We extend an existing self-adaptive goal-oriented hp-adaptive Finite Element (FE) strategy to the case of multiple goals. The main idea of this extension is to design a new “quantity of interest” based on the solution of the direct problem and the given multiple goals. We describe an efficient implementation of the multigoal adaptive strategy, and we illustrate its performance with numerical re...

this paper presents a new observer-based control scheme for a class of nonlinear systems. in the proposed method, nonlinear observer and twisting algorithm controller are employed to realize a sensor-less control strategy for complex systems which makes use of non measurable process information instead of installing as many sensors as possible. due to lack of availability of the complex system ...

This paper explores the co-relational process activities of information technology and systems (IT/IS) and business strategy alignment. The notion of “process” as being strategy and strategic alignment has been observed but not examined. Organizations are both complex and adaptive, and these attributes create significant challenges for managers when assessing strategic requirements. A need exis...
