scalability by replicating identical packets at routers. However, since its initial proposal the IP-multicast has not been widely enabled due to the slow pace of its deployment. Hence, the application-level multicast concept emerged to solve this deployment issue by shifting the multicast support from routers to end-systems. The article reviews the most important facts of the Application-Level ...

Assigning a set of objects to groups such that objects in one group or cluster are more similar to each other than the other clusters’ objects is the main task of clustering analysis. SSPCO optimization algorithm is anew optimization algorithm that is inspired by the behavior of a type of bird called see-see partridge. One of the things that smart algorithms are applied to solve is the problem ...

predicates are words or groups of words which are considered as the most important semantic elements of the sentence. following manouilidou, almeida, schwartz and nair, this research investigates the nature of verb disorder in persian alzheimer patients. to this end, the property of thematic role assignment by three kinds of predicates has been focused upon. the first kind of predicates include...

Thematic map symbol is a basic component of thematic map language and it plays an important role in expressing the thematic content. However, the extensity of users leads to the diversity and complexity of the thematic symbols and expression methods, and most of the thematic maps do not have a fixed format and norms like topographic map. At the same time, we can not require all the users to be ...
