Turkey and the European Union: Modernizing a traditional state?
(Blackwell Publ LTD, 2003)This paper discusses the difficulties encountered when reforms are attempted to the administration of public policy in Turkey. This discussion is timely, since Turkey has recently stepped up its modernization agenda in its ... -
Generalized modeling principles of a nonlinear system with a dynamic fuzzy network
(Pergamon-Elsevier Science LTD, 2003)Generalized modeling principles of a nonlinear system with a dynamic fuzzy network (DFN)-a network with unconstrained connectivity and with dynamic fuzzy processing units called 'feurons', have been given. DFN model has ... -
1-N-substituted thiocarbamoyl-3-phenyl-5-thienyl-2-pyrazolines: Synthesis and evaluation as MAO inhibitors
(Wiley-V C H Verlag GMBH, 2003)Twelve new 1-N-substituted thiocarbomoyl-3-phehyl-5-thienyl-2-pyrazoline derivatives were synthesized and evaluated their for antidepressant, anxiogenic and mammalian monoamine oxidase (MAO)-A and B inhibitory activities ... -
Modeling of hysteresis and power losses in transformer laminations
(IEEE-Inst Electrical Electronics Engineers Inc, 2003)In this paper, a method for the representation of hysteresis and power losses in the laminations of power transformers is proposed. The developed model is based on data supplied from steel manufacturer and able to predict ... -
Extended partial path heuristic for real-time staging in oversubscribed networks
(Springer-Verlag Berlin, 2003)In this paper we propose the use of the PPH as a base for an offline schedule method to detect unsatisfiable requests in a staging system. This property allows a reduction in the overhead of transferring data-items with ... -
Controller design to enforce boundedness, liveness and reversibility in Petri nets
(Pergamon-Elsevier Science LTD, 2003)Supervisory controller design to enforce boundedness, reversibility, and liveness in ordinary Petri nets with weighted arcs is considered. Algorithms are presented to design a controller to enforce these properties ... -
Decentralized supervisory controller design to avoid deadlock in Petri nets (vol 76, pg 1285, 2003)
(Taylor & Francis LTD, 2003)… -
Extension of the Capon's spectral estimator to time-frequency analysis and to the analysis of polynomial-phase signals
(Elsevier Science BV, 2003)Incorporation of the linear time-varying filter and, its Zadeh's generalized transfer function concepts to the derivation of the Capon's minimum-variance spectral estimator leads to a new, bilinear, cross-term suppressed ... -
A theoretical approach to acidity-basicity behaviour of some biologically active 6-phenyl-4,5-dihydro-3(2H)-pyridazinone derivatives
(Elsevier Science BV, 2003)The acid dissociation constants, pK(a) values, of 12 biologically active 6-[p- or p- and m-substituted] phenyl-4,5-dihydro-3(2H)-pyridazinone derivatives were computed using semi-empirical methods. Correlations between the ... -
