In this paper, a comprehensive study on the performance of parallel plate and rectangular micro channel counter flow heat exchangers is presented. The geometrical parameters of the two configurations are optimized for a given heat transfer rate, effectiveness and pressure drop. In case of rectangular micro channel counter flow heat exchanger, a reduced order model is developed first in which re...

This paper not only addresses how linkages, direct and facilitating linkages, can benefit microfinance institutions – and particularly in jurisdictions where the Savings Group Outreach involvement is particularly low, but also illustrates ways and means whereby group lending and other more recent innovative methods used by micro lenders to secure repayments, could increase the desired effects, ...

It is often assumed that one-on-one dialogue with a tutor, which involves micro-steps, is more effective than conventional step-based tutoring. Although earlier research often has not supported this hypothesis, it may be because tutors often are not good at making micro-step decisions. In this paper, we compare a micro-step based NL-tutoring system that employs induced pedagogical policies, Cor...

The present study investigated instabilities of immiscible liquid-liquid two-phase laminar flow in micro channel systems. Four representative flow patterns, i.e. stratified flow, stratified wavy flow, stratified flow with inclined interface and annular flow, were observed due to the difference of channel dimension of the organic-phase flow and physical properties of liquids.

We develop a general two-sided micro-matching framework with heterogeneous workers and machines that permits a complete analysis of neutral technical progress commonly used in neoclassical production theory, without a priori restrictions on the functional forms of the production technology. We use the concept of “production core” to determine stable task assignments and the corresponding factor...

The ability to manufacture and manipulate components at the micro-scale is critical to the development of micro systems. This paper presents the technique to manipulate micro/nano parts at the micro/nano-scale using an integrated Focused Ion Beam (FIB) system composed of scanning electron microscope, micro manipulator and gas injection system. Currently the smallest gears manufactured with trad...

The IETF Mobile IPv6 protocol has been developped to manage global (macro) mobility. It is not adapted to local (micro) mobility since it does not support any kind of hierarchy. This report presents a hierarchical protocol, built on top of Mobile IPv6, that separates local mobility (within a site) from global mobility (across sites) management. Local handoffs are managed locally and transparent...

Data Mining is best-known for its analytical and prediction capabilities. It is used in several areas such as fraud detection, predicting client behavior, money market behavior, bankruptcy prediction. It can also help in establishing an educational ecosystem, which discovers useful knowledge, and assist educators to take proactive decisions to boost student performance and employability. This p...

As there is little doubt that the perception of one’s acoustic environment is mainly driven by noticed sound events, an environmental sound policy approach with a focus on the local urban neighborhood scale should address all noticeable sound events. These sound events have in common that they are not easily predictable, and that they show a very strong spatial variability. Dense urban sound mo...
