Suh as, Gatmiri and Jabbari (2005a, 2005b) replaced some coefficients dependent on the saturation degree by saturation degree values in different constant suction areas, and then obtained the corresponding two and three-dimensional semi-analytical solutions for time-domain Green's functions for ...
16 pointed out that the analysis method based on lame formula was wrong, and proposed to study hydraulic fracturing from the mechanism of seepage force, but only the state of stable seepage was considered. Wang et al.18,19 developed a one-dimensional unsteady seepage model, derived an ...
Figure 2. Sketch of the vertical extension of the various layers over rough surfaces and their variation with the nondimensional quantities z/zh and zi/zh. Here, z denotes the (physical) height, zi refers to the boundary layer height, and zh is the (average) height of roughness elements....
The feature space in machine learning models is often non-convex and high-dimensional, making it challenging to find the optimal combination of features manually. ChoA is designed to handle non-convex optimization problems, making it well-suited for feature selection and hyperparameter optimization. ...
One-dimensional test problems are used to introduce and validate the MPCE, but the method is also applicable in multidimensional problems.doi:10.1080/10407790903244360Ashrafizadeh, A.Rezvani, M.Bakhtiari, B.Taylor & Francis GroupNumerical Heat Transfer Part B Fundamentals...

Then a two-dimensional weighted Dirac delta function \(\omega(t)\delta_{\Gamma}\) with the support on Γ is defined by $$ \bigl\langle \omega(s)\delta_{s},\varphi\bigl(x(s),t(s) \bigr)\bigr\rangle = \int_{a}^{b} \omega(s)\varphi\bigl(x(s),t(s)\bigr) \,ds ...
Density is a dimensional property; therefore, when comparing the densities of two substances, the units must be taken into consideration. For this reason, a more convenient, dimensionless quantity called the specific gravity is often used to compare densities.Specific gravityis defined as the ratio ...
The behavior of the corresponding schemes is examined in detail in light of one-dimensional model problems, based on finite-difference or spectral-element discretizations.Olivier Le Maı̂tre and Julia Levin and Mohamed Iskandarani and Omar M. Knio...
Consequently, most developments in this field are based on dimensional considerations aided by data obtained from experimental measurements. Great care must be exercised, however, when using these methods outside the limits of the experimental work. Good accounts of idealised theoretical developments in ...
