Many fire evacuation models have been proposed in recent years to better simulate such as an emergency situation. However most of them do not respect a recommendation of fire evacuation experts regarding the fact that evacuees should follow the boundaries of obstacles or wall to find the exits when their visibility is limited by smoke. This paper presents an agent-based evacuation model with Sm...

Large-scale controlled evacuations require emergency services to select evacuation routes, decide departure times, and mobilize resources to issue orders, all under strict time constraints. Existing algorithms almost always allow for preemptive evacuation schedules, which are less desirable in practice. This paper proposes, for the first time, a constraint-based scheduling model that optimizes ...

OBJECTIVE To review the management and some of the recent advances in acute haemorrhagic stroke. DATA SOURCES Articles and published reviews on acute haemorrhagic stroke. SUMMARY OF REVIEW Hypertensive intracerebral haemorrhage or subarachnoid haemorrhage (SAH) from a ruptured intracranial saccular aneurysm are the commonest causes for an acute haemorrhagic stroke. Both lesions are often cl...

Objective: The present study is aimed to investigate in vitro thrombolytic activity of three Bangladeshi medicinal plants Averrhoa bilimbi (Oxalidiaceae), Clerodendrum viscosum (Verbanaceae) and Drynaria quercifolia (Polypodiaceae). Materials and methods: Each the plant was extracted with methanol at room temperature and the concentrated methanolic extracts (MEF) were fractionated by the modifi...

Emergency situations involving a large number of people may develop into disasters. One example of such emergency situation is fire evacuation in a building or crowded area. Although crowd evacuation simulation has been an active research area for many years, little research focuses on simulating the evacuation process with a Leader-Follower Model which shows the role of leaders in the evacuati...

It’s an important evaluation architecture safety standards about personnel emergency evacuation under the fire condition, from the development trend of university gymnasium, it’s relatively rare that based on comprehensive evaluation the multi-functional gymnasium fire conditions personnel emergency evacuation study and there is no mature evaluation model can be applied to practical operation l...

INTRODUCTION We investigated the effect of progressive haemodilution on the dynamics of fibrin clot formation and clot microstructure using a novel rheological method. The technique measures clotting time (TGP), clot strength (G`GP), and quantifies clot microstructure (df) at the incipient stages of fibrin formation. We use computational modelling to examine the relationship between structure a...

materials and methods in the present study, a potent nk-producing strain was isolated from cow milk and identified. to enhance the yield of nk, effect of various parameters such as ph, temperature, carbon source, nitrogen source and inoculum size were optimized. strain improvement of p. aeruginosa cmss was done by random uv-mutagenesis. nattokinase was partially purified and the activity was de...

Title of Dissertation: AN INTEGRATED OPTIMAL CONTROL SYSTEM FOR EMERGENCY EVACUATION Ying Liu, Doctor of Philosophy, 2007 Directed By: Professor Gang-Len Chang Department of Civil and Environmental Engineering How to effectively control evacuation traffic has emerged as one of the critical research issues in transportation community, due to the unusually high demand surge and the often limited ...
