Data-driven vertiport siting: A comparative analysis of clustering methods for Urban Air Mobility by Tao Guo, Hao Wu, Shahriar Iqbal Zame, Constantinos Antoniou

“…The inferiority of DBSCAN, OBUAM and MS scenarios reveals that neither concentrating vertiports excessively in urban centers nor distributing them too evenly across the region optimizes transport efficiency. All clustering-based methods offer a practical, data-driven alternative that does not rely on domain expertise or excessive computational resources, making them easily adaptable for real-world UAM planning. …”

Video Spectral Methods and Tools for Monitoring of Controlled Parameters of Forest Fires and Oil Spill Accidents by A. S. Sizikov, Y. V. Belyaev, I. M. Tsykman, A. P. Popkov

“…The results of studies made it possible to increase the accuracy of identification of monitoring objects in emergency zones up to two times.The main provisions of the two developed methods were outlined. The first method was methodology for determination of the controlled parameters of forest fires by means of aviation monitoring, which makes it possible to record the maximum values of the degree of polarization of reflected radiation for coal 30–40 % and for semi-coal 15–20 % in the wavelength range from 0.5 to 0.7 μm. …”

Age- and sex-related changes in the position of the mental foramina and age estimation methods that use these changes by Masataka Kawamoto, Hiroki Kondou, Hiroaki Ichioka, Satoko Kimura, Risa Bandou, Ryota Matsunari, Ting Deng, Hiroshi Ikegaya

“…The results of the single regression analysis showed a positive correlation (r = 0.54) of the distance with age in men and a negative correlation (r=-0.54) in women. The mean coefficient of determination for single regression analysis was 0.26 for both sexes, which was low, making it unsuitable as a stand-alone age estimation index, although it can aid in age estimation.…”

Rumen gas kinetics: a comparative analysis of two in vitro assessment methods for forage evaluation by Nejc VALCL, Andrej LAVRENČIČ

“…Significant differences were observed between the HGT and ANKOM in the specific gas production rate (parameter C), maximum fermentation rate (MFR) and gas produced after 24 h of incubation (Gas24) for each feed group. High coefficients of determination (R2) were calculated between the methods for the gas kinetic parameters MFR, Gas24, total potential gas production (parameter B), decrease in the specific gas production rate (parameter A), moderate R2 for C, and low R2 for time of maximum fermentation rate (TMFR). …”
