We answer a question raised by P. Brass on the number of maximally repeated sub-patterns in a set of n points in $\mathbb{R}^{d}$. We show that is number, which was conjectured to be polynomial, is in fact $\Theta(2^{\frac{n}{2}})$ in the worst case, regardless of the dimension d.

We establish fixed point and multidimensional fixed point results satisfying generalized (𝜓, 𝜃, 𝜑)-contraction on partially ordered non-Archimedean fuzzy metric spaces. By using this result we obtain the solution for periodic boundary value problems and give an example to show the degree of validity of our hypothesis. Our results generalize, extend and modify several well-known results in the literature.

In this paper, we study more general version of the paper [J. H. Lee, I. S. Kong, H. S. Kim and J. U. Jung, Generalized int-soft subsemigroups, Ann. Fuzzy Math. Inform. 8(6) (2014) 869-887]. We introduce the notion of int-soft semigroup with two thresholds ${\varepsilon}$ and ${\delta}$ (briefly, (${\varepsilon}$, ${\delta}$)-int-soft semigroup) of a semigroup S, and investigate several related properties.

This paper considers the likelihood ratio test statistic based on nonlinear regression quantiles estimators in order to test of hypothesis about the regression parameter $\theta_o$ and derives asymptotic distribution of proposed test statistic under the null hypothesis and a sequence of local alternative hypothesis. The paper also investigates asymptotic relative efficiency of the proposed test to the test based on the least squares estimators or the least absolute deviation estimators and gives some examples to illustrate the application of the main result.

Contrary to the popular view that dative is idiosyncratic to verbs or particular theta roles, the distribution of dative is predictable from the distribution of other cases like nominative, accusative, instrumental, etc. That is, dative behaves like an unmarked or elsewhere choice for Non-Actor/Non-Patient (＝NANP) roles. This paper develops a theory of semantic structural case under the framework of conceptual semantics (Jackendoff 1983, 1990, 1997, 2002). In my proposed analysis, dative is structurally mapped onto NANP entities in the conceptual structure. Important consequences about other peripheral roles are discussed in section 5.

In this paper, we introduce the concept of fuzzy (r, s)-semi-irresolute mappings on intuitionistic fuzzy topological spaces in Sostak's sense, which is a generalization of the concept of fuzzy semi-irresolute mappings introduced by S. Malakar. The characterizations for the fuzzy (r, s)-semi-irresolute mappings are obtained by terms of semi-interior, semi-${\theta}$-interior, semi-clopen, and regular semi-open.

Lipschitz stability and Lipschitz ø$_{o}$ - equistability of the functional differential equation x'= B(x)f(t, x, $x_{t}$), $x_{to}$ =$\theta$$_{o}$ are discussed. Sufficient conditions are given using the comparison with the corresponding scalar equation.ion.n.

The experimental and numerical results of buckling loads for symmetrically laminated composite plates are compared. Boundary conditions are all fixed supports. Experiments were conducted for plates with fiber angles $\theta$=30$^{\circ}$, 45$^{\circ}$, 60$^{\circ}$ and aspect ratios a/b=0.8. Experimental results were obtained from load-deflection curves. Numerical methods were presented to evaluate buckling loads, using structural analysis results from ANSYS.

We study the Bayes estimation procedure of ${\theta}=P_r$=(Y < X) when the experiment is terminated before all of the items on the test have failed and the failed items are partially replaced. Comparisons with the M.L.E., M.V.U.E. and Bayes estimator are made through Monte Carlo simulation.

This study is to applicate IPC girder at curved bridge. This study introduces the variable(radius, $d_{ci}$, $d_{co}$, etc..) used in design IPC curved bridge. And this presents the possible radius in simple bridge and continuous bridge. For example, simple bridge that have span length is 30m, minimum possible radius is 300m. In continuous bridge, girders are arranged by sloped in $\theta$. So in this case, the bridge is under consideration that horizontality pressure in bridge pier.
