This paper considers a class of control problems where there is a need to find switching-sequences between different linear systems, as well as linear control laws, to minimize some quadratic cost function. An algorithm to optimize the switching sequences for a class of switched linear problems is presented. The algorithm searches for solutions which are arbitrarily close to optimal finding the op

The history of the Royal Physiographic Society in Lund during the years 1772-2006 is described.

Description and assessment of attitudes among young women--all living in villages near Shiraz, Iran--toward family, education, employment, marriage, gender relations, religion, politics, and US-Iran relations. Data derived from author's interviews in period 2001-2005.

This paper will address the effects of mixing low-calorific fuel in to a natural gas fuelled large size combined cycle plant. Three different biofuels are tested namely; air blown gasification gas, indirect gasification gas and digestion gas. Simulations have been performed from 0-100% biofuel natural gas mixtures. The biofuel impacts on the full cycle performance are discussed. Some more in-depth

In 1637 the Swedish Crown, encouraged by Dutch merchants, developed a plan to establish a colonial outpost in America to tap into profitable tobacco and beaver pelt trade. The same year the first cargo ships left Sweden and sailed westwards to claim their piece of America along the Delaware River. Although in many ways unsuccessful and short-lived (the colony collapsed in 1656), New Sweden became

This is a thesis on the Swedish writer Vilhelm Moberg (1898–1973) and his renowned novel cycle about Swedish emigrants to the U.S.: Utvandrarna (1949), Invandrarna (1952), Nybyggarna (1956) and Sista brevet till Sverige (1959). The novels, set in the mid 19th century, describe Swedish emigration to North America through the main characters of Karl Oskar, Kristina, Ulrika and Robert from the parish

In this article the author examines varieties of resource-conflicts between peasants and lords regarding woods and forests in Scania, Denmark, during the late 15th and early 16th centuries. Important results are among others that the wood resource was very disputed this period due to an increasing population pressure as well as an expansive landed aristocracy. The patterns of conflict were often c

Salutogenetic factors (Antonovsky, 1987) at rehabilitation sections in Swedish Social Insurance offices were investigated in 2 studies. Study 1 (N=158) surveyed creative/stagnated climate (Ekvall, 1988), leadership of immediate superior (Ekvall&Arvonen, 1991), and sense of coherence (Antonovsky, 1993), here modified for the work place (W-SOC). A multiple regression (p< .001) showed that creati

This study investigated the effect of experimental task on the processing of Central Swedish word accents. Both reaction times and response times were included as behavioural measures in a word accent/suffix (mis-)match paradigm. Results support the hypothesis that Accent 2 is associated with a heavier lexical functional load as compared to Accent 1. This effect was found to be relatively task-ind

To investigate defense mechanisms, repressors (n= 14), highly anxious (n = 37) and low anxious (n = 7) groups were tested with the Meta Contrast Technique (Smith, Johnson, Almgren & Johanson, 2001). The division into repressors and anxiety groups was made on a larger group (N = 140), which was also investigated with respect to experienced access to preconscious processes, here operationalized
