  1. 6. Öster om Arlanda : En etnologisk studie av berättelser och föremål i en hemslöjdsinventering

    Författare :Åsa Ljungström; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethnology; ethnology; folkloristics; interview; personal experience narratives; narrated time; world view; values; dignity; care; artifact; handicraft; cammoditization; home museum; women s studies; modernization; Etnologi; Ethnology; Etnologi; Etnologi; Ethnology;

    Sammanfattning : This dissertation lies in the crossroads between the study of artifacts and the studyof verbalizations. Its purpose is to investigate how artifacts, retrieved for ahandicraft inventory, inspired their owners to narrate and interpret values, lifecontexts and moral problems connected with the social and historicaltransformation of the twentieth century.

  3. 7. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

    Författare :MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). LÄS MER

  4. 8. On Enterprise Systems Artifacts: Changes in Information Systems Development and Evaluation

    Författare :Jonas Hedman; Institutet för Ekonomisk forskning; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information systems development; evaluation; artifact evaluation; artifacts; systemteori; Informatik; Informatics; systems theory; Enterprise Systems; ERP Systems;

    Sammanfattning : Enterprise Systems are one of the most important developments in corporate information systems during the last decade. These integrated information systems are characterized by a number of features which include a very broad scope and functionality, as well as being generic, master data, and business-process orientated.

  5. 9. Contributions to Signal Processing for MRI

    Författare :Marcus Björk; Peter Stoica; Andreas Jakobsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; efficient estimation algorithms; non-convex optimization; multicomponent T2 relaxometry; artifact reduction; T2 mapping; denoising; phase estimation; RF design; MR thermometry; in-vivo brain; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is an important diagnostic tool for imaging soft tissue without the use of ionizing radiation. Moreover, through advanced signal processing, MRI can provide more than just anatomical information, such as estimates of tissue-specific physical properties. LÄS MER

  7. 10. A New Audiometric Bone Vibrator, Radioear B81, and the Bone Conduction Implant with Emphasis on Magnetic Resonance Imaging

    Författare :Karl-Johan Fredén Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image artifact; magnetically induced torque; balanced electromagnetic separation transducer; magnetic resonance imaging.; bone vibrator; bone conduction; retention magnet; demagnetization;

    Sammanfattning : Hearing by air conduction (AC) and bone conduction (BC) are attributed to be the natural ways of stimulating the cochlea. With AC hearing, the cochlea is stimulated by air pressure variations via the ear canal, whereas with BC hearing, sound vibrations are transmitted thru the skull bone to the cochlea. LÄS MER
