it is well known that damaged structural members may alter the behaviour of the structures considerably. careful observation of these changes has often been viewed as a means to identify and assess the location and severity of damages in structures. among the responses of a structure, natural frequencies and natural modes are both relatively easy to obtain and independent from external excitati...

Modal logics and their models have been used to speak about and represent topological spaces since the 1940s [22, 23, 16, 17]. Examples include Tarski’s programme of algebraisation of topology (“of creating an algebraic apparatus for the treatment of portions of point-set topology,” to be more precise) which involved modal logic S4 [17], and the use of the extension of S4 with the universal mod...

According to the great importance of safety in aerospace industries, identification of dynamic parameters of related equipment by experimental tests in operating conditions has been in focus. Due to the existence of noise sources in these conditions the probability of fault occurrence may increases. This study investigates the effects of noise in the process of modal parameters identification b...

this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...

The purpose of this paper is to obtain the common fixed point results for two pair of weakly compatible mapping by using common (CLR) property in partial metric space. Also we extend the very recent results which are presented in [17,  Muhammad Sarwar, Mian Bahadur Zada and Inci M. Erhan, Common Fixed Point Theorems of Integral type on Metric Spaces and application to system of functional equat...

Deformable registration of images obtained from different modalities remains a challenging task in medical image analysis. This paper addresses this problem and proposes a new similarity metric for multi-modal registration, the non-local shape descriptor. It aims to extract the shape of anatomical features in a non-local region. By utilizing the dense evaluation of shape descriptors, this new m...
