We present a type-theoretic framework for data stream processing for real-time decision making, where the desired computation involves a mix of sequential computation, such as smoothing and detection of peaks and surges, and naturally parallel computation, such as relational operations, key-based partitioning, and map-reduce.

New constructs for synchronization termed synchronization expressions (SEs) have been developed as high-level language constructs for parallel programming languages [8, 9]. Statements that are constrained by certain synchronization requirements are tagged, and synchronization requests are specified as expressions of statement tags.

Sociological studies of work and time have argued that academic temporalities are increasingly rationalized and rendered accountable, resulting in a divergence of planned and experienced time in academic work. Shared research facilities that provide platform technologies to large user pools are no exception to this, as its administrations seek to ...

In this work we study the synchronization between identical pairs of hyperchaotic mathematical systems symmetrically coupled. Calculations are performed firstly in two well-known hyperchaotic systems, and then compared with the results obtained coupling symmetrically two Takens–Bogdanov systems (TBS) which represent a bifurcation in Codimension 2 (a ...

Journal of Parallel and Distributed Computing, 2013
Most published concurrent data structures which avoid locking do not provide any fairness guarantees. That is, they allow processes to access a data structure and complete their operations arbitrarily many times before some other trying process can complete a single operation. Such a behavior can be prevented by enforcing fairness.

Synchronous Multiparty Synchronizations and Transactions
2008In this paper we analyze how a powerful synchronization mechanism such as synchronous multiparty synchronizations, which is able to specify atomic reconfigurations of large systems, can be implemented using binary synchronizations combined with a transactional mechanism.

Synchronization analysis for synchronized diving videos
2008 IEEE International Conference on Multimedia and Expo, 2008The judgements in some sports competitions are subjective tasks, especially in competitions with high requirements on skills, which could lead to unfair results. Synchronized diving is such a skillful competition. Using computer to judge competitions automatically or assist referees to judge can effectively decrease the unfair results.

Synchronization Failures in a Chain of PLL Synchronizers
IEEE Transactions on Communications, 1986In digital transmission systems employing PLL repeaters, timing jitter is produced mostly by intersymbol interference (ISI). Despite the fact that IS1 represents a narrow-band disturbance to the PLL for a long chain of N repeaters, it is responsible for cycle slips of the PLL repeater.

Synchronous ethernet: a method to transport synchronization
IEEE Communications Magazine, 2008This article discusses the evolving transport architecture, covering some of the synchronization distribution problems to many endpoints where mobile backhaul and TDM emulation occur. It shows how synchronous Ethernet fits into both the Ethernet and synchronization architectures, and discusses how this helped development in standardization bodies ...

Synchronizing transients and synchronizers for large machines
Electrical Engineering, 1940IT IS a curious fact that the phenomena encountered in synchronizing operations have received scant attention in the technical literature even though the phenomena have been encountered ever since two synchronous machines were first operated in parallel, and even though a large number of synchronizing operations are performed every day.
