In this paper, we introduce memos, which integrates suitable memory management policies and schedules resources over the entire memory hierarchy in hybrid memory system. Powered by an OS kernel level monitoring tool, memos captures memory patterns online, and then leverages them to guide the memory page placement and data mapping. Experimental results show, on average, memos can benefit memory utilization,...
Plant biomass is an important parameter for crop management and yield estimation. The potential of compact polarimetric (CP) synthetic aperture radar (SAR) data in estimating biomass of oilseed rape crop (Brassica napus L.) is investigated in this study. Five CP SAR imagery was simulated using five fully polarimetric Radarsat-2 data, and the dynamic evolution of polarimetric features, relying on different...
The study aimed to develop a universal method to monitor soil APC by hyperspectral data. The correlations between soil APC and the hyperspectrum reflectivity and its mathematical transformations were analyzed. The feature bands and its transformations were screened to develop the optimizing model of monitoring soil APC based on the method of multiple linear regression. The in-situ testing samples...
The feasibility of monitoring lodging of wheat fields by exploiting fully polarimetric C-band radar images has been investigated in this paper. A set of backscattering intensity features and polarimetric features, derived by target decomposition techniques, was extracted from 5 consecutive Radarsat-2 images. The temporal evolutions of these features of lodging wheat fields were investigated as a function...
The potential capability of C-Band fully polarimetric synthetic aperture radar data for monitoring canola height was investigated in this study. Polarimetric parameters of canola fields were extracted with polarimetric decompositions method from multi-temporal Radarsat-2 images. Temporal behavior of polarimetric features with different varieties and sowing dates was presented from its sowing to its...
A number of shocking cyber-attacks have happened in recent years, and the damage they have caused has led to the emergence of cyber-security as a consideration when designing embedded systems. Software vulnerability and physical attack are the most severe threats the system face. This paper provides information about hardware designed to monitor potential intrusions and incidences of unauthorized...
Mobile video surveillance system based on ARM9 uses unique high-bandwidth business applications of 3G wireless network. The design of hardware and software of embedded monitoring system is described. The running platform of 3G network show that the system can work well in the circumstances of the limited bandwidth.
