1. 11. Cerebrospinal fluid infusion methods : development and validation on patients with idiopathic normal pressure hydrocephalus

   Författare :Nina Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Infusion test; idiopathic normal pressure hydrocephalus; outflow conductance; outflow resistance; intracranial pressure; cerebrospinal fluid dynamics; medical informatics; medicinsk informatik;

   Sammanfattning : Cerebrospinal fluid (CSF) infusion tests can be used to estimate the dynamic properties of the CSF system. Idiopathic normal pressure hydrocephalus (INPH) is a syndrome signified by a disturbance to the CSF system, where the cause is unknown and the diagnosis is difficult to determine. LÄS MER

3. 12. Algebraic Reconstruction Methods

   Författare :Touraj Nikazad; Tommy Elfving; Constantin Popa; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iterative methods; image reconstruction; ART; Cimmino; Kaczmarz; Landweber; sequential iteration; simultaneous iteration; block iteration; semi-convergence; relaxation parameters; stopping rules; discrepancy principle; Numerical analysis; Numerisk analys;

   Sammanfattning : Ill-posed sets of linear equations typically arise when discretizing certain types of integral transforms. A well known example is image reconstruction, which can be modeled using the Radon transform. After expanding the solution into a finite series of basis functions a large, sparse and ill-conditioned linear system occurs. LÄS MER

4. 13. Hybrid Built-In Self-Test and Test Generation Techniques for Digital Systems

   Författare :Gert Jervan; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; system-on-chip; test generation; BIST; hybrid BIST; high-level test; Datavetenskap; Computer science; Datavetenskap;

   Sammanfattning : The technological development is enabling the production of increasingly complex electronic systems. All such systems must be verified and tested to guarantee their correct behavior. As the complexity grows, testing has become one of the most significant factors that contribute to the total development cost. LÄS MER

5. 14. Assessment of central auditory functions : methods and applications

   Författare :Mathias Hällgren; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Central auditory processing is complex and can not be completely evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests, cognitive tests that tax functions important for speech processing and electrophysiological tests.

7. 15. Experimental test setups and simulations in skiing mechanics

   Författare :Mikael Swarén; Anders Eriksson; Thomas Stöggl; KTH; []
   Nyckelord :sports equipment; test methods; sports mechanics; alpine skiing; cross-country skiing; poles; helmets; glide; performance;

   Sammanfattning : Product testing and development are essential parts in sports and for the athletes in their quest to reach the podium. Manufacturers of sports equipment often use basic test methods which do not test the equipment in a sports specific way. LÄS MER
