APPROPRIATENESS OF BURNING RATE MEASURING TECHNIQUE WITH THE MEASURING CONDITIONS AND REQUESTED DATA

Measuring the appropriateness of hospital use.

DANS CE NUMÉRO (PAGE 889), CAROLYN DECOSTER ET DES COLLÈGUES présentent un compte rendu sur la pertinence de l’utilisation des hôpitaux au Manitoba par les patients qui ont fait l’objet d’un diagnostic médical. Ils concluent qu’en 1993–94, 51 % des admissions effectuées dans les hôpitaux visés par l’étude étaient inappropriées et que 67 % des jours d’hospitalisation étaient inutiles. Ils n’ont ...

Context-Dependent Data Envelopment Analysis-Measuring Attractiveness and Progress with Interval Data

Data envelopment analysis (DEA) is a method for recognizing the efficient frontier of decision making units (DMUs).This paper presents a Context-dependent DEA which uses the interval inputs and outputs. Context-dependent approach with interval inputs and outputs can consider a set of DMUs against the special context. Each context shows an efficient frontier including DMUs in particular l...

Impact of Measuring Devices and Data Analysis on the Determination of Gas Membrane Properties

The time-lag method, using a gas permeation experiment, is currently the most popular method for determining the membrane properties: diffusivity coefcient and permeability coefcient, and from which the solubility coefcient can be calculated. In this investigation, the impact of systematic, random (noise), resolution and extrapolation errors associated with gas permeatio...

Technique of measuring rapid water penetration rate into tablets.

An accurate method for measuring the fast uptake of water into tablets was established. The method involved the use of a video camera to monitor the flow of liquid in the capillary tube of the water penetration apparatus. Measurements of water uptake could be made in as short an interval as 0.04 s from 0 s. The liquid penetration profiles show that there are three linear portions of the double ...
