International Journal of Aerospace Engineering, 2021 Impact time control guidance (ITCG) is an important approach to achieve saturation attack on targets. With the increasing complexity of warfare requirements for missiles, an ITCG with field-of-view (FOV) constrained for antiship missiles is proposed ...

Time discretization of vibro‐impact [PDF]
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2001 Summary: We consider vibro-impact problems, i.e. mechanical systems with a finite number of degrees of freedom submitted to perfect unilateral constraints. The dynamics is basically described by a second-order measure differential inclusion for the unknown position completed with a constitutive impact law.

Impact of Screen Time on Sleep Quality
Indian Journal of Psychiatric Nursing, 2021 Background: Technology that years ago we could only dream of or read in science fiction novels, which we then actually created with much hope in their power of connecting people, has become a tool of gratification.

Field-of-View Constrained Impact Time Control Guidance via Time-Varying Sliding Mode Control
Aerospace, 2021 The problem of impact time control guidance with field-of-view constraint is addressed based on time-varying sliding mode control. The kinematic conditions that satisfy the impact time control with field-of-view constraint are defined, and then a novel ...

Mathematical Formulation of an Optimal Execution Problem with Uncertain Market Impact [PDF]
, 2015 We study an optimal execution problem with uncertain market impact to derive a more realistic market model. We construct a discrete-time model as a value function for optimal execution.

Dynamics of shallow impact cratering [PDF]
, 2005 We present data for the time-dependence of wooden spheres penetrating into a loose non-cohesive packing of glass beads. The stopping time is a factor of three longer than the time $d/v_\circ$ needed to travel the total penetration distance $d$ at the ...

Impact of time-variant turbulence behavior on prediction for adaptive optics systems [PDF]
, 2019 For high contrast imaging systems, the time delay is one of the major limiting factors for the performance of the extreme adaptive optics (AO) sub-system and, in turn, the final contrast.

Global health impact, priority and time
Developing World Bioethics, 2023 AbstractThis paper addresses normative issues that arise in relation to indicators and measures of health impact. With inspiration from Nicole Hassoun's recent proposal, the paper argues and illustrates that those interested in measuring global health impact face questions about how to prioritize among those with ill‐health, how to weigh benefits to ...
