An algorithm to compute the Radiation center of an antenna based on the Spherical wave expansion is introduced. The method is based on the angular momentum vector that is uniquely defined for any antenna far field pattern. The radiation center is defined as the unique point where the magnitude of the angular momentum is minimized with respect to translations of the far field. This corresponds to m
To increase the number of services and applications in the telecommunication networks a new service architecture has been proposed and specified. The consortia that initiated the new service architecture is called Parlay. Since then, there has been a continued development and 3GPP the standardization group for 3G networks, is now cooperating with Parlay. 3GPP and Parlay are together specifying the

The purposes of this study were to ascertain whether Swedish construction companies measure the impact of their quality systems (such as ISO 9000) and, if so, whether the ‘balanced scorecard’ approach is a useful technique as a measure of performance. The balanced scorecard approach requires each organization to look at itself from four different perspectives to provide a more comprehensive view o
Lipid oxidation is a major problem in muscle foods, leading to a loss in quality and nutritional value. It occurs in raw meat but is usually more pronounced in cooked meat. Since the demands of consumers for ready-to-eat foods have increased, the control of off-flavour in cooked meat is an important industrial problem. One way of minimising the development of lipid oxidation is to optimise the act
Mysticism can be regarded as an integral element of religion. It includes both a way of life and a direct consciousness of the presence of God. Broadly defined as such, one can encounter mystical dimensions within all religions of the world. In order to alter consciousness, mystics in different traditions use a variety of techniques – different types of meditation, visualisation, repetitive prayer
The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. The two isolated N-terminal modules were p
