Abstract The integration of augmented reality and drones allows past and future landscapes to be visualized from an aerial perspective. However, these visualizations still suffer from the occlusion problem, where the three-dimensional (3D) virtual model displayed in the real world is in front of a real-world object. Currently, city digital twins are essential for the sustainable development of cities and the development of detailed 3D models of cities. By visualizing the city digital twin, augme

Architecture, engineering, and construction projects need to be promoted in harmony with the natural environment and with the aim of preserving people’s living environment. At the planning and design stage, decision-makers and stakeholders share and assess landscape images during and after construction in order to avoid as much uncertainty as possible when performing environmental impact assessment. Given the lack of a standard visualization method for future landscapes that do not yet exist, mi

The mechanism of amyloidosis of amyloid beta (1-42) (Abeta (1-42)) was investigated by the well-defined glycocluster interface. We prepared monovalent, divalent, and trivalent 6-sulfo-N-acetyl-d-glucosamine (6S-GlcNAc) immobilized substrates. The morphology and secondary structure of Abeta (1-42) aggregates on the substrates were investigated by dynamic-mode AFM and FTIR-RAS. Abeta (1-42) interactions with multivalent sugars were evaluated by surface plasmon resonance, and the cytotoxicity of Ab

In the digital age, physical models are still used as major tools in architectural and urban design processes. The reason why designers still use physical models remains unclear. In addition, physical and 3D virtual models have yet to be differentiated. The answers to these questions are too complex to account for in all aspects. Thus, this study only focuses on the differences in spatial understanding between physical and virtual models. In particular, it emphasizes on the perception of scale.

To improve indoor thermal environment, it is necessary to promote a lean design process, so forecasting and consensus building by experiment and numerical calculation from the design stage have become essential. Rapid advances in software and hardware allow feedback to be generated on novel design alternatives, rather than relying on simulation results based on past designs. However, this concept has not been fully verified. Therefore, this study presents an integrated design tool which consists

When Telenomus nawai Ashmead or Trichogramma ostriniae Pang & Chen (Hymenoptera: Trichogrammatidae) was inoculated into intact egg masses of Spodoptera litura (Fabricius) that were covered with a scale-hair layer, T. nawai emerged from 76% of the eggs, while emergence of T. ostriniae was from only 3% of the eggs. When the hair layer was removed before inoculation, the rate by the latter increased to 21%. These observations confirmed that the hair layer effectively protects S. litura egg masses f

Information extracted from aerial photographs is widely used in the fields of urban planning and design. An effective method for detecting buildings in aerial photographs is to use deep learning to understand the current state of a target region. However, the building mask images used to train the deep learning model must be manually generated in many cases. To overcome this challenge, a method has been proposed for automatically generating mask images by using textured three-dimensional (3D) vi

The need for visual landscape assessment in large-scale projects for the evaluation of the effects of a particular project on the surrounding landscape has grown in recent years. Augmented reality (AR) has been considered for use as a landscape simulation system in which a landscape assessment object created by 3D models is included in the present surroundings. With the use of this system, the time and the cost needed to perform a 3DCG modeling of present surroundings, which is a major issue in
