摘要:
A hairdressing preparation comprising at least one polyether compound resulting from the addition polymerization of 20 to 90 moles of propylene oxide to 1 mole of a polyhydric alcohol to form a main chain, and the subsequent addition polymerization of 1 to 10 moles of ethylene oxide to the resulting main chain, the amount of ethylene oxide being further within the range of 1 to 10% by weight based on the total amount of propylene oxide and ethylene oxide. The hairdressing preparation has good dressability, good feeling in use, good washability from the hair and wearing apparel and extremely low eye irritation and toxicity.

摘要:
A system for building an artificial neural network is provided which precisely defines the network's structure of artificial neurons, and non-iteratively determines the synapse-weights and hard limiter threshold of each artificial neuron of the network. The system includes a computer for analyzing input data, which represents patterns of different classes of signals, to generate one or more data points in two or three dimensions representative of the signals in each of the different classes. A distribution of the data points is visualized on a map on an output device coupled to the computer. The data points are clustered on the map into clusters in accordance with the classes associated with the data points, and the map is then partitioned into regions by defining linear boundaries between clusters. The artificial neural network is configured in accordance with the data points, clusters, boundaries, and regions, such that each boundary represents a different artificial neuron of the artificial neural network, and the geometric relationship of the regions on the map to the classes defines the logic connectivity of the artificial neurons. The synaptic weights and threshold of each artificial neuron in the network are graphically determined based on the data points of the map.
