The Takagi-Sugeno (T-S) fuzzy multiple-variable integral control system with fuzzy state observer is designed for the coordinated control of multi-input-multi-output (MIMO) nonlinear boilerturbine system whose operating points vary within a wide range. Linear models are first derived from the original nonlinear model on several operating points. Next the fuzzy multi-variable integral controller...

In terms of observational data, there are some problems in the standard Big Bang cosmological model. Inflation era, early accelerated phase of the evolution of the universe, can successfully solve these problems. The inflation epoch can be explained by scalar inflaton field. The evolution of this field is presented by a non-linear differential equation. This equation is considered in FLRW model...

Acoustic scattering by three-dimensional obstacles is considered, using boundary integral equations, null-field equations and the T-matrix. Connections between these techniques are explored. It is shown that solving a boundary integral equation by a particular Petrov–Galerkin method leads to the same algebraic system as obtained from the null-field equations. It is also emphasised that the T-ma...

A bstract We study a Hermitian matrix model with the standard quartic potential amended by tr( R Φ 2 ) term for fixed external . This is motivated curvature in truncated Heisenberg algebra formulation of Grosse-Wulkenhaar — renormalizable noncommutative field theory. The extra breaks unitary symmetry action and leads, after perturbative calculation integral, to an effective multitrace model. Ac...

DeLone and McLean’s Information Systems Success model was validated empirically in many developed countries. However, it was not tested in Low-Income Countries (LICs) context where IT infrastructure is a serious hurdle for IS success. Testing the Model in LIC context assures generalizability and relevance of the model. This study looks at two research questions: (1) is the IS success model vali...

nowadays, due to the competitive conditions of global market, corporations try to outsource their extraneous processes to third-party suppliers. so, selecting a proper supplier play a significant role in organization success. the supplier selection problem can be viewed as a group decision-making problem with multiple criteria. since in previous researches the inter relationship between criteri...

The decision making on selection of improvement solutions was one of the obstacles hampering the success of process improvement. This paper presents the House of Improvement (HOI) model as a guideline to link decision criteria for the prioritisation of improvement solutions. Three phases in the HOI are applied to facilitate selection and to ensure that suitable and value-added solutions are cho...
