Luttes nationales et politique étrangère
Authors: Pouponneau Florent
Published: October 2013

Durant l’été 2007, en rupture avec les pratiques diplomatiques menées depuis 2003, le gouvernement français promeut l’idée de sanctions contre l’Iran en dehors du Conseil de sécurité dans le cadre de sa politique de non-prolifération nucléaire. L’analyse cherche à rendre compte de cette évolution de la « position de la France » en examinant, à partir d’entretiens et d’archives, la configuration nationale où s’élabore cette politique de l’État. L’enquête identifie un clivage central au sein du Quai d’Orsay entre les diplomates responsables des relations bilatérales avec l’Iran et ceux en charge des questions atomiques. Ces derniers peuvent néanmoins compter sur l’institutionnalisation d’une « communauté non-prolifération » au sein et aux marges de l’appareil d’État pour constituer le programme nucléaire de l’Iran en « problème » et disqualifier les non-spécialistes. Ils bénéficient en plus de l’élection d’un chef de l’État qui tient à afficher sa proximité avec la politique américaine. L’analyse des alliances internationales dont bénéficient les acteurs étudiés nous conduit cependant à adopter un point de vue non décisionniste sur la politique étrangère.

Syndicats contre coopératives ? L'Organisation internationale du travail et la représentation des acteurs de la société civile
Authors: Louis Marieke
Published: October 2013

En 1919, l’Alliance coopérative internationale fait part à Albert Thomas, directeur général du Bureau international du travail, de son désir de voir l’Organisation internationale du travail (OIT) comprendre des représentants des organisations coopératives de chaque pays, au même titre, que les États et les syndicats ouvriers et patronaux. À peine l’OIT est-elle créée et son tripartisme célébré comme une innovation majeure qu’ils sont donc remis en cause. Cet article examine les conditions de l’éviction du mouvement coopératif de l’OIT, la revendication du mouvement coopératif international pour une « représentation directe et séparée » au sein de l’organisation ainsi que la mise en place de dispositifs, entre 1919 et 1948, qui aboutissent à créer une relation consultative entre lui et l’OIT avant l’obtention du statut consultatif proprement dit.
Amitié « latine » et pragmatisme diplomatique. Les relations franco-italiennes de 1936 à 1938
Authors: Poupault Christophe
Published: October 2013

De la fin de la guerre d’Éthiopie en mai 1936 jusqu’à l’automne 1938, les relations franco-italiennes, qui s’étaient largement améliorées après les accords de Rome de janvier 1935, se dégradent. Les choix diplomatiques du Front populaire, la non-reconnaissance par la France du nouvel Empire d’Italie, la guerre d’Espagne et le rapprochement italo-allemand rendent les conversations officielles de plus en plus rares tandis que les crises internationales qui se multiplient accroissent les divergences. Le thème de la « latinité », longtemps utilisé dans les deux pays pour légitimer une entente, ne séduit plus. Grâce aux efforts des organisations favorables à une réconciliation, le contact n’est jamais rompu mais la hantise de la rupture est bien présente durant une période où la destruction de l’amitié franco-italienne favorise le basculement des alliances.
Une délégation patronale française en Chine communiste pendant la guerre froide : la mission économique Rochereau de 1956
Authors: Robin Thierry
Published: October 2013

Dans un contexte international très défavorable, la France, qui n’a pas reconnu la République populaire de Chine, ne dispose pas, en outre, de cadre économique ou financier global pour ses échanges avec cet État. Afin d’y remédier, une délégation est envoyée à Pékin par le patronat français, au début de 1956. Dirigée par Henri Rochereau, elle est la première mission commerciale en Chine communiste à disposer du soutien, officieux, du Gouvernement français. L’article s’intéresse à la préparation, au déroulement et aux résultats de cette mission, dont le mérite, au-delà de ses résultats proprement commerciaux, est d’aboutir à la signature d’accords de paiements et à la mise en place de nouvelles règles commerciales avec la RPC.
« Je suis plus prudent que de Gaulle. » François Mitterrand et la diplomatie américaine, 1972-1981
Authors: Heurtebize Frédéric
Published: October 2013

Sans chercher l’ imprimatur des dirigeants américains, François Mitterrand tenta de dédramatiser les conséquences d’une participation de ministres communistes au sein d’un éventuel gouvernement d’Union de la gauche. À Paris, il bénéficia d’une ambassade américaine globalement progressiste prompte à voir en lui l’artisan du déclin du PCF. À Washington, en revanche, l’arrivée possible des communistes au pouvoir dans un pays d’Europe de l’Ouest était source d’inquiétude. Pour atténuer l’hostilité de l’exécutif américain, notamment sous Nixon et Ford, Mitterrand se contenta d’initiatives individuelles spontanées de dirigeants socialistes qui, lors de séjours aux États-Unis, s’efforcèrent de minimiser le pouvoir de nuisance du PC. Sous Carter, les socialistes entretinrent des relations chaleureuses avec certaines figures clés de l’administration. Si leur action n’eut pas d’effets immédiats, ils s’avérèrent fructueux in fine.
Aux origines de la diplomatie européenne : Les Neuf et la Coopération politique européenne de 1973 à 1980
Authors: Găinar Maria
Published: October 2013

La mise en place de la Coopération politique européenne (CPE) dans les années 1970 permet de franchir une étape importante vers l’union politique qui est considérée depuis toujours comme l’objectif final de l’intégration européenne. La CPE se fonde sur les deux rapports Davignon, adoptés en 1970 et en 1973. Elle concerne le domaine souverain de la politique étrangère et elle s’appuie sur un mécanisme de nature intergouvernementale. La CPE se fait donc avec les États membres des Communautés européennes, mais en dehors du cadre communautaire. Plusieurs facteurs marquent son évolution entre 1973 et 1980. D’abord les acteurs, et en premier lieu, les neuf pays impliqués. Comme les acteurs étatiques jouent un rôle déterminant, il faut avoir à l’esprit les différences qui existent à l’origine entre les politiques étrangères des Neuf, mais aussi entre leurs traditions et leurs cultures politiques. Les cadres dans lesquels la CPE évolue ont également une influence importante, en particulier le processus de la construction européenne et l’échiquier international dominé par les États-Unis et l’Union soviétique. C’est en prenant en compte ces éléments que la Coopération politique est analysée au temps des Neuf dans son fonctionnement et sa capacité tant à affirmer le rôle de l’Europe dans le monde, notamment par le biais de la déclaration sur l’identité européenne, qu’à faire entendre la voix des Neuf sur différentes questions internationales comme la CSCE ou le Proche-Orient.
L'ambiguïté de l'identité japonaise en relations internationales et la montée en puissance de la Chine : la fin du pacifisme constitutionnel ?
Authors: Boulanger Éric
Published: October 2013

Depuis la Restauration de Meiji (1868), l’identité du Japon en relations internationales est frappée du sceau de l’ambiguïté. Celle-ci tire son origine de la connexion difficile de deux visions du monde, l’une occidentale et l’autre japonaise. Les oligarques de Meiji ont choisi la modernité en conservant un système d’autorité traditionnel. Pour comprendre le système international de leur époque, ils ont utilisé un schéma cognitif qui s’inspirait de la structure de pouvoir du bakufu (gouvernement militaire) d’Edo qui a donné naissance à une longue « paix kantienne ». Ce texte reprend ce schéma cognitif qui a profondément influencé la pensée politique nipponne pour en faire une analogie à caractère historique en mesure de nous éclairer sur l’ambiguïté identitaire du Japon en relations internationales, de Meiji à aujourd’hui, alors qu’il doit repenser son pacifisme constitutionnel pour affronter la puissante montante de la Chine.

El impacto de la violencia anticlerical en la primavera de 1936 y la respuesta de las autoridades
Authors: Álvarez Tardío Manuel , Villa García Roberto
Published: October 2013

Este artículo analiza el alcance y las características de la violencia anticlerical en los meses de febrero a junio de 1936. Se han rastreado diferentes fuentes primarias para realizar una estadística lo más precisa y completa posible de esa violencia. Primero, se analiza el contexto en el que ésta tuvo lugar. Segundo, se presentan los datos resultantes de la investigación cuantitativa y cualitativa de la violencia anticlerical. Y tercero, se plantea cuál fue la respuesta de las diversas autoridades ante ese fenómeno. El artículo prueba que los datos sobre violencia anticlerical que se han manejado hasta ahora eran fragmentarios y no contemplaban la magnitud ni el carácter general que llegó a alcanzar en los meses inmediatamente anteriores a la Guerra Civil. Además, demuestra que la reacción del gobierno fue, como poco, ambivalente, no correspondiéndose con las promesas de salvaguardar la legalidad que formuló en privado a la Nunciatura. En muchos casos la violencia anticlerical se produjo ante la pasividad de la policía y/o con la complicidad de las autoridades locales o algunos grupos afines a la coalición que sostenía parlamentariamente al gobierno central.

Authors: Shi Jian Jun , Cheng Zhi Qiang , Gelin J.C. , Liu Bao Sheng , Barrière Thierry
Published: October 2013

In order to improve the accuracy of numerical simulation for injection molding process, a modified method for outlet condition was introduced. As the feedstock is regarded as incompressible fluid, the filling ratio should be a linear one with respect to time. But there remains a persistent trouble in previous researches that the linearity is not respected when the filling front approaches near the outlet boundary. The problem is caused by lack of adequate treatment on the outlet boundary. To remedy this defect, the present paper deals with the modeling and realization of suitable condition on outlet boundary for solution of the whole filling process. A simple straight channel mold was taken as an example to prove the proposed simulation method. The result shows that this modified method can suppress the distortion phenomenon and can be valid to realize the correct simulation for the filling of incompressible viscous flow at the ending stage. This long-term filling problem was finally solved.
An Information Fusion Algorithm Based on Kalman Filtering
Authors: Tan Xiu Hu
Published: October 2013

For the multisensor systems with unknown noise variances, by the statistics method, the mathematical model and the noise statistics are essential, and this limitation was settled by adaptive algorithm. The adaptive Kalman filter was proposed to solve the filtering problem of the system with unknown mathematical model or noise statistics in information fusion. Based on the probability method and the scalar weighting optimal information fusion criterion in the minimum variance sense, the algorithm can not only optimize the multi-channel data, but also obtain the minimum mean square error (MMSE) by introducing fusion equation, namely the algorithm is optimal under the sense of MMSE, and the error is the least than the original Kalman information fusion algorithm. The test result shows that the algorithm can precede information fusion effectively under the distributed acquisition system.

Published: October 2013

To simulate biological activities of human visual system, we propose a curvelet-based image fusion method using unit-linking pulse coupled neural networks (ULPCNNs) model. Contrasts of detailed coefficients are inputted into the ULPCNNs to imitate the sensitivity of HVS to detailed information, and the contrasts are also employed as corresponding linking strength for the neurons. After motivated by external stimuli from images, ULPCNNs can produce series of binary pulses containing much information of global features. Then we use the average firing times of output pulses in a neighborhood as the salience measure to determine our fusion rules. Experimental results demonstrate that, our proposed method has a satisfying fusion result both on visual effects and objective evaluations.

Bending Analysis of Carbon Nanotubes Based on Analytical Nonlocal Timoshenko Beam Model
Authors: Yang Yang
Published: October 2013

Based on nonlocal elastic continuum theory, a new mathematical model and analytical solutions for nonlocal Timoshenko beam model (ANT) is established according to Hamiltons principle. Shear deformation and nonlocal effect are considered in the ANT model. The new ANT equilibrium equations and boundary conditions are derived for bending analysis of carbon nanotube (CNT). The bending behaviors of CNT with simply supported and cantilever boundary conditions are solved and discussed. The ANT deflection solutions demonstrate that the CNT stiffness is enhanced by the presence of nonlocal stress effects. Furthermore, the new ANT models concluded verifiable bending behaviors for a cantilever CNT with point load at the free end, which depends on the strength of nonlocal stress. This new conclusion reverts the current understanding according to the common nonlocal models adopted today, that the deflection in this case is indifferent to stress nonlocality and thus it surprising behaves like a macro beam with classical beam bending solution without size effect.

As one of the most important structures of throttling and pressure limiting, orifice plays a significant role in flow control of the whole system. The existing empirical correlation was improved by correction on characteristics of low Reynolds number and compressibility. Then, improved one-dimensional analytical model of rotating long orifice with chamfered or radiused inlet was developed by programming. The model was verified against the results of commercial computational fluid dynamics codes. It turns out that the model has high precision, excellent convergence, and can predict the flow parameters under working conditions of low Reynolds number, supersonic and high pressure ratio with an acceptable error. And only geometric features, rotational speed and boundary conditions are required for one-dimensional modeling. Thus, it can be applied in the one-dimensional calculation and design of secondary air system widely.

Published: October 2013

In this study, a Computational Fluid Dynamic (CFD) model is established to obtain the 3-D flow characteristic, temperature distribution of the pressurized water reactor (PWR) upper plenum and hot-legs. In the CFD model, the flow domain includes the upper plenum, the 61 control rod guide tubes, the 40 support columns, the three hot-legs. The inlet boundary located at the exit of the reactor core and the outlet boundary is set at the hot-leg pipes several meters away from upper plenum. The temperature and flow distribution at the inlet boundary are given by sub-channel codes. The computational mesh used in the present work is polyhedron element and a mesh sensitivity study is performed. The RANS equations for incompressible flow is solved with a Realizable k-ε turbulence model using the commercial CFD code STAR-CCM+. The analysis results show that the flow field of the upper plenum is very complex and the temperature distribution at inlet boundary have significant impact to the coolant mixing in the upper plenum as well as the hot-legs. The detailed coolant mixing patterns are important references to design the reactor core fuel management and the internal structure in upper plenum.

Published: October 2013

The upward gas-liquid cross flow around a square cylinder was simulated using two fluid model with the multi-scale turbulent model based on the variable interval time average method. The computational results show that the multi-scale turbulent model can successfully simulate lift coefficient, drag coefficient and vortex shedding characteristics of flow around a body, and can also accurately predict the void fraction distribution and flow structure. Compared with the experimental data, the results of the multi-scale model are better than that of Standard k-ε model and RNG k-ε model. Hence, the study of this paper certificates further that this model can be used in the simulation of the gas-liquid flow around bluff bodies and outher engineering application.

A Robust and Practical Multi-Moment Finite Volume Model for Computational Fluid Dynamics
Authors: Xiao Feng , Xie Bin
Published: October 2013

A robust and practical CFD code has been developed. The numerical framework, so-called VSIAM3 (Volume/Surface Integrated Average based Multi-Moment Method) makes use of two kinds of integrated moments of physical field, i.e. the volume integrated average (VIA) and the surface integrated average (SIA), which are treated as the computational variables and separately updated in time. VSIAM3 formulation is essentially different from conventional finite volume method and provides a convenient and robust framework to accommodate many existing numerical techniques for simulating various complex flows. In this paper, we will present the underlying idea of VSIAM3 and the extensions to make it applicable to various practical problems. Efforts toward high computational performance on hard wares with distributed memory and GPGPU will be also reported.

Authors: Tan Jia Bo
Published: October 2013

To preserve the symplecticity property, it is natural to require numerical integration of Hamiltonian systems to be symplectic. As a famous numerical integration, it is known that the 2-stage RadauIA method is not symplectic. With the help of symplectic conditions of Runge-Kutta method and partitioned Runge-Kutta method, a symplectic partitioned Runge-Kutta method and a symplectic Runge-Kutta method are constructed on the basis of 2-stage RadauIA method in this paper.
Calculation of Fourth-Order Tensor Product Expansion by Power Method and Comparison of it with Higher-Order Singular Value Decomposition
Authors: Ishida Akio , Noda Takumi , Murakami Jun , Yamamoto Naoki , Okuma Chiharu
Published: October 2013

Higher-order singular value decomposition (HOSVD) is known as an effective technique to reduce the dimension of multidimensional data. We have proposed a method to perform third-order tensor product expansion (3OTPE) by using the power method for the same purpose as HOSVD, and showed that our method had a better accuracy property than HOSVD, and furthermore, required fewer computation time than that. Since our method could not be applied to the tensors of fourth-order (or more) in spite of having those useful properties, we extend our algorithm of 3OTPE calculation to forth-order tensors in this paper. The results of newly developed method are compared to those obtained by HOSVD. We show that the results follow the same trend as the case of 3OTPE.
A Blind Watermarking Method Based on Space Reconstruction
Authors: Tan Xiu Hu
Published: October 2013

Watermarking embeds information into a digital signal like audio, image, or video. Reversible image watermarking can restore the original image without any distortion after the hidden data is extracted. In this paper, we propose a blind watermarking method based on space reconstruction. Through calculating the statistical property of the digital image, we are able to separately obtain the feature spaces. Passing spaces decomposing and reconstructing of the feature spaces, constructing the embedding matrix, we obtain that the robustness of the approach lies in hiding a watermark in the subspace that is the least susceptible to potential modification; and realize the optimization statistics of the embedding watermark. Through analysis and constraint the conditions of subspace, the algorithm we proposed can obtain a high detection probability and security, a low false alarm probability. The robustness of the watermarking method is demonstrated by a kind of attacks through computer simulation.

Authors: Chen Peng Jie , Wang Dong Dong
Published: October 2013

Convex meshfree approximation with non-negative shape functions yields strict positive mass matrix and is particularly favorable for dynamic analysis. In this work, a kernel-enriched quadratic convex meshfree formulation with adjustable local approximation feature is presented. This formulation is built upon the generalized meshfree approximation with a relaxed quadratic reproducing condition. The resulting shape functions of the kernel-enriched quadratic convex meshfree formulation are presented in detail. The convergence behaviors for both static and vibration problems are discussed. Numerical results show that better accuracy can be achieved with the present formulation.
