    Abstract

    In this research paper, we propose an unsupervised framework for feature learning based on an autoencoder to learn sparse feature representations for EEG-based person identification. Autoencoder and CNN do the person identification task for signal reconstruction and recognition. Electroencephalography (EEG) based biometric system is vesting humans to recognise, identify and communicate with the outer world using brain signals for interactions. EEG-based biometrics are putting forward solutions because of their high-safety capabilities and handy transportable instruments. Motor imagery EEG (MI-EEG) is a maximum broadly centered EEG signal that exhibits a subject’s motion intentions without real actions. The Proposed framework proved to be a practical approach to managing the massive volume of EEG data and identifying the person based on their different task with resting states.

    Abstract

    Aluminium (Al) and magnesium (Mg) alloys are extensively used in the automobile sector because of their high strength-to-weight ratio, excellent castability, low density and simplicity of recycling. Al-Mg structures that automotive uses have a big chance of lowering their weight. Although there is a significant opportunity for substantial cost reduction, the use of magnesium in aluminium structures remains restricted. This study aims to weld 3 mm-thick rolled sheets of AA6061 Al and AZ31B Mg alloy using the cold metal transfer (CMT) arc welding process. Three different filler wires (ER1100, ER4043, and ER5356) were used in the experiment. In this article, the mechanical and microstructure characteristics of Al/Mg dissimilar joints manufactured by CMT are evaluated and discussed in depth. Optical microscope (OM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction were all used to analyse the CMT-welded Al/Mg dissimilar joints. Of the three filler wires used, ER4043 (Al-5%Si) filler wire yielded defect-free sound joints due to the presence of Si, which improves the flow ability of molten filler during welding. The Al/Mg dissimilar weld still produced the Mg-rich intermetallic (IM) Al12Mg17 and the Al-rich IM Al3Mg2. The surfaces of the fractured area of the CMT-welded Al/Mg dissimilar joints revealed the presence of the Mg-rich intermetallics (Al12Mg17), which is responsible for the decrease in tensile strength. The reduction of intermetallics, particularly of Mg-rich intermetallics (Al12Mg17) is important for improving joint strength.

    Highlights

    • Cold metal transfer (CMT) arc welding was used to control the Al-Mg-rich intermetallics in the Al/Mg dissimilar joints.
    • The microstructure, morphology and phase composition of the welded joints were studied by OM, SEM, TEM, EDS and XRD.
    • The weld metal and AL substrate are joined with a strong interface, while the weld metal and Mg substrate are joined with an epitaxial solidification area where the intermetallic compounds of Mg2Al3, Mg17Al12 and Mg2Si are generated.
    • The weld metal on the Mg side experienced a brittle fracture, with a continuous distribution of Mg2Al3, Mg17Al12 and Mg2Si.

    Explanation of Research in Layperson’s Terms

    Al and Mg alloys are extensively used as light metals in engineering due to their advantageous characteristics, including high strength-to-weight ratio, cheap casting costs, low density, excellent machinability, and simple recyclability. Often, each of these materials fails to meet the criteria for lightweight buildings. Consequently, there is a high need for a significant quantity of Al/Mg hybrid structures in many industrial sectors with a particular emphasis on the automotive industry. Choosing the appropriate filler material for joining Al and Mg is crucial for creating robust weldments. The main difficulty in welding dissimilar metals like aluminium and magnesium lies in the formation of inflexible and brittle intermetallic compounds (IMCs) like Mg2Al3 and Mg17Al12, which severely affect the joint’s strength. When it comes to melting points, magnesium is at 650°C and aluminium is at 660°C. Based on the Mg-Al binary phase diagram, the compounds Mg2Al3 and Mg17Al12 can be produced at 450 and 437°C by eutectic reaction. Hence, the primary challenge in Al/Mg dissimilar welding is effectively suppressing the growing number of IMCs. Similarly, minimising energy input and utilising the appropriate chemistry of wire are the primary methods for decreasing the formation of IMCs and improving joint strength.

    CMT is an advanced arc welding process which comes under controlled short circuiting transfer mode. The CMT welding cycle consists of two phases, i.e. the arcing phase and short circuit phase. In arcing phase, the filler wire gets melted and it forms as a droplet at the tip of the filler wire. In short circuiting phase, the droplet bridges the gap between the electrode and the weld pool. Once the short circuiting takes place, the filler wire gets retracted backward due to the retraction force and the droplet is detached from the filler wire. In conventional short circuiting transfer mode, the electromagnetic pinch force assists in detaching the droplet from the filler wire and thereby high heat input is produced by means of the short current. Where as in CMT short circuit transfer mode, the welding current is decreased to a lower value whenever a short circuit signal is sensed by the power source and the droplet gets separated from the filler wire with the help of the retraction force that is generated during the backward movement of the filler wire. Finally, the heat input is reduced to a lower value with this metal transfer mode. So, the CMT arc welding process was used to join the 3 mm-thick rolled sheets of AA6061 Al and AZ31B Mg alloy dissimilar materials. This article details the microstructural characteristics of an Al/Mg dissimilar joint. The CMT process controlled IMCs in the Al/Mg dissimilar joint and increased weld metal hardness compared to base metal.

  • Tracing a Translator’s Journey: An Interview with V Ramaswamy March 13, 2024

    bidisha-pal-paper

    A translated work must retain the essence and flavour of regional culture and locales. A good translator tries to reproduce the particularities that are ingrained within the texts. On this note, Dr Bidisha Pal, Assistant Professor from the Department of Literature and Languages, has published a paper, “Delving into a Translator’s Journey of Translating Marginalised Voices of Bengal: An Insightful Discussion with V Ramaswamy” in Meta Journal des traducteurs Translators’ Journal. This research revolves around a discussion with the well-known translator V Ramaswamy, a noted name in Bengali Dalit literature and translation. Ramaswamy shares his thoughts on working on the translation projects that he enjoys doing and that establish the cause of the marginalised people of Bengal.

    Abstract

    In this interview discussion with Bidisha Pal and Md. Mojibur Rahman, translator V Ramaswamy focuses on the journey of his translation and tryst with the marginalised Dalit voice(s) in Bengal. He speaks about the writings that propel him to choose translating and to carry voice(s) beyond the Bengal arena, thus dissolving language barriers. The deliberate choice to translate various pieces representing various periods acts as a witness to his existence as an independent translator. According to him, translation is also a source of healing to deal with a tragic past and the complicacies that life often presents to him. He shares his experience translating Subimal Mishra, the powerful poet who speaks for marginalised people. Ramaswamy, as he states in the interview, makes a vow to translate Mishra’s whole writing career. He talks about translating Manoranjan Byapari, a Bengali Dalit prize-winning author and political persona who has also championed the Dalit cause in Bengal, Adhir Biswas, the story-writer and publisher of a publishing house in Kolkata Gangchil that publishes writings by those literary personas who do not fall, as such, into the category of the mainstream, Bangladeshi writer Shahidul Zahir whose revolutionary voice and zeal reverberate in the literary world of Bangladesh, as well as Ansaruddin, a writer and farmer by profession whose works Ramaswamy is currently translating. Despite not being a part of the literary world, Ramaswamy has built an intense connection with literature and has gradually become part of the world. For him, translation is something that has to remain faithful to the source text, especially if people are doing literary translation.

    Practical implementation/social implications of the research

    The research contains elements that are connected with the values of the society. It discusses the nuances of translation of the writings of marginalised people, which contain many unforeseen truths of society, and depicts the struggles for the existence of the people. The translator is doing a commendable job compiling the writing thorough translation that will act as a bridge to the unfamiliar audience who could feel connected with the marginalised people.

    Dr Bidisha aims to publish many more articles in the diverse interdisciplinary fields of literature, edit books, and attend conferences.
