background: aneurysm is a blood-filled bulge in the wall of vessels that occurred in abdominal aortic and cerebral vessels. the dilation of artery leads to aneurysm. methods: three dimensional modelling was utilized for a patient with cerebral aneurysm and a normal subject, and additional fluid-structural interaction simulation was performed. we consider pulsatile blood velocity as inlet, and b...

Telephone interviews were initially conducted for fi ve cases using a hypothesis-generating questionnaire. These interviews revealed that all fi ve cases worked in the Brisbane Central Business District (CBD) and had eaten takeaway sushi as a lunch meal in the fi ve days prior to their illness. Four cases reported eating takeaway sushi rolls from the same sushi takeaway outlet (outlet A) and on...

Hydrocyclones have been used as an operational tool to separate liquids from solids in different industries for more than 50 years. Considering the importance of this issue, many experimental and numerical attempts have been made to estimate the performance of this tool regarding the resulting pressure drop and the separation efficiency (particles separation limit diameter...

Using experimental models along with conducting numerical analysis have been widely used in performance recognition and optimization of hydraulic equipments. Numerical modeling has lower cost rather than experimental one; however practical tests are commonly used because of the hydraulic structure importance especially in dams. Meanwhile numerical methods could be used for future designs throug...

In this paper, a detailed 3D modelling of flow and coupled heat and mass transport in a channel coated with adsorbing material is presented. A comparative study between a simplified 1D model and the detailed 3D model is carried out. Both 3D and 1D predictions are compared with experimental data available from literature as well. The time-dependent variation of temperature and heat flux distribu...

The outlet pressure box culvert is often used as the drainage building of a pumping station. Because its compact structure, it produces transverse flow velocity and then forms poor patterns, such bias flow, reflux, separation, which affect discharge efficiency Based on combination physical model test numerical simulation, hydraulic characteristics an eccentric tapering were analyzed. Focusing p...

Over the past two decades, mass loss from the Greenland Ice Sheet (GrIS) has accelerated and contributed to global sea level rise. This has been partly attributed to dynamic changes in marine terminating outlet glaciers. Outlet glaciers at the northern margin of the ice sheet drain 40% of its area but are comparatively less well-studied than elsewhere on the ice sheet (e.g., central-west or sou...

The stationary discontinuous armatures that are used in permanent magnet linear synchronous motors (PMLSMs) have been proposed as a driving source for transportation systems. However, the stationary discontinuous armature PM-LSM contains the outlet edges which always exist as a result of the discontinuous arrangement of the armature. For this reason, the high alteration of the outlet edge coggi...

We present a dynamic reputation model of news reporting by a profitmaximizing media outlet whose credibility is uncertain to the public. In each period, the media outlet chooses its source of news: a costly independent investigation or, possibly, a free report prepared by an interest group. The revenue of the media outlet consists of the subscription fees for the public and the access fees for ...
