We present an empirical method for converting single-point near-infrared J, H, and K measurements of fundamental-mode Cepheids to mean magnitudes, using complete light curves in V or I bands. The algorithm is based on the template light curves in the near-infrared bandpasses. The mean uncertainty of the method is estimated to about 0.03 mag, which is smaller than the uncertainties obtained in o...

In this paper, novel dispersion engineered conformal metamaterial-based leaky-wave antennas (LWA) based on composite right/left-handed (CRLH) concept are being reviewed. As a planar CRLH LWA is conformed on a curved surface, the radiation characteristics of LWA is distorted. The effect of conformation on a CRLH LWA is investigated. A dispersion engineering method is presented to compensate for ...

S U M M A R Y We present a single station method for the determination of Rayleigh wave ellipticity, or Rayleigh wave horizontal to vertical amplitude ratio (H/V) using Frequency Dependent Polarization Analysis (FDPA). This procedure uses singular value decomposition of 3-by-3 spectral covariance matrices over 1-hr time windows to determine properties of the ambient seismic noise field such as ...

In this chapter we study the sedimentation of several thousand circular particles in 2D using the method of distributed Lagrange multipliers for solid-liquid flow. The simulation gives rise to fingering which resembles Rayleigh-Taylor instabilities. The waves have a well defined wavelength and growth rate which can be modeled as a conventional Rayleigh-Taylor instability of heavy fluid above li...

Dissipative nonlinear wave dynamics have been investigated extensively in mode-locked lasers with single transverse-mode, whereas there are few studies related to three-dimensional within lasers. Recently, spatiotemporal mode-locking (STML) was proposed small modal (i.e., transverse-mode) dispersion, which has considered be critical for achieving STML those cavities because the dispersion can e...

Background and Aims: Production of acoustic cavitation by sonication has been recently recommended as a targeted treatment. The experimental results from studies indicate that the activity of cavitation generated by bi- or multi-frequency ultrasound irradiation is higher than that caused by single frequency irradiation. In this study, effects dual (1 MHz and 40 kHz) and single frequency soni...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...
