In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration, nonlinear parametric vibration and wind f...

This paper offers a framework for examining the relationship between social, instrumental, and technological determinants of participation through social media (Dahlberg, 2004) using a discursive approach based in the concepts of frames and framing (Goffman, 1974; Snow & Benford, 1992). We apply our multideterminant framework to investigate participatory dynamics on YouTube in the case of clima...

The objective of this study was to investigate the effect of partial longitudinal lateral meniscectomy on the mechanics of the knee joint. A 3D fibril-reinforced finite element (FE) model of the knee joint was used for this purpose. The model includes bones, cartilages, menisci as well as four major ligaments. The cartilages and menisci were modeled as fully saturated porous media reinforced by...

The ability to model and predict the popularity dynamics of individual user generated items on online media has important implications in a wide range of areas. In this paper, we propose a probabilistic model using a Self-Excited Hawkes Process (SEHP) to characterize the process through which individual microblogs gain their popularity. This model explicitly captures the triggering effect of ea...

The effective response of a periodic fibre reinforced material to SH wave propagation is studied using the method of asymptotic homogenization, complex variable theory and multipole expansions. The quasi-static limit of the effective properties is calculated when the wavelength is much longer than the defining lengthscale of the microstructure. The method developed allows the determination of t...

Actors of public interest today have to fear the adverse impact that stems from social media platforms. Any controversial behavior may promptly trigger temporal, but potentially devastating storms of emotional and aggressive outrage, so called online firestorms. Popular targets of online firestorms are companies, politicians, celebrities, media, academics and many more. This article introduces ...

• Hyperelasticity framework is used to derive new nonlinear wave equations of radially propagating finite shear displacements in axially symmetric elastic bodies with helical fibers. Such G ( t , R ) are governed by a general PDE = 1 ∂ f where function that depends on the form stored energy function. For Mooney-Rivlin materials, above cylindrical equation becomes linear : α + which again, when ...
