Pervasive computing systems are heterogenous and complex as they usually involve human activities, various sensors and actuators as well as middleware for system controlling. Therefore, analyzing such systems is highly non-trivial. In this work, we propose to use formal methods for analyzing pervasive computing systems. Firstly, a formal modeling framework is proposed to cover main characteristics...
Formal methods have been widely used in computer science and being improved day by day. Towards finite relation models, this paper advances a new formal method used by sextuple based on symbolic logic. It can use simple formal normative language to depict the relation between the modules in model exactly. With logical reasoning, it can analyse the models with theorem proving and model checking. In...
G-layer of RGPS requirement meta-model is used to refine the general business goals acquired on the basis of the Role layer. A business goal is a high-level and general statement when first proposed. Whether it can be achieved or not depends on the correctness of goal decomposition. Towards these problems, a decomposition model is proposed in this paper. Particularly, with the development of semantic...
Affective computing has been investigated by many to allow computers to respond to or react to human or user emotion. In this paper, a model of personality and emotion was proposed based on the architecture of a cognitive system. Considering the external and internal factors of a virtual agent, formalized description of the emotional model was built. Experiment results indicated that the emotion generated...
