Abstract: A system and method provide access by a web application running on a host computing device in communication with a remote server to a native binary DLL. A browser extension to the web application and a native messaging application communicate with the browser extension via standard input/output. A long-running computational process on the host computing device configured as a wrapper for the binary DLL is executable by the host computing device. The native messaging application and the long-running computational process communicate with one another via a named pipe, and the long-running computational process duration is independent of the native messaging application duration.

Abstract: A pseudo micro computed tomography (CT-like) image of a porous material is produced. A chemistry-based 3D structure of a porous material system is generated, and a Connolly surface for the 3D structure is determined. A volume field of the 3D chemistry-based structure is calculated from the Connolly surface. A text-format file layer having layer by layer information of the volume field is generated. The text-format layer file is converted into a CT-like binary image file in the RAW format. The binary image file is converted to a black and white or grayscale images. A pore size analysis (PSA) simulation is performed to produce grain images and pore images for the porous material system.

Abstract: Techniques for simulating fluid flow using a lattice Boltzmann (LB) approach for solving scalar transport equations and solving for total energy are described. In addition to the lattice Boltzmann functions for fluid flow the techniques include modifying a set of state vectors of the particles by adding specific total energy to states of particles that will be advected and subtracting the specific total energy from states of particles that will not be advected over a time interval and performing advection of the particles according to the modified set of states.

Abstract: Embodiments assess vehicle noise. One such embodiment defines a computer-based model of a vehicle and automatically determines aerodynamic performance and propulsion performance of the vehicle based on the defined computer-based model. Responsively, a flight-dynamics simulation of the vehicle is performed using the determined aerodynamic performance and propulsion performance. Performing the flight-dynamics simulation produces flight status data. The flight status data is automatically down-sampled to generate a reduced dataset. A high-fidelity flow simulation of the vehicle is performed using the reduced dataset. Performing the high-fidelity flow simulation determines in-flight aerodynamic and aeroacoustic performance of the vehicle. In turn, based on the determined in-flight aerodynamic and aeroacoustic performance, noise physical characteristics of the vehicle are determined and an indication of the determined noise physical characteristics is stored in computer memory.

Abstract: Embodiments simulate a manufacturing resource including a cable by creating a polyline model of the cable that includes a collection of points. For each point, there is an associated point mass and zero mass sphere, and an assigned elasticity and torsional stiffness between the point and adjacent points. Position and orientation of a start point and an end point of the points is defined based upon position in three dimensional (3D) space of a manufacturing resource. In turn, a simulation of the cable for a time step is performed by computing forces on each point using: (i) the associated point mass, (ii) the associated zero mass sphere, (iii) the assigned elasticity and torsional stiffness between the point and adjacent points, and (iv) the defined position and orientation of the start point and end point. Performing the simulation determines position in 3D space of each point based on the computed forces.

Abstract: Embodiments assess ergonomic risk in environments, such as factories and workstations. One such embodiment begins by receiving process planning data for an operator performing a task. In turn, the received process planning data is used to generate a posture for the operator to perform the task in a certain real-world environment. The generated posture is processed using a hierarchical decision tree to determine ergonomic risk of the posture in the certain real-world environment. Output includes an indication of the determined ergonomic risk.

Abstract: Embodiments determine manikin posture for simulations of real-world environments. An embodiment automatically generates a phrase by performing a hierarchical analysis using data regarding the real-world environment. According to an embodiment, the generated phrase describes a task, to be simulated, performed by a manikin in an environment. In turn, one or more posture engine inputs are determined based on the generated phrase. The posture for the manikin in a simulation of the manikin performing the task in the environment is then automatically determined based on the determined one or more posture engine inputs.

Abstract: An automated system and method to investigate degradation of cathode materials in batteries via atomistic simulations, and in particular by simulating the creation of atomistic defects in the cathode material, which occurs during charge cycling. A systematic procedure relates the degradation of battery performance metrics to underlying structural changes due to atomic rearrangements within the material, for example through density functional theory simulations. The performance metrics modeled with this approach include the Open Cell Voltage (OCV) as well as the discharge capacity curve.

Abstract: In accordance with one embodiment of the invention, features of biological sequences are represented in a fingerprint that includes a bitset, and may also include counts, strings or continuous values, for the features. The fingerprint can be used with machine learning and statistical methods. This is especially advantageous for, though not limited to, drug discovery processes. The method permits Structure-Activity Relationship (SAR) and Quantitative Structure-Activity Relationship (QSAR) studies to be performed with biological sequences.
