Research on the influence of specific hydrological environment change on current velocity and water exchange has a long history in oceanography; however, the majority of previous work has been based on traditional ocean models such as POM and FVCOM. This paper presents a stable joint method that combines a support vector machine with a hydrological model to predict current velocity in different hydrological...
This paper establishes three models of dynamic input-out economic systems with multiple delays. Uncommonly, the systems are with probably singular capital coefficient matrices which are greatly common in practical economic models. By equivalent transformation, the economic models are written as three discrete-time singular systems with multiple delays. Furthermore, three admissibility conditions are...
University students have been the most important online consumer group. Accordingly, this research intends to build up a university student behavioral intention model originally based on technology acceptance model (TAM), to explore the contributing factors of intention of online shopping and their interactive relationships. We conducted sampling survey of students from Guangzhou Higher Education...
Risk assessment is applied to the study of urban waterlogging. A series of methods which are suitable for the risk study of urban waterlogging are presented. Based on the hydraulic model built by InfoWorks Collection System software, the situation of normal state/ pump failure under special return period is simulated. Also, the seeper depth and recoverability theory are selected as the quantitative...
One of the most prevalent security problems in network is the rampant propagation of email worms. In this paper game theory is suggested as a method for modeling and computing the probabilities of expected behaviors of email users in the email worm propagation process. The game situation models the actions of the email users under the condition that at the time they open an attachment, the system...
The Lagrangian circulation in Changjiang Estuary, Hangzhou Bay and their adjacent sea area is simulated, with the riverine discharge, East China Sea Current, wind, the major tidal components, and the density gradient taken into account. The modeled outputs show that surface circulation pattern is similar to depth-averaged one both in summer and in winter. The Taiwan Warm Current is stronger due to...
