An optimum design of on-bottom stability of offshore pipelines on soft clay by Su Young Yu, Han Suk Choi, Seung Keon Lee, Chang Ho Do, Do Kyun Kim

“…Thus, a new procedure of the on-bottom stability analysis was established considering dynamic effects of pipeline installation and pipe-soil interaction at touchdown point (TDP). This analysis procedure is composed of three steps: global pipeline installation analysis, local analysis at TDP, modified on-bottom stability analysis using DNV-RP-F109. …”

Contact Model Fusion for Event-Based Locomotion in Unstructured Terrains by Wensing, Patrick M., Bledt, Gerardo, Ingersoll, Samuel, Kim, Sangbae

“…This paper introduces an approach to probabilistically fuse contact models, managing uncertainty in terrain geometry, dynamic modeling, and kinematics to improve the robustness of contact initiation at touchdown. A discrete-time extension of the generalized-momentum disturbance observer is presented to increase the accuracy of proprioceptive force control estimates. …”

Assessing the impact of the slopes on runway drainage capacity based on wheel/path surface adhesion conditions by Misagh Ketabdari, Emanuele Toraldo, Maurizio Crispino

“…A risk analysis framework is developed to study the effects of longitudinal and transverse slopes on the aircraft braking distance in wet runway conditions and their influences on the probability of landing overrun accidents.This framework is operating under various water-film thicknesses, Maximum Landing Weights (MLW), and touchdown speed probability distributions for an acceptable range of longitudinal/transverse slopes and pavement texture depths.A simulator code is developed that initially computes the existing water-film thickness, as the result of intense precipitation,under aircraft main gear (depend on aircraft category) and then applies this variable as one of the main inputs to the aircraft braking distance computation. …”

Birds land reliably on complex surfaces by adapting their foot-surface interactions upon contact by William RT Roderick, Diana D Chin, Mark R Cutkosky, David Lentink

“…Here, we show how Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot, toe, and claw kinematics become surface-specific upon touchdown.

Longitudinal automatic carrier-landing control law rejecting disturbances and coupling based on adaptive dynamic inversion by Lipeng Wang, Zhi Zhang, Qidan Zhu, Zixia Wen

“…The longitudinal automatic carrier landing system (ACLS) control law is designed based on nonlinear dynamic inversion (NDI), which can reject air wake, decouple lateral states, and track the dynamic desired touchdown point (DTP). First of all, the nonlinear landing model of F/A−18 aircraft in the final approach is established, in which the parameters of the aerodynamic, control surfaces, and limited states are acquired. …”
