Abstract: A propulsion system includes a drive shaft that rotates about an axis, a fan, a fan shaft that drives the fan about the axis, a reduction mechanism coupling the drive and fan shafts, a compression section driven by the drive shaft, and an inlet channel that extends between the fan and the compression section. The inlet channel includes inner and outer ferrules delimiting an air inlet flow path, the inner ferrule having a minimum radius. The reduction mechanism includes two reduction stages including two or more planet gears circumferentially distributed around the axis, each planet gear including a first portion meshed with the drive shaft and a second portion meshed with the fan shaft and being mounted fixed with respect to the inner ferrule and having a maximum radius greater than the minimum radius such that the air inlet flow path extends partly between the two or more planet gears.

Abstract: A terminal device for a cable with mineral insulation, including a metal bushing of which one end is intended to be secured to the end of the cable and a ceramic insulating element. The ceramic insulating element is a cylinder accommodated in the bushing, with one end projecting from the bushing and its opposite end, which has a bore, accommodated in the bushing, the end of the cylinder that is accommodated in the bushing having a tapered shape.

Abstract: A face milling tool includes a tool body having an axial front end surface with several seats. Each seat has support surfaces for rotationally locking and supporting a tangential cutting insert in the seat. One of the support surfaces is a flat axial support surface for supporting the tangential cutting insert in an axial direction defined by the central rotation axis. The flat axial support surface extends perpendicular to the central rotation axis and is situated axially foremost in the seat. A side wall of each seat is formed out of round side support surfaces. Each tangential cutting insert includes an axial back side with a flat axial contact surface abutting the flat axial support surface and a projecting member extending axially from the flat axial contact surface and having a circumferential side surface forming out of round side contact surfaces abutting the out of round side support surfaces.

Abstract: Technologies are provided for identifying a source of errors within a computer network that uses cut-through forwarding of network packets. For example, inbound network packets can be received by network devices configured to perform cut-through forwarding. Once the network packets are received, they are processed using cut-through forwarding. If any packet errors are detected, error data associated with the detected errors are stored by the network devices. The error data is transmitted to a monitoring service that uses the error data to create a model of a flow of the errors through the network and to identify a source of the errors. In at least some embodiments, a topology of the network is used by the monitoring service to create the model of the packet error flow.

Abstract: A cutting tool has a tool body having at least one pocket, at least one cutting insert releasably fixed to the pocket and a fastening device for securing the insert in the pocket. The pocket has a raised portion) with a flat upper support face arranged to be received in a recess of the insert and support the insert by receiving a bottom surface of the recess bearing on the support face. A projecting member of the raised portion has delimiting walls designed to bear against border walls of the recess of an insert for establishing mutual contact therewith and prevent rotation of the insert in the pocket by receiving a rotational moment acting on the insert in an active chip-removing state of the tool.

Abstract: A method for compiling code includes receiving a code section representation including a guard at a location, placing, at the guard, a triggering condition, and relocating the guard from the location to a second location in the code section representation. The method also includes transforming the guard into a control-split instruction. The control-split instruction includes a deoptimization branch and a continue execution branch. The method further includes placing, at the guard, a deoptimization instruction, and selecting a symbolic frame state linked to a side-effecting instruction. The side-effecting instruction is the last side-effecting instruction before the control-split instruction. The method also includes linking the deoptimization instruction with the symbolic frame state based on the symbolic frame state being linked to the side-effecting instruction, unlinking the symbolic frame state from the side-effecting instruction, and storing the code section representation.

Abstract: A method for a compiler includes receiving, by the compiler and from an interpreter, a representation of a code section having a control path that changes the representation. The representation has profiling data, and the profiling data has a threshold. The method further includes performing, by the compiler and based on the threshold, a partial evaluation of the interpreter executing the representation, compiling, by the compiler, a machine code of the representation, with the control path replaced by a deoptimization point during the compilation of the machine code, triggering the deoptimization point during execution of the machine code, and returning execution to the interpreter based on the triggering.
