In this thesis, the impact of unknown parameter estimation in the case of the volatility parameter in the Black-Scholes model on hedging is investigated. The objective is to develop a systematic and robust model of hedging to challenge the conventional delta and improved mean-variance hedge, and hopefully improve upon risk assessment values. The proposed algorithms were tested in situations of unc

According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will be dragged towards the disc plane, depositing stars and dark matter into an accreted disc structure. In this work, we utilize the chemodynamical template developed in Ruchti et al. to hunt for accreted stars. We apply t

Objective: To evaluate whether subgroups of patients with no chance of survival can be defined among patients with out-of-hospital cardiac arrest. Patients: Patients in the Swedish cardiac arrest registry who fulfilled the following criteria were surveyed: cardiopulmonary resuscitation (CPR) was attempted; the arrest was not crew witnessed; and patients were found in a non-shockable rhythm. Settin

BackgroundThere is a growing body of evidence indicating that second degree tears cause both short-, and long-term consequences. Very few preventative measures have been found to reduce the incidence of these tears.ObjectiveTo investigate if the use of a perineal protection device during vaginal birth reduces severe perineal tearing (≥grade 2 tear) in primiparous women compared to routine manual p

Cerebral pares (CP) är en diagnos som beskriver en heterogen grupp av individer som alla har någon grad av motorisk funktionsnedsättning. Utöver motorik är andra funktioner ofta också påverkade och komorbiditet (t.ex. epilepsi) samt s.k. ”secondary conditions” (t.ex. smärta) är vanliga. Personer med ryggmärgsbråck (MMC) har också motoriska problem, ofta tillsammans med problem relaterade till neurCerebral palsy (CP) is a medical diagnosis that describes a heterogeneous group of individuals who all have some degree of motor impairment. In addition to motor skills, other functions are often also affected and comorbidity (e.g., epilepsy) and secondary conditions (e.g., pain) are common. Individuals with spina bifida— and often more specifically myelomeningocele (MMC) — also have motor problem

In the year of 2000 the world leaders signed on the Millennium Development Goals, which is eight measurable and time-bound targets to reduce world poverty and promote human rights. In order to achieve these sets of goals by 2015 a lot of foreign aid is being given. The approach towards aid and the MDGs are being criticised by William Easterly. He claims that this approach, which he calls planners
