In this paper, we study a nonlinear double phase problem with variable exponent and critical growth on the boundary. The has in reaction combined effects of Carathéodory perturbation defined only locally term. presence term does not permit to apply results point theory corresponding energy functional. Thus, use appropriate cut-off functions truncation techniques work an auxiliary coercive probl...

We propose a computationally efficient approximation for the double bootstrap bias adjustment factor without using the inner bootstrap loop. The approximation converges in probability to the population bias correction factor. We study the finite sample properties of the approximation in the context of a linear instrumental variable model. In identified versions of the model considered in our Mo...

A novel variable optical attenuator device is proposed and some of the potential application is pointed out. It relies on a double acousto optic modulator set up and allows one to attain dynamic range as high as 60 dB. Such feature steams out of the well known modeling of acousto optic devices, mostly based on the coupled wave analysis. Furthermore, is shown that the proposed device may exhibit...

the paper presents an economical model for double variable acceptance sampling with inspection errors. taguchi cost function is used as acceptance cost while quality specification functions are normal with known variance. an optimization model is developed for double variables acceptance sampling scheme at the presence of inspection errors with either constant or monotone value functions. the m...

A new method of numerical integration is presented here, the variable-step Störmer-Cowell method. The method uses error control to regulate the step size, so larger step sizes can be taken when possible, and is double-integration, so only one evaluation per step is necessary when integrating second-order differential equations. The method is not variable-order, because variable-order algorithms...

A double-talk detector (DTD) is generally used with an acoustic echo canceller (AEC) in pinpointing the region where far-end and near-end signal coexist. This region is called double-talk and during this region AEC usually freezes the adaptation. Decision variable used in DTD has a relatively longer transient time going from double-talk to single-talk than time going in opposite direction. Ther...

We perform a detailed theoretical and empirical comparison of the dual and hidden variable encodings of non-binary constraint satisfaction problems. We identify a simple relationship between the two encodings by showing how we can translate between the two by composing or decomposing relations. This translation suggests that we will tend to achieve more pruning in the dual than in the hidden va...
