ef·fi·cien·cy

(e-fish'en-sē),
1. The production of the desired effects or results with minimum waste of time, money, effort, or skill.
2. A measure of effectiveness; specifically, the useful work output divided by the energy input.

efficiency

Lab medicine The relative ability of a test to detect a disease, while maintaining the rate of false positive results to a minimum; the efficiency of a test is defined as the number of true positives and true negatives multiplied by one hundred, divided by the sum of true positives, true negatives, false positives and false negatives. Cf Four cell diagnostic matrix.

Patient discussion about efficiency

Q. Is electric shock efficient for ocd? Is it dangerous? My husband has OCD for 15 years now. He was also diagnosed with mania-depressia. He takes so many medications and nothing really helps. We were offered to try electric shock and I'm scared. Is it dangerous? What are the chances of this method to work for him?

A. Electroconvulsive therapy (ECT) is indeed considered effective for OCD, although it's not the first line of treatment. It does have its risks, including memory loss, disorientation and sort of confusion. There is also a change in the activity of the heart but it's rarely significant.

Generally it can be said that it's not an absolutely safe treatment, but it may help, especially if other drugs don't help.

This could be considered to be a good trend for improving both technical and cost efficiencies.
The popularity of DEA is due to its ability to measure relative efficiencies of multiple-input and multiple-output of DMUs without including prior weights for the inputs and outputs.
In first step, it measures the bias-corrected efficiency scores while DEA measures the biased efficiencies and it exaggerates the efficiency scores.
However, the aforementioned different types of efficiencies and trade-offs associated with their interplay complicate derivation of a common efficiency standard for assessing consumer welfare.

Ends/MS/FS Muscat, Sep 18 (ONA) The Ministry of Education will organize next week a three-day National Symposium under the theme ' Education and 21st Century Efficiencies. A number of local and foreign experts and educators takes part in the symposium, which comes in response to the Royal directives of His Majesty Sultan Qaboos Bin Said, which urge for more interest in the quality education outputs, the importance of linking education outputs with Labour market requirements through revising the education policies and programs.
They applied Data Envelopment Analysis (DEA) to measure and compare the cost, revenue and profit efficiencies. The conclusion they made is that there is no significant difference between Islamic versus conventional banks on the basis of overall efficiency.
Due to the translation invariance characteristic of DEA, values transformation will not affect the relative efficiencies of the DMUs.
Four efficiencies come to mind relative to any wind machine, or any other type of so-called renewable energy generator, and there may be others:
The efficiencies obtained are precise values, considered as certainty cases.
Guidance should stress the importance of looking for efficiencies across as well as within components and programs and maintaining or improving key dimensions of performance such as effectiveness, quality, or customer satisfaction, while also striving for efficiency gains.
