web usage mining (wum) is the automatic discovering of hidden informationof user access pattern from the web log data. frequent pattern discovery is one ofthe main techniques in wum that can be used to implement recommender systems,forecast user`s navigational behaviour, and personalize web sites. many algorithmshave been suggested on obtaining frequent user navigation patterns. this paperprese...

An improved range-Doppler algorithm (RDA) is proposed to reconstruct images from synthetic aperture radar (SAR) data received at high squint angles. At a higher squint angle, a larger synthetic aperture is required to receive sufficient amount of data for image reconstruction, and the range migration also becomes more serious, which demands more computational load and larger memory size. The pr...

In the near future we can expect to use global communication networks at negligible communication costs therefore, it is becoming increasingly profitable for commercial network service providers to achieve online availability. The services provided may be implemented as software application modules with operational interfaces that require calling clients to follow a service-specific protocol. S...

Edge caching (EC) decreases the average access delay of end-users through popular content at edge network, however, it increases leakage probability valuable information such as users preferences. Most existing privacy-preserving approaches focus on adding layers encryption, which confronts network with more challenges energy and computation limitations. We employ a chunk-based joint probabilis...
