In this paper, we propose a chip-scale Chemical mechanical polishing (CMP) model based on the Greenwood–Williamson theory combining the effects of both the pad bulk deformation and the feature size, which are mainly responsible for global pressure distribution and feature-scale removal rate variation, respectively. A reference camber is first constructed to simulate the pad bulk deformation, which...
To accurately estimate the stage-of-charge of the lithium ion battery, a method based on Multirate Extended Kalman Filter is applied. A equivalent circuit model is built and the mode parameters are estimated based on the experiment data of charging and discharging the battery. The coulomb counting, Single Rate Extended Kalman Filter and Multirate Extended Kalman Filter are used to predict the SOC...
The degradation of chlorinated phenoxy acetic acids herbicides 2,4-D (2,4-dichlorophenoxyacetic acid) in aqueous solution using ultrasound-enhanced ozonation was studied in this paper. The effect of different parameters such as pH value and 2,4-D initial concentration in reaction solution on the kinetics of degradation of 2,4-D was investigated in an experimental reactor. It is found that the degradation...
Analog circuit synthesis is a very important step of analog design automation flow. Due to the great effects on circuit performance degradation from the parasitic, it is a great time-consuming task, especially when the feature size is becoming smaller and smaller, operation frequency is becoming higher and higher, and the circuit scale is becoming larger and larger. In this paper, we present a parallel...
In LTE, AC barring check is performed by UEs before initiating an RRC connection. In some cells with a low access probability, the UEs may have to keep retrying access in the serving cell which results in higher connection failure and longer access delay. We therefore propose balancing the UEs by adjusting the cell reselection criteria based on the access probability in the serving cell and neighboring...
