In this work\ a new concept for a two!layered micro!channel heat sink with counter current ~ow arrangement for cooling of the electronic components is proposed[ The thermal performance and the temperature distribution for these types of micro channels were analyzed and a procedure for optimizing the geometrical design parameters is presented[ While the power supply system of the two!layered des...

This study reports the morphological, anatomical and agar content difference among various species of Gracilaria. The cortex was found 1 2 layered in G. edulis and G. eucheumatoides whereas 5 6 layered in G. foliifera and G. crassa. The medulla was 6 8 layered in G. edulis, 10 11 layered in G. foliifera, 14 15 layered in G. eucheumatoides and 8 10 layered in G. crassa. Similarly, distinct varia...

A mathematical model to describe the principle of layered manufacturing and layered fabrication error is presented in this paper. In this model, the layered manufacturing process is characterized by the model decomposition and material accumulation. A 3D design model is represented by a set of points with sequence functions to correlate the layered processing information. Iso-sequence planes ar...

Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived. Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetri...

Triple-layered microparticles comprising poly(D,L-lactide-co-glycolide, 50:50) (PLGA), poly(L-lactide) (PLLA) and poly(ethylene-co-vinyl acetate, 40 wt.% vinyl acetate) (EVA) were fabricated using a one-step solvent evaporation technique, with ibuprofen drug localized in the EVA core. The aim of this study was to investigate the drug release profiles of these triple-layered microparticles in co...

Layered Multicasting with layered source coding scheme enables efficient distribution of real-time streaming media over heterogeneous networks such as the Internet. In layered multicast, rate control is required to cope with congestion quickly because packet losses in a layer with higher priority lead greater degradation of received quality. In addition, rate control for layered multicast is re...

We study the capabilities of two-layered perceptrons for classifying exactly a given subset. Both necessary and sufficient conditions are derived for subsets to be exactly classifiable with two-layered perceptrons that use the hard-limiting response function. The necessary conditions can be viewed as generalizations of the linear-separability condition of one-layered perceptrons and confirm the...

We propose a “layered structured network diagram,” which consists of layers of time differences. We have implemented a tool called “NeL” for handling layered structured network diagrams. Layered structured network diagrams have multiple accumulated layers and are not single diagrams. Using this layered structure, time differences can be included in one diagram. In addition, various type of info...

We introduce a new graph drawing convention for 3D layered drawings of directed graphs. The vertex set is partitioned into layers with all edges pointing in the same direction. The layers occupy parallel planes and vertices in each layer occupy two parallel lines. Thus, the traditional 2D layered drawing of a directed graph is split into two vertical walls each containing a 2D layered drawing. ...
