In this work an approach for image based 6-DOF pose estimation, with respect to a given 3D point cloud model, is presented. We use 3D annotated training views of the model from which we extract natural 2D features, which can be matched to the query image 2D features. In the next step typically the Perspective-N-Point Problem in combination with the popular RANSAC algorithm on the given 2D-3D po...

In the pair of papers of which this is Part I, the agent-oriented modeling perspective to cope with biological complexity is discussed. Three levels of dynamics are distinguished and related to each other: dynamics of externally observable agent behavior, dynamics of internal agent processes, and dynamics of multi-agent organisations. Basic agent concepts to describe externally observable agent...

A number of modeling perspectives are relevant to the design of intel l igent, adaptive, and collaborative support for humans who work in complex sociotechnical, systems. We first describe the separate s t r a n d s o f normative m o d e l s o f activity and communication and self-organizing m o d e l s o f organizational a d a p t a t i o n t o technology, and then braid them together to arriv...

Was the spread of agropastoralism from the Eurasian founder regions dominated by demic or by cultural diffusion? This study employs a mathematical model of regional sociocultural development that includes different diffusion processes, local innovation and societal adaptation. Simulations hindcast the emergence and expansion of agropastoral life style in 294 regions of Eurasia and North Africa....

We present a successful design approach for social robotics based on a computational cognitive architecture and mental simulation. We discuss an approach to a Theory of Mind known as a “like-me” simulation in which the agent uses its own knowledge and capabilities as a model of another agent to predict that agent’s actions. We present three examples of a “like-me” mental simulation in a social ...

As models are always abstractions of reality, we often need multiple modeling perspectives for analysis. The interplay of such modeling perspectives can take many forms and plays a role both at the design level, and during the operation of information systems. Examples include viewpoint resolution in requirements management, mapping between conceptual and implementation design in databases, and...

There is an urgent need for a reference conceptual framework regarding the understanding of business processes based on the Language-Action Perspective (LAP). Several frameworks have been proposed in the past years, but they appear to differ in several important aspects, and none of them is widely accepted yet. This paper intends to contribute to the establishment of such a framework. It does s...

ÐThe determination of camera position and orientation from known correspondences of 3D reference points and their images is known as pose estimation in computer vision and space resection in photogrammetry. It is wellknown that from three corresponding points there are at most four algebraic solutions. Less appears to be known about the cases of four and five corresponding points. In this paper...

This chapter discusses the stability of the Atlantic thermohaline circulation with special emphasis on the critical thresholds and state transitions found in model experiments. The thermohaline ocean circulation is a major heat transport mechanism which causes the relatively mild climate in the North Atlantic region (including Europe) in the modern times. The formation of North Atlantic Deep Wa...

This paper discusses current versions of WordNet from a data modelling perspective. We show that these versions do not consider basic data model desiderata for their design, like flexibility, extensibility and interoperability. We claim that a data model for WordNet must also consider the inherent network structure of WordNet data. Thus we make the case for an RDF model for WordNet and present ...
