   Sammanfattning : The diagnostic activity for prostate cancer has increased substantially in Sweden, primarily due to increased use of prostate-specific antigen (PSA) testing in asymptomatic men, and this has led to a large increase in diagnoses. There have also been changes in the diagnostic workup, guidelines, treatment strategies, and more effective treatments have been introduced in different phases of the disease. LÄS MER

5. 4. Road profile statistics relevant for vehicle fatigue

   Författare :Klas Bogsjö; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; Matematik; Mathematics; model evaluation; vehicle fatigue; stochastic processes; road roughness; Road profiles; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

   Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER
