The Phased-Array L-Band SAR (PALSAR) aboard the Advanced Land Observing Satellite (ALOS) is capable of globally acquiring fully polarimetric data. In order to confirm ability L-band synthetic aperture radar (SAR) investigate sea ice before ALOS launch, we conducted a field experiment using an airborne Polarimetric and Interferometric (Pi-SAR) in Sea Okhotsk 1999. This paper presents analyzed results data acquired that experiment. extracted parameters several types suggested coherences phase...

Asian cities are unique, where people may need more than just walking; however, the walkability research in a local context has received less attention. This paper analyses walking needs and influential factors of behavior cities. A comparative analysis Bangkok Nagoya is presented, taking into account characteristics street design development. Street evaluation experiments various streets conducted through 360-degree videos. The factor indicate that both can be considered two levels, but...

Spatial light modulators (SLMs) with submicron-size pixels are promising devices for use in wide-viewing-angle glasses-free holographic 3D displays. In accordance estimations, an SLM 1 μm pitch can display images over viewing angles of 30 deg. the present work, we have studied magneto-optic SLMs (MOSLMs) displays that driven by thermomagnetic recording. Amorphous TbFe films were used as a material. The MOSLM 800 nm diameter array displayed images. These results demonstrated MOSLMs promise

To investigate the possibilities of using dual-frequency, multipolarization synthetic aperture radar (SAR) data to monitor sea ice, we derived relationship between various polarization characteristics and physical parameters ice. We discuss frequency backscattering coefficients ice then characterize its thickness by comparing corresponding coefficient for each with first propose a methodology classifying sea-ice types polarimetric decomposition technique, before an estimation SAR data....

Excessive motorisation, resulting from the vicious cycle of car-oriented road development and car-reliant land development, significantly deteriorates walking environments, causing traffic safety problems, damaging city-centre vitality, hindering sustainable mobility. Many Asian cities face these issues, as a result, it is often difficult for their street users to experience higher level needs, such comfort attractiveness, in daily environments. Without experiences, may have difficulty...

Recently, deep learning techniques, specifically semantic segmentation, have been employed to extract visual features from street images, a dimension that has received limited attention in the investigation of connection between subjective and objective road environment perception. This study is dedicated exploring comprehending factors influencing commuters’ perceptions environment, with aim bridging gap interpreting environmental quality Thailand. Semantic segmentation was applied identify...

Abstract We investigated the feasibility of using multi-polarization Synthetic aperture radar (SAR) data to estimate thickness undeformed first-year ice. Analysis Signatures for C- and L-bands Showed that correlation between ice VV-to-HH backscattering ratio is larger than thicknesses coefficients. This in part because Surface Salinity hence reflection coefficient decreases as thickens. The had low Sensitivity Small-scale roughness C-band almost independent at L-band. Given most Sensitive...

In this paper, we propose a new method for improving detection of sea ice through use PALSAR (Phased-Array type L-band SAR) polarimetric data. Unlike traditional methods that are based on backscattering coefficient, our proposed utilizes scattering entropy to detect ice. We tested by comparing area derived from fully data covering the Sea Okhotsk acquired in 2009 and 2010 reference MODIS (Moderate Resolution Imaging Spectroradiometer) same region. applied discriminant analysis samples open...

As sustainable transport systems need to secure long-term benefits of users, it is useful compare the social land-use development between cities at different stages based on values local residents. In Asian developing megacities, Mass Rapid Transit (MRT) has recently been developed calm serious traffic congestion an early stage, facing rapid motorisation. On other hand, large in Japan have experienced MRT a late but they improvement system, ageing society. Both are required new quality...

Accessibility improvement for pedestrians has received increasing attention in planning. However, pedestrian space is more likely to be designed only individual streets secure minimum easiness of walking, and little been paid developing a street network walk around multiple destinations on neighbourhood scale. There also lack empirical analysis how much accessibility would vary depending the characteristics routes specific destinations. This paper aimed at examining spatial relationship...

We have developed three-dimensional magneto-optic spatial light modulators (3D-MOSLMs) that use magnetic domains as submicron scale pixels to represent holograms.
