The feature map obtained from the denoising autoencoder (DAE) is investigated by determining transportation dynamics of the DAE, which is a cornerstone for deep learning. Despite the rapid development in its application, deep neural networks remain analytically unexplained, because the feature maps are nested and parameters are not faithful. In this paper, we address the problem of the formulat...

The 21st century will see a renewed focus on intermodal freight transportation driven by the changing requirements of global supply chains. Each of the transportation modes (air, inland water, ocean, pipeline, rail, and road) has gone through technological evolution and has functioned separately under a modally based regulatory structure for most of the 20th century. With the development of con...

In recent years, studying and predicting mobility patterns in urban environments has become increasingly important as accurate timely information on current future vehicle flows can successfully increase the quality availability of transportation services (e.g., sharing services). However, number incoming outgoing vehicles for different city areas is challenging due to nonlinear spatial tempora...

We demonstrate a rice leaf-like hierarchically textured polymer fiber array for anisotropic non-wetting surfaces. To provide superhydrophobicity in addition to the anisotropic behavior, fiber surfaces are spray coated with organically modified silica nanoparticles. The resulting micro/nano hierarchically structured fiber surfaces demonstrate anisotropic non-wetting properties. We designed vario...

Although artificial micromotors with unconventional shapes are emerging as a powerful tool in various applications, little research has been undertaken to clarify their propulsion mechanism, especially how the shape effect alters bubble dynamics and hydrodynamic flows. In this study, we fabricated two types of bowl-shaped investigate distinct due concave convex surfaces, by coating platinum (Pt...

To the Editor — Detailed analysis of volcanic materials1 allows the study of eruptions that have not been witnessed directly. Rotella et al.2 undertake the challenge of interpreting submarine volcaniclastic deposits around Macauley Volcano, part of the Kermadec Arc in the southwest Pacific Ocean. They propose a ‘Tangaroan’ eruption style, based on the textural characteristics of dredged pumice ...

Resource sharing and allocation are important coordination problems in most processes and organizations. They are especially critical in transportation systems, where the resource to be shared and allocated is the space through which various vehicles move and the problem is ensuring that vehicles do not conflict in their use of the space—that is, that they do not collide. Transportation systems...

Standardised cargo units, such as the container, have been a great technical invention for improving the efficiency and effectiveness of international transport chains. Maybe the biggest advantage of these units comes from their modularity. Modularisation can also be seen as a prerequisite for future transport systems while integrating the physcial cargo flows and related information more close...

In the well-known Braess paradox [D. Braess, Unternehmenforschung 12, 258 (1968)], the addition of a new route in a specific congested transportation network made all the travelers worse off in terms of their individual travel cost (time). In this paper, we consider the hypothesis that, in congested networks, the Braess Paradox may “disappear” under higher demands, and we prove this hypothesis ...

Abstract The impact origin of the Early Cretaceous (140.82 ± 0.51 Ma) 20‐km diameter Dellen structure was proven in late 60s based on discovery planar deformation features (PDFs) quartz grains. Although decades have passed, impactites found from crater not received much attention. Thus, this study provides a detailed petrological and mineralogical description Dellen. Impactites were classified ...
