Dynamic Modeling of Autonomous Underwater Vehicle for Underwater Surveillance and Parameter Tuning with Experiments

Journal of Ocean Engineering and Technology, 2015
This paper presents the dynamic model of an AUV called HW200 for underwater surveillance. The mathematical model of HW200 is briefly introduced, considering its shape. The maneuvering coefficients were initially estimated using empirical formulas and a database of vehicles with similar shapes.

Clinicopathological Features of Superficial Non‐Ampullary Duodenal Epithelial Tumors Involving Brunner's Glands

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background and Aims Although Brunner's glands (BGs), located in the submucosa of the duodenum, may be involved by tumor cells of superficial non‐ampullary duodenal epithelial tumors (SNADETs), the detailed incidence and histopathological features have not yet been analyzed. This study aimed to clarify the histopathological relationship between

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

Journal of Field Robotics, Volume 43, Issue 2, Page 561-577, March 2026.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Building Local Resilience Potential on a Day‐to‐Day Basis: The Influence of Stakeholder Dynamics and Contextual Factors

Journal of Contingencies and Crisis Management, Volume 34, Issue 1, March 2026.
ABSTRACT The aim of this study is to clarify how and under what conditions an area builds (or fails to build) its resilience potential on a day‐to‐day basis. In this way, it contributes to a better understanding of the influence of the antecedents of resilience (e.g., undesirable events, capacity of stakeholders).
