Model Reduction of Spatially Distributed Systems Using Coprime Factors and Semidefinite Programming

In this paper an order reduction method for spatially distributed models is presented. Such systems may be modeled as two nodes interacting with each other through feedback. A model of one of the nodes reduced in such a way, that the closed loop performance is approximated. The method exploits a coprime factor description of the closed loop model and semidefinite programming. The method is related

Passing the buck: transferring unanticipated purchasing costs to suppliers and customers

Unanticipated procurement costs due to changes in input factors’ market prices and exchange rates are an increasing issue for manufacturers. A popular strategy is transferring these price increases to the supply chain. Based on 12 interviews and a follow-up study, we identified the main enablers for manufacturers to do so.

The Law and the Insane: Cases of Literary Censorship Involving the Mentally Insane During the Qianlong Reign

In a study on the problems of censorship and interpretation from 1984, (Censorship and Interpretation; The Conditions of Reading and Writing in Early Modern England), Annabel Patterson states that British authors of the seventeenth century often used the shelter of ambiguity as a protection from the threat of censorship. But as the text had to be understood by the intended readers, Patterson argue
