Mathematical model of movement of projectiles suitable for implementation in fire control systems
Vojnotehnički Glasnik, 1995 In the article is presented a mathematical model developed by adaptation of a mathematical model of a solid body with six degrees of freedom of movement for small range projectiles. A transformation and partial linearization of a referent model has been

On the Air Resistance of Projectiles [PDF]
Proceedings of the National Academy of Sciences, 1931 In making this study, the author had in mind its applications to the problem of meteoric impact. The different laws of resistance, heretofore proposed, contain too many empirical or hypothetical elements to permit a safe extrapolation to cosmic velocities.

Structured quantum projectiles [PDF]
Physical Review A, 2019 Matter wave interferometry is becoming an increasingly important technique in quantum metrology. However, unlike its photonic counterpart, this technique relies on the interference of particles possessing a non-zero rest mass and an electric charge. Matter waves, thus, can experience alterations in their wave-like features while propagating through ...

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor
Advanced Robotics Research, EarlyView.Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

Optics Express, 2022 Accelerating beams, of which the Airy beam is an important representative, are characterized by intensity maxima that propagate along curved trajectories. In this work we present a simple approach to directly generate accelerating beams with controllable trajectories by means of binary phase structures that consist of only a π phase step modulation in ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots
Advanced Robotics Research, EarlyView.This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Vojnotehnički Glasnik, 1996 The mathematical model of a projectile treated as a rigid body with six- degree-of-freedom motion is adapted and presented as a mathematical model for projectiles having wide initial angles and flying to great distances. The model accuracy is analysed as
