Keep Your Options Open : An Information-Based Driving Principle for Sensorimotor Systems
(2008)
The central resource processed by the sensorimotor system of an organism is information. We propose an information-based quantity that allows one to characterize the efficiency of the perception-action loop of an abstract ...
Automatic Analysis of Computation in BioChemical Reactions
(2008)
We propose a modeling and analysis method for biochemical reactions based on finite state automata. This is a completely different approach compared to traditional modeling of reactions by differential equations. Our method ...
Teaching robot companions : The role of scaffolding and event structuring
(2008)
For robots to be more capable interaction partners they will necessarily need to adapt to the needs and requirements of their human companions. One way that the human could aid this adaptation may be by teaching the robot ...
Naturally occurring gestures in a human-robot interaction teaching scenario
(2008)
This paper describes our general framework for the investigation of how human gestures can be used to facilitate the interaction and communication between humans and robots. Two studies were carried out to reveal which ...
Discriminating coding, non-coding and regulatory regions using rescaled range and detrended fluctuation analysis
(2008-01)
In this paper we analyse the efficiency of two methods, rescaled range analysis and detrended fluctuation analysis, in distinguishing between coding DNA, regulatory DNA and non-coding non-regulatory DNA of Drosophila ...
Communication and complexity in a GRN-based multicellular system for graph colouring
(2008)
Artificial Genetic Regulatory Networks (GRNs) are interesting control models through their simplicity and versatility. They can be easily implemented, evolved and modified, and their similarity to their biological counterparts ...
Genetic regulatory network models of biological clocks : evolutionary history matters
(2008)
We study the evolvability and dynamics of artificial genetic regulatory networks (GRNs), as active control systems, realizing simple models of biological clocks that have evolved to respond to periodic environmental stimuli ...
An assertion concerning functionally complete algebras and NP-completeness
(2008)
In a paper published in J. ACM in 1990, Tobias Nipkow asserted that the problem of deciding whether or not an equation over a nontrivial functionally complete algebra has a solution is NP-complete. However, close examination ...
Computational memory architectures for autobiographic agents interacting in a complex virtual environment : a working model
(2008)
In this paper, we discuss the concept of autobiographic agent and how memory may extend an agent's temporal horizon and increase its adaptability. These concepts are applied to an implementation of a scenario where agents ...
Human to robot demonstrations of routine home tasks: exploring the role of the robot's feedback
(2008)
In this paper, we explore some conceptual issues, relevant for the design of robotic systems aimed at interacting with humans in domestic environments. More specifically, we study the role of the robot's feedback (positive ...
