An anthracological approach to understanding Late Classic period cultural collapse in Mesoamerica’s northwestern frontier
2012
International audience; For over 50 years, researchers have suggested that increased regional rainfall over the highland deserts of Mesoamerica's northwestern frontier zone during the Classic period (AD 200-900) allowed for the colonization of the zone by farming groups who originated from Central and/or West Mexico. A severe and prolonged drought is hypothesized to have later provoked the abandonment of the region by these sedentary populations by AD 900. However, very little research has been carried out in the zone to detect evidence of this proposed climate change. I present results from the first systematic study of wood charcoal from the northwestern frontier, comparing the data from …
WATCHING PEOPLE: ALGORITHMS TO STUDY HUMAN MOTION AND ACTIVITIES
2020
Nowadays human motion analysis is one of the most active research topics in Computer Vision and it is receiving an increasing attention from both the industrial and scientific communities. The growing interest in human motion analysis is motivated by the increasing number of promising applications, ranging from surveillance, human–computer interaction, virtual reality to healthcare, sports, computer games and video conferencing, just to name a few. The aim of this thesis is to give an overview of the various tasks involved in visual motion analysis of the human body and to present the issues and possible solutions related to it. In this thesis, visual motion analysis is categorized into thr…
A innovative laterals hydro floating tilting systems for USV or surface nautical vehicles
2015
The proposed project shows the results obtained in the implementation and testing in lacustrine and marine environment of an innovative laterals hydro floating tilting systems control for USV or remote/autonomous surface nautical vehicles. This vehicle is based on a pending patent belonging to Palermo University (Patent Pending RM2012A000209 and RM2012A000209). The system allows, during operation as a vehicle USV, set changes sailing trim and make turns with very narrow angle with little shunting movements. In fact the main benefits obtained were able to change or adjust the navigation structure by changing the tilt of one or two hydro floating during navigation without intervening directly…
Self-assembly of 2,8,14,20-tetraisobutyl-5,11,17,23-tetrahydroxyresorc[4]arene
1999
We report herein the observation of a hexameric structure of a hydroxyresorc[4]arene in the solid state, enclosing a large interior space. This artificial molecular container is stabilized only by hydrogen bonds. The tendency to form aggregates in solution is demonstrated mainly by means of ESI-MS methods.
ASPECTOS CONFLITUAIS DOS CONTRATOS INTERNACIONAIS DE TRANSFERÊNCIA DE TECNOLOGIA: UMA ABORDAGEM IBERO-AMERICANA
2022
A tecnologia e a inovação são ativos importantes e elementos estratégicos que são singularmente competitivos a nível global para empresas e países, com um impacto direto no desenvolvimento econômico e social, bem como na sustentabilidade. Especialmente no atual ambiente altamente internacional, caracterizado pelos desequilíbrios no desenvolvimento tecnológico e no nível de inovação entre países e regiões. Uma importância que levou ao incentivo de políticas públicas ativas que têm impacto em sua promoção e na melhoria dos processos de gestão e transferência de tecnologia e inovação; tornando-se assim um setor chave com um caráter cada vez mais internacional. No âmbito Ibero-Americano, os aco…

« L’enfant à l’écran : une figure du résistant »
2008
Cet article est consacré au rôle de l’enfant dans des fictions espagnoles et hispanoaméricaines récentes, en particulier, dans El florido pensil (Juan José Porto, 2002) et dans la série télévisée Cuéntame como pasó. Nous tendons à mettre en lumière l’aspect ambigu de l’enfant en tant que figure de résistant, dans la mesure où il est, à la fois, emblématique d’une liberté que l’on veut opprimer, objet du regard bienveillant du spectateur et vecteur d’une certaine nostalgie de l’enfance et de l’innocence, y compris quand ladite époque coincide avec la dictature. Este artículo estudia el papel del niño en ficciones españolas e hispanoamericanas recientes, en particular El florido pensil (Juan …
Mother's and daughter's : interplay of physical activity with personal, behavioral, and environmental factors
2017
The purpose of this study was to explore the family dynamics in order to further understand and discover through interviews a parent and their children's behaviors in the topic area of physical activity choices. A narrative case study approach was taken to look into each family's experiences in order to better understand their motivations behind physical activity and to make conclusions of the social, environmental, and behavioral dynamics. Semi-structured interviews were completed with the parent and then with the child individually for a total of three families and four children. Family A is from South Korea living in Finland, family B is from Finland and living in Finland, family C is or…
