A problem statement is a description of an issue to be addressed, or a condition to be improved upon. It identifies the gap between the current problem and goal. The first condition of solving a problem is understanding the problem, which can be done by way of a problem statement. [1]
The Na 2 SiH 2 dissolves in the mercury to generate the diradical SiH 2, which then forms the final products. [3] Polysilicon hydrides may also be produced by the dehalogenation of polysilicon halides. An illustrative reaction is the debromination of HSiBr 3 with Mg in ether: [4] HSiBr 3 + 3/2 Mg → 1/x (SiH) x + 3/2 MgBr 2
The Short Integer Solution (SIS) problem is an average case problem that is used in lattice-based cryptography constructions. Lattice-based cryptography began in 1996 from a seminal work by Ajtai [ 1 ] who presented a family of one-way functions based on the SIS problem.
Mira variable stars of type M or S may have emission lines of SiH. In even cooler brown dwarfs and planets, SiH is not found, but instead silicon takes form as silicon monoxide at low pressures, and SiH 4 at high pressures. Minute amounts of SiH as a transient species may be found in these bodies as SiO and SiH 4 react with water. [4]
In computer science, the dining philosophers problem is an example problem often used in concurrent algorithm design to illustrate synchronization issues and techniques for resolving them. It was originally formulated in 1965 by Edsger Dijkstra as a student exam exercise, presented in terms of computers competing for access to tape drive ...
hexasilane Si 6 H 14 or H 3 Si−SiH 2 −SiH 2 −SiH 2 −SiH 2 −SiH 3, 6 silicon atoms and 14 hydrogen atoms, analogous to hexane; Silanes are named by adding the suffix-silane to the appropriate numerical multiplier prefix. Hence, disilane, Si 2 H 6; trisilane Si 3 H 8; tetrasilane Si 4 H 10; pentasilane Si 5 H 12; etc.
The suspects in the killing of a Border Patrol agent had been associating with multiple people suspected in a series of violent crimes across the U.S., prosecutors say.
The silanide ion has an effective ionic radius of 2.26 Å. In salts at room temperature the ion's orientation is not stable, and it rotates. But at lower temperatures (under 200K) silanide becomes fixed in orientation. [7]
