The aggregation of typical operation periods has become a popular method to reduce effort. These operation periods are modelled independently and cannot interact in most cases. Consequently, seasonal storage is not reproducible. This inability can lead to a significant error, especially for energy systems with a high share of fluctuating renewable energy. The previous paper, "Time series aggregation for energy system design: Modeling seasonal storage", has developed a seasonal storage model to address this issue. Simultaneously, the paper "Optimal design of multi-energy systems with seasonal storage" has developed a different approach. This paper aims to review these models and extend the first model. The extension is a mathematical reformulation to decrease the number of variables and constraints. Furthermore, it aims to reduce the calculation time while achieving the same results.}, language = {en} } @inproceedings{ValeroVogelSchmidtetal.2018, author = {Valero, Daniel and Vogel, Jochen and Schmidt, Daniel and Bung, Daniel B.}, title = {Three-dimensional flow structure inside the cavity of a non-aerated stepped chute}, series = {7th IAHR International Symposium on Hydraulic Structures, Aachen, Germany, 15-18 May}, booktitle = {7th IAHR International Symposium on Hydraulic Structures, Aachen, Germany, 15-18 May}, isbn = {978-0-692-13277-7}, doi = {10.15142/T3GH17}, pages = {12 Seiten}, year = {2018}, language = {en} } @inproceedings{LopesBungLeandroetal.2015, author = {Lopes, Pedro and Bung, Daniel B. and Leandro, Jorge and Carvalho, Rita F.}, title = {The effect of cross-waves in physical stepped spillway models}, series = {E-proceedings of the 36th IAHR World Congress ; 28 June - 3 July, 2015, The Hague, the Netherlands}, booktitle = {E-proceedings of the 36th IAHR World Congress ; 28 June - 3 July, 2015, The Hague, the Netherlands}, organization = {International Association for Hydro-Environment Engineering and Research}, pages = {1 -- 9}, year = {2015}, language = {en} } @inproceedings{Mueller2007, author = {M{\"u}ller, Karsten}, title = {Strategien zur Zustandserfassung von Kanalisationen}, series = {Integration in der Abwasserentsorgung : Tagungsband Dresden, 04.10.2007 / Dresdner Kolloquium zur Siedlungswasserwirtschaft / Hrsg.: Peter Krebs.

(S. 136-137) Eine nachhaltige Sicherung der Funktionalit{\"a}t und der {\"o}kologischen Vertr{\"a}glichkeit eines mittleren bis großen Kanalnetzes erfordert eine umfassende und detaillierte Modellierung in Raum und Zeit. Um den in den Richtlinien geforderten statistischen Anforderungen gerecht zu werden und die j{\"a}hrlichen H{\"a}ufigkeiten, Mengen und Zeitr{\"a}ume der Belastungen erwartungstreu absch{\"a}tzen zu k{\"o}nnen, ist es zielf{\"u}hrend und notwendig, lange Zeitr{\"a}ume und die Gesamtheit der Einzugsgebiete m{\"o}glichst detailliert zu betrachten. Die hydraulische Funktionalit{\"a}t und Sicherheit soll meistens mit Hilfe zeitsymmetrischer (hydrodynamischer) Verfahren nur durch Betrachtung von Modellregen, allenfalls Regenserien, sichergestellt werden. F{\"u}r die Absch{\"a}tzung der j{\"a}hrlich zu erwartenden Emissionen in unsere nat{\"u}rlichen Gew{\"a}sser mit ihren Mengen, Frequenzen und Dauern werden normalerweise Langzeitsimulationen nat{\"u}rlicher Regenreihen {\"u}ber m{\"o}glichst große Zeitr{\"a}ume mit zeitasymmetrischen (hydrologischen) Verfahren durchgef{\"u}hrt. Die betrachteten Kanalnetze werden zumeist vereinfacht (Grobnetze), um die Rechenzeiten ertr{\"a}glicher zu gestalten. W{\"u}nschenswert w{\"a}re jedoch eine allen Anforderungen gerecht werdende wirklichkeitsnahe Modellierung des gesamten Kanalnetzes in all seinen Details, Vermaschungen und Wechselwirkungen (Feinnetz) und dessen zeitsymmetrische und damit verl{\"a}ssliche Simulation mit langj{\"a}hrigen Regenreihen. Bereits vor 15 Jahren wurde im Hause Tandler begonnen, die Berechnungssoftware durch Parallelisierung auf symmetrische Multiprozessortechnologien auszurichten. In neuerer Zeit h{\"a}lt diese Technik durch die Mehrkernprozessoren in normalen Notebooks und PCs Einzug in die Ingenieurb{\"u}ros und Abwasserbetriebe und sorgt schon f{\"u}r wesentliche Einsparungen an Rechenzeit. Doch erst durch die Kombination der Parallelisierung mit dem Prinzip des verteilten Rechnens (d.h. die Einbeziehung mehrerer PCs eines Netzwerkes in die Berechnung) erh{\"a}lt man die Chance ausreichend Rechenkapazit{\"a}t zur Verf{\"u}gung zu stellen, um nicht nur eine einzelne Langzeitsimulation eines Feinnetzes durchzuf{\"u}hren, sondern sogar mehrere Sanierungsalternativen zu {\"u}berpr{\"u}fen.

The purpose of this paper is to analyse the opportunities and obstacles to implementing BIM for prefabrication. Among all other advantages of BIM, prefabrication is chosen for this paper because it plays a vital role in creating an impact on the time and cost factors of a construction project. The project stakeholders and participants can explicitly observe the positive impact of prefabrication, which enables the breakthrough of the scepticism factor among the small-scale construction companies. The analysis consists of the development of a process workflow for implementing prefabrication in building construction followed by a practical approach, which was executed with two case studies. It was planned in such a way that, the first case study gives a first-hand experience for the workers at the site on the BIM model so that they can make much use of the created BIM model, which is a better representation compared to the traditional 2D plan. The main aim of the first case study is to create a belief in the implementation of BIM Models, which was succeeded by the execution of offshore prefabrication in the second case study. Based on the case studies, the time analysis was made and it is inferred that the implementation of BIM for prefabrication can reduce construction time, ensures minimal wastes, better accuracy, less problem-solving at the construction site. It was observed that this process requires more planning time, better communication between different disciplines, which was the major obstacle for successful implementation.

Besides other advantages, this allows a continuous remote monitoring of the data from the numerous sensors at an arbitrary sampling rate.Based on the recorded data, we will also present first results from numerical simulations, taking into account all relevant heat transport processes.The aim is to improve the understanding of these processes and their influence on the thermal behavior of shallow geothermal systems in the unsaturated zone.

Aachener Softwaretag in der Wasserwirtschaft <2, 2009, Aachen> Zusammenfassung [der Autoren] F{\"u}r das st{\"a}dtisch gepr{\"a}gte Einzugsgebiet des Broicher Baches sind ein vereinfachter und ein detaillierter Nachweis nach BWK-M3 durchgef{\"u}hrt worden. Dabei zeigt sich, dass die Methodik des vereinfachten Nachweises nicht geeignet ist, um eine realit{\"a}tsnahe Abbildung der einleitungsgepr{\"a}gten Abfl{\"u}sse des Gew{\"a}ssers zu erhalten. Dies ist insbesondere auf die Vernachl{\"a}ssigung von Wellentranslation und -retention im Gerinne zur{\"u}ckzuf{\"u}hren. Die dadurch entstehende Fehleinsch{\"a}tzung der Abflussverh{\"a}ltnisse versperrt den Blick auf eine situationsgerechte Maßnahmenplanung. Der mit Hilfe eines NA-Modells gef{\"u}hrte detaillierte Nachweis ist zwar in der Erstellung aufw{\"a}ndiger, zeichnet aber ein reales Bild der Abflusserh{\"o}hung durch Einleitungen. Mit Hilfe des Modells k{\"o}nnen die wesentlichen Einfl{\"u}sse schnell lokalisiert und zielf{\"u}hrende Maßnahmenvarianten identifiziert werden. In dem hier vorgestellten Beispiel des Broicher Baches k{\"o}nnen die urspr{\"u}nglich identifizierten acht Maßnahmen auf eine reduziert werden. Das Gesamtvolumen der erforderlichen R{\"u}ckhaltungen wird um die H{\"a}lfte verringert. Der Vergleich beider Nachweismethoden legt nach Ansicht der Autoren nahe, den vereinfachten Nachweis h{\"o}chstens f{\"u}r eine erste Einsch{\"a}tzung des Maßnahmenbedarfs anzuwenden. Die Maßnahmenidentifikation und -dimensionierung sollte grunds{\"a}tzlich mit der detaillierten Nachweismethode durchgef{\"u}hrt werden, die auf einem entsprechenden NA-Modell basiert. Dies gilt insbesondere f{\"u}r Gew{\"a}sserstrecken, deren Abfluss durch mehrere, hintereinander liegende Einleitungsstellen gepr{\"a}gt ist.}, subject = {Fließgew{\"a}sser}, language = {de} } @inproceedings{SchulzeBuxlohGross2021, author = {Schulze-Buxloh, Lina and Groß, Rolf Fritz}, title = {Miniature urban farming plant: a complex educational "Toy" for engineering students}, series = {The Future of Education 11th Edition 2021}, booktitle = {The Future of Education 11th Edition 2021}, pages = {4 Seiten}, year = {2021}, abstract = {Urban farming is an innovative and sustainable way of food production and is becoming more and more important in smart city and quarter concepts. It also enables the production of certain foods in places where they usually dare not produced, such as production of fish or shrimps in large cities far away from the coast. Unfortunately, it is not always possible to show students such concepts and systems in real life as part of courses: visits of such industry plants are sometimes not possible because of distance or are permitted by the operator for hygienic reasons. In order to give the students the opportunity of getting into contact with such an urban farming system and its complex operation, an industrial urban farming plant was set up on a significantly smaller scale. Therefore, all needed technical components like water aeriation, biological and mechanical filtration or water circulation have been replaced either by aquarium components or by self-designed parts also using a 3D-printer. Students from different courses like mechanical engineering, smart building engineering, biology, electrical engineering, automation technology and civil engineering were involved in this project. This "miniature industrial plant" was also able to start operation and has now been running for two years successfully. Due to Corona pandemic, home office and remote online lectures, the automation of this miniature plant should be brought to a higher level in future for providing a good control over the system and water quality remotely. The aim of giving the student a chance to get to know the operation of an urban farming plant was very well achieved and the students had lots of fun in "playing" and learning with it in a realistic way.}, language = {en} } @inproceedings{Engels2007, author = {Engels, Ralf}, title = {MIKE URBAN FLOOD: Modellkopplung von Kanalnetzmodell und 2D Oberfl{\"a}chenmodell}, year = {2007}, abstract = {Dipl.-Ing. Ralf Engels - DHI Wasser und Umwelt GmbH, Syke. 24 S. (S. 70-93) Beitrag zum 1. Aachener Softwaretag in der Wasserwirtschaft <1,2007, Aachen> Einleitung [des Autors] Die hydrodynamische Kanalnetzmodellierung ist ein Standardwerkzeug f{\"u}r die Bemessung von Kanalnetzen. Neben der Berechnung der hydrologischen und hydraulischen Gegebenheiten in einem st{\"a}dtischen Einzugsgebiet geh{\"o}ren auch weiterf{\"u}hrende Technologien mittlerweile zum Standard. So k{\"o}nnen alle steuerbaren Elemente eines Kanalnetzes dynamisch so optimiert werden, dass die Leistungsf{\"a}higkeit des Kanalnetzes zus{\"a}tzlich gesteigert werden kann. Automatische Werkzeuge zur dynamischen hydraulischen Schmutzfrachtberechnung erm{\"o}glichen die Erweiterung der Steuerung - insbesondere von Entlastungsanlagen - im Hinblick auf die entlasteten Schmutzfrachten und geben dar{\"u}ber hinaus detaillierte Informationen f{\"u}r den Betrieb der Kl{\"a}ranlage. Weiterf{\"u}hrende biologische Prozessmodellierungen erg{\"a}nzen dieses Themenfeld. GIS Werkzeuge k{\"o}nnen bei der r{\"a}umlich differenzierten Modellierung von Kanalnetzen wertvolle Dienste leisten. Die detaillierte Betrachtung einzelner Haltungsfl{\"a}chen in ihrem r{\"a}umlichen Zusammenhang ist damit ebenso m{\"o}glich wie eine komplette Verwaltung aller f{\"u}r die Kanalnetzmodellierung notwendigen Daten in einem {\"u}bersichtlichen grafischen Men{\"u}. Die Grenzen der Kanalnetzmodellierung lagen in fr{\"u}heren Zeiten an dessen Rand. Detaillierte Informationen {\"u}ber die Wege des Wassers auf der Gel{\"a}ndeoberfl{\"a}che, an der Schnittstelle zu Vorflutern und in der Interaktion mit Grundwasser waren bisher nicht modelltechnisch bewertbar. Eine dynamische Kopplung verschiedener Modelle zur Darstellung aller relevanten hydraulischen Prozesse erm{\"o}glicht eine integrative Betrachtung aller m{\"o}glichen Wege, die das Wasser in der Stadt nehmen kann (Mark \& Djordjevic, 2006).
