Effects of Demand Side Management on the Operation of an Isolated LV Microgrids
2019
The work presents the results of a study regarding the impact of Demand Side Management actions on flexible loads distributed at the domestic end-users' facilities in an isolated low voltage microgrid. Aim of the research study is to evaluate how the implementation of local control actions on the end-user's side can impact on the operation of the isolated microgrid. The Demand Side Management is applied by each domestic user to optimize the operation of its own resources following well-defined operative steps. The study is carried out implementing a suitable model of the microgrid in Neplan environment, while the daily controlled load profiles of the end-users are evaluated using the Montec…
Shaping ability of nickel-titanium rotary instruments in simulated S-shaped root canals.
2009
Objective The aim of this study was to compare the shaping ability of 4 nickel-titanium rotary techniques and 1 hand technique in simulated S-shaped curved root canals. Study design Seventy-five simulated double-curved resin root canals were divided into 5 groups (n = 15). The canals were compared at 12 different levels and at 3 different times: before preparation and after preparation to master apical 25 and 35. Data were statistically analyzed by performing 2-by-2 comparisons with the Tukey parametric test of variance analysis using a confidence interval of 95%. Results All of the 75 resin blocks presented transportation of the root canals by transforming the apical curvature into a strai…
Assessing therapist development: Reliability and validity of the Supervisee Levels Questionnaire (SLQ-R).
2019
BACKGROUND Therapist development is a crucial target for clinical training in order to ensure high-quality psychotherapy. A major challenge in examining therapeutic development is the assessment of developmental processes. The Supervisee Levels Questionnaire (SLQ-R) was analyzed in this study to examine its validity, reliability, and underlying dimensional structure. METHOD Seven hundred and sixty therapists participated in an online survey concerning their current psychotherapy training. The factor structure as well as the validity of the SLQ-R were investigated using exploratory and confirmatory factor analysis. RESULTS In line with the results of the exploratory factor analyses, a Bifact…
Propiedades psicométricas y estructura de los factores de la escala de Satisfacción con la Vida en una muestra de estudiantes mayores portugueses jub…
2018
Abstract The main purpose of this study is to analyse the psychometric properties of the Satisfaction with Life Scale (SWLS) in a 363 retirees students sample from several Portuguese universities. The 70% were female (253) and 30% were male (110) with an average age of 67 years (SD = 7.59) and a range from 48 to 90 years. R Commander was used for Exploratory Factor Analysis (EFA) and Amos 18.0 module for Confirmatory Factor Analysis (CFA). One factor solution was the best-fitting model. The internal consistency of the SWLS was .777. Correlational analysis showed negative relationships with loneliness (UCLA Scale) and symptoms of depression (GDS-15), supporting concurrent validity. The SWLS …
Random Slicing: Efficient and Scalable Data Placement for Large-Scale Storage Systems
2014
The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach usable, it is necessary to provide a solution to locate data items in such a dynamic environment. This article presents and evaluates the Random Slicing strategy, which incorporates lessons learned from table-based, rule-based, and pseudo-randomized hashing strategies and is able to provide a simple and efficient strategy that scales up to handle exascale data. Random Slicing keeps a small table with information about previous storage system insert and remove operations…
The comparison of reliabilities in dental imaging methods.
2003
Objectives: Common practice in the statistical comparison of imaging instruments with limited reproducibility consists in the separate estimation of the instrument's reliabilities. However, as soon as one of the imaging methods is subject to item-specific bias (which has to be expected in many dentomaxillofacial imaging procedures), this approach will end in severe errors in reliability computation and in corresponding erroneous clinical conclusions. This paper seeks to point out these effects and to illustrate a more appropriate model for the comparison of instrumental reliabilities. Methods: A standard reliability model was adjusted for item-specific bias and illustrated by the comparison…
On the Reliability of Error Indication Methods for Problems with Uncertain Data
2012
This paper is concerned with studying the effects of uncertain data in the context of error indicators, which are often used in mesh adaptive numerical methods. We consider the diffusion equation and assume that the coefficients of the diffusion matrix are known not exactly, but within some margins (intervals). Our goal is to study the relationship between the magnitude of uncertainty and reliability of different error indication methods. Our results show that even small values of uncertainty may seriously affect the performance of all error indicators.

Responsabilità degli organi di amministrazione e controllo di società a partecipazione pubblica (anche in house) e riparto di giurisdizione
2019
Le disposizioni in tema di responsabilità degli organi di amministrazione e controllo di società a partecipazione pubblica e di giurisdizione applicabile, contenute nell’art. 12, d.lgs. 19 agosto 2016, n. 175, T.U. in materia di società a partecipazione pubblica, e l’espressa previsione all’art. 14 del citato T.U. della fallibilità di tali società hanno dato luogo al moltiplicarsi di azioni civili di responsabilità proposte dalla curatela del fallimento di società a partecipazione pubblica. Nel seno di simili azioni, esperite anche ex art. 2497 c.c. nei confronti dell’ente pubblico socio, la Cassazione si è da ultimo orientata, con le ordinanze a sez. un. del 13 settembre 2018, n. 22406, e …
