IT Track or People Track?

Risberg, Patrik January 2006 (has links)
This thesis deals with knowledge management at companies in the Falun-Borlänge region. The purpose is to create better understanding of which path companies have chosen and why, respectively. A qualitative survey seeks to discover if companies have chosen IT track or people track. This is a practical and useful model for an evaluative study. In the same context, a number of important models for evaluating knowledge management are presented. The result shows that the companies provide a multitude of training within several frameworks. Education is mostly provided in a traditional manner but there are many examples of interactive state-of-the-art training. Furthermore, most of the companies primarily focus upon people and processes, but some focus at technical facilities as well. In some cases are the technical frameworks used for support of core processes.

Die Änderung der Fentanylplasmakonzentration während orthotoper Lebertransplantation

Michalski, Caroline 04 July 2013 (has links) (PDF)
Die orthotope Lebertransplantation (OLT) ist ein etabliertes Standardtherapieverfahren von Endzuständen verschiedenster Lebererkrankungen. Bei Patienten mit Lebererkrankungen kommt es zu einer deutlichen Reduktion der hepatischen Metabolisierung und Elimination von verschiedensten Medikamenten. Fentanyl ist das Opioid der Wahl im Rahmen der Anästhesie bei Patienten mit Lebererkrankungen. Die Pharmakokinetik von Fentanyl ist besonders in der anhepatischen Phase durch einen Ausfall der hepatischen Elimination gekennzeichnet, sodass es zu hohen Plasmakonzentrationen von Fentanyl kommen kann. Besonders bei der Fentanylinfusion bis zur Reperfusion kann dies zu einer verzögerten Extubation führen, welche im Rahmen des Fast-Track-Verfahrens vermieden werden sollte. Hauptanliegen unserer Studie ist der Vergleich zweier Infusionsregimes für das Opioid Fentanyl, nämlich der Beendigung der Fentanylapplikation mit Beginn der anhepatischen Phase (Studiengruppe) und zum Zeitpunkt der Reperfusion (Kontrollgruppe). Dazu wurden von 22 Patienten (Studiengruppe: n=10; Kontrollgruppe: n=12) intraoperativ zu neun definierten Messzeitpunkten (MZP) die Verläufe der arteriellen Fentanylplasmakonzentration, sowie von Parametern des Säure-Basen-Haushaltes und der hämodynamische Messwerte erfasst. Die Bestimmung der Fentanylkonzentration erfolgte mit Hilfe der Flüssigchromatographie mit Massenspektrometrie (SSQ 7000, Finnigan), der Säure-Basen-Haushalt mittels Blutgasanalyse (ABL 700, Radiometer Medical A/S, Kopenhagen). Hinsichtlich der Daten für MELD-Score, Diagnose und Gesamtoperationsdauer unterschieden sich die beiden Gruppen nicht signifikant voneinander. Im Verlauf der anhepatischen Phase lag die Fentanylkonzentration im Plasma in der Kontrollgruppe signifikant höher als in der Studiengruppe. Die gefundenen höheren Fentanylspiegel in der Kontrollgruppe sind Ausdruck einer nicht vorhandenen hepatischen Fentanylclearance in der anhepatischen Phase. Basierend auf unseren Daten wollen wir zu einer Überprüfung des Infusionskonzeptes von Fentanyl bei OLT anregen. Während einer OLT sollte im Hinblick auf das Fast-Track-Konzept über eine Beendigung der Fentanylzufuhr zum Beginn der anhepatischen Phase nachgedacht werden.

Multi-Function LIDAR Sensors for Non-Contact Speed and Track Geometry Measurement in Rail Vehicles

Wrobel, Shannon Alicia 03 June 2013 (has links)
A Doppler LIght Detection And Ranging (LIDAR or lidar) system is studied for the application of measuring train ground speed in a non-contacting manner, as an alternative to the current train speed measurement devices such as wheel-mounted tachometers or encoders. The ability to accurately measure train speed and distance is a critical part of monitoring track geometry conditions. Wheel-mounted tachometer speed measurements often fluctuate due to wheel vibrations, change in wheel diameter, or wheel slip affecting the measurement accuracy.  Frequent calibrations are needed to account for changes in wheel diameter due to wear.  Additionally, the high levels of vibrations at the wheel can cause occasional mechanical failure of the encoder.   This thesis examines LIDAR as a non-contact train speed measurement device as a direct retrofit for wheel-mounted encoders. LIDAR uses Doppler technology to accurately measure train speed. The LIDAR system consists of two laser sensors and can be installed on either the car body or the truck on the underside of the train. The sensors measure the true ground speed of each rail, from which the track curvature can then be assessed based on the difference between the right and left rail speeds. The LIDAR train speed, distance, and curvature results are then evaluated against encoder readings and other conventional train measurement devices. Various tests were performed, including field-testing onboard a track geometry railcar operated by Norfolk Southern for evaluating the efficacy, accuracy, and durability of the LIDAR system; and laboratory tests on a 40-foot rail panel for assessing the ability to obtain measurements at super low speeds. The test results indicate that when compared with other conventional means used by the railroad industry, LIDAR is capable of accurately measuring train speed and distance from speeds as slow as 0.3 mph and up to 100 mph.  Additionally, the curvature  measurements proved to be as accurate as Inertial Measurement Units (IMUs) that are commonly used in track geometry measurement railcars. / Master of Science
