Deep Learning Based Situation Awareness for Multiple Missiles Evasion [PDF]

arXiv
As the effective range of air-to-air missiles increases, it becomes harder for human operators to maintain the situational awareness needed to keep a UAV safe. In this work, we propose a decision support tool to help UAV operators in Beyond Visual Range (BVR) air combat scenarios assess the risks of different options and make decisions based on those ...

Robust control for uncertain air-to-air missile systems [PDF]

arXiv
Air-to-air missiles are used on many modern military combat aircraft for self-defence. It is imperative for the pilots using the weapons that the missiles hit their target first time. The important goals for a missile control system to achieve are minimising the time constant, overshoot, and settling time of the missile dynamics.

Future state prediction based on observer for missile system [PDF]

arXiv
Guided missile accuracy and precision is negatively impacted by seeker delay, more specifically by the delay introduced by a mechanical seeker gimbal and the computational time taken to process the raw data. To meet the demands and expectations of modern missiles systems, the impact of this hardware limitation must be reduced. This paper presents a new

Label up: Learning Pulmonary Embolism Segmentation from Image Level Annotation through Model Explainability [PDF]

arXiv
Pulmonary Embolisms (PE) are a leading cause of cardiovascular death. Computed tomographic pulmonary angiography (CTPA) stands as the gold standard for diagnosing pulmonary embolisms (PE) and there has been a lot of interest in developing AI-based models for assisting in PE diagnosis. Performance of these algorithms has been hindered by the scarcity of

Nonlinear dynamics of air invasion in one-dimensional compliant fluid networks [PDF]

arXiv
Vascular networks exhibit a remarkable diversity of architectures and transport mechanisms across biological systems. Inspired by embolism propagation in plant xylem - where air invades water-filled conduits under negative pressure - we study air penetration in compliant one-dimensional hydrodynamic networks experiencing mass loss by pervaporation ...
