Lately there has been increasing research on the Mixed Capacitated General Routing Problem (MCGRP) – a generalization of the Capacitated Vehicle Routing Problem and the Capacitated Arc Routing Problem. Although it is an important aspect of real-life VRPs, route balancing has drawn surprisingly...
Problemstilling: Rapporten oppsummerer effekten av ti psykososiale behandlingstiltak for personer med dobbeldiagnose (samtidig alvorlig psykisk lidelse og ruslidelse). De til behandlingstiltakene er integrert behandling, case management, aktivt oppsøkende behandling, kognitiv atferdsterapi...
Objective - The purposes of this study were to determine the association between physical activity (PA) behavior and global cognitive function 3 months after stroke and to explore the role of physical capacity as a mediating factor. Methods - Participants with stroke were successively recruited at...
Background and objective:Ultrasound based blood velocity estimation is a continuously developing frontier, where the vast number of possible acquisition setups and velocity estimators makes it challenging to assess which combination is better suited for a given imaging application. FLUST, the Flow...
Thin film samples of Mg80Ti20 (Mg–Ti) and Mg, both with and without H, were investigated in a series of X-ray photoelectron spectroscopy (XPS) measurements. The samples were covered with a thin protective layer of Pd, which was removed by Ar+ sputtering prior to data acquisition. This sputtering was...
During ageing, 6xxx aluminium alloys will develop a microstructure characterised by needle-shaped Mg/Si-rich precipitates in the bulk, precipitate-free zones along the grain boundaries and larger Mg/Si-rich precipitates on the grain boundary. Depending on, among other things, the size of the...
Ceria (CeO2) exhibits high reversible oxygen storage capacity at intermediate temperatures (500–800 °C) related to an extraordinary and not fully understood reduction of its surfaces. We have investigated pristine and alcohol-dispersed commercially available ceria nanoparticles by in-situ scanning...
Defects in high performance multi-crystalline silicon wafers can be detrimental to the lifetime of the solar cell. It is, therefore, important to study and understand the underlying structure and chemical elements present at these defective areas in order to suppress them. The underlying cause of...
Alkanolamines used for CO2-capture in natural gas (NG) may be released to the marine environment from coastal and offshore NG facilities. In this study biodegradation of alkanolamines in seawater was investigated. Screening of 20 alkanolamine candidates for ultimate biodegradability showed that...
Lately there has been an increase of research on the Mixed Capacitated General Routing Problem (MCGRP) – a generalization of the Capacitated Vehicle Routing Problem and the Capacitated Arc Routing Problem. Although it is an important aspect of real-life VRPs, route balancing has drawn surprisingly...
The interface between ZnO and Cu2O has been predicted to be a good candidate for use in thin film solar cells. However, the high predicted conversion efficiency has yet to be fully realized experimentally. To explore the underlying causes of this we investigate the interface between ZnO and Cu2O in...
Background: Hearing is essential for learning in school, and untreated hearing loss may hinder quality education and equal opportunities. Detection of children with hearing loss is the first step in improving the learning situation, but effective interventions must also be provided. Hearing aids can...
Vehicle routing problems (VRPs) have been well-studied since they were first introduced in combinatorial optimization theory some 55 years ago, both due to their scientific interest and a wide range of applications. For capacitated routing problems, the goal is to determine a set of routes for a...
