In particular, some run-time packers only decrypt individual regions of code on demand, re-encrypting them again when they are not running. This technique is known as shifting decode frames and it can greatly complicate malware analysis. The first solution t...

The extent of piracy for a specific digital good can be characterized by the laws of demand and supply. The music industry and its trade organization, the RIAA, have recognized this and taken aggressive steps to diminish demand as well as supply.

Since fewer nodes store files for which there is a lower demand, these files are more likely to be lost from the P2P networks if users leave the network or delete the files. File loss can cause users to seek alternatives to P2P services, and lead to de...

This research deals with some specific water quality parameters of the Buriganga River, which include: temperature, pH, di...
