Automatic classification of seismic events within a regional seismograph network

Four decades of ozonesonde measurements over Antarctica

[1] Ozonesonde observations from Syowa and the South Pole over more than 40 years are described and intercompared. Observations from the two sites reveal remarkable agreement, supporting and extending the understanding gained from either individually. Both sites exhibit extensive Antarctic ozone losses in a relatively narrow altitude range from about 12 to 24 km in October, and the data are con...

Uncertainty Analysis in Seismic Event Location

Uncertainty in event locations derived from seismic data is caused by errors in the arrival times of picked phases, misidentification of seismic phases, and errors in the travel-time model used in the location process. The event mislocation induced by these error sources is affected by the number and spatial distribution of stations that record an event. This project is developing a statistical...

examining the relationship between fear of negative evaluation and communication strategies by iranian efl learners

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...

Evaluation of the accuracy of panoramic radiograph in determining the location of the lingula

Introduction: The purpose of this study was to determine the accuracy of panoramic radiograph in locating the position of lingula as an index to estimate the location of mandibular foramen. Methods: The distance measurement in this study was carried out on 30 dry mandibles, composed of at least 2 first molars and one canine. Photography and panoramic radiography of the mandible was performed...
