Résumé :

The recently developed magnet-controlled transfer printing is valuable to develop advanced engineering systems due to its ability to tune the interfacial adhesion strength continuously and rapidly. A three-dimensional analytical model based on the energy method is developed for the magnet-controlled transfer printing. The predicted interfacial adhesion strengths agree well with experiments. A scaling law is established for the normalized interfacial adhesion strength, which depends on only four non-dimensional parameters: the normalized stamp size, the normalized stamp height, the normalized w

Résumé :

Piezoelectric three-dimensional inkjet printing has been used to manufacture heterogeneous objects due to its high level of flexibility. The materials used are non-Newtonian inks with complex rheological properties, and their behavior in the context of inkjet printing has not been fully understood: for example, the fact that the shear-thinning viscosity affects the droplet generation. Therefore, a control strategy coping with shear-thinning behaviors is needed to ensure printing consistency. In this paper, a novel model-based approach is presented to describe the shear-thinning ink dynamics in

Abstract As a popular rapid manufacturing technology, three-dimensional printing (3D printing) has been widely adopted in medical, automotive, aerospace, construction and other industrial fields. The stereo lithography apparatus (SLA) is an effective 3D printing method for ceramic printing. However, shrinkage from monomer to polymer and laser stress wave cause residual stress in the formed parts during SLA. Serious quality defects including cracks, warpage and deformation caused by residual stress have remained to be a problem. Basically, the laser stress wave plays an important role in the ge

In some applications of piezoelectric three-dimensional inkjet printing, the materials used are power-law fluids as they are shear thinning. Their time-varying viscosities affect the droplet formation, which is determined by the volume flow rate at the nozzle outlet. To obtain a fine printing effect, it is necessary to present a driving waveform design method that considers the shear-thinning viscosities of materials to control the volume flow rate at the nozzle outlet, which lays the foundation for the single and stable droplet generation during the printing process.

Résumé :

It has been challenging for city school pupils to learn about insects, given the lack of live insects. To overcome this challenge, the objective of this study is to propose the use of emerging digital media, namely three-dimensional printing (3DP) technologies, to create reusable, fake, “live” insects. In this study, we designed two 3D-printed pedagogical aids to support elementary entomology. The first aid was a set of cards showing photos of the 3D-printed insect prototype, which could help the learners in close observation of the insect body’s regions and parts, and the second 3D-printed ai

Résumé :

Compression garments apply garment pressure to suppress growth and flatten hypertrophic scars caused by serious burns. In order to reduce the pain caused by a trial-made compression garment for burn patients, one of the most studied parts of the human body, the arm, was selected as the research object, and the characteristics of an arm model that could be used for compression sleeve design and garment pressure measurement were studied. Five human arm models were made based on three-dimensional-printing technology, and then a compression sleeve was made based on Laplace’s law. After that, the g

Résumé :

For the Ukrainian population, there are factors surrounding the choices and preferences one must consider when changing permanent residence. Smart residential areas should be built according to Ukrainian legislation and global innovations, which would reduce administrative dislocations, the load on megalopolises, and negative anthropogenic impacts, and should be based on the increase in energy efficiency and reducing waste. We analyzed the core principles of designing smart residential areas and concluded that constructing cutting-edge residential areas should involve private investments in or

Résumé :

The emergence of new technologies such as the Internet of Things, big data, and advanced robotics, together with risks such as climate change, rising labour costs, and a fluctuating economy, are challenging the current UK manufacturing model. In this paper, business models for re-distributed manufacture (RdM) are developed using anIDEF (Icam DEFinition for Function Modelling) description to serve as a guide for the implementation of the RdM concept in the consumer goods industry. This paper explores the viability of a re-distributed business model for manufacturers employing new manufacturing

Résumé :

AbstractPlasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-based metamaterials, have attracted progressively increasing attention in recent years because of the ease of fabrication and unprecedented control over the reflected or transmitted light while featuring relatively low losses even at optical wavelengths. Among all the different design approaches, gap-surface plasmon metasurfaces – a specific branch of plasmonic metasurfaces – which consist of a subwavelength thin dielectric spacer sandwiched between an optically thick metal film and arrays of metal s

Résumé :

There is plenty of research describing remanufacturing (reman) as the ultimate form of recycling. However, few studies have shown how standards that provide universally accepted definitions and practices can shift towards digitization and how digital technology can act as a catalyst for digital reman. Furthermore, there is no clear direction as to why and how standards and digital technology should work together in reman. Only minimal research (one article from the SCOPUS database) has explored the intersection of these three areas: reman challenges, standards, and digital technology. Many cha

The circular business model (CBM) is one of the main building blocks of circular economy (CE), and recycling is one of the main strategies for achieving it. CBM literature is currently evolving, and recycling-oriented discussion has been found in a scattered manner. This review article aims to identify critical components of the recycling-focused business model in CE and evaluate potential business and research opportunities in the area.

Résumé :

AbstractThis article engages with a key question raised by feminist legal scholars from the east to the west: whether women should or should not engage in rights strategies? Are rights systematically exercised to reproduce patriarchal, dominant sites of justice, or do rights constitute a multiple and relational force which may transform sites of justice? The experience of women’s engagements with law in South Asia has created a diversity of critical legal knowledge and scholarship reflecting the pluralism of both women’s identities and needs based on caste, religion, class and sexuality across

One sentence in the Prologue of the Law of Jutland (1241) has caused much scholarlydiscussion since the nineteenth century. Did it say that “the law which the king givesand the land adopts, he [i.e. the king] may not change or abolish without the consentof the land, unless he [i.e. the king] is manifestly contrary to God” – or “unless it [i.e.the law] is manifestly contrary to God”?

Abstract Polymer three-dimensional (3D)-printing has been commercialized rapidly during recent years; however, there remains a matter of improving the manufacturing speed. Screw extrusion has a strong potential to fasten the process through the simultaneous operation of the filament production and the deposition. This paper develops a control algorithm for screw extrusion-based 3D printing of thermoplastic materials through an observer-based output feedback design.

   Historically the impact of the printing press on Western culture is a truism. Print gave rise to the mass reproduction and circulation of information with wide reaching consequences in all fields: political, social, and economic. An aspect that this paper wishes to focus on is that this moment also saw the birth (and necessity) of copyright legislation, to administer and protect this new found ability to package and disseminate text. The term copyright itself, used freely in debates surrounding contemporary topics such as iTunes, DVD piracy, and file-sharing, is not only s
