Home: A Feeling Rooted in the Heart

Culturally diverse as they are, Asian-American children and youth share quite a few features among themselves. Most of them are children of foreign-born parents who came to America during the post-1965 immigration waves. As they grow up in culturally isolated environment, they are often faced with identity crisis. The society’s racial exclusion makes them feel like “forever foreigners,” while at home or community their American frame of reference is often in conflict with parents’ traditional values. As a result, they develop a flexible concept of identification. In fact, they are a part of but also apart from the American mainstream culture.

A matching algorithm based on hybrid matricesconsisting of reference differences and disparities

INTRODUCTION A common method for extracting depth in-formation from intensity images is based on theprinciples of stereovision. In this method, a pair ofimages is obtained using two cameras displacedfrom each other by a known distance. After deter-mining the stereo correspondence, the distance ofvarious points is computed using triangulation(Jeon et al., 2001). Stereo correspondence is theproblem of finding corresponding points in two ormore images of the same scene, usually assumin…

Three dimensional couette flow and heat transfer through a porous medium with variable permeability

This paper reports research on the effects of variations in injection velocity and permeability on the heat transfer and flow through a highly porous medium between two horizontal parallel plates situated at constant distance with constant suction by the upper plate. Due to this type of variation in injection velocity and in permeability the flow becomes three dimensional. The governing equations are solved by adopting complex variable notations to obtain the expressions for the velocity and temperature field. The skin-friction along the main flow direction and rate of heat transfer are discussed with the help of graphs.
