To explore the effects of white matter in the absence of auditory input in the early deaf, we conducted a tract-based statistical analysis of the diffusion tensor anisotropy and the voxel-based morphometry in the white matter of 13 early deaf and 29 hearing individuals. Deaf individuals showed significant decreases in diffusion anisotropy and in regional(More)
This study examined the characteristics of the knowledge discovery and data mining algorithms to demonstrate how they can be used to predict health outcomes and provide policy information for hypertension management using the Korea Medical Insurance Corporation database. Specifically, this study validated the predictive power of data mining algorithms by(More)
Capsule Endoscopy(CE) is a new modality for convenient and accurate investigation of small bowel pathology including obscure gastrointestinal bleeding. In this paper, we present a method for automatic detection of the bleeding region for a new high performance CE system with a new feature index in CE. The CE transmits 3 images per second to the receiver for(More)
In this paper, we propose a novel indoor localization technique of Unmanned Aerial Vehicle (UAV) using passive UHF far-field RFID systems. First, this paper presents impact of existence of UAV to RFID system. According to our empirical results, the existence of UAV, in a monitoring area, induces RF shadowing and Received Signal Strength Indicator (RSSI)(More)
Initial ranging process plays an important role in the mobile worldwide interoperability for microwave access (WiMAX) standard (IEEE 802.16e). Timing offset adjustment, power offset calculation and synchronization between the base station and all the users within a cell are achieved during the initial ranging process. A comparative study of existing and a(More)
Location sensing of physical objects is one of critical issues in many applications. Passive UHF Radio Frequency Identification (RFID) technique provides an efficient solution because of its low cost for installation and easy identification of the tagged physical objects. In this paper, we research on the localization problem using passive UHF RFID systems.(More)
Water bodies are essential to humans and other forms of life. Identification of water bodies can be useful in various ways, including estimation of water availability, demarcation of flooded regions, change detection, and so on. In past decades, Landsat satellite sensors have been used for land use classification and water body identification. Due to the(More)
For applications of embedded systems, several processors are scheduled on a processor because very limited applications are used. Recently application areas are broadened and used to be like personal computers. Operating systems are considered one of critical factors to develop embedded systems. Linux is becoming one of popular operating systems for(More)
In this research, we studied influence of the operating frequency of RFID system to the performance of stationary passive UHF far-field RFID based localization systems with KNN and LDTI algorithms. According to the empirical results, the localization system can be significantly varied by frequencies with the reference identification rate.
