It has been argued that most of corpus linguistics involves one of four fundamental methods: frequency lists, dispersion, collocation, and concordancing. All these presuppose (if only implicitly) the definition of a unit: the element whose frequency in a

Transmitting-absorbing material based on resistive metasurface
We theoretically and experimentally studied a transmitting-absorbing material that had transmission window within the absorption band. The material had a sandwich structure comprised of a resistive metasurface, a dielectric substrate and a metallic slot ...

In-Band Radar Cross Section Reduction of Slot Array Antenna
A slot array antenna is proposed for both in-band and out-of-band radar cross section (RCS) reduction. The presented slot array antenna is covered by the superstrate consisting of a polarization rotation reflective surface (PRRS).

Analytical Model of a Single Link of Elastic Optical Networks
This article discusses and evaluates a model of resources to which multiservice traffic is offered. The initial assumption for the model is that calls of particular traffic classes are always serviced in neighboring allocation units of the resources ...

Axially Uniform Magnetic Field-Modulation Excitation for Electron Paramagnetic Resonance in Rectangular and Cylindrical Cavities by Slot Cutting [PDF]
In continuous-wave (CW) Electron Paramagnetic Resonance (EPR) a low-frequency time-harmonic magnetic field, called field modulation, is applied parallel to the static magnetic field and incident on the sample.

A Multi-Service Model of Resources With the Neighboring Choice of Allocation Units
This article discusses a discretized model of resources to which a mixture of multi-service traffic streams is offered. In the model the connections of individual traffic classes that require a large number of allocation units are always executed using ...

Study and Design of a Diferentially Fed Tapered Slot Antenna Array [PDF]
The results of a parametric study and design of an ultrawideband dual-polarized array of differentially-fed tapered slot antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential ...

A Novel Densely Packed 4 × 4 MIMO Antenna Design for UWB Wireless Applications
In this article, a compact 4-port UWB (Ultra-Wide Band) MIMO (Multiple Input Multiple Output) antenna is proposed. A low profile FR-4 substrate is used as a dielectric material with the dimensions of 58 × 58 mm2 (0.52λ × 0.52λ) at 2.8 GHz and a standard ...
