Blind source separation (BSS) is one of the most active research areas in neural networks. Previously, we proposed a BSS algorithm which exploited orientation histograms in a joint distribution of observed mixtures. Although the algorithm worked well for simultaneous mixtures of sources, interaural source propagation delays almost always exist in natural(More)
This paper describes a new simple process model for photoresist development. The model includes the consideration of chemical reactions between a photoresist and a developer, and takes the developer concentration dependence into account. The model is applied to the design of practical photo-lithography processes to determine development conditions. Through(More)
