Elucidation of the joining and interface mechanism of lightweight difficult-to-weld materials joined by explosive impact force

Explosive welding can be used to join materials using controlled explosions, creating materials with desirable properties. Assistant Professor Mami Mihara-Narita, Department of Physical Science and Engineering, Nagoya Institute of Technology (NIT), Japan, is exploring the potential of joining technology by explosive welding for the multi-materialism of lightweight materials such as magnesium alloy and aluminium alloy and evaluating their characteristics for practical use. She hopes that her work will contribute to the weight reduction of transportation materials, as well as benefiting transportation equipment and clean energy materials. Mihara-Narita is collaborating closely with Professor Yoshimi Watanabe and Associate Professor Hisashi Sato from NIT, and Dr Yasumasa Chino and Dr Hisashi Mori from the National Institute of Advanced Industrial Science and Technology (AIST and UACJ corporation) in this work. The team is also performing characteristic analysis of explosive welded materials, using a transmission electron microscope to observe interfacial microstructure. The researchers are also evaluating joint strength by shear test, measuring hardness and micro deformation by nanoindentation method and measuring residual stress by X-ray diffraction and neutron diffraction method. In addition they are investigating fatigue strength in order to ensure materials are suitable for use in transportation equipment. Fatigue strength will continue to be a key focus for the researchers moving forward, and they will also be performing data analysis of their data on explosive welding conditions, metallographic structure and various properties of explosive welding clad material.

The Energy, Information, Robotics, and Industrial Revolution [Students and Young Professionals News

While the IEEE Industrial Electronics Society (IES) is celebrating its 70th anniversary, the energy, information, robotics, and industrial revolution is speeding up. It seems that soon everyone in the world will have access to electricity. The electric power supply is a common factor for electrical and electronics devices. It does not matter if we are considering electrifying a Honduran primary school or automating a Japanese robotic factory—without a reliable, flexible, environmentally friendly energy source, modern education and industrialization is not possible. Therefore, one role of the IES is to attract as many new engineers as possible. We need to show girls that engineering is as attractive as other study fields. We must propose a discussion platform for undergraduates, postgraduates, and young professionals from industry. This kind of platform was presented at the IES 70th Anniversary Joint Forum of Women in Engineering (WiE) and Students & Young Professionals (S&YP) at the 2021 International Symposium on Industrial Electronics (ISIE2021)-Kyoto online conference by IES Vice President for Planning and Development, Prof. Makoto Iwasaki, Nagoya Institute of Technology, Japan.

Using Decision Support System to Enable Crowd Identify Neighborhood Issues and Its Solutions for Policy Makers: An Online Experiment at Kabul Municipal Level

Planning a city is a systematic process that includes time, space, and groups of people who must communicate. However, due to security problems in such war-ravaged countries as Afghanistan, the traditional forms of public participation in the planning process are untenable. In particular, due to gathering space difficulties and culture issues in Afghanistan, women and religious minorities are restricted from joining male-dominated powerholders’ face-to-face meetings which are nearly always held in fixed places called masjids (religious buildings). Furthermore, conducting such discussions with human facilitation biases the generation of citizen decisions that stimulates an atmosphere of confrontation, causing another decision problem for urban policy-making institutions. Therefore, it is critical to find approaches that not only securely revolutionize participative processes but also provide meaningful and equal public consultation to support interactions among stakeholders to solve their shared problems together. Toward this end, we propose a joint research program, namely, crowd-based communicative and deliberative e-planning (CCDP), a blended approach, which is a mixture of using an artificial-intelligence-led technology, decision-support system called D-Agree and experimental participatory planning in Kabul, Afghanistan. For the sake of real-world implementation, Nagoya Institute of Technology (Japan) and Kabul Municipality (Afghanistan) have formed a novel developed and developing world partnership by using our proposed methodology as an emerging-deliberation mechanism to reframe public participation in urban planning processes. In the proposed program, Kabul municipality agreed to use our methodology when Kabul city needs to make a plan with people. This digital field study presents the first practical example of using online decision support systems in the context of the neighborhood functions of Gozars, which are Kabul’s social and spatial urban units. The main objective was to harness the wisdom of the crowd to innovative suggestions for helping policymakers making strategic development plans for Gozars using open call ideas, and for responding to equal participation and consultation needs, specifically for women and minorities. This article presents valuable insights into the benefits of this combined approach as blended experience for societies and cities that are suffering long-term distress. This initiative has influenced other local Afghan governments, including the cities of Kandahar and Herat as well as the country’s central government’s ministry of urban planning and land, which has officially expressed its intention to collaborate with us.

Research on the formulation and effects of teaching methods that enhance learning motivation in Arabic language

Although Arabic language learners and opportunities for learning the language gradually increased in Japan from 1925 when formal Arabic education began until the beginning of the 21st century, there is little research on Arabic language teaching and learning. To fill this gap, Akiko Sumi, Kyoto Notre Dame University, Japan, is working to better understand the learning environment of the Arabic language and social characteristics of Arabic language learners in Japan. Her ultimate goal is to increase autonomous motivation for Arabic language learning among learners in Japan. Akiko Sumi specialises in Arabic literature and language and is collaborating with Professor Katsunori Sumi of the Graduate School of Engineering, Nagoya Institute of Technology, Japan, who specialises in applied psychology. Together, the two researchers are working to develop a new hypothetical model and refine instructional methods for teaching Arabic language. A psychological element of this work involves assessing the psychological characteristics of Arabic language learners in Japanese universities. The researchers also held an intensive Arabic language camp in Rurikei, Kyoto, at which around 100 students were offered an appropriate environment to support and satisfy autonomy, competence, and relatedness. The researchers are investigating Arabic language learning as part of foreign language learning and second language acquisition, with a keen focus on learning motivation as this is a key factor influencing language learning and teaching.

Electron Field Emission from Multiply-Stacked Si Quantum Dots Structures with Graphene Top-Electrode

Introduction Electron field emission from Si-based nanocrystals has been stimulated considerable interest because electron emission devices are expected to be used for various applications [1, 2]. In our previous work, we have demonstrated electron field emission from multiple-stacked Si-quantum-dots (Si-QDs) structures with ultrathin Au top electrodes under biases of 6V and over, in which electric field concentrates on the upper dot layers [3]. To reduce electron scattering in top electrodes, we fabricated the multiple stacked Si-QDs structures with single layer graphene top electrodes and evaluated their electron emission properties. Experimental After conventional wet chemical cleaning steps, n-type Si(100) wafers were oxidized at 1000 °C in dry O2 to form ~3.0 nm thick SiO2. After that, Si-QDs with an areal dot density as high as ~4.7×1011 cm−2 and an average dot size of ~4.5 nm were formed on SiO2 by low pressure chemical vapor deposition (LPCVD) using pure SiH4, followed by thermal oxidation to cover the surface of the dots with ~1.5 nm-thick SiO2. By repeating such a process sequence, 11-fold stacked Si-QDs layers were formed. Single layer graphene was formed on a Cu foil by solid-source LPCVD using Poly-styrene. After spin coating poly methyl methacrylate (PMMA) on the graphene, the Cu film and residual Fe were removed by dipping in the Fe(NO3)3·9H2O solution and nitric acid solution (HNO3: H2O = 1:5), respectively. After that, PMMA/graphene was transferred on the multiple stacked Si-QDs layers. Subsequently, the PMMA was removed by dipping in acetone and IPA. We also fabricated ~10 nm-thick Au films as top electrodes on the 11-fold stacked Si-QDs by electron beam (EB) evaporation as a reference. Finally, Al films were formed as bottom electrodes by thermal evaporation. Results and Discussion When forward bias (|V s|) exceeds ~6.0 V, electron emission current (I e) from the multiple stacked Si-QDs with the graphene top electrode appears. In addition, with an increase in the |V s|, the I e was exponentially increased as in the case of the Au top-electrodes. It is interesting to note that the I e for the sample with the graphene top electrode was larger than that for the sample with the Au top electrode although the sample current (I s) was suppressed by using graphene as the top electrode (Fig.1). This result implies reduction of electron tunneling current, which can be interpreted in terms of density-of-state difference between the graphene and Au. In addition, an effective contact area of the graphene might be smaller than that of a designed value. We also summarized emission efficiencies as a function of |V s|, as shown Fig. 2. Obviously, in both cases, with an increase in the |V s|, emission efficiencies were increased exponentially. Notice that, by using the graphene top electrode, the emission efficiency was increased by a factor of ~100 compared with that of the sample with the Au top electrode under the same |V s|. This result indicates that, by using a single layer graphene as a top electrode, electron emission efficiency can be enhanced by the reduction of electron scattering within the top electrode. Conclusion The graphene top electrode plays a role in high efficiency electron emission from the stacked structures of Si-QDs due to the reduction of electron scattering within the top electrode.

Autonomy in Learning and First-year Curriculum for Engineering Education for Value Creation

Nagoya Institute of Technology launched a new education program, called Creative Engineering Program (CEP), which aims to produce engineers with value-creation ability and broader views and is a six-year integrated course with undergraduate and graduate courses. This article introduces structure of CEP’ s curriculum and systems to support student learning in CEP. We discuss the learning processes of students in CEP by referring the theory of self-regulated learning introduced in the research by B. J. Zimmerman6). We show that there are multiple learning processes in CEP which are characterized by the elements of self-regulated learners. We also reveal that the learning process about goal setting conducted in the first-year students in CEP has an important role for the entire program of CEP.

Practical Papers, Articles and Application Notes

With the advancements of robotic technology, robots have been widely deployed in factory automation and health care. One of the major applications of robots in health care is the myoelectric artificial hand. It consists of a myoelectric signal detector connected to a motor-controlled artificial hand driving unit by wires. In the near future, they will be connected wirelessly for convenience but this may pose an EMI risk to the normal operation of the artificial hand. One possible source of EMI is the electrostatic discharge (ESD) from a charged human body. As the malfunction of a myoelectric artificial hand due to ESD has a direct impact on human life, high immunity performance is required. Yasuhiro Morinaga, Keinosuke Nagai, Jianqing Wang and Daisuke Anzai from Nagoya Institute of Technology, Japan, look into this impact and propose design improvements to enhance the immunity of the myoelectric artificial hand against ESD in the paper “Impact of Electrostatic Discharge on Wearable Robotic Hand and Improvement of Immunity Performance by Wireless Control.”

Hybrid numerical tool for nonlinear analysis of piled rafts

This paper presents a hybrid numerical tool for nonlinear piled rafts analysis. The nonlinear pile behavior is represented by a hyperbolic function, which intends to simulate the variation in pile stiffness during loading. As the nonlinear behavior of piles is restricted to a very thin zone next to the pile interface, only the linear elastic effects are considered in the interaction factors between foundation elements. The influence of using Kirchhoff or Mindlin plate finite elements to model the raft is discussed. The code was compared to other well tested numerical tools, three model tests on piled raft foundation carried out at the Nagoya Institute of Technology (NIT) and also a well-known case of piled raft foundation (Hyde Park Cavalry Barracks in London). The code showed a very good agreement, proving its consistency and potential for use in piled raft analysis and design.

Web-based environment for user generation of spoken dialog for virtual assistants

In this paper, a web-based spoken dialog generation environment which enables users to edit dialogs with a video virtual assistant is developed and to also select the 3D motions and tone of voice for the assistant. In our proposed system, “anyone” can “easily” post/edit contents of the dialog for the dialog system. The dialog type corresponding to the system is limited to the question-and-answer type dialog, in order to avoid editing conflicts caused by editing by multiple users. The spoken dialog sharing service and FST generator generates spoken dialog content for the MMDAgent spoken dialog system toolkit, which includes a speech recognizer, a dialog control unit, a speech synthesizer, and a virtual agent. For dialog content creation, question-and-answer dialogs posted by users and FST templates are used. The proposed system was operated for more than a year in a student lounge at the Nagoya Institute of Technology, where users added more than 500 dialogs during the experiment. Images were also registered to 65% of the postings. The most posted category is related to “animation, video games, manga.”The system was subjected to open examination by tourist information staff who had no prior experience with spoken dialog systems. Based on their impressions of tourist use of the dialog system, they shortened the length of some of the system’s responses and added pauses to the longer responses to make them easier to understand.
