Results for three hypothetical soils of fine sand, silt, and clay are calculated. It emerges that the inclusion of 3D effects and unsaturated transient flow leads to a smaller active earth pressure coefficient. The 3D effects are mainly influenced by the width-to-height ratio of walls; several...
A coefficient of determination of 89% was obtained using the proposed model. Similarly, the RF technique was used to predict the compressive strength of FA-based alkali-activated concretes, considering their physiochemical qualities, curing conditions, and mixing processes [30]. The results reveal ...
In the validation study, the agreement with experimental wind tunnel results from Jacobs and Clay (1936) was found to be excellent even at relatively high angles of attack of ±8°. Furthermore, the mean and dynamic lift coefficients and the mean drag coefficient were all found to correspond ...
Understanding the thermo-hydro-mechanical (THM) behaviour of clay formations, which are being considered as potential hosts for the disposal of radioactive waste in Europe, is important for the feasibility and the safe disposal of heat-generating radioactive waste in deep geological clayey formations...
Fig. 5: AE-Skin for intelligent cars. AE-Skin mounted on car panels can be used to control audio, wind speed, temperature, seat position and seat angle. In the initial state, the panel surface remains flat. When the driver touches the panel, the integrated sensor captures the pressure of...
the diffusion coefficient of active ingredient increases, which allows it to move through the polymer matrix and be released into the surroundings. During this process, the matrix material is not degraded or eroded, so the packaging material maintains its original shape. The process of swelling-cont...
Basin-scale pressure coefficient contours show that the distribution of MnO is consistent with the pressure coefficients, particularly near wells D12-D13-D15, MA18-AH2, and MA22. This reveals a trend of hydrocarbon migration towards the (N)NE and NW, which is also consistent with the ...
(e.g. at amphoteric ligand sites existing on the edges of clay minerals). The simplest and most common method of estimating RN retardation is by using the solid to liquid distribution coefficientKd. This coefficient describes the partitioning of a RN between the solid and aqueous phases based ...
Data are obtained from a high pressure oedometer (up to 120 MPa) on a sample of COx carefully saturated before running the compression test. As compared with compression curves on stiff clays where a yield stress can be identified in a semi-log plot (5 MPa for Boom clay), the data in ...
even in the case of a spherical carbon having an average particle diameter of 0.3 mm, the MS hardness will not be zero. In this way, the coefficient c of the equation is to adjust deviations from the ideal relationship, and as a result of investigating the relationship between the particle...
