Seismic Passive Control of Cable-Stayed Bridges
Shock and Vibration, 1995 A three-dimensional modeling procedure is proposed for cable-stayed bridges with rubber, steel, and lead energy dissipation devices. The passive control technique is investigated by considering the response of bridge models with and without energy ...

Groundwater Monitoring with Passive Seismic Interferometry
Journal of Water Resource and Protection, 2017 Passive seismic interferometry takes advantage of natural ambient seismic noise generated by the wind, the storms and the human activities (e.g. cars, trains and hereafter pumps) to recover the slight variations of the seismic wave velocity induced by changes in the groundwater level.

DETERMINATION OF COORDINATES OF SEISMIC WAVE SOURCE BY AMPLITUDE METHOD OF PASSIVE LOCATION
Геодинамика и тектонофизика, 2015 The paper presents results of the mathematical synthesis of the method of passive location of a seismic wave source. The method employs measurements of regular attenuation of seismic oscillation amplitudes.

Fiber-optic push-pull sensor systems [PDF]
, 1992 Fiber-optic push-pull sensors are those which exploit the intrinsically differential nature of an interferometer with concommitant benefits in common-mode rejection of undesired effects.

NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]
, 2010 The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...

Methodological procedure for applying geophysics to geotechnical studies in Luanda City, Angola
Minería y Geología, 2018 The use of the surface wave’s analysis in its passive and active variants was jointly assessed by the shallow seismic refraction. It allows determining dynamic parameters from the longitudinal and transverse velocities, obtained from seismic methods. For
