Analysis of energy fluxes estimations over Italy using time-differencing models based on thermal remote sensing data

2012

Large area estimations of land surface fluxes can be a useful operational tool for up-scaling local measurements and can serve as an upper-boundary condition for higher spatial resolution applications. Given hourly measurements of radiometric surface temperature from a geostationary satellite, it is possible to derive the partitioning of energy fluxes based on the influence of the evapotranspiration process on morning surface temperature rise. In this work, the Atmosphere-Land Exchange Inverse (ALEXI) model and the Dual Temperature Difference (DTD) approach were applied in order to relate the sensible heat flux to time-differential remote observations of surface temperature obtained from Me…

Transpiration and Water Use of an Irrigated Traditional Olive Grove with Sap-Flow Observations and the FAO56 Dual Crop Coefficient Approach

2021

The SIMDualKc model was applied to evaluate the crop water use and the crop coefficient (Kc) of an irrigated olive grove (Olea europaea L.) located in Sicily, Italy, using experimental data collected from two crop seasons. The model applies the FAO56 dual Kc approach to compute the actual crop evapotranspiration (ETc act) and its components, i.e., the actual tree transpiration (Tc act), obtained through the basal crop coefficient (Kcb), and soil evaporation according to an evaporation coefficient (Ke). Model calibration was performed by minimizing the difference between the predicted Tc act and the observed daily tree transpiration measured with sap flow instrumentation (TSF field) acquired…

INTELLECTUAL FILTERS AND THE DISSEMINATION OF SMITHIANISM AN INTRODUCTORY NOTE

2020

Adfam Smith’s thought reached every corner of the world in a short lapse of time but made its entrance through institutional, cultural, linguistic, religious and political filters. These filters are not neutral and affected the reading, understanding and use of Smithian ideas. I chose the keyword ‘intellectual filters’ to denote all of the contextual elements whose influence determines whether and how a foreign paradigm penetrates a country and creates its effects.

FPGA Implementation of an Adaptive Filter Robust to Impulsive Noise: Two Approaches

2011

Adaptive filters are used in a wide range of applications such as echo cancellation, noise cancellation, system identification, and prediction. Its hardware implementation becomes essential in many cases where real-time execution is needed. However, impulsive noise affects the proper operation of the filter and the adaptation process. This noise is one of the most damaging types of signal distortion, not always considered when implementing algorithms, particularly in specific hardware platforms. Field-programmable gate arrays (FPGAs) are used widely for real-time applications where timing requirements are strict. Nowadays, two main design processes can be followed for embedded system design…

An Investigation of the Roles of Group Identification, Perceived Ability, and Evaluative Conditions in Stereotype Threat Experiences

2019

The Multi-Threat Framework distinguishes six qualitatively distinct stereotype threats. Up to now, few studies have been performed to identify the situational and individual determinants of different stereotype threat experiences. This study investigates the role of group identification, perceived ability, and evaluative conditions (private/public) in six stereotype threat experiences for 261 French Physical Education Students. The results show that the expression level of the different stereotype threats does not vary according to evaluative conditions. In contrast, group identification affects all the forms of stereotype threats, and for three forms of stereotype threats, this effect is …

Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting

2019

The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was …

Childhood abuse experiences, depression and dissociation symptoms in relation to suicide attempts and suicidal ideation

2021

This study aimed to examine associations between suicide attempts (SA), suicidal ideation (SI), depression, dissociative symptoms, emotional abuse, physical abuse and sexual abuse, and to explore predictors of SA and SI, as well as possible mediating factors. We also aimed to examine support for a dissociative depression subgroup. Participating in this study were 342 adults, of these were 138 respondents with a diagnosis of depression (DG), and 204 respondents comprising a community sample (CS). Respondents completed the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R), Childhood Trauma Questionnaire - Short Form (CTQ-SF), and Dissociative Experience Scale (DES). All but…

Modern health worries and idiopathic environmental intolerance attributed to electromagnetic fields are associated with paranoid ideation.

2021

Paranoid ideation is assumed to characterize worries about possible harmful effects of modern technologies (MHWs) and idiopathic environmental intolerances (IEIs), such as IEI attributed to electromagnetic fields (IEI-EMF). Empirical evidence on these associations is scarce.In a cross-sectional on-line survey, participants of a community sample (n = 700; mean age: 28.4 ± 12.0; 434 females) completed the Somatosensory Amplification Scale, the Modern Health Worries Scale, and the Paranoid Ideation scale of the Symptom Checklist 90 Revised. They were considered IEI-EMF if (1) they categorized themselves so, (2) they had experienced symptoms that they attributed to the exposure to electromagnet…

Carotid intima-media thickness measurement through semi-automated detection software and analysis of vascular walls

2013

AIM: The aim of the present study was to compare the semi-automatic measurement of carotid intima thickness (RFQIMT - Esaote, Italy), with the conventional method. METHODS: We enrolle 81 patients, mean age 46 years ±15, with no history of cardio-cerebrovascular events and we assessed the traditional cardiovascular risk factors. We examined the IMT of the common carotid artery with manual and RFQIMT method (based on the "Radio Frequency" signal), according to the ASE protocol. RESULTS: Semi-automatic measurement was on average lower than manual measurement (617 μm ±191 vs. 676 μm ± 222) with a statistically significant difference (P<0.01). In agreement with manual measurements, the values of…
