Abstract: A method for symbolic model checking for sequential systems using a combination of state-based and state-less approaches. A state-based method is used to compute frontier states by building transition relations on-the-fly using control flow information of the system, and performing successive image computations until a memory bound is reached, and efficiently storing only the new frontier states as disjunctive partitions of Boolean and Arithmetic expressions. A stateless method is used to check reachability of given goal states from a heuristically chosen set of frontier states until depth/time bound is reached. These two methods are alternated until one of the following occurs: all frontier states are explored, all goal states are reached, all computing resources are exhausted. Even though we do not store the entire reachable state set, we guarantee a complete coverage for terminating programs without the need to compute a fixed-point.

Abstract: A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring then the transmission guide rod retracts into the casing and closes.

Abstract: A method and device for feeding back downlink channel feedback information, and a method and device for user pairing. The method for feeding back downlink channel feedback information includes: calculating the multi-user channel quality indication error of a user, which error is used to reflect the difference in channel quality indication between the situation of multi-user multiple input multiple output transmission and the situation of single user multiple input multiple output transmission; adding the multi-user channel quality indication error into the downlink channel feedback information which includes a pre-coding matrix indication and a channel quality indication, and feeding the same back to a base station for scheduling. Therefore, the bit error rate of demodulation in the MIMO system can be reduced and the system performance can be improved.

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.
