Les conséquences de la décentralisation sur la gestion du RMI
Authors: Avenel Cyprien
Published: November 2013

La loi du 18 décembre 2003 a décentralisé le revenu minimum d’insertion. Depuis, les conseils généraux ont en charge le pilotage intégral du dispositif. Cette décentralisation a un impact sur les caisses d’Allocations familiales (CAF) qui ont continué à assurer la gestion et la liquidation de la prestation. Plus d’un an et demi après la décentralisation, une enquête a été réalisée auprès des CAF. Cet article fait le point et analyse les modifications engendrées par la loi. L’auteur passe en revue l’intégralité du dispositif, de son instruction à sa gestion en passant par la nécessaire collaboration qui s’instaure dorénavant entre les conseils généraux et les CAF. De nouvelles relations se sont nouées entre les deux institutions. Le terme « partenariat » est aujourd’hui le maître mot de ces relations. Cependant, l’enjeu de cette décentralisation est de définir ou, plutôt, de redéfinir ce partenariat, son contenu et ses réalités tant techniques que politiques.
La PAJE améliore-t-elle le choix des parents pour un mode de garde ?
Authors: Marical François , Minonzio Jérôme , Nicolas Muriel
Published: November 2013

Les bénéficiaires de la prestation d’accueil du jeune enfant (PAJE) présentent des profils très divers selon le complément dont ils bénéficient. Étant donné leur situation vis-à-vis de l’emploi et leur niveau de ressources, le choix d’un mode de garde ou celui de s’arrêter de travailler rencontre de multiples contraintes, budgétaires, organisationnelles ou liées à l’offre d’accueil. Grâce au bénéfice de la PAJE, la contrainte financière en jeu au moment du choix se trouve atténuée, voire supprimée. En ce sens, la PAJE permet le libre choix pour un certain nombre de ses bénéficiaires, en particulier ceux pour lesquels sont versés le complément de libre choix d’activité à taux plein et le complément de mode de garde à domicile. Dans d’autres cas, la prestation améliore le choix de la garde, même si la solvabilisation apportée ne suffit pas à effectuer un choix idéal.
Réduire son activité pour garder son enfant : les effets de la PAJE
Authors: Marical François
Published: November 2013

Les parents peuvent bénéficier d’une allocation pour garder eux-mêmes leurs enfants en contrepartie d’une réduction partielle ou totale de leur activité. La mise en place de la prestation d’accueil du jeune enfant (PAJE) pour les enfants nés après le 1er janvier 2004 a modifié l’ensemble des aides à la garde. En particulier les montants des prestations ont été substantiellement augmentés et les familles de un enfant se sont vu offrir la possibilité de limiter leur activité. La mise en place de ce dernier dispositif connaît un vif succès : début 2006, 14 % des familles comptant un seul enfant âgé de cinq mois avaient recours à une cessation totale d’activité et 6 % à une cessation partielle d’activité pour un des parents. Le recours à un arrêt partiel a augmenté en raison de la PAJE pour les familles de deux enfants, particulièrement au sein des familles les plus aisées. Le recours à un arrêt total d’activité est resté relativement stable, mais une analyse plus fine montre un déclin du recours au sein des familles les moins aisées, ces familles se tournant vers d’autres modes de gardes rendus eux aussi plus attractifs. Par ailleurs, la mise en place de la PAJE a diminué les contraintes de choix des familles.
Les désordres conjugaux comme risque pour l’enfant [Adultère, maternité et paternité dans les procédures de divorce]
Authors: Nagy Véronika
Published: November 2013

Marital disruptions as a risk for the child. Adultery, maternity and paternity in divorce proceedings.

Can there be any relationship between marital infidelity, which appears to be an amorous and/ or sexual disruption perceived as a personal matter between the two members in a couple, and the issue of their children’s well-being ? Since the reform dated 11 July 1975 French family law has clearly stated that this is not the case ; they decide on the fate of under-aged children in a separating couple, the divorce judge must be guided only by the child’s interest and is therefore required to overlook everything affecting the relationship between the adults. However, a review of 47 divorce cases involving a fault claim indicates that the divorcing parents present the partner’s infidelity as a threat to the children’s well-being, using differentiated male and female representations. Such results raise the question of the distinction between ‘ marital couple’ and ‘ parental couple’ whilst casting a whole new light on the issue of contemporary re-compositions of male and female representations.
Inflexions des trajectoires professionnelles des hommes et des femmes après la naissance d’enfants

Career changes for men and women after childbirth.

Although it seems clear that childbirth does not affect the careers of men and women symmetrically, quantitative data measuring such effects are few and far between. One of the objectives of the Families and Employers survey conducted by INED and INSEE in 2004-2005 is to assess the impact of childbirth on the career of both parents. To do so, the survey combines statements about careers in the year following childbirth and a calendar of professional and family activities. For men, childbirth may on occasion lead to a modification in professional activity, but such changes concern a position or job change or an increase in activity or responsibility. The advent of a child more often leads to career interruptions for women. The effect is amplified with successive births. Changes are quite varied after the first birth : resignation or exit of activity ; full-time parental leave ; change in jobs, parttime and unemployment. After a second or third birth, a greater proportion of women take parental leave or part-time work. The divide between men and women widens as the number of births rises.
Comparaison du soutien financier apporté aux familles dans douze pays européens
Authors: Math Antoine , Meilland Christèle
Published: November 2013

Cet article compare le niveau et les modalités du soutien financier des familles au moyen de la méthode des ménages ou cas types dans douze pays européens de niveau de développement comparable : cinq pays nordiques (Danemark, Finlande, Suède, Islande et Norvège), deux pays insulaires (Irlande et Royaume-Uni) et cinq pays d’Europe continentale (Allemagne, Autriche, Belgique, France, Pays-Bas). L’article étudie le rôle joué par les différentes mesures, en particulier les transferts sociaux et les prélèvements, et les éventuelles variations selon la configuration familiale et le niveau de revenu. Les principales mesures participant au soutien financier des familles s’avèrent être les prestations familiales, les aides au logement et, à l’exclusion des pays nordiques et de l’Irlande, l’impôt sur le revenu. Le poids respectif de ces mesures dans le total de l’aide varie d’un pays à l’autre et au sein de chaque pays en fonction du niveau de revenu mais assez peu du nombre d’enfants. Enfin, la méthode permet d’examiner certaines dimensions redistributives ou formes de ciblage, telle que l’évolution de l’aide en fonction du nombre d’enfants ou en fonction du niveau de revenu.
L’assistance, un mode paradoxal d’acquittement de la dette collective
Authors: Bec Colette
Published: November 2013

Assistance has been severely criticised throughout its secular history. Assistance is accused of contributing to what it is supposed to fight and is blamed for many social ills and considered the vector of many policy dangers. At a time when

criticism is at its most virulent, political use of assistance reaches its height. The purpose of this article is to explain this paradox based on an analysis of three historically and politically significant moments.
Le chômage comme déterminant de l’évolution du nombre d’allocataires du RMI
Authors: Donné Stéphane , Cazain Sophie
Published: November 2013

The purpose of this article is two-fold : trace trends in the number of recipients receiving revenu minimum d’insertion (RMI) benefits and try to explain them in terms of variations in the number of persons unemployed. The relationship between RMI and unemployment was ascertained using an econometric equation which made it possible to note that only a sufficiently large reduction over a long period could lead to diminution in the number of RMI recipients. The relationship between unemployment and RMI benefits may be modified over the short term given the implementation of new bonus measures after October 2006 and, over the longer term, with the implementation of the revenu de solidarité active (RSA).
Trois ans après la décentralisation du RMI [Une analyse du rôle des caisses d’Allocations familiales]
Authors: Avenel Cyprien
Published: November 2013

This article measures and assesses the main trends in effect in managing the Revenu Minimum d’Insertion (RMI) by the caisses d’Allocations familiales (CAF) since the measure was decentralised. In comparison with a preliminary survey in 2005 during the implement operation phase, the author analyses the developments in the role and position of CAF in managing RMI benefits withthe delegation system was introduced and the impact of decentralisation on organisation. The role of CAF has increased and a new cooperation relations with département authorities came into, resulting in particular in a heightened checking policy and an increase in requests for statistical data. Although CAF continue to perceive their partnership relationship with départements positively and, indeed, the decentralised RMI, they also note that their role as experts in the benefit and players in the policy has grown.
Conciliation des vies familiale, professionnelle et sociale des allocataires de minima sociaux
Authors: Nicolas Muriel , Tomasini Magda
Published: November 2013

L’objectif de cet article est de montrer dans quelle mesure et en quels termes les questions de conciliation vie familiale et vie professionnelle se posent aux allocataires de minima sociaux. Il y est précisément question des bénéficiaires du revenu minimum d’insertion, de l’allocation de parent isolé et de l’allocation de solidarité spécifique. Si le besoin d’aide à la garde d’enfant est réel, les prestations légales ne semblent pas adaptées à un public bien particulier en raison de sa situation financière extrêmement contrainte et de son éloignement du marché du travail. L’entourage peut contribuer à faciliter la conciliation, mais cela se produit surtout lorsque la personne est proche du marché du travail. Elle pourra alors compter surtout sur son entourage familial pour trouver une aide permettant de surmonter les difficultés de conciliation vies familiale et professionnelle.
Flowering phenology and its implications for management of big‐leaf mahogany Swietenia macrophylla in Brazilian Amazonia
Authors: Grogan James , Loveless Marilyn D.
Published: November 2013

• Premise of the study: Flowering phenology is a crucial determinant of reproductive success and offspring genetic diversity in plants. We measure the flowering phenology of big‐leaf mahogany (Swietenia macrophylla, Meliaceae), a widely distributed neotropical tree, and explore how disturbance from logging impacts its reproductive biology.

• Methods: We use a crown scoring system to estimate the timing and duration of population‐level flowering at three forest sites in the Brazilian Amazon over a five‐year period. We combine this information with data on population structure and spatial distribution to consider the implications of logging for population flowering patterns and reproductive success.

• Key results: Mahogany trees as small as 14 cm diam flowered, but only trees > 30 cm diam flowered annually or supra‐annually. Mean observed flowering periods by focal trees ranged from 18–34 d, and trees flowered sequentially during 3–4 mo beginning in the dry season. Focal trees demonstrated significant interannual correlation in flowering order. Estimated population‐level flowering schedules resembled that of the focal trees, with temporal isolation between early and late flowering trees. At the principal study site, conventional logging practices eliminated 87% of mahogany trees > 30 cm diam and an estimated 94% of annual pre‐logging floral effort.

• Conclusions: Consistent interannual patterns of sequential flowering among trees create incompletely isolated subpopulations, constraining pollen flow. After harvests, surviving subcommercial trees will have fewer, more distant, and smaller potential partners, with probable consequences for post‐logging regeneration. These results have important implications for the sustainability of harvesting systems for tropical timber species.
Ellipsometry and XPS comparative studies of thermal and plasma enhanced atomic layer deposited Al2O3-films
Authors: Haeberle Jörg , Henkel Karsten , Gargouri Hassan , Naumann Franziska , Gruska Bernd , Arens Michael , Tallarida Massimo , Schmeißer Dieter
Published: November 2013

We report on results on the preparation of thin (<100 nm) aluminum oxide (Al2O3) films on silicon substrates using thermal atomic layer deposition (T-ALD) and plasma enhanced atomic layer deposition (PE-ALD) in the SENTECH SI ALD LL system. The T-ALD Al2O3 layers were deposited at 200 °C, for the PE-ALD films we varied the substrate temperature range between room temperature (rt) and 200 °C. We show data from spectroscopic ellipsometry (thickness, refractive index, growth rate) over 4” wafers and correlate them to X-ray photoelectron spectroscopy (XPS) results. The 200 °C T-ALD and PE-ALD processes yield films with similar refractive indices and with oxygen to aluminum elemental ratios very close to the stoichiometric value of 1.5. However, in both also fragments of the precursor are integrated into the film. The PE-ALD films show an increased growth rate and lower carbon contaminations. Reducing the deposition temperature down to rt leads to a higher content of carbon and CH-species. We also find a decrease of the refractive index and of the oxygen to aluminum elemental ratio as well as an increase of the growth rate whereas the homogeneity of the film growth is not influenced significantly. Initial state energy shifts in all PE-ALD samples are observed which we attribute to a net negative charge within the films.

Authors: Bonaccorsi Paola , Gioia Maria Luisa Di , Leggio Antonella , Minuti Lucio , Papalia Teresa , Siciliano Carlo , Temperini Andrea , Barattucci Anna
Published: November 2013

A new class of molecules with a triptycene rigid core surrounded by six monosaccharide residues was synthesized. Hexakis(bromomethyl) substituted triptycene was converted into a six-armed triptycene azide (2,3,6,7,14,15-hexakis(azidomethyl)-9,10-dihydro-9,10-[1’,2’]benzenoanthracene). The key step of the synthesis was the cycloaddition of the azide to 2-propyn-1-yl β-D-gluco- or galactopyranosides. All products were isolated in good yields and were fully characterized.

De l'initiative à l'expérimentation : la longue vie du soutien à l'innovation
Authors: Cros Françoise
Published: November 2013

Depuis les années 1960, la mise en place de dispositifs nationaux d’aide au développement des innovations scolaires a posé fondamentalement la question de la représentation politique du processus de réforme du système éducatif. Plusieurs dispositifs ont été installés par des textes législatifs et des déclinaisons locales. À l’occasion de la demande d’évaluation du dispositif issu de la loi de 2005, plus précisément l’article 34, par le Haut Conseil à l’Évaluation, cette contribution interroge les dispositifs antérieurs et leurs effets ou contre-effets au regard du développement de ce dispositif et sur son évaluation.
La musique dans le Dictionnaire de pédagogie et d'instruction primaire de Ferdinand Buisson : une discipline scolaire pour moraliser et éduquer le peuple
Authors: Grivet Bonzon Catherine
Published: November 2013

Texte majeur et fondateur, le Dictionnaire de Pédagogie et d’instruction primaire de Ferdinand Buisson (deux éditions : 1887 et 1911) est une œuvre dont nous proposons une lecture des articles liés au chant et à la musique comme objets d’enseignement. Nous tenterons de comprendre à travers les articles consacrés à l’édification d’une discipline scolaire singulière, quelques-unes des enjeux, des luttes et des rapprochements inhérents aux changements et aux bouillonnements de la fin d’un siècle, celui de l’invention de l’École Républicaine. Au-delà des dissensions et dans leur volonté d’insérer la musique dans la nouvelle culture scolaire primaire tant pour socialiser que pour émanciper le futur citoyen, les différents auteurs ouvrent la voie déjà pressentie par Schiller de la contribution essentielle des pratiques artistiques dans la construction du sujet, dans son épanouissement autant que dans ses rapports sociaux.
Maternités adolescentes : le temps bousculé
Authors: Sellenet Catherine , Portier-Le Cocq Fabienne
Published: November 2013

L’objectif de cet article est d’analyser le processus de parentalisation de la maternité adolescente. En s’appuyant sur des données quantitatives (23 questionnaires) et qualitatives (29 entretiens), recueillies auprès de jeunes mineures enceintes ou mères, les auteurs analysent leur rapport au temps, au corps, ainsi que les métamorphoses identitaires enclenchées par l’annonce de cette naissance qui vient bousculer le temps de l’adolescence. Cette étude met à jour les fragilités sociales de ces jeunes, mais, plus encore, montre que l’identité maternelle doit se construire par opposition aux représentations et injonctions d’une société hostile aux maternités précoces. L’identité maternelle est conquise contre des rôles assignés (celui d’adolescente), contre des étapes temporelles scandées. La présente recherche questionne l’accueil fait à ces jeunes mères, l’impact des discours de l’échec (échec de la contraception, ignorance des effets de la sexualité, non maîtrise de la grossesse et du projet d’enfant, risques majorés...) sur la construction de la parentalité.
Perception mutuelle des relations entre les jeunes adultes et leurs parents : distance, appui et conflit
Authors: Mendonça Marina , Fontaine Anne Marie
Published: November 2013

Le premier objectif de cette étude est d’évaluer la variation de la différenciation familiale et de la qualité des relations parent-enfants (appui intergénérationnel, satisfaction et conflit) en fonction du degré de concrétisation de certaines transitions développementales de jeunes adultes (indépendance économique et résidentielle par rapport aux parents). Le deuxième objectif est de comparer les points de vue des parents et des enfants face aux mêmes dimensions, en considérant l’effet modérateur du genre. L’échantillon est formé de 115 triades (jeune-adulte, mère et père). Les résultats indiquent que les transitions développementales n’influencent que faiblement la perception des relations parents-enfants qui est toutefois clairement déterminée par le genre des partenaires. En outre, les parents présentent une perception plus positive des interactions avec leurs enfants que ces derniers, mais les transitions développementales des jeunes adultes favorisent la convergence de perspectives entre générations.
Parents et grands-parents face à la garde du jeune enfant en France et en Pologne
Authors: Pawłowska Aleksandra
Published: November 2013

L’objectif de cet écrit est de comprendre ce qui se joue dans la dynamique des relations intergénérationnelles lorsqu’il est fait appel aux grands-parents pour garder les petits-enfants en France et en Pologne. Les pratiques de garde dans les deux pays sont analysées à travers trois générations, au moyen d’un entretien compréhensif mené auprès de 37 lignées de parents et de grands-parents. L’examen des discours bigénérationnels fait ressortir des différences de recours aux grands-parents. Plus précisément, en Pologne, où les politiques sociales sont faibles, la famille élargie joue un rôle très important dans la garde des plus jeunes, puisque les grands-parents constituent souvent le mode de garde principal. Le contrepoids français est le recours ponctuel aux grands-parents, mais à l’instar des familles polonaises, indispensable dans la promotion professionnelle des jeunes générations.
Stratégies éducatives parentales et mécanismes familiaux de réussite des enfants bamilékés fosterés en France
Authors: Kamga Monique
Published: November 2013

Le présent article apporte un éclairage sur les processus éducatifs intrafamiliaux favorisant, parmi d’autres, la réussite scolaire des enfants bamilékés (Cameroun) accueillis dans le cadre du fosterage, par des membres de leur parenté installés en France. L’étude porte sur la transposition de cette pratique traditionnelle et informelle dans un environnement socio-culturel où la mobilité des enfants est formalisée et règlementée et interroge l’impact de la migration sur l’évolution de la nature des liens parents/enfants ainsi créés. À partir de 30 entretiens semi-directifs auprès des protagonistes bamilékés du fosterage en France, cet article se centre sur les stratégies éducatives des parents qui associent leurs références culturelles informelles aux méthodes et valeurs socio-éducatives françaises. Les résultats montrent comment ces parents parviennent à stimuler les capacités et les performances de l’enfant fosteré afin de l’amener à la réussite scolaire dans un cadre familial « impromptu », loin des parents biologiques.
La paternité en contexte de violence conjugale

Published: November 2013

Cet article présente les résultats d’une étude qualitative menée auprès de vingt-deux pères participant à une thérapie de groupe pour violence conjugale. Cette étude avait pour but de comprendre les expériences paternelles de ces hommes et les éléments qui influencent leur paternité. Dans le cadre des entrevues individuelles semi-dirigées, les pères ont été très éloquents quant aux effets de leur violence sur leur paternité, mais ils ont aussi parlé des divers changements qu’ils ont réalisés, sur le plan de leurs comportements et attitudes depuis qu’ils ont entamé leur démarche d’aide. Les résultats de l’étude révèlent qu’il y a des raisons d’être concerné par rapport aux pratiques paternelles de ces hommes. Les résultats font également apparaître l’importance d’adopter une analyse dynamique et évolutive de la paternité des hommes reconnaissant ainsi qu’ils sont en processus de changement.

In this presented model, the concept of one step state transition matrix in minimal time difference tt+t is given for the repairable systems, and common cause failure, the general continuous distributions for working times and repair times are all took account. Finally, the estimation methods of the correlation scalar parameter and selection criterion for copulas are also given.
A Fault Tolerant Integrated Navigation Scheme Realized through Online Tuning of Weighting Factors for Federated Kalman Filter
Authors: Ushaq Muhammad , Cheng Fang Jian
Published: November 2013

Strapdown Inertial navigation (SINS) is a highly reliable navigation system for short term applications. SINS functions continuously, less hardware failures, renders high speed navigation solutions ranging from 50 Hz to 1000 Hz and exhibits low short-term errors. It provides efficient attitude, angular rate, acceleration, velocity and position solutions. But, the accuracy of SINS solution vitiates with time as the sensor (gyros & accelerometers) errors are integrated through the navigation equations. Average navigation grade SINS are capable of providing effective stand-alone navigation for shorter duration (few minutes) applications Stand-alone SINS capable of providing solutions for applications exceeding 10 minutes duration, are generally highly expensive ($0.1M to $2.0M). To cope with this limitation, a cost effective solution is the integrated navigation system wherein the unboundedly growing errors of SINS are contained with the help of external non-inertial navigation aids like GPS, Celestial Navigation System (CNS), Odometer, Doppler radars etc. The efficient methodology for integrated or multi-sensory navigation is the Federated Kalman Filter (FKF) scheme. In FKF architecture, a reference SINS solution is integrated independently with each of the aiding navigation systems in a bank of local Kalman filters. There are a number of different ways in which the local filter outputs may be combined to produce an integrated navigation solution. The no-reset, fusion-reset, zero-reset, and cascaded versions of federated integration have been used by different researcher and navigators over the years. All different schemes of FKF have certain pros and cons. Fusion-reset method although nearly optimal is less fault tolerant while no-resent scheme renders highly fault tolerant solutions but with sub-optimal solutions and compromised precision. To enhance the fault tolerance ability of fusion-reset scheme of FKF, additional parameters called weighting factors are introduced to tune the contribution of each local filter in the final data fusion. The presented scheme has been found nearly optimal and expressively fault tolerant.
A Design and Application of Security-Monitoring System for Tiny Relics
Authors: Zhou Ying , Yao Yan , Wu Mei
Published: November 2013

In this paper, a security-monitoring system for tiny relics is proposed, which is used to improve the reliability and stability of the museum security system nowadays. This paper analyzed the security-monitoring system of most of the museums in China, and two defects have been discovered. One is that there is almost no security facility which can provide special protection for tiny relics. The other is that there is no effective way to retrieve rare and valuable relics missing in the museum. The security-monitoring system for tiny relics can make up for these weaknesses by integrating two modules, alarm module and position module. Using reed switch as sensitive element, added with chip PT2262, the alarm module can sense micro movement and send position code to central computer wirelessly. Meanwhile, adopting radio frequency identification (RFID) technology for indoor location, position module can provide precise track of moving objects in museums. Combined with traditional security-monitoring, this system can achieve the best protection for tiny relics.
Bond Behavior of Standard and Reinforced Anchorage between CFRP Sheet and Natural Calcareous Stone
Authors: Anania Laura , Badalà Antonio , D’Agata Giuseppe
Published: November 2013

In the past two decades, CFRP had been used to strengthen and repair r.c. structures and recently it is also employed to strengthen historical or monumental buildings constituted by masonry structure. However, premature failure due to debonding of the FRP is one of the important issues still to be resolved. Numerous word wide research studies have dealt with the debonding problem in r.c. structures but only a few works were carried out in the masonry structures area. So, the study of the global behaviour of the reinforced masonry element seems to be very useful, both for a congruous design and to verify the strengthening strategy. To this aim, this paper summarizes the debonding phenomena between C-FRP strip and natural calcareous rock brick, employed in our buildings, by means of a testing investigation. Two different kinds of anchorage were designed and employed for the tested samples: standard and reinforced anchorage. The experimental tests carried out on the specimens permits us to compare the effective bond length, with the one obtained by International rules and especially with the Italian CNR-DT200/2004 formulation and to say that the effective bond length dictates by the rules undervalues the experimental data. The data obtained permit us also to know the shear-slip delamination curve useful for the numerical investigation, as well as both the failure mode and the "II mode" fracture energy.

Authors: Ma Shu Yuan , Sameh Bdran , Samo Saifullah , Bary Aymn
Published: November 2013

In this paper, the CVT shifting control system based on vehicle operating conditions is modeled and simulated using MATLAB/SIMULINK. The modeling stage begins with the derivation of required mathematical model to illustrate the CVT shifting control system. Then, Linear Quadratic Gaussian (LQG), Proportional- Integrated-Derivative (PID) and Pole Placement are applied for controlling the shifting speed ratio of the modeled CVT shifting system. Simulation results of shifting controllers are presented in time domain and the results obtained with LQG are compared with the results of PID and Pole placement technique. Finally, the performances of shifting speed ratio controller systems are analyzed in order to choose which control method offers the better performance with respect to the desired speed ratio. According to simulation results, the LQG controller delivers better performance than PID and Pole Placement controller.

The Effect of Pheromone in Ant-Based Hyper-Heuristic
Authors: Zalilah Abd Aziz
Published: November 2013

-Ant algorithms mimic the behavior of the ants where their important behavior is the ability to find the shortest path between food sources and their nest despite being almost blind. In the algorithms, as ants travel, they deposit a chemical substance called pheromone which; together with visibility values is used to make decisions. This paper investigates the effects of pheromone values on solving a routing problem; the capacitated vehicle routing problem (CVRP) In our approach, in order to produce a generalized approach, we developed an ant-based hyper-heuristic where pheromone and visibility values consider a non-domain specific knowledge. In this paper, we propose to provide all visited heuristics with some amount of pheromone. The distribution of pheromone values will be distributed proportioned to the performance done by the ants. This is to encourage the exploration of new edges that might lead to better solutions. We show that our results are better when compared to two other ant algorithm hyper-heuristics in the literature.

Rotary Hammer Forging, a New Manufacturing Process
Authors: Hamdy Muhammad M.
Published: November 2013

Rotary forging process has recently been developed in which the material is deformed partially and incrementally and a deformation zone is developed and swept through the material. Since the upper die in rotary forging is always in contact with the workpiece top surface, and presses continuously the workpiece until it takes the final shape in one stroke (i.e. resembling conventional press forging), it might be more definite to name it as rotary press forging. Rotary press forging produces many defects. The author has invented a process, namely, rotary hammer forging, which reduces these defects. The aims of the present work are to introduce the rotary hammer forging process, to study the effects of the fundamental process parameters, and to find out the advantages of RHF. Special set-ups with a rotary die mounted on a lathe chuck being hammered with a pneumatic piston mounted on the lathe carriage have been used. It has been found that the specimen's geometry and the inclination angle affect the extruded length, the mushrooming effect, the eccentricity, the twisting angle, the buckling and the forming time. The defects of buckling, mushrooming, eccentricity and twisting are less severe in rotary hammer forging than rotary press forging. Hence, rotary hammer forging is more beneficial and superior than rotary press forging.

Authors: Guo Zhen , Chen Xin Wu
Published: November 2013

Contourlet-1.3 transform has better performance in directional information representation than the original contourlet transform due to less artifacts and local frequency characteristics, and has been studied by us in retrieval systems and has been shown it is superior to contourlet ones at retrieval rate. In order to improve the retrieval rate further, a novel contourlet-1.3 transform based texture image retrieval system was proposed in this paper. In the system, sub-bands energy, standard deviation and kurtosis in contourlet domain were cascaded to form feature vectors, and the similarity measure function was Canberra distance. Experimental results show that this contourlet-1.3 transform based image retrieval system has higher retrieval rates about 7% to that of the contourlet transform with absolute mean sub-bands energy and standard deviations features under same system structure.

Authors: Niu Lian Jie , Li Jun Hong , Cui Ning
Published: November 2013

The high performance cement concrete mixture design for pavement was studied through a series of laboratory experiments based on an actual project program. We analyzed the data by principal component analysis and tested the concrete performance of strength, shrink and freeze-resistance. The results of a series of experiments indicated that the dry-shrink rate was reduced obviously by using expanding agent. The flexural elastic modulus increased as the flexural strength increasing. Adding air-entraining agent could improve the air content of the concrete, and as a result, the flexural elastic modulus was reduced and freeze-resistance performance was enhanced greatly.

Published: November 2013

An efficient way to repair the damage of concrete is to enable the concrete adapt to the surrounding environment actively and have self-repair capabilities. In this paper, a type of concrete beam with embedded glass fibers filled with adhesive capable of crack self-repair was investigated. The capacity of self-repair cracks in concrete beams was verified by bending tests, and the influence of the layout of glass fibers on crack self-repair was studied. Test results show that the stiffness of concrete beams increases after crack repair. The glass fibers can be arranged according to the average crack spacing of reinforced concrete beams. In addition, the influence of the levels of crack repair on properties of concrete beams was analyzed with the finite element analysis software ANSYS.

Published: November 2013

A kind of new warm mix additive called SAP was proposed in this paper. The principle is using foam to lower the operating temperature of asphalt mixtures. The mixing and molding temperature of SAP warm mix asphalt mixture were measured by viscosity method and void ratio method, which are almost 20°C lower than that of HMA. Considering the engineering applications and test accuracy, the void ratio method is considered to be the better way to measure the operating temperature of asphalt mixtures.
