Carvil, PA, Attias, J, Evetts, SN, Waldie, JM, and Green, DA. The effect of the gravity loading countermeasure skinsuit upon movement and strength. J Strength Cond Res 31(1): 154-161, 2017-Effective countermeasures against musculoskeletal deconditioning induced by microgravity and disuse are required. A simple alternative to provision of artificial gravity by centrifugation is compressive axial...

Infrared temperature-sensing techniques have the major advantages of virtually no interference of the sensor with the sensed phenomenon and fast inherent response. On the other hand, infrared temperature sensing, as a superficial measurement technique, does not indicate the specimen’s core temperatures, and hence a complementary thermal analysis is required. A thermal analysis of surface temper...

Both experimental tests and numerical simulations have been performed in this study to analyze the influence of long-term immersion (over 500 days) on hygro-elastic hygro-viscoelastic behaviour epoxy resin samples. First, a diffusive swelling campaign was carried out with water at 25 °C 60 °C. Various also undertaken different stages ageing highlight quantify diffusion elastic viscoelastic prop...

This paper is concerned with analysis for the strengthening effect of carbon fiber-reinforced polymer (CFRP) on steel columns under cyclic lateral loading in thermal environment. Based on the finite element theory of thermo-elastic problem and steel structure stability theory, the hysteretic behavior of axial compression steel columns was studied by using Ansys software. The main variables inve...

Transformer is one of the most important components of power system, which determining its reliability is very important. To evaluate transformer overall reliability, in addition to probability of failures occur due to chance events, the probability of failures owing to aging should be taken into account. To determine transformer reliability in aging area, estimating its remaining life is of gr...

Thermal conductivity of graphite bipolar plates (BPP) decreases with temperature. Thermal Contact resistance (TCR) between BPP and GDLs decreases with compression. GDL-BPP TCR increases with MPL and PTFE, regardless of the PTFE loading. High PTFE loading, MPL, and BPP outof-flatness increase the TCR dramatically. The graphite BPP-GDL TCR is a dominant resistance in a BPP-GDL assembly. a r t i c...

In the present work, we report measurements of the effective thermal conductivity of dispersions of single-walled carbon nanotube (SWNT) suspensions in ethylene glycol. The SWNTs were synthesized using the alcohol catalytic chemical vapour deposition method. Resonant Raman spectroscopy was employed to estimate the diameter distribution of the SWNTs based on the frequencies of the radial breathi...

Flow effects on the thermal loading in different optofluidic systems (optical trap and various microfluidic channels) have been systematically explored by using dye-based ratiometric luminescence thermometry. Thermal images obtained by fluorescence microscopy demonstrate that the flow rate plays a key role in determining both the magnitude of the laser-induced temperature increment and its spat...
