Damage detection has been focused by researchers because of its importance in engineering practices. Therefore, different approaches have been presented to detect damage location in structures. However, the higher the accuracy of methods is required the more complex deliberations. Based on the conventional studies, it was observed that the damage locations and its size are associated with dynam...
We propose an original model for noise analysis, transformation, and synthesis: the CNSS model. Noisy sounds are represented with short-time sinusoids whose frequencies and phases are random variables. This spectral and statistical model represents information about the spectral density of frequencies. This perceptually relevant property is modeled by three mathematical parameters that define t...
Received: 19 Oct, 2012 Accepted: 22 Dec, 2012 Background & Aims : Polycystic Ovary Syndrome (PCOS) as a heterogeneous disease is one of the most usual women endocrine disorders and the leading causes of infertility by reason of unovulation. PCOS affecting about between 5 and 10 percent of females. The results of recent studies indicated that vitamin D has an important role in calcium home...
The rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. For noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. In this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, Generaliz...
