In case of (**Weegy:** b. Positive **User:** In a set of m n equations (m**Weegy:** Please clarify your question. **User:** In a set of m n equations (m**Weegy:** Please clarify your question. **User:** According to penalty rule for artificial variables, the objective coefficient of the artificial variable
represents an appropriate penalty, positive or negative depending on the problem, but the
necessary condition required to hold this is, the value should be:
a.
b. 0
c. 1
d. None of the above
**Weegy:** Can you please be more specific? **User:** An arc in network model is said to be ‘Directed’ if it allows positive flow in one direction and
a. Negative flow in negative direction
b. Zero flow in negative direction
c. Negative flow in perpendicular direction
d. None of the above
**Weegy:** An arc is directed if its having positive flow in one direction only. A network or graph consists of points, and lines connecting pairs of points. The points are called nodes or vertices. The lines are called arcs. [ [ The arcs may have a direction on them, in which case they are called directed arcs. If an arc has no direction, it is often called an edge. If all the arcs in a network are directed, the network is a directed network. If all the arcs are undirected, the network is an undirected network. Two nodes may be connected by a series of arcs. A path is a sequence of distinct arcs (no nodes repeated) connecting the nodes. A directed path from node i to node j is a sequence of arcs, each of whose direction (if any) is towards j. An undirected path may have directed arcs pointed in either direction. ] ] (More)

Explain the usability of stochastic limit .? **Weegy:** Usability:
Usability testing is the process by which the human-computer interaction characteristics of a system are measured, [ [ and weaknesses are identified for correction.

? General appearance ] ] **User:**
WorldcatStochastic Limit Theory **Weegy:** The weak coupling limit for a quantum system, with discrete energy spectrum, coupled to a Bose reservoir with the most general linear interaction is considered: under this limit we have a quantum noise processes substituting for the field. [ We obtain a limiting evolution unitary on the system and noise space which, when reduced to the system's degrees of freedom, provide the master and Langevin equations that are postulated on heuristic grounds by physicists. In addition we give a concrete application of our results by deriving the evolution of an atomic system interacting with the electrodynamic field without recourse to either rotating wave or dipole approximations.
