Package delamination is a common problem in electronic packaging, and this study focused on the low-profile fine-pitch ball grid array (LFBGA) and plastic ball grid array (PBGA) package of composite and metal bonding and bonding mechanism to decrease the occurrence of delamination. In LFBGA, the physical and chemical properties were discussed by roughness and pure copper/nickel bonding experiment...
A wireless localisation scheme which requires just one reference device to estimate the mobile location is presented. The proposed scheme utilises the joint time-of-arrival and angle-of-arrival estimation of the line-of-sight path measured at both mobile and reference devices to construct areas of possible mobile devices (APMDs). The intersection of these APMDs will give an estimation of an MD location...
In recent years, the emerging bio-chip technology has used external powered pumps for fluidic pumping and mixing. The short-term capillarydriven micromixers with complex mixing structures also showed large potential for mixing devices. This reported work demonstrates the longterm capillary-driven meander micromixer with the planar design, short mixing distance and power-free rapid fluid, transport...
In this paper, a video stabilization technique is presented. There are four steps in the proposed approach. We begin with extracting feature points from the input image using the Lowe SIFT (scale invariant feature transform) point detection technique. This set of feature points is then matched against the set of feature points detected in the previous image using the Wyk et al. RKHS (reproducing kernel...
This study presents a new method of analyzing whether a vehicle is in a dangerous driving condition while travelling along a highway. We use data from various sensors installed on the vehicle, which represent the driving attributes associated with a particular driving scenario, as inputs to our system. However, as some of these sensors may be dependent on each other, using redundant attributes to...
Silica nanowires decorated with silver nanocrystals on quartz substrate were employed as SERS substrates. The substrates features reusablity, backside measurement, and wide measuring range from >0.1 M to near single molecule detection, tested on Rhodamine 6G.
The purpose of this system is to reduce the rate of dangerous events caused by various driving factors. We compose a driving relational map as the system inputs factors of driver behavior, nearby vehicles and roadway factors, and then put this driving relational map into the matching process with dangerous driving relational maps. If the similarity between the driving relational map and one of the...
Three-pair AlGaN/GaN multiple quantum well structure with superlattice was grown using metal-organic chemical vapor deposition system. The AlGaN barrier and GaN well of the MQW were grown by atomic layer deposition and conventional growth, respectively.

This paper applies a modified cascaded fuzzy reasoning Petri net (CFRPN) model to analyze dangerous driving events on a freeway. The dangerous driving events can be divided into two groups: (1) the interaction between a driver's vehicle and the road environment, and (2) the interaction between a driver's vehicle and nearby vehicles. These two classes of driving events may occur simultaneously and...
