Analysis of impact damage of agglomerates: effect of impact angle

Powder Technology, 2004
Abstract The effect of impact angle on the breakage of two types of agglomerates of a synthetic detergent formulation is analysed. The agglomerates are in the same size range (0.60–0.71 and 1.00–1.18 mm) with the same formulation but have different structures arising from the processing method. In contrast to previous work reported in the literature

The Effect of Impact Angle on Knee Tolerance to Rigid Impacts

SAE Technical Paper Series, 2003
While the number of deaths from vehicle accidents is declining, probably because of mandatory seat belt laws and air bags, a high frequency of lower extremity injuries from frontal crashes still occurs. For the years 1979-1995 the National Accident Sampling System (NASS) indicates that knee injuries (AIS 1-4) occur in approximately 10% of cases ...

Fractional Guidance Law with Impact Angle Constraint and Seeker’s Look Angle Limits

Unmanned Systems, 2023
In this paper, using fractional mathematics, the guidance law of collision angle control is proposed by simultaneously taking into account the limitation of the seeker’s look angle. In order to apply the limitations of impact angle and launch in the equations of the acceleration command, the movement path from the time of launch to reaching the target

Impact-angle-constraint look angle guidance for miniature missile

2016 16th International Conference on Control, Automation and Systems (ICCAS), 2016
An engagement dynamic model is set up for the miniature missile guidance solution under the constraints of field-of-view angle and terminal impact angle. The impact-angle constraint guidance law design is converted into an optimal control problem subjected to terminal constraints.

Limbus impact on off-angle iris degradation

2013 International Conference on Biometrics (ICB), 2013
The accuracy of iris recognition depends on the quality of data capture and is negatively affected by several factors such as angle, occlusion, and dilation. Off-angle iris recognition is a new research focus in biometrics that tries to address several issues including corneal refraction, complex 3D iris texture, and blur.

Impacted third molars and risk of angle fracture

International Journal of Oral and Maxillofacial Surgery, 2002
The purpose of this study was to assess the influence of the presence, position, and severity of impaction of the mandibular third molars, on the incidence of mandibular angle fractures. A retrospective cohort study was designed for patients presenting to the Division of Oral and Maxillofacial Surgery, Toronto General Hospital (Toronto, Canada), for ...
