The conventional Takagi-Sugeno (T-S) fuzzy model is an effective tool used to approximating behaviors of nonlinear systems on the basis of precise and certain input and output observations. In some situations, however, we can only obtain mixture of precise data (for input variables), imprecise and uncertain data (for output variable/response). This paper presents a method used to constructing T-S...
The aim of this paper is to advance the smoothing of original data sequence. According to the theory of prior using of new information, based on the present theories of buffer operators and some already existed weakening buffer operators, some new weakening buffer operators are established.They are compared with the existing weakening buffer operators in effectiveness.The problem that there are some...
Assessment index data missing value added model, fitness comprehensive assessment model and fitness index weight coefficient calculation model are set up based on the basic principles of artificial neural network, taking certain staff of one university in Shanghai as subjects. Precisions of learning samples and verified samples in assessment index data missing value added model are respectively 86...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
The problem of concern here is the parameter estimation of chirp signals in the presence of additive noise. An improved cyclostationarity based algorithm is proposed to estimate the phase parameters. The novelty of the proposed algorithm lies in the iterative estimation of the second-order parameters. The main characteristics of the method include reduction in error propagation effect, increase in...
