Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

An Integrated Numerical and Bollard Pull Evaluation Approach for Early‐Stage Resistance and Thrust Assessment of a Small Craft

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Early‐stage hydrodynamic assessment of slender multihull vessels is challenged by limited geometric maturity, uncertain propulsion integration, and strong sensitivity to operating conditions. Under such constraints, reliance on a single analytical or numerical method may lead to misleading design decisions due to oversimplification or ...

Diagnosis of Urethral Resistance in Men: 70 Years of History

Neurourology and Urodynamics, EarlyView.
ABSTRACT Background and Aims The urethral resistance (UR) is one of the key outcomes of the urodynamic pressure‐flow study (PFS) in men. Combined with a clinical meaningful cut‐off point, urodynamic bladder outflow obstruction (BOO) can be determined. This characterization of BOO provides guidance in the management of lower urinary tract symptoms (LUTS)

Association of Nasal Anatomy, Airflow, and Surgery With Olfactory Outcomes: A State‐of‐the‐Art Review

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Olfactory function is influenced by nasal airflow dynamics and anatomical variations within the nasal cavity. This narrative review evaluates how nasal anatomy and airflow relate to olfactory outcomes, with a particular focus on olfactory changes following functional nasal surgery. Data Sources PubMed.
