Chemical Engineering Transactions, 2015 In response to the fact that the physical education evaluation is unitary in evaluation content, has unclear target, fails to address comprehensive indexes and reaches general conclusion, this paper discusses the multiple evaluation of physical education

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Advanced Electronic Materials, EarlyView.Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

A canonical form for nonderogatory matrices under unitary similarity
, 2011 A square matrix is nonderogatory if its Jordan blocks have distinct eigenvalues. We give canonical forms for (1) nonderogatory complex matrices up to unitary similarity, and (2) pairs of complex matrices up to similarity, in which one matrix has distinct

Journal of the American Oil Chemists' Society, EarlyView.The statistical analysis of SAXS modelling data allows to identify the critical physicochemical parameters that have an impact on the phase behavior of crude sophorolipid batches. ABSTRACT The aqueous self‐assembly of raw sophorolipid mixtures has been studied by small angle x‐ray scattering (SAXS) to understand the impact of the composition ...

The multilevel four-stroke swap engine and its environment
New Journal of Physics, 2014 A multilevel four-stroke engine where the thermalization strokes are generated by unitary collisions with thermal bath particles is analyzed. Our model is solvable even when the engine operates far from thermal equilibrium and in the strong system–bath ...

Unitary similarity of algebras generated by pairs of orthoprojectors
, 2020 It is shown that the unitary similarity of two matrix algebras generated by pairs of orthoprojectors { P1, Q1} and {P 2,Q2} can be verified by comparing the traces of P 1, Q1, and (P1Q1)i, i = 1, 2, n, with those of P2, Q2, and (P2Q 2)i.

A note on unitary similarity preserving linear mappings on B(H)
, 2005 Let H be an infinite-dimensional complex Hilbert space. We give the characterization of surjective mappings on B(H) that preserve unitary similarity in both ...
