Abstract: A novel optimization method is proposed to minimize a convex function subject to bilinear matrix inequality (BMI) constraints. The key idea is to decompose the bilinear mapping as a ...

Are flat pedals better if the platform is convex? Concave? Why not both? While the internet argues about which pedal design provides the best grip and feel, OneUp has been testing prototypes of their ...

By carefully placing nanostructures on a flat surface, researchers have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for ...

By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly ...

Thank you to João Paulo Figueira for his article, "The Concave Hull", describing his Python implementation. In an effort to create an all-in-one library, I have used code available in public forums ...

We obtain a pair of nontrivial solutions for a class of concave-linear-convex type elliptic problems that are either critical or subcritical. The solutions we find are neither local minimizers nor of ...

For any densely defined, lower semi-continuous trace τ on a C*-algebra A with mutually commuting C*-subalgebras A 1, A 2, …A n, and a convex function f of n variables, we give a short proof of the ...

Linköping University researchers achieve a tenfold performance boost in conductive polymer metasurfaces, advancing the field ...

In particular, it is proved that a convex, positive definite function is a Lyapunov function for an LDI if and only if its convex conjugate is a Lyapunov function for the LDIs dual. Examples show how ...
