Ground-state properties of the deformable jellium

Physical Review A, 1989
A self-consistent calculation is done to evaluate relevant ground-state properties of the electron gas in the deformable-jellium model. We get the melting point of the Wigner crystal and the ground-state energy per particle at all densities. The single-particle state function in the Slater determinant is expanded in a basis of periodic functions.

The ground-state deformation of98Sr

Zeitschrift f�r Physik A Atomic Nuclei, 1987
The half-life of the first excited state (21+) of98Sr has been determined through the measurement of delayed γ-γ coincidences at the fission product separator OSTIS to t1/2=2.74(12) ns. This value is smaller than those obtained earlier from β− — conversion electron delayed coincidences and it indicates a stronger collectivity of the 21+→01+ transition ...

Ground Deformation from Ground-Based SAR Interferometry

2013
An in-depth analysis of the last two images acquired by the ground-based interferometric synthetic aperture radar system installed on Stromboli before the 5 April 2003 explosion allowed us to detect the precursory signals of the explosion related to ground deformation.

Inelastic Deformation of Pipelines Induced by Temporary Ground Deformations

Volume 2: Pipeline Safety Management Systems; Project Management, Design, Construction, and Environmental Issues; Strain Based Design; Risk and Reliability; Northern Offshore and Production Pipelines, 2018
This paper describes a new design method to obtain the inelastic deformation of pipelines induced by temporary ground deformations. The proposed design method consists of an elastic solution and a strain conversion procedure which was developed to predict the inelastic strain distribution by using the elastic solution and a stress-strain curve ...

The Variability of Deformation Demand with Ground Motion Intensity

Proceedings of the 6th International Conference on Computational Stochastic Mechanics(CSM-6), 2011
Abstract The use of Nonlinear Dynamic Analyses is coupled to the demands produced by earthquakes of different intensities. The uncertainties associated with the demands are highly dependent on the variable adopted as the intensity measure (IM). This generates the need to compare different IMs and in particular the dispersion of the demand measure in ...

Precipitation, Groundwater and Ground Deformation

1990
Strainmeters and tiltmeters installed on or at a shallow part under the ground surface record ground deformations caused by rainfall. Such deformations are detected to a depth of several ten meters with these instruments, and accordingly they are main noises to observations of crustal movements and/or earth tides with these instruments.

Ground deformation monitoring in the UAE

2023
Σε αυτή τη διατριβή μελετήθηκαν οι παρελθούσες και οι παρούσες εδαφικές παραμορφώσεις στο ανατολικό τμήμα του Εμιράτου του Αμπου Νταμπι και στην πόλη του Αμπου Νταμπι. Η πρώτη περιοχή είναι κυρίως αγροτική όπου η εξάρτηση της από τα υπόγεια ύδατα είναι καταγεγραμμένη, ενώ η επέκταση της πόλης του Αμπου Νταμπι προς το εσωτερικό των Ηνωμένων Αραβικών ...

Ground-Deformation Methods and Results

1996
A comprehensive volcano-monitoring program should include techniques to measure surface deformations in order to contribute to a complete characterization of volcanic behavior. Conventional modern geodetic techniques provide useful tools for the capture of discrete or continuous ground-deformation data. Baseline data volcano deformation observed during

Impact of Ground Deformation on Structures

1983
The components of ground movement arrived at in earlier sections — namely, subsidence vz and horizontal displacement v, together with the factors of tilt v z ’ , surface curvature v z ” , and linear change s derived from them — serve the subsidence engineer as a basis for determining surface damage.
