In the present work the feasibility of using various optical/laser based techniques for characterization of the afterburner of a full-size aircraft engine have been investigated. The tests have been performed on-site at Volvo Aero Corporation and were mainly directed towards surface thermometry using thermographic phosphors and fuel visualization. All applications were studied for different engine
This article discusses the role of archaeology in our society as well as the epistemological outlook within archaeology. In order to illustrate the relevance of archaeology in our own age three topics are formulated - landscape archaeology, the long-term perspectives of archaeology and the norms and values of our particular system. It is underlines that archaeologists are interpreters of fragments
I kapitlet diskuteras samhällsfenomenet med att idag en ny form av tjänster, ledarskapsutveckling, kompetensutveckling och terapeutiska tjänster, erbjuds av privata företag eller enskilda entreprenörer utan att några krav på officiellt dokumenterad kompetens ställs.
The Functional Mockup Interface (FMI) is a tool independent standard for the exchange of dynamic models and for co simulation. The first version, FMI 1.0, was published in 2010. Already more than 30 tools support FMI 1.0. In this paper an overview about the recently published version 2.0 of FMI is given that combines the formerly separated interfaces for Model Exchange and Co-Simulation in one sta
A new concept of treating abdominal aortic aneurysms was studied during a three-year period. Instead of open repair, graft insertion was accomplished endovascularly from the groins. The graft was attached by expandable stents to the non-dilated infrarenal aorta, i.e. the aneurysmal neck, and to the iliac artery/ies. Pre- and postoperative work-up included CT-scanning, angiography and ultrasonograp
In this paper we describe a systematic study on long-term evolution of residential broadband Internet traffic covering 5 calendar years from June 2007 to May 2011. The traffic evolution is characterized both in the term of the total traffic volume, as well as the traffic volumes and shares for different application categories (file sharing, video streaming etc.), with the focus on comparing the tr
Internationellt sett har de fackliga organisationerna i Sverige på flera sätt mycket goda förutsättningar att verka för hållbara arbetsplatser. Hit hör den höga organisationsgraden, den välutbyggda fackliga arbetsplatsorganisationen, en relativ frånvaro av facklig rivalitet samt den långa traditionen av samarbete mellan arbetsmarknadens parter. Sedan 1990-talet förefaller facken på många arbetspla
Abstract in UndeterminedContrary to the notion that altering our ordinary state of consciousness necessarily produces delusional beliefs and is generally deleterious, various findings in psychology and other disciplines suggest that 1) the ordinary state of consciousness does not provide an accurate mapping of reality and 2) alterations of consciousness can have various positive functions. Among t
We propose a novel approach to estimation, where each individual observation in a random sample is used to derive an estimator of an unknown parameter using the maximum likelihood principle. These individual estimators are then combined as a weighted average to produce the final estimator. The weights are chosen to be proportional to the likelihood function evaluated at the estimators based on eac
