Abstract: A computer-implemented method is provided for rendering, to a designer, a two-dimensional image of an assembly of part instances in a three-dimensional assembly space within a computer-aided design (CAD) system utilizing double precision to describe part assemblies. Such assemblies are considered to be distant from a nominal observer. A viewport on a two-dimensional image plane is defined, and a combined transform is defined in quadruple precision to enable the generation of clipping lines and/or clipping points. The clipping lines and clipping points clipping the faces and edges of the part instance in the assembly to the portion of the assembly that lies within the viewport.

Abstract: A computer-implemented method of handling large transforms in a computer-aided design (CAD) solid model utilizing double precision to describe a physical assembly of parts is described. If the unit size of a transform of interest exceeds a pre-determined threshold, the double precision of the transform is converted to quadruple precision whilst maintaining the double precision of the assembly. The results of any operation are output in double precision. A computer program and method of adapting an existing CAD model are also described.

Abstract: A computer-implemented method of determining the dimensions of a space-filling lattice in a solid model is disclosed, wherein information including a lattice, a set of faces, and data indicating a spatial relationship between the lattice and each face in the set is received. A set of points indicating the intersection positions where each rod intersects a face is identified, and each intersecting rod is classified based upon whether or not each subset of mutually tolerantly coincident points within the set indicates that a rod is divided by a face. If a rod is divided, the lattice is modified by adding a new ball where the rod is divided and classifying the new rods either side of it. These classifications are spread to adjacent rods without crossing any new ball to establish the complete set of surviving rods. Each connected set of surviving rods is used to instantiate a new lattice.

Abstract: A computer-implemented method of extending a mixed sheet within a B-rep model is described. The mixed sheet includes surfaces having different geometries, such as a mesh positioned between first and second classical geometry surfaces. A first guide curve is defined, located at the boundary of a first surface for a length corresponding to the desired mixed sheet extension adjacent the first surface. A second guide curve may also be defined, located at the boundary of a second surface for a length corresponding to the desired mixed sheet extension adjacent the second surface. At least one extension mesh rung is created by generating facets between the two external mesh vertices using first and second extension vectors, wherein the first extension vector has a pre-determined spatial relationship to the first guide curve. If included, the second extension vector has a pre-determined spatial relationship to the second guide curve.

Abstract: Systems, methods, and non-transitory computer readable media are configured to receive a signal. One or more data streams associated with one or more metrics associated with the signal can be determined. The one or more data streams can be sampled to generate data samples. A grade associated with the signal can be generated based on the data samples. The grade can indicate quality of the signal.

Abstract: A flexible pipe for subsea transportation of production fluids, a method of manufacturing flexible pipe body and a method of providing corrosion protection to armour wires of at least one tensile armour layer of a flexible pipe having a breached pipe annulus are disclosed. The flexible pipe comprises a fluid retaining layer, an outer sheath and at least one tensile armour layer comprising a plurality of helically wound monofilament armour wires of a first material, each having a non-circular cross section with an aspect ratio of greater than 1:2 disposed between the fluid retaining layer and the outer sheath. The tensile armour layer further comprises at least one helically wound elongate anode element substantially having a cross-section aspect ratio of 1:1 and comprising a further material, interposed between armour wires, the anode element cross section having an area that is 50% or less of a corresponding area of said non-circular cross section.

Abstract: An embodiment of a method of providing identity assurance for a decentralized application (DApp) includes executing, by at least one distributed node of a blockchain system, an entitlement contract stored on the blockchain to perform a read call from a DApp contract stored on the blockchain, the read call including an address signing a transaction to the DApp contract. Performing the read call may include reading a list of registered addresses stored on the blockchain, determining whether the list includes the signing address; and providing an output indicating whether the list includes the signing address. The method may further include executing, by the at least one distributed node, a registry contract stored on the blockchain to perform a read call from the DApp contract, the read call including an identifier of the decentralized application.

Abstract: Computer-readable media, systems and methods may improve security, authorization, and auditability of documents. For example, computer systems for serving documents may be improved to provide secure access and control through challenges that are validated with self-executing on-chain document license contracts that enforce entitlements that specify users and their authorized document actions. Such entitlements may be generated by the user who created the document. As such, a user may retain over authorizations and document actions that are permissible with respect to the document even after the user has transferred a copy of the document. Furthermore, the computer systems may be improved to write an on-chain audit log of document actions, providing an immutable record of the document actions.
