A sophisticated and smart story stiffness system identification (SI) method for a shear building model is applied to a full-scale building frame subjected to micro-tremors. The advantageous and novel feature is that not only the modal parameters, such as natural frequencies and damping ratios but also the physical model parameters, such as story stiffnesses and damping coefficients, can be iden...

Since commercially available profiling systems fail when determining the surface roughness of 3D additive manufactured porous structures, a novel protocol for surface roughness quantification of these porous structures has been developed based on high-resolution micro-CT images. The influence of the noise in the images and the spatial image resolution on the accuracy of the micro-CT-based rough...

A simple hydrothermal route has been developed for the fabricating ZnO hierarchical micro/ nanostructure with excellent reproducibility. SEM and TEM analysis show that the hierarchical rod is a single-crystal, suggesting that many single-crystal micro/nanorods are assembled into ZnO hierarchical micro/nanostructures. The morphologies of the hierarchical rods can be conveniently tailored by chan...

Recent trend in reducing the size of products has given Micro Electrical Discharge Machining (MEDM) a significant amount of research attention. Due to the high precision, low tolerance and good surface quality that it can deliver, MEDM is potentially an important process for fabrication of micro-tools, micro-components and parts with micro-features. This paper briefs and highlights the various ...

Micro-Doppler, induced by micro-motion of targets, is an important characteristic for target recognition once extracted via parameter estimation. However, micro-Doppler is usually too significant to result in aliasing in the terahertz band. According to this problem, a Doppler aliasing free micro-motion parameter estimation method based on the modulo Generalized Hough transform is proposed in t...

1 Mixed traffic, characterized by diverse vehicles, changing composition, lack of lane discipline, etc. is best modeled 2 by micro simulation. However, the majority of the leading micro simulation packages and their calibration 3 methodologies have been developed considering less complex homogeneous traffic. Hence, a methodology for 4 calibrating a micro simulation model for mixed traffic is pr...

The design and fabrication of a piezoelectric micro actuator on a silicon diaphragm is presented for application of micro ink jet. We developed the micro devices for the fluid transference that are fabricated using thick film technologies for ceramic materials and Si micro-machining. The performance of drop ejection was shown from the optimal design parameters. It is closely related to the prec...

Advances in fuel cell applications reflect the ability of reformers to produce hydrogen. This work presents a flexible micro temperature sensor that is fabricated based on micro-electro-mechanical systems (MEMS) technology and integrated into a flat micro methanol reformer to observe the conditions inside that reformer. The micro temperature sensor has higher accuracy and sensitivity than a con...

Abstract The digital control of the latest nanosecond pulsed wave (PW) fibre lasers allows very high flexibility in controlling application total energy to a workpiece, which brings several advantages joining process. By choosing different pulse shapes spatial profiles, it is possible apply low per with precision and accuracy resulting lower heat input. Since each insufficient generate melting,...
