Abstract: Methods and systems are disclosed to determine a permeability value and a permeability image of a rock. The process can include determining labeling of a 3D segment of a rock. The labeled segments can be determined using, for example, computer vision and machine learning and can be used to determine a grain size of a 3D rock segments. The grain size value can be used to determine a permeability value for the 3D rock segment. The permeability value of the 3D rock segment can be used to determine the heterogeneous permeability of the rock.

Abstract: The passive edge-tone suppression method includes the step of inserting a central insertion tube within a nozzle to disturb jet oscillations in a flow field of an edge-tone feedback loop. The central insertion tube can have a diameter of 200 micrometers and can be inserted within a center of the nozzle. The method also includes the step of extending the central insertion tube through the nozzle and into an alignment with the edge producing the edge tone. Further, the method includes the step of increasing a length of the central insertion tube in relation to a stand-off distance between the nozzle and the edge. The length of the central insertion tube can be increased to a length of about 30 percent of the stand-off distance.

Abstract: A medical device, for example a stent, has a surface which in use contacts body tissue, wherein said surface has on it a biocompatible coating layer comprising a polymer having covalently bound allyl-terminated pendent groups, said pendent groups comprising a moiety selected from -0-CH2—CH?CH2—S—CH2—CH?CH2—S(=0)-CH2—CH?CH2—Se—CH2—CH?CH2 and —Se (=0 J-CH2—CH?CH2. This surface has good biocompatibility and can bind strongly to a metallic surface. The polymer may be made from an electropolymerisable monomer, e.g. a pyrrole.

Abstract: The present invention relates to a screen lock-unlock system for automatically locking and unlocking a screen that is within a fluid channel wherein the screen is rotatable relative to the channel from closed to open. The system includes an actuator comprising a flapper and a trigger, wherein the flapper is rotatably connectable to the back of the screen. The flapper is operably connected to the trigger for moving the trigger. And, the system is further summarized, according to one aspect, as follows. It includes a lock bar wherein the lock bar is rotatably attachable to a screen support structure, the lock bar being rotatable by movement of the trigger. The lock bar intercepts the rearward arc path of a blockable part (such as a flange extending laterally from the screen). The flapper is located and oriented with respect to the closed screen for at least part of the flapper to be rotatable in response to pressure from impact fluid.

Abstract: An automated and flexible architecture is provided that enables a plurality of component tests to be executed in various testing orders while imposing a test framework to mitigate adverse effects or results on previously developed tests. In one aspect, a computerized test system is provided. The system includes a test engine to execute a plurality of component tests. One or more application programming interfaces (API) are provided to selectively determine at a subset of the tests to execute, an execution order of the tests, or a fault response for the tests, if desired. The API determines a phase execution for the tests, where the phase execution can include a set up phase, an execution phase, a validation phase, a publishing phase, and a clean up phase, for example.

Abstract: The present invention relates to an apparatus for maximizing the blockage of fluid borne solid materials from passage through a catch basin into the downstream parts of a fluid flow channel, with minimum impact on the volume and rate of fluid passing through the channel. The apparatus comprises at least one filter sheet secured within the catch basin at a location above and covering a large proportion of the floor of the catch basin, an overflow wall separating the filter area from an unfiltered overflow area, and a diverter for directing incoming trash away from the overflow area and to the filter side of the overflow wall. Although the apparatus covers a large area within the catch basin, the overflow wall, overflow area, and clearance between the filter sheet(s) and the floor provide sufficient space for fluid and excess trash to pass in the event the capacity of the apparatus for holding them is exceeded.

Abstract: The present invention relates to an apparatus and method, using the apparatus, for blocking the passage of solid materials into or through a channel while permitting the passage of fluid; automatically releasing the blocked solid materials under predetermined conditions when priority is given to maximizing the passage of fluid; automatically re-closing after the accumulated solid materials have passed downstream, and resuming the blocking of solid materials; and, repeating the process upon recurrence of the predetermined conditions. Although the invention relates to street storm-water drainage channels, particularly inlets to catch basins, it can be applied to any fluid-flow channel where blocking the passage of solid materials is important but where there are conditions under which priority should be shifted from blocking the solid materials to releasing them downstream.
