Abstract: A computer implemented method for the verification of concurrent software programs wherein the concurrent software program is partitioned into subsets named concurrent trace programs (CTPs) and each of the CTPs is evaluated using a satisfiability-based (SAT) symbolic analysis. By applying the SAT analysis to individual CTPs in isolation the symbolic analysis is advantageously more scalable and efficient.

Abstract: A method and system for packet transmission in a hybrid automatic repeat request (ARQ) system. A modulation and a block length for a transmission are determined based on the average mutual information per bit. The average mutual information per bit is computed based on a current channel signal-to-noise ratio and a plurality of previous transmissions, each being transmitted with a respective coded block length, modulation form, and signal-to-noise ratio. A block error rate is computed for the potential block lengths and modulations based on the average mutual information per bit, and a throughput of the current transmission is determined based on the block error rate. The modulation form and the block length of the transmission are determined based on an analysis of the throughput. If the receiver cannot decode the current transmission, the transmitter repeats the computation to determine the modulation and the block length for retransmission.

Abstract: In accordance with exemplary embodiments of the present invention, a content addressable data structure system may include directed acyclic graphs (DAGs) of data content that are addressed using both a user-defined search key and content of data blocks. Internal keys of retention roots of the DAGs may be derived from the user-defined search key while the remaining blocks may be content addressed. As opposed to using a content address, the user may provide the search key when retrieving and deleting DAGs retaining the data content. In addition, the internal keys may be implemented using internal content addressable storage operations, such as applying a hash function and employing a distributed hash table.
