For some time, directional antennas have been considered to solve connectivity and interference issues in wireless networks. Several scenarios have been presented and often the conclusions drawn are positive, showing increase in capacity. However, to date there has been no effort to assess a holistic picture of the benefit/cost tradeoff and previous work mainly concerns either link scheduling or a

Det försvunna fascinerar, ofta mer än det som finns i behåll. Bilden måste återskapas inom oss. Till ledning finns minnesbilder, rester av det försvunna, eller indirekta avtryck som foton, teckningar och beskrivningar. Att återskapa kräver efterforskningar och stimulerar fantasin. Särskilt lockande kan det vara att rekonstruera försvunna byggnader, konkreta avtryck av människor som levat tidigare.

In this study we compare two types of Large Eddy Simulation (LES) turbulent combustion models with experimental data for a low swirl stabilized turbulent lean premixed flame. Such flames are a great challenge to numerical simulations since they are unsteady and sensitive to boundary conditions, and details of the experimental set-up. The two classes of LES turbulent combustion models considered ar

The work presented in this paper deals with the use of green gluing (also known as wet gluing) as a mean to overcome the difficulties in making use of side boards for structural applications. By manufacturing laminated beams from unseasoned side boards several advantages are obtained. Beams were manufactured from side boards of approximately 25 mm thickness. The board width was 120 mm. The boards

To study the process of domestic market integration in Lao People’s Democratic Republic (hereafter Lao PDR), this chapter explores the spatial variation in beer prices and its relationship with transport costs and various local market characteristics. More specifically, we study how the price of a 640 ml bottle of Beer Lao varies across the country. In a well- integrated market, we expect the law

Popular Abstract in Swedish Arcanobacterium haemolyticum (A. haemolyticum) beskrevs för första gången under namnet Corynebacterim haemolyticum av MacLean och medarbetare 1946. Bakterien odlades fram från svalget hos patienter med halsont och från sår. Patienterna bestod av amerikanska soldater och infödda öbor i Stilla havet. Från olika delar av världen har senare beskrivits halsont och utslag hosIn an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial and e

The aim of this book is to explore how contemporary notions of reconciliation as a process of building, rebuilding and transforming relationships may be applied not only to “race” but also to gender relations in post-apartheid and post-TRC South Africa. After highlighting links between the past, the present and the future with regard to such relations in wider South African society, critical quest
