It is well-known that there exists a critical control weighting parameter which results in an unstable controller design if the uncontrolled system is unstable or nonminimum phase and a single stage cost functional is used. The purpose of this note is to show that the determination of this parameter reduces to solving a root-locus problem.

This paper seeks to investigate how tourism marketing projects are used in order to promote cooperation within developing cross-border regions in Northern Europe.

In today’s highly competitive market place it is of great importance for companies to deliver reliable products while decreasing the development time and costs. The time to market is a driving force for many companies, and throughout the engineering design process as well as the manufacturing process, the focus is on finding timesaving actions. However, the search for timesaving actions will most

Although a substantial body of theoretical as well as empirical work emphasizes the role of the mass media in constructing what could serve as a political public sphere at the European level, strikingly little is known, in qualitative terms, about opinion-making journalists’ underlying views and orientations on the European integration process. The point of departure in the present paper is that o

This paper reflects and analyzes upon a research and pedagocial development project “Gender perspectives on university education and academic disciplines - a pedagogic project for the development of teaching – an intersectional approach (financed by the Swediah Council for Renewal of Higher Education). The project aims to further develop pedagogical models for the inclusion and integration of a “g

In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. One of the most significant bottlenecks for deployment of solar heating

The development of MIMO over-the-air (OTA) test methodology is an ongoing activity in 3GPP RAN4, CTIA and EU COST Action 2100. In this paper, the focus is on the anechoic chamber approach, which uses a uniform circular array of probe antennas to replicate directional channels for the device under test (DUT) at the array center. In particular, we study in simulation the complexity requirements of i

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. About two-fifths of the world population can be categorized as poor. Poverty is a trap because children born to poor parents are likely to grow up to be poor adults. In recent years, a poverty reduction approach that combines business development with povert

To compete on a globalized market companies need to constantly improve the performance in their manufacturing systems. Production performance measures can be used for different purposes, by practitioners they are commonly used for follow-up and reporting purposes. Two of the most commonly used performance measures are Overall Equipment Efficiency (OEE) and productivity. Between these two productiv

Isotropic chiral media can be modeled in several ways. We show that when realizing such a medium from spiral inclusions with real permittivities and permeabilities in a periodic structure, a modified Drude-Born-Fedorov model is obtained. This model equals the original Born model for small wave vectors, but the strength of the chirality depends on the propagation direction. The effective parameters
