The effect of Surface Heterogeneity on the Temperature-Humidity Correlation and the Relative Transport Efficiency [PDF]

, 2008
We derive a conceptual model of the flow over heterogeneous terrain consisting of patches with contrasting Bowen ratios. Upward moving eddies are assumed to carry heterogeneous properties, whereas downward moving eddies carry homogeneous properties. This

Relative efficiency of Argentinean airports [PDF]

The main objectives of this paper are to measure the relative efficiency of Argentinean airports, and to infer possible regulatory consequences of the results. We pay attention to regional differences that could help the regulator in its task.

The maximum efficiency of nano heat engines depends on more than temperature [PDF]

, 2019
Sadi Carnot's theorem regarding the maximum efficiency of heat engines is considered to be of fundamental importance in thermodynamics. This theorem famously states that the maximum efficiency depends only on the temperature of the heat baths used by the

Low Temperature Drying With Air Dehumidified by Zeolite for Food Products: Energy Efficiency Aspect Analysis [PDF]

, 2011
Developments in low temperature drying of food products are still an interesting issue; especially with respect to the energy efficiency. This research studies the energy efficiency that can be achieved by a dryer using air which is dehumidified by ...

Energy-efficient coding with discrete stochastic events [PDF]

, 2002
We investigate the energy efficiency of signaling mechanisms that transfer information by means of discrete stochastic events, such as the opening or closing of an ion channel.

Assessment of the inactive dead layer thickness of old high-purity germanium detector: A study by Monte Carlo simulations and experimental verification

Radiation Protection and Environment, 2017
High-purity germanium (HPGe) detectors are commonly used for high-resolution gamma spectrometry. A HPGe detector considered for this study was in continuous operation for the past 15 years in our laboratory.

Note on Relative Efficiency of Tests

The Annals of Mathematical Statistics, 1958
This note is concerned with possible definitions of relative efficiency for two sequences of tests of the same hypothesis. For two examples of one kind of definition, relative efficiencies of the Student test and sign test against normal alternatives are calculated for fixed sample size and asymptotically.

The relative efficiency of public and private sector water [PDF]

, 2005
A range of empirical evidence now shows that there is no systematic significant difference between public and private operators in terms of efficiency or other performance measures.
