Relying has in use for decades to tackle some of the challenges of wireless communication such as extending transmitting distance, transmitting over rough terrains. Relaying also achieve diversity which was proposed recently as an effective means to combat channel fading. In this work, effect of time and power allocation on relay performance is stu

Not all farmlands are purchased for farming. Where development pressures are strong and urban boundaries still fluid, some farmlands are purchased for non-agricultural purposes. However, since the future development use is not evident or pre-determined at the time of transaction, the farmland market may appear to operate as one albeit with latent s

The performance has a central importance for all cryptosystems. This paper aims to provide a framework and platform to evaluate a performance of Modified Dӧmӧsi’s Cryptosystem, a stream cipher based on finite automata, comparing to Data Encryption Standard. The performance is evaluated in terms of encrypting time and throughput.International Jo

Recitation of the Holy Quran with the correct Tajweed is essential for every Muslim. Islam has encouraged Quranic education since early age as the recitation of the Quran correctly will represent the correct meaning of the words of Allah. It is important to recite the Quranic verses according to its characteristics (sifaat) and from its point of ar

This paper proposes a new symmetric cryptosystem based on nondeterministic finite automata. It is shown that nondeterminism allows to reduce the dependency of key automata on a large descriptional complexity and irreversibility of the automata. Moreover, it is proven that the introduced cryptosystem has higher security and more efficient performanc
