The Global Workspace Theory and Information Integration Theory are two of the most currently accepted consciousness models; however, these models do not address many aspects of conscious experience. We compare these models to our previously proposed consciousness model in which the thalamus fills-in processed sensory information from corticothalamic feedback loops within a proposed 3D default s...

With the recent increasing build and application for 3D spatial information, the importance of management and application for spatial information based on indoor space has been increased. Especially, Due to the increasing of the scale and complexity of the building according to the development of construction technologies several studies have been conducted to provide the services based on indo...

Since September 11, 2001, geospatial researchers have been interested in utilizing GIScience technologies to solve geographical questions in micro-scale space in built-environments such as indoor space within a building. The indoor space should be dealt with differently from outdoor space in order to provide integrated and seamless location-based services (Li, 2009). The indoor LBS applications...

We are developing a system to acquire 3D sound-space information that can transmit accurate sound-space information to a distant place using a microphone array on a human-head-sized solid sphere with numerous microphones on its surface. The system comprises an object with numerous microphones called Symmetrical object with ENchased ZIllion microphones (SENZI). Each recorded signal from spatiall...

Currently, demands on 3D GIS increase, so spatial data analysis in 3D space also is required. Especially as large-scale and complex indoor space has been developed, it is more important to analyze human behaviors in complicated 3D indoor space to find accident spots or calculate evacuate routes. In order to do that, it is essential to represent topological relationships among the 3D entities in...

The purpose of this study was to investigate how fast three-dimensional (3D) MR image quality is affected by breath-holding and to develop an optimal breath-holding strategy that minimizes artifact in the event of an incomplete breath-hold. A computer model was developed to study variable-duration breath-holds during fast 3D imaging. Modeling was validated by 3D gradient-echo imaging performed ...
