Total laparoscopic hysterectomy of very enlarged uterus (3030 g): case report and review of the literature

Fibromatosis is the most frequent benign uterine pathology of fertile women, rarely causing anomalous enlargement of the uterus. Traditionally the surgical treatment has been abdominal hysterectomy. However, development of minimally invasive techniques has led to major safeness of the laparoscopic route. We report a case of total laparoscopic hysterectomy performed on a uterus weighting more th...

Analysis of Skin Reflectance using Beckmann-Kirchhoff Scattering and a Cyberware 3030 Scanner

Reflectance data provides both important information for surface analysis tasks in computer vision as well as enabling more realistic renderings by capturing the appearance of an object under varying illumination conditions and orientation. Human skin in particular has proven consistently difficult to model because of its complex structure and layered nature. We perform an analysis of skin radi...

Performance Analysis of Robust Averaging Level Control, Report no. LiTH-ISY-R-3030

Frequent inlet flow changes, especially in the same direction, typically cause problems for averaging level controllers. To obtain optimal flow filtering while being robust towards future inlet flow upsets closed loop robust MPC was used. Its performance and robustness is analyzed and compared to the optimal averaging level controller. The knowledge gained from the robust MPC exercise is also u...

Robot Motion Vision Part II: Implementation

The idea of Fixation introduced a direct method for general recovery of shape and motion from images without using either feature correspondence or optical flow [1,2]. There are some parameters which have important effects on the performance of fixation method. However, the theory of fixation does not say anything about the autonomous and correct choice of those parameters. This paper presents ...
