The sublimation effect in the technology of centrifugal arc dispersion of tungsten carbide

open access: yesИзвестия высших учебных заведений. Поволжский регион:Технические науки
Background. Sublimation during high-temperature fracture of hard alloys affects the formation of a fraction of ultrafine particles. For subsequent technologies of using powder raw materials, this effect leads to significant changes in the molding modes ...

Uncertain futures: Imaginaries, narratives, and calculative technologies

open access: yes, 2019
Dynamic capitalist economies are characterised by relentless innovation and novelty and hence exhibit an indeterminacy that cannot be reduced to measurable risk. How then do economic actors form expectations and decide how to act despite this uncertainty?

Calculation of tightly coupled transmission linesfor MMIC/MHMIC technology

open access: yesElectronics Letters, 1998
Analyses and calculations are performed to provide design equations for new tightly coupled transmission lines, compatible with MMIC/MHMIC technology . In this design, short subsections of different lines loaded by MIM capacitors are connected together to achieve the tight coupling needed.
