This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. This includes thorough investigation of central components that influence Turbo code performances, such as the constituent encoders and the interleaver, as well as the procedure of

Recent climate change has sparked an interest in the timing of biological events, which is a general problem in life-history evolution. Reproduction in many organisms breeding in seasonal environments, e. g. migratory birds, is dependent on the exploitation of a short but rich food supply. If the seasonal timing of the food peak advances owing to climate change, then one would expect the bird to t

Purpose. To determine the potential application of high-intensity focused ultrasound for the minimally invasive treatment of herniated intervertebral discs by developing a probe that produces sufficiently high temperature locally to shrink collagen fibers (65-75 degrees C). Materials and Methods. A 5-mm ultrasound probe was produced with a geometric focal length of 15 mm. The probe produced 2.5 W

Artikeln behandlar muralmålningarna i Borgmästarehuset i Ystad, som 1907 demonterades och flyttades till museiområdet i staden. De kan av förfataren med hjälp av fotografisk dokumentation beläggas på samma plats före rivningen, och de dateras med hjälp av träsnitt som kan ha fungerat som förlagor till 1500-talets senare del. Deras ikonografi, kring Kristi passionshistoria, och deras funktion i en

Pseudoneurological symptoms (i.e., conversion disorder), historically subsumed within the "hysteria" concept alongside phenomena such as psychogenic amnesia and multiple personality disorder have been classified as somatoform disorders since DSM-III. Since then, there have been repeated calls to reclassify conversion disorder with the dissociative disorders, as in ICD-10. The authors review issues

The way relationships between symbols and thoughts are created is a general problem in learning, mainly described as "how students' learn to mean". This general problem raises some basic questions concerning how students' relate understanding to words used in learning. The present research provides an alternative perspective on the relationship between thought and language derived from the phenome

Aims: To explore the precision of task based estimates of upper arm elevation in three occupational groups, compared to direct measurements of job exposure. Methods: Male machinists (n = 26), car mechanics ( n = 23), and house painters ( n = 23) were studied. Whole day recordings of upper arm elevation were obtained for four consecutive working days, and associated task information was collected i

Swedish universities and government authorities are increasingly making their publications electronically available on the World Wide Web, either on web sites or in local systems, so called institutional repositories. Standardisation of metadata is a way of increasing access to these publications. Tools and workflows are also being developed to secure long term preservation and access. On 18 Octob

In this thesis I offer a unified syntactic account of the small clauses involved in Swedish object-with-infinitive constructions (ECM), object predicative constructions and absolute constructions. In the present framework, this similarity is conceptually appealing and is also supported by empirical data. My account extends to other types of small clauses as well. I claim that small clauses are pro

Abstract in French Cet article est basé sur l’analyse de deux corpus de français écrit langue étrangère par des apprenants suédois ; l’un transversal et l’autre longitudinal. Les deux corpus permettent des approches différentes, l’une de caractère linguistique mettant l’accent sur le profil développemental de l’accord en nombre ; l’autre plus cognitive analysant les aspects des connaissances expliThis article is based on an analysis of two corpora in French as a foreign language by Swedish learners; one cross-sectional and the other longitudinal. These two corpora lent themselves to different approaches: a linguistic approach which stressed the developmental profile of agreement in number; and a more cognitive approach which analyzed various aspects of explicit and implicit knowledge in th
