This research was undertaken in an aerospace company, which manufactures aero engines and also offers contracts, under which it remains responsible for the maintenance of engines. These contracts allow the company to collect far more data about the in-service performance of their engines than was previously available. This paper aims at understanding what parts of this in-service information are a

Thermostimulated and photostimulated luminescence of ZnWO4, ZnWO4:Fe and ZnWO4:MO Crystals irradiated at low temperatures by X-rays or UV photons was studied in the temperature range 4.2-300 K in order to clarify the creation and recombination processes of the elementary colour centres. The connection of the luminescence phenomena with the self-trapped holes has been revealed. (C) 2003 Published b

House dust mites are animals of a size less than 0.5 mm that can live in beds, carpets and furniture feeding on skin scales. They are a common source of allergy in, e.g., Scandinavia, where their major habitat is in beds. Previous studies show that in drier environments the house dust mite occurrence is lower, and persons with dust mite allergy have fewer symptoms during the winter when the indoor

Lattice Boltzmann method (LBM) is an alternative to conventional CFD to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the hydrogen production by splitting water by incident sunlight over water covered Si-nanorods. The purpose of this study is, by a 3D microscale model, to investigate the transport and the formation of the hydrogen bubbles by el

Abstract in UndeterminedThe paper describes a magnetizing machine for producing permanent magnets of desired magnetization pattern by use of feedback control. This will in theory mean that an ideal magnetization pattern can be realized, what could be described as a perfect magnet. The machine is to be used for applications requiring high accuracy magnets in terms of the shape of the magnetized are

Summary – 200 words In education today, there is a paradigm shift with critical challenges for Universities to enhance innovation in teaching and learning. Knowledge and learning are critical issues for most companies and private and civil service organizations with today’s rapid changes in socio-economy and technology. The needs for competence development vary along a broad scale from short info

This paper looks at the how a new kind of South Scandinavian radical left emerged around 1990. It argues that its repertoire of contention neither can be understood as simply a product of struggles in local contexts or as diffusion of an already existing repertoire through trans-local mobilisations. The contingent history of the counter-claims to the far right Charles XII march in Lund throughout

The advent of foundation models signals a new era in artificial intelligence. The Segment Anything Model (SAM) is the first foundation model for image segmentation. In this study, we evaluate SAM's ability to segment features from eye images recorded in virtual reality setups. The increasing requirement for annotated eye-image datasets presents a significant opportunity for SAM to redefine the lan

Laser-induced fluorescence is a technique for optical tissue characterisation. It has a real-time capability and as the excitation light and the fluorescence emission are transmitted through optical fibres the technique is compatible to various kinds of endoscopes for hollow organ investigation. The tissue fluorescence itself with the emission from the endogenous chromophores or enhanced with exog

There are all sorts of consumer electronics in a home environment. Using ”apps” to interact with each device is neither feasible nor practical in an ubicomp future. Prototyping and evaluating interaction concepts for this future is a challenge. This paper proposes four concepts for device discovery and device interaction implemented in a virtual environment. The interaction concepts were compared

The anisotropic local electric fluctuations within a nanoscopic sphere of a polar fluid surrounded by vacuum are analysed using dielectric theory and molecular simulation. The electric fluctuations are characterized through the mean-square multipole moments (Q(l)(2)), which are related to the dielectric constant of the fluid. The results show that the fluctuations are suppressed close to the fluid

The transcription factor Wilms' tumor gene 1 (WT1) is highly expressed in the majority of leukemias, suggesting a role in leukemogenesis. Acquired WT1 mutations are reported as an independent predictor of poor clinical outcome, and mutations resulting in deletion of the entire DNA-binding zinc-finger domain (WT1delZ), is the most common type. The aim of this study was to study cellular effects of

This paper describes a case of collaboration between academia and business firms in supporting innovation processes based on the CILO method, named after the CILO project (communication in learning organizations). The CILO method is an example of firm-supportive research approach. We describe the outcomes related to enhancing enterprise performance from applying the CILO-method in relation to one

The goal of the paper is to present a decomposed approach to optimization of inter-domain routing in IP networks. A problem of maximizing the total amount of traffic carried in an inter-domain network is formulated as a linear programme. Using Lagrangean relaxation the problem is decomposed with respect to individual domains. A resolution method based on subgradient optimization combined with reco
