This paper presents the application of micro/macromechanics models and optimization techniques for the optimum design of pultruded glass fiberreinforced plastic composite I-beams with respect to material architecture: fiber orientations and fiber percentages. The beams are subjected to transverse loading, and beam deflection, buckling resistance and material failure are considered as multiple o...

Several factors must be considered in deciding which mesh to use for a ventral hernia repair. Open hernia repairs with no exposure of mesh to viscera can be performed with unprotected synthetic mesh, preferably a "lightweight" option. For open repair with high risk for fascial dehiscence and visceral exposure to mesh, and for open underlay repair and laparoscopic underlay repair, recommendation...

Stable ductile crack growth in 3 mm thick AISI 304 stainless steel specimens has been investigated experimentally and numerically. Multi-linear Isotropic Hardening method coupled with the Von-Mises yield criterion was adopted for modeling elasto-plastic behavior of the material. Mode-I CT fracture specimens have been tested to generate experimental load-displacement-crack growth data during sta...

Abstract Biomethanation is a prospective biogas upgrading method to integrate renewable energy grid with existing grid. Biomethane can directly substitute fossil natural gas and be used in all sectors. The selection of packing material for the ex-situ biomethanation biotrickling filter reactors based on physical chemical characterization carrier material. selected supports hydrogenotrophic meth...

We annotate individual posts following the approach in [1], [2]. Tweets are grouped by topic based on included topic hashtags. For example, tweets relating to the topic of president Barack Obama contain the hashtag #obama within them. The topic-related tweets often contain other hashtags which we assign a preliminary sentiment probability (positive and negative) using the Multinomial Naive Baye...
