This paper presents a depth map restoration scheme for both the raw and projected depth map from Kinect v2 sensor. Based on IR-depth consistency, erroneous depth readings around foreground objects are removed by an edge aware consistency correction method. Moreover, a joint adaptive kernel regression algorithm is designed to upsample the sparse depth map after the projection from Kinect v2 sensor's...
This paper presents a novel approach to balance assistance and joint load reduction for human bipedal walking. We introduce a new type of wearable robot, called Supernumerary Robotic Limbs (SRL), that provides two additional legs for augmenting stability and reducing the loads on human leg joints. Unlike exoskeletons, the SRL is kinematically independent of the human skeletal structure, and can therefore...
In this study, the effect of pad shape on current density and temperature distributions in solder joints has been investigated by three dimensional thermo-electrical finite element analysis. The simulation results show that square, hexagonal, octagonal and rounded pads with the same thickness/volume generate different current density and temperature distributions. The maximum current densities in...
Lead-free solder alloy is popular in electronic industry due to its environmental friendly characteristic. However, the interfacial reaction faces the thermal challenge caused by the increased melting temperature of lead-free solder alloy. In the present work, a composite Ni-P-ZrO2 (15 at.% of P) layer was developed by electroless plating as novel under bump metallization (UBM). In order to homogeneously...

It is widely observed in the industry that defective dies tend to occur in groups of systematic pattern. These are so-called defect clusters. There are many proposed methods to achieve cluster classification and recognition with different degree of accuracy and limitations. Many of these methods, although powerful, generally do not actually detect the presence/absence of a cluster but simply segments...
