The dynamic adsorption of Pb(II) ions from aqueous solutions using a granulated activated carbon and an activated carbon cloth has been studied using fixed bed adsorption column. The breakthrough curves at different hydraulic loading rates (HLR), bed depth and feed concentration (Co) have been examined. The breakthrough time at any given concentration of the effluent decreases with increasing h...

This paper implements efficient techniques for cloth simulation in the area of cloth model, numerical integration, collision detection and response. The whole procedure combines the accurate bending model with implicit integration and collision response. Collision response remains a serious difficulty in cloth simulation, especially with implicit integration. We propose a general scheme that in...

OBJECTIVE The aim of this study was to compare the efficacy of cloth masks to medical masks in hospital healthcare workers (HCWs). The null hypothesis is that there is no difference between medical masks and cloth masks. SETTING 14 secondary-level/tertiary-level hospitals in Hanoi, Vietnam. PARTICIPANTS 1607 hospital HCWs aged ≥18 years working full-time in selected high-risk wards. INTER...

Even though a particle model based on the mechanical properties of woven cloth has been proposed by Breen et al[l], there are problems to describe cloth behavior precisely and reflect cloth dynamics. In this paper, we describe a precise relationship between measured mechanical properties of cloth and the particle model. Moreover, a collision model describing the rotation as well as move of part...

This paper presents a real-time simulation method for coupling of cloth and fluids computed by using Smoothed Particle Hydrodynamics (SPH). To compute interaction between cloth consisting of several polygons and fluid particles, the distance between cloth to the particle have to be calculated. It is computationally expensive because we have to compute the distance to the faces, edges and vertic...

This paper presents a state of the art in the cloth simulation methods and two case studies on how to simulate ancient and high fashion garments with our new Fashionizer platform. The first application concerns the simulation of garments in a cultural heritage project, the Lifeplus project, where we had to simulate in real-time ancient roman clothes. The second application is the simulation of ...
