A Discrete-Time Extended Kalman Filter Approach Tailored for Multibody Models: State-Input Estimation.

Model-based force estimation is an emerging methodology in the mechatronic community given the possibility to exploit physically inspired high-fidelity models in tandem with ready-to-use cheap sensors. In this work, an inverse input load identification methodology is presented combining high-fidelity multibody models with a Kalman filter-based estimator and providing the means for an accurate and computationally efficient state-input estimation strategy. A particular challenge addressed in this work is the handling of the redundant state-description encountered in common multibody model descriptions.

Intermittent venovenous haemodiafiltration in critically ill patients with acute renal failure.

Various renal replacement therapies have been used for the treatment of acute renal failure in critically ill patients in the last decade. Due to the slower rate of solute and fluid removal, the continuous renal replacement therapies are generally better tolerated than conventional therapy. There is no consensus whether different treatment strategies effect the outcome of critically ill patients and no clear definition of adequacy of renal support in the severely ill patient.

Autogenous saphenous vein AV fistulae for haemodialysis: eight years experience with 30 patients.

Since 1973, 41 autogenous saphenous vein (ASV) fistulae in the arm or the leg have been constructed in 30 chronic haemodialysis patients. The mean patency rate for the arm fistulae was 36.8 months and 21.
