Machines as teammates: A research agenda on AI in team collaboration
(2019-07-06)
What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. ...

Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2020)
Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary ...

A unified and memory efficient framework for simulating mechanical behavior of carbon nanotubes
(2015-06-01)
Carbon nanotubes possess many interesting properties, which make them a promising material for a variety of applications. In this paper, we present a unified framework for the simulation of the mechanical behavior of carbon nanotubes. It allows the creation, simulation and visualization of these structures, extending previous work by the research group “MISMO” at TU Darmstadt. In particular, we develop and integrate a new matrix-free iterative solving procedure, employing the conjugate gradient method, that drastically ...

Process is King: Evaluating the Performance of Technology-mediated Learning in Vocational Software Training
(2018-09-01)
Technology-mediated learning (TML) is a major trend in education, since it allows to integrate the strengths of traditional- and IT-based learning activities. However, TML providers still struggle in identifying areas for improvement in their TML offerings. One reason for their struggles is inconsistencies in the literature regarding drivers of TML performance. Prior research suggests that these inconsistencies in TML literature might stem from neglecting the importance of considering the process perspective in ...

Eine SPARQL-Schnittstelle für OData-Services
(2014-11-25)
Enterprise-Resource-Planning-Systeme (ERP-Systeme) bilden für die meisten mittleren und großen Unternehmen einen essentiellen Bestandteil ihrer IT-Landschaft zur Verwaltung von Geschäftsdaten und Geschäftsprozessen. Geschäftsdaten werden in ERP-Systemen in Form von Geschäftsobjekten abgebildet. Ein Geschäftsobjekt kann mehrere Attribute enthalten und über Assoziationen zu anderen Geschäftsobjekten einen Geschäftsobjektgraphen aufspannen. Existierende Schnittstellen ermöglichen die Abfrage von Geschäftsobjekten, ...

20. Theorietag der GI-Fachgruppe "Automaten und Formale Sprachen"
(2010-11-05)
Die Fachgruppe AFS (früher Fachgruppe 0.1.5) der Gesellschaft für Informatik
veranstaltet seit 1991 einmal im Jahr ein Treffen der Fachgruppe im Rahmen eines Theorietags, der traditionell eineinhalb Tage dauert. Seit dem Jahr 1996 wird dem eigentlichen Theorietag noch ein eintägiger Workshop zu speziellen Themen der theoretischen Informatik vorangestellt.
In diesem Jahr wurde der Theorietag vom Fachgebiet "Theoretische Informatik"
des Fachbereichs Elektrotechnik/Informatik der Universität Kassel organisiert. Er ...

Dynamische Konfiguration verteilter Informationsverarbeitung in Gruppen heterogener Agenten
(2018-03-22)
Das erfolgreiche Agieren von Multiagentensystemen (MAS) setzt eine umfangreiche und hochwertige Wissensbasis voraus. Die Wissensbasis umfasst die von einem Agenten benötigten Informationen, welche durch die Verarbeitung von Sensorinformationen erzeugt werden. Die Anpassung der Informationsverarbeitung an die Einsatzdomäne ermöglicht es, die Qualität der Wissensbasis zu gewährleisten und so die Leistung des MAS zu steigern. Aktuelle Middleware-Systeme unterstützen die Integration von gängigen Methoden und Verfahren ...

Self-Healing in Autonomous Robot Teams
(2017-05-24)
Today, robots are used in nearly every type of automated manufacturing and assembly process. Robot installations typically apply static actuator systems in clearly structured environments. These systems show impressive abilities in speed and accuracy for repetitive manipulation tasks. Future automation applications, however, require an increasing level of flexibility, where classical systems reach their physical limits. As a reaction, robots become mobile, intelligent and cooperative. These new characteristics, ...

Context as a Service
(2013-03-22)
In the vision of Mark Weiser on ubiquitous computing, computers are disappearing from the focus of the users and are seamlessly interacting with other computers and users in order to provide information and services. This shift of computers away from direct computer interaction requires another way of applications to interact without bothering the user. Context is the information which can be used to characterize the situation of persons, locations, or other objects relevant for the applications.

Information Exchange and Fusion in Dynamic and Heterogeneous Distributed Environments
(2010-12-10)
Context awareness, dynamic reconfiguration at runtime and heterogeneity are key characteristics of future distributed systems, particularly in ubiquitous and mobile computing scenarios. The main contributions of this dissertation are theoretical as well as architectural concepts facilitating information exchange and fusion in heterogeneous and dynamic distributed environments. Our main focus is on bridging the heterogeneity issues and, at the same time, considering uncertain, imprecise and unreliable sensor information ...
