High resolution stepper and servo motor linear actuators. Image Credit: PI. For tasks requiring sub-micrometer precision — such as alignment, adjustment, or fine positioning — PI’s M-235, L-220, and M ...

It was a nice try, but incorrect. A few others came up with 42.5 dogs as the answer, with one woman explaining her method as follows: "49-36=13. 13/2=6.5. 36+6.5=42.5.

Goto Joji, an expert in mathematics education, emphasizes the need for university-level mathematics education to develop ...

This paper discusses a class of linear programming problems with interval coefficients in both the objective functions and constraints. The noninferior solutions to such problems are defined based on ...

These seven words, “The pitches are not great here, honestly,” have since become a rallying point for wider criticism about the standard of facilities at this year’s Club World Cup. And as the U.S.

Abstract: While linear programming (LP) decoding provides more flexibility for finite-length performance analysis than iterative message-passing (IMP) decoding, it is computationally more complex to ...

Disgraced former New York Rep. Jamaal Bowman dubiously claimed on Wednesday that black people suffer worse health outcomes because of other people’s usage of the n-word. Bowman […] ...

PaPILO, a C++14-based software package, provides parallel presolve routines for (mixed integer) linear programming problems. The routines are implemented using templates which allows switching to ...

This project is aimed at implementing nonlinear programming algorithms as the (un-)constrained minimization problems with the focus on their numerical expression using various programming languages.

Self-powered catalytic micromotors that swim through a fluid by harvesting energy from their environment have received increasing attention because of their potential applications in nanomachinery, ...

Compared with other problem book, this one has few new basic features. They include problems dealing with polynomial matrices (Sec. 13), linear transformations of affine and metric spaces (Secs. 18 ...
