Abstract: A high-resolution quartz tiltmeter was developed for measurement of small movements. It is used to record earth deformation during many months. This deformation is due particularly to earth tides. The fast Fourier transform ...

Abstract: A very sensitive tiltmeter developed by the writers is used to study the small movements in civil engineering structures such as retaining walls, dams, foundations, etc. The use of this instrument, made of silica, is ...

Abstract: The detection and analysis of land use changes in the urban environment is an important issue in planning. Remote sensing and geographic information systems are considered as the most efficient techniques for this type of ...

Abstract: This study presents a method of estimating the modulus of elasticity of an existing multilayer pavement system. The method is based on the interpretation of a measured deflection basin. The deflections of the existing ...
