The high time resolution of ultra-wideband (UWB) signals results in a large number of multipath components (MPCs) arriving at the receiver, which presents a source of diversity. In addition to this multipath diversity, there is also repetition diversity inherent in impulse radio (IR) UWB systems, since a number of pulses are transmitted for each information symbol. In order to make optimal use of
In this work, we report an original experimental approach for measuring the two-dimensional distribution of the droplets Sauter Mean Diameter (SMD) using the SLIPI-LIF/Mie technique. A hollow-cone spray is formed by continuously injecting water mixed with a non-toxic fluorescing dye at 20 bars injection pressure. The spray is illuminated using a continuous wave laser. The illumination wavelength (
Popular Abstract in Swedish Idén om att företag försöker koordinera sina handlingar för att försöka förhindra rivalitet mellan dem har en lång historia inom nationalekonomin och den har undersökts relativt grundligt. Trots detta är många frågor fortfarande obesvarade och den här avhandlingen ämnar försöka besvara några av dessa. Avhandlingen kan delas in i två relaterade delar. För det första, ävChapter 2 investigates an infinitely repeated Bertrand duopoly where firms with different discount factors bargain over which collusive price and market share to implement. The bargaining is modelled as a strategic game and the main results of the paper is that it shows existence of a unique subgame perfect equilibrium and that the least patient firm's equilibrium market share is not monotone in i
Socware is the name for a new design cluster in Sweden, which intends to unify university, research institutes, and industry towards a common goal, namely System-on-Chip. One of the parts of the program is related to Research & Education where new Master’s and PhD student course curriculums are developed at Swedish Universities. This paper presents the initiative at Lund University. The curric
It has been shown previously that methylamine is incorporated into the alpha-chain of human C4, resulting in a loss of haemolytic function and the appearance of a free thiol group in the molecule. In the present study it was demonstrated that a fragment resembling C4d is liberated from C4 by trypsin. The fragment--Try-C4d--contains both the methylamine binding site and the free thiol group. When s
The climatic conditions at the concrete containment wall surfaces of two nuclear reactor containments were examined and quantified as a basis for predicting the drying process. Two types of nuclear reactor containments were studied, for a BWR reactor and a PWR reactor in Sweden. They both have a thick concrete wall with a steel lining inside, but the BWR containment walls are enclosed in a buildin
Wireless local area networks (WLAN) are rapidly becoming a core part of network access. Supporting user mobility, more specifically session continuation in changing network access points, is becoming an integral part of wireless network services. This is because of the popularity of emerging real-time streaming applications that can be commonly used when the user is mobile, such as voice-over-IP a
