In this paper a general method of constructing control charts for preliminary analysis of individual observations is presented, which is based on recursive score residuals. A simulation study shows that certain implementations of these charts are highly effective in detecting assignable causes.

An approach for eigenvalue assignment in linear descriptor systems via output feedback is proposed. Sufficient conditions in order that a given set of eigenvalues is assignable are established. Parametric form of the desired output feedback gain matrix is also given. The approach assigns the full number of generalised eigenvalues, guarantees the closed-loop regularity and overcomes the defects ...

Increased competition is making it difficult to distinguish products solely by attributes, creating room for cause-related marketing. In this study with a sample of 322 university students, we evaluated the changes in consumer attitudes toward cause and brand as consequences of Cause Brand Alliance (CBA), by using the product category as moderator. Four popular brands from two product categorie...

We present various comments on a question about systems over rings posed in a recent note by Sharma, proving that a ring R is pole-assignable if and only if, for every reachable system (F,G), G contains a rank-one summand of the state space. We also provide a generalization to deal with dynamic feedback.

the hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. recently, the variable sampling intervals (vsi) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been pro...

In this paper, the fully actuated system (FAS) approaches for continuous-time systems with time-varying state delays and a constant input delay are presented. Two types of high-order FASs proposed: single-order both multi-order delays. Controllers time-delay designed based on full-actuation features systems. Unlike case only, prediction scheme is required constructed Similar to linear closed-lo...

It has been shown that a generic -tuple of input output dynamical systems is simultaneously stabilizable (pole assignable) if + and the McMillian degrees of the systems are not too different. This result improves the currently known upper bound: max( ) on the number of plants. In the case max( ), an upper bound on the degree of the simultaneous pole assigning compensator has also been derived, ...

A graph G is R-role assignable if there is a locally surjective homomorphism from G to R, i.e. a vertex mapping r : VG → VR, such that the neighborhood relation is preserved: r(NG(u)) = NR(r(u)). Kristiansen and Telle conjectured that the decision problem whether such a mapping exists is an NP-complete problem for any connected graph R on at least three vertices. In this paper we prove the conj...
