This paper present simulation-based results on the impact of transmitter (Tx) position and orientation uncertainty accuracy visible light positioning (VLP) system based received signal strength (RSS). There are several constraining factors for RSS-based algorithms, particularly due to multipath channel characteristics set-up uncertainties. The Tx uncertainties error performance is studied, assu...

Temperature inversions in mainland France are computed using a network of 859 sampling sites spread as evenly possible across the country. Each site comprises high station located within 30 km low with which it is paired. We use daily minimum (tn) and maximum (tx) temperatures from Météo-France weather stations over 10 years (2008–2017). The time variations three inversion characteristics (freq...

Abstract Between 2015 and 2020 a study was conducted on the diversity of ruderal vegetation Stellarietea mediae class territory Ukraine. It discovered that this consists 48 associations from 12 alliances 5 orders ( Aperetalia spicae-venti , Atriplici-Chenopodietalia albi Eragrostietalia Papaveretalia rhoeadis Sisymbrietalia sophiae ). Based results ordination analysis it found distribution annu...

This paper presents a transmitter (TX) and receiver (RX) with bowtie-antenna silicon lens for gas spectroscopy at 222-270 GHz, which are fabricated in IHP’s 0.13 μm SiGe BiCMOS technology. The TX RX use two integrated local oscillators 222 – 256 GHz 250 270 switched dual-band operation. Due to its directivity of about 27 dBi, the single enables an EIRP 25 dBm TX, therefore considerably higher 2...

Work has continued on the "analysis-by-synthesis" programs (1, 2) for the TX-0 computer, with an emphasis on gaining greater precision in the matching of vowel and consonant spectra, greater ease in manipulating test spectra, and a better understanding of various error criteria. Collaterally with the automatic resolution of spectra leading to the development of speech-recognition systems, atten...
