In this paper, we demonstrate by means of two examples how to work with probability propagation nets (PPNs). The fiirst, which comes from the book by Peng and Reggia [1], is a small example of medical diagnosis. The second one comes from [2]. It is an example of operational risk and is to show how the evidence flow in PPNs gives hints to reduce high losses. In terms of Bayesian networks, both examples contain cycles which are resolved by the conditioning technique [3].
Avoidance of routing loops
(2009)
We introduce a new routing algorithm which can detect routing loops by evaluating routing updates more thoroughly. Our new algorithm is called Routing with Metric based Topology Investigation (RMTI), which is based on the simple Routing Information Protocol (RIP) and is compatible to all RIP versions. In case of a link failure, a network can reorganize itself if there are redundant links available. Redundant links are only available in a network system like the internet if the topology contains loops. Therefore, it is necessary to recognize and to prevent routing loops. A routing loop can be seen as a circular trace of a routing update information which returns to the same router, either directly from the neighbor router or via a loop topology. Routing loops could consume a large amount of network bandwidth and could impact the endtoend performance of the network. Our RMTI approach is capable to improve the efficiency of Distance Vector Routing.
In this paper we describe a network for distributing personalized information within a pervasive university. We discuss the system architecture of our Bluetooth-based CampusNews-system, both, from the administrator and the user viewpoint. We furthermore present first statistical data about the usage of the partial installation at the Koblenz campus together with an outlook to future work.
In this paper we describe a network for distributing personalized Information in a metropolitan area. We discuss the system architecture of our Bluetooth-based information system as well as the reasoning process that fits users" needs with potential messages. We furthermore present our findings on parallelizing Bluetooth connection setup and performance.
CAMPUS NEWS - artificial intelligence methods combined for an intelligent information network
(2008)
In this paper we describe a network for distributing personalised information with the usage of artificial intelligence methods. Reception of this information should be possible with everyday mobile equipment. Intelligent filtering and spam protection aim at integrating this technology into our environment. Information on the system architecture and usage of the installation are also presented.
From September 4 to 11, 1992, a fiirst meeting between Ukrainian and German scientists interested in mathematical and computer modeling of social processes was held at Vorzel' near Kiev. The meeting had been planned for nearly three years by Igor V. Chernenko and Mikhail V. Kuz'min, then members of the research group on mathematical modeling in sociology at the Institute of Sociology of the Academy of Science of the Ukrainian Republic, and had to be postponed twice due to the political development in the former Soviet Union, but thanks to the organizers' perseverance (and in spite of a strike of the airport personell at Kiev Borispol Airport on the eve of the conference) the conference could at last be realized.rnThe main purpose of the conference was to discuss a synergetic interpretation of large-scale destructive social processes as catastrophic phenomena in self-organized systems.
The aim of this paper is to identify and understand the risks and issues companies are experiencing from the business use of social media and to develop a framework for describing and categorising those social media risks. The goal is to contribute to the evolving theorisation of social media risk and to provide a foundation for the further development of social media risk management strategies and processes. The study findings identify thirty risk types organised into five categories (technical, human, content, compliance and reputational). A risk-chain is used to illustrate the complex interrelated, multi-stakeholder nature of these risks and directions for future work are identified.
Ontologies play an important role in knowledge representation for sharing information and collaboratively developing knowledge bases. They are changed, adapted and reused in different applications and domains resulting in multiple versions of an ontology. The comparison of different versions and the analysis of changes at a higher level of abstraction may be insightful to understand the changes that were applied to an ontology. While there is existing work on detecting (syntactical) differences and changes in ontologies, there is still a need in analyzing ontology changes at a higher level of abstraction like ontology evolution or refactoring pattern. In our approach we start from a classification of model refactoring patterns found in software engineering for identifying such refactoring patterns in OWL ontologies using DL reasoning to recognize these patterns.
Autonome Systeme, wie Roboter, sind bereits Teil unseres täglichen Lebens. Eine Sache, in der Menschen diesen Maschinen überlegen sind, ist die Fähigkeit, auf sein Gegenüber angemessen zu reagieren. Dies besteht nicht nur aus der Fähigkeit zu hören, was eine Person sagt, sondern auch daraus, ihre Mimik zu erkennen und zu interpretieren.
In dieser Bachelorarbeit wird ein System entwickelt, welches automatisch Gesichtsausdrücke erkennt und einer Emotion zuordnet. Das System arbeitet mit statischen Bildern und benutzt merkmalsbasierte Methoden zur Beschreibung von Gesichtsdaten. In dieser Arbeit werden gebräuchliche Schritte analysiert und aktuelle Methoden vorgestellt. Das beschriebene System basiert auf 2D-Merkmalen. Diese Merkmale werden im Gesicht detektiert. Ein neutraler Gesichtsausdruck wird nicht als Referenzbild benötigt. Das System extrahiert zwei Arten von Gesichtsparametern. Zum einen sind es Distanzen, die zwischen den Merkmalspunkten liegen. Zum anderen sind es Winkel, die zwischen den Linien liegen, die die Merkmalspunkte verbinden. Beide Arten von Parametern werden implementiert und getestet. Der Parametertyp, der die besten Ergebnisse liefert, wird schließlich in dem System benutzt. Eine Support Vector Machine (SVM) mit mehreren Klassen klassifiziert die Parameter. Das Ergebnis sind Kennzeichen von Action Units des Facial Action Coding Systems (FACS). Diese Kennzeichen werden einer Gesichtsemotion zugeordnet.
Diese Arbeit befasst sich mit den sechs Basisgesichtsausdrücken (glücklich, überrascht, traurig, ängstlich, wütend und angeekelt) plus dem neutralen Gesichtsausdruck. Das vorgestellte System wird in C++ implementiert und an das Robot Operating System (ROS) angebunden.
Cloud Computing is a topic that has gained momentum in the last years. Current studies show that an increasing number of companies is evaluating the promised advantages and considering making use of cloud services. In this paper we investigate the phenomenon of cloud computing and its importance for the operation of ERP systems. We argue that the phenomenon of cloud computing could lead to a decisive change in the way business software is deployed in companies. Our reference framework contains three levels (IaaS, PaaS, SaaS) and clarifies the meaning of public, private and hybrid clouds. The three levels of cloud computing and their impact on ERP systems operation are discussed. From the literature we identify areas for future research and propose a research agenda.
