We give a concise review and extension of S-procedure that is an instrumental tool in control theory and robust optimization analysis. We also discuss the approximate S-Lemma as well as its applications in robust optimization. Copyright Springer-Verlag 2006

The fundamental problem for any scheme of water management that tries to maximise welfare across a river system is that of determining the optimal allocation at every point. The problem cannot, in general, be avoided by trading water rights because the price will not account for the effect of...

How can service firms manage displays of frontline service employees most effectively? Building on organizational control theory, this research develops a typology of employee display controls for routine service delivery that distinguishes three formal controls (aesthetic, emotional, and...

Cross compliance has been introduced in the EU partly to improve compliance with pre-existing EU legislation in the Member States. Considerable effort has been put into implementing this instrument and the corresponding control systems. This presents an opportunity to assess factors for an...

Managing highly skilled employees is extremely complex because of the need to balance the costs and time lags associated with their training against the need to meet demand as quickly as possible. Unlike previous approaches to this problem in the staffing literature, this paper develops an...

Expenditure Management is critical to effective public service delivery, especially at the local government level. Leveraging on information systems to aid in expenditure management is viewed as an effective method in bringing about transparency and accountability in this process. Past research...

This paper uses a control theory approach to analyse the collectively optimal rate of extraction along a river system and constructs a bidding mechanism that would produce the required prices at each point. It also analyses some characteristics of this mechanism. This approach brings some new...
