In this study, we propose an algorithmic framework for solving a class of optimal control problems. This class is associated with the minimumtime interception of moving target problems, where a plant with a given state equation must approach a moving target whose trajectory is known a priori. Our framework employs an…

Objects in our visual environment often move unpredictably and can suddenly speed up or slow down. The ability to account for acceleration when interacting with moving objects can be critical for survival. Here, we investigate how human observers track an accelerating target with their eyes and predict its time of…

Intercepting moving targets is a fundamental skill in human behavior, influencing various domains such as sports, gaming, and other activities. In these contexts, precise visual processing and motor control are crucial for adapting and navigating effectively. Nevertheless, there are still some gaps in our understanding…

Successfully intercepting a moving object requires precisely timing the optimal moment to act by integrating information about the target’s visual motion properties. Neurophysiological evidence indicates that activity in the primary motor cortex (M1) during interception preparation is sensitive to both the target’s…

— In this paper, we propose a distributed guidance law for the simultaneous interception of a stationary target. For a group of 'n' heterogeneous pursuers, the proposed guidance law establishes the necessary conditions on static graphs that ensure simultaneous target interception, regardless of the initial conditions…

Capture Authors: ['Michal Pliska' 'Matouš Vrba' 'Tomáš Báča' 'Martin Saska'] Abstract—A unique approach for the mid-air autonomous aerial interception of non-cooperating Unmanned Aerial Vehicles by a flying robot equipped with a net is presented in this paper. A novel interception guidance method dubbed Fast Response…

Interception, a fundamental visuomotor skill for activities such as driving and sports, involves two main strategies: predictive, anticipating the target’s trajectory, and prospective, actively tracking and adjusting movement. Experimentally controlled factors could potentially influence the relative usage of these…

Intercepting a moving target requires integrating visual motion information with motor preparation, yet how active motor preparation and gaze strategy jointly shape corticospinal excitability during interception planning remains unclear. We applied single-pulse transcranial magnetic stimulation over primary motor…

Multicopter Authors: ['Hailong Yan' 'Kun Yang' 'Yu‐Chieh Cheng' 'Zihao Wang' 'Dawei Li'] Abstract—Interception of low-altitude intruding targets with low-cost drones equipped strapdown camera presents a competitive option. However, the malicious maneuvers by the non-cooperative target and the coupling of the camera…

Highlights What are the main findings?1. Successful interception exhibits within-trial, speed-dependent shifts between predictive and reactive control in both gaze and manual trajectories. 2. Target occlusion reduces predictive alignment, whereas cursor occlusion has a limited impact, indicating strong reliance on…

Intercepting and avoiding collisions with moving targets are crucial skills for survival. However, little is known about how these behaviors are implemented when the trajectory of the moving target introduces variability and ambiguity into the perceptual-motor system. We developed a simple visuomotor task in which…

People can use the constant target-heading (CTH) strategy or the constant bearing (CB) strategy to guide their locomotor interception. But it is still unclear whether people can learn new interception behavior. Here, we investigated how people learn to adjust their steering to intercept targets faster. Participants…

Natural interception actions such as catching a ball require accurate motion prediction and typically involve multiple senses. Laboratory interception studies focus on vision and commonly ignore sound. Here we ask how visual and auditory signals are integrated to guide interception. Observers tracked the brief launch…

Given the increasing tensions between world powers, missile defense is a topic that is more relevant than ever. However, information on the subject is often fragmented, confusing and untrustworthy. On the other hand, we believe that an informed overview of the current status is important for decision makers and…

Human perception of space, time and motion is subject to several biases. Lab studies showed such effects in psychophysical judgements of location, but also in action-tasks, like predicting motion and intercepting. Given that similar underlying processes have been proposed for some of these biases, we tested for a…

'He Zhang' 'Xiaofeng Wang' 'Xiuyu He' 'Yabin Gao' 'Yanxu Su' 'Bo Xu'] In this paper, an optimal-damage-effectiveness cooperative-control strategy based on a damage-efficiency model and a virtual-force method is proposed to solve the pursuit-evasion problem with multiple guided missiles. Firstly, different from the…

ATT&CK Authors: ['Marco Zambianco' 'Claudio Facchinetti' 'Domenico Siracusa'] Cyber deception allows compensating the late response of defenders countermeasures to the ever evolving tactics, techniques, and procedures (TTPs) of attackers. This proactive defense strategy employs decoys resembling legitimate system…

'Roberto Vincenti Gatti'] In this study, an interference detection and mitigation method is proposed for frequency-modulated continuous-wave radar systems based on time-domain signal reconstruction. The interference detection method uses the difference in one-dimensional fast Fourier transform (1D-FFT) results between…

CCovalent inhibitors are being used more frequently in drug discovery and is expected to revolutionize how enzyme inhibitors and receptor modulators are created in the future. More than 30 covalent therapies have been approved by the US FDA as a result of this approach, which has produced a wide spectrum of effective…
