To teach the discrete element method (DEM) for modelling discontinuum media, using the commercial code UDEC (Universal Distinct Element Code). To teach the use of UDEC in the analysis of underground excavations in fractured rock masses. To discuss case histories of application of UDEC to the design of caverns and tunnels in jointed rock, in reference to cavern support and reinforcement, and groundwater flow.

A discrete numerical model for granular assemblies
Author: CUNDALL, P. A. & STRACK, 0. D. L. | Size: 1.328 MB | Format:PDF | Publisher: Géotechnique | Year: 1979 | pages: 19
The distinct element method is a numerical model capable of describing the mechanical behaviour of assemblies of discs and spheres. The method is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the particles modelled particle by particle. The main features of the distinct element method are described. The method is validated by comparing force vector plots obtained from the computer program BALL with the corresponding plots obtained from a photoelastic analysis. The photoelastic analysis used for the comparison is the one applied to an assembly of discs by De Josselin de Jong and Verruijt (1969). The force vector diagrams
obtained numerically closely resemble those obtained photoelastically. It is concluded from this comparison that the distinct element method and the program BALL are valid tools for research into the behaviour of granular assemblies.

Convert AutoCAD DWG / DXF to ESRI Shape (.shp) -(ArcView, ArcGIS, ArcMap etc.)
- AutoCAD® DXF/DWG to ESRI Shapefile converter –
- Supports all AutoCAD versions up to AutoCAD 2010 -
Size: 12.82 MB
Application developers, if you need output to ESRI shapefile format (and your software already has DXF / DWG output) this is the software module for you, all the hard work is already done!
CAD2Shape is a dwg and dxf converter that converts AutoCAD DWG and DXF files to ESRI SHP (shapefile) files.
Convert AutoCAD DXF/DWG files to ArcView/ESRI shapefile format. It is a stand alone CAD to Shapefile converter, translating all AutoCAD DXF and DWG versions up to and including AutoCAD 2010
CAD2Shape 5.0 converts: AutoCAD DXF/DWG drawing files to ESRI shapefile format files (ArcView, ArcGIS, ArcMap etc.)
Supports all AutoCAD versions up to AutoCAD 2010
CAD2Shape features::
• Stand-alone CAD to Shapefile conversion
• Optional translation to 2D or 3D shapefiles
• Attach Z value as 'Elevation' data
• Text to 'Labels Theme'
• Text to exploded polyline option. - allows direct translation of CAD Text to visible text in ArcGIS/ArcMap/ArcView. The resultant text and placement will be visually identical to that in the originating CAD drawing
• Attributes translation
• Translate holes / islands /donuts from originating CAD drawing to
• Polygon shapefile
• Extended Entity Data (Xdata) translation
• Translate 3D surfaces to MultiPatch shapefile types
• Filter by Layer, Area, Color, Entity
New features in version 5.0
• Translates all AutoCAD DXF and DWG versions up to and including AutoCAD 2010
• Option to output to raw data file: e.g. CAD to XYZ, CAD to CSV, CAD to BLN (Surfer Blanking file format)
• MPolygon support
• Dimensions/Leader/Tolerance support
• Additional XDATA types
• Length attribute for polylines
• Data suitable for import to Google Earth Pro (shapefiles), and Google Earth Plus (CSV)

This second edition has been expanded to include new and revised sections and provides practical, easy to follow methodologies for a range of calculations used in the design and sizing of heating, ventilating and air conditioning.
The guidance is primarily based on data and procedures contained within the CIBSE Guides, together with other sources such as Building Regulations, with cross-referencing to data sources.
Presented in the form of calculation sheets including design watchpoints, design tips and rules of thumb, the Guide is intended to aid the design process and reduce errors. Calculation sheets are presented in five sections: heating loads, cooling loads, water flow distribution, air flow distribution, and acoustics. Each section is introduced via flowcharts providing an overview of the system design process.

This Part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from metallic coated steel sheet with or without additional organic coatings. The standard establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply when purchased before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. The standard applies to all discontinuously laid self-supporting external profiled sheets for roofing with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building and to transfer any resultant loads and infrequent maintenance loads to the structure. No requirements for supporting construction, design of roof system and execution of connections and flashings are included.

This comprehensive text presents the fundamentals of Computer Fluid Dynamics simply and clearly. The use of Computational Fluid Dynamics to simulate and predict fluid flows, heat transfer and associated phenomena continues to grow throughout many engineering disciplines. On the back of ever more powerful computers and graphical user interfaces CFD provides engineers with a reliable tool to assist in the design of industrial equipment often reducing or eliminating the need for performing trial-and-error experimentation.

A practical, single-source guide tosuccessful strategies for landscape architecture research
As the scope of landscape architecture expands to engage with other disciplines, and streams of information directing this field continue to grow and diversify, it becomes increasingly important for landscape architects to be able to implement a range of effective research strategies when seeking, creating, and validating knowledge. Landscape Architecture Research offers a framework for advancing better design thinking solutions by supplying readers with a system of inquiry tactics that open up a wider range of research possibilities. With a logical and innovative approach that favors legitimacy of knowledge based on collective, grounded practices, rather than strict adherence to protocols drawn only from scientific models, this comprehensive, illustrated guide produces a sound argument for establishing a new paradigm for legitimizing research quality. Landscape Architecture Research presents:
Case studies that show how the range of presented research strategies have been successfully used in practice
New perspective on the relationship between theory, research, practice, and critique, a relationship that is specific to landscape architecture
Detailed coverage of the ways that new knowledge is produced through research activities and practical innovations in landscape architecture
The first and only book on this topic of growing importance in landscape architecture, Landscape Architecture Research keeps professionals and students in step with the latest developments in landscape architecture, and delivers a dynamic and flexible game plan for verifying the integrity of their work.
