However, most of these approaches are not suitable for handling the wide variety of ATM services and diversity of their combinations. Building an efficient network controller which can control the network traffic is a difficult task. The advantage of using neural nets in ATM is that the QoS can be accurately estimated without detailed user action models or knowledge about the switching system architecture. The disadvantage is that it will take longer time to train with ATM network changes. In this paper, we use genetic algorithms in neural network weights training for ATM call admission control and usage parameter control. The simulation results have shown not only a guarantee for the QoS of all the services, but also a saving of the system bandwidth and an improvement of the throughput.","PeriodicalId":289764,"journal":{"name":"Proceedings.

Static and kinetic friction are major obstacles in the control of a mechanical hand. The paper presents a fuzzy based controller which has the ability to automatically regenerate the member set during the translation of an arbitrary joint in a robotic hand. This control system has been implemented on an IBM compatible computer using a custom designed acquisition/conversion interface and a mechanical hand assembly. A series of experiments have been conducted which verify that the method of fuzzy blocks was successful for controlling joint position. The simulation results include bath fine movements, needed for dexterity, and gross movements which can be used for grasping. This system provides excellent results and it is extremely cost effective.","PeriodicalId":289764,"journal":{"name":"Proceedings. IEEE International Joint Symposia on Intelligence and Systems (Cat.

The power of the sinusoids is usually split between the two nearby frequency bins when the location of the sinusoid does not coincide exactly with the location of the frequency bins. Using these power values the exact sinusoid frequency and hence the pitch frequency can be determined. Two solutions, one exact and one approximate are derived. The results obtained from both the algorithms provide very good approximation to the exact frequency location of the sinusoids.","PeriodicalId":289764,"journal":{"name":"Proceedings.

We extend a previous control approach, virtual model control (VMC) (Pratt et al., 1997), to create adaptive virtual model control (AVMC). The adaptation compensates for external disturbances and unmodelled dynamics, enhancing robustness in the control of height, pitch, and forward speed. The state machine used to modulate the virtual model components and to select the appropriate virtual to physical transformations (as in traditional VMC) is also used to inform the adaptation about the robot's changing configuration. The design procedure for AVMC is described in this paper and simulation results are presented for a planar walking biped.","PeriodicalId":289764,"journal":{"name":"Proceedings.

However, unknown to Adleman and this field, two ciliated protozoans of the genus Oxytricha had solved an even harder problem using DNA several million years earlier. In general, the processes of gene unscrambling and editing present two of nature's ingenious solutions to the problem of gene assembly.","PeriodicalId":289764,"journal":{"name":"Proceedings.

In the method, the feature to be extracted is defined as a pair of a delegate structure and a cluster region. The delegate structure is generated by estimating the center of structural balance among proteins in one cluster from the viewpoint of transformation costs. The cluster region shows how far the cluster spread. The validity of the proposed feature extraction method is confirmed through the application to the convenient classification of unclassified proteins.","PeriodicalId":289764,"journal":{"name":"Proceedings.

The project discussed focuses on automating the procedures relating to the Shuttle's Remote Manipulator System and is a pathfinder project for the automation of other Shuttle operations. The RMS Assistant system is designed to track the expected steps of the crew as they carry out RMS operations, detecting malfunctions in the RMS system from failures or improper configurations as well as improper or incomplete procedures by the crew. In this regard, it is a \"flight controller in a box\". Moving the flight controller functions on-orbit is part of a larger program of downsizing general Space Shuttle operations. The 3T architecture was designed for intelligent autonomous robots, but has an added capability that allows for variable autonomy to include full teleoperation. In that mode, the software acts as a monitoring system, and thus provides an \"assistant\" framework now and accommodates more autonomous operations in the future.","PeriodicalId":289764,"journal":{"name":"Proceedings.

Control: an emergent biological property 控制:一种突现的生物特性

As yet, no one been able to train a jellyfish to any associations. The jellyfish however, can attack prey, feed, swim, reproduce and perform all other functions necessary for life. Since we know that slightly more advanced creatures can form associations, a reasonable speculation would be that the neural circuitry involved in forming associative memories evolved from the neural circuitry involved in control tasks. In this paper this speculation is further explored and its consequences discussed. Our explorations have given further credence to this speculation. We have been experimenting with simple biologically plausible artificial neural networks, or ANNs, which consist of two input neurons and one output neuron and are called three-neuron controllers (TNC). The biological plausibility of our ANNs arises from the fact that the activity level of the receiving neuron is determined by integrating over time the transmissions of the two input neurons. The transmission rate of the two input neurons is determined by their activity levels, which we have assumed constant over each integration. The integrating of the two inputs achieves a form of control which resembles that obtained by a fuzzy logic controller.","PeriodicalId":289764,"journal":{"name":"Proceedings.
