We conjecture that meanders are governed by the gravitational version of a c = −4 two-dimensional conformal field theory, allowing for exact predictions for the meander configuration exponent α = √ 29( √ 29 + √ 5)/12, and the semi-meander exponent ᾱ = 1+ √ 11( √ 29+ √ 5)/24. This result follows from an interpretation of meanders as pairs of fully packed loops on a random surface, described by t...

Slotted Meander-Line Resonator (SMLR) is implemented by creating defect in the microstrip structure. This resonator is designed to block the surface current at the resonant frequency of the two patch antennas coupled along H-plane operating at 3.6 GHz. The proposed configuration provides an improvement in isolation by 10 dB (measured value) with a reduced edge-to-edge spacing of 7 mm (λ0/9). Th...

SkyCross' state-of-the-art antennas are smaller and can be embedded directly within the handset. In addition, they feature better gain and improved efficiency, resulting in longer battery life than other handsets currently available on the market today. Furthermore, MLA technology allows engineers to design ultra broadband antennas capable of operating at multiple frequencies and in a variety o...

Comparison of historic channel migration rates, modern planform conditions, and overall sediment, wood, and flow conditions and interactions for the Quinault River and Queets River in the western Olympic Peninsula, Washington, reveals decadalto century-scale interactions between gravel-bed channels and forested flood plains in temperate maritime environments. The downstream alluvial portions of...

Abstract In the present study, meandering behavior of Barak River (Cachar), Assam was traced. Flow path length, meander neck sinuosity index, and river migration were determined segment-by-segment to demonstrate morphological changes. Decadal land-use land cover (LULC) maps also prepared at section scale using Landsat data (1990–2020) validated with Kappa coefficient characterize changes along ...

This paper presents a printed dual band monopole antenna working below 250 MHz using meander line and an added stub. Meander approach is used to reduce the size of low frequency monopole. The proposed fed by microstrip on FR-4 substrate with overall 290 x 83 mm 2 . stub tuned operation at 114 221 measured reflection coefficient -19 dB both bands. has omni-directional characteristics efficiency ...

This is the second of three papers on the geometric and combinatorial characterization of global Sturm attractors which consist of a single closed 3-ball. The underlying scalar PDE is parabolic, ut = uxx + f(x, u, ux) , on the unit interval 0 < x < 1 with Neumann boundary conditions. Equilibria are assumed to be hyperbolic. Geometrically, we study the resulting Thom-Smale dynamic complex with c...
