Effect of age on ocular microtremor activity.
BACKGROUND Ocular microtremor (OMT) is a high-frequency tremor of the eyes. It is present in all individuals and is related to brainstem activity. The OMT signal appears as an irregular oscillatory movement with intermittent burst-like components. The clinical interest in OMT has centered on its use in the assessment of the comatose patient, with broad agreement among authors of its prognostic ...
متن کاملdetermination of natural frequency of soil vibration in sarcheshmeh copper mine, using microtremor records
it is well known that ground-shaking site effect caused by an earthquake can vary significantly within a small distance. this is because at sites having soft soil and/or topographic and basement undulations, seismic energy gets trapped, leading to amplification of vibration that may cause considerable damage to man-made structures. theoretical analysis and observational data have shown that eac...
متن کاملwoman-defined identity: analysis of selected poems of adrienne rich
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
Ocular microtremor measurement using laser-speckle metrology.
We describe a novel, noninvasive measurement approach for recording a small involuntary tremor of the eye known as ocular microtremor. The method is based on measuring out-of-plane angular displacements of a target by using laser-speckle correlation of images recorded in the Fourier plane of a lens. The system has a dynamic range of 4 to 5000 μrad, resolution of 4 μrad, and a bandwidth of 250 H...
متن کاملcomparison of ssr and h/v microtremor data analysis techniques
the destructions caused by many recent earthquakes shows that the subsurface structure directly affects the ground motions. especially in areas with possible seismic hazard expectation, expansion of cities has come up with detailed vulnerability analysis. therefore, site response investigation is a key step in every microzonation study. one of the best approaches for understanding the geologica...
