Space-time modeling of natural disaster impacts
Journal of Economic and Social Measurement, 2011We use a space-time dynamic panel model to quantify the impact of Hurricane Ike on Texas county-level employment for the immediately affected disaster counties plus neighboring counties. While the hurricane event created a loss of over 314,000 employment in the 44 county disaster area, employment in some counties gained over 24,000 jobs as a result of

Impact – Improving patient access time: Arterial cannulation
Intensive and Critical Care Nursing, 2014The overall aim of the project was for an advanced critical care practitioner (ACCP)to develop the clinical competency of arterial catheterisation. The study examined the impact of the intervention being performed by a different staff group member.The project took the form of service development, employing a service redesign route-map.

New Impact Time and Angle Guidance Strategy via Virtual Target Approach
Journal of Guidance Control and Dynamics, 2018In this paper, a new guidance strategy is proposed for intercepting stationary and constant-velocity moving targets with desired impact time and angle via a virtual target approach, subject to nonl...

Impact time and angle constrained integrated guidance and control with application to salvo attack
Asian journal of control, 2019In this paper, a novel method is proposed to estimate the impact time (time taken to hit the target) for missiles guided by integrated guidance and control (IGC).

In this paper, we describe methods for real-time modelling explosions and their impacts on realistic deformable terrains. Our simulation method elaborates a strength and damage model for terrain material under explosion shock wave loading. The creation of the terrain deformation is tightly coupled with an adaptive mesh algorithm for dynamic level of ...

Guidance Law Design for Impact Time Attack Against Moving Targets
IEEE Transactions on Aerospace and Electronic Systems, 2018This paper considers the impact time attack problem against nonmaneuvering targets. A novel impact time guidance law is designed in two-dimensional (2-D) space, which can not only drive the estimated impact time error to zero in finite time, but also ...

The increasingly technical nature of the industrial way of life has brought about dramatic changes in the temporality of socio-environmental problems. Local, short-term, acute disturbances in the environment have turned into global, long-term, chronic perturbations, and yet both the scientific and socio-political solutions offered for environmental ...
