background: the success of faculty members of medical sciences universities in medical education arena requires qualification and capabilities authentication in relation with education.  in order to achieve these capabilities, it is necessary to use new and influential approaches of empowerment. one of the appropriate approaches is “competency based training” (cbt). in this method, competencies...

Strut-and-Tie Models (STM) for the design of concrete beams, comprising of struts, ties, nodes as the basic tools, is conceptually simple, but its realization for complex concrete structure is not straightforward and depends on flow of internal forces in the structure. STM technique has won wide acceptance for deep member and shear design. STM technique is a unified approach that considers all ...

An approach of membership revocation in group signatures is verifier-local revocation (VLR for short). In this approach, only verifiers are involved in the revocation mechanism, while signers have no involvement. Thus, since signers have no load, this approach is suitable for mobile environments. Although Boneh and Shacham recently proposed a VLR group signature scheme from bilinear maps, this ...

Michele Zorzi, Member, IEEE, and Ramesh R. Rao, Senior Member, IEEE Abstract— In this paper, an ARQ Go-Back-N protocol with unreliable feedback and time-out mechanism is studied, using renewal theory. Transmissions on both the forward and the reverse channels are assumed to experience Markovian errors. The exact throughput of the protocol is evaluated, and simulation results, that confirm the a...

In this paper, we propose a rate control mechanism for multimedia multicast streaming in the Internet. A single and optimal transmission rate that is adaptive to the network congestion, buffer occupancies, and the playback requirements of the member clients in the multicast group is allocated. We optimize the multicasting delivery in the Internet by improving the buffer occupancy of all clients...

Lensing of one member of a binary by its companion is studied for several classes of binaries. For binaries in which at least one member is an ordinary (non-compact) star, the optical depths to lensing is extremely low, < v 4 esc =c 4 10 11. Here v esc is the escape velocity from the component with the weaker potential. Binaries composed of two compact objects can have higher optical depths. Ab...

This paper analyzes the evolution of regional unemployment rates, wages, participation rates, migration and employment in seven candidate countries for accession to the European Union (EU) in the 1990s. We compare these countries to a core set of EU member states and find persistent regional disparities in both regions. However, persistence of unemployment rates is lower in the first-round cand...

The 2008-09 crisis has shown that some euro area member countries were unable to sufficiently stabilize their economies which has given rise to a debate about deeper fiscal integration in Europe. In this paper, we analyze the redistributive and stabilizing effects of two scenarios of fiscal integration in the Eurozone, namely the introduction of i) a joint tax and transfer system that replaces ...
