ABSTRACT The epidemic-type aftershock sequence (ETAS) model is widely used in seismic forecasting. However, most studies of ETAS use point estimates for the parameters, which ignores inherent uncertainty that arises from estimating these historical earthquake catalogs, resulting misleadingly optimistic forecasts. In contrast, Bayesian statistics allows parameter to be explicitly represented and...
This paper reviews seismic activity in and around the Kumamoto region before and after the April 16, 2016, Kumamoto earthquake of M7.3 using statistical models such as stationary, two-stage, and non-stationary epidemic-type aftershock sequence (ETAS) models to examine seismicity anomalies. Our findings are summarized as follows. First, most of the earthquake clusters before April 2016 are expla...
این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسلهمراتبی جهت پیگیری فرایند توسعه تأمینکنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه میکند. ابتدا، زمینههای تأمین نیازمند سپس واجد شرایط هریک زمینهها به کمک تصمیمگیری چندشاخصه بهترین-بدترین مشخص میگردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهرهگیری نظرات خبرگان حوزهی خرید استخراجشدهاند. درنهایت، مدل ریاضی ...
The Epidemic Type Aftershock Sequence (ETAS) model is a widely used tool for cluster analysis and forecasting, owing to its ability accurately predict aftershock occurrences. However, capacity explain the increase in seismic activity prior large earthquakes—known as foreshocks—has been called into question due inconsistencies between simulated experimental catalogs. To address this issue, we in...

We report on the study of extremely high energy photons, pions and etas, produced in intermediate energy heavy-ion collisions. Possibility of imaging the final-state phase space in these collisions by the BoseEinstein correlations for photons is critically examined. Invited talk given at the NATO Advanced Research Workshop on the Structure of Mesons, Baryons and Nuclei, Krakow (Poland), May 26 ...
This paper is concerned with the intermediate-term prediction of the forthcoming M7 ~ 8 class earthquake on the plate boundary, off the east coast of Miyagi Prefecture, northern Japan, which is the highest probability among the long-term forecast announced to the public. Regional seismicity in the regions of stress-shadow preceding each of the previous ruptures in 1936 and 1978 shows quiescence...
In a transport model that combines initial state interactions of the photon with final state interactions of the produced particles we present a calculation of inclusive photoproduction of mesons in nuclei in the energy range from 1 to 7 GeV. We give predictions for the photoproduction cross sections of pions, etas, kaons, antikaons, and π + π − invariant mass spectra in 12 C and 208 Pb. The ef...
خوشهبندی یا مجزا کردن یک کاتالوگ لرزهیی به پیشلرزه، زلزله و پسلرزه به دفعات در تحلیل خطر زلزله استفاده شده است. به دلیل سهولت و دسترس بودن کدهای رایانهیی، در اغلب موارد بدون بررسیهای پارامتری، بدین منظور تاکنون بیشتر از الگوریتمهای گاردنر ـ نوپوف و ریزنبرگ استفاده شده است. در مطالعهی حاضر، برای خوشهبندی زلزلهها علاوه بر روشهای سنتی از مدل فضایی ـ زمانی توالی همهگیر پسلرزهها...
Processing metallic alloys under a static magnetic field (SMF) has garnered significant attention over the past few decades. SMFs can influence both thermodynamics and kinetics of solidification process by introducing extra force energy. Eutectic-type (ETAs) are commonly used as research materials due to their featured microstructures. This review aims present theoretical experimental results r...
