Sustainable Development, EarlyView.ABSTRACT The Sustainable Development Goals (SDGs) are unlikely to be achieved by 2030, prompting debate about what should follow. Beyond revision, there is a need to critically examine what values and assumptions have shaped how the SDGs are conceptualised and operationalised.

Optimisation d’un moteur Stirling de type gamma
Revue des Énergies Renouvelables, 2010 La nécessité de réduire les émissions de dioxyde de carbone (CO2) a conduit à revaloriser les moteurs à combustion externe fonctionnant selon le cycle de Stirling.

Stirling Permutations, Cycle Structure of Permutations and Perfect Matchings [PDF]
The Electronic Journal of Combinatorics, 2015 In this paper we provide constructive proofs that the following three statistics are equidistributed: the number of ascent plateaus of Stirling permutations of order $n$, a weighted variant of the number of excedances in permutations of length $n$ and the number of blocks with even maximal elements in perfect matchings of the set $\{1,2,3,\ldots,2n\}$.

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Optimizing thermodynamic trajectories using evolutionary and gradient-based reinforcement learning [PDF]
, 2019 Using a model heat engine, we show that neural network-based reinforcement learning can identify thermodynamic trajectories of maximal efficiency. We consider both gradient and gradient-free reinforcement learning.

Wildlife Biology, EarlyView.Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Journal of Religious History, EarlyView.Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

Heat Transfer Intensification in Recuperative Heat Exchangers of the Stirling Engine
Engineering ProceedingsThe non-stationary mode of movement of the working fluid flow in the Stirling engine causes serious difficulties in the design of heat exchangers. In most cases, the operation of conventional commercial heat exchangers is considered under steady-state ...
