In this paper, a new method is introduced to solve a two-dimensional Fredholm integral equation. The method is based on the approximation by Gaussian radial basis functions and triangular nodes and weights. Also, a new quadrature is introduced to approximate the two dimensional integrals which is called the triangular method. The results of the example illustrate the accuracy of the proposed me...
This paper presents global and point-wise comparisons of experimental measurements and numerical simulation results of electro-osmotically driven flows in two elementary micro-channel configurations, a straight channel with a groove and a T-junction channel. The microchannels are made by photolithography using poly-dimethylsiloxane (PDMS), a type of silicon product, which is transparent, and el...
We present a complete numerical algorithm of isolating all the real zeros of a zero-dimensional triangular polynomial system Fn ⊆ Z[x1, . . . , xn]. Our system Fn is general, with no further assumptions. In particular, our algorithm successfully treat multiple zeros directly in such systems. A key idea is to introduce evaluation bounds and sleeve bounds. We also present a much more efficient al...
We present some algorithms which construct a triangular graph given a set of points, where each face of the graph complies with the Delaunay criteria. Then we develop an linear time algorithm to construct the contour of such a triangular graph, where each face is coloured either black or white. Our techniques avoid expensive trigonometric computations. We intoduce our algorithms for the 2-dimen...
The Fluorescence2D is free software that allows analysis of two-dimensional fluorescence spectra obtained using the accelerated "triangular" acquisition schemes. The software is a combination of Python and MATLAB-based programs that perform conversion of the triangular data, display of the two-dimensional spectra, extraction of 1D slices at different wavelengths, and output in various graphic f...
Abstract To improve the heat transfer performance of microchannels, a novel microchannel embedded with connected grooves crossing two sidewalls and bottom surface (type A) was designed. A comparative study conducted regarding performances type microchannels on their (including types B C), or D) as well smooth rectangular E) via three-dimensional numerical simulation experimental validation (at ...
Cells migrate in vivo within three-dimensional (3D) extracellular matrices. Cells also migrate through 3D longitudinal channels formed between the connective tissue and the basement membrane of muscle, nerve, and epithelium. Although traction forces have been measured during 2D cell migration, no assay has been developed to probe forces during migration through confined microenvironments. We th...
Here we describe a simple approach to fabricate robust three-dimensional periodic porous nanostructures inside the microchannels. In this approach, the colloidal crystals were first grown inside the microchannel using an evaporation-assisted self-assembly process. Then the void spaces among the colloidal crystals were filled with epoxy-based negative tone photoresist. After subsequent developme...
