Continuous vortex sheet approximation by panel method. Roll-up of a vortex sheet due to an initial sinusoidal perturbation. Note that the integral in the above equation is a Cauchy principal value integral. The initial condition for a flat vortex sheet with constant strength is (,) =. The flat vortex sheet is an equilibrium solution.
Any code that runs on i586 but does not use floating point instructions will run on these models. Any i586 code will run on Vortex86DX and later. Some Linux kernels (by build-time option) emulate the FPU on any CPU that is missing one, so a program that uses i586-level floating point instructions will work on any Vortex86 family CPU under such ...
In mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card. One or more time cards could serve as a timesheet or
In electronics, point-to-point construction is a non-automated technique for constructing circuits which was widely used before the use of printed circuit boards (PCBs) and automated assembly gradually became widespread following their introduction in the 1950s.

Police received a report at 3:45 a.m. local time Saturday about an explosion at the Drents Museum in Assen. Upon arrival, officers found the museum damaged and the gold masterpieces gone.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
Animation of vortex street created by a cylindrical object; the flow on opposite sides of the object is given different colors, showing that the vortices are shed from alternating sides of the object A look at the Kármán vortex street effect from ground level, as air flows quickly from the Pacific Ocean eastward over Mojave Desert mountains.
