Abstract: Embodiments are directed to managing data in a file system that includes a plurality of storage nodes and a plurality of storage volumes in a cloud computing environment. Metrics associated with each storage volume may be monitored. In response to the metrics exceeding a threshold value, performing further actions, including: determining storage volumes that are unhealthy based on the metrics that exceed the threshold value; updating metadata associated with the storage volumes to indicate that the storage volumes are unhealthy; decoupling the unhealthy storage volumes from storage nodes coupled to the unhealthy storage volumes; determining replacement storage volumes based on the metadata associated with the unhealthy storage volumes; updating other metadata associated with the replacement storage volumes to indicate that the replacement storage volumes are healthy storage volumes; and coupling the healthy storage volumes with the storage nodes that were coupled to the unhealthy storage volumes.

Abstract: Embodiments are directed to managing data in a file system that includes storage nodes and storage volumes in a cloud computing environment (CCE). A backup job may be executed to perform further actions, including: providing a backup identifier that is associated with the backup job; determining the storage nodes based on the file system and the CCE; disabling the file system by disabling the storage nodes, wherein each disabled storage node is associated with a shutdown timestamp; determining storage volumes associated with each disabled storage node; and generating storage images that archive a copy of information from the storage volumes; associating the storage images with the backup identifier; confirming that the file system is consistent based on an absence of file system activity occurring subsequent to each shutdown timestamp; and enabling the file system by enabling the storage nodes.

Abstract: Embodiments are directed to a file system engine that provides a file system that includes a plurality of blocks on a file storage tier with portion of the blocks associated with a cache storage tier. A cache engine provides heat extents that include a heat score and a run length value such that the heat extents are represent activities associated with the blocks. Heat extents associated with file system activities are determined based on a position of the blocks that corresponds with the run length values of the heat extents and sectors on the file storage tier. Heat scores associated with the heat extents may be modified based on the activities and distribution models to conform the heat extents with the distribution models. Blocks associated with heat scores that are less than a threshold value provided by the distribution models may be disassociated from the cache storage tier.

Abstract: A catheterization procedure training apparatus operable to provide a user training on the delivery of a catheterization process wherein the apparatus further allows the utilization of interventional devices. The catheterization procedure training apparatus includes a tubing network being hollow and fluidly coupled wherein the tubing network is configured to be sized and shaped so as to physically be proportionally representative of at least a portion of the blood vessels within a human circulatory system. A ventricle chamber is operably coupled to the tubing network. The tubing network further includes at least one opening having a union wherein the union is configured to be operably coupled to an exchangeable insertion point adapter. The exchangeable insertion point adapter includes a stem portion and a wall portion integrally formed and is configured to provide repetitive sealable use of a needle therethrough.

Abstract: A decorative laminate assembly having a decorative laminate top layer assembly. This top layer assembly includes, in descending superimposed relationship, a decorative layer and a core layer that includes PETG, or other polymeric material. Preferably, the top layer assembly also includes a wear resistant overlay layer on top of the decorative layer, and the core layer's PETG is in a sheet form. The top layer assembly may be directly bonded to a water resistant substrate. The decorative laminate assembly of the present invention can be used for a variety of purposes, including flooring applications. When the present invention is used for flooring applications, it is preferred that the overlay layer has enhanced wear resistant qualities and that the water resistant substrate comprise PVC or cement fiberboard.

Abstract: A mold tool for forming a reinforced matrix composite part for a gas turbine engine, comprising a body. The body comprises a body surface capable of receiving a first portion of a composite preform. A first endplate and second endplate are attached to the body and include a substantially planar surface disposed perpendicular to the body surface. A first and second set of plates are attached to the first and second endplate adjacent to the body surface and have a geometries that includes a first and second cavity bounded by the first and second plate and first and second endplate. The first and second cavities have a volume sufficient to receive a second portion of a composite preform. The second cavity is in fluid communication with the first cavity, which is in fluid communication with a vacuum source.

Abstract: A method for fabricating a reinforced matrix composite comprising the step of providing a composite preform having a fibrous structure and applying matrix material onto the preform in locations along the preform. A barrier material is applied to at least a portion of the coated preform to direct the flow of matrix material into the preform. The composite preform is heated to a temperature sufficient to render the matrix material viscous and insufficient to cure the matrix material. The pressure to the interior of the composite preform is reduced, while the pressure to the barrier material is increased. The temperature is maintained to flow the matrix material into the composite preform and to force gases from the fibrous structure. The composite preform is then cured and cooled to form a reinforced matrix composite having a low void content and a substantially uniform matrix distribution.

Abstract: The present invention relates to a novel composite adhesive used to adhere coating materials onto a substrate wherein the substrate material and the coating material have significantly different expansion properties, e.g., thermoplastic coating materials onto cellulose based substrate materials. The composite adhesive comprises both a rigid adhesive such as an epoxy or acrylic and a laminating adhesive such as a rubber based contact cement. In a preferred embodiment of the invention, a spline material is also rigidly adhered to the coating material so as to reinforce the bond between substrate and coating, especially where two pieces of coating material are attached at a seam. In another preferred embodiment the composite adhesive and/or spline material is used in preparing composite articles such as counters, sinks, furniture, profile edging, chemical resistant lab tops, showers, etc.
