This paper presents a characterization of an underwater positioning system based on surface nodes equipped with GPS and acoustic transducers. The positioning system calculates the coordinates of an underwater vehicle in one of the surface nodes or beacons, by the emission, detection, and reply of acoustic encoded signals. The characterization of the system has been performed by means of a statistical study, considering different numbers of beacons, beacons’ position and physical phenomena, such as noise, multipath, and mems. The error propagation caused by these phenomena and the geometrical configuration of the system has been quantitatively assessed in different positioning algorithms, based on trilateration and iterative procedures. The results show how the different phenomena affect the vehicle estimated position errors for the different positioning algorithms. In addition, the obtained errors inside the projected area of the beacons are ∼1 m or lower, rising to a few meters for the worst case scenario, showing the feasibility of the acoustic positioning system

Microblog platforms have been extremely popular in the big data era due to its real-time diffusion of information. It’s important to know what anomalous events are trending on the social network and be able to monitor their evolution and find related anomalies. In this paper we demonstrate RING, a real-time emerging anomaly monitoring system over microblog text streams. RING integrates our efforts on both emerging anomaly monitoring research and system research. From the anomaly monitoring perspective, RING proposes a graph analytic approach such that (1) RING is able to detect emerging anomalies at an earlier stage compared to the existing methods, (2) RING is among the first to discover emerging anomalies correlations in a streaming fashion, (3) RING is able to monitor anomaly evolutions in real-time at different time scales from minutes to months. From the system research perspective, RING (1) optimizes time-ranged keyword query performance of a full-text search engine to improve the efficiency of monitoring anomaly evolution, (2) improves the dynamic graph processing performance of Spark and implements our graph stream model on it, As a result, RING is able to process big data to the entire Weibo or Twitter text stream with linear horizontal scalability. The system clearly presents its advantages over existing systems and methods from both the event monitoring perspective and the system perspective for the emerging event monitoring task.

FSM EQUIVALANCE

Due to the channel achieving property, the polar code has become one of the most favourable error-correcting codes. As the polar code achieves the property asymptotically, however, it should be long enough to have a good error-correcting performance. Although the previous fully parallel encoder is intuitive and easy to implement, it is not suitable for long polar codes because of the huge hardware complexity required. In this brief, we analyse the encoding process in the viewpoint of very-large-scale integration implementation and propose a new efficient encoder architecture that is adequate for long polar codes and effective in alleviating the hardware complexity. As the proposed encoder allows high-throughput encoding with small hardware complexity, it can be systematically applied to the design of any polar code and to any level of parallelism.
