In this paper, the diagnosability of n-dimensional star graph S n under the comparison diagnosis model has been studied. It is proved that S n is (n − 1)-diagnosable under the comparison diagnosis model when n 4.
The wavelength routed optical network (WRON)  is a promising optical interconnection architecture that can be integrated into a System-on-Chip (SoC) to replace traditional wire-connected on-chip micro-networks which pose severe bandwidth limitations on future super large SoC chips. In this paper, we present the architecture of WRON and generalize the… (More)
Horizon line detection is a demanding problem in various tasks associated with planet exploration, because no standard approaches such as global positioning system is available. Horizon line is a boundary line defined between a sky and non-sky region in 2D images, and it is an important visual clue that can be utilized for calculating the rover's… (More)
Planetary rover localization is a challenging problem since no conventional methods such as GPS, structural landmarks etc. are available. Horizon line is a promising visual cue which can be exploited for estimating the rover's position and orientation during planetary missions. By matching the horizon line detected in 2D images captured by the rover with… (More)
Sky segmentation is an important task for many applications related to obstacle detection and path planning for autonomous air and ground vehicles. In this paper, we present a method for the automated sky segmentation by fusing K-means clustering and Neural Network (NN) classifications. The performance of the method has been tested on images taken by two… (More)
In current Personal Communication Service (PCS) Networks, such as Global Systems for Mobile Communications (GSM), the always-update (AU) strategy is used to keep track of mobile terminals (MTs) within the network. However, future PCS networks, like Universal Mobile Telecommunication System (UMTS) envision larger number of MTs and smaller cells. This will… (More)
Effective location management is critical for future personal communication service (PCS) networks, which envision smaller cells comprising a vast number of mobile terminals. In this paper we present a dynamic location management scheme with personalized location areas. The proposed technology takes into account the mobility patterns of the individual users… (More)
