this paper addresses the design of control charts for both variable ( x chart) andattribute (u and c charts) quality characteristics, when there is uncertainty about the processparameters or sample data. derived control charts are more flexible than the strict crisp case, dueto the ability of encompassing the effects of vagueness in form of the degree of expert’spresumption. we extend the use o...

statistical process control (spc) charts play a major role in quality control systems, and their correct interpretation leads to discovering probable irregularities and errors of the production system. in this regard, various artificial neural networks have been developed to identify mainly singular patterns of spc charts, while having drawbacks in handling multiple concurrent patterns. in this...

Cross–derivatives are mixed partial derivatives that are obtained by differentiating at most once in every coordinate direction. They are a computational tool in combinatorics and high– dimensional integration. Here we present two methods of computing exact values of all cross– derivatives at a given point both following the general philosophy of automatic differentiation. Implementation detail...

The research summarised here is working towards automatic control systems for cameras, in support of remote meetings. Progress is reported on several fronts: use of active contours to track heads, stereo sound analysis; applying particle filtering to handle both visual and aural clutter; and the use of exemplars for stabilisation of inter-frame matching.

Well-posedness of the considered SC problem: We begin our analysis of the considered SC problem by providing the necessary and sufficient condition for the existence of a correct supervisor. For the systematic characterization of this feasibility condition, we need the following definition: Definition 1. Consider an s-DES G ≡ 〈X × S, Σ ∪ E, δ, (x0, s0)〉, and the supervisor Γ∅ defined by: ∀(x, s...
