Three dimension data are in great demand for the various applications such as 3D GIS, navigation, digital archive, simulation, computer games, and so on. In order to represent space in details, it is indispensable to acquire 3D shape and texture together. However, there still lacks a reliable, quick, and handy method of acquiring three dimension data at(More)
—To represent 3-D space in detail, it is necessary to acquire 3-D shapes and textures simultaneously and efficiently through the use of precise trajectories of sensors. However, there is no reliable, quick, cheap, and handy method for acquiring accurate high-resolution 3-D data on objects in outdoor and moving environments. In this paper, we propose a(More)
The retrieval of nutrient concentration in sugarcane through hyperspectral remote sensing is widely known to be affected by canopy architecture. The goal of this research was to develop an estimation model that could explain the nitrogen variations in sugarcane with combined cultivars. Reflectance spectra were measured over the sugarcane canopy using a(More)
Tree parameter determinations using airborne Light Detection and Ranging (LiDAR) have been conducted in many forest types, including coniferous, boreal, and deciduous. However, there are only a few scientific articles discussing the application of LiDAR to mangrove biophysical parameter extraction at an individual tree level. The main objective of this(More)
Savannakhet Province, Lao People's Democratic Republic (PDR), is a small area that is connected to Thailand, other areas of Lao PDR, and Vietnam via road No. 9. This province has been increasingly affected by carbon dioxide (CO 2) emitted from the transport corridors that have been developed across the region. To determine the effect of the CO 2 increases(More)
ÑA new fault simulator (VFSIM) for synchronous sequential circuits has been developed and applied to random access scan circuits of several hundred LSIs in mainframe computers. The results show that VFSIM is one or two orders of magnitude faster than a conventional fault simulator designed for random access scan circuits. A vectorized pattern parallel(More)
Three dimensional data is in great demand for disaster and environmental monitoring. In order to represent 3D space in details, it is indispensable to acquire 3D shape and texture together efficiently. However, they still lack a reliable, quick, cheap and handy method of acquiring three dimensional data of objects at higher resolution and accuracy in(More)
The submerged tree volume and the projection area of mangroves play a significant role in damping tsunami inundation flow with a distinct root formation above ground. We modeled the stilt root morphology of the Rhizophora sp., especially to incorporate into a hydraulic drag of tsunami inundation simulation. The equivalent Manning’s roughness coefficient has(More)
In the case of natural hazards the spatial extent of the disaster area is usually large. It is often difficult to conduct search and rescue operations from the ground. Such operations are often hindered due to the inaccessibility to the locality due to the damaged infrastructures. But it is often crucial that the victims are identified and rescued as soon(More)
