Currently, visually described borehole samples are the primary input for large-scale 3D geological models of the subsurface, both when modelling architecture and composition. Cone penetration tests are rarely used and to a limited extent only. There are several reasons why it is of interest to utilize CPT data for geological and lithological modelling of the Dutch subsurface: 1) CPTs are more a...

Objectives. The Cognitive Performance Test (CPT) is a functional assessment for persons with dementia. The study purpose was to evaluate the reliability, discriminant, and concurrent validity of the CPT. Method. The CPT was tested against other measures of cognition (Standardized Mini Mental Status Exam (SMMSE) and Assessment of Motor and Process Skills-Process scale (AMPS-Process)). Participan...

Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

Abstract The system of seabed Cone Penetration Test (CPT) is a kind equipment for offshore investigations. Seabed CPT used to assess multiple physical properties marine sediments. Constant-rate penetration mechanism the core part CPT, which adopts dual-cylinder drive penetrate probe rod into seafloor sediments at constant speed (2cm/s). At present, domestic and its almost all rely on imports. I...

Due to the introduction of Eurocode 8, the structural design for seismic and dynamic effects has become more significant in Hungary. This has emphasized the need for more effort to describe the behavior of structures under these conditions. Soil conditions have a significant effect on the response of structures by modifying the stiffness and damping of the soil-structural system and by modifyin...
