Abstract Organic light-emitting diode (OLED) fibers with favorable electroluminescence properties and interconnectable pixel configurations have represented the potential for wearable electronic textile displays. Nevertheless, current technology of OLED fiber-based displays still leaves to be desired due several challenges, including limited emission area lack encapsulation systems. Here we pre...

We give a simple condition on a matrix for which if the exponential matrix is diagonal, lower or upper triangular, then so is . It is also shown that for diagonalizable and any matrix , and commute if and only if and commute. These results are useful in problems in which knowledge about has to be extracted from structural information about its exponential, such as in large-scale sampled-data sy...

We study a decision problem that emerges from the area of spatial reasoning, but that is also of interest to the area of computational algebraic geometry. This decision problem concerns the use of constraint calculi in qualitative spatial reasoning. One such qualitative calculus describes polylines in the plane by means of their double-cross matrix. In such a matrix, the relative position (or o...

this paper analyzes a linear system of equations when the righthandside is a fuzzy vector and the coefficient matrix is a crisp m-matrix. thefuzzy linear system (fls) is converted to the equivalent crisp system withcoefficient matrix of dimension 2n × 2n. however, solving this crisp system isdifficult for large n because of dimensionality problems . it is shown that thisdifficulty may be avoide...

In the part of radiolocation focused on one target tracking we can find for example active radar and passive surveillance systems but we cannot find any representative of passive radiolocation area. Therefore this paper is focused on the conceptual design and practical solution of passive radar for one target tracking. The scanning of the area of interest is ensured by an antenna system with a ...

BACKGROUND AND PURPOSE Acceleration of intra-aneurysmal clot organization and fibrosis may be a solution to preventing aneurysm recanalization after endovascular treatment. The purpose of this study was to evaluate the short-term efficacy and long-term safety of the new Matrix coil system. METHODS Matrix coils consist of thin platinum coils covered with a bioabsorbable, polymeric material (po...
