Two-dimensional film cooling over a flat plate in hypersonic flow

Propulsion and Power Research, 2018
Film cooling, as one efficient active cooling method, will hopefully be used in ‘hypersonic vehicles’ in the future. The hypersonic vehicle׳s surface is more likely a flat plate than a blunt body, so the cooling characteristics of two-dimensional (2-D ...

NanoSentry: An Edge‐Deployable Unified Neural Architecture for Multi‐Domain Industrial Prognostics and Health Management

Artificial Intelligence for Engineering, EarlyView.
NanoSentry, a sub‐50 KiB unified architecture for multi‐domain prognostics, matches or outperforms models 4.5× $4.5\times $ larger across turbofan, battery, and bearing benchmarks while reducing end‐of‐life prediction error up to 5.8× $5.8\times $. Physical STM32H7 deployment confirms sub‐3 ms inference and up to 26 KiB peak SRAM without quantisation ...

A Graetz-type thermal-response superposition model for turbulent heat transfer in smooth square channels under non-uniform wall conditions

Case Studies in Thermal Engineering
Non-uniform distributions of wall temperature or wall heat flux in internal convection generate streamwise thermal-history effects that conventional local heat-transfer-coefficient (HTC) closures do not explicitly capture.

Valuation of Intangible Expenditures: Revisiting Bublitz and Ettredge (1989)

Abacus, EarlyView.
An extensive body of accounting research documents the difficulty of measuring the value of intangibles and the issues surrounding recording them in company financial statements. Early studies examined advertising and research and development (R&D) expenditures when companies began reporting them in their financials in 1972.

Digital platform strategies from an incumbent perspective: An exploration of contextual factors and connectors

European Management Review, EarlyView.
ABSTRACT Multi‐sided platform (MSP) models have become more relevant for incumbent companies, requiring them to develop MSP engagement strategies. This study sheds light on the complex process incumbents undergo in developing platform strategies. Adopting an inductive research design, we conducted interviews with 37 decision‐makers across 35 incumbent ...
