We present a first set of results concerning stellar evolution of rotating low-mass stars. Our models include fully consistent transport of angular momentum and chemicals due to the combined action of rotation induced mixing (according to Maeder & Zahn 1998) and element segregation. The analysis of the effects of local variations of molecular weight due to the meridional circulation on the tran...

The arrangement graph An;k is not only a generalization of star graph (nÿ k ˆ 1), but also more ̄exible. In this investigation, we elucidate the problem of embedding of multiple spanning trees in an arrangement graph with the objective of congestion-free. This result is to report how to exploit 2…nÿ k† edge disjoint spanning trees in an arrangement graph, where each congestion-free spanning tre...

A Personal Distributed Environment (PDE) embraces a user-centric view of communications that take place against a backdrop of multiple user devices, each with its distinct capabilities, in physically separate locations. This paper provides an overview of a Personal Distributed Environment and some of the research issues related to the implementation of the PDE concept that are being considered ...

In this paper we address object-oriented component integration issues. We argue that traditional framework customization techniques are inappropriate for component-based programming since they lack support for non-invasive, encapsulated, dynamic customization. We propose a new language construct, called a pluggable composite adapter, for expressing component gluing. A pluggable composite adapte...

INTRODUCTION Historical biographies facilitate teaching the 'nature of science'. This case study focuses on how Nikolai Vavilov's unrelenting sense of purpose, courage, and charismatic personality was maintained during violent revolutionary change in Russia. CASE DESCRIPTION The rediscovery of Gregor Mendel's laws of inheritance provided Vavilov with a scientific foundation for crop improveme...

As the information management paradigm shifts from data management to knowledge management, active rule support for various information services has become a practical approach to add intelligence to the existing information management systems. Various active rule systems have been developed using different rule description languages and, yet, their business logics are not sharable with each ot...

After mindfulness is defined, a brief history of the research on the topic to date is reviewed. This work essentially falls into three categories: health, business, and education. Considerations of mindlessness as a social issue are then addressed. A brief introduction to the articles in this issue follows. These articles speak to mindfulness as it relates to potential solutions to social probl...

In this paper, author uses set theory to construct a logic model of abstract figure from binary relation. Based on the uniform quantified structure, author gives two logic system for graph traversal and graph coloring respectively, moreover shows a new method of cutting graph. Around this model, there are six algorithms in this paper including exact graph traversal, Algebra calculation of natur...

as social health is a condition-driven, dynamic and fluid concept, it seems necessary to construct and obtain a national and relevant concept of it for every society. providing an empirical back up for iran's concept of social health was the aim of the present study.this study is an ecologic study in which available data for 30 provinces of iran in 2007 were analyzed. in order to prove construc...

We propose a new probabilistic extension to the event calculus using the probabilistic logic programming (PLP) language ProbLog, and a language construct called the annotated disjunction. This is the first extension of the event calculus capable of handling numerous sources of uncertainty (e.g. from primitive event observations and from composite event definitions). It is also the first extensi...
