Two mechanisms are proposed in this paper to be incorporated with IEEE 802.11e EDCA MAC protocol for providing the QoS provisioning capability of such network. First, the call admission control function, which considers the inherent contention access feature of 802.11 MAC, aims to satisfy the QoS requirement of established higher priority connections, while(More)
—Target and anomaly detection are important techniques for remotely sensed hyperspectral data interpretation. Due to the high dimensionality of hyperspectral data and the large computational complexity associated to processing algorithms, developing fast techniques for target and anomaly detection has received considerable attention in recent years.(More)
This study investigates several new aspects that are associated with Chinese ADRs' long term performance. We find that Chinese ADRs whose underlying firm is incorporated in an offshore center like the Cayman Islands or Virgin Islands perform poorly and whose firm planned to pay dividend at the time of ADRs' IPO perform better in a three year window. We also(More)
Target detection is an important topic for extracting information from hyperspectral imagery. Due to the high computational complexity, developing fast target detection algorithm has received considerable interest, specifically to take advantage of field-programmable gate array (FPGA) architecture in hardware implementation. In this paper, a novel streaming(More)
In this paper, a new method to fuse SAR and Multi-spectral images based on Contourlet- HIS transform to increase the interpretability of SAR image, because Contourlet transform could makes up the defects that two-dimensional wavelet transform can not capture the spatial details of the image effectively. TM multi-spectral images and ERS-2 SAR image are used(More)
