Ion distributions play a central role in various settings-from biology, where they mediate the electrostatic interactions between charged biomolecules in solution, to energy storage devices, where they influence the charging properties of supercapacitors. These distributions are determined by interactions dictated by the chemical properties of the ions and their environment as well as the long-...

We measured normal and friction forces simultaneously using a recently developed cantilever-based optical interfacial force microscope technique for studies of interfacial structures and mechanical properties of nanoscale materials. We derived how the forces can be incorporated into the detection signal using the classical Euler equation for beams. A lateral modulation with the amplitude of nan...

We investigated by means of polarization microscopy the influence of a magnetic field on the shape and director field of nematic droplets in dispersions of plate-like colloidal particles. To interpret the experimental observations, we put forward a simple theory in which we presume strong anchoring and a sphero-cylindrical droplet shape. This model allows us to extract values for the interfacia...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...

Acoustic cloak using anisotropic density or pentamode (PM) material is capable of concealing target from any detective acoustic wave. The pentamode material scheme is more promising due to its solid phase feature and broadband efficiency [1, 2]. However, perfect PM material in theory doesn’t have static stability, and therefore some imperfection in practically designed microstructure PM materia...

Mining frequent patterns is widely used to discover knowledge from a database. It was originally applied on Market Basket Analysis (MBA) problem which represents the Boolean databases. In those databases, only the existence of an article (item) in a transaction is defined. However, in real-world application, the gathered information generally suffer from imperfections. In fact, a piece of infor...

The initial postbuckling behavior and imperfection sensitivity of truss-type structures in which the joints do not transmit moments is determined by means of the Lyapunov-SchmidtKoiter approach. Such structures possess local buckling modes involving the buckling of individual members, and global modes involving axial deformations of all members but no member buckling. Of particular interest is ...

Nowadays geographic vector data is produced both by public and private institutions using well defined specifications or crowdsourcing via Web 2.0 mapping portals. As a result, multiple representations of the same real world objects exist, without any links between these different representations. This becomes an issue when integration, updates, or multi-level analysis needs to be performed, as...

Due to the imperfection inherent in real world data, future traffic information services like navigation systems have to deal with missing, uncertain, vague and imprecise information. We argue that revealing the imperfection instead of cleaning data as in today’s services will result in higher user acceptance of a service. Such a service can give additional information on how good its returned ...
