We present the first implementation of Thread-Level Speculation in combination with Just-in-time compilation. The implementation is done in Google’s V8, a well-known JavaScript engine, and evaluated on 15 popular web application executing on 2, 4, and 8 core computers. Our results show an average speedup of 2.9 on 4 cores, without any JavaScript code modifications. Further, we have found that the

Popular Abstract in Swedish Under 1980-talet blev riskerna med blodtransfusioner alltmer uppenbara. Störst uppmärksamhet väckte ett antal fall med spridning av HIV- (AIDS) smitta, men ännu vanligare var spridning av ett virus som kunde orsaka leverinflammation. Dessa risker är numera nästan helt försvunna men dels kvarstår en oro för spridning av nya, okända virus, dels har det visat sig att blodtBlood loss in major arthroplasty may be abundant and often necessitates blood transfusions. These may transmit disease and entail an immunological burden to the recipient. After trauma and surgery, the fibrinolytic system reacts with a short period of increased activity, followed by a fibrinolytic shut-down. In this thesis we investigated the impact of the early fibrinolytic activation on blood

Popular Abstract in Swedish Denna avhandling handlar om skapandet, användningen och avfärdandet av ett socialt begrepp ? utbrändhet. Avhandlingen är ett försök att förklara den komplexa interaktionen mellan individers handlande och deras sociala miljö samt hur detta producerar ett transient fenomen ? utbrändhetsdiagnosen (en ny olycklig människotyp). Följaktligen handlar det om en analys av ett koThis is a thesis about the genesis, use, and decline of burn-out as a social concept in Sweden. The burn-out concept is treated as social because its classification of people interacts with the people classified. As a consequence of this, burn-out is studied in a dynamic holistic way, as an entirely social system within Swedish society. Hence it follows that the main question examined in the thesi

In about four decades, ion beam analysis (IBA) techniques have evolved to become well established analytical techniques for routine analysis in archaeological, bio-medical, geological and environmental sciences. They basically make use of the different interactions of a high energy ion beam (of few MeV/amu) with the specimen matter so they pressupose the use of a particle accelerator. In laborator

Results from an on-going study of discourse boundary marking involving the Swedish cue word men and its associated local acoustic and lexical parameters are presented

The bio-economy has been put forward as a strategy to increase economic growth without this leading to increased emissions of greenhouse gases. A key concept behind the bio-economy is the increased use of biomass for applications such as the production of bio-based chemicals and materials but also an increased importance for biotechnology and biorefinery systems in the production of these products

This paper analyses the potential biomass supply in the 15 EU countries, 8 new member states and 2 candidate countries (ACC10), plus Belarus and the Ukraine. For this purpose five scenarios were designed to describe the short-, moderate- and long-term potential of biomass-for-energy. Our assessments show that under certain restrictions on land availability, the potential supply of biomass energy

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

A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw

During ascending evacuation in long stairs, there is reason to believe that factors such as fatigue, and change in human behaviour will influence the possibility of satisfactory evacuation and affect the ascending walking speed. Based on these assumption, a 2-year research project was initiated at Lund University. This paper gives a brief description of the project and highlight some initial findi

A complex picture was shown to 12 subjects, and each subject was asked to describe it from memory. Their spoken descriptions were recorded, transcribed and segmented into intonation units (Chafe 1994). The transcripts were then qualitatively analyzed with respect to how the picture had been conceptualized. As a result, two different styles of description could be identified. Perceiving space was d

Detailed particle size distribution of elemental constituents have been determined in the St. Louis aerosol by sampling with cascade impactors for particles >0.25 μm aerodynamic diameter and by analyzing using proton-induced X-ray emission, PIXE, for S, Cl, K, Ca, Ti, Mn, Fe, Zn, Br, and Pb. Two rooftop sites were selected for intensive sampling in industrial and residential locations in St. Louis
