Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures
Advanced Engineering Materials, EarlyView.A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...

Evaluation of DC-link voltage ripple in five-phase PWM voltage source inverters
The Journal of Engineering, 2019 This paper presents the analysis of the DC-link voltage switching ripple in five-phase PWM voltage source inverters with balanced load. The analysis is particularly important for the design and selection of a DC-link capacitor making it possible to meet ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

High-CMRR stray-insensitive switched-capacitor differential input stage for A/D convertors
Electronics Letters, 1986 A new stray-insensitive switched-capacitor differential input circuit for A/D convertors is presented. This circuit, which uses only switches and capacitors, completely rejects common-mode signals regardless of the values of the design capacitors and the stray capacitances.

Control of Dual-Opposed Stirling Convertors with Active Power Factor Correction Controllers [PDF]
, 2006 When using recently-developed active power factor correction (APFC) controllers in power systems comprised of dual-opposed free-piston Stirling convertors, a variety of configurations of the convertors and controller(s) can be considered, with ...

T-WAS and T-XAS algorithms for fiber-loop optical buffers
, 2020 In optical packet/burst switched networks fiber loops provide a viable and compact means of contention resolution. For fixed size packets it is known that a basic void-avoiding schedule (VAS) can vastly outperform a more classical pre-reservation ...
