Reliability of an experimental method to analyse the impact point on a golf ball during putting [PDF]
, 2015 This study aimed to examine the reliability of an experimental method identifying the location of the impact point on a golf ball during putting. Forty trials were completed using a mechanical putting robot set to reproduce a putt of 3.2 m, with four ...

Spectropolarimetry of the Deep Impact target comet 9P/Tempel 1 with HiVIS [PDF]
, 2006 High resolution spectropolarimetry of the Deep Impact target, comet 9P/ Tempel 1, was performed during the impact event on July 4th, 2005 with the HiVIS Spectropolarimeter and the AEOS 3.67m telescope on Haleakala, Maui. We observed atypical polarization

Variation in sprinkler irrigation droplet impact angle on the physical crusting properties of soils
Agricultural Water Management, 2023 The angle at which a droplet impacts determines its shearing and compaction effects on soil, which in turn affects the formation and properties of the physical soil crust.

Blast Fragment Impact of Angle-Ply Composite Structures for Buildings Wall Protection
Buildings, 2023 This paper investigates the fragment performance of several composite panels for attaching to the inside walls of a building structure. These panels were developed using different types of fiber woven fabrics (W0, W90) combined with distinct layers ...

Impact-Angle-Control Guidance Law with Terminal Constraints on Curvature of Trajectory
Mathematics, 2023 This paper presents an impact-angle-control guidance law with terminal constraints on the curvature of the missile trajectory. The formulation takes into account nonlinear kinematics and time-varying velocity, allowing for more general cases in which the

Guidance law with impact time and impact angle constraints
Chinese Journal of Aeronautics, 2013 AbstractA novel closed-form guidance law with impact time and impact angle constraints is proposed for salvo attack of anti-ship missiles, which employs missile’s normal acceleration (not jerk) as the control command directly. Firstly, the impact time control problem is formulated as tracking the designated time-to-go (the difference between the ...

Scaling of hypervelocity impact craters in ice with impact angle [PDF]
Journal of Geophysical Research: Planets, 2002 Hypervelocity oblique impacts using spherical 1 mm diameter aluminum projectiles at velocities of (5.2 ± 0.2) km s−1 were incident at angles ranging from normal (0° to the vertical) to grazing incidence (80°) onto thick polycrystalline H2O ice targets at 253 K. Data were obtained to distinguish changes in crater size and shape.

Oblique drop impact: can one infer the angle of impact?
Journal of Fluid Mechanics, 2022 During solid surface impact, a falling drop's energy is transformed into oscillations of its liquid/gas interface. We consider drop deposition during oblique impact in the capillary-ballistic regime characterized by high Reynolds number and moderate Weber number. We treat this as an inverse problem showing that post-impact observations of the frequency
