Reverse dual-rotation friction stir welding (RDR-FSW) is a novel variant of conventional friction stir welding (FSW) process.
Reverse dual-rotation friction stir welding (RDR-FSW) has great potential to obtain appropriate welding conditions through adjusting the independently rotating tool pin and surrounding shoulder.
The reverse dual-rotation friction stir welding (RDR-FSW) has the capability to adjust the heat generation because of the separately designed tool shoulder and tool pin.
Incorporation of dual axis rotation enhances axial mixing by 60to90%0% in comparison to single axis rotation.
We present micromirrors actuated by self-aligned, high aspect ratio, vertical electrostatic combdrives with multi-level electrical isolation that allows bi-directional and dual-mode (independent rotation and piston motion) operation.
In the case of SPECT, this involved adoption of dual detectors and robust rotation gantries rather than the initial counter-balanced single head systems.
In this thesis, we use dual quaternion to replace rotation matrix R and translation vector which expressed object's transformation in usual.
We observed that template based rotation and dual regression are approximately equivalent in detecting fcMRI differences between young and old subjects, demonstrating similar effect sizes for group differences and similar reliability metrics across 12 cortical networks.
Both template based rotation and dual-regression demonstrated larger effect sizes and comparable reliabilities as compared to seed based correlation analysis, though all three methods yielded similar patterns of network differences.
At the same time, Figure 1d shows that MAG (Dual Technique Magnetometer) observed rotations in the B φ component of the magnetic field, which are indicative of field-aligned currents (FACs) [e.g., Bunce et al., 2008].
The purpose of this study was to compare the in-vitro biomechanical response of two different dual rod designs under axial rotation loading.
