the tabriz fault in northwest of iran is the important geological structure in our country which historical earthquakes were recorded around it. the purpose of this paper is the study of tabriz fault seismotectonic activity. the method of research is drawing 23 cross section vertical to tabriz fault between tabriz and bostan-abad distinguish mountain-front faceting, mountain-front sinuosity and...

In the fault diagnosis of automaton, the vibration signal presents non-stationary and non-periodic, which make it difficult to extract the fault features. To solve this problem, an automaton fault diagnosis method based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD) was proposed. Based on the advantages of the morphological component analysis method i...

although ilkhanids (1256-1353 ce) initially selected maraghe and then tabriz as their capital, the thought of founding a new city as a symbol of their kingdom encouraged them to establish soltanieh. ghazan khan’s goal of constructing the newly-built capital was accomplished during uljayto’s kingdom; a project that lasted for about 10 years (704-713 ah). although soltanieh’s fast development mad...

different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...
