In addition we use the same DGCN to detect detours within a route. In our application, a classification of routes and their underlying graph structure is performed using Graph Learning. Our model leads to a fast prediction and avoids solving the vehicle routing problem (VRP) through expensive computations. Moreover, we describe how to predict travel time for all routes using the same DGCN Model. This method makes it possible not to use a more computationally intensive approximation algorithm when determining long travel times with many intermediate stops, but to use our network for an early estimate of the quality of a route. Long travel times, in our case result from the use of a call-bus system, which must distribute many passengers among several vehicles and can take them to places without a regular stop. For a case study, the rural town of Roding in Bavaria is used. Our training data for this area results from an approximation algorithm that we implemented to optimize routes, and to generate an archive of routes of varying quality simultaneously.}, language = {en} } @article{MatuschDepboyluPalmetal., author = {Matusch, Andreas and Depboylu, Candan and Palm, Christoph and Wu, Bei and H{\"o}glinger, G{\"u}nter U. and Sch{\"a}fer, Martin K.-H. and Becker, Johanna Sabine}, title = {Cerebral bio-imaging of Cu, Fe, Zn and Mn in the MPTP mouse model of Parkinsons disease using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)}, series = {Journal of the American Society for Mass Spectrometry}, volume = {21}, journal = {Journal of the American Society for Mass Spectrometry}, number = {1}, doi = {10.1016/j.jasms.2009.09.022}, pages = {161 -- 171}, abstract = {Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been established as a powerful technique for the determination of metal and nonmetal distributions within biological systems with high sensitivity. An imaging LA-ICP-MS technique for Fe, Cu, Zn, and Mn was developed to produce large series of quantitative element maps in native brain sections of mice subchronically intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP) as a model of Parkinson's disease. Images were calibrated using matrix-matched laboratory standards. A software solution allowing a precise delineation of anatomical structures was implemented. Coronal brain sections were analyzed crossing the striatum and the substantia nigra, respectively. Animals sacrificed 2 h, 7 d, or 28 d after the last MPTP injection and controls were investigated. We observed significant decreases of Cu concentrations in the periventricular zone and the fascia dentata at 2 h and 7d and a recovery or overcompensation at 28 d, most pronounced in the rostral periventricular zone (+40\%). In the cortex Cu decreased slightly to -10\%. Fe increased in the interpeduncular nucleus (+40\%) but not in the substantia nigra. This pattern is in line with a differential regulation of periventricular and parenchymal Cu, and with the histochemical localization of Fe, and congruent to regions of preferential MPTP binding described in the rodent brain. The LA-ICP-MS technique yielded valid and statistically robust results in the present study on 39 slices from 19 animals. Our findings underline the value of routine micro-local analytical techniques in the life sciences and affirm a role of Cu availability in Parkinson's disease.}, subject = {ICP-Massenspektrometrie}, language = {en} } @techreport{SteffensRechenauerNeuleitneretal., author = {Steffens, Oliver and Rechenauer, Christian and Neuleitner, Nikolaus and Seidl, Erwin and Kemper, Peter and Nigl, Bernhard and Rozankovic, Andreas and Laumer, Johann and Stierstorfer, Johannes and Gerstner, Julian and Zacher, Markus and Zimmermann, Patrick and Primbs, Sebastian and Sch{\"a}fer, Sebastian and Schmidbauer, Florian and Tretter, Simon}, title = {Effizienzhaus Plus Deggendorf-Natternberg: Modellvorhaben im Netzwerk „Effizienzhaus Plus" der Forschungsinitiative Zukunft Bau gef{\"o}rdert vom Bundesinstitut f{\"u}r Bau-, Stadt- und Raumforschung (BBSR), Endbericht 2017}, publisher = {OTH Regensburg}, address = {Regensburg}, doi = {10.35096/othr/pub-5840}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-58404}, pages = {63}, abstract = {Dokumentation, Vorbereitungen und Ergebnisse der zweij{\"a}hrigen Messperiode vom 01.11.2014 bis 31.10.2016 Ausgehend von Konzeption und Planungsdaten f{\"u}r das Effizienzhaus Plus der Firma Karl Bachl GmbH \& Co.

Die OTH Regensburg wurde mit der wissenschaftlichen Begleitforschung dieses Modellprojekts im Rahmen des Zukunft-Bau-Netzwerks Effizienzhaus Plus1 beauftragt. Das Geb{\"a}ude wird vorwiegend solarthermisch beheizt, erg{\"a}nzt durch eine elektrische Nachheizung. Neben Solarkollektoren befinden sich auch PV-Module auf dem Dach, deren Ertr{\"a}ge den Jahresstrombedarf bilan- ziell decken. Durch Einsatz eines Batteriespeichers kann der Anteil des selbst genutzten PV-Stroms erh{\"o}ht werden. Die Gesamtbilanz des ersten Jahres zeigt, dass das Geb{\"a}ude prim{\"a}r- und endenergetisch die Anforderungen an den Effizienzhaus Plus Standard erf{\"u}llt. Wir stellen die Energiefl{\"u}sse, Gewinne und Verbr{\"a}uche, sowie die Wirkungsgrade, den solaren und elektrischen Deckungsgrad und den Autarkiegrad des Geb{\"a}udes im Detail vor und diskutieren den Einfluss des elektrischen Batteriespeichers sowie der thermischen Verluste aus dem Pufferspeicher. Verbesserungspotentiale werden in der Beseitigung von haustechnischen Fehlfunktionen und in einer st{\"a}rkeren D{\"a}mmung des Pufferspeichers gesehen. Dieser ist zudem f{\"u}r den beabsichtigten Zweck nach den Erkenntnissen aus den empirischen Messungen zu groß dimensioniert, wodurch sich f{\"u}r k{\"u}nftige Projekte ein Einsparungspotential ergibt.}, language = {de} }
