Chapter Unmanned Aerial Systems
, 2017 Unmanned aerial platforms are a means to gather efficiently valuable aerial information to support the crisis manager for further tactical planning and deployment. They can provide continuous support to the coordinators and operators by scanning blocked sectors or establish an communication network.

Detecting and attributing climate change effects on vegetation: Australia as a test case
PLANTS, PEOPLE, PLANET, EarlyView.Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Risk Times in Mission‐Oriented Systems
Quality and Reliability Engineering International, EarlyView.ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.
