Generative AI—the Transgression of Technology
Systems Research and Behavioral Science, EarlyView.ABSTRACT This article offers a systems‐theoretical analysis of generative artificial intelligence (GenAI) grounded in Niklas Luhmann's sociology of technology. It addresses a central conceptual problem: How GenAI can be understood within a theoretical framework that has traditionally defined technology as a means of stabilising action through causal ...

An iterative dynamic chemical stiffness removal method for reacting flow simulations
Propulsion and EnergyAn iterative dynamic chemical stiffness removal method (IDCSR) based on quasi-steady-state approximation (QSSA) is proposed. The IDCSR method is built on a previously developed non-iterative method which has proved to work well for small timestep sizes ...

Critical Temperature to Auto-Ignition of Leaves
Journal of the Japanese Institute of Landscape Architects, 1984 熱気流による樹木の発火危険を探るため, 発火時の葉温を既往の実験成果から整理するとともに, その検証のための実験を行った。既往の実験姓として空気温度の測定であったため藻内への熱の貯留から発火に至る経過がつかみ得なかった。本実験では藻の麺が発火する時点で近傍の遮敝板内の測点の値を記録することにより, 輻射熱の影響のない適正な葉温 (発火限界温度) を把握することができた。

The two-stage auto-ignition of hydrocarbons and "knock" [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1938 Abstract The investigations of Townend and co-workers (1934) have revealed that the spontaneous ignition of higher paraffins in admixture with air consists in certain temperature ranges usually between 270 and 400°C., of a two-stage process, preceded by a time interval t1 prior to the appearance of a cool flame, and a subsequent ...

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites
Safety Science and Technology, EarlyView.Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Journal of Vinyl and Additive Technology, EarlyView.A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...
