Stratigraphically consistent autointerpretation of borehole data
Many techniques exist for computer-aided interpretation of geological, geotechnical, and resource quality parameters from downhole geophysical data...
Borehole geophysical techniques to define stratigraphy, alteration and aquifers in basalt
The value of several wireline tools is critiqued. Natural gamma logs have limited utility in basalt sequences unless anomalously high-potassium ...
Reconstruction of 3D building models from aerial images and maps
Automatic 3D building reconstruction has becoming increasingly important for a number of applications. The reconstruction of buildings ...
Detecting building changes from multitemporal aerial stereopairs
Our goal is to detect changes in an aerial scene by comparing grey scale stereopairs taken several years apart in order to update a ...
Graph-supported verification of road databases
The verification of existing data is an important task in order to ensure a high level of data quality, such as is needed in geographic ...
Object extraction and revision by image analysis using existing geodata and knowledge: current status and steps towards operational systems
focuses mainly on extraction of important topographic objects, like buildings and roads, that have received much attention the last decade...
The ways ahead for rock engineering design methodologies
discuss the future of rock engineering design methodologies within the framework of the eight current and potential basic design ...
A decay function model for the integrity loss of rock when subjected to recurrent cycles of freezing–thawing and heating–cooling
Rocks are used in engineering works as monument or building stone and as architectural covering stone. As a result, they can be subjected ...
An estimation method for cover pressure re-establishment distance and pressure distribution in the goaf of longwall coal mines
Measurement of deformations and stresses in the goaf of longwall panels is difficult due to the inaccessibility of the waste area. This ...
Molecular modeling and rational design of flotation reagents
A scientific design methodology based on molecular modeling tools available today is presented for arriving at the most suitable reagent ...
Rational polymer design for solid–liquid separations in mineral processing applications
Designing polymers for improving solid–liquid and solid–solid separations in mineral processing requires ...
Modeling flocculation of colloidal mineral suspensions using population balances
Flocculation as well as dispersion of mineral suspensions has become increasingly important in mineral processing as we have to deal ...
Flocculation and flotation characteristics of fine hematite with sodium oleate
Flocculation and flotation characteristics of fine hematite with sodium oleate have been investigated through electrophoretic mobility...
