We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0
Theever-increasing test data volume for core-based system-on-chip(SOC) integrated circuits is resulting in high test times andexcessive tester memory requirements. To reduce both test time andtest data volume, we propose a technique for test-architectureoptimization and test scheduling that is based on core-levelexpansion of compressed test patterns. For each wrapped embeddedcore and its decompres
A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre
A recent study of ours suggested that the very presence of a Teachable Agent (TA) from a mathematics learning game might affect students’ test performance when the TA reappeared in the margin of a regular, digital math test. We hypothesized that this effect, which seemed to particularly target low-achievers, was due to the students’ mindset changing from that of “taking a test” to that of “teachin
Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f
Controlling an induction machine has been a difficult task since its invention, especially at low speed operation and during highly dynamic regimes, where the required torque/speed changes constantly. This paper aims to present the validation and implementation of a deadbeat direct torque and flux control scheme (DB-DTFC) for induction machines on a multilevel platform consisting on an FPGA, a rea
This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
We investigate a model for buffer management of multi-class traffic into a finite shared buffer. A hierarchy of increasingly stronger linear programming relaxations for this model is proposed. The number of hierarchies equals the number of job classes. Each relaxation in the hierarchy is constructed by projecting the original achievable performance region into a polytope with fewer variables and f
Popular Abstract in English N/AAquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere. In the boreal region, loadings of AlloOC are particularly high due to leaching from huge or
Against the deeply ingrained belief that technology is instrumental and neutral, this thesis argues that our relation to technology is inextricably bound up with fantasies. But what is the nature of these fantasies and where do we find them? Are they strictly reserved to the domain of Science Fiction, or can we also find them in more mundane contexts, like the business organization? These are som
