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

We analyse the iterative decoding performance of conventional rate R=1/3 turbo codes, when both code length and number of iterations tend to infinity. To obtain a rigorous bound on the iterative limit, we introduce a two-phase decoding algorithm which can be analyzed asymptotically

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

En text om betydelsen av rummet, makten och motståndet i staden – från modernitet och postmodernitet.

This chapter examines the relationship between individual and organizational identity in PSFs and the significant but tenuous nature of elite identity in this context. The authors identify four main identity-related issues for management control in PSFs: autonomy/conformity tensions, the client conundrum, ambiguity saturation, and intangibility. They explore three main modes of identity-focused co
