Abstract: In a binocular steroscopic scanning radiographic imaging method, X-rays emitted by the same radiation source are used. The X-rays pass through a double-slit collimator to form two X-ray beam sectors, which are symmetric or asymmetric and have an angle between them. The X-ray beam sectors, after penetrating through an object under detection, are received by the left and right detector array, respectively, then converted into electric signals to be inputted to the respective image acquisition systems, and received by a computer processing system for image processing and displaying. A system corresponding to the method comprises a radiation source, a beam controller, two mutually connected arms of detector arrays, image acquisition systems connected respectively to each of the detector arrays and a computer processing system. The present invention can display the transmission images detected by each of the detector arrays as well as tomograms with different depth reconstructed from the transmission images according to the principle of parallax. The present invention is convenient, fast in detection and realizes with low cost the recognition of objects of different depths.

Abstract: A system and method for aggressive loop parallelization using speculative execution is disclosed. The method may include transforming code of a target application for concurrent execution, which may include adding an instruction to create a global address table entry for each store operation on which a load operation of a different loop iteration is dependent. The method may include replacing a standard load instruction with a special instruction configured to determine if an operand address of the load matches an operand address in one of the global address table entries. Another special instruction may remove a table entry following execution of the corresponding store operation. If an operand address of a load of a currently executing thread matches an operand address in the global address table, the method may include setting a checkpoint, completing execution of the thread in a pre-fetch mode, and re-executing the thread from the checkpoint.

Abstract: A detection apparatus and method for an ion migration spectrum include acquiring an ion migration spectrum of pure carrier gas and an ion migration spectrum of carrier gas containing a test substance sample and performing differential process on the ion migration spectrum of the pure carrier gas and the ion migration spectrum of the carrier gas containing the test substance sample to acquire a differential spectrum. The value of a characteristic peak of the differential spectrum represents properties of the sample of substances. The method avoids interferences on the migration spectrum from interference sources of the apparatus itself, thereby improving detection sensitivity and accuracy of the ion migration spectrum, and migration spectrum shift caused by variations in the environmental conditions can be found and corrected through the differential process on the migration spectrum of the pure carrier gas, thereby achieving self-stableness and self-correction of the ion migration spectrometer.
