Optimal trajectory planning of a small UAV using solar energy and wind energy by Jie Chen, Zhiwei Shi, Xi Geng, Qijie Sun, Quanbing Sun, Zhenquan Yin

“…The simulation results show that under the flight background of tmission = 6:00 (summer sunrise) and β = 0.125 s−1 (wind gradient of the wind shear), the optimized O-type trajectory decreased the energy consumption power by 39.86% and increased the solar energy acquisition power by 86.34% compared to the CACV trajectory. …”

Using a photochemical model for the validation of NO₂ satellite measurements at different solar zenith angles by A. Bracher, M. Sinnhuber, A. Rozanov, J. P. Burrows

“…As the HALOE and SAGE II measurements are performed during local sunrise or sunset and because NO₂ has a significant diurnal variability, the NO₂ profiles derived from HALOE and SAGE II have been transformed to those predicted for the solar zenith angles of the SCIAMACHY measurement by using a 1-dimensional photochemical model. …”

Celestial polarization patterns sufficient for Viking navigation with the naked eye: detectability of Haidinger's brushes on the sky versus meteorological conditions by Gábor Horváth, Péter Takács, Balázs Kretzer, Szilvia Szilasi, Dénes Száz, Alexandra Farkas, András Barta

“…Consequently, the sky-polarimetric Viking navigation based on Haidinger's brushes is most useful after sunset and prior to sunrise, when the sun is not visible and large sky regions are bright, clear and polarized enough for perception of Haidinger's brushes.…”

Potential Effects of Permanent Daylight Savings Time on Daylight Exposure and Risk during Commute Times across United States Cities in 2023–2024 Using a Biomathematical Model of Fa... by Jaime K. Devine, Jake Choynowski, Steven R. Hursh

“…Waketimes occurred before sunrise 63 ± 41% percent of the time under DST compared with CTA (42 ± 37%) or ST (33 ± 38%; F(_2,74) = 76.37; <i>p</i> < 0.001). …”

On the reversibility of transitions between closed and open cellular convection by G. Feingold, I. Koren, T. Yamaguchi, J. Kazil

“…Recovery to the closed-cell state is slower when radiative cooling is inefficient such as in the presence of free tropospheric clouds or after sunrise, when it is hampered by the absorption of shortwave radiation. …”

Automated extraction of weight, height, and obesity in electronic medical records are highly valid by Namneet Sandhu, Alexander Krusina, Hude Quan, Robin Walker, Elliot A. Martin, Cathy A. Eastwood, Danielle A. Southern

“…Methods In this cross‐sectional study, 1904 inpatient charts randomly selected in three hospitals in Calgary, Canada between January and June 2015 were reviewed and linked with AllScripts Sunrise Clinical Manager EMRs. A rule‐based algorithm was created which looks for patients' height and weight values recorded in EMRs. …”

A Method of Generating Real-Time Natural Light Color Temperature Cycle for Circadian Lighting Service by Seung-Taek Oh, Deog-Hyeon Ga, Jae-Hyun Lim

“…However, lighting technology that provides the real-time color temperature of natural light could not be realized since it is challenging to select a color temperature cycle zone due to abrupt color temperature changes at sunrise and sunset. Such drastic shifts cause an irregular measurement of color temperature over time due to general weather or atmospheric conditions. …”

Seasonal and Diurnal Variations in Cloud-Top Phase over the Western North Pacific during 2017–2019 by Xiaoyong Zhuge, Xiaolei Zou, Xin Li, Fei Tang, Bin Yao, Lu Yu

“…The occurrences of continental water clouds peak at noon in summer but early morning (around sunrise) in winter. An increase in the frequency of continental summer water clouds around noon is found to be associated with variations in both the cloud-top elevation of already-existing water clouds and new formations of boundary-layer clouds.…”

The influence of day/night cycles on biomass yield and composition of Neochloris oleoabundans by Lenneke de Winter, Iago Teles Dominguez Cabanelas, Dirk E. Martens, René H. Wijffels, Maria J. Barbosa

“…Day/night cycles were provided in a ‘block’ (continuous light intensity during the light period) and in a ‘sine’ (using a sine function to simulate light intensities from sunrise to sunset). There were no differences in biomass yield or composition between these two ways of providing light (in a ‘block’ or in a ‘sine’). …”

Regional Spatiotemporal Statistical Database of Evaporation Ducts Over the South China Sea For Future Long-Range Radio Application by Cheng Yang, Yafei Shi, Jian Wang, Feng Feng

“…First, the overall evaporation duct height (EDH) in the central SCS varies periodically and remains intense throughout the day, decreasing only just before sunrise during 04:00&#x2013;08:00. Moreover, a 20.0 m high channel appears at the &#x201C;Golden edge&#x201D; in the northern coastal area, which can expand as far as 300 km from the coast during May&#x2013;July. …”

“…A busca de técnicas que ampliem o período de conservação e reduzam as perdas pós-colheita é desejável. Mamões 'Sunrise Solo' foram colhidos em dois estádios de maturação (verde e maduro) e tratados com o antagonista competitivo do etileno 1-metilciclopropeno (1-MCP) nas concentrações de 0, 30, 90 e 270 nL L-1, durante 12 horas a 20ºC. …”
