In recent years the work on vector field visualization has been concentrated on LIC-based methods. In this paper we propose an alternative solution for the visualization of unsteady flow fields. Our approach is based on the computation of temporal series of correlated images. While other methods are based on pathlines and try to correlate successive images at the pixel level, our approach consi...

Feed-forward neural networks are commonly used for pattern classification. The classification accuracy of feed-forward neural networks depends on the configuration selected and the training process. Once the architecture of the network is decided, training algorithms, usually gradient descent techniques, are used to determine the connection weights of the feed-forward neural network. However, g...

A method for shortening of the settling time in all digital phase-locked loops is proposed. The method utilizes self monitoring to obtain the parameters necessary for feed-forward compensation. Analysis shows that by employing this technique both fast settling and good stability can be achieved simultaneously. Matlab and Verilog-AMS simulation shows that typical settling speed can be reduced to...

The problem of channel coding with feedback has been extensively studied over the last 50 years. Using an ideal feedback link, the encoder knows all previously received channel outputs. Recently the duality between channel coding and rate distortion has been established in [15] and [3], leading to the problem of source coding with feed-forward. In this project we first study the general formula...

A popular approach to training feed-forward nets is to treat the problem of adaptation as a function approximation and to use curve fitting techniques. We discuss here the problems which the use of pure curve fitting techniques entail for the generalization capability and robustness of the net. These problems are in general inherently associated with the use of pure supervised learning techniqu...

The wind speed has a huge impact on the dynamic response of wind turbine. Because of this, many control algorithms use a measure of the wind speed to increase performance, e.g. by gain scheduling and feed forward. Unfortunately, no accurate measurement of the effective wind speed is online available from direct measurements, which means that it must be estimated in order to make such control me...

system. There are, no doubt, distinctions to be made within this level of knowledge systems, and significant, often radical, conceptual change takes place as one formal system displaces another in the domain, as Carey (1991) and Chi (1992) have both discussed. These change levels both feed forward and then feed backward, as Figure 11.1 indicates. 348 Language in Cognitive Development The Mediat...
