In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC Ice Bucket code pair) in a joint source-channel coding (JSCC) system.Specifically, we pre-set the girth
Oceanic environments are one of the largest sources of bioactive molecules, due to the high degree of biodiversity and the innumerable ecological relationships established between macro and microorganisms found in the different ecosystems of these complex environments.Marine organisms are being studied increasingly because they are considered impor
In the past, several Asian subspecies and local forms of Zootecus have been described and some of them can be linked back to Zootecus insularis.Their collecting sites, shell shapes, dimensions and number of whorls have been listed in the past.In recent years, collections, observations and biometrics of dead shells have been carried out in five site
Malware attack is growing day by day in cyberspace.And Wireless Sensor Masks Network (WSN) is also facing a hazardous type of situation due to attack of malware (malicious code, virus, worm etc.).Malwares target sensor nodes easily because, nodes are equipped with limited resources.Hence, security of WSN against malware attack is one of the imperat
