The remaining difficult part of the Skolem problem is determining whether the finite set of non-repeating zeros is empty or not. [1] Partial solutions to the Skolem problem are known, covering the special case of the problem for recurrences of degree at most four. However, these solutions do not apply to recurrences of degree five or more. [1 ...
The International Blinking Pattern Interpretation (IBPI) is an internal computer hardware standard. It defines two items: It defines two items: How SGPIO is interpreted into states for drives or slots on a backplane.
The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
In software design, the blinking twelve problem [1] is when features in software or computer systems are rendered unusable to most users by the complexity of the interface to them. The usage emanates from the 'clock' feature provided on many VCRs manufactured in the late 1980s or early 1990s. The clock could be set by using a combination of ...
New York Times columnist Nicholas Kristof admitted that the West Coast's "permissive" policies regarding drug usage and combatting addiction "almost killed" many addicts.
In celestial mechanics, Lambert's problem is concerned with the determination of an orbit from two position vectors and the time of flight, posed in the 18th century by Johann Heinrich Lambert and formally solved with mathematical proof by Joseph-Louis Lagrange. It has important applications in the areas of rendezvous, targeting, guidance, and ...
The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
Diophantine problems have fewer equations than unknowns and involve finding integers that solve simultaneously all equations. Because such systems of equations define algebraic curves , algebraic surfaces , or, more generally, algebraic sets , their study is a part of algebraic geometry that is called Diophantine geometry .
