A semi-analytical solution is presented using method of Laplace transform for the transient pulse electroosmotic flow (EOF) Maxwell fluid in a circular micro-channel. The driving mode EOF here considered as an ideal rectangle pulse. involves solving linearized Poisson-Boltzmann (P-B) equation, together with Cauchy momentum equation and general constitutive equation. results show that profiles v...

We present a computational fluid dynamics (CFD) model for the swimming of micro organisms with a single helical flagellum in circular channels. The CFD model is developed to obtain numerical solutions of Stokes equations in three dimensions, validated with experiments reported in literature, and used to analyze the effects of geometric parameters, such as the helical radius, wavelength, radii o...

This paper reports on the state-of-the-art of technologies for the design and fabrication of MEMS micro-mirrors. We discuss the major design issues, considerations, calculations and restrictions of micro mirrors. The materials employed for the reflective surfaces are described along with their properties. The materials used for the static and dynamic MEMS micro structures as well as the differe...

Because of its kinetic nature and computational advantages, the Lattice Boltzmann method (LBM) has been well accepted as a useful tool to simulate micro-scale flows. The slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. The most used slip boundary condition is the Maxwell slip model. The results of Maxwell slip model are affected by the ac...

the aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (nepcm) slurry as a cooling fluid instead of pure fluid. a threedimensional model of a circular channel using water slurry of nepcm was developed. the results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

This paper shows firm level micro analysis of information network use and its impact on firm’s productivity. New evidences on economic impacts of IT by type of its application are provided, based on METI’s firm level data of Japanese manufacturers and distributors. It is found that productivity impact of information network use is different, depending on application of network. In addition, due...

Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....

This paper presents the development of a standard classification and coding system for micro-scale assembled devices that can link micro-assembly concepts and technologies to the attributes of the assembly components and their interrelationships that define the assembled device/product. The proposed system is based on an n-digit coding of both individual parts as well as the assembly. The codin...

We developed a four-channel photon counting based Stokes-polarimeter for spatial characterization of polarization effects in second harmonic generation (SHG). We have implemented a calibration technique allowing quantitative measurement of polarization parameters, such as the degree of polarization (DOP), degree of linear polarization (DOLP), degree of circular polarization (DOCP), as well as a...
