A Forced Roll Mechanism was designed and built at the Hydromechanics Laboratory at the United States Naval Academy. The FRM was designed as a dynamometer that forces a planing hull model in roll and measures the resulting roll moment as well as the heave and sway forces. The model is fully restrained in all six degrees of freedom. The dynamometer can be configured to either oscillate the model ...

This paper presents a unified robust motion control scheme for robot manipulators in state space. The controller design task is carried out based on feedforward control sketch in state space framework with no need to the Computed Torque Control (CTC) which is usually used in many other control approaches. In the proposed approach, the load torque and some other uncertainties in the linear model...

This paper deals with the problem of planning safe trajectories for a manipulator robot moving in an environment including both static obstacles and objects (other robots, conveyors ...) whose positions may change during the interval of time separating two planning steps. In order to solve this problem for a general manipulator having six degrees of freedom, we have developed and implemented a ...

According to the small-world concept, the entire world is connected through short chains of acquaintances. In popular imagination this is captured in the phrase six degrees of separation, implying that any two individuals are, at most, six handshakes away. Social network analysis is the understanding of concepts and information on relationships among interacting units in an ecological system. I...

In this paper we present a hybrid recognition system that analyzes its environment by active vision techniques. Therefore, the system is gathering information about an object in the scene by taking multiple views. It is designed as a hybrid system that brings together the advantages of neural networks and knowledge based strategies. While the analysis of a single view is done by artificial neur...

Six Degrees of Separation is the idea that any two random people in the world are at most six degrees apart in terms of social connections from each other. We hypothesize that there exists a similar property for proper nouns. With abundant information resources on the Internet such as Wikipedia, we should be capable of studying the connections between proper nouns. Nevertheless, the problem is ...
