In this article we evaluate the work out of artificial neural networks as tools for helping and support in the medical diagnosis. In particular we compare the usability of one supervised and two unsupervised neural network architectures for medical diagnoses of lower urinary tract dysfunctions. The purpose is to develop a system that aid urologists in obtaining diagnoses, which will yield improved

Popular Abstract in Swedish Arbetet med denna avhandling har handlat om en abnormal fosfolipid (fettämne) som bildas i kroppens celler endast när alkohol är närvarande, lipiden kallas fosfatidyletanol (PEth). För att lättare kunna förstå resultaten av våra undersökningar börjar jag med en kort bakgrund. Alla kroppens celler är omgärdade av ett membran som skiljer dem från varandra och omgivningen.Phosphatidylethanol (PEth) is an abnormal phospholipid formed exclusively by the action of phospholipase D (PLD) in the presence of ethanol. The degradation of PEth is slow and due to its accumulation in some cells the possibility to use PEth as marker of ethanol intake has been proposed. It has also been suggested that PEth mediates some of the damaging effects of ethanol on cells. This study was

In high performance concrete (HPC) with low water-cement ratio, cement reaction will cause substantial drying expressed in terms of relative humidity (RH) of the pore water. This phenomenon is called self-desiccation. The RH-values as low as 85% have been measured in dense concretes that have been stored for more than 18 months in water. This means that there is almost no freezable water in the co

We consider a problem of calculating covering capabilities for convolutional codes. An upper bound on covering radius for convolutional code is obtained by random coding arguments. The estimates on covering radius for some codes with small constraint length are presented.

The aim of the article is to add a sociological perspective on the subject of religion. This will be based on a review of the development of the subject, based on a critical analysis of the 2011 curriculum and curriculum for the subject of religion, both for primary school curricula for teacher education at the university as well as a textbook on religion.

I artikeln presenteras en översiktlig teori om avtalsfrihet och rättvisa samt vilken betydelse som denna teori kan ha för lagstiftningens utformning.

Realtidsövning för lärande i sammanhang är en övning i ett verklighetstroget scenario där studenterna tar beslut och agerar i realtid, samt systematiskt reflekterar över dessa beslut och handlingar. Det är detta systematiska och lärarledda växelspel mellan självständigt agerande och reflektion som är realtidsövningens viktigaste särdrag. Denna övningsform kan vara ett värdefullt verktyg i akademis

Short obituary over Swedish cinematographer Sven Nykvist 1922 - 2006.

New methods and products must be developed to reduce our dependency on fossil fuels, to reduce global warming. In this work, methods of extracting and isolating hemi¬celluloses from agricultural and forestry waste streams have been studied. Hemi¬celluloses are biodegradable polymers that can replace fossil-fuel-based products for use in various applications, such as barrier films and hydrogels. Ar

Popular Abstract in Swedish Beräkningar från Cancerfonden visar på att ungefär var tredje person i Sverige kommer att få en cancerdiagnos under sin livstid. Cancerceller är celler som har utvecklat speciella förmågor som gör att de har börjat dela sig ohämmat. Denna ohämmade celldelning leder till bildandet av en tumör och när tumören har nått ett visst stadie i sin utveckling så börjar den spridaAs a cancer grows it will, at a certain stage of disease progression, start spreading in the body. For several types of cancer this spreading will first occur through the lymphatic system and the first place where metastatic cell will be encountered is the first lymph node that drains the area where the tumor is located. This lymph node is defined as the sentinel lymph node (SLN). By analyzing the
