Abstract: Lightweight mechanisms provide a way to assert provenance when live streaming media content and establish provenance upon playback. For example, a provenance claim generator generates a key pair including a live-stream private key and live-stream public key. The claim generator signs, with a long-term private key reliably associated with a sender, manifest metadata including the live-stream public key, thereby producing a manifest signature. During live streaming, the claim generator signs respective portions of media content with the live-stream private key, producing portion signatures for the respective portions. A provenance claim validator receives the manifest signature and manifest metadata. The claim validator verifies the manifest metadata using a long-term public key (reliably associated with the sender) and the manifest signature.

Abstract: A method for evaluating the health status of a petrochemical atmospheric oil storage tank using data from multiple sources. The health status of an atmospheric oil storage tank is influenced by multiple factors, and is evaluated by: acquiring corresponding sensor data and comprehensively considering the sensor data along with basic data of the oil storage tank, and selecting from a dynamic monitoring parameter-based health status and a basic health status of the oil storage tank, the one having a greater severity level, so as to determine the final health status of the oil storage tank. The method is used to conduct a comprehensive scientific assessment of the health status of an oil storage tank, and improves the use safety of the oil storage tank.

Abstract: Aiming at insufficient drying seafood on-board caused by hull swings, the present invention involves the establishment of location correction system for processing seafood transportation displaced by wind waves and anti-accumulation drying processing method. This invention employs CFD-DEM method to simulate the state and distribution of the material particles modulated by the deflector angle and wind speed. Finally, the optimized rotation angle of deflector and wind speed are obtained where material particles are equally distributed. Meanwhile, the uniform and fast drying of the marine products in the swinging hull are achieved. This invention shows the great advantages of high efficiency, automation and continuity.

Abstract: According to various embodiments, a machine-learning based system for simulating tropical cyclones (TCs) and assessing TC risk is disclosed. The system includes a hierarchical Poisson genesis module configured to develop a Poisson regression and TC genesis simulation on a plurality of clustering grids. The system further includes an analog-wind track module configured to determine movement of a TC by both analog predictors formed by historical track patterns and current in situ wind. The system additionally includes a Markov intensity module configured to determine intensity change of the TC by considering three hidden discrete states of storm intensity change and associating each state with a probability distribution of intensity change.

Abstract: A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.
