The energy balance of residential blocks in different climate zones is simulated and analysed. influence characteristics on the residential-scale budget clarified, temporal evolution patterns sensible heat flux, latent flux storage surface are obtained. From perspective distribution, ENVI-met simulation software used to explore laws change scale during summer winter three representative cities ...

Alzheimer’s disease (AD) is considered a slow neuronal dysfunction process through hypoxia, ischemia and leads to apoptosis mediated senile plaques and neurofibrillary tangles (NFTs). Due to non-invasive approach of plaque characterization, computational techniques based on Brownian dynamics simulation are unique to speculate the electrostatic and kinetic properties of Acetylcholinesterase (ACh...

This paper presents the design and implementation of a cyberinfrastructure for End-to-End Environmental Exploration (C4E4). The C4E4 framework addresses the need for an integrated data/computation platform for studying broad environmental impacts by combining heterogeneous data resources with state-of-the-art modeling and visualization tools. With Purdue being a TeraGrid Resource Provider, C4E4...

Mobility is the key to contemporary life. While most research activities during recent years concentrated on the representation and modeling of moving objects within GIS environments, analysis tasks have been sorely neglected, especially in the field of environmental GIS. This paper provides an overview of the sparse analysis methods available for dynamic point objects. The methods are classifi...

The objective of this paper is to present a methodology for the integration Computational Fluid Dynamics (CFD) microclimate simulation and Geographic Information System (GIS). first workflow involves attribution spatial coordinates point data extracted from CFD, implementation an SQLite database, connection database visualise use information on environmental comfort variables. second georeferen...

Most businesses of today are increasingly becoming dependent on computer systems in their daily operation. Businesses need to respond quickly and accurately to be able to compete in their rapidly changing envi ronments. It is important that organizations and businesses become aware of the gain that could be realized by applying Integrated Computer Aided Software Engineering to their systems des...

Developing Multiuser Virtual Environments (MUVE) is a very complex task since it involves several engineering domains aspects such as, Virtual Reality, Cooperative Work and Distributed Systems. Furthermore, existing technologies like, graphics capabilities, processing power and network bandwidth, are permanently evolving. For MUVE systems to be successfully developed they must not only deal wit...

This paper describes an experiment evaluating the application of formal tech niques to the modelling and development of a security critical system to high IT SEC levels of assurance The experiment has been done in a commercial envi ronment by engineers working within an existing development process Two in dependent teams of engineers in British Aerospace have been concurrently devel oping a mes...
