A class of even order neutral equations with continuous distributed deviating arguments [x(t) + ∫ d c p(t, η)x[r(t, η)]dτ(η)] + ∫ b a q(t, ξ)f(x[g(t, ξ)])dσ(ξ) = 0 is considered and its oscillation theorems are discussed. These theorems are of higher degree of generality and deal with the cases which are not covered by the known criteria. Particularly, these criteria extend and unify a number o...

By using the functions of the form H(t, s) and a generalized Riccati technique, we establish new Kamenev-type and interval oscillation criteria for second-order nonlinear dynamic equations on time scales of the form ( p(t)x(t) )∆ + f(t, x(σ(t))) = 0. The obtained interval oscillation criteria can be applied to equations with forcing term. Two examples are included to show the significance of th...

In this paper, we introduce a statistically efficient method f o r detecting ellipses in a n image. Given a set of digital arc segments, we introduce geometric criteria t o select possible pairs of arc segments belonging to the same ellipse. T h e selected arc pairs are subsequently validated or rejected based o n certain statistical criteria via hypothesis testing. The advantages of our techni...

In this article, we establish some new criteria for the oscillation of fourth order nonlinear delay differential equations of the form x(t) + p(t)x(t) + q(t)f(x(g(t))) = 0 provided that the second order equation z(t) + p(t)z(t) = 0 is nonoscillatiory or oscillatory. This equation with g(t) = t is considered in [8] and some oscillation criteria for this equation via certain energy functions are ...

This paper deals with multi-criteria decision making (MCDM) problems with multiple priorities, in which priority weights associated with the lower priority criteria are related to the satisfactions of the higher priority criteria. To do so, we first propose a prioritized weighted aggregation operator based on ordered weighted averaging (OWA) operator and triangular norms (t-norms). In order to ...
