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

Welinders Swedish history of archaeology: A review of Stig Welinder’s book “Min svenska arkeologihistoria” (My Swedish history of archaeology) (2003).

OBJECTIVE. Severe (PiZZ) alpha(1)-antitrypsin (AAT) deficiency is a risk factor for liver disease, i.e. juvenile cirrhosis in infancy, and cirrhosis and hepatoma in adulthood. Little is known about the risk of liver disease in individuals with moderate (PiSZ) AAT deficiency. To investigate the natural course of AAT deficiency, a cohort of PiZZ and PiSZ individuals identified by the Swedish Nationa

There is a functional relationship between the heparan sulfate proteoglycan glypican-1 and the amyloid precursor protein of Alzheimer disease. In wild-type mouse embryonic fibroblasts, expression and processing of the amyloid precursor protein is required for endosome-to-nucleus translocation of anhydromannose-containing heparan sulfate released from S-nitrosylated glypican-1 by ascorbate-induced,

In 1867 Alexander Melville Bell conceived the high-low front-back tongue position model for vowels, including the concept of central vowels. This model was rapidly accepted by the phonetics community, but it has never been validated. This article reports an examination of 38 sets of X-ray tracings of vowels from 15 different languages, published in the past half century. This corroborates the char

Objective. To investigate the inter- and intra-observer reliability of both qualitative and quantitative parameters used in the assessment of nail-fold capillaroscopy images.Methods. Fifty mosaic nail-fold images of healthy controls (n = 10), patients with primary RP (n = 10) and SSc (n = 30) were assessed in random order by two blinded observers on two occasions at centres in Sweden, UK and The N

Popular Abstract in Swedish Fjärrvärme är ett centraliserat uppvärmningssystem där varmt vatten distribueras i ett rörnätverk och används främst till byggnadsuppvärmning och för att värma varmvatten. Fjärrvärme finns i alla länder på norra halvklotet men har störst marknadsandel i Norden och Baltikum. I Sverige används fjärrvärme för att värma c:a 60% av all byggnadsyta. Två stora fördelar med fjäRenewable energy sources dominated the world energy supply until the beginning of the 20th century, when fossil energy became the dominant energy source worldwide. Today, fossil fuels contribute to over 80% of world energy supply. But there are two major reasons why fossil energy use has to stop. First, fossil energy is limited and will not last forever. Second, emissions of carbon dioxide change

The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. The calorimeter is made in a hodoscopic fashion from position sensitive crystal rods measuring 333.0 × 26.7
