This paper is a pilot study where Swedish Facebook users are interviewed in virtual focus groups - one consisting of politically active participants and one consisting of not politically active participants - using Facebook itself as the platform. The interviews concerned the attitudes of the participants towards political campaigns and recruitment within Facebook. The preliminary results show tha

Multiuser detection is a powerful tool for combating cochannel interference in multiple-access communication systems. In this paper, we investigate the feasibility of achieving increased spectral efficiency in GSM-like TDMA networks by applying multiuser detection. Two special cases are considered: In the first scenario, two users are served simultaneously in the same cell. In the second one, two

The agile movement has received much attention in software engineering recently. Estab-lished methodologies try to surf on the wave and present their methodologies as being agile, among those Rational Unified Process (RUP). In order to evaluate the statements we evaluate the RUP against eXtreme Programming (XP) to find out to what extent they are similar and where they are different. We use a qual

Essän tar avstamp i en installation med uppstoppade hästar av konstnären Javier Balmaseda, visad på konstbiennalen i Venedig 2013. Diskussionen rör de etiska dimensionerna vid användning av djurkroppar i konsten, med referens även till Robert Rauschenbergs getinstallation "Monogram" på Moderna museet, samt till Steve Bakers forskning om djur i konsten, inklusive den nyutgivna boken Artist Animal.

This dissertation explores the migratory behaviour of nocturnally migrating passerines and common swifts (Apus apus). Birds passing Lund (southern Sweden) and Abisko (northernmost Scandinavia) where sampled using tracking radar. The aim has been to investigate potential diverging strategies between spring and autumn migration. We have found that both passerines and swifts compensate for wind drift

We calculate the phonon broadening in x-ray emission for Li, Na, Al, and K, treating the excitation and the subsequent emission as one quantum process. When the core-hole lifetime width is of the same order as the Debye energy, incomplete phonon relaxation gives a partial quenching of the Stokes shift and an additional width. This effect has previously not been seriously investigated; we find here

In this chapter, which is really a bigger appendix, the authors report the osteological analysis of the animal bones from Hovdala medieval castle. They discuss the material in terms of diet, slaughter strategies and animal husbandry. Also the importance of fish as well as hunting big game during this period are two themes discussed in the text.

In this paper, start-up of a plate reactor is considered. Dynamic optimization is used to obtain start-up trajectories, and a feedback control structure for on-line control. The problem is challenging, since the process model is large and highly non-linear. In addition, the plant is subject to uncertainty. Special attention is given to the problem of formulating an optimal control problem based on

In multiple-access communication systems co-channel interference can be mitigated by applying multiuser detection instead of treating the interference as additive noise [1]. In this paper we focus on downlink operation in a GSM-like TDMA network and investigate multiuser channel estimation and data symbol detection of two users that share the same physical channel in two adjacent cells. Such a sce

This study focusses on the urban infrastructure for water supply in Roman Pompeii. The water distribution network of lead pipes was constructed inside the city walls, at the time when the city was connected to an aqueduct. Life for the Pompeiians changed considerably when aqueduct water started running continuously in street fountains all around the city. The study is based on previous research an

I tre artiklar, som publicerade i samfundets tidskift 1976 analyseras de åtgärder, som med stöd av den nationella konkurrensbegränsningslagstiftningen riktas mot de marknadsdominerande företagen. Tre frågor lyftes fram: 1. I vilken utsträckning beivras traditionellt missbruk av en dominerande ställning; 2. Medger den interna lagstiftningen ingrepp mot företagssammanslagningar; 3. Ger de interna re
