Object relational and object database (distributed) systems are used more and more in real applications due to their rich and extensible data types and query language mixing declarative assertions and navigations. Queries may frequently involve multiple collection traversais (i.e., path expression), possibly distributed. Moreover, predicates with quantifiers can also be included inside path exp...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

International Journal of Cooperative Information Systems

We claim that a dynamic agent infrastructure can provide a shift from static distributed computing to dynamic distributed computing, and we have developed an infrastructure to realize such a shift. We shall compare this infrastructure with other distributed computing infrastructures such as CORBA and DCOM, and demonstrate its value in highly dynamic system integration, service provisioning and ...

International Journal on Semantic Web & Information Systems

Dear readers: Semantics brings information closer to human thinking and decision making. WWW suddenly forces us to simultaneously deal with the complexity of modeling, reasoning and perceptions to support semantics, with the huge scale and heterogeneity of all imagin-able kind needed to deal with resources on the WWW. Semantic Web promises to allow for programs/agents to automatically understan...
