    Abstract: A system and method for dynamic data race detection for concurrent systems includes computing lockset information using a processor for different components of a concurrent system. A controlled execution of the system is performed where the controlled execution explores different interleavings of the concurrent components. The lockset information is used during the controlled execution to check whether a search subspace associated with a state in the execution is free of data races. A race-free search subspace is dynamically pruned to reduce resource usage.

    Abstract: A system and method for analyzing concurrent programs that guarantees optimality in the number of thread inter-leavings to be explored. Optimality is ensured by globally constraining the inter-leavings of the local operations of its threads so that only quasi-monotonic sequences of threads operations are explored. For efficiency, a SAT/SMT solver is used to explore the quasi-monotonic computations of the given concurrent program. Constraints are added dynamically during exploration of the concurrent program via a SAT/SMT solver to ensure quasi-montonicity for model checking.

    Abstract: The present invention provides a method comprising the following steps: (a) partitioning an intensity modulated beam into a set of sub-IMBs; and (b) partitioning the sub-IMBs into segments, wherein steps (a) and (b) introduce no machine delivery error. The present invention also provides a method comprising the following steps: (a) recursively partitioning an intensity modulated beam into plateaus; and (b) partitioning the plateaus into segments, wherein step (a) comprises determining a tradeoff between machine delivery error and the number of segments into which the plateaus will be partitioned in step (b).

    Abstract: A three-stage pulse-tube cryocooler, in which the third stage pulse tube is arranged below the second stage pulse tube, with a gas flow conduit between the second stage pulse tube heat exchanger and the cold end of the second stage regenerator. The design of the invention is much simpler than a conventional three-stage parallel pulse tube cooler, requiring only two pulse tubes at the warm (room temperature) end and two reservoirs, with a corresponding reduction in the number of associated orifices, passages, etc. In effect, this provides a three stage cryocooler with a two-stage warm end design by putting the second and third stage pulse tubes in series, with a gas flow passage providing gas flow between the second and third stages for gas expansion and refrigeration. The three-stage design allows an intermediate temperature connection between the temperatures of the first and third stages, for applications which require three cooling temperatures.

    Abstract: A two-stage pulse tube cryocooler, having compact size, less vibration and lower manufacturing cost is disclosed, in which at least a first stage of the cryocooler is coaxial, but in which first and second stages may be coaxial by locating circular regenerators of each stage inside of corresponding annular pulse tubes. A second stage circular regenerator is installed below a first stage regenerator. This configuration allows preassembly of the regenerator assembly and a base tube assembly in one or more stages. The pulse tube, which is annular, is coaxially formed with an outside surface of the assembled regenerator assembly and an inner surface of the outer tube of the base tube assembly after installation of the regenerator assembly.
