摘要:
Techniques used in a relational database system for defining subclasses of built-in classes and thereby achieving columns in database tables which contain polymorphic objects of the built-in classes. The methods for the subclasses are contained in named packages. A table in the database system's schema relates the package name to a storage location managed by the relational database system that contains the compiled code for the package. When a method from the package is invoked, a dynamic linker uses the name and the table to locate the compiled code and then executes the compiled code. One thing that can be done with subclasses is to use a database system to automatically connect a Web user with a server of streaming data. The connection thus established is made by the server of streaming data to the Web user and thus bypasses the database system.

A waveform generator for providing an analog output signal to a target device includes a look-up-table (LUT) that stores a plurality of binary address values and a digital-to-analog converter (DAC) that generates the analog output signal. The waveform generator receives an input trigger signal from the target device when the target device is ready to receive the analog output signal. The waveform generator generates a synchronized input trigger signal and aligns the analog output signal with the synchronized input trigger signal by reloading the LUT with a binary address value of zero.

Apparatus, methods, and computer program products are disclosed that present a delegated-right to a delegation system by a service-application provisioned with the delegation system. The delegated-right enables the service-application to perform an operation/access on behalf of a delegator-user. The method then attempts to perform the operation/access.

摘要:
There is disclosed a system and method for network test conflict checking. The method may be performed by a network testing system and may be implemented as software. The method may include receiving user selected test features and user selected hardware for a network test. When receiving user selected features, incompatible features are made unselectable by reference to a feature database. A compatibility check is performed by referring to a hardware database and a feature database. Suggestive corrective changes may be provided to a user or automatically made to the selected features and/or selected hardware. The network test is written to hardware when the compatibility test is successful.
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:
Crystalline scintillator materials comprising nano-scale particles of metal halides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In these methods, ionic liquids are used in place of water to allow precipitation of the final product. In one method, the metal precursors and halide salts are dissolved in separate ionic liquids to form solutions, which are then combined to form the nano-crystalline end product. In the other methods, micro-emulsions are formed using ionic liquids to control particle size.

A syndicator for disseminating Web services and other resources from service and content providers to service consumers and for establishing and implementing subscription agreements specifying the terms upon which digital assets are provided to subscribers. A registration database stores a service description for each of a plurality of different Web services and other resources. Each stored service description contains an input processing specification, an output processing specification, and the specification of the business terms upon which the described service or resource is offered by its provider to subscribers. A subscription manager conducts a negotiation with a prospective subscriber and receives from the subscriber an acceptance of the business terms upon which a specified Web service or resource is offered to establish a subscription agreement. Event tracking records information describing the performance of each service on behalf of each subscriber to perform subscription accounting functions.
