Abstract: A pair of quartic polynomials in the tangent of the output angular displacement were derived for two TTTR mechanisms designed in such a way that the serially connected pairs of Hooke joints ...

Abstract: In this paper, we study a class of in-parallel platforms whose six legs are connected either singly or in a pair-wise fashion at the vertices of a quadrilateral top platform and a pentagonal ...

Abstract: Ultrasound velocity is one of the key acoustic parameters for noninvasive diagnosis of osteoporosis. Ultrasound phase velocity can be uniquely measured from the phase of the ultrasound signal ...

Abstract: Results are presented for a series of laboratory tests that were undertaken to characterize the tensile properties of an engineered cementitious composite (ECC) mix, which is a mortar-based composite reinforced with synthetic ...

Abstract: This research resolves an inconsistency problem that arises from assessing circularity of workpiece measured by coordinate measuring machines (CMMs). Although the notion of circularity is employed ...

Abstract: Based on the vibro-acoustic coupled model of an infinite bare plate, using the impedance transfer matrix, the analytical model predicting the noise reduction performance of a void decoupling ...

Abstract: An experimental program was conducted to investigate the viability of using engineered cementitious composite (ECC) shotcrete as in-plane shear reinforcement for concrete masonry wallettes. Twenty-six mortared or dry-stacked ...

Abstract: In this paper, based on the combination of the back-propagation network (BPN) and the self-organizing map (SOM), a groundwater level forecasting model is proposed, named improved multisite SOM-BPN model. In the proposed ...
