Journal of Linguistic Anthropology, EarlyView.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Study: Algorithms for rocket engine thermochemistry
, 2021 This thesis compiles the process of upgrading two libraries (INIST and HGS) which provide to their users the thermodynamics properties and algorithms needed to analyse liquid rocket engine feed cycles. First, the Thermodynamic theory for real fluids, ideal fluids and mixtures is reviewed, as well as the algorithms and tools that the libraries implement.

Artificial intelligence and corporate ideation systems
Journal of Product Innovation Management, EarlyView.Abstract Many companies leverage the creativity of their employees to gather ideas for innovations. These ideas are collected, saved, and evaluated via platforms known as corporate ideation systems. Moderated ideation systems (ideation 2.0) emerged as a solution to address the limitations of traditional, rather passive ideation systems (ideation 1.0 ...

Sequential Detector Statistics for Speculative Bubbles
Journal of Time Series Analysis, EarlyView.ABSTRACT We propose a heteroskedasticity‐robust locally best invariant (LBI) statistic to test the hypothesis of a unit root against the alternative of an explosive root associated with speculative bubbles. Compared to existing alternatives such as Dickey‐Fuller type tests, the LBI statistic has a standard limiting distribution and greater power ...

The development of power specific redlines for SSME safety monitoring [PDF]
Over the past several years, there has been an increased awareness in the necessity for rocket engine health monitoring because of the cost and complexity of present and future systems. A current rocket engine system, the Space Shuttle Main Engine (SSME),
