Evanescent mode substrate integrated waveguide (SIW) is one of the promising technologies for design of light-weight low-cost microwave components. Traditional realization methods used in the standard evanescent waveguide technology are often not directly applicable to SIW due to dielectric filling and small height of the waveguide. In this work, one of the realization methods of evanescent mod...

A spatial model of legislative roll call votes is used to examine the debate surrounding the decision to build a canal across Pennsylvania in 1826. The model reveals a sharp polarization between the English and German-speaking regions of the state, with marked splits over the establishment and funding of the Pennsylvania Canal and other fiscal issues. Representatives from the German-speaking re...

SUMMARY Front-end modules in current cochlear implant devices make use of parallel banks of independent bandpass filters. Compared to the earlier front-end modules implementing formant extraction, filter banks dissipate less power and have superior performance. To further improve the performance of such front-end modules, we propose a front-end module, which consists of a cascade of adaptive se...

Winding is an integral operation in almost every roll to roll system. A center-wound roll is one of the suitable and general schemes in a winding mechanism. In general, the quality of wound roll is known to be related to the lateral displacement error and starring defect of a wound roll. Especially, a telescoping within a center-wound roll can cause damages such as misalignment between layers, ...

me urgently into his bedroom, where I found him deeply cyanosed and making ineffectual respiratory efforts. Some older visiting children had given him a "gob stopper." With thoughts racing through my mind of where in the house would I find a knife sharp enough to attempt emergency tracheostomy, I turned him upside down over my knee and banged his back with the side of my fist several times. Nev...

In this paper, a compact ultra-wideband bandpass filter using a back to back Coplanar Waveguide (CPW)-to-microstrip transition structure is proposed. Compared with traditional ultrawideband bandpass filters using hybrid structures, the proposed filter has a sharper selectivity because of two transmission zeros located at the lower and upper edges of the passband, respectively, generated by a mo...

The paper introduces an operation on a binary tree, called binary tree roll, or roll of a binary tree. Two versions of the binary tree roll, counterclockwise and clockwise, are presented. The operations are mathematically defined and graphically presented. It is explained how the binary tree roll actually coincides with the process of turning the entire tree 90 degrees counterclockwise or clock...
