Continuum and Distinct Element Numerical Modeling in Geomechanics 2013 Oct 22, 2013 Oct 24, 2013. The 3rd International FLAC/DEM Symposium was held in Hangzhou, China on October 2224, 2013. This conference provided a venue for engineers, researchers and computer modelers from around the world to meet, discuss, and share their work performing geotechnical numerical analysis with

#0183;#32;This approach, that is, modeling with big data, has been referred to as data modeling, which has focused on representing correlations of data. In detail, such an approach has been classified and studied in each research field in two ways: data mining and machine learning. Figure 1 illustrates how data modeling can be achieved in both ways.

This book is the second edition of the wellknown textbook Modelling Rock Fracturing Processes. The new and extended edition provides the theoretical background of rock fracture mechanics used for modelling of 2D and 3D geomechanics problems and processes.
Numerical modelling has been used to investigate a variety of problems in underground mining and tunnelling: subsidence induced by longwall coal mining; stresses generated when an open stope is filled cemented backfill and the stability of exposures created during subsequent mining of adjacent stopes; the interaction of two tunnels; and the effects of undermining a preexisting tunnel and shaft.
A numerical modeling approach is proposed for predicting the progressive caving behaviour of strata and performance of powered roof support in a given geomining and strata condition.
Since 1995 he has been with CSIRO and focused on issues related to mining geomechanics, mining engineering and mining environment. Dr. Shen is specialised in mining engineering, monitoring instrumentations, numerical modelling, backfill technologies and rock fracture mechanics.
Numerical modeling techniques for ocean circulation are improving rapidly as computer power allows more detailed calculations on finer grids. Recent results for the Canary Current region, representing the nearsurface flow in early September, are shown in Figure model realistically depicts a meandering Azores Current at 35#176;N, which separates into branches entering the Gulf of Cadiz and
#0183;#32;3. Intelligent mining. Digital mining originated with the mine/mining geographic information system as the inevitable outcome of the information age and knowledge economy .The goal of digital mining is to promote the transformation of mine information; support automated mining and intelligent mining; ensure safe, efficient, green, and sustainable mining; and achieve scientific mining.
Traditional topic modelling techniques can be used to successfully extract aspects from text. Like many data science problems, one of the core tasks of the problem is the preprocessing of the data. This has particular effects on sentiment analysis results, where removing specific stop words may impact the identification of negation and therefore the true sentiment expressed.
