the present study is an attempt to investigate some features of radial basis functions (rbfs) approximation methods related to variational problems. thereby authors applied some properties of rbfs to develop a direct method which reduces constrained variational problem to a static optimization problem. to assess the applicability and effectiveness of the method, some examples are examined. dyna...

We introduce an implicit method for nding a common element of the set of solutions of systems of equilibrium problems and the set of common xed points of a sequence of nonexpansive mappings and a representation of nonexpansive mappings. Then we prove the strong convergence of the proposed implicit schemes to the unique solution of a variational inequality, which is the optimality condition for ...

With the aim of improving rapidity and accuracy quadrotor UAV positional trajectory tracking, this paper proposes a fuzzy automatic disturbance rejection control based on improved whale optimization algorithm (IWOA-Fuzzy-ADRC). (1) To address problems low slow convergence traditional algorithm, combination logistic chaos mapping skew tent is applied to improve diversity initial population. (2) ...

The paper presents a revision of the contemporary reductionistic demand theory, replacing studying object, i.e. an individual, with fuzzy collection market buyers, regarded as “statistical ensemble consumers”. new holistic theory formally retains neoclassical reconsidering utility function collective one. A nonparametric verification method is presented, which uses economic (Konus) and formula ...

It’s shown that a number of variational problems can be cast as finding the maxinf-points (or minsup-points) of bivariate functions, coveniently abbreviated to bifunctions. These variational problems include: linear and nonlinear complementarity problems, fixed points, variational inequalities, inclusions, non-cooperative games, Walras and Nash equilibrium problems. One can then appeal to the t...

The clearance between the main roller and cylinder cam has an important impact on operational status of bolt. In order to achieve recoil mechanism, a bolt model was built studied. leading dynamic group were analyzed. Positive stress friction force change quickly high-speed group, influencing multiple aspects. When suddenly rotates or reverses in several short intervals, assembling massive curve...

The applications of symmetry groups to problems arising in the calculus of variations have their origins in the late papers of Lie, e.g., [34], which introduced the subject of “integral invariants”. Lie showed how the symmetry group of a variational problem can be readily computed based on an adaptation of the infinitesimal method used to compute symmetry groups of differential equations. Moreo...
