In the U.S., the mid and late 1990s was a boom period in many ways that included an expanding economy, a growing emphasis upon the value of people's working knowledge, and a range of new Information Technology (IT) applications and information services that depended upon computer networking often the Internet. These themes were represented in professional discourse by a special emphasis upon "k...

In this paper, we present an overview of our research project with Gaia, a development infrastructure for ubiquitous applications. This infrastructure is based on three main elements: a component-based middleware operating system that provides a generic computational environment for ubiquitous computing, an application model that defines a standard mechanism to build ubiquitous applications, an...

abstract:â green spaces, especially urban gardens have been a subject of study in many countries for a long time, but the subject has been mostly overlooked in iran. therefore, this study tries to analyze the changes in land use and how we can protect green spaces (gardens) in jahrom in line with sustainable development in 1996-2006. the data in this study were collected through local investiga...

In Pair Programming – a software development technique that is part of Extreme Programming (XP) – two developers work side by side, on a single computer, to jointly produce an artifact. It has been reported that Pair Programming can be accounted for the development of higher quality software in half the time it required a single programmer. Pair programmers are meant to be collocated since they...

Gas exchange is essential for multicellular organisms. In contrast to the circulatory systems of animals, land plants have tissues with intercellular spaces (ICSs), called aerenchyma, that are critical for efficient gas exchange. Plants form ICSs by two different mechanisms: schizogeny, where localized cell separation creates spaces; and lysogeny, where cells die to create ICSs. In schizogenous...

one of the important problems in the urban development process in the world has been land use and planning for urban sustainability. considering this important issue, this study investigates spatial analysis and urban land use planning in dogonbadan. this research is applied- analytical and by applying land extension index and hensen model intends to study and plan urban land use in this city. ...
