‘Pressed for Time’ – the Differential Impacts of a ‘Time Squeeze’
The Sociological Review, 2005The ‘time squeeze’ is a phrase often used to describe contemporary concerns about a shortage of time and an acceleration of the pace of daily life. This paper reviews analysis of the Health and Lifestyle Survey (HALS), 1985 and 1992, and draws upon in-depth semi-structured interviews conducted with twenty British suburban households, in order to shed ...

Data-Driven Method for Impact Time Control Based on Proportional Navigation Guidance
, 2020A data-driven impact-time-control guidance (DD-ITCG) method based on proportional navigation guidance (PNG) is presented in this study, in which the assumption of constant velocity adopted in previ...

Sliding-Mode Impact Time Guidance Law Design for Various Target Motions
Journal of Guidance Control and Dynamics, 2019In this paper, two kinds of sliding-mode guidance laws with impact time constraint are proposed for intercepting various target motions, including nonmaneuvering and maneuvering targets.

Forensic Anthropology
Academic impact is often measured in the amount of publications, number of students mentored, and what seminal research is contributed to a field. However, beyond this physical component of a person’s legacy is the influence they have on the field’s current and future practitioners and their perceptions of the field.

Sliding Mode Guidance Law for Impact Time Control Without Explicit Time-to-Go Estimation
IEEE Transactions on Aerospace and Electronic Systems, 2019This paper presents an impact time control guidance law that does not perform explicit time-to-go estimation. In order to satisfy the interception and the desired impact time constraint simultaneously, a sliding surface variable formulated as a sum of ...

Backstepping-Based Impact Time Control Guidance Law for Missiles With Reduced Seeker Field-of-View
IEEE Transactions on Aerospace and Electronic Systems, 2019This paper proposes a guidance law that achieves the desired terminal impact time without violating a seeker's field-of-view (FOV) limits. In order to derive the guidance law, kinematic conditions for impact time control are defined, and the backstepping

A Scientist's Impact over Time
Proceedings of the 20th International Database Engineering & Applications Symposium on - IDEAS '16, 2016The identification of latent patterns in big scholarly data that concern the performance of researchers is a significant task because it can potentially impact scientific careers since they are based in funding and promotion. This article investigates the temporal evolution of a scientist's impact.

Modified Time Impact Analysis Method
Journal of Construction Engineering and Management, 2012Delay claims are a common occurrence in construction projects. Many techniques have been developed to assess these delays. The time impact technique is the preferred approach for resolving complex disputes that are related to delays and delay compensation. However, this approach is time-consuming and costly to operate.
