One measure of the effectiveness a blended synchronous classroom (BSC) is quality interpersonal interactions. However, qualifying complex dynamics requires more than frequency analyses verbal behaviours. This study used multimodal discourse analysis framework to describe dynamic coordination interactions in BSC. The results showed that task ownership types affect conversion between different interactive modes. Moreover, giving equal attention remote students, as evaluation indicator BSCs,...

The dynamic behaviour of the two-site coupled cavities model which is doped with ta wo-level system investigated. exact solutions in general condition are obtained via Laplace transform. simple analytical several particular cases, demonstrate clear and physical picture for quantum state transition system. In large detuning or hoppling case, states transferring between qubits follow a slow periodic oscillation induced by very weak excitation cavity mode. coupling can be interpreted as two...

HRMS is a very critical tool for companies. The recruitment text contains rich information that can provide strong support the company’s work and also improve efficiency of job seekers in finding opportunities. To this end, problem multilabel classification information, paper provides two algorithms multilayer based on supported SVM. First, same learning subclass method used sorting acquisition, then, class determined. Second, hemispherical SVM to find smallest hypersphere feature space most...

Discourse relation is an important content of discourse semantic analysis, and the study punctuation importance for relation. In this paper, we propose a method Chinese comma classification based on maximum entropy (ME). This classifies sentence with ME by extracting rich linguistic features before after commas in sentences. Experimental results show that feasible.

Abstract This research employs the fuzzy‐set qualitative comparative analysis (fsQCA) method to investigate configurations of multiple factors influencing scientific concept learning, including augmented reality (AR) technology, map (CM) strategy and individual differences (eg, prior knowledge, experience attitudes). A quasi‐experiment was conducted with 194 seventh‐grade students divided into four groups: AR CM ( N = 52), non‐CM 51), non‐AR 40), 51). These participated in a science lesson...

Currently, the teaching process of “SPSS Data Analysis and Application” course has some problems, such as a disconnect between theory practice, insufficient content that meets practical research needs, lack effective learning incentive mechanisms. This article aims to explore set reform plans combine project-based promote comprehensive improvement students’ abilities. In study, innovation optimization content, introduction learning, methods evaluation systems have been provided. By doing...

In this paper, by using the representation theorem for sublinear expectations, we give a simple proof to obtain two inequalities about sample mean independent random vectors under expectations.

Abstract The prediction and calculation of water resource demand play a crucial role in the balance supply research area. Only when area is accurately reasonably grasped, it possible to make corresponding management adjustment according actual situation process utilization, so as ensure sustainable development utilization resource. In this paper, upper middle reaches Pearl River basin taken According relationship between social economic basin, VENSIM PLE used establish dynamic model...

Accurate diagnosis is critical for the treatment planning of brain tumors. At present, classification tumor based on histological examination tissue samples. This invasive and may be subject to sampling errors. Magnetic resonance spectroscopic imaging (MRSI) a non-invasive technique that provides functional information has been proposed as tool grading. The goal this work find method (1) explicitly combines from MRSI MR (MRI); (2) considers characteristics entire lesion instead pre-selected...

Changjiang Economic Zone (CEZ) faces the urgent task to promote energy conservation and emission reduction of transportation industry. This study constructs an evaluation system for industry efficiency (TIEE) evaluates TIEEs 11 CEZ provinces in 2000–2017, using super-slack-based measure (Super-SBM) model containing undesired output. On this basis, panel data was adopted explore impactors TIEE. The main results are as follows: varied significantly In sample period, Jiangsu, Jiangxi, Zhejiang,...

Summary In geophysical data processing and interpretation, multiple inversion solution greatly increases the difficulty of interpretation seriously affect reliability accuracy results. Equivalent source models can appropriately reduce number parameters therefore possible solutions be decreased. imaging theory in gravity magnetic fields has made some progress. order to prove that method is also applicable time domain induced polarization method, three high impedance sphere were designed,...

The paper presents a modified method which bases on the traditional two-step floating catchment area and gravitational method. FCA deals with distance time obstruction by bisection method, any point within threshold range have same accessibility. Such approaches been criticized for ignoring differences are caused different factors. M2FCA addresses internal spatial distribution problem deriving fire data from smaller unit, hexagon cell. potential cross border demand-supply interaction is...
