Federico Barnabè
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.326152
Abstract: This work takes into consideration the wide reform process that is impacting on Universities all over the world, especially focusing on the public versus private funding debate for Higher Education Institutions. In this regard, the paper provides some considerations on possible funding sources, discusses data related to the relevance of public funding and presents the features of the main models of public funding across many countries, particularly focusing on Europe.
Les polémiques autour de la littérature jeunesse, ou la quête sans cesse rejouée de la légitimité
Fanny Barnabé
COnTEXTES : Revue de Sociologie de la Littérature , 2012, DOI: 10.4000/contextes.5020
Abstract: IntroductionLa polémique dont il sera question ici a débuté suite à un article de Fran ois Busnel, publié le 24 novembre 2010 dans l’Express-Lire, dans lequel ce dernier dénigrait la littérature jeunesse et l’accusait de n’être qu’un coup marketing , pour ensuite faire la promotion du livre de Danièle Sallenave Pourquoi on écrit des romans. Cette attaque fut très mal re ue par les auteurs, éditeurs et libraires de littérature jeunesse, et déclencha un certain nombre de réponses, dont la pr...

Abstract: We shall examine how Hobbes conceives the international relations as a scenario of permanent hostility, his contribution to the realist theory of international relations and the strategies for the attainment of peace or the maximization of benefits. We shall investigate the hobbesian equation between state of nature, international relations and state of war, the characteristics of the state of nature, the properties of foreign war and its causes, and the mechanism of balance of power. We shall also analyze the natural law, which is the law of nations, and the calculation to adhere to these laws. Finally, we shall do a general analysis of Hobbes's contribution to the theory of international relations. Examinaremos como Hobbes concebe as rela es internacionais enquanto um cenário de permanente hostilidade, sua contribui o para a teoria realista das rela es internacionais e as estratégias para a consecu o da paz ou a maximiza o dos benefícios. Investigaremos a equa o hobbesiana entre estado de natureza, rela es internacionais e estado de guerra, as características do estado de guerra, as propriedades da guerra externa e suas causas e o mecanismo de balan o de poder. Analisaremos, também, a lei natural, que é a lei das na es, e o cálculo para aderir a essas leis. Por fim, faremos uma análise genérica da contribui o de Hobbes para a teoria das rela es internacionais.
The poetics of the natural light in the work of Oscar Niemeyer A poética da luz natural na obra de Oscar Niemeyer
Paulo Marcos Mottos Barnabé
Semina : Ciências Sociais e Humanas , 2002,
Abstract: This article deals with the use of natural light as a project line in the work of Oscar Niemeyer. This is an element that, as it is conditioning techniques, becomes a matter of architecture itself, providing answers to questions of function and also being shaped to cause emotion. Therefore, considerations are made about lightning events in significant buildings in the history of architecture; about the conceptual setting on which Niemeyer’s discourse is based; and about the analysis of some of his works. Finally, a demarcation is established as to the main concepts concerning the theme of light and the constructed and experienced objects. O artigo versa sobre o uso da luz natural como diretriz de projeto na obra de Oscar Niemeyer. Elemento que, superando condicionantes da luminotécnica, torna-se matéria própria da arquitetura, respondendo às quest es funcionais mas também sendo moldada para emocionar. Para tanto, faz-se considera es sobre acontecimentos lumínicos em edifícios emblemáticos da história da arquitetura, sobre o cenário conceitual que norteia o discurso de Niemeyer, e sobre a análise de algumas de suas obras. Finalmente, elabora-se um balizamento entre os principais conceitos relacionados à temática da luz e aos objetos construídos vivenciados.

A General Purpose Analysis Package  [PDF]
Stefano Federico
Atmospheric and Climate Sciences (ACS) , 2012, DOI: 10.4236/acs.2012.22022
Abstract: This paper presents a general-purpose analysis package able to solve two- and three- dimensional analysis problems. The system can use the following methods of solution: Successive Approximation (SA), Optimal Interpolation (OI), and 3D-Var. Analyses are given for the following parameters: zonal and meridional wind components, temperature, relative humidity, and geopotential height. The analysis package was applied to produce analyses at 6 h time interval for the period 1-11 August 2008. The period was selected for data availability and forty-one analyses were collected. The results show the validity of the different solutions, which can be chosen depending on the physical problem to solve and on the computational resources available. In particular, assuming the observations as the reference, all solutions show a decrease of the RMSE compared to the background. The decrease is consistent with the particular setting of the analysis system used in this paper. The comparison between different solutions shows that the SA converges to OI in few iterations, and that the SA solution with ten iteration is, in practice, equal to OI. Moreover, the 3D-Var method shows its potential to improve the analysis, once the horizontal and vertical length-scales and the background and observational errors are set optimally, because its solution may be sizeably different from two-dimensional methods.
Preliminary Results of a Data Assimilation System  [PDF]
Stefano Federico
Atmospheric and Climate Sciences (ACS) , 2013, DOI: 10.4236/acs.2013.31009

A data assimilation system combines all available information on the atmospheric state in a given time-window to produce an estimate of atmospheric conditions valid at a prescribed analysis time. Nowadays, increased computing power coupled with greater access to real-time asynoptic data is paving the way toward a new generation of high-resolution (i.e. on the order of 10 km) operational mesoscale analyses and forecasting systems. Moreover, better initial conditions are increasingly considered of the utmost importance for Numerical Weather Prediction (NWP) at the short range (0 - 12 h). This paper presents a general-purpose data assimilation system, which is coupled with the Regional Atmospheric Modelling System (RAMS) to give the analyses for: zonal and meridional wind components, temperature, relative humidity, and geopotential height. In order to show its potential, the data assimilation systems applied to produce analyses over Central Europe. For this application the background field is given by a short-range forecast (12 h) of the RAMS and analyses are produced by 2D-Var with 0.25? horizontal resolution. Results show the validity of the analyses because they are closer to the observations, consistently with the settings of the data assimilation system. To quantify the impact of improved initial conditions on the forecast, the analyses are then used as initial conditions of a short-range (6 h) forecast of the RAMS model. The results show that the RMSE is effectively reduced for the one- and two hours forecast, with some improvement for the three-hours forecast.

Photovoltaic Prickle Pear Harvesting Tool  [PDF]
Federico Hahn
Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.43033

Mexico is the largest cactus exporter of the world and 40% of the production cost is provided from the harvest operation. Many workers are required to operate daily and suffer wrist pain after two weeks of collecting pears with mechanical pruners. A motor driven tool supplied from a photovoltaic system was employed for harvesting; different blades were tested at different cutting speeds. It was found that toothed blades sliced the pears with efficiencies over 90%. Abrasive blades were finally selected as the current required per cut was minimum, permitting a longer battery lifetime before requiring recharging.

One Dimensional Relativistic Particle in a Quadratic Dissipative Medium Subjected to a Force That Depends on the Position  [PDF]
Federico Petrovich
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.69122
Abstract: We will find a constant of motion with energy units for a relativistic particle moving in a quadratic dissipative medium subjected to a force which depends on the position. Then, we will find the Lagrangian and the Hamiltonian of the equation of motion in a time interval such that the velocity does not change its sign. Finally, we will see that the Lagrangian and Hamiltonian have some problems.
A New Formulation of Classical Mechanics—Part 1  [PDF]
Federico Petrovich
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.42048
Abstract: This paper has two parts, in this occasion we will present the first one. Until today, there are two formulations of classical mechanics. The first one is based on the Newton’s laws and the second one is based on the principle of least action. In this paper, we will find a third formulation that is totally different and has some advantages in comparison with the other two formulations.
