Touchdown angle's impact on bounding gait of the quadrupeds

2011 IEEE 5th International Conference on Robotics, Automation and Mechatronics (RAM), 2011
The study of touchdown angle's impact on quadrupeds such as gait, stability, speed, height is valuable. This paper unifies two common models for quadrupeds-SLIP and planar model, gets a feasible and efficient fixed point search strategy, and proposes a gait classification method based on the event sequence.

Guidance Law to Control Impact Time and Angle

2005 International Conference on Control and Automation, 2005
This paper proposes a new guidance law to control both impact time and impact angle for a flight vehicle's homing problem, which can be applied for an efficient salvo attack of antiship missiles or a cooperative mission of unmanned aerial vehicles (UAVs).

Effect of impact angle on vaporization

Journal of Geophysical Research: Planets, 1996
Impacts into easily vaporized targets such as dry ice and carbonates generate a rapidly expanding vapor cloud. Laboratory experiments performed in a tenuous atmosphere allow deriving the internal energy of this cloud through well‐established and tested theoretical descriptions.

Ricochet Angle at Hypervelocity Impact

2024 17th Hypervelocity Impact Symposium
Abstract This work presents results of hypervelocity impact experiments, which investigate the relationship between residual velocity and impact velocity as the target obliquity is varied, with the intention to find an obliquity that results in a ricochet. Both experimental and numerical results are presented.

Impact of the Mandibular Gonial Angle on the Incidence of Angle Fractures of the Mandible

International Journal of Advanced Multidisciplinary Research and Studies
Background: Mandibular angle fractures are influenced by anatomical and dental factors, particularly gonial angle size and third molar impaction. Objective: To assess the association between gonial angle size, third molar impaction, and mandibular angle fractures.

Influence of initial heading angle for the optimal guidance law with impact angle constraint

2016 IEEE International Conference on Information and Automation (ICIA), 2016
Control of impact angle can considerably increase missile's lethality. However, large impact angle will lead to large lateral acceleration requirement during the flight. In order to avoid command saturation, one can choose initial heading angle to decrease the magnitude of the guidance command.

Guidance law with impact angle and impact time constraints

2019 Chinese Control Conference (CCC), 2019
In the terminal guidance process, in addition to ensure that the missile intercepts target with a small miss distance, achieving the desired impact angle can also improve the lethality of the missile. On the other hand, controlling the impact time can reduce the time for the target to evade interception and achieve the purpose of multi-elastic ...

Impact of impacted mandibular third molars in mandibular angle and condylar fractures

International Journal of Oral and Maxillofacial Surgery, 2010
Previous retrospective analyses prove that impacted mandibular third molars (M3s) increase the risk of angle fractures and decrease the risk of concomitant fractures to the condyle. The authors have attempted to verify these relationships and identify the underlying mechanism of injury.

Impact Time and Angle Guidance With Sliding Mode Control

IEEE Transactions on Control Systems Technology, 2009
A novel sliding mode-based impact time and angle guidance law for engaging a modern warfare ship is presented in this paper. In order to satisfy the impact time and angle constraints, a line-of-sight rate shaping process is introduced. This shaping process results in a tuning parameter that can be used to create a line-of-sight rate profile to satisfy ...

Look Angle Constrained Impact Angle Control Based on Proportional Navigation

AIAA Guidance, Navigation, and Control Conference, 2015
Two guidance schemes for nonlinear impact angle control against stationary ground targets are presented to address the issue of the look angle constraint. The guidance laws utilized are the unbiased and biased pure proportional navigation laws, for which the necessary analytical solutions are derived.
