Novel algorithms for 3D surface point cloud boundary detection and edge reconstruction
2019
Abstract Tessellated surfaces generated from point clouds typically show inaccurate and jagged boundaries. This can lead to tolerance errors and problems such as machine judder if the model is used for ongoing manufacturing applications. This paper introduces a novel boundary point detection algorithm and spatial FFT-based filtering approach, which together allow for direct generation of low noise tessellated surfaces from point cloud data, which are not based on pre-defined threshold values. Existing detection techniques are optimized to detect points belonging to sharp edges and creases. The new algorithm is targeted at the detection of boundary points and it is able to do this better tha…
Tailoring PLLA scaffolds for tissue engineering applications: Morphologies for 2D and 3D cell cultures
2009
PLLA scaffold suitable for dermis regeneration were realized by Thermally Induced Phase Separation (TIPS) starting from a ternary solution PLLA/dioxane/water. The reconstruction of a complex tissues as the dermis implies the use of different cellular types (coculture), with different growth behaviour (2D vs. 3D). The scaffolds present an homogeneous porous surface to allow the keratinocytes 2D growth and a porous internal structure for the fibroblasts 3D growth. Our results show that the porosity of the surface can be tuned by changing the chemical nature of the sample holder (aluminium, teflon, polypropylene). A large variety of morphologies, in terms of average pore size and interconnecti…
Innovating European Long-Term Care Policies through the Socio-Economic Support of Families: A Lesson from Practices
2022
LTC and socio-economic deprivation of families are two relevant issues in international debate. The economic or time investment made by families in caregiving has an impact on the socio-economic status of family members in terms of economic means and social inclusion. This study analyzes the practices that are supported by home LTC, examining their characteristics, identifying their strengths, weaknesses, drivers, and barriers, as well as identifying social innovation aspects. The study provides a qualitative interpretative comparison of 22 practices from eight countries, representing the four LTC care models existing in Europe. Cross-studies aid in the development of sustainable policies. …
Il ponte delle Teste sul fiume Oreto
2015
Il fortuito ritrovamento al di sotto del terreno di riporto, di un antico ponte in muratura ancora perfettamente integro, ha sollecitato una ricerca sull’epoca e le tecniche di costruzione adottate. Attraverso l’analisi delle fonti antiche, della cartografia attuale e storica, delle cronache del tempo si è delineata la storia del sistema di attraversamento del fiume Oreto, l’espansione della città fino all’area del ponte, ritrovando quelle pratiche sociali che hanno fatto attribuire il nome non consueto. Lo studio ha inoltre ripercorso le vicende costruttive delle diverse strutture che si sono susseguite nel sito, dalla fine del XVI secolo a pochi anni addietro. Si sono ritrovate informazio…
Development of a questionnaire to assay recalled liking for salt, sweet and fat
2012
Abstract Liking for a sweet, salty or fatty diet may induce overconsumption of simple carbohydrates, sodium or lipids. Measuring overall liking of the corresponding sensory sensations contributes to understanding the determinants of dietary behaviours. However, no standardized validated questionnaire assaying these sensations is currently available. In the present study, we developed a web-based questionnaire, “PrefQuest”, which measures recalled liking for the following four sensations: salt, fat and salt, sweet, fat and sweet. PrefQuest included four types of items: (1) liking for sweet, fatty-sweet and fatty-salty foods, (2) preferences in the level of seasoning by adding salt, sweetener…
Quasi-brittle porous material: Simulated effect of stochastic air void structure on compressive strength
2021
Abstract The effect of porosity comprised of spherical air voids on the compressive strength of quasi-brittle material was studied via simulations. The simulated porous structures were based on pore size distributions of two mortar samples measured by X-ray microtomography. While the simulation method set practical limits on the size of sample, the base of the statistics was established by simulating 128 small structures generated by sampling from pore structures of two mortars. By studying the application of the classical strength-porosity formulas to the simulated data, a new simple model was formed. A linear relationship was achieved between the cubic root of air void fraction (porosity)…

Measuring International Competitiveness of Romania by Using Porter's Diamond and Revealed Comparative Advantage
2013
Abstract International competitiveness generate a number of challenges because creates profitability for companies, welfare for citizens, sustainable prosperity for the economy as long as it is perceived as a constructive concept. The aim of present paper is to identify the international competitiveness of Romania by analyze the competitive advantage and disadvantage according to Porter‘s Diamond, on one hand, and by calculate revealed comparative advantage according to Balasa, on the other hand. The results show that Romanian has more competitive disadvantage than competitive advantage, even if by comparison with European Union, Romania has some revealed comparative advantage.
Visits to Natural Environments Improve State Body Appreciation: Evidence from Malaysia, Romania, and Spain
2020
Recent studies have reported that nature exposure is associated with more positive body image—a multifaceted construct that includes one's body-related thoughts, feelings, and behaviors—but these studies are constrained by a focus on limited national contexts and environment types. To rectify this, we examined the impact of nature exposure on state body image in diverse national contexts and across different environment types. In Study 1, 140 Romanian and 161 Spanish adults who visited botanic gardens were asked to complete a measure of state body appreciation on entry and again upon exit, as well as report their visit duration. Analyses indicated that there was a significant increase in bo…
