The martensitic–austenitic phase transformation of a polycrystalline shape memory alloys (SMA) occurs gradually over a range of temperatures even though the monocrystal undergoes a first-order transition (at a single temperature). Factors such as material inhomogeneities and internal stresses in a polycrystal are believed to cause the spread in transformation temperatures. In this work, we assu...

The history of blood pressure (BP) waveform analysis is almost as undulatory as the waveform itself. The development of the sphygmograph in the mid-19th century led to a relatively brief, albeit intense, interest in the interpretation of the BP waveform. This was perhaps more an art than a science, and interest in the sphygmograph and the waveform declined after the introduction of the cuff-bas...

Many cognitive processes rely on representations of magnitude, yet these representations are often malleable (H. Helson, 1964; J. Huttenlocher, L. V. Hedges, & J. L. Vevea, 2000; A. Parducci, 1965). It is likely that factors that affect these representations in turn affect the psychological processes that rely on them. The authors conducted 4 experiments to investigate whether language-expressi...

In this paper we introduce the persistent magnitude, a new numerical invariant of (sufficiently nice) graded persistence modules. It is weighted and signed count bars module, in which bar form [a,b) degree d counted with weight (e−a−e−b) sign (−1)d. Persistent magnitude has good formal properties, such as additivity respect to exact sequences compatibility tensor products, interpretations terms...

Image hashing allows compression, enhancement or other signal processing operations on digital images which are usually acceptable manipulations. Whereas, cryptographic hash functions are very sensitive to even single bit changes in image. Image hashing is a sum of important quality features in quantized form. In this paper, we proposed a novel image hashing algorithm for authentication which i...

this paper focuses on aftershocks behavior and seismicity along some co-seismic faults for large earthquakes in iran. the data of aftershocks and seismicity roughly extracted from both the institute of geophysics the university of tehran (igut) and international seismological center (isc) catalogs. apply some essential methods on 43 large earthquakes data; like the depth, magnitude as well as t...
