literature both in studies of stripes and in a study of circular mesas. We attribut...

In order to solve the limitation of cylindrical geared linkage in trajectory realization, this paper make the non-circular gear pair and double crank hinge five-bar as closed combination, and to probe the feasibility and method of designing non-circular gear based on the given position points in five-bar linkage trajectory region. The discrete rotation angle sequences of non-circular gear pair ...
