    Exploiting Home Infrastructure Data for the good: Emergency Detection by reusing existing Data Sources

    [Accepted for publication]

    Advances in Intelligent Systems and Computing

    2021

    Abstract anzeigen

    Monitoring people within their residence can enable elderly to live a self-determined life in their own home environment for a longer period of time. Therefore commonly activity profiles of the residents are created using various sensors in the house. Deviations from the typical activity profile may indicate an emergency situation. An alternative approach for monitoring people within their residence we investigates within our research is reusing existing data sources instead of installing additional sensors. In private households there are already numerous data sources such as smart meters weather station routers or voice assistants available. Intelligent algorithms can be used to evaluate this data and conclude on personal activities. This in turn allows the creation of activity profiles of the residents without using external sensor technology.This work outlines the research gap in reusing existing data sources for Human Activity Recognition (HAR) and emergency detection which we intend to fill with our further work.

    Acceptance and Practically of Voice Assistance Systems in the everyday life of seniors: A study design

    [Accepted for publication]

    Advances in Intelligent Systems and Computing

    2021

    Abstract anzeigen

    Voice assistance systems (VAs) are becoming more popular. For Digital Natives these systems are almost part of everyday life. Does this technology also have the potential to facilitate access to digital services for persons aged 55+? Using the example of Amazon's "Echo" devices our research intends to provide a survey of the extent to which VAs are known to the target group how many elderly people own these systems and whether there are any reservations. In addition test persons will be investigated which form of interaction seems easiest for the solution of the tasks and how the operation of VAs differs from the operation of mobile devices to be learned and applied. The evaluation will include statements on socio-demographic and ethnographic aspects. Various Amazon Echo devices are installed in 20 senior households (and additionally in their family households) in order to test user acceptance and its benefits under real-world conditions.

    Activity-Monitoring in Private Households for Emergency Detection: A Survey of Common Methods and Existing Disaggregable Data Sources

    [Accepted for publication]

    Proceedings of the 14th International Joint Conference on Biomedical Engineering Systems and Technologies

    2021

    Abstract anzeigen

    Ambient-Assisted Living (AAL) technologies can enable the elderly people to live a self-determined life in their own home environment instead of hospitals and retirement homes for a longer period of time. Hence AAL systems are not only used for everyday support but also for the detection of potential emergency situ- ations and for triggering notification chains. For this purpose the people are usually continuously monitored within their residents by ambient or wearable sensors to detect deviations in their daily behavior.This work surveys common used technologies for Human Activity Recognition (HAR) / Human Presence De- tection (HPD) which is the basis for emergency detection. Furthermore by examining various home automa- tion software existing data sources from the residential infrastructure are identified that would be suitable for detecting personal activities.

    GeLaP: German Labeled Dataset for Power Consumption

    [Accepted for publication]

    Proceedings of the 6th International Congress on Information and Communication Technology

    2021

    Abstract anzeigen

    Due to the increasing spread of smart meters numerous researchers are currently working on disaggregating the power consumption data. This procedure is commonly known as Non-Intrusive Load Monitoring (NILM). However most approaches to energy disaggregation first require a labeled dataset to train these algorithms.In this paper we present a new labeled power consumption dataset that was collected in 20 private households in Germany between September 2019 and July 2020. For this purpose the total power consumption of each household was measured with a commercial available smart meter and the individual consumption data of 10 selected household appliances were collected.

    Hybrid-process-chain for polishing optical glass lenses – HyoptO

    Proceedings of SPIE Optical Engineering + Applications (24 August - 04 September, 20208; Optical Manufacturing and Testing XIII; online conference), San Diego, United States, vol. 11487

    2020

    DOI: 10.1117/12.2568400

    Abstract anzeigen

    A number of process steps that build on one another are required to manufacture optical components from glass. The polishing steps are the most time-consuming and therefore cost-intensive parts of the process chain. Low removal rates and the depth of the Sub Surface Damage (SSD) to be removed contribute to this. An alternative for the complete removal of the SSD-penetrated material using contactless polishing methods such as Ion Beam Figuring (IBF) is the healing of the SSD. Due to the induced energy during laser-polishing, the material is remelted at the defects and the SSD are closed. However, laser-polishing is also associated with disadvantages in terms of shape accuracy and surface quality. The project HyoptO is therefore devoted to the development of a hybrid-process-chain consisting of laser processing and conventional polishing. It is expected that the healing times of the SSD can significantly reduce the process times in the subsequent polishing steps. However, there are a few questions to be answered regarding the economic use of the hybrid-process-chain. These include:

    Multisensor UAV System for the Forest Monitoring

    Proceedings of the 2020 10th International Conference on Advanced Computer Information Technologies (ACIT) [September 6-8, 2020; Deggendorf]

    2020

    DOI: 10.1109/ACIT49673.2020.9208993

    Abstract anzeigen

    In recent years, unmanned aerial vehicles (UAV) of various shapes, sizes and functions have been increasingly used for civilian applications in a wide range of fields. UAVs are flexible, inexpensive, with the ability to carry high resolution sensing systems. UAVs fill the gap between manned aircraft and satellite remote sensing systems. When searching for new methodologies, especially in forestry research, UAVs are a unique platform. Remote forest sensing, forest mapping, forest precise measurement, forest fire monitoring and support for intensive forest management are areas in which remote sensing is fully utilized. The advantages of remote sensing are mainly low material and operating costs, flexible space and time deployment, and high intensity data collection. In order to move remote sensing applications from the experimental phase into real deployment, it is necessary to come up with new methodologies that can be determined using UAVs.

    Education 4.0: IoT- und CoP-unterstützte Smarte E-Learning Prozesse

    Tagungsband zum 19. E-Learning-Tag der FH JOANNEUM: Innovation & Reflexion – Henne oder Ei? , vol. 130

    2020

    Abstract anzeigen

    Studierende erleben im Lernmanagementsystem (LMS) „Moodle“ smarte E-Learning Prozesse in Mathematik- und Wissensmanagement-Kursen. „Smartes E-Learning“ besteht in Anlehnung an „smarte Produkte“ aus einer physischen, einer intelligenten und einer Vernetzungs-Komponente. Vernetzt sind die StudentInnen mit dem LMS einerseits in „Communities of Practice“ (CoP) zur Reflexion und andererseits über die Sensoren ihrer Smartphones oder Smartwatches (physische Komponente). Damit lässt sich dieses Lernumfeld der Kategorie “Internet of Things” (IoT) zuordnen. Im Lernprozess können die eingebetteten Sensoren mit den Biosignalen „Puls“ (HR) und „Herzfrequenzvariabilität“ (HRV) zur Selbstreflexion der Lernenden, zur Steuerung des Lernsystems und zur Personalisierung des Nutzungserlebnisses dienen. Erste Tests fanden u.a. Korrelationen zwischen erreichten Punkten in den Kontrollfragen und den Werten der Biosignale. Als intelligente Komponenten sind BenutzerInnenmodellierung, Chatbot, maschinelles Lernen usw. bei „Education 4.0“ im Einsatz.

    Education 4.0: An Adaptive Framework with Artificial Intelligence, Raspberry Pi and Wearables- Innovation for Creating Value

    Proceedings of the 2020 IEEE 26th International Symposium for Design and Technology in Electronic Packaging (SIITME)

    2020

    DOI: 10.1109/SIITME50350.2020.9292148

    Abstract anzeigen

    The Education 4.0 process can be used to foster students' performance, to motivate them by means of adaptive and personalized learning, to automate answering routine questions and to improve the quality of online examinations. It releases teachers from routine tasks, and it enables them to be more involved in the individualization of the educational process and in innovation. We apply artificial intelligence methodology to motivate students to improve their performance, and to identify early in course which students are at-risk of dropping out. In the adaptive Education 4.0 loT framework, the environmental and embedded sensors from wearables examine biosignals with biofeedback, such as pulse (HR) and heart rate variability (HRV), thereby increasing students' self-reflection, and allowing for a more personalized learning experience. The first experiments corroborate meaningful correlations between the data-points reached in the self-assessments, and values of the biosignals.

    Education 4.0: Smart Blended Learning assisted by Artificial Intelligence, Biofeedback and Sensors

    Proceedings of the 2020 IEEE 14th International Symposium on Electronics and Telecommunications (ISETC2020)

    2020

    DOI: 10.1109/ISETC50328.2020.9301034

    Abstract anzeigen

    The paper presents smart blended learning for fostering students’ performance. It uses models of student activity and detects causes of a possible drop out, using learning analytics and real-time data. Taking advantage of embedded sensors (non-invasive, low-cost, flexible and distraction free) built into wearable devices real-time data can be used to support students’ success, well-being and health. In our contribution to the research topic we evaluate the students' experience with smart blended learning using biofeedback methods, sensor data extracted from wearables for five specific lectures, during study periods and in examinations. The preliminary results indicate a correlation between the physiological signals and the grades in examination.

    2020

    DOI: 10.1109/EPEPS48591.2020.9231382

    Abstract anzeigen

    This paper presents a new cost-effective method to produce air-filled waveguides out of a printed circuit board (PCB) with a milling machine and how to implement them with standard PCB technology. For this purpose, low cost substrates like FR-4 are used. For the baseboard to waveguide transition in the E-Band (60-90GHz) a WR12 waveguide connector [1] was used. The WR12 waveguide was manufactured and analyzed on mechanical deviations. The RF performance in the E-Band was measured and compared to common PCB waveguides like microstrip lines (MS) and grounded coplanar waveguides (GCPW).

    Extracting Complex PCB Substrate Permittivity from a Transmission Line using the Finite Difference Integral Method from 10 GHz - 100 GHz

    [Invited Talk]

    Proceedings of the 2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)

    2020

    DOI: 10.1109/IMWS-AMP49156.2020.9199738

    Abstract anzeigen

    This paper presents a new numerical method to deduce the complex permittivity εr of PCB (printed circuit board) substrates. First, the attenuation and phase of an on board transmission line are measured with a vector network analyzer (VNA). The transmission line is then simulated with the finite difference integral method (FDI) with the substrate substituted by air. The measured and simulated phases are used, to calculate the effective permittivity and the real part of the complex permittivity εr ' . With known εr ' , the electromagnetic field distribution can be calculated, which is necessary to deduce the imaginary part of the permittivity. The shown algorithms can be used for frequencies up to 100 GHz and without any iterative processes.

    Simulation and Measurement of PCB Crossover Structures from DC up to 70 GHz

    [Invited Talk]

    Proceedings of the 2020 German Microwave Conference (GeMiC) [9-11 March 2020; Cottbus]

    2020

    Abstract anzeigen

    In this paper, 4 different crossover structures in a 6-layered printed circuit board (PCB) for high operation frequencies are presented. The design for all structures is based on grounded coplanar waveguide (GCPW). Two fully planar structures, a quasi-coaxial transition and coaxial transition are realized and have a measured bandwidth from DC to 50 GHz and DC to 60 GHz, respectively. Moreover, two structures are designed in submount technology. Especially the connection between baseboard and package (solder junction) plays an important role to guarantee best signal integrity. Therefore, the quality of the solder junction is analysed in detail with TDR (time domain reflectometry) measurement as well as with X-ray images. The submount transitions show good radio frequency (RF) characteristics from DC to 70 GHz.

    First steps towards an automated polishing process chain using one robot

    Proceedings of SPIE 11478 (Seventh European Seminar on Precision Optics Manufacturing [8 July 2020; Teisnach]), Bellingham, WA, USA

    2020

    DOI: 10.1117/12.2564840

    Abstract anzeigen

    Manufacturing precision optics is a complex process chain, which requires many operations on different machines. This is combined with operator-dependent steps such as manual cleaning, loading and measuring. In order to realize this process chain on a smaller shop area and to achieve a higher level of automation we build an operator-independent polishing cell. In this cell, an ABB robot serves as the actuator handling the workpiece. We positioned the robot in the center of the polishing cell to operate several workstations, so the whole process chain works with one single actuator. This arrangement allows a smaller and cheaper system, since no additional handling is required.
