Understanding the technology landscape is crucial for the success of the software-engineering project or organization. However, it can be difficult, even for experienced developers, due to the proliferation of similar technologies, the complex and often implicit dependencies among technologies, and the rapid development in which technology landscape evolves. Developers currently rely on online documents...
Correlation based graphical models are developed to detect the dependence relationships among random variables and provide intuitive explanations for these relationships in complex systems. Most of the existing works focus on learning a single correlation based graphical model for all the random variables. However, it is difficult to understand and interpret the massive dependencies of the variables...
Meta-models are widely used to facilitate the analysis and optimization of engineering systems that involve computationally expensive simulations. Kriging is widely used as a meta-modeling technique to build surrogate models. However, the assumption of a stationary covariance structure underlying Kriging does not hold in situations where the level of smoothness of a response varies significantly....
Ultrasonic wire bonding is one of the main methods in the package of the chip and substrate of the chip. The vibrations of transducer were tested. Surrogate-data method of phase-randomized based on correlation dimension is proposed to identify the nonlinear chaos of data obtained by ultrasonic wire bonding system. The result indicate there is nonlinear factor in the axial direction of the amplitude...
According to the fact that heating will affect the image collection, target identification and track, so it will affect the alignment precision of the chips and substrates in the process of chips package. Sequence images were collected through the thermosonic flip-chip bonder under the different heating temperature, their parameters distribute regulation of translation, scale ,rotation under the influence...
