Product codes, due to their relatively large minimum distance, are often seen as a natural solution for applications requiring low error floors. In this paper, we show by means of an ensemble weight enumerator analysis that the minimum distance multiplicities of product codes are much higher than those obtainable by other generalized LDPC (GLDPC) constructions employing the same component codes. W

Cross-cultural comparable data collected in several Romance and Scandinavian languages with the help of a series of tasks inspired by Fehr and Rusell’s prototype approach to emotions are analyzed from a perspective that goes beyond the interpretation of prototype theory and aligns with the theory-based approaches to categorization (cfr. the seminal paper by Murphy and Medin 1985). Due to space lim

Popular Abstract in Swedish Denna studie fokuserar på reproduktionskostnader och de energetiska taktiker som en reproducerande individ kan utnyttja för att tillfredsställa det ökade behovet av energi och näring under reproduktionen. Reproduktionskostnader har traditionellt definierats som reduktioner av den framtida potentiella produktionen av avkomma, orsakade av en nuvarande reproduktiv investerThis study focuses on various aspects of costs of reproduction and the evolution of energetic breeding tactics. It emphasizes the distinction between demographic costs of reproduction expressed already before current offspring have reached independence (prebreeding costs), and costs expressed only after offspring independence (postbreeding costs). Prebreeding costs have only rarely been appreciate

A novel method for learning characteristic decision trees is applied to the problem of learning the decision mechanism of coin-sorting machines. Decision trees constructed by ID3-like algorithms are unable to detect instances of categories not present in the set of training examples. Instead of being rejected, such instances are assigned to one of the classes actually present in the training set.

Popular Abstract in Swedish Diabetes mellitus är en kronisk sjukdom som orsakas av en oförmåga att bilda och/eller känna av insulinets effekt i vävnaderna, vilket leder till förhöjda blodsockervärden. Diabetes som debuterar i unga år och där insulinproduktionen oftast är upphävd klassas som typ 1 diabetes. Typ 2 diabetes debuterar senare i livet och här finns olika grader av insulinproduktion kvarDiabetic retinopathy is a common complication to diabetes mellitus and is still a major cause of impaired vision in the Western world. The aim of the present study was to identify medical risk factors influencing the development and progression of retinopathy in type 1 diabetic patients, and to investigate the effects of laser treatment on visual acuity and glare. Although the development of sigh

It is expected that, in the future, gas turbines will be operated on gaseous fuels currently unutilized. The ability to predict the range of feasible fuels, and the extent to which existing turbines must be modified to accommodate these fuels, rests on the nature of these fuels in the combustion environment. Understanding the combustion behavior is aided by investigation of syngases of similar com

This chapter discusses the consequences for a long-term sick individual when rehabiliation back to work fails and where she is objectified in a double-sided process. She is objectified first as a "sick body" before the medical authorities charged with producing health. Second she is objectified in terms of her rehabilitation to work, when given the responsibility to find the "healthy" part of her

Use of Fire Safety Engineering (FSE) has increased substantially during the last decades. In the beginning fire safety engineering was mainly used for fire performance based design of buildings but recently new areas such as marine transport have appeared as new applications for fire safety engineering. So on one hand we have the increasing use of FSE. On the other hand we have the introduction of

Popular Abstract in Swedish En av tio kvinnor utvecklar bröstcancer någon gång under sin livstid, vilket innebär att bröstcancer är den vanligaste cancertypen hos kvinnor idag. De vanligaste behandlingarna av bröstcancer är kirurgi, radioterapi, kemoterapi, hormonterapi och immunoterapi. Nackdelen med dessa behandlingsmetoder är att de flesta av dem ger allvarliga bieffekter hos patienten. Därför Apoptosis is a defined process for cells to commit suicide through a set of biochemical and morphological cell changes. Activated apoptotic signals converge on the mitochondria, leading to permeabilization of mitochondrial membranes and release of different apoptosis regulatory proteins into the cytosol. With my studies I wanted to investigate the importance of polyamines in the regulation of apop

Three potential filter materials, granular activated carbon, bone meal and iron fines, were evaluated for treatment of heavy metal contaminated landfill leachate. All materials could sorb some metals to a high extent; more than 90 % of some metals were removed. However, all filters suffered from the drawback of releasing unwanted substances. Geochemical modelling was used to elucidate sorption mec

The article presents the results of a quantitative study of Norwegian and Swedish newspaper articles from 2000 and 2001. The study includes a limited content analysis of the newspaper articles, and a comparison to statistical data on migration.
