Semi–Empirical Model of the Simulation of Traffic Pollution Dispersion Near Roadways

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2011
A semi-empirical statistical model based on physical processes intended for simulation of traffic pollution dispersion near roadways is applied. The pollution source is a road and transport, which in this model is simulated as an undeviating cut-off ...

Electron density in the F1 layer over Norilsk in 2007–2014

open access: yesSolar-Terrestrial Physics, 2019
We report the results of the analysis of annual variations in daily electron density (N) for various solar activity conditions — minimum, rise, and maximum (2007–2014) — obtained from digisonde measurements at the ionospheric station Norilsk (69.4° N, 88.

Semi-automatic distribution pattern modeling of web service compositions using semantics [PDF]

open access: yes, 2006
Enterprise systems are frequently built by combining a number of discrete Web services together, a process termed composition. There are a number of architectural configurations or distribution patterns, which express how a composed system is to be ...

TwO Parameters Semi Empirical Model (TOPSEM): Galaxy Evolution and Bulge/Disk Dicothomy from Two-stage Halo Accretion

open access: yesThe Astrophysical Journal, 2023
In recent years, increasing attention has been devoted to semi-empirical, data-driven models to tackle some aspects of the complex and still largely debated topic of galaxy formation and evolution. We here present a new semi-empirical model whose marking

Semi-empirical model of the spatiotemporal surface temperature distribution on the plain part of Ukraine

open access: yesГеофизический журнал, 2023
The spatial variation of temperature is found to depend linearly on climate continentality, morphology of the relief, the position of the site with respect to seas, in addition to the usual elevation, latitude and longitude predictors.

Soil moisture retrieval model by using RISAT-1, C-band data in tropical dry and sub-humid zone of Bankura district of India

open access: yesEgyptian Journal of Remote Sensing and Space Sciences, 2015
Soils play a key role in various hydrological and meteorological applications. The objective of this paper is to analyze the spatial variability of very high resolution (3.3 m) RISAT-1 (5.35 GHz) data with surface soil parameters to produce soil moisture
