Implementing NAT Hole Punching with QUIC [PDF]
arXivThe widespread adoption of Network Address Translation (NAT) technology has led to a significant number of network end nodes being located in private networks behind NAT devices, impeding direct communication between these nodes. To solve this problem, a technique known as "hole punching" has been devised for NAT traversal to facilitate peer-to-peer ...

Development of multi-physics finite element model to investigate electromagnetic forming and simultaneous multi-point perforations of aluminium tube [PDF]
Electromagnetic forming and perforations (EMFP) are complex and innovative high strain rate processes that involve electromagnetic-mechanical interactions for simultaneous metal forming and perforations. Instead of spending costly resources on repetitive experimental work, a properly designed numerical model can be effectively used for detailed ...

Efficiently Crowdsourcing Visual Importance with Punch-Hole Annotation [PDF]
arXivWe introduce a novel crowdsourcing method for identifying important areas in graphical images through punch-hole labeling. Traditional methods, such as gaze trackers and mouse-based annotations, which generate continuous data, can be impractical in crowdsourcing scenarios. They require many participants, and the outcome data can be noisy.

Large-image Object Detection for Fine-grained Recognition of Punches Patterns in Medieval Panel Painting [PDF]
arXivThe attribution of the author of an art piece is typically a laborious manual process, usually relying on subjective evaluations of expert figures. However, there are some situations in which quantitative features of the artwork can support these evaluations.

Hilbert Transform Technique for Analyzing Mode I Crack Growth in an Pre- Stressed Monoclinic Crystalline Strip Under Punch Pressure [PDF]
arXivThe crux of the present study is to analyze the Mode I crack propagation behavior in a pre-stressed monoclinic crystalline strip of finite thickness and infinite extent. The investigation focuses on the effects of collinear Griffith cracks and dynamic punch loading induced by plane wave propagation.

Forecasting Shock-associated Energetic Particle Intensities in the Inner Heliosphere: A Proof-of-Concept Capability for the PUNCH Mission [PDF]
Solar energetic particles (SEPs) associated with shocks driven by fast coronal mass ejections (CMEs) or shocks developed by corotating interaction regions (CIRs) often extend to high energies, and are thus key elements of space weather. The PUNCH mission, set to be launched in 2025, is equipped with photometric that enables 3D tracking of solar wind ...

Obstructions to Gauging WZ Terms: a Symplectic Curiosity [PDF]
arXiv, 1994 This is an expository talk about the relation between gauging the WZ term of a one-dimensional sigma-model with a symplectic target and the existence of an equivariant moment mapping for symplectic group actions. The punch line is that the obstructions for gauging coincide with the obstructions for the existence of the moment mapping. This paper can be
