    In order to deeply study the cultural connotation, shape, color and other artistic elements of the brick carvings of auspicious animals, the brick carvings of unicorns, magpies and cranes in the Han Dynasty were taken as research objects, and high-powered microscopes and 3D scanners were used as auxiliary tools for analysis. First of all, we refer to relevant historical documents to collect information on brick carvings. Then, the lines and colors of the brick carvings were mapped to find out the characteristics of the brick carvings of auspicious animals in the Han Dynasty. Finally, the characteristics of brick carving are integrated into modern cultural and creative design to provide support for cultural and creative design. The results show that the lines of brick carving in the Han Dynasty are soft, mainly seal carving, and the materials are mainly glazed and blue bricks. The color of brick carving is mainly based on the natural color of bricks, and some are characterized by the blue and yellow glass. The posture of the mascot animal carved in brick is gentle, but it does not lose its majesty, so it has the role of symbolizing auspiciousness and town. Therefore, the shape of the auspicious animal in the Han Dynasty is like a feather, the lines are soft, and the colors are mainly blue and yellow, which can provide a reference for cultural and creative design

    Risk Recognition is an important part in shipyard project risk management. The purpose of this paper is to explain how to identify risks by means of AHP. Firstly, we analyzed briefly the superiority of AHP in shipyard project risk Recognition; secondly, expounded the basic steps of risk Recognition based on AHP in shipyard project investment; then we proposed the principle and tips of applying AHP in identifying project risks by demonstrating a case of shipbuilding base. To prove the validity of AHP, we have identified the risk factors of the Shipyard project that mentioned in the case above, and have also calculated the influence weights taxis of dominating risk factors to the general risk. Key words: Shipyard Project Investment; AHP; Risk Recognition; Risk Factor

    Multi-Dimensional Recommendation Scheme for Social Networks Considering a User Relationship Strength Perspective

    Developing a computational method based on user relationship strength for multi-dimensional recommendation is a significant challenge. The traditional recommendation methods have relatively low accuracy because they lack considering information from the perspective of user relationship strength into the recommendation algorithm. User relationship strength reflects the degree of closeness between two users, which can make the recommendation system more efficient between users in pairs. This paper proposes a multi-dimensional comprehensive recommendation method based on user relationship strength. We take three main factors into consideration, including the strength of user relationship, the similarity of entities, and the degree of user interest. First, we introduce a novel method to generate a user candidate set and an entity candidate set by calculating the relationship strength between two users and the similarity between two entities. Then, the algorithm will calculate the user interest degree of each user in the user candidate set to each entity in the entity candidate set, if the user interest degree is larger than or equal to a threshold, this particular entity will be recommended to this user. The performance of the proposed method was verified based on the real-world social network dataset and the e-commerce website dataset, and the experimental result suggests that this method can improve the recommendation accuracy

    The water budget of a hurricane as dependent on its movement

    Despite the dangers associated with tropical cyclones and their rainfall, the origins of storm moisture remains unclear. Existing studies have focused on the region 40-400 km from the cyclone center. It is known that the rainfall within this area cannot be explained by local processes alone but requires imported moisture. Nonetheless, the dynamics of this imported moisture appears unknown. Here, considering a region up to three thousand kilometers from storm center, we analyze precipitation, atmospheric moisture and movement velocities for North Atlantic hurricanes. Our findings indicate that even over such large areas a hurricane's rainfall cannot be accounted for by concurrent evaporation. We propose instead that a hurricane consumes pre-existing atmospheric water vapor as it moves. The propagation velocity of the cyclone, i.e. the difference between its movement velocity and the mean velocity of the surrounding air (steering flow), determines the water vapor budget. Water vapor available to the hurricane through its movement makes the hurricane self-sufficient at about 700 km from the hurricane center obviating the need to concentrate moisture from greater distances. Such hurricanes leave a dry wake, whereby rainfall is suppressed by up to 40 per cent compared to its long-term mean. The inner radius of this dry footprint approximately coincides with the radius of hurricane self-sufficiency with respect to water vapor. We discuss how Carnot efficiency considerations do not constrain the power of such open systems that deplete the pre-existing moisture. Our findings emphasize the incompletely understood role and importance of atmospheric moisture supplies, condensation and precipitation in hurricane dynamics.Comment: 38 pages, 17 figures, 1 Table; extended analyses: available E/P ratios reviewed and explained (Table 1); rainfall and moisture distributions 3 days before and after hurricanes, propagation velocity and its relationship to radial velocity; efficiency for non-steady hurricanes; hurricane motion and rainfall asymmetries discusse
