Pencil graphite electrodes are a simple, disposable, and low-cost alternative to screen-printed electrodes. In terms of stability sensitivity, pencil often outperform conventional carbon ones. This paper discusses emphasizes the superior properties polymer (pPeGEs), which can be exploited in electrochemical analysis molecules, such as chlorides, whose signals missing on common The chemical stru...

Several spaceborne scatterometer missions have been successfully flown in the past decade. In addition to the primary mission of measuring ocean surface wind speed and direction, these measurements have proven useful in global scale climate studies of land and ice phenomena as well. A key shortcoming of the scatterometer in these measurements has been the rather coarse spatial resolution availa...

In this paper we review the derivation of implicit equations for non-degenerate quadric patches in rational Bézier triangular form. These are the case of Steiner surfaces of degree two. We derive the bilinear forms for such quadrics in a coordinate-free fashion in terms of their control net and their list of weights in a suitable form. Our construction relies on projective geometry and is groun...

Several recent methods used to analyze asymptotic stability of delay-differential equations (DDEs) involve determining the eigenvalues of a matrix, a matrix pencil or a matrix polynomial constructed by Kronecker products. Despite some similarities between the different types of these so-calledmatrix pencil methods, the general ideas used as well as the proofs differ considerably. Moreover, the ...
