Provides processing logic modeling and executing methods, systems and apparatus. These facilitate collaboration between business analyst and IT staff for process modeling and maintenance of the consistency between business level design and IT implementation design. A task is decomposed into sub-tasks and is represented by a tree. Annotations to the nodes of the tree are used to represent the relations between the sub-tasks. A processing logic is thus completed. When executing the processing logic, traversing the tree follows according to the annotations.

A compensated resistivity logging while drilling tool having axially asymmetrically spaced transmitters is configured to provide compensated resistivity measurements. In one exemplary embodiment, the tool includes first and second compensating transmitters, preferably deployed axially symmetrically between first and second spaced receivers. The tool further includes a plurality of transmitters deployed axially asymmetrically with respect to the receivers, e.g., on one axial side of the receivers. The compensating transmitters are configured to acquire a borehole compensation that may be subtracted from conventional phase and attenuation measurements.

Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on a predetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.

A multilayer biaxially oriented polypropylene film is disclosed which comprises at least three layers. The first layer is an outer layer comprising a first polymer which is a homopolymer polypropylene resin having a melting point of at least 155° C. The second layer is a core layer, having a melting point greater than 150° C. The core layer includes a blend comprising a second polymer which is a polypropylene homopolymer having a melting point of at least 155° C. and a third polymer having a melting point no greater than 145° C. The second polymer comprises from 20% to 80% by weight of the core layer while the third polymer comprises from 80% to 20% by weight of the core layer. The last required layer in the film is a sealant layer. The sealant layer comprises a fourth polymer having a melting point no greater than 145° C.

Disclosed are hydrogels wherein a polymer matrix is modified to contain a bifunctional poly(alkylene glycol) molecule covalently bonded to the polymer matrix. The hydrogels can be cross-linked using, for example, glutaraldehyde. The hydrogels may also be crosslinked via an interpenetrating network of a photopolymerizable acrylates. The hydrogels may also be modified to have pharmacologically-active agents covalently bonded to the poly(alkylene glycol) molecules or entrained within the hydrogel. Living cells may also be entrained within the hydrogels.
摘要:
A terminal is capable of transmitting an orthogonal sequence in a broadband wireless communication system. Operations of a transmitting end include generating a sequence corresponding to sequence allocation information of the transmitting end among a plurality of candidate sequences; generating a signal string corresponding to the sequence; and transmitting the signal string over a channel defined for transmission of the signal string.

A process for preparing compounds of chitosan saccharified with aminosugar, adopts chitosan derivatives, aminosugar derivatives and anhydride derivatives as raw materials to synthesize target products. The process comprises: covalently bonding an anhydride derivative as a bonding arm to an aminosugar derivative, so as to form a monosaccharide derivative having an end group of carboxyl; and then covalently bonding the monosaccharide derivative having an end group of carboxyl to a primary amino group of a chitosan derivative via the carboxyl, so as to form a compound of chitosan saccharified with aminosugar.
摘要:
A method and a system for distributing key of media stream are provided. The method comprises: determining, by a security management server, whether a domain to which the calling terminal belongs and a domain to which a called terminal belongs subscribe a key distribution protocol; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the calling terminal and the called terminal, if the protocol has been subscribed; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the terminal at the same side as the security management server, if the protocol has not been subscribed. By applying the disclosure, the key is generated by the security management server, so that complexity may be reduced for media stream key negotiation to facilitate promotion of media stream encryption service.
摘要:
A method of detecting the presence of an ion includes contacting a nucleic acid enzyme with a sample suspected of containing the ion, where the enzyme contains a ribonucleotide and is dependent on the ion to produce a product from a substrate, and measuring an amount of the product produced. The ion is Pb2+, and is in the presence of other ions.
