Distributed constraint optimization problems (DCOP) have attracted attention as a means of resolving distribution problems in multiagent environments. We [1] proposed a multiplex method target ing the improved effic iency of a d ist r ibu ted nondeterministic approximation algorithm for distributed constraint optimization problems. The multiplex method target ing the improved effic iency of a d...

Abstract The study investigates the performances of high efficiency flat solar thermal collectors, under climatic conditions Galați, Romania. same mathematical model was used to evaluate stationary and transitory behavior 12 effic iency with reduced heat losses. characteristics collectors were extracted from technical reports two European independent testing laboratories. annual specific energy...

The liberalisation movement in European airlines industry was initiated in the late 1980s to create a more competitive environment. This has aimed to result in an increase in efficiency and productivity of the industry. The radical changes which have occurred since then have given risen to the need to evaluate the efficiency in the early phases of the liberalisation process. This study utilises...

The Tyndall Mote is a technology platform for research activities in Wireless Sensor Networks (WSN). BEM is one of the major application areas as it has been demonstrated that energy effic iency savings of up to 1520% are possible by using WSN technology in smart build ing applications [1]. The current mote design offers a modular, flexible and stackable solution. But for next generation design...

This study investigates the usage of adaptive directed antennas for the Mobile Broadband System (MBS). Advantages and problems are considered. Solutions f o r the problems are proposed and evaluated with respect t o cost, feasibility and ef ic iency.

Among the conventional time-scale modification methods [1][6], the synchronized overlap and add (SOLA) method [4] is used widely because of its good performance with relatively low computational complexity. But the SOLA method still requires much computation in evaluating the normalized crosscorrelation function for synchronization procedure [9]. In this paper, we employ 3 level center clipping...
