Abstract: Most near-field (NF) localization algorithms cannot deal with the underdetermined case, while those which can are computationally expensive due to employment of fourth-order cumulants. In ...
Abstract: In Computer-Aided Process Planning (CAPP), machining feature recognition is the first and essential step for planning the manufacturing of the designed model. Due to the rapid variation in ...
This paper surveys econometric innovations related to differences-in-differences estimators and to event-study models with time-varying treatment effects. Our discussion highlights tricky ...
