Fixed-Time Circular Impact-Time Guidance with Look Angle Constraint
Aerospace, 2022 A fixed-time nonlinear circular guidance law that satisfies the impact time constraint is proposed. By utilizing the geometric principle that the length of a circular arc connecting the missile and the target can be analytically calculated, the exact ...

Nonlinear optimal guidance with constraints on impact time and impact angle
AutomaticaThis paper aims to address the nonlinear optimal guidance problem with impact-time and impact-angle constraints, which is fundamentally important for multiple pursuers to collaboratively achieve a target. Addressing such a guidance problem is equivalent to solving a nonlinear minimum-effort control problem in real time.

The Impact of Agency on Time and Risk Preferences [PDF]
Nature Communications, 2018 Scholars have long argued for the central role of agency in the human experience. In this paper, we demonstrate the importance of agency in shaping people’s patience and risk tolerance. We focus on the context of resource scarcity, which has been associated with both impatience and a lack of agency.

The Impact of Timing Knowledge on the Session Problem [PDF]
SIAM Journal on Computing, 2003 Summary: The session problem is an abstraction of fundamental synchronization problems in distributed systems. It has previously been used as a test case to demonstrate the differences in the time needed to solve problems in several timing models. The goal of this paper is to compare the computational power of a family of partially synchronous models ...
