Journal ArticleDOI
Systematic exploration of scenario spaces
TL;DR: This paper develops a systematic methodology, Scenario Diversity Analysis (SDA), which addresses the problems of broad span vs conservatism and imbalance, and generates scenario sets where the scenarios are in a quantifiable sense maximally different.
Proceedings ArticleDOI
An air hybrid for high power absorption and discharge
TL;DR: In this article, a model of an air hybrid with two air tanks was created using the engine simulation code GT-Power and the results from the simulations were combined with a driving cycle to estimate the reduction in fuel consumption.
Journal ArticleDOI

TL;DR: The majority of patients who will develop circulatory instability with a pronounced fall in arterial blood pressure can be identified by Poincare plots of R-R intervals and spectral analysis of HRV.
Proceedings ArticleDOI
Introductory Study of Variable Valve Actuation for Pneumatic Hybridization
TL;DR: In this article, a Scania D12 single-cylinder diesel engine has been converted for pneumatic hybrid operation and tested in a laboratory setup using variable valve timing to compress air during deceleration and expand air during acceleration.
