摘要： The present invention provides a method and system of material identification using binocular steroscopic and multi-energy transmission image. With the method, any obstacle that dominates the ray absorption can be peeled off from the objects that overlap in the direction of a ray beam. The object that is unobvious due to a relatively small amount of ray absorption will thus stand out, and the material property of the object, such as organic, mixture, metal and the like can be identified. This method lays a fundament for automatic identification of harmful objects, such as explosive, drugs, etc., concealed in a freight container.

摘要： A trace detector is disclosed. The trace detector comprises: a desorption chamber defining a desorption region, and the desorption chamber has a housing. The housing has a sample feeding port for introducing a substance to be detected into the desorption chamber and a gas discharge port for discharging gas entraining the sample from the desorption chamber. A controller is used for controlling the trace detector in such a manner that the sample feeding port and the gas discharge port are in fluid communication with the desorption chamber during pre-concentration process of the trace detector, thereby continuously feeding and collecting the sample. With the above manner, data collecting, processing and analyzing processes may be performed by the trace detector throughout the sample feeding process and the gas pre-concentrating process. The trace detector has an excellent detecting period of time whether the substance to be detected in the gas is in a high concentration state or a low concentration state, and the trace detector can perform continuous sampling for a long time, thereby improving a ratio of the amount of trapped substance to the amount of the substance entrained in the gas to be detected and the amount of the cumulated trapped substance, decreasing the probability of failing to detect the substance, and increasing detection sensitivity. In addition, the detection efficiency of the detector is increased during the gas pre-concentration process.

摘要： 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.
