Functions, Values & Inadequacies ------An Evaluative Discussion of Pigai Intelligent Online English Writing Correction System in View of Second Language Acquisition
Authors: Yan Wang 
Published: July 2019

Abstract
The recent development of AI technology leads to either the belief that the possibility for it to replace human being has been increasing, or the disbelief that AI technology is still of that potency. This research is to evaluate an intelligent online English writing correction system known as Pigai from the perspective of the second language acquisition. The research is made available (1) in light with learning theories such the Input Hypothesis, as well as investigation of the learners in China; (2) by discussion of functions found in the system, and (3) with analysis of values and inadequacies as demonstrated with the system. The thesis finally argues that writing practice with Pigai system may improve learners’ second language writing skills and language competence, but partially; and will not be of much help in promoting learners’ humanities quality.

Published: July 2019

Abstract
In the process of digital signal transmission, due to noise and other interference signals, the code element waveform will produce some changes. RA code can encode and decode in linear time, which is one of the key techniques of channel coding. Interleaver is a very important part of RA code encoder, so its performance affects the performance of RA code. A S-pseudo-random interleaver and deinterleaver is designed in this paper, and the model is verified by simulation. The experimental results show that the bit error rate (BER) of interleavers with different interleaver lengths is significantly different. The longer the interleaver length is, the better the performance of the interleaver is, and the closer to the Shannon limit is.

Published: July 2019

Abstract
With the change of micro environmental variables such as internet technology, AI technology, the upgrade of education consumption, there has been a profound change in education, and then the value network created by undergraduates, teachers, employers and other stakeholders will be also changed. The crisis faced by education is the multiple trust crises among stakeholders, and the contradiction between the personal needs of undergraduates (personal desire for development, personal maturity cycle, personal growth rate, etc.) and the One-size-fits-all teaching is the main aspect of the multiple trust crises. Therefore, establishing the concept of adaptive learning and shifting the focus of reform from One-size-fits-all teaching to personalized education is the way for educational reform in the future. The reform should firmly establish the principles of cognitive science obeying, interest activating, diversity cultivating, and balance keeping. Evidence-based education, mastery learning, etc. are the core elements of design of adaptive learning environment. The theoretical base of this research is Piaget’s cognitive developmental psychology and adaptive learning theory. It applies educational theories and educational techniques, such as evidence-based education, OBE, mastery learning, etc., to the construction of the adaptive learning environment. It provides an overview of the main modules and algorithms of the environment, with the aim of using the top-level design to enable the hidden functions of education by the soft environment.
Sleep Staging Based on Energy and Complexity Characteristics of Sleep EEG Signals
Authors: Li Xiaobo , Ren Chunhui , Zou Xiao 
Published: July 2019

Abstract
Nowadays, people’s sleep problems become more and more serious with the increase of pressure in social life. Sleep staging is the key step in the diagnosis of sleep diseases. The traditional manual staging has the drawbacks of consuming manpower and time, and the standard is difficult to unify. In order to effectively realize automatic sleep staging, a sleep staging method based on EEG energy characteristics and complexity is proposed in this paper. Because the complexity of EEG signal and the energy of each characteristic wave change regularly with the different sleep period, sleep period can be distinguished effectively based on these features. Firstly, FIR band-pass filter is used to extract the characteristic wave from EEG signal and calculate its energy. Then the complexity of each sleep period is calculated. Finally, the improved support vector machine is used to classify the sleep stage. The experimental results show that the method proposed in this paper is simple and effective, and has good clinical application value.

Authors: Guo Chunsheng , Cai Wenyi , Li Jinyuan , Wang Sijin , Wei Lei , Li Yaosheng 
Published: July 2019

Abstract
To evaluate the reliability of endure high voltage when IGBT is turned off and eliminate the defective devices, HTRB (High Temperature Reverse Bias) test is one of the necessary tests for IGBT before it’s produced. According to the IEC standard, DUTs (Device Under Test) are usually blocked, and bear forward bias voltage, which is preferably 80% of VCESmax. During the HTRB test, DUT junction temperature should be set at maximum virtual junction temperature Tvj(max) which is usually between 125°C to 150°C. Due to high voltage, even though the leakage current is very low, high-power semiconductor devices generate dissipated power during HTRB test, which lead to junction temperature increase. And to access the reliability accurately, the rise of temperature cannot be neglected. To insure the test is carry out at standard temperature, this paper monitors DUTs junction temperature by using leakage current as a TSEP (Temperature Sensitive Electrical Parameter),. The experiment proofs that higher the junction temperature is, the more accurate the measure results will be, in the operating temperature range. In this paper, thermal resistance measurement is used to evaluate the validity of this method.

Published: July 2019

Abstract
The drive machine and the braking system are quite important to the safety of lifts. The redundancy-type brake is given usually more than one brake responsibility. In order to know the safety situation of the braking performances of drive machines after China’s new regulations issued, the type test results of 57 drive machine samples are summarized and analysed, including the sets of mechanical parts, the braking performance when all groups work together and the braking performance when each group works separately. The result shows that most (about 93%) drive machines are equipped with 2 sets of mechanical braking parts. The average of the ratio of braking torque to output torque is 3.16. The average of the sum of braking torque that generated by every group works separately just equals to the whole braking torque.

Protein Secondary Structure Online Server Predictive Evaluation
Authors: Zhu Shuping , Liu Yihui 
Published: July 2019

Abstract
The prediction of protein secondary structure is of great significance for studying the function of proteins and for making progress in the field of bioinformatics. Since 1951, the secondary structure of predicted proteins has been proposed. After 66 years of development, the prediction method has been continuously optimized, and the accuracy rate has exceeded 80%. Continuous Automated Model Evaluation (CAMEO) gives a prediction of protein tertiary structure evaluation for many current prediction methods, and secondary structure evaluation has not been achieved. In response to this problem, six servers were selected: PSRSM, MUFOLD, SPIDER, RAPTORX, JPRED and PSIPRED to evaluate the predicted secondary structure. The latest released protein from the Protein Data Bank (PDB) was applied just to ensure that the test set is not included in the training set. In the experiments of which protein homology was 30%, 50%, 70% and 90%, the obtained accuracy of PSRSM for Q3 was 91.44%, 88.12%, 90.17% and 87.39%, respectively. And the accuracy is higher than the best server among other prediction serves---MUFOLD, by 3.19%, 1.33%, 2.19% and 1.72%, correspondingly. It is proved that PSRSM has a better prediction quality than other servers for the same kind of homology data, the Sov and boundary accuracy as well. This paper focuses on analyzing the operating methods and corresponding results of various servers, thus, it is safe to say that the prediction of protein secondary structure should be studied on perspectives of big data, templates and deep learning.
