One of the most important aspects of the marriage legislation in medieval canon law is the doctrine of free choice. According to this doctrine, established by pope Alexander III in the second half of the twelfth century, the validity of a marriage depended solely on the freely given consent of the parties. No one could legally force a couple to marry if they did not freely consent to do so. In par
We predict the formation of giant vortices in quasi-two-dimensional quantum dots at high magnetic fields, i.e., in rapidly rotating electron droplets. Our numerical results for quantum dots confined by a flat, anharmonic potential show ground states where vortices are accumulated in the center of the dot, thereby leading to large cores in the electron and current densities. The phenomenon is analo
This thesis is concerned with the design of efficient parallel algorithms for some optimization graph problems. A subset S of vertices or edges in a graph G is said to be maximum with respect to a property if, among all the subsets of G having this property, S is one having the largest cardinality. Set S is said to be maximal with respect to a property, if it is not a proper subset of another set
Popular Abstract in Swedish En fråga inom biologin som länge intresserat forskare är varför det ena könet hos många arter har så väl utvecklade ornament. Till dessa så kallade sekundära könskaraktärer (primära könskaraktärer är de som används vid själva fortplantningen) räknas till exempel påfåglars stjärtplymer och hönsfåglars kammar och sporrar. Dessa ornament förekommer oftast hos hanar och i pFemales often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. Several mechanisms that link the expression of sexual ornaments to genetic quality have been suggested. Many models assume that this link is individu
In this paper, multiple-input multiple-output (MIMO) channel measurements in an outdoor micro-cell environment are used to study the effect of base-station (BS) inter-element spacing on multi-user MIMO signal separation. Users with two dual-polarized patch antennas at the mobile station (MS), and four equally-spaced dual-polarized patch antennas at the BS are considered. At the BS, the inter-eleme
The convergence of the Internet and Telecommunication Architectures is a key issue in today’s telecommunication world. It is foreseen that future versions of UMTS will be all-IP based, and therefore the interest in this area is increasing. The focus in this paper is to show how to access IN-services from the Internet and other IP-based networks. Previous research of the interworking between PSTN a
Förutom att vara en uppskattning av Håkan Lundström är detta en bok av intresse för alla som funderar i konstnärliga termer och framför allt i en akademisk miljö. Boken består av en mosaik av idéer om allt möjligtsom ryms under det konstnärliga idéparaplyet och som har något slags anknytning till festföremålet. Utgångspunkten är drongo-fågeln som är en metafor för längtan i kammudiktningen, som haApart from appealing to those who know and appreciate Håkan, this book is likely to interest the artistically inclined, particularly those in an academic environment. It is a mosaic of texts, more than a mere memorial, that allows us to accompany Håkan on a journey to many of the places contained under the artistic umbrella, especially those which happen to have a more intimate connection with our
In the present study, the effects of a single rib on the local heat transfer around a bluff body are examined by using the steady state liquid crystal technique. By varying the spacing between the bluff body and the rib, the interaction between the rib and the bluff body can be controlled. The bluff body is oriented vertically towards the flow direction and spans the whole height of the channel. T
This article concerns the co-evolution of hominin cooperation, communication and cognition. Certain hominin ecologies seem to have relied on cognitive foresight. The capacity of planning for future needs, combined with more developed cooperative skills, opened up the cognitive niche of cooperation towards future goals. Such cooperation requires complex intersubjectivity (theory of mind). We analyz
