On the approximation of measurable linear functionals

Every Gaussian Radon measure (nonsymmetric) has the Riesz property. On R^∞, a shift μ₀ 1 σ_b of the law μ₀ of the Bernoulli sequence has the Riesz property iff $\text{b ? l}{}^2\text{or}\text{b ?}\text{R}{}_0{}^{\mathrm{\infty }}$.

Distribution-independent properties of the convex hull of random points

Denote byV _n ^(d) the expected volume of the convex hull ofn points chosen independently according to a given probability measure in Euclideand-spaceE ^d. Ifd=2 ord=3 and is the measure corresponding to the uniform distribution on a convex body inE ^d, Affentranger and Badertscher derived that

Free vibration characteristics of a functionally graded beam by finite element method

This paper presents the dynamic characteristics of functionally graded beam with material graduation in axially or transversally through the thickness based on the power law. The present model is more effective for replacing the non-uniform geometrical beam with axially or transversally uniform geometrical graded beam. The system of equations of motion is derived by using the principle of virtual work under the assumptions of the Euler–Bernoulli beam theory. The finite element method is employed to discretize the model and obtain a numerical approximation of the motion equation. The model has been verified with the previously published works and found a good agreement with them. Numerical results are presented in both tabular and graphical forms to figure out the effects of different material distribution, slenderness ratios, and boundary conditions on the dynamic characteristics of the beam. The above mention effects play very important role on the dynamic behavior of the beam.     

Expression for restricted partition function through Bernoulli polynomials

Explicit expressions for restricted partition function W(s,d ^m ) and its quasiperiodic components W _j (s,d ^m ) (called Sylvester waves) for a set of positive integers d ^m ={d ₁,d ₂,…,d _m } are derived. The formulas are represented in a form of a finite sum over Bernoulli polynomials of higher order with periodic coefficients.      

On weighted q-Daehee polynomials with their applications

In this paper, we first consider a generalization of Kim’s $p$-adic $q$-integral on ${\mathbb{Z}}_p$ including parameters $\alpha$ and $\beta$. By using this integral, we introduce the $q$-Daehee polynomials and numbers with weight $\left(\alpha ,\beta \right)$. Then, we obtain some interesting relationships and identities for these numbers and polynomials. We also derive some correlations among $q$-Daehee polynomials with weight $\left(\alpha ,\beta \right)$, $q$-Bernoulli polynomials with weight $\left(\alpha ,\beta \right)$ and Stirling numbers of second kind.     

Nonnegative Solutions to Systems with Symmetric Circulant Matrix

For a system with symmetric circulant matrix, conditions on the right-hand side vector which ensure the positivity of the solution to the system are found. As an application of the results obtained, the problem of positive spline interpolation of positive functions on uniform grids is studied.     

Dynamic feedback control and exponential stabilization of a compound system

We studied the exponential stabilization problem of a compounded system composed of a flow equation and an Euler–Bernoulli beam, which is equivalent to a cantilever Euler–Bernoulli beam with a delay controller. We designed a dynamic feedback controller that stabilizes exponentially the system provided that the eigenvalues of the free system are not the zeros of controller. In this paper we described the design detail of the dynamic feedback controller and proved its stabilization property.
