Sharing of common corridors by gas pipelines and overhead power transmission lines is becoming quite common. Voltages can be induced on gas pipelines from power transmission lines in the sections where they share the corridor. This paper reports on a recently completed study on the interaction between gas pipelines and power transmission lines in a utility common corridor in New South Wales, Au...

In this work the results of a pedestrian counterflow experiment in a corridor of a width of 2 meter are presented. 67 participants were divided into two groups with varying relative and absolute size and walked in opposite direction through a corridor. The video footage taken from the experiment was evaluated for passing times, walking speeds, fluxes and lane-formation including symmetry breaki...

Inspired by the biological perspective of service ecosystems, we propose to define the fitness of services in service networks. In our work, we show how to calculate the service fitness from the provider perspective using locally available information as a reflection of the position of the service in the service network. For that purpose we define a fitness corridor with upper and lower bounds ...

Robust behavioral control programs for a simulated 2d vehicle can be constructed by artificial evolution. Corridor following serves here as an example of a behavior to be obtained through evolution. A controller’s fitness is judged by its ability to steer its vehicle along a collision free path through a simple corridor environment. The controller’s inputs are noisy range sensors and its output...

Honeybees fly down the center of a corridor by equating the speed of optic flow in the lateral field of the two eyes. This flow-equalization strategy has been successfully implemented in mobile robots to guide behavior in cluttered environments. We investigated whether humans use a similar strategy to steer down a corridor and determined the relative contributions of equating the speed of flow ...

This work is about the integration of the skills robot control, landmark recognition, and qualitative reasoning in a single autonomous mobile system. It deals with the transfer of coarse qualitative route descriptions usually given by humans into the domain of mobile robot navigation. An approach is proposed that enables the Bremen Autonomous Wheelchair to follow a route in a building, based on...

Our problem is to control the movement of a robot. By robot we mean a moving autonomous vehicle which moves within a chosen corridor with a constant speed. It should successfully move through the chosen continuous corridor without obstacles. In this contribution we show some approaches to solving this problem. The first approach is based on classical if rules, the second approach is based on fu...

Evolutionary algorithms working on continuous search space can be regarded as general homogeneous Markov chains. The finite space problem of describing the transition matrix turns into the more complicated problem of definining and estimating a transition function. We analyze in this respect the (1+1) evolutionary algorithm on the inclined plane and corridor models. In the first case, the proba...
