The evaporation duct height (EDH) can reflect the main characteristics of near-surface meteorological environment, which is essential for designing a communication system under this propagation mechanism. This study proposes an EDH prediction network with multi-layer perception (MLP). Further, we construct multi-dimensional model (multilayer-MLP-EDH) first time by adding spatial and temporal “e...

UNLABELLED Extra cellular matrix (ECM) is a natural cell environment, possesses complicated nano- and macro- architecture. Mimicking this three-dimensional (3-D) web is a challenge in the modern tissue engineering. This study examined the application of a novel 3-D construct, produced by multilayered organization of electrospun nanofiber membranes, for human bone marrow-derived mesenchymal stem...

In universal personal telecommunication (UPT) environments, UPT networks retain information related to incall/outcall registration in UPT user service profiles in order to provide incoming UPT calls for UPT users in any location who have registered at a terminal. As UPT networks support incall registration, terminal users can be different from terminal owners, and several UPT users can register...

We extend the concept of graph isomorphisms to multilayer networks, and we identify multiple types of isomorphisms. For example, in multilayer networks with a single “aspect” (i.e., type of layering), permuting vertex labels, layer labels, and both of types of layers each yield a different type of isomorphism. We discuss how multilayer network isomorphisms naturally lead to defining isomorphism...

We designed multilayer wavelength-selective reflector films by stacking thin-films of transparent polymer. The optimum structure of the multilayer is determined using a combination of characteristic matrix method and a version of genetic algorithm. Such multilayer films can be used in LCD devices to enhance the color saturation of the display. key words: optical design, multilayer, color enhanc...

This article presents findings from five repertory grid interviews conducted in early 2001 to identify attributes of information as an asset. Repertory grid is a technique developed by George Kelly based on his theory of personal constructs. Personal construct theory (PCT) assumes that individuals are their own ‘personal scientists’ who mentally represent the world around them. The method was u...

Work is currently in progress on the following projects: What do experts/novices know about programming. T1 The objective here is to develop a plan-based theory of programming knowledge and to test it empirically with novice and expert programmers. We are also using this theory to study the bugs and misconceptions of novice programmers. Cognitively appropriate programming language constructs.’ ...

Like other constructivist approaches, Personal Construct Theory (PCT) views human activity as a meaning creating process. What human organisms do, is informed by the way they construe events, and in turn assign meaning to those events. Symptoms are a rare, but legitimate part of their activity. They challenge our everyday conceptions regarding human behaviour. From a personal construct perspect...
