This study focuses on simultaneous vibration suppression and energy harvesting in a broad frequency band. For this purpose, a variant nonlinear energy sink (NES) is developed. The developed variant NES consists of a nonlinear oscillator and an electromagnetic energy harvester. Unlike a true NES,...

This paper introduces a novel approach towards an implementation of head pose estimation techniques for the application of noise control. An existing multi-stage process, which uses convolutional neural network (CNNs), for head pose estimation is modified, implemented, and validated for moving...

A new eye-in-hand/eye-to-hand cooperated visual system in peg-in-hole microassembly work is assisted by coordinate-based augmented reality (AR) through three dimensional (3D)-hybrid visual calibration and servo. The 3D hybrid visual calibration is to combine real camera’s intrinsic parameters...

Experimental and computational studies were carried out on the S-shaped diffusers to determine the impact of the change in curvature of a straight-wall diffuser. A straight diffuser became a curved diffuser at completely different angles as their similar upper and lower limbs (30°/30°, 45°/45°)....

In this paper, estimation of the applied force on a planar catheter is considered. An image processing approach has been chosen as the most suitable tool. For this purpose, we create a comprehensive database of catheters with different shapes and operating forces. Using image processing...

We propose a simple microfluidic droplet generator for controlling the droplet size over a wide range. A planar co-flow device was developed with controllable c- phase channel width using a deformable wall structure. The design was benefited from the increased shear force due to the channel...

Braiding is a manufacturing technique in which material yarns are repeatedly interlaced to create a preform. The preform is impregnated with a polymer matrix to create a braided composite. Several studies have investigated the tensile, compressive and torsional behaviour of braided composites and...

Cold spray is a deposition method developed for manufacturing metallic coatings by impacting high-velocity metallic powders on a substrate surface at around room temperature. Because of the low temperature of impacted particles, no oxidation or phase transformations occur during spraying....

It has been widely accepted that stress and strain fields near the crack tip govern crack propagation behavior. In most cases, an elasto-plastic analysis is required to determine local stress and strain fields around the crack tip due to the high stress concentration. However, complexities of...
