The present invention relates to a highly reliable nonvolatile memory and a manufacturing method thereof. The nonvolatile memory comprises top electrodes, bottom electrodes and a resistive material layer disposed therebetween, wherein the top electrodes are positioned on top in the memory; the bottom electrodes are positioned on a substrate; metal oxide for forming the resistive material layer is doped with metal; and a metal oxygen storage layer is further disposed between the top electrodes and the resistive material layer. The manufacturing method adopts a method in which a doping method and a double-layer forming method are combined, so that the highly reliable and highly uniform resistive random access memory can be fabricated and accordingly the performance of the memory can be increased.

A method and system of operating an actual or virtual desktop or server and managing such desktops and servers involves a cache appliance serving desktop, operating system, and application objects to a managed machine. The objects are composited together to present a normal file structure to the user, with all user configuration and data stored in the desktop object. Management requirements are minimized to maintain operating system and application objects, while users maintain distinct and customizable desktops.

A computer-implemented method is disclosed for executing aggregate queries of composite relationships from an Entity-Relationship (ER) model which sources data from a plurality of heterogeneous and decentralised databases. The method comprises maintaining an ER model comprising a plurality of entities En for which data exists in one or more databases, and one or more relationships rn between those entities. An aggregate query is received relating to a composite relationship cr(r1, r2) involving entities E1, E2 and E3 wherein r1 is a relation between E1 and E2, and wherein r2 is a relation between E2 and E3. The computation of the aggregate query is optimized by selecting an aggregation strategy according to the relation between entities E1, E2 and E3, such that a single table aggregation strategy, a semi-join strategy or a join strategy is selected according to the relation between tables defining entities in the ER model.

The present invention extends to methods, systems, and computer program products for modeling party identities in computer storage systems. A federated identity fabric models identity data and relationships between portions of indentify data in computer storage systems in accordance with a uniform schema. The federated identity fabric can federate distributed identity and identity relationship data from computer storage systems within the variety of different computing environments. Code and metadata at computing environments associated with the federated identity fabric can interoperate to facilitate uniformly storing, accessing, modifying, deleting, and securing identity and identity relationship data within the federated identify fabric. Embodiments of the invention include utilizing an identity key table entry to locate party identity information and performing key transformations between different types of identity keys.

The invention relates to a shell-side multi-cavity multi-layer fixed-bed reactor. At present, the shell-and-tube fixed-bed reactors all adopt the structure of one chamber on the shell side, so the heat transfer is uneven, the heat exchange is insufficient, and the waste heat is not better utilized. The shell of the present invention is composed of an upper shell and a lower shell. In each shell, two shell-side baffles are arranged between the upper tube sheet and the lower tube sheet along the axial direction of the shell. The shell-side baffles separate the shell Divided into three cavities, reaction tubes are set in the cavities on both sides, and three semicircular baffles are set in the cavities on both sides, so the flow form of the heat exchange medium between the tubes is cross flow and parallel flow. The invention doubles the ability to manufacture large-scale reactors under the condition of existing equipment; the reactor can be applied to high-load catalysts, and has stable reaction, uniform heat transfer, sufficient heat exchange and more thorough utilization of waste heat.

The invention relates to a fixed-bed reactor, a shell side of which is divided into a plurality of chambers. Currently, all the fixed-bed reactors with shells and tubes adopt a shell-side structure as a chamber, thus causing uneven heat transfer, insufficient heat exchange and worse utilization of residual heat. Between an upper cannular plate and a lower cannular plate inside the shell of the invention, two shell-side baffles are arranged along the shell axial direction and divide the shell into three chambers, and reaction tubes as well as three semicircular traverse baffles are arranged inside the chambers at the two sides, thus forming cross current and parallel flow as a flow form of heat-exchanging mediums between tubes. Under the condition of existing equipments, the capacity of manufacturing large-scale reactors is doubled by the invention; the reactors are applicable for catalysts with high load and have balanced reaction, even heat transfer and sufficient heat exchange, and the utilization of residual heat is more complete.
