Gathering Data

Modern medical devices involves information technology (IT) based on electronic structures for data and signals sensing and gathering, data and signals transmission as well as data and signals processing in order to assist and help the medical staff to diagnose, cure and to monitors the evolution of patients. By focusing on biological signals processing we may notice that numerical processing of information delivered by sensors has a significant importance for a fair and optimum design and manufacture of modern medical devices. We consider for this approach fuzzy set as a formalism of analysis of biological signals processing and we propose to be accomplished this goal by developing fuzzy operators for filtering the noise of biological signals measurement. We exemplify this approach on neurological measurements performed with an Electro-Encephalograph (EEG).

Method Of Paired Comparisons

Intransitivities in observers' preference judgments for multidimensional natural landscape scenes are examined. Thurstone's Law of Comparative Judgment (LCJ) psychophysical scaling routine is used to scale landscape preference. Both the method of Rank Ordering (RO) and the method of Paired Comparisons (PC) are used to gather the raw data necessary for scaling. The preference metric derived from the PC data which allows intransitivities to occur, is compared to the metric derived from the RO data, which does not allow observer intransitivity. Analysis indicates that an observer's expressed ordinal preferences derived from his PC data differs from that obtained from his RO data. Analysis also indicates that intransitivity exist to a moderate degree in each individual's expressed preferences and that this intransitivity is related to the differences between the two sets of ordinal preferences. However, very little difference exists between the two, LCJ derived, interval preference metrics obtained from group PC data and group RO data.

<span lang="EN-US">There is a growing consensus on the need to propose specific policies to face rural depopulation. This article applies fuzzy-set Qualitative Comparative Analysis (QCA) to define the presence or absence in each municipality of the conditions leading to the presence or absence of depopulation. We also perform Exploratory Spatial Data Analysis (ESDA) of population growth to identify hotspots of rural depopulation. The methodologies prove useful to evaluate and guide regional policies that address depopulation processes in the context of a relatively urbanized region.</span>
