A probabilistic seismic hazard assessment in terms of Arias intensity is presented for the city of Tehran. Tehran is the capital and the most populated city of Iran. From economical, political and social points of view, Tehran is the most significant city of Iran. Many destructive earthquakes happened in Iran in the last centuries. Historical references indicate that the old city of Rey and the...

The inversion of scattered waves in seismic exploration is a hot and difficult problem related fields. We propose hypothesis: the local wave field near each point on profile has relationship with minimum distance between that scatterer, this can be recognized by convolutional neural network (CNN). Based this, designed CNN steadily classify identify wavefield point, realize imaging scatterer. ne...

The paper describes a model-integrated program synthesis environment for computer-based system applications. In Model-Integrated Program Synthesis (MIPS), domain-specific, multiple-view models represent the software, its environment and their relationships. Model interpreters translate the models into the input languages of static and dynamic analysis tools, and application specific model inter...

Query translation in cross-language information retrieval (CLIR) can be done by employing dictionaries, aligned corpora, or machine translators. Scarcity of aligned corpora for various domains in many language pairs intensifies the importance of dictionary-based CLIR which motivates us to use only a bilingual dictionary and two independent collections in source and target languages for query tr...

The building of complex, large-scale industrial applications necessitates the integration of models into the problem solving process. This paper describes a modelintegrated program synthesis environment for computerbased system applications. In Model-Integrated Program Synthesis (MIPS), domain-specific, multiple-view models represent the software, its environment and their relationships. Model ...

Manual stratigraphic interpretation of modern 3-D seismic images is extremely timeconsuming. We present a method based on nonstationary predictive signal/noise separation for automatically recognizing the occurence of a predefined pattern in seismic images. The method is tested on 2-D synthetic and real seismic images, and is shown to reliably detect the presence of unconformities in both.

Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...
