Mean-Variance vs. Full-Scale Optimization: Broad Evidence for the UK

In the Full-Scale Optimization approach the complete empirical financial return probability distribution is considered; and the utility maximizing solution is found through numerical optimization. Using a portfolio choice setting of three UK equity indices we identify several utility functions featuring loss aversion and prospect theory; under which Full-Scale Optimization is a substantially bette

Non-LTE calculations of radiative forces for thallium in the atmospheres of HgMn stars

Recent observations by the Goddard High-Resolution Spectrograph on the Rubble Space Telescope have dramatically improved our knowledge of the abundance of the heaviest elements in Mercury-Manganese (HgMn) stars (c.f. Leckrone et al. 1992 and Wahlgren et al. 1995). Explaining the observed abundance and isotope anomalies requires improved calculations of radiatively driven diffusion. We briefly revi

Narratives by district nurses about elder abuse within families.

Twenty-one district nurses (DNs) narrated 44 cases of elder abuse within families. A phenomenological-hermeneutical analysis revealed that the experiences were complex and often included families providing care for an elderly person. The abuse seemed to be related to the inability of one party to meet the care demands required by the elderly, by him- or herself, or by the situation. It also seemed

Polyglandular Autoimmune (PGA) Syndromes and associations to sarcoidosis

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING (Svenska) I en klassisk monografi från 1855 med titel ”On the Constitutional and Local Effects of Disease of the Suprarenal Capsules” beskrev T. Addison det tillstånd som numera bär på hans namn. De 11 beskrivna patienterna innefattade alla huvudorsker till primär binjurebarkssvikt: autoimmunitet- rubbning i kroppens immunförsvar med pPolyglandular Autoimmune (PGA) syndrome type II in idiopathic Addison's disease: In a retrospective study of idiopathic Ad-dison's disease (median age at diagnosis 32.5 years, range 8-62; median observation time 17 years, range 0.5-41), 50% met the criteria for PGA syndrome type II. In PGA syndrome type II, 73% had ATD and 41% had IDDM. The full triad was present in 14%. The sequence of appearance

Criteria and Trade-offs in PID Design

Control design is a rich problem which requires that many issues such as load disturbances and set-point responses, model uncertainty, and measurement noise are taken into account. These issues are discussed for design of PI and PID controllers. The purpose is to give insight into the different criteria and their trade-offs, not to give specific tuning methods.

Analysis of Prefetching Schemes for TV-on-Demand Service

TV-on-Demand service has become one of the most popular Internet applications that continuously attracts higher user interests. With rapidly increasing user demand, the existing network conditions may not be able to ensure low start-up delay of video playback. Prefetching has been broadly investigated to cope with the start-up latency problem which is also known as user perceived latency. In this
