Vom 7. bis 9. Oktober 1998 war die Abteilung Produktionssysteme des Instituts Arbeit und Technik Gastgeber des EMISA-Fachgruppentreffens 1998 Integration von Mensch, Organisation und Technik: eine partielle Bilanz. Dieser Reader stellt eine Sammlung der Vorträge dar, die während des Fachgruppentreffens gehalten wurden. Die hier vorliegenden Fassungen gehen dabei aber über den Inhalt der Vorträge hinaus und beinhalten z.B. zusätzliches empirisches Material. Die Fachgruppe EMISA (Entwicklungsmethoden für Informationssysteme und deren Anwendung) im Fachbereich "Softwaretechnologie und Informationssysteme" der Gesellschaft für Informatik e.V. (GI) veranstaltet jährlich Fachgruppentreffen, bei der Mitglieder der Fachgruppe, aber auch interessierte Anwender und Fachleute aus Industrie und Wissenschaft sich zu einem speziellen Themengebiet austauschen. Thematisch ist die Konferenz Bestandteil einer Veranstaltungsreihe, die von der Arbeitsgruppe "Modellierung in soziotechnischen Systemen" der Fachgruppe EMISA durchgeführt und von Prof. Dr. Erich Ortner (TU Darmstadt) und Dr.-Ing. Hansjürgen Paul (Institut Arbeit und Technik) moderiert wird.From 7 to 9 October 1998 the Production Systems Department of the Institute for Work and Technology was host of the EMISA conference Integration of Men, Organisation and Technology: A Partial Result. This reader comprises the presentations given by the authors in extended versions, e.g. including additional statistical material. The special interest group EMISA (Development Methods for Information Systems and their Application) within the department Software Technology and Information Systems of the German Computer Society (GI) holds annual meetings, where members of the special interest group and interested guests from science and industry discuss selected topics. This conference is one of several meetings organized by the working group "Modelling in Sociotechnical Systems" of the special interest group EMISA. The working group is moderated by Prof. Dr. Erich Ortner (TU Darmstadt) and Dr.-Ing. Hansjürgen Paul (Institute for Work and Technology)

Quantification and mitigation of the instrument effects and uncertainties of the airborne limb imaging FTIR GLORIA

The Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) is an infrared imaging FTS (Fourier transform spectrometer) with a 2-D infrared detector that is operated on two high-flying research aircraft. It has flown on eight campaigns and measured along more than 300 000 km of flight track.This paper details our instrument calibration and characterization efforts, which, in particular, almost exclusively leverage in-flight data. First, we present the framework of our new calibration scheme, which uses information from all three available calibration sources (two blackbodies and upward-pointing “deep space” measurements). Part of this scheme is a new algorithm for correcting the erratically changing nonlinearity of a subset of detector pixels and the identification of the remaining bad pixels.Using this new calibration, we derive a 1σ bound of 1 % on the instrument gain error and a bound of 30 nW cm−2 sr−1 cm on the instrument offset error. We show how we can examine the noise and spectral accuracy for all measured atmospheric spectra and derive a spectral accuracy of 5 ppm on average. All these errors are compliant with the initial instrument requirements.We also discuss, for the first time, the pointing system of the GLORIA instrument. Combining laboratory calibration efforts with the measurement of astronomical bodies during the flight, we can achieve a pointing accuracy of 0.032∘, which corresponds to one detector pixel.The paper concludes with a brief study of how these newly characterized instrument parameters affect temperature and ozone retrievals. We find that the pointing uncertainty and, to a lesser extent, the instrument gain uncertainty are the main contributors to the error in the result

Data-driven analysis of interactions between people with dementia and a tablet device

Abstract In the project I-CARE a technical system for tablet devices is developed that captures the personal needs and skills of people with dementia. The system provides activation content such as music videos, biographical photographs and quizzes on various topics of interest to people with dementia, their families and professional caregivers. To adapt the system, the activation content is adjusted to the daily condition of individual users. For this purpose, emotions are automatically detected through facial expressions, motion, and voice. The daily interactions of the users with the tablet devices are documented in log files which can be merged into an event list. In this paper, we propose an advanced format for event lists and a data analysis strategy. A transformation scheme is developed in order to obtain datasets with features and time series for popular methods of data mining. The proposed methods are applied to analysing the interactions of people with dementia with the I-CARE tablet device. We show how the new format of event lists and the innovative transformation scheme can be used to compress the stored data, to identify groups of users, and to model changes of user behaviour. As the I-CARE user studies are still ongoing, simulated benchmark log files are applied to illustrate the data mining strategy. We discuss possible solutions to challenges that appear in the context of I-CARE and that are relevant to a broad range of applications.</jats:p

Anaesthetic protocol for paediatric glaucoma examinations: the prospective EyeBIS Study protocol

INTRODUCTION: Neonates and young infants with diagnosed or highly suspected glaucoma require an examination under anaesthesia to achieve accurate intraocular pressure (IOP) measurements, since crying or squinting of the eyes may increase IOP and lead to falsely high values. IOP considerably depends on perioperative variables such as haemodynamic factors, anaesthetics, depth of anaesthesia and airway management. The aim of this paper is to report the design and baseline characteristics of EyeBIS, which is a study to develop a standardised anaesthetic protocol for the measurement of IOP under anaesthesia in childhood glaucoma, by investigating the link between the magnitude of IOP and depth of anaesthesia. METHODS AND ANALYSIS: This is a single-centre, prospective cohort study in 100 children with diagnosed or highly suspected glaucoma all undergoing ophthalmological examination under general anaesthesia. 20 children, who undergo general anaesthesia for other reasons, are included as controls. The primary outcome measure is the establishment of a standardised anaesthetic protocol for IOP measurement in childhood glaucoma by assessing the relationship between IOP and depth of anaesthesia (calculated as an electroencephalography variable, the bispectral index), with special emphasis on airway management and haemodynamic parameters. The dependence of IOP under anaesthesia on airway management and haemodynamic parameters will be described, using a mixed linear model. Restricting the model to patients with healthy eyes will allow to determine a 95% reference region, in which 95% of the measurement values of patients with healthy eyes can be expected. ETHICS AND DISSEMINATION: The study has been approved by the local ethics committee of the Medical Association of Rhineland-Palatine (Ethik-Kommisssion der Landesaerztekammer Rheinland-Pfalz), Germany (approval number: 2019-14207). This work will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at national and international scientific meetings and data sharing with other investigators.
