Abstract: The oxide-scale growth and metal loss kinetics during oxidation in air of 2 1/4 Cr-1 Mo steel were studied at 600, 700, and 800°C for times up to 1000 h, with cylindrical specimens ...

Abstract: The oxidation behavior of 214Cr-1Mo steel was studied at 600, 700 and 800°C for a sequence of times up to 1000 h, using cylindrical specimens of the material, similar to testpieces used ...

Abstract: Equation (10) gives ∑j=1nf(xj)≈1Δx∫0Lf(x) dxwhere f(xj)=mjρALϕi(xj)ϕk(xj)Considering that all disks have the same mass mD, then f(xj)=mDρALϕi(xj)ϕk(xj)Hence, from Eq. (10) (11)∑j=1NDmDρALϕi(xj)ϕk(xj)≈1Δx∫0LmDρALϕi(x)ϕk(x ...

Abstract: In the practice of project management, cost contingencies have the objective of covering probable cost increases (risks) above target estimates. Due to the variable performance nature for a wide range of activities, ...

Abstract: This study introduces a new probabilistic project control concept to assure an acceptable forecast of final project performance, in terms of not exceeding planned budget and schedule risk levels. This concept consists in ...

Abstract: Structures with inertia periodicity present the phenomenon of band gap formation, i.e., the appearance of regions in the frequency spectrum with a higher modal spacing and lower vibration response. Rotating machines can ...

Abstract: Paving geotextiles are becoming increasingly used in highway construction overlays in order to recover cracked asphalt pavements. In antireflective cracking systems, the geosynthetic should have the ability to absorb and ...

Abstract: he focus of this study is the characterization of the diurnal cycle of low-level wind and divergence field (under two different synoptic situations observed during the South American Low-Level Jet Experiment) within the ...

Abstract: rban canopy models (UCMs) are being used as urban-climate prediction tools for different applications including outdoor thermal comfort and building energy consumption. To take advantage of their low computational cost, ...

Abstract: This paper presents an evaluation of the soil-geogrid interaction, conducted to quantify the contributions of passive and interface shear mechanisms to the overall pullout resistance of geogrids. An experimental testing ...
