in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

The aim of this paper is the determination of the largest n-dimensional polytope with n+3 vertices of unit diameter. This is a special case of a more general problem Graham proposes in [2].

Description Logic Programs (DLP) have been described as a description logic (DL) that is in the “expressive intersection” of DL and datalog. This is a very weak guideline for defining DLP in a way that can be claimed to be optimal or maximal in any sense. Moreover, other DL fragments such as EL and Horn-SHIQ have also been “expressed” using datalog. So is DLP just one out of many equal DLs in t...

In this paper, I analyse the synchronization of business cycles within the E.U., as this is an important ingredient for the implementation of a successful monetary policy. The business cycles of twelve E.U. countries and two sub-groups of countries are extracted for the period 1989Q1-2010Q2. The cycle of G3, the group of the three largest European economies (Germany, France and Italy) is then u...
