Determining the number of psychiatric beds needed

Determining the number of beds in the postanesthesia care unit: a computer simulation flow approach.

UNLABELLED Designing a new operating room (OR) suite is a difficult process owing to the number of caregivers involved and because decision-making managers try to minimize the direct and indirect costs of operating the OR suite. In this study, we devised a computer simulation flow model to calculate, first, the minimum number of beds required in the postanesthesia care unit (PACU). In a second ...

Determining the number of replicates needed to detect differentially expressed genes in a microarray experiment

The practice of identifying differentially expressed genes by comparing the observed differential expressions to variability expected due to random fluctuations in observed differential expression is becoming predominant in the analyses of DNA array data. In order to estimate the total variability in the system, more than one experimental replicate is needed. Generally, the probability of detec...

Determining the Number of Games Needed to Guarantee an NHL Playoff Spot

Many sports fans invest a great deal of time into watching and analyzing the performance of their favourite team. However, the tools at their disposal are primarily heuristic or based on folk wisdom. This paper provides a concrete mechanism for calculating the minimum number of points needed to guarantee a playoff spot in the National Hockey League (NHL). Along with determining how many games n...

The Number of Reidemeister Moves Needed for Unknotting the Number of Reidemeister Moves Needed for Unknotting

There is a positive constant c 1 such that for any diagram D representing the unknot, there is a sequence of at most 2 c 1 n Reidemeister moves that will convert it to a trivial knot diagram, where n is the number of crossings in D. A similar result holds for elementary moves on a polyg-onal knot K embedded in the 1-skeleton of the interior of a compact, orientable, triangulated PL 3-manifold M...
