Flag

A pattern reflecting price fluctuations within a narrow range, generating a rectangular area on a graph both prior to and after sharp rises or declines.

Flag

In technical analysis, a situation on a chart in which a security's price undergoes a steep rise or fall, then trades within a narrow price range. When a steep rise proceeds the narrow trading, it looks somewhat like a flag raised on a pole. Many analysts believe that when a flag occurs, the narrow trading is only temporary and will soon be followed by another steep rise or fall. That is, a rise will follow a rise and a fall will follow a fall.

In the Mutex example, B = 14 implies no grouping; that is, the 14 automata are kept separate.
The explicit proposition layers can aid mutex propagation, allowing TPSys to compute more mutexes than Temporal GraphPlan (Garrido, Onaindia, and Barber 2001).
After computing I(a, b) = Pr(a [and] b) / Pr(a)P(b), having I(a, b) = 0 means that a and b are mutex, having I(a, b) = 1 means that a and b are independent, having 0 < I(a, b) < 1 means that a and b negatively interact, and having 1 < I(a, b) means that a and b positively interact.
If a process holds a mutex channel of type [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], then it has the capability to send/receive a value along the channel (the send operation is allowed only once), but it only has an obligation to send a value: it need not receive a value from the channel.
As another example, suppose [t.sub.x] is the time tag of a mutex channel x and [t.sub.y] is the time tag of another channel y, then
The following two invariants describe the bubble of mutual exclusion on entry to rmeld and rxmeld (lines 1 and 8 in Figure 4): First, the current process has exclusive use of the pointer variable referenced by q, so mutex (the associated semaphore) is zero.
First, two action instances at level i are mutex if either (1) the effect of one action is the negation of another action's effect (inconsistent effects), (2) one action deletes the precondition of another (interference), or (3) the actions have preconditions that are mutually exclusive at level i - 1 (competing needs).
A traditional approach to an assurance of the shared resources consistency is a usage of mutexes [2].
Older modelers programmed their thread-safety after the fact by using mutexes, severely limiting the speed at which the computer can utilize multiprocessor capabilities.
* crTRi[0:3][31:0] memorizes the events validated or inhibited by the wait nHSE instruction, one bit for each of the seven events (from right to left, the events generated by the timer, by the watchdog, by deadline 1 and deadline 2, by interrupts, mutexes and synchronizing events, are validated (1) or inhibited (0)).
