Autorreflexión pedagógica
2019
The autobiographical reflection on school learning makes it possible to explain how personal life guidelines are loading teaching activity with experiences. Educational time does not consist only of a linear narration, but works as the evocation of temporal and spatial memories of an explanation of the present. Personal life is intertwined with school reflection to give meaning to what we decide from teaching
Reverse Catmull-Clark Subdivision
2006
Reverse subdivision consists in constructing a coarse mesh of a model from a finer mesh of this same model. In this paper, we give formulas for reverse Catmull-Clark subdivision. These formulas allow the constructing of a coarse mesh for almost all meshes. The condition for being able to apply these formulas is that the mesh to be reversed must be generated by the subdivision of a coarse mesh. Except for this condition, the mesh can be arbitrary. Vertices can be regular or extraordinary and the mesh itself can be arbitrary (triangular, quadrilateral…).
Ositusmetodit reaaliaikaisessa renderöinnissä
2017
Tietokonegrafiikka ja siihen liittyvät menetelmät ovat nopeasti kehittyvä tutkimuksen ala. Tämän tutkimuksen tavoitteena on pohtia eri ositusmenetelmien toimintaa reaaliaikaisessa käytössä sekä vertailla näitä menetelmiä. Nykyaikaiselle käytölle tehokkaimmaksi osoittautui kolmesta tutkitusta menetelmästä tuorein (Brainerd ym. 2016). Tulevassa tutkimuksessa laitteistointegraatioon keskittyminen voisi tuoda ositusmenetelmät nopeammin kuluttajien saataville.

The latest of the three studied methods turned out to be…
Holocene Spatiotemporal Redox Variations in the Southern Baltic Sea
2021
Low oxygen conditions in the modern Baltic Sea are exacerbated by human activities; however, anoxic conditions also prevailed naturally over the Holocene. Few studies have characterized the specific paleoredox conditions (manganous, ferruginous, euxinic) and their frequency in southern Baltic sub-basins during these ancient events. Here, we apply a suite of isotope systems (Fe, Mo, S) and associated elemental proxies (e.g., Fe speciation, Mn) to specifically define water column redox regimes through the Baltic Holocene in a sill-proximal to sill-distal transect (Lille Belt, Bornholm Basin, Landsort Deep) using samples collected during the Integrated Ocean Drilling Program Expedition 347. At…
A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN LOWER LIMB: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF M…
2020
The aim of this Article is to show methods for dissection of the lower limb. In the summer 2017 a group of students at the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta - School of Medicine. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. This paper presents the results of the dissection course and a small and simple guide to young students and medical doctors who want to learn the bases of lower limb dissection.
Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data
2019
The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-density 90K SNP panel. We estimated the levels of molecular diversity and described population structure, which r…
ChemInform Abstract: Cyclic SiS2: A New Perspective on the Walsh Rules.
2012
Cyclic SiS2 is detected in the low-current dc discharge products of a mixture of SiH4 and H2S by Fourier transform microwave spectroscopy.
Regional differences in Italian students' performance: a simulation model
2017
This work presents the first results of a research project seeking to build a simulation model able to reproduce the differences of Italian students’ performance at regional level. A preliminary qualitative cause-and-effect model defines the main variable involved in the inter-generational skill formation processes, as well as their interplay with the job market context and the triggering of motivational forces for new skill acquisition. Such model was designed according to a system dynamics perspective, considered suitable for capturing the interrelatedness of key variables and for providing useful simulation tools to conduct and communicate future scenario analyses. Keywords: regional…
A dynamic performance management approach to support local strategic planning
2015
In spite of efforts devoted in the last decades to local strategic planning, such field of research and practice has been frequently characterized by a lack of implementation. We argue here that this phenomenon is due to the limitations of the static and linear approach to local strategic planning in fostering the development of common shared view among policy makers on the relevant system's structure and behavior. By means of a case-study, we illustrate how an approach based on system dynamics modeling applied to Performance Management can be useful to overcome such weaknesses. The proposed approach enhances a better understanding of the causes and effects related to adopted policies, unde…
Use of driving simulators for advanced driver assistance Systems evaluation in emergency situations
2012
Introducing advanced driver assistance systems in cars has numerous consequences, particularly on drivers' behavior and their interaction with the vehicle. The expected safety benefits of assistance systems can thus be jeopardized. In order to assess the actual safety benefits, driving simulators offer a safe and cheap alternative. This doctoral work relies on experiments carried out on driving simulators with different assistance systems. A first experimental part focuses on longitudinal control assistance: we studied drivers' familiarization with a Forward Collision Warning system in critical situations. A second experimental part focuses on lateral control assistance: we studied drivers'…
