  2. 6. Experimental Bladder Reconstruction

    Author : Hans Frederiksen; Urologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urology; smooth muscle; detrusor; matrix; nerves; subtotal cystectomy; bladder regeneration; enterocystoplasty; nephrology; Urologi; nefrologi;

    Abstract : Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. READ MORE

  4. 7. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness

    Author : Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-time domain; Frequency-domain identification; Signal processing; Frequency-domain; Automatic control; Reglerteknik;

    Abstract : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. READ MORE

  5. 8. The Use of Landweber Algorithm in Image Reconstruction

    Author : Touraj Nikazad; Tommy Elfving; George Baravdish; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; convex feasibility; projection methods; simultaneous algorithms; iterative methods; stopping rules; semi-convergence; Numerical analysis; Numerisk analys;

    Abstract : 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 modelled using the Radon transform. After expanding the solution into a finite series of basis functions a large, sparse and ill-conditioned linear system arises. READ MORE

  6. 9. Predictors of Outcome after Anterior Cruciate Ligament Reconstruction

    Author : Eric Hamrin Senorski; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; ACL; reconstruction; physcial therapy; concomitant injury; knee; predictors; outcome;

    Abstract : An anterior cruciate ligament (ACL) injury is one of the most common injuries to the knee joint. It is also one of the most researched areas within sports medicine, orthopedics and physical therapy. READ MORE

  7. 10. Time-domain Reconstruction Methods for Ultrasonic Array Imaging : A Statistical Approach

    Author : Fredrik Lingvall; Tadeusz Stepinski; Karl-Jörg Langenberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Ultrasonic array imaging; synthetic aperture imaging; maximum a posteriori estimation; linear minimum mean squared error estimation; SAFT; Bayesian image reconstruction; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : This thesis is concerned with reconstruction techniques for ultrasonic array imaging based on a statistical approach. The reconstruction problem is posed as the estimation of an image consisting of scattering strengths. READ MORE
