This exploratory study attempts to prove the premise that performance measurements are instrumental in the often inconsistent and dynamic supplier selection problem. The fundamental Supply Chain Management (SCM) phases of Plan, Source, Make, and Deliver and at what level of managerial decision making (Operational, Tactical or Strategic) are the performance measures considered in supplier selection...
Previous experimental studies on rabbits using electrocorticograms (ECoGs) over the cortical surface indicate spatio-temporal dynamics in the form of amplitude modulation (AM) patterns, which intermittently collapse at theta rates and give rise to rapidly propagating phase modulated (PM) patterns. The observed dynamics have been shown to be of cognitive relevance carrying useful information on the...
Transient cortical oscillations in the form of rapid synchronization-desynchronization transitions are key candidates of neural correlates of higher cognitive activity monitored by scalp EEG and intracranial ECoG arrays. The transition period is in the order of 20–30 ms, and standard signal processing methodologies such as Fourier analysis are inadequate for proper characterization of the phenomenon...
Experimental and theoretical approaches aiming at the establishment of neural correlates of higher cognitive functions and awareness have been extensively studied in the past decade. Information-theoretical indices are useful tools in establishing quantitative metrics when analyzing data of cognitive experiments. In this work we report a systematic statistical analysis of multiple runs of ECoG measurements...
Neural correlates of higher cognition and awareness are studied based on rabbit electrocorticogram (ECoG) experiments due to W.J. Freeman. Experimental evidence is presented on the onset of synchronization of neural activity across large cortical areas during high -evel cognitive functions and awareness experience. The observed synchronization effect has significant invariance over a broad-range of...
We apply Hilbert transforms to the analysis of phase relationship in elecrocoticogram (ECoG) signals in order to explore a set of meaningful information theoretic measures. This analysis leads to a methodology to derive meaning from experimentally observed brain dynamics under various states induced by sensory stimuli. We explore the possibility to represent periods of habituation and learning based...
