A numerical study of hemodynamic parameters of pulsatile blood flow is presented in a stenotic artery with A numerical study of hemodynamic parameters of pulsatile blood flow is presented in a stenotic artery with non-Newtonian models using ADINA. Blood flow was considered laminar, and the arterial wall was considered rigid. Studied stenosis severities were 30, 50, and 70% of the cross-section...

Simulation for ATM Networks G. Kesidis, A. Singh, D. Cheung and W.W. Kwok E.& C.E. Dept, University of Waterloo Waterloo, ON, Canada, N2L 3G1 email: fg.kesidis,[email protected] Abstract| We describe an ATM network simulator that uses Markov-modulated uid models for the sources as well as uid leaky buckets and uid bandwidth schedulers. The generalized processor sharing (GPS) and \idli...

Robustness is a key factor for real-time positioning and navigation, especially high-speed vehicles. While visible light (VLP) based on LED illumination image sensors widely studied, most of the VLP systems still suffer from high latency blurs caused by movements. In this paper, robust system vehicles proposed deep learning data-driven approach. The can significantly increase success rate decod...

Transient microwave reflectance (TMR) measurements are used to characterize the minority carrier lifetime and background concentration of unintentionally doped (UID) Ga0.5As0.5Sb lattice matched InP at room temperature. A p-i-n sample is measured, with UID GaAsSb as intrinsic absorber. In addition GaAsSb, we determine doping a buried n+ layer. The measured lifetimes 20.5 ± 6.3 0.56 0.23 µs for ...

Flow field and heat transfer of a nanofluid, whose non-Newtonian behavior has been demonstrated in the laboratory, in a square enclosure have been numerically modeled and investigated. To estimate the viscosity of nanofluid, experimental data of Hong and Kim, 2012 have been used, and a new model has been proposed. Finally, the obtained results have been compared to those of Newtonian behavior. ...

We propose to use uid model based time-driven simulation to simulate high speed networks. For single class uid in feedforward networks, we prove that the error introduced by discretizing a uid model is within a deterministic bound proportional to the discretization interval length and is not related to the network size. We show that uid simulation ooers the exibility to trade accuracy for eecie...

We study a coupled uid-structure system. The structure corresponds to a part of the boundary of a domain containing an incompressible viscous uid. The structure displacement is modeled by an ordinary di erential equation. We prove the local null controllability of the system when the control acts on a xed subset of the uid domain.

This paper studies the uid models of two-station multiclass queueing networks with deterministic routing. A uid model is globally stable if the uid network eventually empties under each nonidling dispatch policy. We explicitly characterize the global stability region in terms of the arrival and service rates. We show that the global stability region is de+ned by the nominal workload conditions ...

A system is disclosed for condensation particle counting in conjunction With modifying an aerosol to enhance the for mation and groWth of droplets of a selected Working ?uid, preferably Water. Before saturation With the Working ?uid, the aerosol is exposed to an aerosol modifying component, preferably a vapor including molecules that are adsorbed onto surfaces of the particles or other elements...

Effective thermal conductivity of mixtures of  uids and nanometer-size particles is measured by a steady-state parallel-plate method. The tested  uids contain two types of nanoparticles, Al2O3 and CuO, dispersed in water, vacuum pump  uid, engine oil, and ethylene glycol. Experimental results show that the thermal conductivities of nanoparticle– uid mixtures are higher than those of the bas...
