3D stability analysis method of concave slope based on the Bishop method
International Journal of Mining Science and Technology, 2017 In order to study the stability control mechanism of a concave slope with circular landslide, and remove the influence of differences in shape on slope stability, the limit analysis method of a simplified Bishop method was employed.

The Piecewise Concave Function
Management Science, 1967 An important function which is neither concave nor convex often arises in production and inventory models. This function is herein called piecewise concave and can be considered to be a generalization of the concave function. Essentially it is the maximum of a collection of concave functions.

BIT Numerical Mathematics, 2000 Interval arithmetic provides various techniques to construct upper and lower bounds of function values \(f(x)\), \(x\in X\) where \(X\) is a \(n\)-dimensional box. Well-known means for obtaining these bounds are interval extensions. The bounds, however, can be quite crude.

Experimental and Numerical Investigation of the Heat Transfer of Honeycomb-Structured Tubes
Thermo, 2023 Tube bundle recuperators are generally designed to operate with smooth tubes. Structured tubes can be used to increase the efficiency of recuperators. Compared to smooth tubes, the surface for heat transfer is increased and thus heat transfer is enhanced.

CoRR, 2021 It has been well established that first order optimization methods can converge to the maximal objective value of concave functions and provide constant factor approximation guarantees for (non-convex/non-concave) continuous submodular functions. In this work, we initiate the study of the maximization of functions of the form $F(x) = G(x) +C(x)$ over a

Assessment of Turbulence Models over a Curved Hill Flow with Passive Scalar Transport
Energies, 2022 An incoming canonical spatially developing turbulent boundary layer (SDTBL) over a 2-D curved hill is numerically investigated via the Reynolds-averaged Navier–Stokes (RANS) equations plus two eddy-viscosity models: the K−ω SST (henceforth SST) and the ...
