This paper studies the efficiency of subgrade stiffening next to the track as a mitigation measure for railway induced vibrations by means of a two-and-a-halfdimensional coupled finite element – boundary element methodology. The pyhsical mechanism is interpreted in the frequency–wavenumber domain, illustrating that the stiffened block of soil next to the track can act as a wave impeding barrier...

Mesenchymal stem cell (MSC) differentiation is mediated by soluble and physical cues. In this study, we investigated differentiation-induced transformations in MSC cellular and nuclear biophysical properties and queried their role in mechanosensation. Our data show that nuclei in differentiated bovine and human MSCs stiffen and become resistant to deformation. This attenuated nuclear deformatio...

The predominant use of FBG sensors to characterize the residual stress state in composite materials date does not permit absolute strain measurements. reason for this is loss connection between sensor and laminate during phase transitions resin. Thus, points significant changes measurement signal (e.g. bonding temperature) need be used evaluation. For fiber metal laminates (FML) however, gages ...

The objective of this study was to design custom-made prosthesis in a certain population, the morphometry needs to be measured. The results of this study were expected to provide basic data to design the ideal size of the total knee arthoplasty prosthesis for Indonesian population. This was an anthropometric study conducted on 100 healthy Indonesian population based on Computer Tomographic (CT)...

This paper proposes an agent with particle swarm optimization (PSO) based on a Fuzzy Markup Language (FML) for students learning performance evaluation and educational applications, and the proposed agent is according to the response data from a conventional test and an item response theory. First, we apply a GS-based parameter estimation mechanism to estimate the items parameters according to ...

Abstract Fiber metal laminates (FML) are hybrid materials consisting of and composite layers. They have great mechanical fatigue properties. However, interface between layers can be critical for their final In this paper, process determination some fracture parameters in unusual FML material is described. Experimental tests following ASTM norm were conducted using Double Cantilever Beam (DCB). ...
