Abstract:

Some experts suggest that urban design plans in US cities may lack adequate coverage of the essential design aspects, particularly three-dimensional design aspects of the physical environment. Digital urban models and information technology tools may help designers visualize and interact with design alternatives, large urban data sets, and 3D information more effectively, thus correcting this problem. However, there is a limited understanding of the impact that these models may have on the quality of the design product and consequently hesitation about the appropriate methods of their usage. T

Abstract:

The simple accumulation-based network identification method (ANIM) in a raster Geographic Information System (GIS) posed by Oâ Callaghan and Mark (1984) has been criticized for producing a spatially uniform drainage density (Tarboton 2002) at the watershed scale. This criticism casts doubt on the use of ANIMs for deriving properties such as overland flow length for nonpoint source pollution models, without calibrating the accumulation threshold value. However, the basic assumption that underlies ANIMs is that convergent topography will yield a more rapid accumulation of cells, and thus, mor

Abstract:

In rock constructions and mining it is important to know the current stress situation in the rock due to safety and construction reasons. Two of the widely used stress measurement methods are overcoring and hydraulic fracturing. Both methods are expensive, need new boreholes, and are complex and time consuming. The methods are also limited by the number of successfully achieved measurements series. An alternative method is therefore investigated by locally relieving stresses around the borehole wall using sawn slots. To determine the stresses in the rock, strain measurements will be done using
