The term efficiency can be defined as the ability to achieve an end goal with little to no waste, effort, or energy. Being efficient means you can achieve your results by putting the resources you have in the best way possible. Put simply, something is efficient if nothing is wasted and ...
The degree of efficiency of any two methods is defined as the ratio of their mean square errors in determining the true mean of a reference method. This quantity can be described by the ratio of the upper bounds for the probabilities of an error by the two methods. The degree of ...
Hypersonics is defined, herein and conventionally, as flight at Mach numbers of 6 or greater. Historically, hypersonic vehicles have been rocket boosted/propelled with well-known performance limits in terms of specific impulse. Contempor... DM Bushnell - Springer Netherlands 被引量: 17发表: 1994年...
To determine the efficiency of a boiler, a system boundary must be defined and the energy flows that cross the boundary need to be resolved. System boundaries should be chosen so that it is possible to define all energy and mass flows in and out with sufficient accuracy. In practice, many ...
In this letter, relative diffraction efficiency is defined as the power of the +1 grating order divided by the power of transmitted light, while diffraction efficiency is the same but divided by the power of incident light following the terminologies used in ref.42. For metalenses, relative and...
From this context, based on the previous literature and data availability, the output variables can be defined as follows: (1) Total loans (𝑌1)(Y1), which mainly include loans (long-term, medium and short-term) and invoices (commercial and discounted). Total loans do not include loan ...
More specifically, we use the measures that originate from the seminal work on technical efficiency by Farrell (1957), where technical efficiency is defined as the Results The farmers at the irrigation schemes studied mainly grow vegetable crops using simple irrigation techniques (see Table 2). ...
Based on the above model setting, the economic efficiency of area i in year t could be defined as: $${\mathrm{TE}}_{it} = \frac{{Y_{it}}}{{X_{it} \cdot \beta _j + v_{it}}}$$ (3) Input-output variable for production function We adopt a logarithmic C-D production ...
为了最小化CPU和内存的使用,Columbia采用了几种工程技术来提高效率。这些技术包括使用快速哈希函数来消除重复表达式,将逻辑表达式和物理表达式分离在一个组中,使用小型和紧凑的数据结构,使用高效的算法来优化组和输入,以及处理强制规则的高效方式。 Columbia 提供的一个重要技术是组剪枝,它可以显著减少搜索空间而不影响计划...
The sensitivity can be defined as the probability a true positive sample tests positive. For our situation it will be equal to the probability that any sample tests positive: $$P\left(pos\;test\right)=P\left(pos\;test|Cq\ge cut\;off\right)\cdot P\left(Cq\ge cut\;off\right)+P\left...
