This paper describes a novel filtering method (FIMER) to extract three critical yield loss components: gross yield loss from parametric problems or from clustering of defects, repeated yield loss from mask defects or from lithography margin, and random yield loss mainly from particles. It is shown by simulation that FIMER is not only superior to the conventional windowing method in extracting r...

In this paper we analyse congestion in TCP over ATM-UBR, in particular the association between the congestion measures at the ATM physical and TCP transport layers. In addition to the commonly used metrics, cell loss ratio (CLR) and packet retransmission ratio (PRR) two new indicators, protocol level congestion association factor (PLCAF) and CLR-PRR correlation coe cient are used. CLR and PRR a...

In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...
