Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Robust autopilot of the pitch channel of unmanned aircraft vehicles
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 Automatic pitch control system of unmanned aircraft vehicles (UAVs) with different aerodynamic configuration and airframe construction is reflected here. Robust autopilot scheme is proposed for such control system. While adjusting the parameters of UAV’s

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

UAV‐Based Precision Seed Dropping for Automated Reforestation
Journal of Field Robotics, EarlyView.ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Symbolic Interaction, EarlyView.What happens when stories refuse coherence? This article examines ambiguous loss among mothers of combat soldiers, focusing on how prolonged waiting and uncertainty infiltrate everyday life, eroding sensemaking. Drawing on ethnographic interviews, it explores how mothers experience the contraction of time and space—manifested in suspended routines ...

What is (de)politicization and what is wrong with it?
American Journal of Political Science, EarlyView.Abstract This article attempts to clarify the meaning of (de)politicization. Politicization sometimes refers to the inappropriate intrusion of partisan loyalties in nonpolitical social domains (affective politicization). Politicization can also constitute an ideal of civic agency and energy (contestatory politicization).
