Generic and flexible self-correction method for nonlinearity-induced phase error in three-dimensional imaging

In three-dimensional imaging employing phase-shifting profilometry(PSP), the nonlinear response of projector and camera makes the fringe gray distribution non-sinusoidal, which further leads to phase error. Although the double 3-step phaseshifting method is simple and effective, it needs to add an additional set of fringe sequences, which reduces the measurement efficiency. To this end, this paper introduces a generic and flexible self-correction method for nonlinearity-induced phase error.First, according to the nonlinearity-induced phase error model, we introduce an additional wrapped phase with a phase difference of π/3. The error waveform of the two wrapped phases is opposite but not coincident. Then, we introduce an estimation algorithm for the additional wrapped phase offset. Finally, we fuse the two wrapped phases to correct the phase error. Experiments confirm that the root mean squared error of the proposed method is 64.1% lower than that of the traditional method and 13.3% lower than that of the Hilbert transform method. The proposed method does not require any additional fringes or hardware assistance and can be easily extended to 4-step or 5-step PSP.

HOW EFFECTIVE IS ERROR FEEDBACK ON SELF-CORRECTION IN L2 WRITING?——A CASE STUDY IN GUANGZHOU UNIVERSITY

The contemporary emphasis on learner-centeredness and autonomy suggests that in some contexts, learners' self-correction of mistakes might be more beneficial for language learning than teacher's direction correction. A case study was constructed to discover how effective the target students could self-correct their writing mistakes against the teachers' feedback. The findings may give some insights into the role of self- correction in teaching L2 writing.

Simulating an underwater vehicle self-correcting guidance system with Simulink

Underwater vehicles have already adopted self-correcting directional guidance algorithms based on multi-beam self-guidance systems, not waiting for research to determine the most effective algorithms. The main challenges facing research on these guidance systems have been effective modeling of the guidance algorithm and a means to analyze the simulation results. A simulation structure based on Simulink that dealt with both issues was proposed. Initially, a mathematical model of relative motion between the vehicle and the target was developed, which was then encapsulated as a subsystem. Next, steps for constructing a model of the self-correcting guidance algorithm based on the Stateflow module were examined in detail. Finally, a 3-D model of the vehicle and target was created in VRML, and by processing mathematical results, the model was shown moving in a visual environment. This process gives more intuitive results for analyzing the simulation. The results showed that the simulation structure performs well. The simulation program heavily used modularization and encapsulation, so has broad applicability to simulations of other dynamic systems.

How Can Correction Improve Students' Writing

Writing is one of the required abilities in learning a foreign language and it is the most difficult to master as well. Though nearly all the students have learned English for at least six years, when it comes to writing, they are incompetent for it and mistakes appear in their writing time and again. This article means to analyze the reasons of mistakes and attempts to offer some possible means to correct them. Thus students’ writing can be improved.

Different Policies to Different Errors

Making of errors is an inevitable and indeed necessary part of the learning process.We should have positive attitude towards errors and the policies towards error correction should be flexible and adaptable.Teachers should have different policies towards different errors.For example,pre-systematic error should be tolerated.The immediate correction is ineffective.The systematic error should be corrected immediately,with the help of the teacher.And the teacher should encourage the student to discover and correct the post-systematic error by themselves.

Probabilistic Chain Teleportation of a Qutrit-State

We investigate chain teleportation of a qutrit-state via the non-maximally two-qutrit entangled channels.For the case of four parties,the efficiencies of two chain teleportation protocols,the separate chain teleportation protocol(SCTP),and the global chain teleportation protocol (GCTP),are calculated.In SCTP the errors are corrected betweenevery step while in GCTP the errors are corrected only at the end.Furthermore,we present a piecewise global chainteleportation protocol (PGCTP) for keeping away from the inconvenience of error-correction of GCTP.We show thatPGCTP is more efficient than SCTP.

The Inspirations of LIFT on Marking of EFL Writing in Chinese Secondary Classrooms

What constitutes the most effective marking of EFL learners' writing in secondary schools is still the focus of EFL teachers. Traditional feedback is not as successful as it is expected to be because students haven't concerned themselves with the teacher's comments too much.LIFT(Learner Initiated Feedback Technique), as a creative means of enhancing marking, has been tested and adopted in foreign language teaching. Through the introduction of current conditions of marking of EFL writing, selfcorrection, peer-marking and feedback workshop in EFL secondary classrooms are proposed in light of the theory of LIFT.

A COMPARISON OF THE USAGE OF ENGLISH TENSES BY UNDERGRADUATE STUDENTS OF DIFFERENT LEVELS OF ABILITY RECEIVING DIFFERENT TYPES OF ERROR TREATMENT THROUGH THE USE OF COMPUTER-ASSISTED LANGUAGE LEARNING

This study investigated the effects of different error treatments—overt correction and self-correction—on the usage of English tenses of Thai undergraduate students. Both treatments were given through CALL. Levels of the students (High, Moderate, and Low) served as a moderator variable. The study was conducted with 219 first-year undergraduates of Huachiew Chalermprakiet University in a 2x3 factorial design. At the beginning of the study, all subjects were pre-tested by using the Test of English Tenses Usage (TETU) developed by the researcher. After they completed 9 CALL lessons in 3 weeks, the post-test was conducted. Two-way Analysis of Variance (ANOVA) and descriptive statistics were used to analyze and to explain the data. Results showed that the error treatment factor did not have a significant effect on the usage of tenses while the level factor did. The interaction effect between the treatment and the level was not found. The three tenses that showed the highest percentage of correct answers: Simple Present, Present Continuous, and Past Continuous, while the most difficult tenses for them were Present Perfect and Past Perfect.

Path planning of a free-floating space robot based on the degree of controllability

An effective and more efficient path planning algorithm is developed for a kinematically non-redundant free-floating space robot(FFSR) system by proposing a concept of degree of controllability(DOC) for underactuated systems. The DOC concept is proposed for making full use of the internal couplings and then achieving a better control effect, followed by a certain definition of controllability measurement which measures the DOC, based on obtaining an explicit and finite equivalent affine system and singular value decomposition. A simple method for nilpotent approximation of the Lie algebra generated by the FFSR system is put forward by direct Taylor expansion when obtaining the equivalent system. Afterwards, a large-controlla- bility-measurement(LCM) nominal path is searched by a weighted A* algorithm, and an optimal self-correcting method is designed to track the nominal path approximately, yielding an efficient underactuated path. The proposed strategy successfully avoids the drawback of inefficiency inherent in previous path-planning schemes, which is due to the neglect of internal couplings, and illustrative numerical examples show its efficacy.

The Role of Social Media in Providing Crisis Information in China:A Critical Evaluation of the Tianjin Fire Incident

This paper focusses on the information asymmetry in crisis news after a serious incident in Tianjin, China, in 2015. The incident caused enormous damage and resulted in societal unrest because of the lack of reliable information from the formal media channels. Social media — micro blogs —played a major role in reporting on crisis situations. We divided netizens(i.e., the citizens of the net)into high and low types according to their information-critical level to the crisis news. The data shows information deterioration on the crisis news, related to the netizens’ information-critical level. For the traditional media there is the opportunity to use information quality distortion to make more marginal profits. This is possible only if the citizens’ information stays under a certain quality level. The result is overprovision of low quality news and high quality news driven out of the market, whereupon adverse selection(i.e., a lack of symmetric information) appears. However, by adopting a process view, we found self-correcting mechanism(i.e., dying out of rumors) of the social media communities in China.We provided a agent-base model and simulation to show that the more media exist in the market, the faster speed of the information deterioration, but also the capacity to ‘discuss’ rumors.
