TY - THES A1 - Meesters, Elena T1 - Gestaltung eines häuslichen Telemonitoringsystems zur Prognose kardialer Dekompensation N2 - Herzinsuffizienz ist eine der häufigsten Herzerkrankungen in Deutschland. Sie ist fortschreitend und nicht heilbar. Der Krankheitsverlauf ist geprägt von plötzlichen, z.T. lebensbedrohlichen Verschlechterungen und Krankenhauseinweisungen, nach denen die Leistung des Herzen vermindert bleibt. Diese Dekompensationen lassen sich bisher im heimischen Umfeld nicht durch Messwerte vorhersehen. Dieses Gerät bestimmt die Flüssigkeitsansammlungen in der Lunge, die ein mittelfristiges Symptom einer Dekompensation sind. Außerdem misst es über einen Hautsensor die im Schweiß enthaltene Menge eines Proteins, das bei Überdehnung des Herzmuskels vermehrt im Blutplasma zu finden ist. So können Dekompensationen bis zu zwei Wochen vor einem akuten Ereignis detektiert und behandelt werden. Außerdem gibt es tagesformabhängige Tipps für die Alltagsgestaltung mit der Erkrankung.

Mechanically, thepelvic organ support system are of two types: (I) supporting system of the levator ani (LA) muscle,and (II) the suspension system of the endopelvic fascia condensation [1], [2]. Significantdenervation injury to the pelvic musculature, depolimerization of the collagen fibrils of the softvaginal hammock, cervical ring and ligaments during pregnancy and vaginal delivery weakens thenormal functions of the pelvic floor. Pelvic organ prolapse, incontinence, sexual dysfunction aresome of the dysfunctions which increases progressively with age and menopause due toweakened support system according to the Integral theory [3]. An improved 3D finite elementmodel of the female pelvic floor as shown in Fig. 1 is constructed that: (I) considers the realisticsupport of the organs to the pelvic side walls, (II) employs the improvement of our previous FEmodel [4], [5] along with the patient based geometries, (III) incorporates the realistic anatomy andboundary conditions of the endopelvic (pubocervical and rectovaginal) fascia, and (IV) considersvarying stiffness of the endopelvic fascia in the craniocaudal direction [3]. Several computationsare carried out on the presented computational model with healthy and damaged supportingtissues, and comparisons are made to understand the physiopathology of the female PF disorders.

The open-volumetric receiver uses ambient air as heat transfer fluid and the hybridization is realized with a gas turbine. The Rankine cycle is heated by solar-heated air and/or by the gas turbine's flue gases. The plant can be operated in solar-only, hybrid parallel or combined cycle-only mode as well as in any intermediate load levels where the solar portion can vary between 0 to 100%. The simulated plant is based on the configuration of a solar-hybrid power tower project, which is in planning for a site in Northern Algeria. The meteorological data for Barstow-Daggett was taken from the software meteonorm. The solar power tower simulation tool has been developed in the simulation environment MATLAB/Simulink and is validated.
