Arbete, stress och hälsa

Problemområdet arbetsrelaterad stress har inte någon entydig ämnesteoretisk hemvist eller definition. Trots områdets vaga konturer måste forskare, praktiker och lekmän ofta förhålla sig till arbetsrelaterad stress. Exempelvis är diskussionen om stress och stressrelaterade tillstånd vanligt förekommande i medierna, bland politiker och hos allmänheten. Det är dock ovanligt att sjukdomar som misstänk

Improving regression testing transparency and efficiency with history-based prioritization – an industrial case study

Abstract—Background: History based regression testing was proposed as a basis for automating regression test selection, for the purpose of improving transparency and test efficiency, at the function test level in a large scale software development organization. Aim: The study aims at investigating the current manual regression testing process as well as adopting, implementing and evaluating the ef

The Impact of Stellar Collisions in the Galactic Center

We consider whether stellar collisions can explain the observed depletion of red giants in the Galactic center. We model the stellar population with two different IMFs: 1) the Miller-Scalo and 2) a much flatter IMF. In the former case, low-mass main-sequence stars dominate the population, and collisions are unable to remove red giants out to 0.4 pc although brighter red giants much closer in may b

Predictions of Enhanced Heat Transfer of an Internal Blade Tip-Wall with Hemishperical Dimples or Protrusions

The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di

Hotad idyll. Berättelser om svenskt folkhem och kallt krig

I "Hotad idyll" förenas litteraturvetenskapens intressen för texter med historievetenskapens intresse för bredare sammanhang för att nå en större förståelse av historiska skeenden. I fokus står de föreställningar som präglade den vardagliga idyllen i 1950- och 1960-talens Sverige.

Sign-Bit based architecture for OFDM acquisition for multiple-standards

This paper presents a hardware mapping of an auto-correlator for Orthogonal Frequency Division Multiplexing stage for three radio standards: LTE, DVB-H, and IEEE 802.11n. Hardware cost is minimized by using only the sign bit in the autocorrelation function. The frequency offset estimation procedure is dramatically simplified by reducing the phase of the envelope to pi/2 resolution, which in turn r

Clinical Electrocochleography in Menière´s disease

Popular Abstract in Swedish Elektrocochleografi (ECoG) är en metod som mäter de elektriska signaler som uppstår i innerörat när örat stimuleras med ljud. Signalerna uppstår i snäckans sinnesceller, de så kallade hårcellerna, och i nervcellerna som utgår från snäckan. Snäckan är det organ som omvandlar ljudets mekaniska energi till elektriska signaler i hörselnerven. Hörselnerven förmedlar signalerElectrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. The aim of the present thesis was to investigate the value of transtympanic (TT) ECoG in the clinical diagnosis and management of Menière´s disease. The tr

Causal Truthmaking

This paper provides an outline of a theory of causal truthmaking according to which contingent truths are made true by causal facts and dispositional mechanisms.
