Routing of elastic traffic in the Internet should be fair in terms of bandwidth allocated to individual traffic demands. One fairness principle that can be applied is called max-min fairness (MMF) and requires that the worst bandwidth allocation is maximized and the solution is then extended with maximization of the second worst allocation, the third one, and so on. In this paper we discuss soluti

The quality in the exchange of technical data in the extended enterprise is mainly defined by the geometrical consistence of the transferred information. Methods and definitions that cover the remaining aspects of data exchange have to be developed. This article discusses a new standardization effort for the exchange management of technical data (ENGDAT version 3) and provides a methodology as wel

Urinary tract infection is the most common infection in man. P fimbriae are virulence factors of uro-pathogenic Escherichia coli. They are expressed by 70-90 % of acute pyelonephritis isolates and up to 100% of the most virulent isolates that cause bacteremia. This thesis concerns the interaction between P fimbriae and the urinary tract mucosa, and the host receptors involved in fimbrial recognit

Reference attribute grammars (RAGs) can be used to express semantics as super-imposed graphs on top of abstract syntax trees (ASTs). A RAG-based AST can be used as the in-memory model providing semantic information for software language tools such as compilers, refactoring tools, and meta- modeling tools. RAG performance is based on dynamic attribute evaluation with caching. Caching all attributes

In this work, we study a flow restoration based network design problem where we assume the knowledge of possible failure situations. We use the idea of a situation disjoint path pair (nominal path, backup path) which are constructed in such a way that at least one of them is operational in any given failure situation for a flow. We present an approximate linear programming formulation of the probl

Popular Abstract in Swedish Det svenska samhället har förändrats mycket genom invandring under de senaste årtiondena. Många barn i Sverige har idag ett annat modersmål än svenska. De flesta barn tillägnar sig svenska utan problem, medan så inte är fallet för vissa barn. Dessa skillnader har diskuterats, och olika förklaringar till detta har framhållits, till exempel bristfällig exponering för svenThe aim of this thesis was to provide both epidemiological and linguistic data on bilingual children with language impairment (LI), since few data on this group exist. Data from 438 bilingual and monolingual children, referred over a period of 12 months, were compared in the first epidemiological study. The results showed that the bilingual children with suspected LI were referred significantly l

In this article, we describe a system that classifies relations between entities extracted from an image. We started from the idea that we could utilize lexical and semantic information from text associated with the image, such as captions or surrounding text, rather than just the geometric and visual characteristics of the entities found in the image. We collected a corpus of images from Wikipedi

We show that for any ε > 0, a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(nω + n2+ε), where ω is the exponent of fastest matrix multiplication algorithm. By the currently best bound on ω, the running time of our algorithm is O(n2.376). Our algorithm substantially improves the previous time-bounds for this problem recen

On 2 November 1994, the Human Rights Committee adopted General Comment No. 24 (52), which was clearly provoked by the great number of reservations deposited by States to the International Covenant on Civil and Political Rights (ICCPR) and its two Optional Protocols. In this decision, the Committee states its opinion on a variety of matters. All relate to the permissibility and effect of reservatio
