Abstract: Disclosed are methods of modelling a subsurface region. One method comprises defining a plurality of variables for describing said subsurface region, each variable having a corresponding, domain set neighbourhood set, and conflict set. The conflict set comprises conflict variables, which are previously assigned variable which reduces the domain set of its corresponding variable. The method comprises further sequentially performing for each variable: a) selecting an unassigned variable; b) assigning a value to the selected variable from its domain set; c) assessing whether a constraint is satisfied. The selected variable's corresponding conflict set is updated to include any previously assigned variables comprised within the selected variable's corresponding neighbourhood set when said constraint is assessed not to be satisfied at step c). Another method comprises foreseeing dead end variables before they are simulated.

Abstract: Embodiments disclosed herein relate to a model for predicting the release profile of a controlled release device. The implant modeling system and models disclosed herein allow the accurate prediction of a release profile for a controlled release device based on features extracted from micro-resolution imagery. The models combine microstructural features that can be extracted at the XRCT resolution, including pore volume and connectivity, using erosion-dilation image analysis. This strategy allows prediction of release curves of the controlled release device using XRCT despite its resolution limitations.

Abstract: A system designs a thin and relatively flat microwave focusing lens that can produce multiple simultaneous beams, using readily-available isotropic dielectric materials, and having a gradient-index (GRIN) profile. The design optimizes the lens to achieve beam scanning and/or multiple beams over a wide field of regard (FOR) with broad bandwidth and a very short focal length compared with conventional lenses. The lens can be used individually or as an element in a more complex antenna having multiple lenses in various orientations that are independently switched, selected and/or excited simultaneously as elements in a phased array. The antenna terminal incorporates such lens into an array of lenses along with one or more feeds to produce single or multiple beams covering a broad field of regard for such applications as satellite communications on-the-move, cellular, broadband point-point or point-multipoint and other terrestrial or satellite communications systems.

Abstract: A reference curve representing measured stress-strain data obtained in a material test of a specimen is received. FEA model is created to represent the specimen which is associated with numerical material properties defined by a formula having a set of adjustable coefficients. Multiple computed curves are obtained each defined with multiple nodes of computed stress-strain values by conducting a time-marching simulation of the material test using the FEA model with a set of unique coefficients. Respective curve difference measurement parameters are calculated between each computed curve and the reference curve using a similarity measure technique that includes trimming off excess end portion of each computed curve so as to match the reference curve. Optimal values of the adjustable coefficients are determined by estimating a minimum of the curve difference measurement parameters according to an optimization technique.

Operations disclosed herein such as acoustically determining the phase differential accumulated through passive fluid exchange (i.e. diffusion) based on the geometry of the tissue sample, modeling the impact of the diffusion on the TOF, and using a post-processing algorithm to correlate the results to determine the diffusivity constant, are enabled by monitoring the changes in the speed of sound caused by penetration of fixative such as formalin into several tissue samples. A tissue preparation system may be adapted to monitor said diffusion of a tissue sample and determine an optimal processing workflow.
