Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...

the study of the dynamic behavior of a rigid body with one fixed point (gyroscope) has a long history. a number of famous mathematicians and mechanical engineers have devoted enormous time and effort to clarify the role of dynamic effects on its movement (behavior) – stable, periodic, quasi-periodic or chaotic. the main objectives of this review are: 1) to outline the characteristic features of...

Despite showing an overtly simple structure, the semantic process in classic literary-narrative discourse conforms to complicated semiotic systems. As a result, semio-semantics is deemed as one of the most scientific, reliable tools since it helps intradiscursive semio-textual propositions be phenomenologically, and even epistemologically, analyzed. Consequently, the narrative discourse in “The...
