Development of Deep Learning Models to Improve the Accuracy of Water Levels Time Series Prediction through Multivariate Hydrological Data
Authors: Park Kidoo , Jung Younghun , Seong Yeongjeong , Lee Sanghyup
Published: February 2022

Since predicting rapidly fluctuating water levels is very important in water resource engineering, Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) were used to evaluate water-level-prediction accuracy at Hangang Bridge Station in Han River, South Korea, where seasonal fluctuations were large and rapidly changing water levels were observed. The hydrological data input to each model were collected from the Water Resources Management Information System (WAMIS) at the Hangang Bridge Station, and the meteorological data were provided by the Seoul Observatory of the Meteorological Administration. For high-accuracy high-water-level prediction, the correlation between water level and collected hydrological and meteorological data was analyzed and input into the models to determine the priority of the data to be trained. Multivariate input data were created by combining daily flow rate (DFR), daily vapor pressure (DVP), daily dew-point temperature (DDPT), and 1-hour-max precipitation (1HP) data, which are highly correlated with the water level. It was possible to predict improved high water levels through the training of multivariate input data of LSTM and GRU. In the prediction of water-level data with rapid temporal fluctuations in the Hangang Bridge Station, the accuracy of GRU’s predicted water-level data was much better in most multivariate training than that of LSTM. When multivariate training data with a large correlation with the water level were used by the GRU, the prediction results with higher accuracy (R2=0.7480–0.8318; NSE=0.7524–0.7965; MRPE=0.0807–0.0895) were obtained than those of water-level prediction results by univariate training.

Published: February 2022

Water shortage and quality are major issues in many places, particularly arid and semi-arid regions such as Makkah Al-Mukarramah province, Saudi Arabia. The current work was conducted to examine the geochemical mechanisms influencing the chemistry of groundwater and assess groundwater resources through several water quality indices (WQIs), GIS methods, and the partial least squares regression model (PLSR). For that, 59 groundwater wells were tested for different physical and chemical parameters using conventional analytical procedures. The results showed that the average content of ions was as follows: Na+ > Ca2+ > Mg 2+ > K+ and Cl− > SO42− > HCO32− > NO3− > CO3−. Under the stress of evaporation and saltwater intrusion associated with the reverse ion exchange process, the predominant hydrochemical facies were Ca-HCO3, Na-Cl, mixed Ca-Mg-Cl-SO4, and Na-Ca-HCO3. The drinking water quality index (DWQI) has indicated that only 5% of the wells were categorized under good to excellent for drinking while the majority (95%) were poor to unsuitable for drinking, and required appropriate treatment. Furthermore, the irrigation water quality index (IWQI) has indicated that 45.5% of the wells were classified under high to severe restriction for agriculture, and can be utilized only for high salt tolerant plants. The majority (54.5%) were deemed moderate to no restriction for irrigation, with no toxicity concern for most plants. Agriculture indicators such as total dissolved solids (TDS), potential salinity (PS), sodium absorption ratio (SAR), and residual sodium carbonate (RSC) had mean values of 2572.30, 33.32, 4.84, and −21.14, respectively. However, the quality of the groundwater in the study area improves with increased rainfall and thus recharging the Quaternary aquifer. The PLSR models, which are based on physicochemical characteristics, have been shown to be the most efficient as alternative techniques for determining the six WQIs. For instance, the PLSR models of all IWQs had determination coefficients values of R2 ranging between 0.848 and 0.999 in the Cal., and between 0.848 and 0.999 in the Val. datasets, and had model accuracy varying from 0.824 to 0.999 in the Cal., and from 0.817 to 0.989 in the Val. datasets. In conclusion, the combination of physicochemical parameters, WQIs, and multivariate modeling with statistical analysis and GIS tools is a successful and adaptable methodology that provides a comprehensive picture of groundwater quality and governing mechanisms.

Published: February 2022

Intelligent connected vehicles (ICVs) technologies will bring significant changes to future transportation, and urban intersections will be an important scenario for the application of ICVs. There exists one significant challenge to address for the control of ICVs in unsignalized, multi-intersection road networks, that is, how to realize the comprehensive optimization of traffic efficiency and energy saving. To solve this problem, the distributed and hierarchical optimal control architecture is first established in this paper, consisting of a cloud decision layer and a vehicle control layer. For the cloud decision layer, the distributed model predictive control (DMPC) method is utilized for distributed optimization control of multi-intersection road network systems, to achieve optimization in terms of traffic efficiency. For the vehicle control layer, based on the reference speed optimized from the cloud decision layer, the DMPC method is further utilized for distributed optimal control of each vehicle platoon, to achieve optimization in terms of energy saving. Finally, the comparative simulation tests are carried out based on MATLAB and SUMO. The feasibility and effectiveness of the proposed method were verified, and the improvement of traffic efficiency and energy saving was achieved.

Рассмотрены вопросы оптимального уровня продуктивности коров черно-пестрой породы при сохранении продуктивного долголетия: раздой животных по 1 лактации, корреляция удоев за 1—8 лактации, влияние отцов и матерей на долголетие коров, потенциал молочной продуктивности матерей быков-производителей. Коровы с более высоким удоем за 1 лактацию имели лучшие удои за 3 и наивысшую лактации. С увеличением продуктивности за 1 лактацию свыше 7000 кг молока число лактаций снижается. Более выравненной продуктивностью за все лактации отличались коровы с удоем от 4000 кг до 7000 кг. Положительное влияние на раздой и пожизненную продуктивность дочерей имела продуктивность матерей. Наиболее высоким уровнем реализации потенциала продуктивности отличались особи с удоем матерей от 4000 кг до 6000 кг за лактацию. Положительная взаимосвязь удоя за лактацию установлена с родительским индексом коровы (0,251) и удоем за 305 дней наивысшей лактации матерей (0,251) и матерей отцов (0,254). Увеличение продуктивности матерей отцов за 305 дней наивысшей лактации способствует росту удоя за наивысшую лактацию дочерей. При этом дочери превосходят матерей по удою за наивысшую лактацию от 291 до 895 кг в среднем на 1 голову в зависимости от класса продуктивности матерей отцов.

Cows with a higher milk yield per lactation showed a better milk yield per 3 and the highest lactation. When the milk performance per lactation increased 7000 kg, the number of lactation cycles decreases. The most uniform milk performance throughout lactation cycles was shown by cows yielding 4000 to 7000 kg of milk. Milk performance of daughter cows depended on that of their mothers. The highest level of milk performance potential implementation was shown by specimens born by mothers yielding 4000 to 6000 kg per lactation. Positive interrelation of milk yield per lactation with the parent index of cows (0.251) and the milk yield for 305 days of the highest lactation of mother cows (0.251) and mothers of father cows (0.254). An increase in milk performance in mothers of father cows for 305 days of the highest lactation contributes to an increase in milk yield for the highest lactation of daughter cows. At that, daughter cows yield 291 to 895 kg more milk per cow than their mothers for the highest lactation, depending on the milk performance class of mothers of father cows.

Published: February 2022

Heavy metals recovery from Printed Circuit Boards industrial wastewater is crucial because of its cost effectiveness and environmental friendliness. In this study, a copper recovery route combining the sequential processes of acid leaching and LIX 984N extracting with an electrowinning technique from Printed Circuit Boards production’s sludge was performed. The used residual sludge was originated from Hanoi Urban Environment One Member Limited Company (URENCO). The extracted solution from the printed circuit boards waste sludge containing a high copper concentration of 19.2 g/L and a small amount of iron (0.575 ppm) was used as electrolyte for the subsequent electrolysis process. By using a simulation model for multi-step current electrolysis, the reasonable current densities for an electrolysis time interval of 30 minutes were determined, to optimize the specific consumption energy for the copper recovery. The mathematical simulation model was built to calculate the important parameters of this process.
Zielsystemunabhängiger Modellbasierter Entwurf auf der Basis von MATLAB/Simulink® mit einem vollständigen Model in the Loop-Test und automatischer Code-Generierung für einen Mischprozess
Authors: Büchau Bernd , Gröbe Gerald
Published: February 2022

Auf der Basis eines modellbasierten Entwurfs mit MATLAB/Simulink® wird der Entwurf für einen Mischprozess einer Mischstation vorgenommen. Durch den Einsatz der Toolbox PLC Coder™ von Mathworks® kann dieser Entwurf ohne jegliche Änderungen für aktuell 12 Automatisierungssysteme verschiedener Hersteller verwendet werden, so dass dies als ein zielsystemunabhängiger Entwurf angesehen werden kann. Der Vorteil besteht darin, dass nicht wie bisher ein klassischer Entwurf des Systems entsprechend IEC 61131 Teil 3 mit einer entsprechenden hersteller- bzw. systemspezifischen Entwicklungsumgebung durchgeführt wird, sondern ein hersteller- und systemunabhängiger Entwurf mit den zur Verfügung stehenden Werkzeugen von Simulink vorgenommen werden kann. Mit der verwendeten Toolbox PLC Coder™ für MATLAB/ Simulink® wird strukturierter Text nach IEC 61131 Teil 3 für das jeweilige Automatisierungssystem automatisch generiert. Im vorliegenden Fall wird als Automatisierungssystem eine SIMATIC ET 200SP Open Controller mit entsprechenden Erweiterungsmodulen (digitale und analoge Ein- und Ausgänge usw.) und das TIA Portal in der Version 15.1 der Fa. Siemens eingesetzt. Für den Mischprozess, eine Mischstation, werden Flüssigkeiten aus drei verschiedenen Behältern in verschiedenen vorgegebenen Mischverhältnissen und Mengen dosiert und in einen Mischbehälter ge-leitet. Hierfür wird der modellbasierte Entwurf primär mittels endlicher Zustandsautomaten mit einer unterlagerten Durchflussmengenregelung in insgesamt neun Subsystemen vorgenommen. Um eine möglichst hohe Genauigkeit des Mischproduktes zu erzielen, wird hierbei die Dosierung der verschie-denen Flüssigkeiten volumengesteuert vorgenommen. Für den vollständigen modellbasierten Entwurf der Automatisierung der Mischstation, dessen Visua-lisierung sowie der Modellierung des HMI mittels Apps des App Designers von MATLAB/ Simulink® wird ein vollständiger Model in the Loop (MIL)-Test in Realzeit zur Verifikation des Gesamtsystems durchgeführt, der hier den Schwerpunkt darstellt. Durch den auf einem deutlich höheren Abstraktionsniveau durchgeführten modellbasierten Entwurf und den MIL-Test werden die Implementierungs- und Inbetriebnahmephase minimal. Abschließend werden die wesentlichen Vorteile des modellbasierten Entwurfs behandelt und ein Aus-blick gegeben.

Published: February 2022

Digitale Zwillinge werden in der Betriebsphase einer Maschine oder Anlage für verschiedene Fragestellungen angewendet, bspw. für die Zustandserkennung. Voraussetzung dafür ist, dass der Digitale Zwilling über Modelle des Anlagenverhaltens verfügt, die verschiedene Zustände, einschließlich von Fehlerzustände, adäquat beschreiben. Ein wesentlicher Aspekt dabei ist die Identifikation der Modellparameter. Dieser Beitrag dient der Analyse und Anpassung ausgewählter Optimierungsmethoden (gradientenbasierter Verfahren und ein Partikelschwarmoptimierer) am Beispiel von Modellen für Kompressoren und Turbinenanlagen. Dazu wird mit einem analytischen Ansatz ein Modell einer realen Kompressoranlage erstellt. Um die Qualität der Optimierungsergebnisse vergleichen zu können, wird eine Fehlermetrik eingeführt. Das Verhalten der Optimierer wird unter den folgenden realistischen Fehlerszenarien ermittelt: Fehler in den Modellparametern, Rauschen, initialer Abstand vom Optimum, fehlerhaft Messstellen (ohne und mit Detektion). Zur numerischen Bewertung der Identifizierbarkeit werden zwei Kriterien eingeführt.

Published: February 2022

Die Wandelbarkeit von Anlagen im Kontext der Industrie 4.0 führt dazu, dass zukünftig Fertigungsmodule unterschiedlicher Hersteller interagieren müssen – es entsteht eine heterogene Modullandschaft. Das erfordert Lösungen für die automatisierungstechnische Einbindung und den flexiblen Austausch von weiteren, herstellerfremden und bislang unbekannten Modulen. Es werden Lösungskonzepte zur Umsetzung eines strukturierten und herstellerunabhängigen Engineering-Konzepts für Plug & Produce in einer heterogenen Landschaft von Fertigungsmodulen benötigt. Im Rahmen dieser Arbeit stellen die Autoren eine Architektur vor, wie dieses Ziel erreicht werden kann. Der Fokus liegt dabei auf der Steuerungsarchitektur, der Informationsmodellierung und der Virtuellen Inbetriebnahme als Grundlage für das gemischt real-virtuelle Engineering. Das vorgestellte Konzept basiert auf einer Anforderungsanalyse und ist prototypisch umgesetzt.

Published: February 2022

Mit der Anwendung der Norm ISO 50001 und der einhergehenden Einführung eines Energiemanagementsystems (kurz EnMS) kann eine sukzessive Erhöhung der Energieeffizienz erreicht werden. Zur Umsetzung von Energie-Monitoring- oder Standby-Management-Funktionalitäten müssen Energiedaten in der Feldebene bereitgestellt werden und auf Edge-Devices oder SPSen mittels eines Energiemanagement-Programms ggf. im Datenformat angepasst, skaliert und auf eine etablierte Kommunikationsschnittstelle (z.B. basierend auf OPC UA- oder MQTT) abgebildet werden. Die Erstellung dieser Energiemanagement-Programme geht mit einem hohen Engineering-Aufwand einher, denn die Feldgeräte aus der heterogenen Feldebene stellen die Energiedaten nicht in einer standardisierten Semantik bereit. Um diesem Engineering-Aufwand entgegenzuwirken, wird ein Konzept für ein universelles Energiedateninformationsmodell (kurz UEDIM) vorgestellt. Dieses Konzept sieht die Bereitstellung der Energiedaten an das EnMS in einer semantisch standardisierten Form vor. Zur weiteren Entwicklung des UEDIM wird im Beitrag näher untersucht, in welcher Form Energiedaten in der Feldebene bereitgestellt werden können und welche Anforderungen für das UEDIM aufzustellen sind.

Published: February 2022

In der Ingenieursausbildung ist die Arbeit an Anlagen und Maschinen ein wesentlicher Baustein, um die Anwendbarkeit, Möglichkeiten und Grenzen der in der Theorie vermittelten Methoden an praktischen Problemstellungen zu erproben und einschätzen zu lernen. Zu diesem Zweck werden an vielen Hochschulen und Universitäten unterschiedliche Versuchsanlagen eingesetzt. Die Errichtung und der Betrieb solcher Anlagen erfordern jedoch Platz und sind typischerweise mit hohem Einsatz personeller und finanzieller Ressourcen verbunden. Dieser Beitrag betrachtet den Einsatz virtueller Versuchsanlagen als eine mögliche Ergänzung der bestehenden Laborinfrastruktur. Virtuelle Anlage sind solche, die nicht physisch existieren, sondern deren dynamisches Verhalten simuliert und in einer 3D-Visualisierungen auf einem Monitor oder in einer VR-Brille dargestellt werden kann. Virtuelle Anlagen haben gegenüber realen Versuchsanlagen viele Vorteile in Bezug auf die Dauer und Kosten für deren Realisierung, sowie deren Erweiterung und Anpassung an neue Lehrinhalte und die Skalierung und Vervielfältigung für den Einsatz in Praktika. Auf der anderen Seite müssen Laboringenieure für die Entwicklung, Pflege und Instandhaltung virtueller Anlagen über andere Kompetenzen (insb. im Bereich der IT und Programmierung) verfügen, als bei realen Anlagen. Zudem wird für den Betrieb solcher Anlagen zusätzliche Soft- und Hardware benötigt. Am Beispiel eines virtuellen Aufzugs beschreibt dieser Beitrag im Einzelnen diese Vor- und Nachteile und gibt Hinweise für den Einsatz einer virtuellen Anlage in Praktika und Übungen.

Decentralized safety architecture for cyberphysical production systems
Authors: Faller Clemens , Schwoll Artur
Published: February 2022

In the context of the paper, a research work is shown to implement a networked decentralized safety architecture that replaces the central architecture. Thus, the safety system fits better into the rest of the automation structure. On the one hand, this is done by a clearer hardware structure, as there is now one safety controller per decentralized unit, which, analogous to the distributed automation system, communicates with the other stations via an Ethernet-based bus system, thus greatly reducing the wiring and commissioning effort. On the other hand, the decentralized processing allows a local shutdown of the safety-relevant components and an escalation of the emergency shutdown to other areas, depending on the emergency stop situation. This means that in the event of a safety-critical situation, the shutdown is reduced to what is necessary from a safety point of view, which increases system availability.
