AGENT’S NEGOTIATION USING PAXOS
This paper describes an approach of agent negotiation using Paxos.
The Paxos algorithm is an elegant solution for the consensus problem and also,
a mechanism for the delivery of totally ordered messages that can be used to
support active replication. Consensus is an algorithm for agreement in the
presence of failures. However, the purpose is to ensure that a value that was
proposed is eventually chosen and, some process can eventually learn the
chosen value. Furthermore, the agent may use Paxos protocol in order to
negotiate on the same value.

20-18 MODELAREA PILELOR CU COMBUSTIBIL CU MEMBRANĂ SCHIMBĂTOARE DE PROTONI

PROTON EXCHANGE MEMBRANE FUEL
CELL SYSTEM DEVELOPMENT
Proton exchange membrane fuel cell (PEMFC), with low polluting
emissions, is a great alternative to replace the traditional power sources. The
fuel cell generates electric power and heat power, which can be used to feed
electrical and heat customers. This paper presents a study of the PEMFC
system.

EFFICIENCY OF PROTON EXCHANGE
MEMBRANE FUEL CELL
Fuel cells power generating systems represent a solution to replace
traditional power sources because of their high efficiency and multiple
applications. Fuel cell technology is based on the concept of direct
electrochemical energy conversion. Proton exchange membrane (PEM) fuel
cells show great promise for use as distributed generation sources.
