Voronoi space division of a polymer: Topological effects, free volume, and surface end segregation

Voronoi space division of a polymer: topological effects, free volume, and surface end segregation.

In order to investigate the topological effects of chain molecules, united-atom molecular dynamics simulations of a 500-mer polyethylene linked by 50 hexyl groups (a grafted polymer having 52 ends) are carried out and analyzed in terms of Voronoi space division. We find that the volume of a Voronoi polyhedron for a chain end is larger than that for an internal or junction atom, and that it is t...

Menger probabilistic normed space is a category topological vector space

In this paper, we formalize the Menger probabilistic normed space as a category in which its objects are the Menger probabilistic normed spaces and its morphisms are fuzzy continuous operators. Then, we show that the category of probabilistic normed spaces is isomorphicly a subcategory of the category of topological vector spaces. So, we can easily apply the results of topological vector spaces...

A Free Space Optical Crossbar Switch Using Wavelength Division Multiplexing and Vertical-Cavity Surface-Emitting Lasers

Building large crossbar switches for low-latency, highbandwidth interprocessor interconnects in multiprocessor systems is a difficult task because of the many practical limitations of digital electronics. This paper presents a first order design for a crossbar switch which utilizes wavelength tunable vertical-cavity surface-emitting laser (VCSEL) technology and free space optics. Free space opt...

Reflection From Free Surface of a Rotating Generalized Thermo-Piezoelectric Solid Half Space

The analysis of rotational effect on the characteristics of plane waves propagating in a half space of generalized thermo-piezoelectric medium is presented in context of linear theory of thermo-piezoelectricity including Coriolis and centrifugal forces. The governing equations for a rotating generalized thermo-piezoelectric medium are formulated and solved for plane wave solutions to show the p...
