Optimal Placement of Pressure Sensors Using Fuzzy DEMATEL-Based Sensor Influence
2020
[EN] Nowadays, optimal sensor placement (OSP) for leakage detection in water distribution networks is a lively field of research, and a challenge for water utilities in terms of network control, management, and maintenance. How many sensors to install and where to install them are crucial decisions to make for those utilities to reach a trade-off between efficiency and economy. In this paper, we address the where-to-install-them part of the OSP through the following elements: nodes' sensitivity to leakage, uncertainty of information, and redundancy through conditional entropy maximisation. We evaluate relationships among candidate sensors in a network to get a picture of the mutual influenc…
Stochastic Multicriteria Acceptability Analysis (SMAA)
2010
Stochastic multicriteria acceptability analysis (SMAA) is a family of methods for aiding multicriteria group decision making in problems with uncertain, imprecise or partially missing information. These methods are based on exploring the weight space in order to describe the preferences that make each alternative the most preferred one, or that would give a certain rank for a specific alternative. The main results of the analysis are rank acceptability indices, central weight vectors and confidence factors for different alternatives. The rank acceptability indices describe the variety of different preferences resulting in a certain rank for an alternative, the central weight vectors represe…
The Mediating Role of Orthorexia in the Relationship between Physical Activity and Fear of COVID-19 among University Students in Poland
2021
Previous research showed that the COVID-19 pandemic has a significant impact on the wellbeing and lifestyle of populations worldwide, including eating and physical activity (PA) patterns. The present study aims to examine the mediating effect of orthorexia on the relationship between PA and fear of COVID-19. A sample of 473 university students from Poland of a mean age of 22 years (M = 22.04, SD = 2.90, 47% of women) participated in the cross-sectional online survey study. Continuous variables were measured using the Fear of COVID-19 Scale (FCV-19S) and the Test of Orthorexia Nervosa (TON-17), while categorical variables divided participants into the physically active and inactive group reg…
Invisalign treatment from the patient perspective: A Twitter content analyses
2021
Background: Understanding patient perspective is a key factor in improving treatment satisfaction. The aim of the present study is to qualitatively describe the content of Twitter posts related to the treatment with Invisalign in order to get a better understanding of patient experience. Material and Methods: Tweets were prospectively collected during a period of four weeks from public available posts on Twitter using Awario™ a bespoke social media monitoring tool. After applying the pertinent inclusion and exclusion criteria the selected posts were analysed by three investigators using thematic analysis. Specific themes and subthemes were developed. Results: A total of 1564 tweets were ana…
Células del cuello uterino con atipias que no descartan una lesión de alto grado (ASC-H) con premalignidad
2019
Introducción: la presencia de células escamosas con atipias que no descartan una lesión intraepitelial escamosa de alto grado (ASC-H) es significativa, pues cerca de 50% podrían corresponder a una lesión premaligna del cérvix uterino. Objetivo: describir las alteraciones citomorfológicas más frecuentes en los extendidos citológicos categorizados como células escamosas con atipias que no descartan una lesión intraepitelial escamosa de alto grado (ASC-H), con existencia de lesión clínicamente significativa en el resultado histopatológico. Metodología: estudio retrospectivo en el laboratorio de citología de la Facultad de Farmacia y Bioanálisis, Universidad de Los Andes y Clínica de Prevención…
Boundary Issues in New Metropolitan Cities
2012
In the last decade, the focus of Italian politics aimed at the definition of metropolitan cities and independent associations of municipalities has become increasingly important. With regard to legislation, the issue has been considered since the 1990s, but despite several debates and legislative reforms there have been no real results. The only approach used was political-institutional, anchored in obsolete patterns and unable to deal with existing realities.Urban Planning and Urban Studies materialize the political choices in operational programs and control the evolution of urban and territorial transformations. These disciplines represent the starting point to reflect upon the process o…
Impact of systematic whole-body 18F-fluorodeoxyglucose PET/CT on the management of patients suspected of infective endocarditis: the prospective mult…
2021
AbstractBackgroundDiagnostic and patients’ management modifications induced by whole-body 18F-FDG-PET/CT had not been evaluated so far in prosthetic valve (PV) or native valve (NV) infective endocarditis (IE)-suspected patients.MethodsIn sum, 140 consecutive patients in 8 tertiary care hospitals underwent 18F-FDG-PET/CT. ESC-2015-modified Duke criteria and patients’ management plan were established jointly by 2 experts before 18F-FDG-PET/CT. The same experts reestablished Duke classification and patients’ management plan immediately after qualitative interpretation of 18F-FDG-PET/CT. A 6-month final Duke classification was established.ResultsAmong the 70 PV and 70 NV patients, 34 and 46 wer…
A Methodology for Solving the Multiple Criteria Macroeconomic Policy Problem
1983
In this paper we review the results of our research on using interactive multiple criteria optimization methods for solving macroeconomic policy problems in Finland. An existing econometric model describing the interrelationships between different variables and sectors of the economy is used. In addition, the current status of the implementation work is reported and some possibilities for future research are discussed.
Substitution of carcinogenic solvent dichloromethane for the extraction of volatile compounds in a fat-free model food system
2016
International audience; Dichloromethane is known as a very efficient solvent, but, as other halogenated solvents, is recognized as a hazardous product (CMR substance). The objective of the present work is to propose substitution solvent for the extraction of volatile compounds. The most important physico-chemical parameters in the choice of an appropriate extraction solvent of volatile compounds are reviewed. Various solvents are selected on this basis and on their hazard characteristics. The selected solvents, safer than dichloromethane, are compared using the extraction efficiency of volatile compounds from a model food product able to interact with volatile compounds. Volatile compounds …
Retrospective evaluation of the clinical performance of direct composite restorations using the snow-plow technique : up to 4 years follow-up
2019
Background To evaluate the clinical performance of direct composite restorations using the snowplow technique with up to 4 years of follow-up. Material and methods In this retrospective study, 101 class II composite restorations which were placed in permanent molars (n = 19) and premolars (n = 82) in 85 patients by the snowplow technique, were evaluated according to the modified USPHS criteria. A Kaplan-Meier analysis with a 95% confidence level was used to calculate the survival probability. Results Of the 101 teeth examined, tooth failure was identified in 8 teeth due to secondary caries (3%), marginal gap (2%), marginal discoloration (1%) and restoration breakdown (2%) which required rep…
