摘要： A feedstream comprising tar is fed to a solvent deasphalter wherein it is contacted with a deasphalting solvent or fluid to produce a composition comprising a mixture or slurry of solvent containing a soluble portion of the tar, and a heavy tar fraction comprising the insoluble portion of the tar. These fractions may be separated in the deasphalter apparatus, such as by gravity settling wherein the heavy tar fraction is taken off as bottoms, and the solvent-soluble fraction taken as overflow or overheads with the solvent. The overflow or overheads is sent to a solvent recovery unit, such as a distillation apparatus, wherein solvent is recovered as overheads and a deasphalted tar fraction is taken off as a sidestream or bottoms. The solvent or a portion thereof, recovered as overheads, may be then be recycled to the solvent deasphalter, or in a preferred embodiment, at least a portion of the solvent is steam cracked to produce a product comprising light olefins.

摘要： Crystalline scintillator materials comprising nano-scale particles of metal oxides, metal oxyhalides and metal oxysulfides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In one method, used to form oxyhalides and oxysulfides, metal salts are dissolved in water, and then precipitated out as fine particles using an aqueous base. After the particles are separated from the solution, they are annealed under a flow of a water saturated hydrogen anion gas, such as HCl or H2S, to form the crystalline scintillator particles. The other methods take advantage of the characteristics of microemulsion solutions to control droplet size, and, thus, the particle size of the final nano-particles. For example, in one method, a first micro-emulsion containing metal salts if formed. The first micro-emulsion is mixed with an aqueous base in a second micro-emulsion to form the final nano-scale particles.

摘要： A dynamic services infrastructure accepts data describing data resources and stores that data in a relational database from which it may be retrieved to handle service requests issued by application programs. The database stores Service Definition data which is initially supplied in the form of XML Service Descriptor documents which are then mapped into the database from which they may be accessed. Each Service Definition includes an input specification which identifies the address of a resource as well as the nature of the input data to be supplied to the resource with the request, and further includes an output specification which describes the nature of the output information which is supplied by the resource in response to the request. The Service Definition further includes information describing the service provider which supplies the resource, test information including fixed input and output values which permit the operability of the resource to be verified, update information which permits the infrastructure to insure that the Service Definition information is kept current, and security information which permits the system to validate users and provide secure encrypted information exchanges. When a client sends a request for services to the infrastructure, obtains the service description for the desired resource from the database, transmits an output information request to the address specified in said the service description, supplying input information meeting the specification contained in said particular service description to said particular resource, and receives and routs output information provided by said particular resource in response to said output information request to the executing application program.

摘要： Selecting a master node in a multi-node computer system is described. Each node of the multi-node computer system selects a timeout value (e.g., randomly). Each node starts a timer, which is set to expire at the selected timeout value of its corresponding node. The node with the timer that expires earliest broadcasts an election message to the other nodes of the multi-node computer system, which informs the other nodes that the broadcasting node is a candidate for mastership over the multi-node computer system. The other nodes respond to the election message upon receiving it. In the absence of a refusal message from one or more of the other nodes, the candidate is established as master node in the multi-node computer system and wherein the other nodes function as slave nodes therein.

摘要： In an application executing in multiple computers connected by a network, an instance of the application is deleted from a group of instances that share a resource, such as a database. Specifically the to-be-deleted instance is shut down, followed by deleting connectivity between the to-be-deleted instance and the network, and then deleting an object of the to-be-deleted instance. Each of these acts is performed automatically without user input, once the user issues an instruction to delete the to-be-deleted instance.

摘要： Techniques are provided for managing replicated data items in a cluster of shared nothing nodes. The techniques include synchronously propagating changes to one or more replicas, while asynchronously propagating changes to the remaining replicas. Because the replicas to which the change is synchronously replicated may be a relatively small percentage of the total number of replicas, the overhead associated with performing an update is reduced. The process of selecting which nodes are involved in the synchronous update operation may take into account a variety of factors, including which replicas are available at the time the update operation is being performed.

摘要： A group of shared-storage resources are being maintained as replicas by the nodes of a cluster. Each node in the cluster maintains a set of pointers to the members of the group. As membership changes, the set of pointers should be changed accordingly. For various, reasons, the set of pointers of a node are not changed and may point to shared-storage resources that are no longer members of the group and/or not point to shared-storage resources that are members of the group. By recording a history of membership changes in the shared-storage resources, and comparing the recording to what a node thinks the shared resources should be, an incorrect set of pointers can be detected and corrective active undertaken.

摘要翻译： 正在将一组共享存储资源作为集群节点的副本进行维护。 集群中的每个节点都维护一组指向组成员的指针。 随着会员资格的变化，应该改变指针集。 对于各种原因，节点的指针集不会更改，并且可能指向不再是组成员的共享存储资源和/或不指向作为组成员的共享存储资源。 通过记录共享存储资源中的成员变更历史，并将记录与节点认为共享资源相比较，可以检测到错误的指针集并进行纠正。
