1. Generalised linear models with clustered data
Sammanfattning : In situations where a large data set is partitioned into many relativelysmall clusters, and where the members within a cluster have some common unmeasured characteristics, the number of parameters requiring estimation tends to increase with sample size if a fixed effects model is applied. This fact causes the assumptions underlying asymptotic results to be violated. LÄS MER

3. Multivariate Exploration and Processing of Sensor Data-applications with multidimensional sensor systems
Sammanfattning : A sensor is a device that transforms a physical, chemical, or biological stimulus into a readable signal. The integral part that sensors make in modern technology is considerable and many are those trying to take the development of sensor technology further. LÄS MER
4. Optimization of Snow Removal in Cities
Sammanfattning : Removing snow in a city is an unavoidable task in Nordic countries like Sweden. A number of streets in an area need to be cleared of snow by a limited number of vehicles and the tours for the vehicles must be planned in order to minimize the time and/or cost. LÄS MER
5. Anticoagulants in kidney disease
Sammanfattning : Background: Patients with chronic kidney disease (CKD) and atrial fibrillation (AF) are at high risk of ischemic stroke. Evidence is lacking if patients with advanced CKD or on dialysis benefit from oral anticoagulants (OAC) as stroke prophylaxis. LÄS MER
