A Sliding Mode Observer SOC Estimation Method Based on Parameter Adaptive Battery Model
No full textAbstractErrors of a battery model will dramatically enlarge as the internal parameters of a battery varying. To reduce the systematic errors, a parameter adaptive battery model is proposed. Based on it, sliding mode algorithm is adopted to estimate the SOC of a battery. The experimental platform is constructed and the UDDS driving cycles is used to verify the method. The results show the error of SOC estimation is less than 2% and it indicates the monitoring algorithm is of great value to power batteries which are generally used in variable environment
Visualization Analysis of Food Safety Traceability System: Based on Bibliometrics
No full textIn order to summarize the evolution of food safety traceability system research in globally, 1369 research paper published in the period of 2004 to 2022 are retrieved using the words: food and traceability from the Web of Science Core Collection database and are test mined for the number of research papers, authors, countries, institutions using statistical and bibliometric indicators. Moreover, data visual analysis is carried out by plotting knowledge maps of keywords. The results show that there has been increasing interest in food research, and the number of publications about food safety traceability exhibits a growth trend. The most studied country is China that has published 331 papers with the H index ranks second. In terms of authorship, the research team mostly works with productive author cooperation in this field with cross-border and cross-regional cooperation. In terms of keywords cooccurrence, Smart contracts, blockchain, the Internet, traceability technology, and information transparency have been the research hotspots in this field in recent years. The research topics gather on the applicability of traceability technology, participation of social subjects, study on food adulteration and origin traceability based on stable isotope ratio and multi-element analysis, and solving the problem of coding confusion
Necessary and sufficient condition for Markovian-dissipative-dynamics-induced quantum discord
No full textA Markovian dissipative quantum channel can generate quantum discord from some bipartite product states if and only if it cannot be reduced to individual decoherence channels independently acting on each qudit. As a byproduct, we also prove that proper individual decoherence can transform the classical correlation into quantum discord. Our result builds a tight connection between quantum discord and collective decoherence.OpticsPhysics, Atomic, Molecular & ChemicalSCI(E)EI23ARTICLE2null8
Generation of two-mode entanglement between separated cavities
No full textWe propose a scheme for the generation of two-mode entangled states between two spatially separated cavities. It utilizes a two-level atom sequentially coupling to two high-Q cavities with strong classical driving fields. By suitably choosing the intensities and detunings of the fields and precisely controlling the dynamics, entangled coherent states and Bell states can be produced between the modes of the two cavities. The entangled states should have applications in quantum information processin. (C) 2008 Optical Society of AmericaOpticsSCI(E)EI1ARTICLE1189-1932
