Span programs and quantum time complexity [PDF]

open access: yesProceedings of MFCS 2020, LIPIcs, vol. 170, pp. 26:1--26:14, 978-3-95977-159-7 (2020), 2020
Span programs are an important model of quantum computation due to their tight correspondence with quantum query complexity. For any decision problem $f$, the minimum complexity of a span program for $f$ is equal, up to a constant factor, to the quantum query complexity of $f$. Moreover, this correspondence is constructive.

DYNAMIC SIMULATION AND COMPOSITION CONTROL IN A 10 L MIXING TANK

open access: yesReaktor, 2012
The open loop experiment of composition dynamic in a 10 L mixing tank has been successfully done inlaboratory. A 10 L tank was designed for mixing of water (as a stream-1) and salt solution (as astream-2 with salt concentration, c2 constant). An electric

Digital core: study of textural heterogeneities in a rock

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2023
Relevance. When real fluid flows through channels of limited dimensions, it experiences a constant loss of mechanical energy (hydraulic resistance) due to the action of viscous friction.

A Fast Graph Program for Computing Minimum Spanning Trees [PDF]

open access: yesEPTCS 330, 2020, pp. 163-180, 2020
When using graph transformation rules to implement graph algorithms, a challenge is to match the efficiency of programs in conventional languages. To help overcome that challenge, the graph programming language GP 2 features rooted rules which, under mild conditions, can match in constant time on bounded degree graphs.
