Various image-based velocimetry methods have been developed and increasingly used for surface velocity discharge measurements in rivers. Their evaluation is challenging as situ comparisons are limited affected by uncertainties, synthetic flow images to test laboratory not representative of outdoor applications. A novel method proposed generate river videos with known velocities. The based on op...
Abstract The synthetic control method (SCM) is widely used to evaluate causal effects under quasi-experimental designs. However, SCM suffers from weaknesses that compromise its accuracy, stability and meaningfulness, due the nested optimization problem of covariate relevance counterfactual weights. We propose a decoupling both problems. economic effect government formation deadlock in Spain-201...
This article describes the generation of a detailed two-layered synthetic population households and individuals for French municipalities. Using census data, four reconstruction methods associated with two probabilistic integerization are applied. The paper offers an in-depth description each method through common framework. A comparison these is then carried out on basis various criteria. Resu...
The objective of this study was to compare introgression and synthetic breed strategies for litter size trait improvement in sheep using computer simulation. For this purpose, a trait with heritability of 0.1, consisting of two chromosomes was simulated. On chromosome 1, a single QTL as the major gene was created that accounted for 40% of the total genetic variance. The effect of favorable and ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
