TL;DR: This paper presents a method to use the estimated efficiency as a feedback variable in an extremum seeking control strategy for online steady state fuel consumption optimization and shows that the controller manages to find the maximum brake torque region at the given operating point both with and without external excitation.

TL;DR: It is shown that a substantial number of previously unknown cases of aortic dilatation can be identified by screening family members, and it is, however, not possible to consider anyone free of the condition, even if the aorta diameter is normal, especially at a younger age.

TL;DR: A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy based on current statistics of tumour incidence, number of Patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours and normal tissues.

TL;DR: In this article, an experimental study is carried out to investigate the combustion process in a Wartsila 34SG spark-ignited lean burn four-stroke large bore engine (bore 340 mm) by means of optical diagnostics when operating on natural gas.

TL;DR: In this paper, Almansour and Ahmad Radhwan at the Saudi Aramco Research & Development Center for preparing and analyzing the test fuels, and the authors would like to thank the Clean Combustion Research Lab for providing the engine experiment facilities.
