Hogesnelheidslagers vormen een hoofdbestanddeel in een toenemend aantal toepassingen. Gasgesmeerde lagers bieden voor dit toepassingsdomein vers cheidene voordelen ten opzichte van andere, meer klassieke lagertechnolo gieën: quasi-sleetvrije werking, een schone en olievrije oplossing, bepe rkte wrijvingsverliezen, een ruim temperatuurbereik enz. De voornaamste beperking van gasgesmeerde lagers betreft echter het dynamische stabilit eitsprobleem ...

Validation of ecological models is not a straightforward task and much controversy exists in the published literature on the exact definition. A lot of approaches have been suggested, without one being clearly superior. In this paper, we use the earlier published dynamic 'RCGro' tree water flow and storage model as an illustrative example to address some model validation issues. We show that the model fails validation when confronted with a data ...

Liberalising the European electricity industry did not naturally produce its intended results. Network constraints, few dominant sellers in a relatively small market, complex market designs, price-inelastic consumers, reductions in generation capacity, unavailability of perfect information provided in real-time, and portfolio economics and technical characteristics induced the observed strategic gaming behaviour of generators.In order to ...

BACKGROUND: In clinical practice, the right heart filling status is assessed using the respirophasic variation of the inferior vena cava (IVC) assessed by transthoracic echocardiography (TTE) showing moderate correlations with the catheter-based reference standard. PURPOSE: To develop and validate a similar approach using MRI. STUDY TYPE: Prospective. POPULATION: 37 male elite cyclists (mean age 26 ± 4 years). FIELD STRENGTH/SEQUENCE: Real-time ...

Skin and coat scores have been used to assess changes in skin and coat quality in dogs. The aim of this study was to evaluate a skin and coat protocol in dogs of different coat types. Skin and coat of long-haired, short-haired and wire-haired dogs were scored for alopecia, glossiness, greasiness, softness, scaliness and overall skin and coat quality by ten observers. Intraobserver and interobserver agreement was assessed using kappa values. ...

Het succesvol en snel ontwerpen van moderne draadloze communicatiesystemen hangt meer en meer af van robuuste en nauwkeurige niet-lineaire gedragsmodellen. Ultiem worden deze modellen direct geëxtraheerd uit grootsignaalmetigen met realistische, gemoduleerde signalen. Dit werk is gericht op het praktisch realiseren van zulke meetmogelijkheden met de bestaande grootsignaal-netwerkanalyser-opstelling, en op het gebruik van de gemeten data voor het ...

Studies to identify the genetic defects associated with X-linked mental retardation (XLMR) in males have revealed tens of genes important for normal brain development and cognitive functioning in men. Despite extensive efforts in breakpoint cloning of chromosomal rearrangements and mutation screening of candidate genes on the X chromosome, still many XLMR families and sporadic cases remain unsolved. It is now clear that submicroscopic copy ...

The marine environment is subjected to increasing anthropogenic pressure. Although there is a willingness of the different activities to minimize their impacts, there is a strong need for the assessment of the ecological value of the seabed, comprising both the abiotic substrate and the living organisms related to it (together called a ‘habitat’). Therefore, ‘habitat mapping’ is crucial, not only for the assessment of the ecological value at a ...
