Get PDFMultivariate Demand Forecasting for Rental Bike Systems Based on an Unobserved Component Model
Get PDFMany German cities, municipalities and transport associations are expanding their bikesharing systems (BSS) to offer citizens a cost-effective and climate-friendly means of transport and an
alternative to private motorized transport (PMT). However, operators face the challenge of generating
high-quality predictive analyses and time series forecasts. In particular, the prediction of demand is a
key component to foster data-driven decisions. To address this problem, an Unobserved Component
Model (UCM) has been developed to predict the monthly rentals of a BSS, whereby the station-based
BSS VRNnextbike, including over 2000 bikes, 297 stations and 21 municipalities, is employed as an
example. The model decomposes the time series into trend, seasonal, cyclical, auto-regressive and
irregular components for statistical modeling. Additionally, the model includes exogenous factors
such as weather, user behavior (e.g., traveled distance), school holidays and COVID-19 relevant
covariates as independent effects to calculate scenario based forecasts. It can be shown that the
UCM calculates reasonably accurate forecasts and outperforms classical time series models such as
ARIMA(X) or SARIMA(X). Improvements were observed in model quality in terms of AIC/BIC (2.5%
to 22%) and a reduction in error metrics from 15% to 45% depending on the considered model.Gefördert durch den Publikationsfonds der Hochschule RheinMainPublished Versio
External Ellipsoidal Approximations for Set Evolution Equations
Get PDFIn many applications, uncertainty and imprecision in control systems require the focus on reachable sets instead of single state vectors. Then, closed-loop controls also refer to these attainable sets leading to a class of set evolution problems. We suggest sufficient conditions for its well-posedness and for approximating their solutions by intersections of finitely many time-dependent ellipsoids characterized by solutions to a system of ordinary differential equations.Gefördert im Rahmen des Projekts DEALPublished Versio

Entwicklung eines webbasierten Systems für interaktive Aufgaben zu Nassi-Shneiderman-Diagrammen in der Programmierausbildung
Get PDFMit Diagrammtypen wie dem Struktogramm lernen Programmieranfänger den Aufbau von Algorithmen und Programmcode. In der Ausbildung zum Fachinformatiker kommen dabei Übungsaufgaben vor, die von Lehrenden teilweise händisch gestellt, und von Lernenden gelöst werden müssen. Im Rahmen dieser Arbeit wurde ein System prototypisch konzipiert und umgesetzt, welches beim Erstellen und Lösen von Aufgaben zu Struktogrammen unterstützen soll. Dazu wurde eine Pseudocode-ähnliche Sprache als Domain Specific Language (DSL) mit dem Tool ANTLR4 entwickelt, mit welcher Lehrende Struktogramme im Rahmen der Aufgabenstellung effizient ausdrücken können. Für Lernende hingegen wurde ein intuitiver und interaktiver grafischer Editor auf der Basis von SVG umgesetzt, mit welchem sie Aufgaben ohne Vorkenntnisse lösen können. Dabei unterstützt das System drei unterschiedliche Aufgabentypen: das Erstellen neuer Struktogramme, das Kommentieren fehlerhafter Struktogramme und das Korrigieren fehlerhafter Struktogramme
Integration des Straßenpersonennahverkehrs in den Deutschlandtarif
Get PDFDas über den Sommer 2022 hinweg gültige 9-Euro-Ticket sorgte in erster Linie wegen des überdeutlichen Preissignals für breite mediale Aufmerksamkeit. Dabei bewirkte die gleichzeitig vollzogene, wenn auch nur vorübergehende deutschlandweite Tarifintegration mit dem straßengebundenen ÖPNV ebenfalls spürbare Erleichterungen auf der Nutzerseite. Eine kurz vor dessen Einführung fertiggestellte Untersuchung lotete anhand identifizierter Lücken und der Quantifizierung erzielbarer Nachfrageeffekte gestaffelter Integrationsschritte bereits die Potenziale einer dauerhaften Lösung zur umfassenden tariflichen Verknüpfung von Straße und Schiene aus.Published Versio
Theory and Practice of Socialisation of a Foreign Student as an Individual Using the Video Component of Media Education (The Case of Higher Education Institutions in the US and Germany)
Get PDFThe article considers the issue of the socialisation of foreign students and the use of the video
component of media education during this process. The article argues that socialisation in a new social
and cultural environment is essential in order to effectively build interpersonal academic and social
relationships. To this end, the purpose of the study is to analyse the practical use of the video component
of media education in higher education institutions of the US and Germany in the process of the
socialisation of foreign students as a necessary condition for social and academic activities. To achieve
this purpose, a number of research methods were applied, including analysis (categorising the process
of socialisation into aspects), synthesis (for a holistic view of the systemic nature of socialisation),
axiomatic (identifying provisions that do not require a proof), deduction (contributed to the development
of sequences for the process of using the video component of media education), induction (aimed at the
transformation of the designated sequences into systematic socialisation). The article considers the role
of socialisation for a foreign student as an individual, which includes the formation and development of
skills required for academic and social interpersonal interactions, including secondary socialisation
skills, which allows transforming the combination of primary and secondary socialisation skills into
practical activity in a new society. The practice of using the video component of media education at
universities of the US and Germany is studied. The article has found that the presentation of video
content should be accompanied by the subsequent discussion that provides clarification of social and
cultural and interpersonal aspects. The video content is focused on three directions: general (the purpose
of which is a superficial discussion and creation of a positive intra-group environment), professional
(includes discussions on any issues visualised in the video content) and informational (allowing for the
primary involvement of a foreign student in the academic and, less often, social issues of a host country).
The results obtained through analysing the higher education institutions selected for the study suggest
that there are similar approaches regarding the practice of using the video component of media education
in the socialisation of foreign students, which is expressed in the focus of the presented content on social
and cultural and interpersonal situations as well as and the development of linguistic skills. However,
the informational direction of the video component in educational institutions of Germany (among the
studied universities) should be noted
