  • Publikation: Instandhaltung 4.0: versprochen – gehalten?

    Vor zehn Jahren wurde mit der Roadmap der Instandhaltung 4.0 eine Initiative gestartet, die die Auswirkungen von Industrie 4.0 auf die Instandhaltung und die Bedürfnisse der Branche systematisch erfasste und entsprechende Handlungsanweisungen ableitete. Dieses Jubiläum nehmen wir zum Anlass nachzufragen, was von den Versprechungen der digitalen Transformation in der Instandhaltung in den letzten zehn Jahren geblieben ist: Letztlich waren auch die Instandhaltungstage immer am Puls der digitalen Transformation und die dort vorgestellten Themen und Schulungen bieten ein Spiegelbild der Entwicklung der digitalen Transformation.

  • Publikation: Digital Transformation Accelerator Design and Challenges for Cooperation between RTOs and Technology-based SMEs and Start-ups

    In this contribution, we will explore theory-based approaches to accelerator programs and innovation intermediaries that help to best design effective collaboration between start-ups (small and medium enterprise-sized), research and technology organizations (RTOs) and innovative companies. These are loosely connected as partners in an emerging organizational form: European Digital Innovation Hubs (EDIHs). Which success factors identified in previous accelerator programs could play a critical role in the success of an EDIH in this specific industry? How can the impact of EDIH accelerator services be measured in forthcoming evaluations? The article is structured as to first provide the background to the roughly 150 European innovation support networks, initiated by the European Commission (EC) during 2021 and coordinated by RTOs with different technological expertise. Based on the description of the intended accelerator function to be performed by an EDIH, some conceptual theoretical considerations are presented in a second step, which shed light on central aspects of the research […]

  • Post: Transmission Quality of Intercom Functions

    The transition to increasing wireless communication networks significantly changes their characteristics. Salzburg Research develops a measurement system for network quality for Commend International. Commend International GmbH, a globally recognized major supplier of integrated intercom systems, has been developing and manufacturing security and communication solutions for the protection of people, buildings and property for over 50 years. In order to remain at the forefront of digital developments, the company relies on collaboration with researchers. Communication networks are becoming increasingly heterogeneous: where historically only wired networks were used, mixed forms or even completely wireless networks are being implemented more often. This opens up new application possibilities, but also significantly changes the properties of communication networks. On behalf of Commend, Salzburg Research is investigating a suitable monitoring of the performance characteristics of communication networks necessary for intercom functions and how 5G mobile networks influence these performance characteristics. The measurement system for voice/video data streams supports the reliable […]

  • Publikation: An Open Data Set about Multi-Provider Redundancy in Cellular Networks

    More and more applications are benefiting from the ever-increasing performance of wireless communication. Certain use cases in the mobility area (e.g. autonomous driving) demand particularly high reliability, which can be achieved through redundant transmission. In practice, however, it can be difficult to measure and study the precise benefit of redundancy for reliability and therefore, appropriate publicly available data sets are desirable. We provide such a data set about multi-provider redundancy in cellular networks: the performance metrics of redundant transmission channels are measured from a driving car, thus taking mobility into account. A statistical evaluation quantifies the effect of correlation on reliability empirically. In the future, this data set can be used for more detailed and elaborate investigations of the influence of redundancy on reliability. The knowledge thus obtained, about the interaction between redundancy and reliability helps to make new safety- and time-critical applications amenable to wireless communication.

  • Publikation: Traffic Prediction of Real Network Traffic Data with LSTM Neural Networks

    The aim of this work is to make time series predictions for real network traffic data by using long short-term memory neural networks (LSTMs). The data used for this work was captured in an office environment by a company from the field of network security and monitoring. The trained LSTMs are compared to baseline methods which have lower training costs. It is shown that the relative performance of LSTM-based predictions depends on the composition of the data. For aggregated traffic, the analyzed time series contains regular patterns with no big gaps and the trained LSTM outperformed baseline methods with an NRMSE of 0.072. In case of non-aggregated traffic of single clients/services with more gaps, jumps or steep trends within the time series, baseline methods can outperform LSTMs. Out of the used baseline methods, the ARIMA method shows the best performance in most experiments. Finally, it is also shown how the traffic predictions can be […]

  • Publikation: Elicitation and Formalization of Local Energy Community Stakeholder Requirements in Austria.

    Local energy communities (LECs) are quickly gaining popularity and have considerable potential to benefit their participants as well as the overall energy system, but they may also have a destabilizing effect if implemented in an uncoordinated fashion. Project ECOSINT aims to develop a unified and modular information and communications technology (ICT) architecture for seamless, large-scale integration of LECs into the overall energy system in to ensure that their benefits can be fully lifted. Following a holistic approach, this process involved the elicitation and formalization of requirements from all involved stakeholders as a basis for the development of this architecture. This paper outlines, how these requirements have been collected and formalized using state of the art methods. Furthermore, the requirements are presented and examples of the results of the formalization process are given.

  • Publikation: Estimating 5G Cell Utilization by Passive Measurement: A Machine Learning Approach

    Utilization of a mobile communication cell’s physical resources is a crucial impact factor on the data rate and quality of service available to a network user. Information about the utilization is therefore of great interest to researchers and network providers. Measurement scenarios that should be carried out independent of network providers require a measurement method that does not depend on a connection to a base station. In this work, we propose a novel estimation algorithm and introduce a measurement tool based on this algorithm, which is able to estimate the utilization of a 5G cell’s physical resources without being connected to a base station. The proposed estimation algorithm is a two-step machine learning algorithm, based on Expectation-Maximization. An off-the-shelf software-defined radio is used for the implementation of the measurement tool, making it inexpensive and widely applicable. The measurement method is entirely passive and does not depend on any connection to the network, making it completely […]

  • Publikation: Industrial Communication with Semantic Integration Patterns

    AbstractDigital twins have emerged as a key technological concept in the manufacturing industry. They form an information hub for industrial equipment and interact with dedicated applications in the operational manufacturing network. Digital twins consume and deliver information from machines to basically all connected applications. This results in complex integration requirements. The paper builds on previously designed semantic interoperability concepts for datadriven digital twins. It gives an overview of semantic data integration standards and provides insights into the current implementation of semantic integration patterns. Based on the challenges of the underlying research project “i-Twin”, semantic integration patterns provide standardized communication channels for operational management systems and connected assets. They build on the services of the semantic data integration middleware and use semantic connectors to bridge the proprietary data objects with an I4.0 compliant information model based on the asset administration shell (AAS). Semantic integration patterns will reduce the integration effort for equipment manufacturers and software providers, […]
