Validation of the accuracy of automatic geodetic monitoring data for research into the vertical displacement of the ground surface caused by hard coal longwall mining

Next Research
This article presents the applicability of Automatic Geodetic Monitoring (AGM) for measuring surface displacements in an area affected by deep mining. The accuracy of the interpreted data was investigated by comparing the height differences determined from the AGM results with the reference height differences obtained by precise levelling. By analyzing

Analytical expressions for reflection coefficients of artificially soft and hard surfaces: dielectric slab loaded with a periodic array of strips over a ground plane

IEE Proceedings - Microwaves, Antennas and Propagation, 1995
Simple and closed form expressions for plane wave reflection coefficients of a dielectric slab loaded with a periodic array of strips over a ground plane are presented for use in antenna applications. In the analysis, a set of integral equations for the fields between the strips and dielectric slab are derived from the three-dimensional boundary value ...

Architect or urban designer’s major task is to create the best possible outdoor environment to the people’s activities. Environmental-friendly technology appreciation in the context of urban architecture may be interpreted as the application of materials covering buildings envelop and ground surface.
