3D printers inspire user creativity by allowing them to design and create actual 3D objects. Unfortunately, printers often require long printing time and waste a lot of materials. Various techniques have been proposed to alleviate the issues, such as ...

Weakly-supervised temporal action localization aims to identify and localize action instances in untrimmed videos using only video-level action labels. Due to the lack of frame-level annotation information, correctly distinguishing foreground and ...

Additive manufacturing (AM) allows to produce parts layer by layer from an STL file. It is then possible through this technology to obtain customized geometries and complex shapes at a lower cost. However, these shapes pose problems of defect ...

• Proper airway management education for patients with obesity is expected to rise.
• Trainees rarely perform difficult airway management in actual clinical settings.
• Existing simulators suffer from high prices, limited access, and ...

Proper airway management during emergencies can prevent serious complications. However, cricothyroidotomy is challenging in patients with obesity. Since this technique is not performed frequently but at a critical time, ...

Nowadays, designers and engineers rely on specific manufacturing guidelines to bring quality products to market with minimum time and error. Design for Additive Manufacturing (DfAM) is one of these guides adapted to Additive ...

• Optimizing production parameters to improve the design of the additive manufactured part in the industrial field.

The railway point machine is a significant element of railway signalling equipment that keeps trains running safely. Railway point devices are actuators that move switchblades to reroute trains in different directions. The features are manually designed ...

As the 3D printing polymer material extrusion process is moving beyond niche markets and into large-scale manufacturing, still commercial systems employed by this process work in an open-loop environment where no feedback or control solution is ...

3D printing is based on layered manufacturing, where the layers are printed consecutively in increasing height order. In Fused Depositing Modeling (FDM), the printing head may travel without extruding material between separated “islands” of the sliced ...

More than 600 million people worldwide have any disability, with about 80% of them living in low-income countries, and those in need of prosthetics represent 0.5% of the total world population, while a wide majority of that population cannot ...

4D printing is an emerging field of fabrication garnering interest from the HCI community in its potential applications. In this work we present a hands-on exploration of the hybrid design space for 4D printing which makers can utilize to create their ...

Oil palm (Elaeis guineensis Jacq.) is of the most profitable and widespread commercial high tree crops in the tropical world, typically in Southeastern Asia. The present study aims to provide a brief but broad overview of different ...

A multichannel frequency-division-multiplexing (FDM) system consisting of a one-dimensional photonic star waveguides (SWGs) structure is studied theoretically. This SWGs system exhibits large electromagnetic bandgaps that originate both from the ...

4D printing is a new technique for human-computer interaction to create self bending and actuating interfaces, leveraging the properties of 3D printed materials for shape change over time, triggered by external factors such as heat. Given the ubiquity ...

Continuous multi-axis printing has drawn more and more attention owing to its unique advantages of eliminating the need of support (at least in theory) when printing complex models with overhang features and significantly reducing the ...

• A new curved-layer decomposition method based on ellipsoidal surface is developed.

The paper proposes the structure of a typical training program for implementation in online format with the inclusion of independent engineering work of a student on the basis of a home laboratory. Recommendations for home laboratory equipment are made ...

Additive manufacturing is typically conducted in a layer-by-layer fashion. A key step of the process is to define, within each planar layer, the trajectories along which material is deposited to form the final shape. The direction of these trajectories ...

This paper presents a technique for 3D printing firm inflatables with consumer-grade fused-deposition modeling (FDM) 3D printers and flexible filaments. By printing bridges inside the inflatable to tie its walls, internal tethers can retain the shape of ...

We present a method to design non-planar layered print paths for robotic fused deposition modeling (FDM) printing of single-shell surfaces. The advent of robotic arms has created great potential in the 3D printing industry for the realization of non-...

The magnetohydrodynamic mixed convection boundary layer flow in the presence of aligned magnetic field along a vertical cylinder is considered. Particular attention is paid to investigate how the buoyancy effects of thermal diffusion combine with joule ...

In this study, the steady, laminar, and fully developed magnetohydrodynamic (MHD) flow is considered in a long channel along with the z-axis under an external magnetic field which is perpendicular to the channel axis. The fluid velocity u and the ...
