In this paper two figures of merit of UE antenna performance are compared, the mean effective gain (MEG) and the total radiated power gain (TRPG). The ratio between these magnitudes has been evaluated first theoretically and later from measurements of four different handsets in the GSM, AMPS bands. In the evaluation different power angular distribution models were assumed. It is also shown that in
Biofuel production in the world has grown exponentially, stimulated by public policies, in countries of the North as well as of the South, and has been seen as one of the main drivers behind the recent food price hike. Thus conflicts over land need to be factored in when biofuels are assessed. Nowhere in the world is biofuel production seen to be more successful – economically, ecologically – than
Chapter 1 develops a framework to investigate the impact of the financial crisis starting in 2007 and employs an extended GARCH model to test for spillover and contagion effects originating from the financial sector. We find that the financial crisis affects financially distressed firms more heavily than non-distressed firms. Financial constraints do not play an equally crucial role during the cri
Institutionen för Designvetenskaper på lth presenterar här sitt första forskningsprogram inom området "Äldre och Design". Flera av institutionens forskningsavdelningar har en mångårig, i vissa fall tioårig tradition på området, och nu förs insatserna sa
In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. The advantage of this stroboscopic method compared to conventional time-averaging techniques, is the time-resolution it provides as well as being non-invasiv
