Abstract: A method is provided for reserving, maintaining and releasing resources in the interior nodes located within an interior network positioned between edge nodes, wherein requests belonging to corresponding data microflows that continually arrive at any interior node do not establish any microflow reservation states, but these requests can establish, maintain and release either a part of, or an entire aggregated reservation state, using a combination of reservation soft state and explicit release principles. A window is applied to establish a first time period, which includes a selected cell in a sequence of time cells and also includes a number of additional cells preceding the selected cell. Arrival of reserve and refresh requests during the selected cell is detected to generate an rfcount associated with the selected cell.

Abstract: A system and method for generating motion and trajectory data for a multi-gimbaled rotating platform. The system includes a motion generating unit for generating a set of motion equations for each degree of rotational freedom of the multi-gimbaled rotating platform, where each set of motion equations defines the rotational movement of the platform about a gimbal pivot axis between a starting position and an ending position.

The set of motion equations simulating movement of the rotating platform may be further utilized to generate trajectory data for the object being supported by the platform, so that the effect of the motion of the rotating platform on the object can be simulated without requiring the rotating platform to be actually moved in a field test.

Abstract: A processor having an execution result prediction function for an instruction that performs a branch/value prediction by which a high percentage of correct predictions can be realized ought to be provided. Accordingly, in a branch/value prediction circuit having a set associative, a priority of an entry used for a prediction is increased only when an execution result is referred to for the prediction and the prediction is correct, and the execution result is registered in the entry of the lowest priority when the execution result for the instruction is newly registered in a history table. Thus, the entry of a low percentage of correct predictions becomes easy to erase and prediction accuracy can be increased by updating the priority only when the prediction is correct.

Abstract: Methods are provided for virtually embedding and/or de-embedding balanced four-port networks into/from a device under test (DUT). For the methods, a set of scattering-parameters is acquired for the DUT. Additionally, a respective set of scatter-parameters is acquired for each of the balanced four-port networks to be embedded and/or de-embedded. A transfer-matrix is generating for the DUT based on its scattering parameters. Further, a respective transfer-matrix is generated for each of the networks to be embedded/de-embedded based on its respective set of scattering-parameters. The transfer-matrix for the DUT is then multiplied with the one or more transfer-matrices associated with the balanced four-port networks to be embedded and/or by an inverse of the transfer-matrices associated with the balanced four-port networks to be de-embedded. A composite transfer-matrix is thereby produced. Finally, a set of composite scattering-parameters is then generated based on the composite transfer-matrix.

Abstract: A method and device applicable to HV generators and X-ray tubes, and a computer program and support for the program. In the method a determination is made of a scale of values representing the energy of the radio-frequency spectrum transmitted by radio wave over a given period in the electric discharges appearing in the system for a given test voltage, by artificially varying in the system the level of pollution of the system until dielectric failure of the system. A limiting value is chosen embracing the admissible pollution tolerances on manufacture. A measurement is made for each system of the same product type of the quantity of energy of the radio-frequency spectrum transmitted by radio wave by each of the systems under the same conditions. A comparison is made of the quantities measured with the limiting value chosen to determine a possible fluctuation of quality of the systems produced.
