This dissertation aims at understanding differences in rates of returns on financial assets, both in the cross-section and over time. It contains four chapters. The first paper is "Non-separable preferences and risk aversion: Results from the UK". Due to poor empirical support of the Consumption Capital Asset Pricing Model it has been suggested that the model should be specified as being non-separ

Policy makers are showing increasing interest in factors that make places attractive for prospective new residents. This paper focuses on residential preferences for interregional migration and aims to explore what place attributes people would value highly if they considered migrating. Special attention is given to differences in preferences between population subgroups in terms of demographic, s

End-tidal PCO2 (PET CO2 ) has been used to estimate arterial pressure CO2 (Pa CO2 ). However, the influence of blood temperature on the Pa CO2 has not been taken into account. Moreover, there is no equation validated to predict Pa CO2 during exercise in severe acute hypoxia. To develop a new equation to predict temperature-corrected Pa CO2 values during exercise in normoxia and severe acute hypoxi

The 60 GHz band is very promising for high data rate (>1 Gb/s) wireless systems operating at short ranges. However, due to the short wavelengths in this frequency band, the shadowing effects cuased by human bodies and furniture are severe and need to be modeled properly. In this paper, we present an experimental, measurement-based characterization of the reflection and shadowing effects in the 60

Popular Abstract in Swedish I och med de smarta mobiltelefonernas framväxt överförs allt mer data i de mobila nätverken. Detta ställer allt högre krav på mobilsystemen och de mobila enheterna. Ett effektivt utnyttjande av de tillgängliga resurserna är nödvändigt. Det tillgängliga frekvensspektrat är begränsat och måste utnyttjas så väl som möjligt. Detta görs bland annat genom att öka mängden dataIn this thesis different aspects of baseband implementation of mobile communication systems is treated. The content is focused on symbol detection and channel estimation in MIMO and OFDM. The thesis deals with the complete chain from algorithm to silicon implementation within these areas. The main contribution of this thesis is described in the included papers. The first paper handles symbol dete

The forward scattering sum rule relates the extinction cross section integrated over all wavelengths with the polarizability dyadics. It is useful for deriving bounds on the interaction between scatterers and electromagnetic fields, antenna bandwidth and directivity and energy transmission through sub-wavelength apertures. The sum rule is valid for linearly polarized plane waves impinging on linea

I tidigare artiklar (Sverige – EEG och konkurrensen - SvJT 1974: s. 18-33) aktualiserades relationen mellan konkurrensrätt och immaterialrätt. Den regionala konsumtionsprincipen utvecklas under de kommande åren genom en omfattande rättspraxis. Däremot har det varit oklarare vad som gäller för produkter från omvärlden. Sätter de gemensamma reglerna en minimistandard för EU, som innebär att medlemss

Software release planning can be described as a process consisting of the following three phases: (i) strategic release planning, i.e. the assignment of features to subsequent releases, (ii) operational release planning, i.e. the allocation of resources to tasks within each individual release, and (iii) dynamic re-planning, i.e. the revision of plans to handle unexpected changes imposed on product

As mobile map services are becoming increasingly popular, it is important to use a cartography that can provide good readability in reduced formats. The amount of information presented in a map is important for understandability and is thus an essential aspect of map usability. In addition, the limited memory capacities of many mobile devices make it necessary that only the most important informat

Industrialized production of building components, or entire houses, reduces activities at the construction site to the assembly of parts and has the potential to increase productivity and reduce the design effort invested in every project. However, in order to realize all of the potential efficiency gains that use of predefined components could deliver effective, interoperable information manageme
