Sliding mode–based simultaneous control of impact angle and impact time

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
In this article, a sliding mode control–based nonlinear guidance scheme for controlling both impact angle and impact time simultaneously is proposed. The problem of impact angle control is first transformed to that of controlling line-of-sight angle and ...

Adjustable impact-time-control guidance law against non-maneuvering target under limited field of view

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
This article proposes an impact-time-control guidance law that can keep a non-maneuvering moving target in the seeker’s field of view (FOV). For a moving target, the missile calculates a predicted intercept point (PIP), designates the PIP as a new ...

Generalized Time-to-Go Inversion Guidance with Impact Time and Angle Constraints

Journal of Guidance Control and Dynamics
A major challenge in homing guidance is that accurately predicting the time to go for missiles is generally difficult, which limits the practical application of a certain class of guidance laws with impact-time constraints or cooperative capabilities. To

Economic Time Impacts on HTMA

International Journal of Management and Humanities, 2023
There are many stages in the medical device management lifecycle to consider, and from the planning stage to commissioning, dismantling and decommissioning, replaceing an equipment is a critical decision. This phase includes several information that help replacement decisions intelligent. Technical, monetary and safety principles are taken into account

Four-Stage Guidance Law for Impact Time and Angle Control Based on the Bezier Curve

IEEE Transactions on Aerospace and Electronic Systems
The impact-time-angle-control guidance (ITACG) law can control the impact time and angle in a wide range of applications. The previous ITACG research generally suffer from the accuracy under the time-varying velocity condition, or the axial acceleration ...

Time Motion Analysis: Impact of Scribes on Provider Time Management

The Journal of Emergency Medicine, 2018
Scribes are unlicensed professionals trained in medical data entry. Limited data exist on the impact of scribes on provider time management in the emergency department (ED). Time-motion analysis is a tool utilized in business to capture detailed movements and durations to task completion.

Submissions, decision times, and impact

Journal of Behavioral and Experimental Economics, 2023
In January 2022 I started as Editor-in-Chief of the Journal of Behavioral and Experimental Economics (JBEE). One year later I am here writing this letter, summarizing how the journal deals with submissions (and decision times), where we are in terms of our impact factor, and what we have accomplished this past year.
