From its early days, the academic debate on public goods has focused on discrepancies or trade-offs regarding the provision of public goods on the one hand and private goods on the other. However, both the extension of the public domain and an increasing interdependence in international relations clearly drive the expansion of an agenda in which there are a growing number of cases where public goo
Spatially-Coupled LDPC (SC-LDPC) codes have been recently shown to be very efficient for transmissions over nonergodic channels, in particular over block-fading channels [1]. In fact, it is possible to design a SC-LDPC code with any given code diversity [2]. In this work, we investigate the performance of SC-LDPC codes over block-fading channels, assuming a mismatch (or offset) between the first b
We introduce a mixed-integer optimization model for two-layer IP-over-Flexgrid networks, and present a cost study performed using the CPLEX package for the introduced model. The study concerns a generic German network with 12 nodes and 20 links in the optical layer, and a set of six IP traffic matrices with increasing demand volumes. The optimization assumes a hot-standby mechanism in the optical
Summary of key messages for policy makers • Systemic approach is critical Climate change and natural resource depletion continues to be driven not least by unsustainable levels and patterns of consumption. There is growing recognition that the shift required to achieve sustainable consumption and production is a momentous paradigm shift in Western culture. Due to the holistic nature of shifting c
In industry–academia collaboration projects, there are many issues related to different time horizons in industry and academia. If not adressed upfront, they may hinder collaboration in such projects. We analyze our experiences from a 10 year industry–academia collaboration program, the EASE Industrial Excellence Center in Sweden, and identify issues and feasible practices to overcome the hurdles
The purpose of the study was to evaluate patient relevant outcome after total hip replacement (THR) in patients with primary osteoarthritis (OA). 247 patients >50 years of age with primary hip OA, operated on with THR (Sept1995—Oct1998), were investigated consecutively and prospectively. 68 of the THR were made with hybrid technique. A preoperative radiographic classification was made. Evaluation
Popular AbstractAvhandlingen presenterar, från ett fenomenologiskt perspektiv, interaktionen mellan naturvetenskapens kunskap och annan kunskap, här kallad "vardagskunskap". Utgångspunkten i presentationen är människans existens. Två aspekter av denna lyfts fram som centrala - att människan är kroppsligt utsatt för, berörd av, något hon inte har full kontroll över, samt att hon alltid agerar utifrThe dissertation presents a phenomenological view on the interaction between science knowledge and prescientific knowledge. Drawing on Husserl, Merleau-Ponty and Lévinas the human bodily grounded existence is described, the central feature of this existence being its responsivity to the Other. This responsivity is presented as the starting point for the production of science knowledge, thus making
This paper presents the results of an accuracy study of a deterministic channel model for vehicle-to-vehicle (V2V) communications. Channel simulations obtained from the ray-tracing model developed by TU Braunschweig are compared to data gathered during the DRIVEWAY V2V channel measurement campaign at 5.6 GHz in the city of Lund in summer 2009. The analysis focuses on PDP and channel gains in an ur
There has been extensive research about single link multiple-input multiple-output (MIMO) channels, both simulated and measured, but only few studies have targeted multilink analysis with measured channel data. Hence, in this paper, we analyze the influence of spatial separation of user terminals and the human shadowing effect on the MIMO capacity and to the signal to interference ratio (SIR) in a
Software development organizations are continuously looking for better ways to manage their projects. An emerging approach to achieve this is Inner Source, which refers to the adoption of Open Source development practices within the confines of an organization. With an Inner Source approach, individuals, teams, and departments within an organization can start software projects, very similar to the
This report is produced within the Urban Transition Øresund (UT) project (2011–2014), and it is part of the subtask Collaborative Methods and Tools for Urban Transitions (UT CoMeT). The goal of the UT project is to promote sustainable growth and advance sustainable urban transformation in the Øresund region by gathering municipalities, universities and businesses in cross-border cooperation. The s
In the article funerary rituals observed on early medieval cemeteries of the south-eastern Bornholm are studied and explained from the perspective of theory of practice. Rituals, although sharing certain elements with other types of human practices, are viewed as a special kind of actions due to their formality, fixity and their outcomes. It is argued that the analysis of the funerary rituals prac
The Scandinavian death rituals are expressions of agency (war, negotiations, hunting, and personal attraction), and the outcome of the investigation of depositional practices archaeo- logically. Thus, the death rituals cannot be interpreted as self- explanatory afterlife constructions. The wealth depended on political mobilization and a narration of a sense of belonging. As such, the death rituals
Cooperative content replication and request routing (C2R3) has emerged as a promising technique to enhance the efficiency of content delivery networks (CDN). Most existing approaches to C2R3 focus on efficient bandwidth usage and assume a hierarchical CDN architecture targeted towards the delivery of specific content types (e.g., video). Therefore, C2R3 problem of covering the broad range of conte
Popular Abstract in Swedish Typ 2 diabetes är en av världens vanligaste och snabbast ökande kroniska sjukdomar. Sjukdomen är smygande och ger ofta inledningsvis inte några särskilda symptom. Den kan därigenom förbli oupptäckt under många år. Typ 2 diabetes är dock en allvarlig sjukdom; överdödligheten i hjärt-kärlsjukdomar är fyra gånger högre hos patienter med typ 2 diabetes än hos dem som inte hTo examine cardiovascular risk factors, glycaemic control and survival in patients with type 2 diabetes mellitus (T2DM) treated in primary care, patients with T2DM and a randomised age-stratified sample of men and women aged ≥40 years living in the same community were surveyed 1992-1994. ß–Cell function and insulin resistance were estimated using the Homeostasis Model Assessment (HOMA).
