Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

From critique to catalyst: How academic entrepreneurs transform negative feedback into pivots and performance

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary This study examines how academic entrepreneurs refine business ideas in response to external critique and how these responses relate to performance. We develop a framework that links feedback (critique), business‐idea changes (pivots), and performance, and test it using detailed data on external stakeholder feedback, changes ...

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion

SmartBot, EarlyView.
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

Inertial Navigation System

2012
An inertial navigation system is an autonomous system that provides information about position, velocity and attitude based on the measurements by inertial sensors and applying the dead reckoning (DR) principle. DR is the determination of the vehicle’s current position from knowledge of its previous position and the sensors measuring accelerations and ...

Inertial navigation system for bladder endoscopy

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
The usage of video endoscopes in cystoscopic interventions of the urinary bladder impedes an intuitive navigation. Although image-based solutions such as panorama images can provide extended views of the surgical field, a real-time 3-D navigation is not supported.

Integrated Inertial Reference - Inertial Navigation System

Journal of Aircraft, 1976
The value of Inertial Navigation Systems (INS) is reduced for long time-duration flights because uncertainties produce increased position errors with time. A reduction in this position error buildup is obtained from a mechanization concept described in this .paper.

STATISTICAL ESTIMATION IN INERTIAL NAVIGATION SYSTEMS

Guidance and Control Conference, 1966
Although navigation systems have generally been developed by solving exactly the dynamic equations of motion, in reality the navigation problem is a statistical one since there are unpredictable errors in the measurements. The advent of very powerful navigation computers makes it possible by using statistical filtering techniques to retrieve more of ...

Inertial Navigation System Modeling

2012
Modeling requires representing real world phenomena by mathematical language. To keep the problem tractable the goal is not to produce the most comprehensive descriptive model but to produce the simplest possible model which incorporates the major features of the phenomena of interest.
