Boris Brandherm, Matthieu Deru, Alassane Ndiaye, Gian-Luca Kiefer, Jörg Baus, Ralf Gampfer
Published in: Data Science anwenden Einführung, Anwendungen und Projekte - 2021 - Springer Verlag - ISBN: 978-3-658-33812-1

Abstract

In Deutschland entspricht die heutige Übertragungsnetztopologie häufig noch dem technischen Stand des einseitigen Energieflusses von zentralen Kraftwerken zu den Verbrauchern. Die Energiewende mit dem Ausstieg aus den Kernkraftwerken bis 2022 und dem Ausbau der erneuerbaren Energien auf Verteilnetzebene konfrontiert Niederspannungsnetze mit Herausforderungen wie z. B. unüberwachten Überlastungen oder Verletzungen des Spannungsbereichs.

Tarek Safi, Loay Daas, Gian-Luca Kiefer, Mansi Sharma, Alassane Ndiaye, Matthieu Deru, Jan Alexandersson, Berthold Seitz
Published in: Corneas. Klin Monbl Augenheilkd. 2021 Jun;238(6):680-687. English. doi: 10.1055/a-1498-1846. Epub 2021 Jun 22. PMID: 34157770.

Abstract

Cornea guttata may not be recognized in the eye bank and recent studies have displayed that guttae are transplanted in about 15% of cases in varying severities. The purpose of this study was to establish semiquantitative criteria for the detection of cornea guttata in donor corneas in the eye bank. In this retrospective cohort study, preoperative endothelial pictures of donor corneas were collected and classified according to the post-penetrating keratoplasty cornea guttata grade into three distinct groups: group 1 consists of healthy corneas with no guttae (guttata grade 0); group 2 constitutes corneas with mild asymptomatic cornea guttata (guttata grade +); and group 3 comprises corneas with advanced widespread cornea guttata (guttata grade ++/+++/++++). The preoperative pictures of each group were then individually analyzed using the following five semiquantitative criteria: The number and the area of the cell-depleted surfaces, the presence of less than 50% of the cells having a hexagonal or a circular shape, the presence of cell membrane defects and interruptions, the presence of blebs in the cell membrane, and the presence of groups of cells with a distinct whitish color.

🧾Forecast Quality of Physics-based and Data-driven PV Performance Models for a Small-scale PV System

Moritz Stüber, Felix Scherhag, Matthieu Deru, Alassane Ndiaye, Muhammad Moiz Sakha, Boris Brandherm, Jörg Baus and Georg Frey
Published in: Frontiers in Energy Research 9, 108

Abstract

In the context of smart grids, the need for forecasts of the power output of small-scale photovoltaic (PV) arrays increases as control processes such as the management of flexibilities in the distribution grid gain importance. However, there is often only very little knowledge about the PV systems installed: even fundamental system parameters such as panel orientation, the number of panels and their type, or time series data of past PV system performance are usually unknown to the grid operator. In the past, only forecasting models that attempted to account for cause-and-effect chains existed; nowadays, also data-driven methods that attempt to recognize patterns in past behavior are available. Choosing between physics-based or data-driven forecast methods requires knowledge about the typical forecast quality as well as the requirements that each approach entails. In this contribution, the achieved forecast quality for a typical scenario (day-ahead, based on numerical weather predictions [NWP]) is evaluated for one physics-based as well as five different data-driven forecast methods for a year at the same site in south-western Germany. Namely, feed-forward neural networks (FFNN), long short-term memory (LSTM) networks, random forest, bagging and boosting are investigated. Additionally, the forecast quality of the weather forecast is analyzed for key quantities. All evaluated PV forecast methods showed comparable performance; based on concise descriptions of the forecast approaches, advantages and disadvantages of each are discussed. The approaches are viable even though the forecasts regularly differ significantly from the observed behavior; the residual analysis performed offers a qualitative insight into the achievable forecast quality in a typical real-world scenario.

Azad, Schaugar, Schnittmann Evgeny, Ludwig Marcel, Zdrallek Markus, Zimpel Julian, Schalk Alexander, Brandherm Boris, Deru Matthieu, Ndiaye Alassane, Neusel-Lange Nils
Published in: 2019 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe)

Abstract

This article first examines the role of a Smart Meter as a supplier of measurement data for a Smart Grid. Based on this, future scenarios in which different granularities of smart meter data are available are described. In this context, the necessity for scenario-specific concepts for the integration of the different granularity levels of smart meter data is emphasized. Target-oriented concepts for the use of scenario-specific smart meter data are then presented together with simulative validation. It will be shown how and in what form smart meters offer added value for decentralized distribution grid automation systems. Finally, the limits and advantages of smart meter data will be discussed and summarized. With the aim of conceptualizing a blueprint for the entire European Union, the experiences of the project partners of the SINTEG showcase project DESIGNETZ flow together in this article to provide a cross-competence aggregation of the existing know-how.

🧾autoUI-ML: A Design Language for the Flexible Creation of Automotive GUIs Based on Semantically Represented Data

Matthieu Deru, Robert Neßelrath
Published in: Proceedings of the 4th International Symposium on Pervasive Displays, Pages 235-236, Saarbrücken, Germany, ACM, 2015

Abstract

We propose an XML-based user-interface markup language for prototyping and designing graphical user interfaces (GUI) in the automotive domain, called autoUI-ML. This markup language will help to accelerate and optimize the development workflow for both, designers and HCI developers. Furthermore the language implicitly constitutes an interface to the semantic based multimodal dialog system SiAM-dp. The autoUI-ML provides a high variability and offers the possibility to integrate an own corporate design. Moreover, the seamless and flexible connection of autoUI-ML to state-of-the-art rendering solutions allows the generation of professional and modern graphical user interfaces.

Abstract

The increasing complexity and flexibility in future production environments leads to huge amounts of data and the difficulty to analyze them in order to react to short-termed events. To tackle this challenge, an electronic performance board and editor was developed that allows users to create dashboards with proper visualizations of production data. This information can be shared among stakeholders and might be displayed on various devices, from personal tablets up to large public screens in the factory hall.

🧾Foundations of Semantic Television – Design of a Distributed and Gesture-Based Television System

Simon Bergweiler, Matthieu Deru
Published in: Freimut Bodendorf (ed.):International Journal on Advances in Intelligent Systems volume 8 number 1&2, Pages 194-208, IARIA, 7/2015

Abstract

The innovations in information and communication technologies change our daily life and the way how to interact with intelligent systems. Powerful computers are becoming smaller and are integrated almost anywhere, even in televisions. Today’s connected television systems are offering a lot of technical functionalities including these, which are currently integrated in smartphones. In this article, we describe an innovative approach in form of an intelligent television system named Swoozy, which enables viewers to discover extended information, such as facts, images, shopping recommendations or video clips about the currently broadcast TV program by using the power of technologies of the Internet and the Semantic Web. Via a gesturebased user interface viewers will get answers to questions they may ask themselves during a movie or TV report directly on their television. These questions are very often related to the name and vita of the featured actor, the place where a scene was filmed, or purchasable books and items about the topic of the report the viewer is watching. Furthermore, a new interaction concept for TVs is proposed using semantic annotations called Grabbables that are displayed on top of the videos and that provide a semantic referencing between the videos’ content and an ontological representation to access Semantic Web Services.

Abstract

🏆Best Paper Award - In this article, we describe an innovative approach to an intelligent television system named Swoozy that enables viewers to discover extended information such as facts, images, shopping recommendations or video clips about the currently broadcasted TV program by using the power of technologies of the Semantic Web (Web 3.0). Via a gesture-based user interface viewers will get answers to questions they may ask themselves during a movie or TV report directly on their television. In most cases, these questions are related to the name and vita of the featured actor, the place where a scene was filmed, or purchasable books and items about the topic of the report the viewer is watching. Furthermore, a new interaction concept for TVs is proposed using semantic annotations called “Grabbables” that are displayed on top of the videos and that provide a semantic referencing between the videos’ content and an ontological representation to access Semantic Web Services.

Abstract

We will show how to build innovative multimodal dialog user interfaces that integrate multiple heterogeneous web services as data sources on the basis of the Ontology-based Dialog Platform (ODP). More specifically, we will describe how to exploit ODP’s well-defined extension points and how generic ODP processing modules can be adopted, in order to support a rapid dialog system engineering process. By means of the latest ODP-based educational information system CIRIUS and the ODP workbench, a set of Eclipse-based editors and tools, we demonstrate step-by-step along the generic multimodal dialog processing chain what has to be done for developing a new multimodal dialog user interface for a specific application domain.

Abstract

This article gives an overview of the basic dialog shell for multimodal interaction that was created as the foundation for the software components developed in the Core Technology Cluster of the THESEUS research program. It explains the basic setup of systems based on the dialog shell for specific use cases. The general processing paradigm for interaction in our framework using semantic interface elements as well as several dialog phenomena handled by the dialog shell are described. Finally, a selection of different demonstrator systems that were built for a range of applications is presented briefly. They offer access to quite varied use case scenarios featuring multimodal input and output, including gestures, multi-touch, spoken input and output, and interactions across mobile and stationary devices.

🧾Novel Consumer-to-Product Interactions with Context-aware Embedded Platforms

Soenke Knoch, Matthieu Deru, Simon Bergweiler, Jens Haupert
Published in: HCI International 2014 – 01/2014: pages 513-524; , ISBN: 9783319074450

Abstract

In this work we suggest a new device to instrument everyday objects in the end-user life cycle phase that makes everyday life easier for the elderly. The instrumentation of products, such as food, transforms them into smarter and more intelligent products. The equipped product notifies the user when food is spoiled and—interconnected with other smart products—advises against side effects that occur when food is consumed while a certain medication is ingested. We describe the considerations that were made towards a first prototype from a technical perspective. An interaction model was developed, a requirements analysis performed and several design and development considerations made. An architecture shows the information flow between sensors, actuators, and the Internet of Things. In the end, the prototype of a product sleeve is presented that is easy to handle and intuitive to operate. A feedback study is planned in the near future.

🧾Enabling Data Collections for Open-Loop Applications in the Internet of Things

Alexander Kröner, Jens Haupert, Matthieu Deru, Simon Bergweiler, Christian Hauck
Published in: International Journal on Advances in Internet Technology 01/2014; 7:75-85.

Abstract

Using label technology, a physical object may be employed to build a continuously growing data collection, which can, for instance, be exploited for product quality monitoring and supply chain management. Along the object's life-cycle, queries to such a collection may stay quite similar, e.g., 'get unusual observations'. However, expectations to a 'good' answer may change, as with time different entities will come into contact with the object. This article reports on work in progress concerning a framework for collecting data about things, which aims at decoupling logic employed for interpreting such a collection from processing hardware and using the collection itself for transporting such logic. Main contributions include an approach to hardware-abstraction of processing logic at the object or remote, an app store for retrieving interpretation and presentation logic, and interaction forms with such memories.

🧾Milky: On-product App for emotional Product to Human Interactions

Matthieu Deru and Simon Bergweiler
Published in: Proceedings of the 15th International Conference on Human Computer Interaction with Mobile Devices and Services (MobileHCI 2013)

Abstract

In this paper we present a new way of emotional interaction with products. Based on the rapid prototyping Microsoft Gadgeteer platform, we concretized our vision of an on-product app by implementing an anthropomorphic intelligent milk carton. The purpose of this realization is to give customers a better view of a product's life-cycle. This realization also demonstrates that the frontier between pure mobile applications development and the creation of tangible objects is very thin and opens new way to integrate the Internet of Things over an anthropomorphic user interface, thus leading to a new product to human interaction form.

Published in: Proceedings of the International Conference on Artificial Intelligence (ICAI), Las Vegas, 2009

Abstract

We describe a Web 3.0 interaction system where the mobile user scenario is combined with a touchscreen-based collaborative terminal. Multiple users should be able to easily organize their information/knowledge space (which is ontology-based) and share information with others. We implemented a MP3 and video player interface for the physical iPod Touch (or iPhonej and the corresponding virtual touchscreen workbench. The Web 3.0 access allows us to organize and retrieve multimedia material from online repositories such as YouTube and LastFM.

🧾Motion-Based Adaptation of Information Services for Mobile Users

Mathias Bauer and Matthieu Deru
Published in: User Modeling 2005, 10th International Conference, UM 2005, Edinburgh, Scotland, UK, July 24-29, 2005, Proceedings; 01/2005

Abstract

Adaptive information systems typically exploit knowledge about the user’s interests, preferences, goals etc. to determine what should be presented to the user and how this presentation should take place. When dealing with mobile users, however, information about their motions—the places visited, the duration of stays, average velocity etc.—can be additionally exploited to enrich the user model and better adapt the system behavior to the user’s needs. This paper discusses the use of positioning data and background knowledge to achieve such a motion-based adaptation of information provision
