NOISE AND SIGNAL FOR RESCUERS RADAR
Радиофизика и электроника, 2017 The adequate models of information signals and noise have been developed to solve the actual problem of the synthesis of hardware and software for operative detection of affected peop-le in man-made or natural disasters. It is shown that at low frequencies, where are placed the spectral components of the information signal generated by breathing and ...

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology
InfoScience, EarlyView.Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored

Tropical Cyclone Rainfall Spatial Asymmetries in the Lesser Antilles
International Journal of Climatology, EarlyView.Rainfall is not proportional to the Saffir‐Simpson wind‐based categories. Lower category tropical cyclones (TS, H1, H2 and H3) can generate more intense rainfall than H4 and H5. Rainfall is asymmetric; as a tropical cyclone intensifies or weakens, the location of peak rainfall shifts.

Journal of Raman Spectroscopy, EarlyView.We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Knowledge and Process Management, EarlyView.ABSTRACT This study examines how business process management (BPM) maturity shapes digital transformation in a large financial institution operating in a highly regulated, emerging‐economy context. Drawing on a qualitative single case study, the research applies Rosemann and De Bruin's BPM Maturity Model to analyse how different maturity dimensions ...

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator
Laser &Photonics Reviews, EarlyView.This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Non‐Uniform Programmable Photonic Waveguide Meshes
Laser &Photonics Reviews, EarlyView.Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

Laser &Photonics Reviews, EarlyView.An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.
