Numerical study of concrete-filled steel composite (CFSC) stub columns with steel stiffeners is presented in this paper. The behaviour of the columns is examined by the use of the finite element ...

Excel's grid feels like an endless canvas until you hit the boundaries of row 1,048,576 or column XFD. These limits aren't random—they're digital walls shaped by history, hardware, and binary logic.

Adequate wideband characterization of printed circuit board (PCB) dielectric substrates is critical nowadays in high-speed signal and power integrity design. Traditional approximations using frequency ...
