Analyser le marché du travail par les trajectoires individuelles
Authors: Bruno Anne-Sophie
Published: January 2014

Héritiers de la « mosaïque » multiculturelle mise en place à l’époque coloniale, les migrants de Tunisie installés en région parisienne après les années 1950 constituent un laboratoire hors du commun pour étudier les phénomènes de discrimination au travail. Le recours à des données appariées croisant l’étude des trajectoires salariées avec les caractéristiques des entreprises qui les emploient permet de porter un regard nouveau sur les mécanismes de mobilité sociale et les inégalités. L’étude met au jour l’importance des discriminations dont les étrangers sont l’objet sur un marché du travail segmenté, révélant l’étendue des formes de travail précaire au cœur des Trente Glorieuses, loin de l’image d’un âge d’or du salariat stable et bien rémunéré.
La Corse, ses morts et la guerre de 1914-1918
Authors: Rey Didier
Published: January 2014

Longtemps soumis à des interprétations historiques marquées du sceau de différents nationalismes (français, italien et corse), le bilan chiffré de la Grande Guerre en Corse continue d’être sujet à polémiques. Le présent article s’intéresse à la construction et aux enjeux de ces discours multiples ainsi qu’à leurs conséquences sur la représentation que les insulaires se font d’eux-mêmes. Partie prenante de la construction de l’identité française de la Corse et repoussoir des prétentions italiennes de l’entre-deux-guerres, la surévaluation du nombre de victimes se retourne, dans les années 1980, contre ses promoteurs au point d’être instrumentalisée par le nationalisme corse. Dès lors, une querelle des chiffres va perdurer jusqu’à nos jours.

Magnetic Levitation and Rotation for Feasibility of Free-Form Machining
Authors: Shih Alexander H. , Liang Steven Y.
Published: January 2014

This paper presents a new transformative manufacturing methodology for free-form machining. An experimental prototype machine is constructed to levitate and rotate an object attached with sharp edges, which act as a cutter for the purpose of performing machining processes. This device aims to lead to a technological breakthrough, overcoming the limitation of the workpiece features, and achieve greater free-form machining capability. The construction of curved holes and interior surfaces are constrained by the geometry of the machine tool. The proposed concept creates a new device that uses a magnetic field generator as a base. It is loaded with a constant power imposing a vertical physical force to balance gravity and stabilize the cutting tool. With the uniqueness of a preferred orientation between the tool and the base, a rotating surface placed below the base permits the rotation of the cutting tool in order to achieve desired tool rotation speed. A smooth and controlled cut is achieved on a soft material. The result shows the feasibility of the device to achieve similar outcomes as a machine tool.

Published: January 2014

The layer-by-layer deposition technique was adopted in this paper to improve the physical strength properties of alkaline peroxide mechanical pulp (APMP). The cationic starch (CS), anionic polyacryamide (APAM) and cationic polyacryamide (CPAM) were chosen and used to build-up polyelectrolyte multilayers on surface of APMP fibers. The improvements of physical strength of pulp through adsorption of different polyelectrolyte onto fibers were discussed and compared. The results showed that when the APMP fibers were treated with CPAM, the breaking length and burst index were 53% and 83% respectively, higher than that of untreated pulp. The optimal treatment conditions are 60 mgCPAM/g pulp, 1.5% pulp concentration and 9min treatment time. The pulp deposited by CPAM-APAM polyelectrolyte multilayer gave a highest physical strength compared with pulp with other multilayer deposition such as CS-APAM. At the whole beating degree range investigated in this paper, the CPAM-APAM deposition on fiber surface can improve the physical strength properties significantly, especially when the beating degree is at 40oSR.

Authors: Wang Cheng
Published: January 2014

This study introduces a modified bidimensional empirical mode decomposition method to deal with high resolution images. To avoid solving large linear equations and calculating large matrix, the images are split into several blocks, processed individually, and subsequently joined into one. Thus, the complexity of time and space is lowered efficiently.

The Improvement and Evaluation of an Analog Digital Television System’s Availability and Users Experience
Authors: Li Zhuo Jia , Yang Cheng , Wu Xiao Yu
Published: January 2014

Based on the RGBD sensor, this passage suggested a method named ‘Control-right Management’ to reduce the Interaction Information in order to bring better communication efficiency of an Analog Digital Television System. This system was base on fingertip, dynamic and static hand gesture recognition,and it can be controlled by person in the mid-air. And then split and recombination of different operation elements as “Complex Group Gesture” to improve the system’s availability and users experience. According to the Goals Operators Methods Selection Rules(GOMS) model we analyzed the operation step by step and found the redundant process, then reduce the operation time and steps to give the users better availability and users experience. Calculated by the formula of interaction efficiency, the changed operation showed more efficient than before.Finally we take some experiments of our methods and propose several specialize quantitative evaluation methods that can be used in the field of Digital Television System.

Without the railway material supplies, the rail traffic construction cannot make rapid development. Online material procurement bidding saves more time and cost for the personnel than on the site ever before. This paper introduces the interactive consultation based on MooTools long polling technology.
Research on Workflow Management Model Based on Ontology in Data Center
Authors: Chen Gang
Published: January 2014

Workflow is a kind of automatic execution of business process partly or fully, according to a series of rules, documents, information or tasks which can be transferred and executed in different executor such in Data center. Modeling process workflow management model on ontology is divided into following steps based on: Determine professional field and category of Ontology; Important terms and concepts; Definition of class and class hierarchy; Define class attributes and surface properties, Because user demand always changes according to the development of economic, In workflow management system, user demand migration prediction system can give some help. There are two subsystems: Data Mining subsystem and migration of recommendation subsystem.
Automatic Target Segmentation and Tracking in Intelligent Video Surveillance
Authors: Yang De He , Zhang Yi , Wang Ya Ping
Published: January 2014

According to complex environmental identification for the problem of multitarget mobile and stationary state in a fixed scene, this paper provides a technology framework for the forthcoming coexisting multiple target detection and tracking, extracts video frame background map using the mean of multiple video sequences, makes edge detection of the background picture, judges the static target using positive and negative samples of the background image, and uses the Gaussian distribution of background difference to realize the extraction of foreground image. We utilizes the comprehension of non parametric statistical model and color model to eliminate the shadow of foreground image.After eliminating the shadow of the foreground image,we uses Mean Shift dynamic target tracking method to track the interesting objects. Experimental results show that it has strong robustness and stability for the influence of light slow change, occlusion and motion state.
