Stem cells may be considered complex reactive systems because of their vast number in a living system, their reactive nature, and the influence of local environmental factors (such as the state of neighboring cells, tissue matrix, stem cell physiological processes) on their behavior. In such systems, emergent global behavior arises through the multitude of local interactions among the cell agen...

This paper describes the hardware and software architecture of the Attempto RoboCup-99 team. The different parts of robot, sensor and computer hardware which are used are presented. Then the robot control architecture which realizes a hybrid control, consisting of a reactive behavior based component and a planner component for more complex tasks is introduced. Also the problems we currently are...

This paper addresses the issue of hybridization between reactive and cognitive approaches within a single decision-making architecture for virtual agent in an urban simulation. We use a reactive module in order to manage reactive behaviors and agent autonomy, and a cognitive module for anticipation, learning and complex behaviors management. The purpose of the cognitive module is to increase th...

We provide a computationally tractable model of how organisms can learn to add structures to the world to reduce cognitive complexity. This model is then implemented using two techniques: first using a genetic algorithm, and then using the Q-learning algorithm. The results clearly show that organisms with only reactive behavior can learn to systematically add structures to the world to reduce t...

The main objective of this research is a rigorous investigation of an architectural approach for developing and evolving reactive autonomic (self-managing) systems, and for continuous monitoring of their quality. In this paper, we draw upon our research experience and the experience of other autonomic computing researchers to discuss the main aspects of Autonomic Systems Timed Reactive Model (A...

Abstract This paper presents the nonlinear dynamic analysis of an ideal two-reactant-two product reactive distillation. The impact of disturbance magnitudes and directions on openloop stability of the system is studied. An analysis of the physicochemical phenomena present in reactive distillation processes that, under certain operational conditions, causes special types of nonlinear behavior is...

This paper presents an experimental study using two robots. In the experiment, the robots navigated through an area with or without obstacles and had as their goal to shift places with each other. Four different approaches (random, reactive, planning, anticipation) were used during the experiment and the times to accomplish the task were compared. The results indicate that the ability to antici...

In this work we address the problem of managing the reactive behavior in distributed environments in which data continuously changes over time, where the users may need to explicitly express how the triggers should be (self) modified. To enable this we propose the (ECA) – Evolving and Context-Aware Event-Condition-Action paradigm for specifying triggers that capture the desired reactive behavio...

This paper describes the hardware and software architecture of the Attempto RoboCup-99 team. We first present the design of our heavily modified commercial robotic base, the robot sensors and onboard computer. Then the robot control architecture which realizes a hybrid control, consisting of a reactive behavior based component and a planner component for more complex tasks is introduced. Also t...

We present IGaze, a semi-immersive human-avatar interaction system. Using head tracking and an illusionistic 3D effect we let users interact with a talking avatar in an application interview scenario. The avatar features reactive gaze behavior that adapts to the user position according to exchangeable gaze strategies. In user studies we showed that two gaze strategies successfully convey the in...
