SELF-COMPACTING CONCRETE USE FOR CONSTRUCTION WORK ENVIRONMENT SUSTAINABILITY
Authors: Rwamamara Romuald , Simonsson Peter
Published: September 2012

Many of those working on construction sites are exposed to demanding work loads; construction workers lift and carry heavy materials and work in awkward postures. Occupational injuries and accidents due to poor ergonomics are more common in the construction industry and many times lead to human tragedies, disrupt construction processes and adversely affect the cost, productivity, and the reputation of the construction industry. In Sweden, it is reported that concrete workers have the highest relative work-related musculoskeletal injury frequency. Therefore, the use of ergonomic production methods to prevent this can have a significant human, social and financial impact. Research introduced here presents a case study of comparative analyses of ergonomic situations for concrete workers performing concrete casting processes. Three different ergonomic risk assessment methods were used to assess the physical strain, hand-arm vibration and noise affects risks involved in concrete casting work tasks. The combination of technical and managerial factors results in a system where workers are as efficient and safe as possible during their work tasks, and thus, makes the construction work environment sustainable. The aim of our research is to find practical methods to evaluate and compare two different concrete casting methods from an ergonomic perspective. The focus is on the production of cast-in-place concrete bridge constructions where the traditional concrete casting method is compared with the SCC (Self-Compacting concrete) casting method. To be able to identify work-related musculoskeletal injury risks due to concrete casting work tasks, QEC (Quick Exposure Check for musculoskeletal risks), PLIBEL (Checklist for identification for Ergonomics Hazards) and ErgoSAM (Ergonomic production technology method) methods were used. Ergonomic risks analysis methods QEC, PLIBEL and ErgoSAM have all shown capabilities to evaluate construction work activities and thus determine whether a construction work activity constitutes a musculoskeletal risk to the worker or not before any ergonomic intervention is introduced. As a result the present ergonomic risks emanating from work methods used in the traditional concrete placing can be significantly reduced with the use of self-compacting concrete (SCC) that eliminates awkward work postures, noise and hand arm vibration, thereby reducing if not eliminating musculoskeletal injuries among concrete workers during their concrete casting work tasks.

Traffic safety mainly depends on vehicles, pedestrians and road infrastructure. On highways, the heaviest traffic accidents are associated with crossing of the dividing strips by a vehicle and its collision with side obstacles on the junction or road bridge exit. These accidents often occur, when vehicles, running at a high speed, collide with obstacles, which may cause human injuries. In such cases, the probability of fatalities or heavy injuries to people in a traffic accident is very high. Road traffic infrastructure plays an important part in ensuring traffic safety on urban roads and highways. It includes guardrails, speed bumps, pedestrian safety islands, traffic regulation systems, road information infrastructure, etc. Guardrail (known as civil engineering element and traffic safety element) installation may help to reduce the number of human injuries and fatalities caused by traffic accidents. Guardrails of various types are installed on the roads of Lithuania and Ukraine. Guardrails, consisting of metal posts of the profile Σ and a protective beam of the profile W, i.e. ‘double-wave guardrails’, are among the most commonly used ones. The authors of this paper present the analysis of the deformation state of a double-wave guardrail (describing the strains and stresses of its elements).
Art-Activisme : enjeux de créativité urbaine à Bruxelles
Authors: Jamar David
Published: September 2012

Résumé Depuis le milieu des années 1990 et l’événement constitué par l’occupation de l’Hôtel Central, Bruxelles comme enjeu d’actions collectives apparaît sous des formes inédites. Ce sont des lieux désaffectés, des friches ou des lieux discontinus qui font, avant la constitution d’un quelconque programme politique, l’objet de mises en scène artistiques ou culturelles. Depuis celles-ci, se tisse un milieu culturel d’intervention urbaine au contact des hésitations d’autres milieux urbains plus institutionnalisés. Cette construction s’appuie sur des figures : l’Usager, la Créativité, la Métropole, et se distancie ainsi d’une ville héritée des premières luttes urbaines. Il s’agit de saisir les enjeux contemporains de ces transformations, entre propositions alternatives et animation urbaine.
La fabrication de la ville durable entre conflit et participation : les activistes urbains écologistes en région parisienne
Authors: Reynaud-Desmet Lélia
Published: September 2012

Résumé Les « activismes urbains écologistes » recouvrent, dans l’agglomération parisienne, des formes diverses et variées de mobilisations, mais se recoupent par leur volonté d’une meilleure prise en compte des enjeux environnementaux. Prônant l’idée d’une « ville durable », ils agissent en faveur de la promotion des circulations douces ou pour le développement des espaces naturels en créant des jardins urbains et en revalorisant des friches. En étudiant plus précisément quelques-uns de ces mouvements, nous proposons d’analyser la manière dont ils agissent et les modifications qu’ils entraînent sur leur environnement d’action. Nous pourrons ainsi examiner les réponses institutionnelles apportées à ces propositions en matière d’aménagement urbain, en s’interrogeant sur la possible émergence d’une nouvelle forme de participation et de concertation.

Résumé L’activisme urbain à Montréal s’inscrit dans le sillage historique des luttes urbaines avec l’enjeu du droit à la ville. L’héritage des luttes urbaines s’exprime encore aujourd’hui avec les mobilisations pour le logement mais une diversification des objets de mobilisation se manifeste avec un déplacement vers les questions environnementales, d’espace public et d’art dans la ville. Les pratiques militantes évoluent avec l’institutionnalisation des mouvements sociaux mais aussi l’avènement d’un militantisme plus distancié faisant plus de place au numérique.
Les droits de l'homme au service de la lutte politique. Les avocats dans le conflit nord-irlandais (1970-2000)
Authors: Gheda Paolo
Published: September 2012

Résumé Pendant les années 1970, l’escalade du conflit ethnico-religieux entre les communautés catholique-républicaine et protestante-unioniste a marqué profondément l’Irlande du Nord. Après le Bloody Sunday de Derry en 1972, l’éclatement de la violence civile et l’introduction dans le pays du gouvernement direct ( Direct Rule ) de Londres, associés à des mesures spéciales, véritable législation « de temps de guerre », ont pour conséquence l’emprisonnement de membres de groupes paramilitaires revendiquant un statut de prisonniers politiques. Fortement impliqué dans le bras de fer qui oppose ces prisonniers aux autorités britanniques, le monde du droit se montre particulièrement attentif à leur traitement pénitentiaire et tente de donner à leur action une large couverture internationale, avec des relais dans les institutions humanitaires, religieuses et culturelles. Cet article cherche à préciser le rôle joué par les avocats dans la défense des républicains emprisonnés. Il met l’accent sur les pressions qu’eux-mêmes ont subies dans l’exercice de leur profession et sur les répercussions que ces pressions, aux conséquences parfois dramatiques (assassinats), ont eues sur l’organisation de la justice et de la police en Ulster.

Résumé Cet article propose une étude des stratégies de défense des « terroristes croates », jugés en 1935 pour complicité dans l’attentat de Marseille qui coûta la vie au roi de Yougoslavie et au ministre Louis Barthou. Les mémoires de leur avocat, expulsé du tribunal par décision de justice, permettent une relecture d’un épisode exceptionnel et emblématique. Mettant à jour l’itinéraire militant d’un avocat très atypique, ces sources éclairent la part déterminante des conflits politiques dans la gestion judiciaire de cette affaire. Elle est un révélateur des tensions suscitées par la répression légale du « terrorisme politique » dans l’Europe des années 1930.
Modélisation de l’érosion hydrique des sols sur un bassin versant du sud-ouest de Madagascar, le Fiherenana
Authors: Payet Evelyne , Dumas Pascal , Pennober Gwenaëlle
Published: September 2012

À l’échelle de la planète, 70 % des littoraux sont en position de recul. À l’inverse, sur certains littoraux de la façade ouest de Madagascar, à l’embouchure des fleuves, les processus d’accrétion l’emportent sur les processus de recul. Ainsi, depuis les années 80, le complexe récifal de Tuléar est considéré comme dégradé. Cette dégradation serait principalement induite par l’asphyxie de la structure récifale par les matériaux d’origine terrigène apportés par le fleuve du Fiherenana, qui draine un bassin de 7 700 km². Afin de mettre en lumière les processus d’érosion en cours sur le bassin versant du Fiherenana, une étude basée sur la modélisation de l’érosion hydrique des sols est proposée dans le cadre de cet article. Le modèle USLE (Universal Soil Loss Equation) a été choisi afin de quantifier et de spatialiser les processus d’érosion hydrique à l’échelle du bassin versant. Ces modèles d’ores et déjà mis en œuvre dans différents milieux et à différentes échelles prennent en compte cinq paramètres déterminants dans les processus d’érosion, dont : l’agressivité des précipitations, l’érodibilité des sols, l’inclinaison et la longueur de la pente ainsi que le couvert végétal et les moyens mis en place pour lutter contre l’érosion des sols. Cette étude s’inscrit dans une démarche de Gestion Intégrée de la Zone Côtière. Elle constitue une première approche dans l’identification des processus d’altération des bassins versants de l’Ouest malgache et aide à la compréhension des dynamiques actuelles des bassins versants littoraux.

Authors: He Tong Zhou , Shen Yan Jun
Published: September 2012

The goal of this paper is to look for relatively stable area in the Vehicular Ad hoc Network (VANET), thereby helping for developing more stable routing protocols. We built a theoretical model to analysis the stability of the VANET topology, and provided the simulation experiment to verify the correctness of the theoretical analysis. Results show that the vehicle traveling in the same direction is easier to maintain the stability of the topology of a VANET, and the valid time of the path will decrease with the increase of the intersection angle in the direction of the vehicle movement, the vehicle movement velocity and the time. In addition, the simulation results also show that the bigger the initial distance among the vehicles is, the less stable the network topology is. The discovery of this phenomenon is important to develop zoned routing protocols.

A Multi-Authority Attribute-Based Encryption System Against Malicious KGC
Authors: Zhang Guo Yan
Published: September 2012

Attribute-based encryption scheme is a scheme in which each user is identified by a set of attributes, and some function of those attributes is used to determine decryption ability for each ciphertext. Similar with identity-based encryption scheme, attribute-based schemes are also confronted with key escrow problem. Furthermore, the attributes belonging to a user usually are monitored by different authorities. This paper resolves the two problems by using a general attribute-based encryption scheme and K-Sibling intractable function families. In our construction, different attributes sets of a user are still certified by different authorities, but the partial private keys corresponding to the attributes are generated by a central authority. Simultineously, different authorities jointly generate the users’ secret value which cannot be obtained by the central authority. Compared with general multi-authourity attributed-based encryption scheme, our approach has more efficiency.

Authors: Zheng Zi Wei
Published: September 2012

Faced with the challenges of modern communication, high data throughput requirements, extensive research has been paid to broadband modulation. The multi-carrier modulation is one of the most important wide band modulation techniques. Orthogonal frequency division multiplexing (OFDM) is an effective blow to the broadcast channel multipath fading and high bit rate transmission multi-carrier modulation technology of wireless channels, it is widely used in modern digital television terrestrial broadcasting (DTTB) system to support performance bandwidth-efficient multimedia services with the aid of inverse fast Fourier transform and fast Fourier transform operation. Multiple-antenna transmitter and receiver technology allows several times to achieve data transmission rates and spectrum efficiency and the use of multiple transmit antennas and multiple receive antennas through spatial processing. The Digital Terrestrial Multimedia Broadcasting (DTMB) system with the multiple-antenna receiver is considered in this paper. Digital Terrestrial Multimedia Broadcasting (DTMB) has three kinds of Frame Head mode with PN420/PN595/PN945 as training sequences for the time domain synchronous OFDM (TDS-OFDM). At the receiver side with multiple antennas, Frame Head mode detection should be done. In this paper, the frame synchronization scheme is proposed for the DTMB systems with the multiple-antenna receiver. System performance studies under different channel situations are used to verify the efficiency of the proposed scheme for the DTMB systems with the multiple-antenna receiver.

The assessment after rehabilitation is an important part of rehabilitation medicine, and of great significance for the basic research and clinical application for rehabilitation medicine. Physician can make objective analysis about patients’ present conditions, and then appropriate training program can be developed for patients to recover their body function more effectively. Three kinds of EMG signal, that is, the healthy, patient with myopathy, and patient with neuropathy, are involved. The complexity of the three types of signal is compared and the related variables (embedding dimension and time delay of phase space reconstruction) are determined by singular-value decomposition and mutual information method. Moreover, a novel effective approach improved from Hilbert-Huang Transform (HHT) is proposed here for the further comparision among the three EMG signals. The results show both methods can distinguish the three kinds of EMG signal clearly.

A Multi-Level Naïve Bayes Classifier for Sentiment Classification
Authors: Shi Jun Zheng , Guo Lei , Wei Shi Min
Published: September 2012

A great demand of sentiment classification comes with the rapid development of the internet. At present, the methods about sentiment classification based on machine learning have been widely used. The sentiment classification is a more difficult task, which needs more in-depth study than the traditional topic-based classification method [1]. Naïve Bayesian classifier is widely used in text classification. However, it requires two basic assumptions as its prerequisite and the performance would have been poor if these two were dissatisfied. We propose a multi-level naïve Bayes classifier to make up the deficiency of the traditional naïve Bayes classifier. The research below shows that the multi-level naïve Bayes classifier gets better performance than the traditional naïve Bayes classifier on the sentiment classification of movie reviews.

Published: September 2012

Scale recognition is the effective technology in underwater target identification. The existing methods can only solve the problem of single-target scale estimation and are not adaptable to the problem of multi-target scale estimation and recognition in complex counterwork. A method named FC based on fuzzy clustering analysis was put forward to analyze and estimate the multi-target scales in this paper. In the method, all the highlights collected by homing system were analyzed by dynamic fuzzy clustering with the principle of shortest distance, and scales were estimated separately based on the lights belonged to deferent sorts. Simulation results show that the problem of multi-target scale recognition can be solved effectively with FC method.

Published: September 2012

Geometric precision correction of remote sensing image plays a more and more important role in the application of high precision remote sensing. A reference image database is built up based on PostgreSQL, an open-source relation database, and ArcSDE, a widely used spatial data engine. Compared with single reference image, the reference image database has the advantages of managing convenience, lower-cost maintenance and high retrieval efficiency. Meanwhile, the correction accuracy is boasted by Gopfert algorithm , and efficiency is improved by advanced parallel model based on parallel I/O and I/O hidden strategy. Beyond this, combined with MapServer which can rapidly display images, a geometric precision correction system of high performance with dual servers is formed, with which mass production ability is achieved.

In traditional database domain, k-anonymity is a hotspot in data publishing for privacy protection. In this paper, we study how to use k-anonymity in uncertain data set, use influence matrix of background knowledge to describe the influence degree of sensitive attribute produced by QI attributes and sensitive attribute itself, use BK(L,K)-clustering to present equivalent class with diversity, and a novel UDAK-anonymity model via anatomy is proposed for relational uncertain data. We will extend our ideas for handling how to solve privacy information leakage problem by using UDAK-anonymity algorithms in another paper.

The reliability of a facility system is to a large degree adversely affected by the edge facility failures. In this paper, we consider the design of reliable facility systems based on the classical p-median problem subject to edge failures. A reliable model is formulated and a scenario based algorithm is applied for computing an instance. The results show that the reliability of a facility system will increase when considering the edge facility failures in locating decision.
Passengers Flow Forecasting Model of Urban Rail Transit Based on the Macro-Factors
Authors: Shang Bin , Zhang Xiao Ning
Published: September 2012

In China, many cities are planning urban rail transit system, but a comprehensive passenger flow estimation model is still lacking. The total passenger flow of urban rail transit in a city depends on many factors, such as urban population, total length of rail lines, gross domestic production of the city etc. To estimate the total passenger flow of urban rail transit, a linear regression model with multiple variables is established in the paper, based on the real data collected in many cities with urban rail transit operating. The comparison of the estimated flow and the real flow in many cities shows that the model is very accurate in passenger flow forecasting.
