Macroscopic modeling and simulations of room evacuation [PDF]
, 2013 We analyze numerically two macroscopic models of crowd dynamics: the classical Hughes model and the second order model being an extension to pedestrian motion of the Payne-Whitham vehicular traffic model.

Mapping the X-Ray Emission Region in a Laser-Plasma Accelerator [PDF]
, 2011 The x-ray emission in laser-plasma accelerators can be a powerful tool to understand the physics of relativistic laser-plasma interaction. It is shown here that the mapping of betatron x-ray radiation can be obtained from the x-ray beam profile when an ...

A Reverse-Osmosis Model of Apoptotic Shrinkage
Frontiers in Cell and Developmental Biology, 2020 The standard theory of apoptotic volume decrease (AVD) posits activation of potassium and/or chloride channels, causing an efflux of ions and osmotic loss of water.

Effects of Flow Coefficient on Turbine Aerodynamic Performance and Loss Characteristics
International Journal of Aerospace Engineering, 2022 The effects of flow coefficient on the gas flow and loss characteristics inside the high-pressure turbine is investigated using a numerical simulation. In this paper, the midspan of the first stator of the “Lisa” 1.5 stage high-pressure turbine is used ...

Handling congestion in crowd motion modeling [PDF]
, 2010 We address here the issue of congestion in the modeling of crowd motion, in the non-smooth framework: contacts between people are not anticipated and avoided, they actually occur, and they are explicitly taken into account in the model.

Towards Solutions of Seepage Problems
Sultan Qaboos University Journal for Science, 1997 Flow rates are traditionally used for solving seepage problems in soils. In this paper, the method of fragments is presented as a good alternative for solving seepage problems.

Tikrit Journal of Engineering Sciences, 2016 The seepage through a permeable soil under hydraulic structure exerts uplift pressure and may carry soil particles there by leads to piping. This paper concerns to study the effect of using intermediate sheet pile under the apron of hydraulic structure ...

Numerical path integral calculation of the probability function and exit time: an application to non-gradient drift forces [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 We provide numerical solutions based on the path integral representation of stochastic processes for non-gradient drift Langevin forces in the presence of noise, to follow the temporal evolution of the probability density function and to compute exit times even for arbitrary noise.

Effect of Changes in Hydraulic Conductivity on Exit Gradient at Selected Levee Systems Using Numerical Models [PDF]
The Open Hydrology Journal, 2014 The objective of the research was to provide a better understanding of the influence of hydraulic conductivity on the exit gradient for a rectangular block representing a root zone. A critical area of concern to design engineers is the exit gradient at the toe of the levee and other sensitive areas.
