Design, materials, and performance are important factors in the research of bone tissue scaffolds. This work briefly describes the bone scaffolds and their anatomic structure, as well as their biological and mechanical characteristics. Furthermore, we reviewed the characteristics of metal materials, inorganic materials, organic polymer materials, and composite materials. The importance of the b...

 High-aspect-ratio mechanical structures fabricated using deep reactive ion etching generally have a non-rectangular profile. The profile can severely influence the mechanical performance of the device. We have quantified the profile shape for through-wafer etched beams and presented an analytical model to evaluate the effect of profile shape on silicon lateral suspensions. A design methodolog...

We present a systematic study of the effect of crowdsourced translations on Machine Translation performance. We compare Machine Translation systems trained on the same data but with translations obtained using Amazon’s Mechanical Turk vs. professional translations, and show that the same performance is obtained from Mechanical Turk translations at 1/5th the cost. We also show that adding a Mech...

An approach to solve the mechatronic design problem is to formulate the problem as a multiobjective dynamic optimization problem (MDOP), where kinematic and dynamic models of the mechanical structure and the dynamic model of the controller are considered besides a set of constraints and a performance criteria. This design methodology can provide a set of optimal mechanical and controller parame...

Effect of different fillers on natural rubber compounds was investigated through curing, mechanical properties and morphology studies for improving mechanical performance of rubber articles. In this work, natural rubber blends with Silica as Single-filler compounds, and blends with Silica and Carbon black as Bi-filler compounds were considered. Then, natural rubber blends with Silica, Carbon bl...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...
