    Human Presence Detection by monitoring the indoor CO2 concentration

    Tagungsband zur Konferenz Mensch und Computer 2020 (06.-09.09.2020; Magdeburg)

    Abstract anzeigen

    Presence detection systems are becoming more and more important and are used in smart home environments in the Ambient Assisted Living (AAL) domain or in surveillance technology. Common systems focus on using motion sensors or cameras which have only a limited viewing angle and therefore monitoring gaps can easily occur within a room. Humans produce carbon dioxide (CO2) through their respiration which is distributed in rooms. As a result if one (or more) persons are in a room a significant increase in CO2 concentration in the room can be noted. With this work we investigate an approach to detect the presence or absence of people indoors by monitoring the CO2 concentration in the ambient air.

    Organizational, Technical, Ethical and Legal Requirements of Capturing Household Electricity Data for Use as an AAL System

    Proceedings of the Fifth International Congress on Information and Communication Technology (ICPCCI 2019) [20-21 February 2020; London, UK]

    DOI: 10.1007/978-981-15-5856-6_38

    Abstract anzeigen

    Due to demographic change elderly care is one of the major challenges for society in near future fostering new services to support and enhance the life quality of the elderly generation. A particular aspect is the desire to live in one’s homes instead of hospitals and retirement homes as long as possible. Therefore it is essential to monitor the health status i.e. the activity of the individual. In our data-driven society data is collected at an increasing rate enabling personalized services for our daily life using machine-learning and data mining technologies. However the lack of labeled datasets from a realistic environment hampers research for training and evaluating algorithms. In the project BLADL we use data mining technologies to gauge the health status of elderly people. Within this work we discuss the challenges and caveats both from a technical and ethical perspectives to create such a dataset.

    Amazon Echo: A Benchmarking Model Review

    Proceedings of the 14th International Conference on Interfaces and Human Computer Interaction (23-25 July 2020; Zagreb, Croatia)

    Abstract anzeigen

    Smart speakers are becoming increasingly popular. The market leader for smart speakers are the products of the Echo family from Amazon. There are currently 9 different models with different technical specifications available in Germany. With this paper, the models was benchmarked against each other in terms of (i) speech recognition reliability, (ii) output sound pressure and (iii) power consumption in a laboratory experiment. Previous works in this area has only considered individual models of the product family. Significant differences in speech recognition accuracy, output sound pressure and power consumption were identified between the models. In general it was observed, that the Echo Show 8 model was the most efficient in terms of the above criterias.

    Data Privacy Management (DPM) - A Private Household Smart Metering Use Case

    [Accepted for publication]

    Tagungsband zum 6. Usable Security und Privacy Workshop im Rahmen der Konferenz Mensch und Computer 2020 (06.-09.09.2020; Magdeburg)

    Abstract anzeigen

    The automated collection of real life data in private households places special requirements on a Data Privacy Management (DPM) concept. The development and implementation of a DPM concept for use in a scientific environment is demonstrated according to a successful use case – the project BLADL. The intention of this paper is to provide a guideline for ethical and privacy-preserving data collection and management in research projects in the EU.

    Determination of tomato quality attributes using portable NIR-sensors

    Proceedings of OCM 2019: 4th International Conference on Optical Characterization of Materials (13-14 March, 2019; Karlsruhe), Karlsruhe

    ISBN: 978-3-7315-0864-9

    DOI: 10.5445/KSP/1000087509

    Abstract anzeigen

    As part of a research project a multidisciplinary approach of different research institutes is followed to investigate the possibility of using a commercially available miniaturized NIR-sensor for the determination of tomato fruit quality parameters in postharvest. Correlation of spectra and tomato reference values of firmness, dry matter and total soluble solids showed good prediction accuracy. Additionally the decline of firmness over storage time with respect to storage temperature of tomatoes could be modelled. Therefore, the decline of firmness as an indicator for shelf-life can be predicted using this portable NIR-Sensor.

    Monitoring 'lemons': Why lower productivity workers are sometimes monitored more closely

    Applied Economics Letters, no. Published: 18 June 2020

    DOI: 10.1080/13504851.2020.1776826

    Abstract anzeigen

    We analyse workplace monitoring in a principal–agent model with two types of workers who differ in their productivity. The firm decides on the effort level, the wage and the monitoring intensity for both workers. We find that the elasticities of the workers’ effort-cost function and the firm’s monitoring-cost function affect the firm’s monitoring intensity. Our results imply that the firm might monitor the low-productive worker more closely than the high-productive worker.

    Sustainable Peer-to-Peer Energy Trading Principles and Smart Meter Requirements for Smart Grids

    Bavarian Journal of Applied Sciences, vol. 5, no. 1, pp. 461-475

    DOI: 10.25929/bjas.v5i1.66

    Abstract anzeigen

    The sustainability and efficiency of the current and future power grid is an important topic nowadays. Thus, the increasing usage of renewable energy sources for generation of electricity requires a more complex infrastructure to manage generation and demand efficiently. In order to stabilize a power grid there are different methods to trade energy sources. Especially for smart grid infrastructures, the most interesting approach is to trade energy peer-to-peer. Thus, we consider different peer-to-peer principles in detail. Particularly, the underlying subsystem is essential for fast and accurate trading. That is why smart meters, forming the lowest layer of the system, are one of the most important parts within the grid infrastructure. Their main task is to provide high quality information and services for smart contracting and also for controlling the power grid with regard to efficiency and sustainability. The information provided by smart meters can also be used within a smart energy management to optimize production and consumption times. This demand side management approach helps to prevent overproduction and hence leads to more sustainablitiy in future decentralized power grids. For this purpose, peer-to-peer methods and smart meters have to fulfil dedicated requirements which are considered here in more detail.
