Texture synthesis is an essential aspect in virtual reality, making it an important research area in recent years. A new texture synthesis algorithm is proposed in this paper. Using the Direction Empirical Mode Decomposition (DEMD), the inherent direction of the sample textures is calculated and the samples are decomposed into a series of images. Based on(More)
In this paper, for real-time embedded software we consider the problem of checking component-based designs for scenario-based timing specifications. By adding time intervals on the actions, we extend the interface automata for modelling real-time systems. The component-based designs are modelled by real-time interface automaton networks, which includes a(More)
The growing scale and complexity of the enterprise computing systems under distributed and heterogeneous environments present new challenges to system development, integration, and maintenance. In this paper, we present a model driven Web service development framework to combat these challenges. The framework capitalizes on the UML profile for Enterprise(More)
This paper presents a method to reconstruct a 3D garment model from a sketchy garment contour, there are three features with our method: firstly, a reference model of 3D human is established by restricting the direction of the distance field (only direction along z-axis is considered), and it makes the computation of distance field much easier; secondly, an(More)
Gamma-linolenic acid (gamma-linolenic acid, GLA; C18:3 Delta(6, 9, 12)) belongs to the omega-6 family and exists primarily in several plant oils, such as evening primrose oil, blackcurrant oil, and borage oil. Delta(6)-desaturase is a key enzyme involved in the synthesis of GLA. There have been no previous reports on the genes encoding Delta(6)-desaturase(More)
In component-based software development, an important problem is behavioral incompatibility in component compositions. That two components are behaviorally incompatible means that they cannot work together due to the mismatching order of exchanged messages between them. One of the approaches to solving this problem is to construct an environment for the(More)
