Electric Arc Furnace Slag and Blast Furnace Dust, Use for the Manufacture of Asphalt Concrete for Roads

This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...

A Hierarchical Segmentation Approach towards Roads and Slopes for Collapse Recognition

Color image processing is widely used in Intelligent Transport System, but seldom used in recognition of roads and slopes collapse. The application can reduce time and efforts. And the roads and slopes segmentation is the first and key step of the recognition system, which is a challenging and difficult problem. One of the problems is the presence of different types of roads and slopes. In this...

Assessment of uncertainty for coal quality-tonnage curves through minimum spatial cross-correlation simulation

Coal quality-tonnage curves are helpful tools in optimum mine planning and can be estimated using geostatistical simulation methods. In the presence of spatially cross-correlated variables, traditional co-simulation methods are impractical and time consuming. This paper investigates a factor simulation approach based on minimization of spatial cross-correlations with the objective of modeling s...

Cross-Roads in Studies of Galaxy Evolution

Studies of galaxy evolution at optical and near-infrared wavelengths have reached an interesting point in their historical development and the arrival of a new millenium provides an appropriate occasion to review the overall direction in which this subject is moving. The aim of this short essay is to emphasize the qualitatively different datasets now arriving and the more detailed and challengi...
