Abstract: An abradable structure (36) is provided, with regions (44, 45, 46) with lower resistance to wearing produced by labyrinth seal lips (4, 5), at specific points in the axial direction of the turbomachine, where lip interference could cause the rotor to block up, such as after a temporary shutdown of the turbomachine. These regions may be produced by local weakening (38) or by the abradable material having a structure that is less dense. Application, for example, to turbomachine turbines.

Abstract: This concerns a sealing device between a rotor part and a stator part, comprising at least one abradable coating (46) cooperating with at least two upstream and downstream labyrinth seal lips. Axially upstream of the labyrinth seal lips, the sealing device comprises a circumferential wall (54) that radially extends beyond the upstream free axial sealing surface (48a) of the coating (46) to create, at the free end of the upstream labyrinth seal lip, a separation of the circulating gas.

Abstract: Technologies for optimized selection of content for delivery to a user that both optimizes the expected return from the delivery of the content to the user and that enables exploration of delivery of new content to users are disclosed. Content is selected for delivery to a user based on an exploitation score that defines an estimate of the feedback expected from the delivery of the content to the user and an exploration score that varies inversely with the number of times that the content has been transmitted to all users. The use of the exploration score enables the exploration of delivery of new content to users. The content might be delivered via e-mail messages, a web site, or using another mechanism.

The device includes a coating made of an abradable material attached to the stator section. The device further includes a lip on a portion of the rotor section. The lip is configured to form a seal with the abradable material. The gas turbine engine further includes passages for a gaseous fluid and means for blowing such gaseous fluid. The passages open into the rotor section provided with the lip, so that blown gaseous fluid can be present in a zone radially located between the coating and the lip.

Abstract: A system that verifies the attributes included in the description of an item using artificial intelligence is provided. For example, the system may use a feature extractor to identify color, shape, and/or texture features of a provided image. The system may then use a linear classifier to process the extracted features to identify attributes of the item depicted in the image. The system may compare the identified attributes with the attributes listed in the item's description. If there are any discrepancies, the system may revise the item description to include the identified attributes or provide suggested revisions to a user based on the identified attributes.

Abstract: Implementation of the sending of short messages to mobile networks with mobile number portability in the same country comprising a computer with SS7 connections able to interrogate all the HLRs of the country where MNP is implemented, being located in an other country or the same. The computer includes a memory cache for all the subscribers of the country which allow to know which HLR to interrogate without searching one they have been found. The memory cache is initially empty and builds once by search of the HLRs when a subscriber does not exist yet in the cache, or when he is ported-out, that is, change its network.
