High-resolution climate simulations are increasingly in demand and require tremendous computing resources. In the Community Earth SystemModel (CESM), the Parallel Ocean Model (POP) is computationally expensive for high-resolution grids (e.g., 0.1°) and is frequently the least scalable component of CESM for certain production simulations. In particular, the modified Preconditioned Conjugate Gradient...
This paper presents a simple method for modeling smoke from a single view, which could preserve fine realistic look observed from different views. Thin translucent smoke, generated by cigarette, candle, joss stick et al, is the main focus of this paper. The proposed method initially computes the smoke intensity from the input key frame image, then partitions the smoke into multiple segments. For each...
This paper presents a resource management model of power system based on grid technology, users can use this model to structure grid management platform that provides various services, make full use of the distributed resources to process large-scale computing and simulation.
In minimally invasive surgery, steerable needle is needed to perform medical tasks in the deep of a human body. In some cases, a one-direction bendable needle can satisfy actual needs. Therefore, a one-direction bendable articulated needle is proposed in this paper. The proposed needle consists of a beveltip head, articulations, and sections. Articulations can only be bent along the tip direction...
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...
This paper presents a real-time soft shadow rendering algorithm based on the shadow-mapping technique. The key idea of this algorithm is to use only a single shadow map for a flat extended light source. The algorithm also uses the single shadow map to discretize the occluders to many flat patches which are parallel with the light source. Finally, these patches are used to compute the percentage of...
