Regularization of the limiting optimal controller in robust stabilization

In this paper, we consider the problem of robust optimization for a system with uncertainty of rank one. The main result is the regularization of the limiting optimal controller. We will give the method to obtain the low order suboptimal controller that provides the stability margin as close to the optimal one as we wish. The method is illustrated by some scalar examples.

The condition that lost its name but gained a treatment: : experiences of depression and antidepressant use in a neoliberal context

This paper analyses experiences of depression and antidepressant use within a neoliberal society. The paper is based on interviews with mainly women using antidepressants in Sweden and makes use of the post-political as conceptualized by Chantal Mouffe as a framework. I find that depression is reduced to a state, a diagnosis. In comparing with Nancy Friedan who gave the depression and despair Amer

Lifetime measurements of Metastable States in Fe+

The lifetime of two metastable levels in Fe+ has been measured by laser probing of a stored ion beam. In the dense spectrum of Fe+, the metastable levels a 6S5/2 and b 4D7/2 were selected and their lifetimes were determined to be 230+/-30 and 530+/-30 ms, respectively. The lifetimes are compared with previous theoretical results. Metastable lifetime measurements of Fe+ are of great importance for

On the Application of Elastic Scattering Analysis as a Complement to PIXE for the Determination of Light Elements in Thin Aerosol Samples

The potential of elemental analysis of light elements by measuring elastically scattered particles as a complement to PIXE (Particle Induced X-ray Emission analysis), when using a 3 MV electrostatic tandem accelerator is discussed. The discussion is based on protons and He ions with energies suitable for PIXE. Some experimental results of scattering yields are included.

Transferring technology to developing countries

In 2003/2004 the Masters of European Affairs Programme looked at IPRs and the relationship between developed and developing countries as it pertained to technology transfer, and specifically the TRIPS Agreement. They addressed three crucial issues: Can the rules on international exhaustion of IPR provide the means to transfer essential medicines to developing countries? Having determined that exha

Urkund - Utbildande eller endast avskräckande?

Detta arbete genomför en empirisk studie för att mäta en eventuell lärande effekt hos studenterna från användandet av textigenkänningsverktyget Urkund. Datamaterialet utgör ett obundet slumpmässigt urval på 100st uppsatser från de totalt 390 magister uppsatser som skrivits vid nationalekonomiska institutionen vid Lunds universitet från 2005‐2010. Resultaten visar att plagieringsindexet, som skapas

A Synthesis Method for Static Anti-Windup Compensators

Synthesis of static anti-windup compensators is considered. LMIconditions are established for stability and performance analysis of the closedloop system. The performance criterion describes the servo problem forthe resulting closed-loop piecewise linear system. The synthesisof the anti-windup compensators will be given by some bilinear matrix inequalities.
