Lower complexity bounds of first-order methods for convex-concave bilinear saddle-point problems

Mathematical programming, 2018
On solving a convex-concave bilinear saddle-point problem (SPP), there have been many works studying the complexity results of first-order methods. These results are all about upper complexity bounds, which can determine at most how many iterations would

Heat transfer characteristics of concave and convex curved vortex generators in the channel of plate heat exchanger under laminar flow

International journal of thermal sciences, 2019
The geometric shape of vortex generator (VG) is an important contributory factor to heat transfer enhancement. In this paper, concave and convex curved delta winglet VGs in a channel of plate heat exchanger under laminar flow are studied and compared ...

Generating a Type of Concave Cupolae of Fourth Sort

2013
The paper discusses the generation of a specific group of polyhedra, Concave Cupolae of Fourth Sort (CC IV) with regular polygonal bases, using constructive and analytical procedures. Beside determination of the parameters of these polyhedra, the paper deals with their visualization, by the application of graphical software MATLAB.
