in this paper we are going to show the importance of mode identification in microtremor array analysis. the idea come from four concentric ambient noise array recordings with aperture 100 to 1000 meters, performed in southern urban area of tehran near the shrine of imam khomeini. these measurements were part of a comprehensive research project with the aim of determination of deep shear wave ve...

Mashhad city, the second most populous metropolis of Iran, with a population of more than three million, lies between two seismically active regions of Binalood and Kopet-Dagh. In recent years, the city has grown around the South Mashhad (SM) fault zone in the south. Given the vital role of the SM fault in influencing the seismic risk of the city, this study is aimed at the evaluation of the fa...

Ljubljana, the capital of Slovenia, is located in the central region of the country in a shallow sedimentary basin filled with Quaternary deposits. It is one of the most seismically active regions in Slovenia, with some important historical earthquakes that have caused damage and economic losses. The soft sediments are some of the most important factors responsible for the amplification of seis...

Voice stress analysis (VSA) is accomplished by measuring fluctuations in the physiological microtremor present in speech. In this paper, Empirical Mode Decomposition is compared to traditional Fast Fourier Transform in the analysis of the physiological microtremor. The results are expected to show that EMD is better suited in the detection of stress in voice.

Abstract Microtremor array measurements, and passive surface wave methods in general, have been increasingly used to non-invasively estimate shear-wave velocity structures for various purposes. The dispersion curves invert them retrieving S-wave profiles. This paper summarizes principles, limitations, data collection, processing methods. It intends enable students practitioners understand the p...

and Applied Analysis 3 island of Taiwan. In this study, the chosen Kaohsiung Luchu science park is one of the major parks located in the southern part of Taiwan. This park has a total area of 571 hectares, which started construction in the year of 2001 and was completed in 2010. Various hightech industries, such as integrated circuits, precision machines, optoelectronic components, computer per...
