  • Patent number: 7330804
    Abstract: A constrained non-linear approximator for empirical process control is disclosed. The approximator constrains the behavior of the derivative of a subject empirical model without adversely affecting the ability of the model to represent generic non-linear relationships. There are three stages to developing the constrained non-linear approximator. The first stage is the specification of the general shape of the gain trajectory or base non-linear function which is specified graphically, algebraically or generically and is used as the basis for transfer functions used in the second stage. The second stage of the invention is the interconnection of the transfer functions to allow non-linear approximation. The final stage of the invention is the constrained optimization of the model coefficients such that the general shape of the input/output mappings (and their corresponding derivatives) are conserved.

  • Publication number: 20080033705
    Abstract: Data from kinetic surface plasmon resonance measurements are fitted to time-profile curves. Time profile curves with sub-threshold curvature are flagged as being insufficient to provide reliable determinations of kinetic parameters and binding affinity. The remaining curves are used to calculate the kinetic parameters and binding affinity, obviating the need for multiple runs for these purposes. The resulting increase in throughput enables drug discovery methods in which kinetic measurements are performed earlier in the screening processes, e.g., so that all or most primary-screen hits can be subjected to data-rich kinetic measurements for screening purposes.

  • Patent number: 7149675
    Abstract: A method for automatically mapping state elements between a first circuit and a second circuit is described. The method proceeds by comparing, in a structural phase, structural features of state elements in the first circuit to structural features of state elements in the second circuit for equivalence. Mappings between state elements of the first circuit and the second circuit are determined based on the comparison of structural features. “Don't care” input conditions are then accounted for prior to determination of functional features. During an inversion detection phase, the polarity of the mappings found in the prior structural phase are determined. A functional phase follows in which the functionality of state elements in the first circuit are compared to the functionality of state elements in the second circuit for equivalence using a three-valued random simulation and further mappings are determined based upon the functional comparison.

  • Patent number: 7054756
    Abstract: In a bacteriological examination system, an expected range of drug sensitivity is calculated from the results of statistics of data acquired at past drug sensitivity tests. Testing panels accommodating drugs of different densities (ex. increasing by increments) covers the calculated expected range are selected for testing. An average-per-sample value of drug sensitivities of bacteria that reside in a hospital and an average-per-sample value of drug sensitivities of bacteria that reside in a limited region are preserved separately in a results-of-test database. A difference between statistical values of drug sensitivities of one bacterial species in a bacterial classification group residing in a hospital to an object drug and statistical values of drug sensitivities of the bacterial species residing in a limited region is calculated. The difference then is divided by the average-per-same value in the limited region.

  • Patent number: 7043415
    Abstract: A method for interactively constructing pharmacological computational models is disclosed. A graphical user interface is presented through which a user may place and connect objects representing pharmacokinetic and pharmacodynamic elements. As the objects are placed and connected, they are converted into an internal format representing the statements of the corresponding computational model. These statements are actively presented to the user in a summarized form, as the computational model is constructed, to enable immediate verification of the model. This summarized form may be a surface syntax showing key equations that make up the model, or they may be graphs of behavior of one or more user-selected variables.

  • Patent number: 7024342
    Abstract: A numerical procedure for simulating the behavior of incompressible, viscous fluid in a casting/molding process. The method is based on classical fluid dynamic equations and uses control volume-finite element and numerical techniques to solve the momentum and energy equations to obtain solution for the variable parameters. The method incorporates five additional modules which simulate fluid flow in the shot sleeve, heat transfer between the die and the heat transfer fluid, die cooling by lubricant, formation of mend line. These additional simulation modules produce realistic boundary conditions, and replace many of the assumptions that would have to be made, to solve the governing equations. These added improvements ensure a faster convergence of the numerical solution and a more realistic simulation of the die casting process.

  • Patent number: 6983233
    Abstract: Methods and apparatus, including computer program apparatus, implementing techniques for designing sets of combinatorial experiments. A set of experimental parameters, sampling patterns, and constraints defines a set of experiments that is limited to a volume of a hyperspace defined by the set of experimental parameters. Parameters can be grouped by type such that grouped parameters are constrained to perform a common role in the set of experiments. The practicability of the experiment design can be estimated based on the number of experiments in the set of experiments. The experiment design can be used to prepare one or more combinatorial libraries.

  • Patent number: 6973389
    Abstract: A method of optimizing parameter values in a process for producing a product, which process is essentially controlled by a set of parameters affecting a set of properties characterizing the product. The method uses an analytic hierarchy process (AHP) to associate a weight with each property according to its relative importance to obtain desired product characteristics. The method also uses parameter data and measured property data from a required number of experimental runs of the process, from which data property behavior relations between each property and the parameters are statistically established, which relations give estimated property values. Using the property weights, a process goal function is established, which is expressed in terms of weighted deviations between the estimated property values and the corresponding goal values for the properties. Finally, the process goal function is minimized in order to generate a set of optimal parameter values for the process.

  • Patent number: 6943684
    Abstract: A surveillance system and method for identifying chemical, biological or nuclear attacks or hazards occurring within a large area which combines data derived from a modeling and simulation operation with a surveillance data input. The modeling and simulation operation involves continuous periodic runs of multiple scenarios for various biological, chemical and nuclear agents in various concentrations for a given location. Using real time weather data for each location, a model is made in a database of the effect various concentrations of agents would have at that location and this simulated model is processed. The surveillance data input monitors actual human signs and symptoms for the modeled area. This data with real time weather data is compared with the results of modeling and simulation data for the area to determine if a pattern matching that for any modeled agent is present.

  • Patent number: 6937257
    Abstract: A method for maintaining consistent unit relationships during graphical pharmacological computational model construction is disclosed. A graphical user interface is presented through which a user may place and connect objects representing pharmacokinetic and pharmacodynamic elements. The user may specify units definitions for variables and constants using unit expressions. As the objects are converted into an internal format representing the statements of the corresponding computational model, the unit expressions are included in this internal format as multidimensional data type information. This multidimensional data type information is regularly and automatically propagated for each statement in the internal format to identify inconsistent units. When such inconsistent units are identified, a warning message is generated to notify the user, substantially immediately after the inconsistent units are created.

  • Patent number: 6871169
    Abstract: A novel multivariate model for analysis of absorbance spectra allows for each wavelength or spectral region to be modeled with just enough factors to fully model the analytical signal without the incorporation of noise by using excess factors. Each wavelength or spectral region is modeled utilizing its own number of factors independently of other wavelengths or spectral regions. An iterative combinative PCR algorithm allows a different number of factors to be applied to different wavelengths. In an exemplary embodiment, a three-factor model is applied over a given spectral region. The residual of the three-factor model is calculated and used as the input for an additional five-factor model. Prior to the additional five factors being applied, some of the wavelengths are removed. This leads to a three-factor model over the first region and an eight-factor model over the second region.
