Numerical optimization and analysis on vibration characteristics of bicycles based on the novel CA-PSO algorithm
Authors: Zhang Jin , Gao Jiang Hua , Wu Jian Guo 
Published: October 2017

Regarding the published researches on bicycles, they fail to design fatigue characteristics of the bicycle. In addition, dynamics and fatigue characteristics are not further improved by using advanced optimization algorithms. Aiming at these questions, this paper tries to optimize dynamics and fatigue characteristics of the bicycle through combining finite element model with advanced algorithms. The advanced algorithm applies ideas of cellular automation (CA) to Particle Swarm Optimization (PSO), and then a hybrid CA-PSO algorithm is proposed. Moreover, the finite element model is also validated by experimental test. Computational results show that: the maximum stress of bicycles is mainly distributed on the frame, especially on joints of different round pipes at different moments mainly because a dead corner is at the joint, and the dead corner can easily cause stress concentration. Under alternating forces, the stress concentration at joints will cause fatigue damage. Therefore, the service life of this position will be the shortest. As a result, the dynamics and fatigue characteristics of the joint position are taken as the optimized objective. In order to verify the optimized effectiveness of the proposed CA-PSO algorithm in the paper, the widely used PSO algorithm and PSO-GA algorithm are also used to optimize the bicycle. When the traditional PSO algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 11.9 % and 14.3 %. When the PSO-GA algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 20.3 % and 12.9 %. When the proposed CA-PSO algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 27.1 % and 18.6 %. Compared with other two kinds of PSO algorithms, optimized effects of vibration accelerations are very obvious. In addition, the fatigue life of the original structure is 5 years, while the fatigue life of the optimized bicycle is 7 years. Therefore, the fatigue life is improved obviously.

A Correlative Approach to Capture and Quantify Substructures by Means of Image Registration
Authors: Britz D. , Webel J. , Gola J. , Mücklich F. 
Published: October 2017

Abstract
The quantification of microstructures is crucial for the development of new materials as well as for the quality assurance. The progress in material science is accompanied by more and more complex and fine microstructures. With this, the quantification of these microstructures is becoming increasingly challenging. One way to get more information from microstructures is by combining images made with different imaging techniques, like scanning electron microscopy and light optical microscopy. Despite a wide variety of commercial software, these different images can still not be combined without a considerable proportion of manual work. In this work, we present a workflow to combine micrographs of different imaging sources by means of image registration with the open source tool FiJi and describe how to extract and analyse single grains concerning their substructure with Matlab© on the example of a martensitic dual phase steel.
Les deux (ou trois) carrières de Richard Hoggart
Authors: Ducournau Claire 
Published: October 2017

Analysant d’abord les hommages posthumes différenciés rendus à Richard Hoggart de part et d’autre de la Manche à sa mort en 2014, cet article défend l’hypothèse d’une double carrière de cette figure intellectuelle et de ses écrits au Royaume-Uni et en France. Auteur d’un succès de librairie lu au-delà du monde universitaire, fondateur institutionnel des cultural studies à Birmingham, Hoggart est toutefois rapidement vu dans ce domaine comme une référence à dépasser, alors que la traduction, en France, de deux de ses œuvres majeures (The Uses of Literacy et A Local Habitation) l’y transforme en sociologue. L’importation de ces textes dans les sciences sociales françaises a nourri la première critique d’importance, par Jean-Claude Passeron et Claude Grignon, du système conceptuel mis en place par Pierre Bourdieu, que la lecture de Hoggart a d’abord implicitement nourri. Sélectives, les références à ses œuvres dans la sociologie de la culture ou des classes populaires se sont ensuite routinisées. Ces usages se sont toutefois accompagnés d’un héritage plus souterrain qui semble moins dépendant des frontières nationales. Hoggart a en effet été pionnier pour légitimer dans la recherche universitaire une prise de parole autobiographique marquée par la réflexivité. Les formes scientifiques d’un tel geste se sont cependant aussi conformées à des cadres disciplinaires et à des logiques épistémologiques de plus en plus distincts, propres à la sociologie française d’un côté et aux studies de l’autre.
La télécollaboration vue par la communication exolingue – Pour un enrichissement mutuel de deux traditions de recherche
Authors: Cappellini Marco 
Published: October 2017

Dans notre article, nous nous proposons de discuter les relations possibles entre les études sur la télécollaboration et les études sur la communication exolingue, le but étant de montrer comment les recherches dans ces deux domaines peuvent s'enrichir mutuellement. Pour ce faire, l'article sera divisé en deux grandes parties : une première où nous dresserons un bref panorama des études dans les deux domaines et montrerons les articulations conceptuelles possibles ; une deuxième partie où nous montrerons certains points d'un tel enrichissement par un exemple concret, tiré d'une étude d'un télétandem.
Hilbert Transformation and Representation of the ax + b Group
Authors: Dang Pei , Liu Hua , Qian Tao 
Published: October 2017

AbstractIn this paper we study the Hilbert transformations over L2() and L2() fromthe viewpoint of symmetry. For a linear operator over L2() commutative with the ax + b group, we show that the operator is of the form λI+ηH, where I and H are the identity operator and Hilbert transformation, respectively, and λ, η are complex numbers. In the related literature this result was proved by first invoking the boundedness result of the operator using some machinery. In our setting the boundedness is a consequence of the boundedness of the Hilbert transformation. The methodology that we use is the Gelfand–Naimark representation of the ax + b group. Furthermore, we prove a similar result on the unit circle. Although there does not exist a group like the ax + b group on the unit circle, we construct a semigroup that plays the same symmetry role for the Hilbert transformations over the circle L2().

Published: October 2017

Introduction Dual mobility (DM) total hip arthroplasty (THA) may reduce dislocation risk, but might increase the risk of high polyethylene (PE) wear due to double wearing surfaces. Methods 127 patients (97 female) with 129 hips operated with THA after displaced femoral neck fracture FNF between 2005 and 2011, were seen for a cross-sectional clinical follow-up. Acetabular components were Saturne® DM cups with 28mm chrome-cobalt heads in UHMWPE. Cementless cups (n = 73) were hydroxyapatite coated. Radiographs were obtained for analysis of cup placement, 2D polyethylene wear and wear-rate (PolyWare 3D), and further radiological evaluation. Activity measurements included Timed Up and Go test (TUG) and walking distance from Harris Hip Score (HHS). Results At a mean follow-up of 2.83 (1.0-7.7) years the mean wear was 0.82 mm (range 0.17-4.51, SD 0.50), and the wear-rate was 0.37 mm (range 0.06-1.90, SD 0.29). Wear-rate of 0.43 mm/year (SD 0.30) in cementless cups was higher (p = 0.004) than 0.30 mm/year (SD 0.27) in cemented cups. Mean age at time of surgery was 75.1 years (range 30-95). There was no correlation between age at time of surgery and wear (p = 0.56). There was no correlation between cup inclination and wear-rate (p = 0.35). TUG was mean 13.4 seconds (range 4.5-30.1) and correlated with wear rate (p = 0.03). Conclusions At short term follow-up, the mean wear-rate in old and low demand patients was high, correlated to activity, and was above the generally accepted osteolysis threshold (0.1 mm/yr.). Cementless HA-coated cups had higher wear-rate than cemented cups.

La investigación “Estrategias metodológicas para el desarrollo lógico-matemático del niño Carlos José del III nivel del I ciclo de Educación Inicial en el Centro Escolar Santa Rosa, Barrio Santa Rosa ubicado en el distrito VI del municipio de Managua en el I semestre, del año 2014” se realizó bajo el enfoque investigación-acción el cual se constituye de diferentes etapas. Esto nos permitió familiarizarnos, observar, caracterizar, explorar, indagar, diagnosticar, reflexionar y proponer diferentes estrategias que pueden ser incluidos en el sistema educativo para poder dar respuestas a las necesidades del niño. A través del diagnóstico se identificó lo siguiente: el niño presentaba dificultades en el desarrollo lógico- matemático; la docente no muestra interés en las necesidades del niño quien es ignorado y no apoyado en su proceso de enseñanza aprendizaje. Moomaw, (2011), comparte que los niños que aprenden los fundamentos de matemáticas en la etapa preescolar tienen las mejores posibilidades de logros escolares. Esto nos facilitó el planteó de objetivos y estrategias que se aplicaron con el propósito de superar dificultades observadas, desarrollando actividades dirigidas a la seriación, agrupación y clasificación, que ayudaran al niño en el desarrollo de su proceso lógico- matemático. Los resultados fueron notorios y nos sensibilizó más con nuestro trabajo hacia los niños, obtuvimos sentido de comprensión y compromiso al desempeñar un trabajo de calidad con estos individuos en proceso de desarrollo, dándoles un seguimiento adecuado con el estímulo, la comprensión, el sentido de pertenencia, dedicación, preparación y la autoevaluación.

Published: October 2017

El presente estudio permitió evaluar la prevalencia de la Enfermedad de Hansen en el barrio Francisco Rojas del municipio de Tipitapa, departamento de Managua, durante el período de Diciembre 2012 a Febrero 2013. Para cumplir tal objetivo se realizaron visitas domiciliares a los contactos de los pacientes diagnosticados con Enfermedad de Hansen durante los años 2000 al 2012 en el Centro Nacional de Dermatología, denominados éstos como casos guías. Durante estas visitas se realizó una inspección completa de la piel a todos los contactos, surgiendo así pacientes con lesiones sospechosas de la enfermedad, a los cuales se les realizaron baciloscopía y biopsia para confirmar el diagnóstico y clasificar la enfermedad. Partiendo de los 9 casos guías surgieron 6 casos nuevos. La prevalencia de la enfermedad para el año 2012 en el barrio Francisco Rojas fue de 10.85 por 10,000 habitantes, la tasa de detección fue de 13.02 por 10,000 habitantes y la proporción de casos en menores de 15 años fue 16.66 %. Tomando en cuenta estos indicadores se puede concluir que existe un foco activo de lepra en el barrio Francisco Rojas del municipio de Tipitapa, y por sus características epidemiológicas debe considerarse un problema de salud pública. Por lo que se recomienda priorizar el diseño de un programa de atención y vigilancia epidemiológica de la Enfermedad de Hansen para un mejor control en la transmisión de la misma.
