Atrium is a popular architectural feature utilized widely by building designers and owners to bring various benefits such as adequate daylight, circulation spaces and surfaces for landscape applications. But atrium problems in tropical climates such as excessive daylight, glare and high temperature, which lead to increase building energy demand, have been reported. Atrium has been used with var...

introduction reducing and optimizing energy consumption and consequently environmental pollution reductions, besides improving building performance providing occupants comfort conditions, make the building's concept closer to the concept of green building and sustainability. once the decision to build green has been made, one of the first steps in the green design process is to establish f...

The Nature Conservation Society of South Australia (NCSSA) Bushland Condition Monitoring Program and the South Australian Biodiversity Assessment Tool (SABAT) address this shortcoming, and provide an innovative approach to building community capacity in vegetation management. The program allows conservation volunteers, landholders and extension professionals to conduct an effective evaluation o...

Building upon earlier work of T. Brady, we construct locally CAT(0) classifying spaces for those Artin groups which are three dimensional and which satisfy the FC (flag complex) condition. The approach is to verify the “link condition” by applying gluing arguments for CAT(1) spaces and by using the curvature testing techniques of M. Elder and J. McCammond.

The branch of fluid mechanics is also familiar with biomechanics recently. The combination of hydrodynamic and mechanical specification of the flow can reach the complex description of the liquid flow in the hydraulic system. The hydraulic system can represent the airways and ventilation system, and external blood circulation. An important role in the study of hemo-transport has its interaction...

This paper describes an experiment that compares behaviour in small groups when they carry out a task in a virtual environment (VE) and then continue the same task in a similar real-world environment. The purpose of the experiment was not to examine task performance, but to compare various aspects of the social relations between the group members in the two environments. Ten groups of 3 people ...

Discrete symmetries are commonplace in field theoretical models but pose a severe problem for cosmology since they lead to the formation of domain walls during spontaneous symmetry breaking in the early universe. However if one of the vacuua is favoured over the others, either energetically, or because of initial conditions, it will eventually come to dominate the universe. Using numerical meth...

The nonlinear incompressible Navier-Stokes equations with boundary conditions at far fields and solid walls is considered. Two different formulations of boundary conditions are derived using the energy method. Both formulations are implemented in both strong and weak form and lead to an estimate of the velocity field. Equipped with energy bounding boundary conditions, the problem is approximate...

The coupled interaction between a sloshing fluid in a partially-filled container suspended as a bifilar pendulum is investigated. The sloshing fluid has a free-surface upon which waves are generated this fluid contributes a restoring force to the container motion by its weight through the wire suspensions and the free-surface waves may either enhance or diminish the restoring force through hydr...
