Classifying Smart Personal Assistants: An Empirical Cluster Analysis
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The digital age has yielded systems that increasingly reduce the complexity of our everyday lives. As such, smart personal assistants such as Amazon’s Alexa or Apple’s Siri combine the comfort of intuitive natural language interaction with the utility of personalized and situation-dependent information and service provision. However, research on SPAs is becoming increasingly complex and opaque. To reduce complexity, this paper introduces a classification system for SPAs. Based on a systematic literature review, a ...

Alexa, Can You Help Us Solve This Problem? How Conversations With Smart Personal Assistant Tutors Increase Task Group Outcomes
(Association for Computing Machinery, 2019)
Despite a growing body of research about the design and use of Smart Personal Assistants, existing work has mainly focused on their use as task support for individual users in rather simple problem scenarios. Less is known about their ability to improve collaboration among multiple users in more complex problem settings. In our study, we directly compare 21 groups who either use a Smart Personal Assistant tutor or a human tutor when solving a problem task. The results indicate that groups interacting with Smart ...

Insights into Using IT-Based Peer Feedback to Practice the Students Providing Feedback Skill
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The skills students need nowadays have changed over the last decades. The required skills are shifting more and more towards higher order thinking skills, such as critical thinking, collaboration and communication. One of the main ways of practicing these skills is through formative feedback, which consists of self-assessment and peer-assessment in our setting.
However, today’s lecturers are facing the challenge that the number of students per lecture is continuously increasing, while the available budget is stagnating. ...

Towards Empowering Educators to Create their own Smart Personal Assistants
(ScholarSpace, 2020)
Despite a growing body of research about the design and use of Smart Personal Assistants such as Amazon’s Alexa or Google’s Assistant, little is known about their ability to help educators offering individual support in large-scale learning environments. Smart Personal Assistant ecosystems empower educators to develop their own agents without deep technological knowledge. The objective of this paper is to design and validate a method that helps educators to create Smart Personal Assistants as learning tutors. Using ...

Historische Pragmatik und historische Varietätenlinguistik. Traditionen, Methoden und Modelle in der Romanistik
(Universitätsverlag Göttingen, 2005)
Der Ausgangspunkt für die Planung einer Sektion, die historische Pragmatik und historische Varietätenlinguistik zusammenführt, war die Beobachtung, dass beide Disziplinen sich in Forschungsgegenständen und Methoden eng berühren, als Forschungstraditionen jedoch nur in einem zufällig-anekdotischen Austausch miteinander stehen. Diese Zurückhaltung lässt sich sicherlich mit den unterschiedlichen Wegen erklären, auf denen sich historische Varietätenlinguistik und historische Pragmatik konstituiert haben (und die sich oft ...

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 ...

Beyond Ritz-Galerkin: Finite element approximations on a manifold in the configuration space [Abstract]
(Institute of Structural Analysis and Antiseismic Research, School of Civil Engineering, National Technical University of Athens (NTUA), 2016)
An extension of the Ritz-Galerkin method, based on finding approximations on a finite-dimensional manifold of functions (i.e., not a linear subspace) in the infinite-dimensional exact configuration space, will be presented. This new approach is particularly efficient in computing geometrically exact solutions for problems involving large rotations.

Coupling atomistic models with continuous finite beam elements [Abstract]
(Institute of Structural Analysis and Antiseismic Research, School of Civil Engineering, National Technical University of Athens (NTUA), 2016)
Concurrent simulations of atomistic (discrete) and continuum models are one key to perform static calculations of large atomistic structures. Occurring ghost forces at the interfaces between discrete (atomistic) and continuous regions are a major challenge for the definition of such interfaces. The so called virtual projection method [1] is a class of force-based a/c schemes which reduce (or even avoid) ghost forces. This class of coupling schemes is able to deal with atomistic models consisting of bonded, multi-body ...

Influence Of The Fiber-Matrix-Interaction On The Fracture Behavior Of Regenerated Cellulose Fiber Reinforced Polypropylene
(Society of Plastics Engineers, 2017)
This investigation focuses on the fiber-matrix-interaction of man-made cellulose fibers (RCF) in a PP matrix with an additional MAPP content using an energetic evaluation of the single fiber pull-out test (SFPT). Furthermore glass fibers were characterized for reference purposes. With the SFPT the interfacial shear strength (IFFS) and the critical fiber length (lc) as well as the consumed energy of a fiber pull-out and a fiber rupture were determined. In a following step the resulting values of lc were related to the ...

Joining Investigations of Polymer-Metal-Hybrids for Permanantly Non-Leaking Applications
(Society of Plastics Engineers, 2016)
The demand for light-weight construction and economic efficiency has led to the development of light-weight construction strategies, i.e., multi-material design, in many areas of industry. Here, the property profiles of the composite partners are utilized synergetically. Plastic-metal hybrid composites possess a large amount of potential in this regard owing to the weight reduction that can be achieved in the composite and the simultaneous enhancement of the mechanical properties.
Hybrid components have already ...
