Abstract The aim of this work is to present a formulation to solve the one-dimensional Ising model using the elementary technique of mathematical induction. This formulation is physically clear and leads to the same partition function form as the transfer matrix method, which is a common subject in the introductory courses of statistical mechanics. In this way our formulation is a useful tool to complement the traditional more abstract transfer matrix method. The method can be straightforwardly generalised to other short-range chains, coupled chains and is also computationally friendly. These two approaches provide a more complete understanding of the system, and therefore our work can be o…
Outlining the Limits of Friction Stir Consolidation as Used as an Aluminum Alloys Recycling Approach
2021
Friction stir consolidation (FSC) is a solid-state process that recycles metal scraps economically and eco-friendly compared to the conventional melting method. The process parameters especially processing time and rotational speed, have a crucial role in achieving a sound disc during FSC. The current study answers the research question of how far these process parameters can be effective when the mass of chips to be recycled increases. In specific, an experimental setup was analyzed that was previously identified as challenging for recycling 20 g chips of aluminum alloy AA 2024-O. Rotational speed was set doubled, and processing time was increased up to 1.5 times of their initial values. T…
Spatial fragmentation of, and US support for, the main multilateral institutions of the western order
2017
The growth of China-led minilateral initiatives mostly of a regional character has challenged the main multilateral institutions of the Western order and, ultimately, US authority. Faced with a progressive delegitimation of the institutional architecture that it promoted after World War II, the US, under the Obama administration, has acted to defend the existing main multilateral institutions of the order (UN, IMF, WB and WTO), attributing them with a strategic role. More than being radical, though, the reforms enacted have been incremental and pragmatic, but always imperfect. More importantly, they have not altered US influence, which is exercised mostly through informal means. This, howev…
Puhekaverina botti
2020
Viestivät tekoälyt eli luonnollisella kielellä käytävään keskusteluun kykenevät algoritmit ovat yhä tyypillisempiä vuorovaikutuskumppaneita erilaisilla teknologisilla alustoilla. Yksi tyypillinen viestivän tekoälyn muoto on botti: automaattinen ohjelma, joka käyttää verkkopalvelun käyttäjätiliä tavallisen käyttäjän tavoin ja suorittaa yksinkertaisia toimintoja tai viestii. Tyypillisesti botit tavalla tai toisella pyrkivät näyttäytymään ihmiskäyttäjinä, tai ainakin niille ohjelmoidaan ja suunnitellaan ihmisenkaltaisia piirteitä.Artikkeli tarkastelee bottien roolia vuorovaikutuskumppaneina sisäisessä ja julkisessa mediatilassa kytkeytymällä tuoreeseen ihmis-koneviestinnän tutkimusalaan.

Customizing Semantic Profiling for Digital Advertising
2014
International audience; Personalization is the new magic buzzword of application development. To make the complexity of today's application functionalities and information spaces "digestible", customization has become the new go-to technique. But while those technologies aim to ease the consumption of media for their users, they suffer from the same problematic: in the age of Big Data, applications have to cope with a conundrum of heterogeneous information sources that have to be perceived, processed and interpreted. Researchers tend to aim for a maximum degree of integration to create the perfect, all-embracing personalization. The results are wide-range, but overly complex systems that su…
The impact of noise estimation on dehazing
2020
International audience; Under haze or fog, the quality of the images is degraded due to the atmosphere, causing the details of the images to be difficult to identify by observers and computer vision systems. Such images contain noise, which is mainly due either to environment (extrinsic noise) or sensor (intrinsic noise). As the transmission of light coming from the scenes' objects is exponentially attenuated and comes quickly down to zero in presence of haze, the noise is greatly amplified at high haze densities and long distances. In order to investigate the importance of the accurate estimation and the removal of noise from hazy images, we used the CHIC (Color Hazy Image for Comparison) …
Les phiales étrusques de type Vetulonia/Colmar de la tomba del carrettino à Ca’ Morta (Côme, Italie) : essai de contre-typologie.
2021
AbstractA new study of the patere baccellate from the Tomba del carrettino at Ca’ Morta offers the opportunity to re-examine the typology of the ribbed bowls of Vetulonia/Colmar type and to re-evaluate their funerary contexts. These vessels appear in central and southern Etruria at the end of the eighth and the beginning of the seventh century BC, the site of Vetulonia being considered as their main production site.Ferdinando Sciacca’s (2005) classification of the ribbed bowls of Vetulonia/Colmar type is supported by solid evidence ; it has advanced the subject significantly, but Sciacca’s model nevertheless raises some questions in terms of the hierarchy of the criteria that were chosen.Du…
Les enquêtes client mystère : un dispositif de gestion au service des transformations organisationnelles ou comment réorganiser l'entreprise " au nom…
2012
The mystery shopping technique is a tool frequently used by organizations to hit a double target: (1) to seduce/to reassure/ to make the customer regular; (2) to diffuse the customer's voice in the organization and to justify the change. Although a great diffusion of the mystery shopping in private and public organizations, there are few studies on this tool. From the SNCF's example, the author considers the mystery shopping from the foucaldian point of view as a management mechanism in order to support organizational changes and analyses the effects of power induced by this tool.

L'influence du format d'e-publicité et de l'intrusion perçue sur les attitudes envers le format, l'annonce, la marque et envers le site internet supp…
2012
This research builds on Anzieu's works (1994) to define intrusiveness concept and the persuasion theory to predict that an ad format and, besides, the perceived intrusion can have an impact on attitudinal responses. The results show that the use of some format of advertising leads intrusion perception. Furthermore, the perceived intrusion influence negatively attitude toward format, ad and brand. This perception is a mediator partial in the relation between the format and attitude toward format and a mediator total between the format and the attitude toward ad.
