A seismic modeling system may include a seismic model data storage device, and a processor cooperating with the seismic model data storage device to determine a first 3D boundary around a suspect region within a first seismic model spatial domain data set for a geological formation at a first time, and determine a second 3D boundary around the suspect region within a second seismic model spatial domain data set for the geological formation at a second time and after movement of the suspect region. The processor may also compare the second 3D boundary to the first 3D boundary to determine an overlapping portion where the first and second 3D boundary regions overlap, and at least one non-overlapping portion where the first and second 3D boundaries do not overlap, and inpaint the overlapping portion based upon the at least one non-overlapping portion.

A distribution analysis device analyzes a distribution of a field having a property satisfying the Laplace equation, and includes: an obtainment unit (11) that obtains measurement data indicating the distribution of the field measured through a sensor sensing area, the sensor sensing area being an area that moves in a measurement area where the distribution of the field is measured and being an area in which the field is sensed as an aggregate; and a calculation unit (12) that calculates analysis data indicating the distribution of the field with a higher resolution than the measurement data, using an arithmetic expression that is obtained by deriving a solution of the Laplace equation using a boundary condition that an integral of the solution of the Laplace equation in a finite interval corresponding to a size of the sensor sensing area matches the measurement data.

A method and computer system for identifying genes associated with a phenotype includes obtaining data representing mutations in a cohort of subjects exhibiting a phenotype. An evolutionary action (EA) score is calculated for each mutation using the data obtained. For each gene in the cohort, respective distributions of the calculated EA scores are determined for mutations found in the gene. The determined distributions of EA scores are quantitatively compared within the cohort and with random distributions to establish comparison data. Based on the comparison data, distributions of EA scores are identified that are non-random, and linkage of each gene in the cohort to the phenotype is assessed based on the identified non-random distributions to identify genes associated with the phenotype. The phenotype can be a disease, such as cancer, and linkage of each gene in the cohort to the disease can be assessed to identify disease causing genes.

In one embodiment, a model predictive control system for an industrial process includes a processor to execute an optimization module to determine manipulated variables for the process over a control horizon based on simulations performed using an objective function with an optimized process model and to control the process using the manipulated variables, to execute model modules including mathematical representations of a response or parameters of the process. The implementation details of the model modules are hidden from and inaccessible to the optimization module. The processor executes unified access modules (UAM). A first UAM interfaces between a first subset of the model modules and the optimization module and adapts output of the first subset for the optimization module, and a second UAM interfaces between a second subset of the model modules and the first subset and adapts output of the second subset for the first subset.

A continuous dynamical system is converted to a Markov decision process (MDP) with discrete states. A predetermined number of continuous states of the continuous system is selected, wherein each continuous state corresponds to one discrete state of the MDP. Delaunay triangulation is applied to the continuous states to produce a set of triangles, wherein vertices of each triangle represent the continuous states. For each discrete state, a next discrete state y = f ( x, a ) is determined, wherein x represents the continuous state corresponding to the discrete state, a is a control action, and f is a non-linear transition function for the continuous state. A particular triangle containing the next discrete state y is identified, and the next discrete state y is expressed as probabilities of transitioning to the discrete states corresponding to the continuous states x represented by the vertices of the particular triangle.
