Abstract This paper focuses on the application of multi-fidelity surrogate modelling to characteristics a flow as it changes with parameter. provides insight into potential combining approaches varying fidelities computational fluid dynamics methods parameter space exploration. A limited number trusted high-fidelity large eddy simulation data points, in combination an extended study using lower...

Laser-assisted flow-visualization experiments and tracer gas concentration tests were conducted for the wall-mounted and jet-isolated range hoods to examine the physical mechanisms and relative magnitudes of hood spillages. The effects of a mannequin standing in front of the test rig and walk-by motions (which are situations always encountered in kitchens) were emphasized. The results showed th...

In this study, we explored the efficacy of upper-room ultraviolet germicidal irradiation (UVGI) in reducing the concentration of Serratia marcescens and Mycobacterium bovis bacille Calmette-Guérin (BCG) aerosols in enclosed places. We constructed a facility (4.5 m x 3 m x 2.9 m) in which both ceiling- and wall-mounted UV fixtures (UV output: 10W and 5W respectively) were installed. The use of c...

Left ventricular mass, derived from echocardiographic measurement of left ventricular wall volume, was compared with simple vectorcardiographic and electrocardiographic voltage measurements in 36 patients with left ventricular enlargement and 7 normal subjects. Left ventricular wall volume was obtained by subtracting the volume of the ventricular cavity, calculated as the cube of the ultrasound...

This investigation is a three dimensional comprehensive heat transfer analysis for partially differentially heated enclosure with the vertical fin mounted on the hot wall. The thermal lattice Boltzmann based on D3Q19 method is utilized to illustrate the effects of vertical fins and nanoparticles on the flow and thermal fields. The effects of Rayleigh number and different arrangement of fins on ...

Logvinenko [Perception 31, 201 (2002)] asserts that Adelson's wall-of-blocks illusion [Science 262, 2042 (1993)], where identical gray-cube surface tops appear to differ in brightness, arises when the surfaces surrounding the cube tops are shadow compatible, creating a concomitant illusion of transparency. We replicated Logvinenko's main findings in the chromatic domain across three experiments...

The novel concept of the ET-HMPD, which consists of a Head-Mounted Projection Display (HMPD) with an integrated Eye-Tracking (ET) capability, was recently presented as well as the design of some of its components [Curatu, Hua and Rolland, Proceedings of the SPIE 5875, 2005]. In this paper, we present the overall system design and performance, assuming an ideal cold cube and semi-transparent hot...
