Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady ...

A dexterous micro manipulation system was developed for applications such as assembling micro machines, manipulating cells, and micro surgery. We have proposed a concept of a two-fingered micro hand, and designed and built a prototype. We succeeded in performing basic micro manipulations, including the grasp, release, and rotation of a microscopic object. The micro hand is controlled with a pos...

In electronic auction applications, small-value merchandise is often distributed. We call this kind of auction micro auction. Compared to traditional general-purpose electronic auction, micro electronic auction has its own special requirements. Especially, micro auction must be very efficient: the cost of the auction protocol must not be over the cost of the merchandise for sale. Although the m...

With the aim of improving the performance of Mobile IP, several proposals based on the concept of micro-mobility have been proposed. In this an analytical model for the performance evaluation of a number of handover micro-mobility schemes is developed.

This paper presents the experimental validation of automatic dexterous in-hand manipulation of micro-objects. Currently, precise handling of micro-objects is still a challenge especially when large rotations are required. Indeed, the current dexterity of microgrippers is still very low and only some small range rotations have been shown. Although, the robotic hands in the macroscale have better...

In this paper we explain the building of an English lexicon of adjectives and their semantic orientations. Rather than defining the semantic orientation of a term as a single value, we induce many real values representing the semantic orientation of that term being used in different domains. The automatic building of this resource has been based on the construction of graphs from conjunctive ex...

For the microelectronics manufacturing industries that have uncertain demand, high volume cost and Oligarchs characteristics, we often discuss the possibility of competitors on the capacity of strategy. First of all we use the industry data to analysis the manufacturing cost, demand and the historical situation of the revenue and we also discuss the influence about the uncertain demand and high...

ISIS is a system for building applications consisting of cooperating, distributed processes. Here we present a new implementation of the ISIS system, geared towards modern microkernel technology. We have adopted similar strategies, such as using basic internal mechanisms for efficiency, external services to implement policies, and light-weight user space constructs for simplicity. The resulting...
