Abstract We present the results of a life-cycle assessment (LCA) for manufacturing and end-of-life (EoL) phases following fuel-cell hydrogen (FCH) technologies: alkaline water electrolyser (AWE), polymer-electrolyte-membrane (PEMWE), high-temperature (HT) low-temperature (LT) fuel cells (PEMFCs), together with balance-of-plant components. New inventories (LCIs), i.e., material inputs AWE, PEMWE...

PREFACE TRADOC Analysis Center (TRAC) asked the Arroyo Center to develop a framework for performing credible analysis using Distributed Interactive Simulation (DIS). This documented briefing reports on research that extends and demonstrates the credible analysis framework. The Focused Dispatch Advanced Warfighting Experiment (AWE), really a series of experiments, is used to conduct an exemplar ...

In this paper we present a new layout-driven timing model based on Asymptotic Waveform Evaluation (AWE) for improved timing analysis during routing. Our model enables the bottom-up computation of interconnect tree moments, and can be easily integrated with such a global router. Such an integration achieves incremental layout optimization, i.e., timing analysis and routing are tightly coupled, w...

Abstract Airborne wind energy (AWE) is an emerging technology for the conversion of into electricity by flying crosswind patterns with a tethered aircraft. Having proper understanding unsteady interaction air highly dynamic system during operation key to developing viable AWE systems. High fidelity simulation tools are needed correctly predict these interactions, which will provide insights des...

Agent Technology provides a new methodology in implementing workflow environments. This paper is concerned with how this shift in paradigm affects traditional security concepts like access control and separation of duty principles. The discussion focuses on the implementation of task allocation in an agent-based workflow environment (AWE) that is currently being developed. Task allocation is fu...

We present OpenAWE [1], a Matlab/Octave toolbox for solving optimal control problems with an airborne wind energy (AWE) system. For example, the toolbox can be used to find a flight path that produces maximal power (see Figure), or to find launch and landing trajectories. Parameters of the system can be optimized. Therefore, using the toolbox can accelerate thedesignprocess in the developmentof...

Approaches to and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) the left anterior descending artery (LAD) have received limited study. We examined procedural characteristics patients who underwent LAD CTO between 2012 2022 in a large multicenter PCI registry. The was target vessel 3,059 11,753 PCIs (26%). Overall technical success rates were 89% 88%, respect...
