An experimental technique based on double planar laser-induced fluorescence (PLIF/PLIF) using two tracers for the measurement of the local concentration of liquid phase in a two-phase system with large bubbles is presented. Fluorescence emission intensity calibration was performed to validate the use of the laser and tracer combinations at each point in the images on two CCD cameras, separately. B

This paper deals with optimal load balancing in telecommunication networks. For a capacitated telecommunications network with single path routing and an estimated traffic demand matrix, we wish to determine the routing paths aiming at min-max optimization of link loads. To solve this problem, we propose a column (path) generation based heuristic. In the first step, we use column generation to solv

Popular Abstract in Swedish Ur ett utvecklingsbiologiskt perspektiv är ångest en primär emotion som är mer eller mindre närvarande hos oss alla. Inom vissa gränser anses en individs vanemässiga ångestnivå vara ett centralt personlighetsdrag av betydelse för individens förmåga att känna oro, uppfatta sin omvärld, och vara känslig för negativa stimuli. Som personlighetsdrag har ångest ofta rapporterThis thesis deals with the problem of interpreting test scores. The intention has been to explore and elucidate the effects of trait anxiety on test scores that have been obtained in applied research settings. Paper I showed that different relationships between personality traits and cognitive functioning emerged in a group of men with solvent induced chronic toxic encephalopathy (TE; N=57) compa

This paper is a component of a three-year empirical study of gaming moms undertaken with the aim to modulate the conventional constructions of gamer identities and examine the contested status of gaming in everyday life. It presents samples of mothers in gaming discourse – from TV, Music-video, forums, and ads. Mothers have been largely invisible in popular gaming discourse or formulaically portra

Ley crops can be grown to provide a substrate for biogas vehicle-fuel production on a range of soils including marginal land. According to EU regulations, such biofuel currently has to achieve an emission reduction of 35%, but tightened goals of 50 and 60% will come into effect as early as 2017. In two field trials (one on marginal soil, one on productive soil) ley crop mixtures were tested and th

We deal with the important applicative problem of distributed cameras calibration. We model a network of N cameras as an undirected graph in which communicating cameras can measure their relative orientation in a noisy way. These measures can be used in order to minimize a suitable cost function. The shape of this cost function depends on a vector of integers K. We propose two algorithms which in

Popular Abstract in Swedish I syfte att upprätthålla en optimal miljö för alla kroppens celler har högre stående djur utvecklat blodcirkulationen genom vilken syre- och andra närings ämnen transporteras till vävnader via artärer och de mindre arteriolerna, medan slaggprodukter förs bort med venerna. Utbytet av näringsämnen och slaggprodukter mellan blod och vävnad sker genom kärlväggen i kroppens Disturbances in microvascular function may be important for tissue damage in many disease states. Prostacyclin, a substance produced by endothelial cells, is important for the maintenance of normal vascular homeostasis and is a potential drug for treatment of microvascular dysfunction, but indications and optimal dosage remains to be established. In the present thesis we evaluated the capillary fi

beskrivning: Botanisten och författaren Bengt Lidforss (1868-1913) var sin tids mest kontroversielle akademiker och tidningsskribent. Han var den förste universitetsläraren i Sverige som anslöt sig till socialdemokratin, han ansågs sakna moral och vara en ungdomens förförare, han debatterade glatt och framgångsrikt med biskopar och rektorer, och han skrev lysande, framsynt litteraturkritik och fol

Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. The first chapters briefly explain the optics of solar energy concentrators. The theoreti
