Abstract: One aspect of the invention is the construction of mixtures of Bayesian networks. Another aspect of the invention is the use of such mixtures of Bayesian networks to perform inferencing. A mixture of Bayesian networks (MBN) consists of plural hypothesis-specific Bayesian networks (HSBNs) having possibly hidden and observed variables. A common external hidden variable is associated with the MBN, but is not included in any of the HSBNs. The number of HSBNs in the MBN corresponds to the number of states of the common external hidden variable, and each HSBN is based upon the hypothesis that the common external hidden variable is in a corresponding one of those states. In one mode of the invention, the MBN having the highest MBN score is selected for use in performing inferencing.

Abstract: A system and method for maintaining data integrity in computer systems which have removable hard drives. The system and method of the present invention ensures that a disk drive which is reinserted into the computer system is the drive used to boot the operating system. When the computer system boots, the system reads the unique drive identification information from the hard drive and stores this identification information in memory for later use. Later, the computer system may be powered down or placed in a suspend state where the hard drive may be removed and a new drive inserted. When the computer system resumes and first requires access to the hard drive, the system and reads the drive identification information from the drive and compares the drive identification obtained from the drive with the drive identification information stored in memory at boot time.

Abstract: There is provided a basic association unit for creating an information processing apparatus capable of performing information processing like information processing that actually occurs in central nerve systems of animals including human beings. The association unit is an unit for repeating input and output signals having m input terminals and n output terminals. When a first input signal which is a rectangular wave signal in the form of a pulse is simultaneously input to input terminals in a quantity less than m, an output signal having the same contents as the first input signal is output from particular output terminals which are associated with the input terminals in advance.

Abstract: A neural network assisted multi-spectral segmentation method and system. According to the invention, three images having different optical bands are acquired for the same micrographic scene of a biological sample. The images are processed and a cellular material map is generated identifying cellular material. The cellular material map is then applied to a neural network. The neural network classifies the cellular material map into nuclear objects and cytoplasmic objects by determining a threshold surface in the 3-dimensional space separating the cytoplasmic and nuclear regions. In another aspect, the neural network comprises a hardware-encoded algorithm in the form of a look-up table.

Abstract: A quantum computer is an array of quantum hits (qubits) together with some hard-ware for manipulating these qubits. Quantum Bayesian (QB) nets are a method of modeling quantum systems graphically in terms of network diagrams. This invention comprises a classical computer running a Computer program that expresses the information contained in a QB net as a sequence of elementary operations (SEO). One can then run these sequences on a quantum computer. We show how to reduce a QB net into a SEO by a two step process. First, express the information contained in the QB net as a sequence of unitary operators. Second, express each of those unitary operators as a SEO. An appendix to this document contains the C++ source code of a computer program called “Qubiter1.0”, which is a preferred embodiment of the invention.

Abstract: A controller for a switched reluctance machine utilizing a feedforward neural network in combination with either a fuzzy logic controller or a proportional-integral controller to provide output control signals (e.g., turn-ON angle, turn-OFF angle and peak current) for controlling the energization of a switched reluctance machine. In an alternate embodiment, a fuzzy logic controller is utilized by itself to control a switched reluctance machine.

Abstract: A method system for optimizing a computer program. In one embodiment, the system identifies depths of blocks of a computer program and identifies the availability of expressions of the computer program. The system then modifies the computer program when he identified availability of the expression and the identified depth of a block indicate that the expression can be moved to the block. The depth of the block may represent the number of dominator blocks of that block. The availability of the expression may represent the depth of a block to which the expression may be moved. In one embodiment, when the identified availability of the expression is less than the identified depth of the block, the expression can be moved to the block.

Abstract: Neural computing techniques are used to optimize route selection in a communication network, such as an ATM network. Output measurements of the network are used to provide optimal routing selection and traffic management. Specifically, link data traffic is monitored in the network to obtain traffic history data. An autoregressive backpropagation neural network is trained using the traffic history data to obtain respective predicted traffic profiles for the links. Particular links are then selected for carrying data based on the predicted traffic profiles. A cost function, limits on network parameters such as link cost and cell rate, and other quality of service factors are also considered in selecting the optimal route.

In one mode of the invention, the MBN having the highest MBN score is selected for use in performing inferencing.

Abstract: An elastic robot body in which a number of actuators are integrated. If the actuators are triggered individually or in groups, they exercise a force on the material of the body, so that the latter changes its shape. Integrated sensors or switches measure the momentary position of the body. An imitation hand, comprising such a body, can move its sections in a human fashion.

Abstract: A projection serves to space the air bearing surface apart from the surface of a recording disk when the recording disk stands still. The contact area can be reduced between a flying head slider and the surface of the recording disk. When the flying head slider inclines downstream around the tip end of the projection in response to a reverse rotation of the recording disk at the beginning of the rotation, the flying head slider allows a rugged surface to contact the surface of the recording disk at the outflow end thereof. The effect of meniscus or adsorption cannot be intensified between the lubricating agent or oil and the air bearing surface, namely, the flying head slider. Accordingly, it is possible to reliably avoid failure in starting the recording disk to rotate. Less torque of the spindle motor allows the recording disk to normally start rotating.

Abstract: A software package manager uses a distribution unit containing components for a software package and a manifest file that describes the distribution unit to manage the installation, execution, and uninstallation of software packages on a computer. Information in the manifest file pertaining to a software package is stored in a code store data structure upon installation of the package. The manifest file also contains information that permits the software package manager to resolve any software dependencies upon installation. The software package manager uses the code store data structure to locate the required components when the software is executed and to remove the components appropriately when the software is uninstalled.

Abstract: A generic way of publishing globally available functionality that can be shared across applications. Utilizing an Installer Registry, an Installer, Descriptors and a Publish Component Table, related components can be retrieved using an qualifier. A request for a listing of related components, which includes a qualifier, is received from an application. The installer retrieves all the related components, matching the qualifier, from the Publish Component Table. The installer then retrieves the features associated with the components and presents the list of components to the application. The application then selects a specific component and the installer then determines the product associated with the selected component by using the feature and component information retrieved from the Publish Component Table. Once the product information is retrieved, the present invention searches the Installer Registry, using the product, feature and component information as a token, and returns a keypath for that token.

Abstract: Computer software for generating flowchart images of a source program. The computer software includes a first program which reads an input program source code as an input and generates a coded output file containing codes that a second program uses to create the shapes of the flowchart or list the copybooks and called programs used in the input program source code being flowcharted. Each line of the source program input is checked character for character for ‘reserved words’ of the source program language. When a ‘reserved word’ is found then a shape code is created. A single program flowchart can be created or by selecting a key word “AUTO”, multiple program flowcharts can be created. The coded output file contains first, second, and third fields. The first field contains a three character shape identifier (the computer software includes 25 predefined shape identifiers). The second field contains a view number and a shape position.
