This paper explores a fast charger based on microcontroller for LiCoO2 battery module. The main structure of the proposed system is the power factor corrector with a full-bridge phase-shift converter, its power factor upgrade close to 1.0, as well as to change the charging strategy according to the battery module's state of charge. Furthermore, the full-bridge phase-shift converter control chip communicates...
Tensor decomposition of fMRI data has gradually drawn attention since it can explore the multi-way data's structure which exists inherently in brain imaging. For multi-subject fMRI data analysis, time shifts occur inevitably among different participants, therefore, shift-invariant tensor decomposition should be used. This method allows for arbitrary shifts along one modality, and can yield satisfactory...
Learning metacognitive listening strategies and specializing in the implementation of such strategies enable not only a more efficient use of time but also easier and more sustained listening. This research examines first-year university students' awareness level of metacognitive listening comprehension strategies (MLCS) on learning English as a Foreign Language (EFL). We used Vandergrift et al.'s...
Support innovative product to cross chasm or assist design innovative product are very important business opportunity for company to occupy market share. In this paper we propose two kinds use of weak-tie to develop meaningful innovation for increasing companies¡¦ competition.
The purpose of this study is to elaborate the ubiquitous problem-base learning(UPBL) model with collaborative learning competence and to investigate the differences of collaborative learning and scientific inquiry competencies between experienced and novice students in UPBL. Computerized ecology observation competence assessment (CEOCA) was integrated into three trips of Chiku Wetland inquiry activities...
The spatial components included in complex-valued functional magnetic resonance imaging (fMRI) data are generally assumed to be noncircular signals. In this paper, we try to quantitatively investigate the noncircularity of fMRI with a measure called the degree of impropriety (DOI). Two semi-blind complex ICA algorithms, the kurtosis maximization (KM) algorithm suitable for separating noncircular sources...
This paper reports the results obtained using TbFe and FeCo alloys as the electrodes of MgO-based perpendicular magnetic tunnel junctions (pMTJs). Without annealing treatment, the as-deposited structure showed MgO (001) crystalline texture. The tunnel magnetoresistance (TMR) ratio measured from the patterned cell of size 3 6 m was 9.5% at room temperature. However, the coercivities...
