condition monitoring of bldc motors due to their important applications is gaining more and more significance. rotor eccentricity is one of the most important sources of faults in these motors. up to now, detection methods of this fault under nonstationary conditions are limited to complicated and time-consuming methods using wavelets and cohen class algorithms which are difficult to implement ...

This paper describes the method used in the design of a 26 million transistors chip at BULL to verify the timing performance using the hierarchical timing analysis tool HiTas as well as the interactive path browser Xtas. Those tools have been designed at UPMC and are now commercialized by AVERTEC. The complexity is handled by partitioning the analysis according to the hierarchical partitioning ...

This paper describes a two-stage statistical approach supporting content-based search in image databases. The first stage performs correspondence analysis, a factor analysis method transforming image attributes into a reduced-size, uncorrelated factor space. The second stage performs as-cendant hierarchical classification, an iterative clustering method which constructs a hierarchical index str...

Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...

The purpose of this study was to investigate the structural pattern of the effect of corporate governance mechanisms (internal organization) on audit quality considering the role of the intermediary variable of behavioural components of auditors. The statistical population of this research is independent auditors and auditors working in audit firms. A sample of 395 people was selected by simple...

In this work, hierarchical WO3 core-shell microspheres were synthesized via a facile template-free precipitation method. Gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial WO3 nanoparticles. The synthesized and commercial powders were characterized by X-ray diffraction, scanning electron microscop...

the main objective of this study was to investigate how months cluster in any thermal regions based on temperature. for this purpose, the mean of daily temperature data have been provided using 620 synoptic and climatology stations. then, mean temperature was converted for any station, based on solar calendar, and maps of mean daily temperature have been interpolated using kriging method. spati...
