Computer simulation of fracture processes remains a challenge for many industrial modelling problems. In a classical finite element method, the non-smooth displacement near the crack tip is captured by refining the mesh locally. The number of degrees of freedom may drastically increase, especially in three dimensional applications. Moreover, the incremental computation of a crack growth needs f...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

A model of the RF feedback system for PEP-II has been developed to provide time-domain simulation and frequency-domain analysis of the complete system. The model includes the longitudinal beam dynamics, cavity fundamental resonance, feedback loops, and the nonlinear klystron operating near saturation. Transients from an ion clearing gap and a reference phase modulation from the longitudinal fee...

This document describes the results achieved when simulating the timing rules of the Extended RTP Profile for Real-time Transport Control Protocol (RTCP)-Based Feedback, denoted AVPF. Unicast and multicast topologies are considered as well as several protocol and environment configurations. The results show that the timing rules result in better performance regarding feedback delay and still pr...

Immersion in a Virtual Environment (VE) is known to produce symptoms similar to those of motion sickness, termed ‘Virtual Simulation Sickness’ (VSS), and there is evidence that people adapt or, more accurately, habituate to the effects. We aimed to quantify this habituation by immersing 70 people on ten occasions each. Ten subjects were exposed every day, ten more every 2, 3, 4, 5, 6 and 7 days...

OMP Simulation Results in IP Networks Károly Farkas High Speed Networks Laboratory Department of Telecommunications and Telematics Budapest University of Technology and Economics, H-1117, Pázmány P. s. 1/D., Budapest, Hungary E-mail: [email protected] Abstract These days the use of Internet almost everywhere is not surprising. However, the used traffic management solutions in the Net a...

MOTIVATION Simulations are an essential tool when analyzing biochemical networks. Researchers and developers seeking to refine simulation tools or develop new ones would benefit greatly from being able to compare their simulation results. SUMMARY We present an approach to compare simulation results between several SBML capable simulators and provide a website for the community to share simula...

In situ simulation, simulation that is physically integrated into the clinical environment, provides a method to improve reliability and safety in high-risk areas. Deliberate practice and integration of teamwork skills in the time-pressured clinical environment provides great realism and is a rich resource to identify latent threats and system issues that can compromise patient safety. However,...
