Improving autoencoder-based unsupervised damage detection in uncontrolled structural health monitoring under noisy conditions

Structural health monitoring is widely utilized in outdoor environments,especially under harsh conditions,which can introduce noise into the monitoring system.Therefore,designing an effective denoising strategy to enhance the performance of guided wave damage detection in noisy environments is crucial.This paper introduces a local temporal principal component analysis(PCA)reconstruction approach for denoising guided waves prior to implementing unsupervised damage detection,achieved through novel autoencoder-based reconstruction.Experimental results demonstrate that the proposed denoising method significantly enhances damage detection performance when guided waves are contaminated by noise,with SNR values ranging from 10 to-5 dB.Following the implementation of the proposed denoising approach,the AUC score can elevate from 0.65 to 0.96 when dealing with guided waves corrputed by noise at a level of-5 dB.Additionally,the paper provides guidance on selecting the appropriate number of components used in the denoising PCA reconstruction,aiding in the optimization of the damage detection in noisy conditions.

INVERSE KINEMATICS FOR A 6 DOF MANIPULATOR BASED ON NEURAL NETWORK

A methodology is presented whereby a neural network is used to learn the inverse kinematic relationships of the position and orientation of a six joint manipulator. The arm solution for the orientation of a manipulator using a self organizing neural net is studied in this paper. A new training model of the self organizing neural network is proposed by thoroughly studying Martinetz, Ritter and Schulten′s self organizing neural network based on Kohonen′s self organizing mapping algorithm using a Widrow Hoff type error correction rule and closely combining the characters of the inverse kinematic relationship for a robot arm. The computer simulation results for a PUMA 560 robot show that the proposed method has a significant improvement over other methods documented in the references in self organizing capability and precision by training process.

Solution to reinforcement learning problems with artificial potential field

A novel method was designed to solve reinforcement learning problems with artificial potential field.Firstly a reinforcement learning problem was transferred to a path planning problem by using artificial potential field(APF),which was a very appropriate method to model a reinforcement learning problem.Secondly,a new APF algorithm was proposed to overcome the local minimum problem in the potential field methods with a virtual water-flow concept.The performance of this new method was tested by a gridworld problem named as key and door maze.The experimental results show that within 45 trials,good and deterministic policies are found in almost all simulations.In comparison with WIERING's HQ-learning system which needs 20 000 trials for stable solution,the proposed new method can obtain optimal and stable policy far more quickly than HQ-learning.Therefore,the new method is simple and effective to give an optimal solution to the reinforcement learning problem.

Promoting learner autonomy through strategy-based instruction

Learner autonomy is a matter of explicit or conscious intention. Learners cannot accept responsibility for their own learning unless they have some ideas of what, why, and how they are trying to learn. This paper argues that learner autonomy may be promoted through strategy-based instruction. The intent of strategy-based instruction is to help all students become better language learners. When students begin to understand their own learning processes and can exert some control over these processes, they tend to take more responsibility for their own learning and become more autonomous. Teachers may conduct strategy-based instruction by complementing such activities as preparation, practice, evaluation and expansion.

A Quantized Kernel Least Mean Square Scheme with Entropy-Guided Learning for Intelligent Data Analysis

Quantized kernel least mean square(QKLMS) algorithm is an effective nonlinear adaptive online learning algorithm with good performance in constraining the growth of network size through the use of quantization for input space. It can serve as a powerful tool to perform complex computing for network service and application. With the purpose of compressing the input to further improve learning performance, this article proposes a novel QKLMS with entropy-guided learning, called EQ-KLMS. Under the consecutive square entropy learning framework, the basic idea of entropy-guided learning technique is to measure the uncertainty of the input vectors used for QKLMS, and delete those data with larger uncertainty, which are insignificant or easy to cause learning errors. Then, the dataset is compressed. Consequently, by using square entropy, the learning performance of proposed EQ-KLMS is improved with high precision and low computational cost. The proposed EQ-KLMS is validated using a weather-related dataset, and the results demonstrate the desirable performance of our scheme.

Design and Validation of Leadership Education Integrating Simulation and Project Based Learning

All engineering students need to develop their important skills of leadership in project management. Many students have never been leaders in their social and school lives. A leading role is unimaginable to them and hence they cannot imagine how to achieve it. The purpose of this paper is to report a result of a new leadership education program which links a variety of simulated experiences with real actions of students in project based learning （PBL） to develop their leadership ability. The first step is for graduate students to gain knowledge in the leadership arena. Then, they utilize simulation to experience leadership actions many times. Simulation provides a safe environment in which they can try out many different approaches in taking leadership in various situations. In the next step, students as a team utilize PBL, so that the above simulated experiences can help them to actually take leadership. Students can apply trained leadership to actual projects. It is highly effective to apply conscious leadership to a project aimed at a specific goal in limited circumstances. This education repeats both of the steps above, raising leadership abilities in an upward spiral. In terms of students＇ evaluation of leadership education in project management, 360-degree assessments were carried out by teachers, senior, and junior students before and after the course, and authors compare their assessments thoroughly. As a result, authors are assured that students not only gained knowledge but also raised leadership abilities in their actions after this education. Six months after the time of leadership education employing simulated experiences and PBL, follow-up interviews were conducted on its effects. Authors recognized the cyclic period that students apply simulated experiences to PBL and that they seek different approaches in simulation for solving problems found in reality. This research concludes that this cycle of simulator and PBL can produce effective leadership actions.

Promoting Collaborative Learning in Dynamics Remedial Course

The paper reports on collaborative learning approach to a remedial class in Dynamics. It uses the Kolb model and 4MAT learning system to introduce a learning cycle based on collaborative problem solving exercises. The teaching approach based on learning cycle is described giving examples of different teaching elements applied in particular quadrants of the learning cycle. The attitude of students and their different approaches to, learning are presented and discussed in detail. The results presented cover different aspects of the course delivery and students＇ perception. The results include students＇ statistics with respect to their registration and previous history related to the course, their motivatiion, assessment and satisfaction with the approach applied. This initial introduction of cooperative activities into the remedial Dynamics class can be assessed as a positive step in increasing student understanding and performance in the course. The students＇ positive reception of the non-traditional teaching method and their overall improved performance seem to confirm the advantages of collaborative leaming. In terms of the final grades, the results of the experiment were not as good as expected. However, the application of 4MAT learning system which exposed students to a variety of diverse learning styles improved the quality of education. The positive aspect of the experiment was the attitude of students and their acceptance of the new mode of course delivery. In conclusion collaborative learning could be extended beyond remedial groups to normal student classes.

The Code-Switching Dimension of Guided Fantasies in Young Learner L2 Classroom

The paper reports on a study of young L2 （second language） English learners＇ dual code use as activated through a series of specially designed guided fantasies. The original concept of guided fantasies as a monolingually organised relaxation technique was extended to the area of bilingual reception and production. The goal was to examine the relationship between child imaginative faculty and a tendency to transfer understandings across the L1 （first language） and L2. The research consisted in exposing a class of I 0 nine-year-old children to eight guided fantasies expected to playfully attract their conscious attention to language properties and enable them to profit from L1 knowledge in L2 learning. The data were collected through the heuristically oriented qualitative study drawing on participant observation accompanied by field notes and recordings of student behaviours. The findings highlighted guided fantasies in their redefined form as a useful tool for encouraging young learners to rely on L 1 competence in making sense of L2 underlying principles.

Tri-party deep network representation learning using inductive matrix completion

Most existing network representation learning algorithms focus on network structures for learning.However,network structure is only one kind of view and feature for various networks,and it cannot fully reflect all characteristics of networks.In fact,network vertices usually contain rich text information,which can be well utilized to learn text-enhanced network representations.Meanwhile,Matrix-Forest Index(MFI)has shown its high effectiveness and stability in link prediction tasks compared with other algorithms of link prediction.Both MFI and Inductive Matrix Completion(IMC)are not well applied with algorithmic frameworks of typical representation learning methods.Therefore,we proposed a novel semi-supervised algorithm,tri-party deep network representation learning using inductive matrix completion(TDNR).Based on inductive matrix completion algorithm,TDNR incorporates text features,the link certainty degrees of existing edges and the future link probabilities of non-existing edges into network representations.The experimental results demonstrated that TFNR outperforms other baselines on three real-world datasets.The visualizations of TDNR show that proposed algorithm is more discriminative than other unsupervised approaches.

Rokeya Sakhawat Hossain： An Unknown Voice of Bengal

The whole world knows that England has her Mary Wollstonecraft and France has her Simone de Beauvoir as feminists, but the world knows a very little that Bengal also has her Rokeya Shakhawat Hossain, an intrepid feminist, who struggled till the last day of her life for the perfectly right assessment of the neglected Indian women, was born in 1880, in Pairaband, a small village in British India which now lies in the north-western part of present-day Bangladesh. She pioneered women＇s advancement and led the way to enlightening and empowering women breaking all the traditional social barriers. When the whole women folk were utterly distressed, deprived, and drowned under the dirt of illiteracy, fanaticism, superstitions, and prejudices and could not think of equal rights and freedom, she raised her voice through her writings and worked to uplift the fortune of women, instilled a sense of renaissance in them and led them to tasting the flavor of freedom opposed to the current of patriarchal social views. Based on this bold attitude toward female emancipation, Rokeya can easily be acclaimed as a feminist whereas some critics have viewed her as a Muslim or Islamic feminist which is nothing but an immature attempt to underestimate her genius. It was true that she was brought up in an Islamic cultural milieu and tried to educate the then lagged behind Muslim girls which, the critics probably cogitated as the main aim of her life overlooking the universality of women＇s problems she dealt with and her non-sectarian outlook of life. In fact, she sprang up beyond the limitations the society placed upon her and was boldly vocal about the freedom of women irrespective of their distinctive faiths and social customs. This paper, therefore, aims at exploring Rokeya＇s Istrijatir Abanati （Woman＇s Downfall） （1903） with a view to showing her firm determination, endeavors, and voice to emancipate women, and advocating her as a concerned feminist.

A Comparative Study on Hydrodynamic Performance of Double Deflector Rectangular Cambered Otter Board

In the present work,the hydrodynamic performance of the double deflector rectangular cambered otter board was studied using wind tunnel experiment,flume tank experiment and numerical simulation.Results showed that the otter board had a good hydrodynamic performance with the maximum lift-to-drag ratio(K_(MAX) = 3.70).The flow separation occurred when the angle of attack(AOA) was at 45?,which revealed that the double deflector structure of the otter board can delay the flow separation.Numerical simulation results showed a good agreement with experiment ones,and could predict the critical AOA,which showed that it can be used to study the hydrodynamic performance of the otter board with the advantage of flow visualization.However,the drag coefficient in flume tank was much higher than that in wind tunnel,which resulted in a lower lift-to-drag ratio.These may be due to different fluid media between flume tank and wind tunnel,which result in the big difference of the vortexes around the otter board.Given the otter boards are operated in water,it was suggested to apply both flume tank experiment and numerical simulation to study the hydrodynamic performance of otter board.

Production-Oriented Approach to Reading： Writing-Oriented Reading Instruction

WORI is the Production-Oriented Approach to reading in the TEFL context of China. It is intended to enhance English learners＇ proficiency in writing and reading. By asking questions to draw learners＇ attention to the professional writers＇ choices concerning organization, development, style, and diction, teachers explicitly guide learners to observe, analyze, study, apperceive, so as to learn about their writing thinking and strategies. By designing a variety of reading-to-write tasks, teachers endeavour to activate learners＇ writing thinking developed in writing-oriented reading activities to have such writing thinking fixed in mind and internalized. The WORI also fosters English learners＇ autonomy of sustaining development in reading, writing, as well as their English learning.

Discussion of the mode of the management in the college students from the perspective of the counselors - the psychological contract

In the colleges and universities, the relationship between the instructors and the students is very close. The counselors carry out the scientific and reasonable management on the life and learning of the students, and the students meet with the problems in their life and learning and exchange and communicate timely with the counselors, which is the process to realize the functions of the counselors. Then the management of the instructors built on the psychological contract is the more perfect, comprehensive, and scientific management mode. This kind of the management mode is not only very conducive to the development of the students, but also conducive to the interaction and communication between the counselors and the students. In a relaxed and harmonious atmosphere, the student＇s development will be more healthy and positive. This paper elaborates and analyzes several aspects in view of the management of the psychological contract of the university counselors.

Study on dynamic model of tractor system for automated navigation applications

This research aims at using a dynamic model of tractor system to support navigation system design for an automati- cally guided agricultural tractor. This model, consisting of a bicycle model of the tractor system, has been implemented in the MATLAB environment and was developed based on a John Deere tractor. The simulation results from this MATLAB model was validated through field navigation tests. The accuracy of the trajectory estimation is strongly affected by the determination of the cornering stiffness of the tractor. In this simulation, the tractor cornering stiffness analysis was identified during simulation analysis using the MATLAB model based on the recorded trajectory data. The obtained data was used in simulation analyses for various navigation operations in the field of interest. The analysis on field validation test results indicated that the developed tractor system could accurately estimate wheel trajectories of a tractor system while operating in agricultural fields at various speeds. The results also indicated that the developed system could accurately determine tractor velocity and steering angle while the tractor operates in curved fields.

Transformative Learning in Language Arts as a Method of Guidance and Counseling

Our voluntary project ran in different groups of adults （healthy, depressed, schizophrenic, and clients with anxiety disorders）. The study is based on analysis of personal counseling experience, where literature was used as a tool to disclose client＇s personal meanings. During our sessions, clients were observed phenomenologically, and their speach was written down. Reflecting on the qualitative data of transformative learning in language arts, we developed techniques for facilitation and disclosure of personal meanings. Grounded theory was used for data generalization： Personal educational insights and its comparison with other researchers＇ theoretical insights were the basis to develop the methodical system for psychological guidance and counseling and to explain it. We revealed that focus on personally important meanings during discussion after literature reading has influence on the mental state of personality and deepens the interactions with the literature art, so we suggest a spiral model to explain the methodical system of our method. Transformative learning in language arts as a method of guidance and counseling can be understood as spiritual motion by spirale. It has three levels： （1） art level （interaction with the literature）; （2） psychology level （counseling）; and （3） art level （interaction with the same peace of literature as in the beginning of the session, poetic summary of the session）. Levels （1） and （3） mean interaction with literature art, but at the third level, this interaction has new quality, because personality has better perception of Self and more ability to connect personal meanings and literature wisdom. At the first level, we have direction from literature to Personality. At the third level, we have direction from the Self （Speaking from Within） to literature. Disclosure of personally important meanings is a key to self-understanding and poetical thinking; our developed methodical system reduces emotional tension and strengthens interconnectedness between inner and outer world and improves poetical understanding. In this paper, the methodical system of transformative learning and guidance is discussed.
