Mensch-Roboter-Kollaboration
(2016)
Eine enge Zusammenarbeit von Mensch und Roboter, die sogenannte Mensch-Roboter-Kollaboration (MRK), könnte eine bisher beispielslose Produktivität entstehen lassen. Bis zur allgemeinen Nutzung der Technologie sind noch zahlreiche Probleme zu lösen, insbesondere die des Arbeits- und Gesundheitsschutzes. Am Institut für Sicherheitsforschung der Hochschule Bonn-Rhein-Sieg wurde in den vergangenen Jahren eine Reihe von Projekten zur Entwicklung von optischen Sensorsystemen für Schutzeinrichtungen durchgeführt. Im Projekt SPAI (Sichere Personendetektion im Arbeitsbereich von Industrierobotern durch ein aktives NIR-Kamerasystem) wurde ein spezielles Kamerasystem für den nahinfraroten (NIR) Spektralbereich entwickelt.

Dieser Artikel stützt sich auf das vom 13.10.2015 bis 12.01.2016 gemeinsam durchgeführten Praxisprojekt von ORBIT und der Hochschule Bonn-Rhein-Sieg. Thema des Projekts waren die Methodenevaluation und Automatisierung von Auswertungsprozessen. Speziell ging es um die Überprüfung der von ORBIT entwickelten Methodik zur Anforderungsanalyse und Standortbestimmung – dem ORBIT-Navigator.
Job-related migration has been fostered across Europe balancing unemployment in one country with demands for employees in others. However, the numbers of early school leavers and university dropouts significantly increased in the hosting countries. We propose a higher measure of cultural sensitivity in education in order to prevent frustration. The Learning Culture Survey investigates learners’ expectations towards and perceptions of education on international level with the aim to make culture in the context of education better understandable. After a brief introduction, we subsume the steps taken during the past seven years and found results. Subsequently, we introduce a method for the determination of conflict potential, which bases on the understanding of culture as the level to which people within a society accept deviations from the usual. We close with demonstrating the usefulness of the data and insights from our Learning Culture Survey in the context of practical scenarios.
In this paper, we introduce the international program erp4students as general example on how to successfully prepare university students for the world of works without having to give up the basic principle in higher education, i.e., to exclusively provide sustainable education. We start with introducing the basic concept and design of the program and provide information regarding the demographic development over the past decade and implemented quality assurance mechanisms. Subsequently, the scope and design of and hitherto achieved insights from the Learning Culture Survey are outlined. On the basis of found results, we finally discuss how erp4students can deal with possible culture-specific issues that latest might emerge when the program gets available for learners in the Asian context.
Effects of Workspace Awareness and Territoriality in Environments with Large, Shared Displays
(2016)
Synchronous cooperative work of multiple collaborators in large, high-resolution display systems comprises such psychological phenomena like workspace awareness and human territoriality. The phenomena and interplay between them can cause a significant impact on human-human and human-environment interaction. In a non-digital environment humans rely on their own physical abilities, utilities, and social protocols to control those phenomena (e.g. close eyes, or use earplugs to reduce workspace awareness; rotate oneself towards collaborators to increase workspace awareness). Digital environments, on the other hand, provide us with a possibility to ease, automate, and unify control processes, thus taking off that burden from users. Yet, we have to understand first, what effects workspace awareness and territoriality have within a collaborative environment. The aim of this doctoral thesis is to investigate effects of workspace awareness and territoriality on users and interaction processes in mixed-focus scenarios of various collaborative settings.
The aim of design science research (DSR) in information systems is the user-centred creation of IT-artifacts with regard to specific social environments. For culture research in the field, which is necessary for a proper localization of IT-artifacts, models and research approaches from social sciences usually are adopted. Descriptive dimension-based culture models most commonly are applied for this purpose, which assume culture being a national phenomenon and tend to reduce it to basic values. Such models are useful for investigations in behavioural culture research because it aims to isolate, describe and explain culture-specific attitudes and characteristics within a selected society. In contrast, with the necessity to deduce concrete decisions for artifact-design, research results from DSR need to go beyond this aim. As hypothesis, this contribution generally questions the applicability of such generic culture dimensions’ models for DSR and focuses on their theoretical foundation, which goes back to Hofstede’s conceptual Onion Model of Culture. The herein applied literature-based analysis confirms the hypothesis. Consequently, an alternative conceptual culture model is being introduced and discussed as theoretical foundation for culture research in DSR.
MOOCs in POM Education
(2016)
Basic demand from enterprises towards academic education: provide students not only methodological/theoretical knowledge, but also prepare them for the future tasks in the world of works! This contradicts academia’s focus on sustainably teaching basic principles. With the extra-curricular international online program erp4students, we successfully managed to bridge this "conflict-of-interest”.
Recent years have seen extensive adoption of domain generation algorithms (DGA) by modern botnets. The main goal is to generate a large number of domain names and then use a small subset for actual C&C communication. This makes DGAs very compelling for botmasters to harden the infrastructure of their botnets and make it resilient to blacklisting and attacks such as takedown efforts. While early DGAs were used as a backup communication mechanism, several new botnets use them as their primary communication method, making it extremely important to study DGAs in detail.
In this paper, we perform a comprehensive measurement study of the DGA landscape by analyzing 43 DGAbased malware families and variants. We also present a taxonomy for DGAs and use it to characterize and compare the properties of the studied families. By reimplementing the algorithms, we pre-compute all possible domains they generate, covering the majority of known and active DGAs. Then, we study the registration status of over 18 million DGA domains and show that corresponding malware families and related campaigns can be reliably identified by pre-computing future DGA domains. We also give insights into botmasters’ strategies regarding domain registration and identify several pitfalls in previous takedown efforts of DGA-based botnets. We will share the dataset for future research and will also provide a web service to check domains for potential DGA identity.
