A switching network that utilizes at least three degrees of freedom, time, wavelength and space. In one embodiment that involves point-to-point switching, each space channel between an input and an output is assigned a time slot and wavelength coordinate characteristic of the output and the input transmitter and output receiver are tuned to the appropriate time and wavelength coordinates and selective switching is used to complete the space channel between the input and output. In another embodi...

A technique to implement an integrated multidimensional sorter (306) is to store data such that it may be retrieved in a sorted fashion. Entries are stored (407) into a memory according to time stamp value, and the time stamp value is divided (412) into multiple portions. The memory is organized as a pointer memory (505, 508, 513, and 520). An integrated multidimensional sorter may be implemented using integrated circuit technology using one or more integrated circuits (306). These integrated ci...

The morphology of multidimensional oligomers is combined with the inclusion of charge carrier linkages within the oligomer arms to produce oligomers that are useful for preparing conductive or semiconductive composites, if suitably doped. The Schiff base linkages are prepared by the condensation of aldehydes and amines. The oligomers can be blended, and either the oligomers or their blends can be prepregged.

An automatic peak selection method for multidimensional data that selects peaks from very noisy data such as two-dimensional liquid chromatography-mass spectrometry (LC-MS) data is described. Such data are characterized by non-normally distributed noise that varies in different dimensions. The method computes local noise thresholds for each one-dimensional component of the data. Each point has a local noise threshold applied to it for each dimension of the data set, and a point is selected as a ...

A multidimensional ring network includes a plurality of network processing devices that are connected together with a plurality of individual ring networks. Packets are sent between any two network processing devices on the same ring network. Intermediate network processing devices, located on that same ring, between the sending and receiving network processing devices, do not add additional hops to the packet transfer. The intermediate processing devices, between the sending and receiving devic...

Method and system for determining the effects of variation of N statistically distributed variables (N.gtoreq.1) in a fabrication process for semiconductor and other electronic devices by constructing and using an N-variable model function G(x.sub.1, . . . ,x.sub.N) to model the process. A sequence of orthogonal polynomials is associated with each probability density function P.sub.i (x.sub.i) for each variable x.sub.i. These orthogonal polynomials, and products of these polynomials, are used to...

A family of multi-dimensional convolutionally coded modulation systems achieves enlarged minimum distance between possible sequences of signal points, reduced number of error events with the minimum distance, acceptable peak-to-average power ratio, reduced number of signal points in each constituent two-dimensional constellation, immunity to rapid carrier phase changes, and reduced complexity, resulting in a reduced error probability when maximum likelihood decoding is used. These advantages are...

A data storage system for multidimensional parity protection includes a housing for containing a plurality of conventional disk drives for storing data wherein each of the conventional data disk drives is symmetrically linked to at least three parity disk drives for guarding data stored on the data disk drives. Each of the conventional data disk drives thereby have a three dimensional parity relationship with three parity data disk drives such that a three dimensional, mirrored, orthogonal parit...

A method of and apparatus for graph partitioning involving the use of a plurality of eigenvectors of the Laplacian matrix of the graph of the problem for which load balancing is desired. The invention is particularly useful for optimizing parallel computer processing of a problem and for minimizing total pathway lengths of integrated circuits in the design stage.

The yield of fully substituted, multidimensional aromatic hubs in the condensation of hydroxyl and acid halide functionalities is improved by adding a thallium catalyst, such as thallium ethoxide (T1-OC.sub.2 H.sub.5), in the solvent.
