This paper focuses on steady state performance predictions and optimization of the Reverse Osmosis (RO) process utilizing a set of implicit mathematical equations which are generated by combining solution-diffusion model with film theory approach. The simulation results were compared with operational data which are in good agreement having relative errors of 0.71% and 1.02%, in terms of water r...

We characterized a BNL 1.3GHz halfcell SRF gun is tested for GaAs photocathode. The gun already was simulated several years ago via twodimensional (2D) numerical codes (i.e., Superfish and Parmela) with and without the beam. In this paper, we discuss our investigation of its characteristics using a three dimensional (3D) full-wave code (CST STUDIO SUITETM).The input/pickup couplers are sited sy...

We present an accuracy and performance analysis of SimGate – a full-system simulation of the Stargate intermediate-level sensor network device. We also examine ensemble simulations using SimGate and either one or two simulated Mica2 motes using the same criteria. We find that accurate functional behavior and cycle counts (at the full device level) are achievable using SimGate alone, and in conj...

We describe full system simulation of DAISY (Dynamically Architected Instruction Set from Yorktown). At runtime DAISY dynamically translates code for a PowerPC processor into code for an underlying VLIW processor. Our style of simulation can also be used in the context of full system emulation à la SimOS and SimICS. Unlike SimOS and SimICS, DAISY emulation is operating system and device indepen...

This paper presents a measurement-driven, musculoskeletal, full-body simulation model for biomechanical analysis of the double-poling (DP) technique in cross-country skiing. DP is a fast and powerful full-body movement; therefore, it is interesting to examine whether inverse dynamics using static optimization is working for a musculoskeletal full-body model with high accelerations, a large rang...

Introduction: The electromagnetic gyrokinetic (GK) plasma simulation [1] for toroidal magnetic fusion devices has become a standard tool for turbulence analysis. Recently, it has been recognized that transport involving dynamic changes in profiles requires modelling with full f GK methods [2]. In the present work, we report on transport simulations for the FT-2 tokamak plasma with a full f nonl...

This thesis outlines the construction of several types of structured integrators for incompressible fluids. We first present a vorticity integrator, which is the Hamiltonian counterpart of the existing Lagrangian-based fluid integrator [32]. We next present a model-reduced variational Eulerian integrator for incompressible fluids, which combines the efficiency gains of dimension reduction, the ...

Performance models can represent the performance relevant aspects of an enterprise application. Corresponding simulation engines use such models for simulating performance metrics (e.g., response times, resource utilization, throughput) and allow for performance evaluations without load testing the actual system. Creating such models manually often outweighs their benefits. Therefore, recent re...

Profile stiffness is a long standing problem, which may limit the overall performance of H-mode plasmas. In the JET experiment, while strong temperature profile stiffness is observed around the nonlinear threshold of ion temperature gradient, it can be greatly reduced by co-current toroidal rotation in weak magnetic shear plasma [1]. To understand such a mitigation mechanism of the stiffness, w...

This paper describes an audio-visual performance system based on real-time fluid simulation. The aim is to provide a rich environment for works which blur the boundaries between dance and instrumental performance – and sound and visuals – while maintaining transparency for audiences and new performers. The system uses infra-red motion tracking to allow performers to manipulate a real-time fluid...
