An unsupervised region growing method for 3D image segmentation
1995
The paper deals with 3D shape decomposition problem, objects are modelled as finite unions of almost-convex primitives. A new region growing method is proposed to extract meaningful objects parts. Parts are individuated by performing a set-partitioning of surface dominating points. The partition step returns labelled seeds from which to start a region growing procedure that propagate labels onto object surface patches. A fuzzy concept of λ-convexity is introduced to test noised real images. Experimental results are given.
Democracy in complex networks:political leaders and administrative professionals
2015
The core assumption in this chapter is that political actors and civil servants on the municipal level share in the common societal responsibility for the education and upbringing of the next generation. Using a filter of five core public-governance logics in the analysis of our data – the marketplace logic, the managerial, the public, the professional and the ethical –we find both similarities and differences between politicians and civil servants. We analyse how politicians and administrators are positioned in the system and how they develop their commitment to, and their competencies to take part in furthering, both a democratic education and an efficient and effective governance system,…
Distopía, eutopía y crisis social en el cine mainstream (Los casos de Los juegos del hambre y Del revés)
2018
espanolEn el marco de un mundo globalizado, la aparente "desideologizacion" que acompana a los bienes culturales actuales, sirve a los propositos de reproduccion del sistema capitalista, entendido este dentro de su vertiente cultural actual como un sistema omnipresente y omniabarcante. En este sentido, los productos culturales del mainstream estadounidense, continuan constituyendo, aun a dia de hoy, uno de los principales pilares a traves de los cuales el sistema se representa a si mismo, proponiendo y defendiendo determinados modos de vida, en concreto, el American Way of Life. En el actual contexto, el mainstream cinematografico, a traves de productos como “Los Juegos del Hambre” (The Hun…
Cost consciousness: conceptual development from a management accounting perspective
2015
Purpose – This paper aims to take note of the need to better understand cost consciousness from a management accounting perspective and serves as an exploratory study striving to analyze how the notion has been addressed by management accounting scholars. Design/methodology/approach – This paper presents the findings of a thorough literature review identifying the drivers, interpretations, definitions and results which management accounting scholars have associated with cost consciousness. Findings – This paper has synthesized the definitions and interpretations by considering their conceptual broadness and the subjects that cost consciousness characterizes. In addition, various potential …
Fostering Positive Changes in Health and Social Relationships in Children
2017
Several studies have demonstrated that altruism and gratitude may confer beneficial effects on psychophysical wellbeing. The present chapter describes how positive changes in health and social relationships can be fostered in 6- to 9-year-old children when participating in positive interventions. The findings show that the experience of working with others to attain shared goals and focusing on gratefulness positively modulated altruism and social interactions among peers, highlighting the great behavioural plasticity of children. Moreover, interventions involving cooperative playing not only increased positive relationships but also contributed to a decrease in chronic stress levels. The p…
Scalable Electro-Optic Control of Localized Bistable Switching in Broad-Area VCSELs Using Reconfigurable Funnel Waveguides
2017
We demonstrate a steplike optical modulation based on the activation and deactivation of a bistable localized structure using a photoinduced and reconfigurable miniaturized 30 × 30 μm electroactivated funnel waveguide. Control of a single 10-μm-diameter spot in a 200-μm-diameter vertical-cavity surfaceemitting laser at 980 nm is achieved modulating the phase of an exciting beam in the specific position of the spot in the cavity. This localized on-off response can be scaled into arrays and offer a possible route to fast integrated optical logical functions and memory at low intensities at near-infrared wavelengths.
A new ATLAS muon CSC readout system with system on chip technology on ATCA platform
2015
The ATLAS muon Cathode Strip Chamber (CSC) backend readout system has been upgraded during the LHC 2013-2015 shutdown to be able to handle the higher Level-1 trigger rate of 100 kHz and the higher occupancy at Run 2 luminosity. The readout design is based on the Reconfigurable Cluster Element (RCE) concept for high bandwidth generic DAQ implemented on the Advanced Telecommunication Computing Architecture (ATCA) platform. The RCE design is based on the new System on Chip XILINX ZYNQ series with a processor-centric architecture with ARM processor embedded in FPGA fabric and high speed I/O resources together with auxiliary memories to form a versatile DAQ building block that can host applicati…
Damage and fracture study of cold extrusion dies
2004
Abstract In the present paper die fracture in cold extrusion was investigated considering a few different die reduction zone geometries. A former finite element method (FEM) analysis of the process was developed to obtain the contact pressure distribution at the workpiece–die interface for each of the investigated geometries; subsequently a stress and strain analysis utilizing the BEM code Franc3D was carried out, with the aim to evaluate the crack propagation at each loading cycle, i.e. at each extrusion process. In this way the die life for each of the investigated extrusion die geometries was compared utilizing the Paris law and the values assumed by the stress concentration coefficient …
Emerging Standards and the Hybrid Model for Organizing Scientific Events During and After The COVID-19 Pandemic
2020
AbstractSince the beginning of 2020, the coronavirus disease (COVID-19) pandemic has dramatically influenced almost every aspect of human life. Activities requiring human gatherings have either been postponed, canceled, or held completely virtually. To supplement lack of in-person contact, people have increasingly turned to virtual settings online, advantages of which include increased inclusivity and accessibility and a reduced carbon footprint. However, emerging online technologies cannot fully replace in-person scientific events. In-person meetings are not susceptible to poor Internet connectivity problems, and they provide novel opportunities for socialization, creating new collaboratio…
Strappazzandola di parole ... maltrarrandola apiù un posso... Una lite tra fratello e sorella nella Sicilia di fine seicento
2019
La sfera domestica, nel passato come nel presente, è ?l?ambito privilegiato di espressione e di azione della violenza maschile contro le donne?. Nell?ultimo quarantennio gli studi su questo fenomeno di lunga durata e rappresentativo delle relazioni tra uomini e donne si sono moltiplicati. La violenza contro le donne si è rivelata un angolo visuale molto importante per riflettere su ?alcuni temi centrali nella storia europea: la famiglia, il potere, la civilizzazione? ed è oggetto di studio in diversi ambiti disciplinari, incluso quello storico. In questo articolo ho preso in esame la lunga contesa giudiziaria tra Anna Ruffo e il fratello maggiore Placido Ruffo, principe della Scaletta, prim…
