An improved semi-empirical model for the densification of Antarctic firn [PDF]

The Cryosphere, 2011
A firn densification model is presented that simulates steady-state Antarctic firn density profiles, as well as the temporal evolution of firn density and surface height. The model uses an improved firn densification expression that is tuned to fit depth-

Modeling the Deflection of Circular Membrane Effected by a Cargo Positioned Asymmetrically Relative to the Center

Современные информационные технологии и IT-образование, 2021
The paper considers the problem of deflection of a circular membrane under the action of a load located at some distance from its center. The task consists in obtaining experimental data on the membrane deflection and constructing semi-empirical ...

Semi-empirical model for channel bed evolution due to lateral discharge withdrawal [PDF]

Side weirs and overtopable levees are widely used to increase flood routing along a channel or river. The lateral loss of water reduces the sediment transport capacity leading to the formation of a local sediment deposit close to the overflow.

Semi-empirical analytical modelling of equivalent dynamic shear strength (EDSS) of rock joint

, 2021
A systematic dynamic triaxial series of tests on replicated rough rock joints were carried out, and results clearly highlight the strength attenuation as a function of joint degradation with respect to the number of loading cycles. A novel semi-empirical

A flexible semi-empirical model for estimating ammonia volatilization from field-applied slurry

, 2019
This work describes a semi-empirical dynamic model for predicting ammonia volatilization from field-applied slurry. Total volatilization is the sum of first-order transfer from two pools: a "fast" pool representing slurry in direct contact with the ...

Comprehensive evaluation of semi-empirical models, correction of fitting anomalies, and development of a novel seven-parameter model for silymarin solubility in pure/cosolvent-added supercritical carbon dioxide

Chemical Thermodynamics and Thermal Analysis
This work identifies and corrects model fitting errors in the reported solubility data of silymarin (SM) in pure and cosolvent-modified supercritical carbon dioxide (SCCO2) by Yang et al. [Asian J. Pharm. Sci. 12 (5) (2017): 456-463.].

Measurement of polarization curve and development of a unique semi-empirical model for description of PEMFC and DMFC performances [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2011
In this study, a single polymer electrolyte membrane fuel cell (PEMFC) in H2/ /O2 form with an effective dimension of 5 cm5 cm as well as a single direct methanol fuel cell (DMFC) with a dimension of 10 cm10 cm were fabricated.

A Revisit to the Pretargeting Concept—A Target Conversion

Frontiers in Pharmacology, 2018
Pretargeting is often used as a tumor targeting strategy that provides much higher tumor to non-tumor ratios than direct-targeting using radiolabeled antibody.
