Backcalculation of airport pavement moduli and thickness using the Lévy Ant Colony Optimization Algorithm
2016
Interpretation of NDTdata is crucial in any Airport Pavement Management System (APMS), in order to implement strategies to maintain airport pavementssince they allow to estimate their remaining life and related maintenance needs and activities. In this paper, the AntColony Optimization algorithmwasused for backcalculation of pavement moduli from surface deflection data. The algorithm’s performances are illustrated and improvement in prediction quality is demonstrated both in terms of goodness of fitness and computational effort. Moreover, it is proved that the proposed algorithm is also able to predict layer thicknesses, taking into account their variation too.
Magnetic Resonance Imaging in Gastroenterology: Time to Say Good-bye to All That Endoscopy?
2000
Magnetic resonance imaging (MRI) has been described as the most important development in medical diagnosis since the discovery of the roentgen ray more than 100 years ago. The effectiveness of MRI has been extended to make it applicable in a wide variety of gastrointestinal disorders. The attention of gastroenterologists is currently focusing on pancreaticobiliary and bowel diseases. Magnetic resonance cholangiopancreatography (MRCP) has become a competitive alternative to diagnostic endoscopic retrograde cholangiopancreatography in a variety of hepatobiliary and pancreatic diseases. Magnetic resonance enteroscopy has the potential to become the preferable method for evaluating the entire s…
An Application of Ant Colony Optimization to Decision Making on Affective Virtual Entities
2007
Learning is a never ending activity for humans; it takes place everywhere and even when we do not realize. However, current learning environments make students deal with lectures, mostly associated with low control of the situation and implicit motivation. In contrast, previous researches have shown that sports, games or hobbies are activities that make people reach optimal experiences where self-motivation, control of the situation, high level of concentration and enjoyment are present. Some current efforts to design next generation of learning environments make use of ubiquitous systems to encourage students to perform learning activities everywhere and at anytime. However, those approach…
Utilidad de la TC-Colonografía como método de estadificación prequirúrgica del cáncer de colon
2018
- Introducción La correcta estadificación del cáncer de colon (CC) es fundamental para realizar la planificación del abordaje terapéutico en cada caso, y particularmente ante la posibilidad de aplicar nuevas terapias como el tratamiento con quimioterapia neoadyuvante en un futuro. Esto implica la necesidad de disponer de un sistema de estadificación preoperatoria sencillo y fiable, que identifique de forma precisa la localización y el estadio tumoral, que hasta la fecha, se ha realizado habitualmente mediante tomografía computarizada (TC) convencional. - Objetivos Evaluar la exactitud de la Colonografía-TC (CTC) para la determinación de la localización tumoral, del estadio tumoral (T), gang…
Failed Modernization of the Ethiopian State: Oromo Perspectives on Ethiopian Political Culture
2008
This article presents part of the qualitative data generated by the research "Ethnic relations in major towns around Addis Ababa: A comparative Study of the Dynamics of Social Solidarity", based in Addis Ababa University, College of Sociology and Social Administration, funded by the the Ethio-Italian University Co-operation Programme.
Transnational Political Activities of the Swedish Finn Youth Organization
2017
This article looks at the Swedish Finn Youth Organization’s transnational political activities, and how they have developed. In the beginning, the youth organization modelled itself after its mother organization and joined the Finnish Expatriate Parliament (FEP), which made its participation in transnational practices easy. The case study of the Swedish Finn Youth Organization in Stockholm, Sweden, demonstrates that if the younger generation is given an opportunity to establish and govern their own associations, new forms of organization can be expected. The younger generation has distinguished itself from the older generation’s associations by cooperating with other minorities and taking m…

Strategies for accelerating ant colony optimization algorithms on graphical processing units
2007
Ant colony optimization (ACO) is being used to solve many combinatorial problems. However, existing implementations fail to solve large instances of problems effectively. In this paper we propose two ACO implementations that use graphical processing units to support the needed computation. We also provide experimental results by solving several instances of the well-known orienteering problem to show their features, emphasizing the good properties that make these implementations extremely competitive versus parallel approaches.
Fanon, “Profeta del Terzo Mondo unitario”, e la “crisi” dell’antropologia
2018
The essay is inspired by the works of Frantz Fanon, Martinican psychiatrist and revolutionary man, prematurely disappeared in 1961, who became, in Italy too, between the years 1968 and 1970, an icon of the youth protest movement, of the anti-racist organizations and of the liberation movements. His short but intense life developed between a theoretic production (on the psychiatry of the colonised subject and on racism) and his personal political commitment for the liberation of colonized countries. He supported, and became its spokesman, the Algerian National Liberation Front during the Algerian War. The recent re-printing of some of his works and the large quantity of foreign articles publ…
Gaspare Ambrosini. Dal fascismo all’invenzione dell’autonomia siciliana
2018
This work traces the work of Gaspare Ambrosini (1886-1985) along three different ones Italian political systems of the twentieth century: liberal, fascist and republican. In each of these three epochs, Ambrosini played a leading role not only from the point of view of intellectual reflection and of the academic profession, but above all in that of militant political commitment. His is the first innovative reflection on the birth of the system of mass parties after the introduction of suffrage universal (male) immediately after the great war; his is the elaboration of the one-party system fascist; his is the creation of the first systematization of imperial and racist theories after the conq…
