Spectrum Aliasing Does Occur Only in Case of Non-ideal Signal Sampling [PDF]
International Journal of Electronics and Telecommunications, 2021 In this paper, it has been shown that the spectrum aliasing and folding effects occur only in the case of non-ideal signal sampling. When the duration of the signal sampling is equal to zero, these effects do not occur at all.

Ecosystem scale acoustic sensing reveals humpback whale behavior synchronous with herring spawning processes and re-evaluation finds no effect of sonar on humpback song occurrence in the Gulf of Maine in fall 2006. [PDF]
PLoS One, 2014 We show that humpback-whale vocalization behavior is synchronous with peak annual Atlantic herring spawning processes in the Gulf of Maine. With a passive, wide-aperture, densely-sampled, coherent hydrophone array towed north of Georges Bank in a Fall ...

Another Proof of Ambiguity of the Formula Describing Aliasing and Folding Effects in Spectrum of Sampled Signal [PDF]
International Journal of Electronics and Telecommunications, 2022 In this paper, a new proof of ambiguity of the formula describing the aliasing and folding effects in spectra of sampled signals is presented. It uses the model of non-ideal sampling operation published by Vetterli et al.

Spectrum Aliasing Does not Occur in Case of Ideal Signal Sampling [PDF]
International Journal of Electronics and Telecommunications, 2021 A new model of ideal signal sampling operation is developed in this paper. This model does not use the Dirac comb in an analytical description of sampled signals in the continuous time domain. Instead, it utilizes functions of a continuous time variable,

The State and Trend of China’s Low-Carbon Development
China's Long-Term Low-Carbon Development Strategies and Pathways, 2021 The Paris Agreement established the long-term temperature goal to hold global average temperature rise to well below 2°C above pre-industrial levels and to pursue efforts to limit the global temperature rise to 1.5°C.Basedon a “bottom-up” approach ...

Time-resolved X-Shooter spectra and RXTE light curves of the ultra-compact X-ray binary candidate 4U 0614+091 [PDF]
, 2012 In this paper we present X-Shooter time resolved spectroscopy and RXTE PCA light curves of the ultra-compact X-ray binary candidate 4U 0614+091. The X-Shooter data are compared to the GMOS data analyzed previously by Nelemans et al. (2004).

Stellar Model Analysis of the Oscillation Spectrum of eta Bootis Obtained from MOST [PDF]
, 2005 Eight consecutive low-frequency radial p-modes are identified in the G0 IV star eta Bootis based on 27 days of ultraprecise rapid photometry obtained by the MOST (Microvariability & Oscillations of Stars) satellite. The MOST data extend smoothly to lower

A New Small-Amplitude Variable Hot DQ White Dwarf [PDF]
, 2010 We present the discovery of photometric variations in the carbon-dominated atmosphere (hot DQ) white dwarf star SDSS J133710.19-002643.6. We find evidence for two low-amplitude, harmonically-related periodicities at 169 s and 339 s, making it the fastest
