Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating data defining molecules. In one aspect, there is provided a method performed by one or more computers, the method comprising: receiving, from a user, a request to generate data identifying candidate molecules satisfying one or more molecular criteria; generating a collection of candidate molecules that satisfy the one or more molecular criteria; generating, for each candidate molecule in the collection of candidate molecules, one or more molecular scores that characterize one or more properties of the candidate molecule; filtering the collection of candidate molecules, based on the molecular scores, to remove a plurality of candidate molecules from the collection of candidate molecules; and after filtering the collection of candidate molecules based on the molecular scores, providing a representation of the collection of candidate molecules to the user.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating data defining molecules. In one aspect, there is provided a method comprising: receiving, from a user, data defining a chemical computation graph, wherein: the chemical computation graph comprises a set of chemical computation nodes and a set of edges; each chemical computation node is configured to perform operations comprising: receiving a set of input molecules; and processing the set of input molecules, in accordance with a sequence of one or more transformation operations associated with the chemical computation node, to generate a set of output molecules; and each edge connects a respective first chemical computation node to a respective second chemical computation node; and generating a set of candidate molecules using the chemical computation graph.

Abstract: An induction heating system can be adapted for shrink fitting a plurality of different assemblies. A plurality of tooling units associated to respective ones of the assemblies, each one having an appropriately configured induction coil and holder, can be provided. A computer can be used to control the delivery of electrical power to the induction coil in accordance with a heating recipe, and can be provided with an input device for inputting an assembly identifier allowing the computer to operate the control based on the right heating recipe.

Abstract: An engine mounting arrangement is provided for supporting a gas turbine engine. The mounting arrangement comprises a module adaptor mounted to an overhead or a ground based carrier for rotation about a substantially horizontal axis. The module adaptor extends horizontally from a base to an axially-opposed distal end having a first mounting interface configured for attachment to a module of the engine. The module adaptor holds the engine by the module to which it is attached and with the other engine modules projecting in a cantilever fashion from the supported module.

Abstract: One or more support elements radially extend through one or more openings defined in a turbine engine casing and are configured to centralize and at least partially support a rotor assembly of the engine during an engine disassembly or assembly procedure. The support elements are configured to transfer any rotor assembly weight loads to an engine casing while a bearing support of the rotor assembly is absent or removed.
