Theoretical and experimental research on influencing factors and rules of flow-induced rudder system vibration

Zhongguo Jianchuan Yanjiu, 2017
Flow-induced rudder system vibration has a great influence on the stealthiness of underwater vehicles. In order to study the vibration characteristics of rudder systems, a mathematical model of a binary linear flutter rudder system is built according to ...

Architecting and Industrializing Advanced Production and Manufacturing Systems for Critical Industries

Systems Engineering, EarlyView.
ABSTRACT Advanced production systems play a vital role in modern society. Such systems are developed and industrialized over multiple years and at great expense. The complexities of these systems are exacerbated in the case of metal additive manufacturing, which involves numerous process variables and relies on various auxiliary systems.

immunoHuMiX: A personalizable gut‐on‐chip model for unraveling human microbiome–immune interactions

VIEW, EarlyView.
The study introduces a personalized gut model that brings together human immune cells and intestinal cells to better mimic how the body interacts with microbes. This system successfully maintained both human cells and a 17‐strain probiotic community, showing consistent immune responses across different donors.

Nonlinear Programming-Based Fault-Tolerant Control for X-Rudder AUVs

水下无人系统学报
To fully utilize the fault-tolerant capability of the X-rudder autonomous undersea vehicles (AUVs), a fault-tolerant motion control algorithm for AUVs oriented towards rudder failures was proposed, and it was deployed on a prototype of an X-rudder AUV ...

The Role of Children's Voices and Feedback Mechanisms in Family Justice

Child &Family Social Work, EarlyView.
ABSTRACT When parents separate in Australia and in many other jurisdictions, most settle the parenting arrangements for their children between themselves or with the assistance of mediation or other dispute resolution processes. These processes may or may not take much account of children's views.

Under-actuated USV path following control under multiple constraints

AIP Advances, 2022
The path following control of an under-actuated unmanned surface vehicle (USV) under the constraints of rudder angle, rudder velocity, and rudder response time in the disturbing environment is studied, and a cascaded path following control system based ...

Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...
