In this paper, we describe an approach to database preference queries based on the notion of outranking, suited to the situation where preferences on different attributes are not commensurable.This model constitutes an alternative to the use of Pareto order Side Tables whose main drawback is to leave many tuples incomparable in general.Even though
The halogen-bond (X-bond) Pillows donors 1,3- and 1,4-diiodotetrafluorobenzene (1,3-di-I-tFb and 1,4-di-I-tFb, respectively) form cocrystals with trans-1,2-bis(2-pyridyl)ethylene (2,2′-bpe) assembled by N···I X-bonds.In each cocrystal, 2(1,3-di-I-tFb)·2(2,2′-bpe) and (1,4-di-I-tFb)·(2,2′-bpe), the donor mo
The instantaneous phase signal contains abundant information about the health state of machineries, which plays an important role in fault detection of machineries, rotor dynamic Support balance, transmission error of Rotate Vector reducer, etc.Traditional methods use signal processing methods based on encoders, EMD and Hilbert transforms or fracti
The study was conducted in Tehulederie, Kalu, and Dessie Zuria districts of South Wollo 7 Piece King Panel Bedroom Package Zone, Amhara, Ethiopia, to assess the current beekeeping production system with available opportunities and challenges facing the beekeeping subsector.The districts were purposively selected based on potential and accessibility
