Popular Abstract in Swedish Avhandlingen är uppdelad i två delar. Del I analyserar kapacitet för linjära modulationssystem med en bärvåg. Inom dessa system så skickas bitarna som en sekvens av pulser, där varje puls representerar en bit. När pulserna lanseras över kommunikationskanalen, så kommer de utsättas för reflektioner, interferens, och andra störningar. Kapaciteten är en övre gräns på antalThis thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. It depends on the underlying pulse shape in a linear modulated signal and also the signaling rate, the rate at whic

This thesis consists of three empirical studies on the effects of institutions, broadly conceived, on economic outcomes. The first study tests for evidence of causal relationships between provincial quality of governance and economic growth rates in reform-era China, 1985–2005. Improvements in governance are found to be significantly predicted by lagged economic growth rates, while economic growth

Moderna mobiltelefoner är ofta utrustade med olika sensorer som används flitigt bland annat för spel, men som också kan användas i fysikundervisningen. Här analayserar vi accelerometer- och rotationsdata från en iPhone4 som tagits med (i en stängd ficka) i åkattraktionen Lilla Lots på Liseberg.

The reliability of official registers of diagnosis depends on proper adherence to guidelines for diagnosis and diagnosis coding. Such guidelines for severe sepsis and septic shock have changed over the years, reflecting improved knowledge of these serious conditions. In order to investigate the compliance to current Swedish guidelines for diagnosis and coding of severe sepsis and septic shock, we

Asymptotic iterative decoding performance is analyzed for several classes of iteratively decodable codes when the block length of the codes N and the number of iterations I go to infinity. Three classes of codes are considered. These are Gallager's regular low-density parity-check (LDPC) codes, Tanner's generalized LDPC (GLDPC) codes, and the turbo codes due to Berrou et al. It is proved that ther

Artikel gällande handläggning av yrsel på akutmottagningen.The majority of patients who present to the Emergency Department with vertigo suffer from benign conditions. However, a few percent of these patients have life-threatening conditions, such as a cerebellar stroke. The HINTS clinical decision rule (Head-Impulse test, Nystagmus, Test-of-Skew) allows the physician to identify patients with an acute vestibular syndrome of central origin. HINTS is more

Stochastic optimal power flow can provide the system operator with adequate strategies for controlling the power flow to maintain secure operation under stochastic parameter variations. One limitation of stochastic optimal power flow has been that only limits on lineflows have been used as stability constraints. In many systems voltage stability and small-signal stability also play an important role i
