Noise computation of a turbo-engine jet exhaust based on LES and lighthill's acoustic analogy
Increasing noise regulations at urban airports force jet engine manufactures to develop and build more quiet engines. Over recent years, a significant reduction in fan and mechanical noise has been achieved. However, the jet exhaust is the principal source of noise. The acoustical field that is generated by a turboengine jet exhaust running near the ground level is considered. The full equations o
När ledarskapet krackelerar
Att utöva ledarskap är ofta svårt. Inte sällan krackelerar eller kullkastas försök att leva upp till tjusiga ledarskapsideal. Boken skildrar ledarskapsförsök i praktiken och den bökiga verkligheten snarare än ledarskapsfantasier i en perfekt värld. Även om chefer gärna vill se sig som ledare med ambitioner att åstadkomma allt möjligt strategiskt och visionärt så är medarbetare inte alltid lyhörd

A GaN HEMT power amplifier with variable gate bias for envelope and phase signals
This paper describes the design, simulation and measurement of a GaN power amplifier suitable for envelope and phase signal combination. The low-frequency envelope signal is used to vary the gate (bias) voltage of the device, resulting in a pulse width modulated drain voltage, while modulation of supply voltage or current is avoided. The test circuit is implemented using a discrete GaN HEMT power

Utvärderingsmodell för flexibla arbetstider inom Malmö kommun
Malmö stad antog 1997 en ny personalpolicy, P2006, vilken är indelad i sju profilområden. Ett av dessa profilområden har som målsättning att utveckla flexibla arbetstidsmodeller som ska tillgodose verksamhetens, kundens och den anställdes önskemål, samt skapa förutsättningar för alternativa karriärvägar för personalen. I samband med en utvärdering av de flexibla arbetstidsmodellerna uppdrogs åt S

Climate Change, Adaptation and Formal Education: The Role of Schooling for Increasing Societies' Adaptive Capacities
With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries that are most at risk. There is an urgent need to better understand the factors that determine people’s capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity

Strong Participator Channels in the Non-Radiative Resonant Decay of B 1s Excitation in B2O3
We observe and analyze a considerable enhancement of photoelectron intensity of the valence band features in solid B2O3 upon tuning the photon energy across the B 1s → π*2pz resonance. This enhancement is an evidence of the strong 2p electron correlations in pre-edge photoionization dynamics in boron oxide. Such strength of the correlation is unusual for a solid, whose valence band is composed of
