A mass-conserving and multi-tracer efficient transport scheme in the online integrated Enviro-HIRLAM model
A mass-conserving multi-tracer effi cient transport scheme
2014/12/12
In this paper a new advection scheme for the
online coupled chemical–weather prediction model EnviroHIRLAM is presented.
The methanol molecule CH3OH has a complex microwave spectrum with a large number of very strong lines. This spectrum includes purely rotational transitions as well as transitions with contributions of...
Sequential Assimilation of Tracer Test Data by Ensemble Kalman Filter for Fracture Identification
Ensemble Kalman filter Sequential data assimilation Tracer test Fracture CVBEM
2010/9/8
Application of the ensemble Kalman filter (EnKF) to reservoir characterization has the limitation that the observed watercut data cannot be reflected for tuning model variables in some time intervals....
Atmospheric Transport Modeling with 3D Lagrangian Dispersion Codes Compared with SF6 Tracer Experiments at Regional Scale
Atmospheric Transport 3D Lagrangian Dispersion Codes
2009/9/3
The results of four gas tracer experiments of atmospheric dispersion on a regional scale are used for the benchmarking of two atmospheric dispersion modeling codes, MINERVE-SPRAY (CEA), and NOSTRADAMU...
Sulfidation State and Sulfur Behavior on Mo-based HDS Catalysts Supported on TiO2 Using 35S Tracer Methods
Sulfidation state Hydrodesulfurization High surface titania Molybdenum catalyst
2009/8/4
A 35S radioisotope pulse tracer method using 35S-labeled H2S was used to investigate the sulfidation state of Mo-based catalysts supported on TiO2. Despite the coverage of Mo species on the TiO2 supp...
Effects of Well Arrangement on Characterization of Discrete Fracture Systems by Inverse Analysis of Tracer Tests
Tracer test Fracture system Inverse analysis Boundary element method
2009/7/28
Of interest in this study are the effects of well arrangement on the characterization of distributed multiple fractures through tracer tests. Numerical experiments with 1000 fracture-system realizati...
Investigation of Sulfur Behavior on Mo-based Hydrodesulfurization Catalysts Supported on High Surface Area TiO2 by 35S Radioisotope Tracer Method
Hydrodesulfurization High surface area titania Molybdenum catalyst
2009/7/27
Mo catalysts were prepared by impregnation of titania synthesized by the pH swing method which provides a TiO2 carrier with a high specific surface area (134 m2·g−1) and excellent mechanical pr...
Identification of Fracture Properties by Inverse Analysis of Tracer Tests Using Genetic Algorithms
Fracture Tracer test Inverse analysis CVBEM Genetic algorithm
2009/7/24
Any fractures present in a porous medium have a greater influence on the flow of fluid than the porosity of the bulk material because the fractures are much more permeable. The tracer test, one metho...
V类化合物的通式为: RR′OPOSCH_2CH_2NR_2(R=C_1～C_3,R′=C_1～C_10,R″C_1～C_3),V类化合物EI质谱图最特征峰是带有胺基端的两种碎片离子峰,在其他部位发生断裂产生的峰个数少、强度低。具有相同胺基端的不同V类化合物EI质谱图相同,因此难于准确确定 其结构。而V类化合物的红外光谱图具有明显的特征,可以准确确定其结构。本文主要介绍了我们使用Bio-Rad公司...

A time series of environmental tracer data from deep meromictic Lake Lugano, Switzerland
A time series of environmental tracer data deep meromictic Lake Lugano Switzerland
2014/4/22
An 11-yr (1990-2001) time series of tritium-helium-3 (3H-3He) apparent water ages as well as one sulfur hexafluoride (SF6) profile were used to study the development of the vertical mixing dynamics of...
Design of an Indegenised Negative Resistance Characteristics Curve Tracer
Curve tracer Negative resistance V-I characteristics plotter Negative resistance phenomenon Tracing circuitry
2010/12/8
“Negative Resistance” exhibited by a device during some portion of its V-I characteristics produces jump phenomenon, hysteresis and oscillation in the tracing circuitry. A method is presented to overc...
