The purpose of this study was to evaluate the effects of using the critical velocity (CV) concept to prescribe two separate high-intensity interval training (HIT) exercise programs aimed at enhancing CV and load carriage performance. Twenty young adult participants (male =15, female =5) underwent a 4-week training period where they exercised 2 d·wk...

In this thesis, fires in road tunnels with longitudinal and transverse ventilation systems are investigated numerically and experimentally. The fire smoke is simulated as a buoyant plume obtained by injecting a mixture of air and helium into ambient air. With this simplified representation, the radiation and the heat losses at the walls are not tak...

A 1/3 scaled tunnel model was built to explore the effect of fire source elevation on fire and smoke behavior, and especially the critical velocity, in a tunnel with longitudinal ventilation. An experimental campaign has been carried out with a series of tests in 9 configurations, varying the fire size, ventilation velocity and fire elevation. Resu...

The coal mining mode of paste-like slurry fill shows the connotation and characteristics of green mining both in the resource recycle and waste reuse. Test by intelligent torque sensor, fitted by the ORIGIN software, the following relationships were obtained: (1) rheological parameters versus slurry mass fraction, (2) rheological parameters versus ...

A fluid-conveying cantilever pipe is likely to lose stability by flutter when the fluid is conveyed at certain critical velocity. In the present work, in order to avoid instability and reduce the possibility of unbounded vibrations, parametric studies and numerical investigations were carried out to fine-tune the fluid-conveying cantilever pipe by ...

In successive alkalinity-producing systems (SAPS), the limestone tends to get coated with precipitates, reducing the permeability of the SAPS, the mine water treatment efficiency, and the service life of the SAPS. Further study of the precipitates are required to improve the design of flushing systems. In this study, the growth characteristics, par...

The critical flutter velocity is an essential factor in aeronautic design because it caracterises the flight envelope outside which the aircraft risks to be destroyed. The goal of this thesis is the study of the impact of uncertainties of aleatory and epistemic origin on the linear stability limit of idealised aeroelastic configurations. First, a d...

On May 10th, 2012, 41 sinkholes collapsed the southern suburbs of Liuzhou, Guangxi Province, China, damaging 143 houses, eight factories buildings, and three commercial buildings. Lei (2013) revealed that groundwater dynamics, contributed to by the daily rainfall of 169.7 mm, led to soil particles running off (seepage erosion) resulting in the sink...

We investigate the stability and critical velocity of a weakly interacting Bose gas flowing in a random potential. By applying the Bogoliubov theory to a disordered Bose system with a steady flow, the condensate density and the superfluid density are determined as functions of the disorder strength, flow velocity, and temperature. The critical velo...
