Research on the Dynamic Hysteresis Loop Model of the Residence Times Difference (RTD)-Fluxgate
Authors: Wang Yanzhang , Wu Shujun , Zhou Zhijian , Cheng Defu , Pang Na , Wan Yunxia
Published: September 2013

Based on the core hysteresis features, the RTD-fluxgate core, while working, is repeatedly saturated with excitation field. When the fluxgate simulates, the accurate characteristic model of the core may provide a precise simulation result. As the shape of the ideal hysteresis loop model is fixed, it cannot accurately reflect the actual dynamic changing rules of the hysteresis loop. In order to improve the fluxgate simulation accuracy, a dynamic hysteresis loop model containing the parameters which have actual physical meanings is proposed based on the changing rule of the permeability parameter when the fluxgate is working. Compared with the ideal hysteresis loop model, this model has considered the dynamic features of the hysteresis loop, which makes the simulation results closer to the actual output. In addition, other hysteresis loops of different magnetic materials can be explained utilizing the described model for an example of amorphous magnetic material in this manuscript. The model has been validated by the output response comparison between experiment results and fitting results using the model.
A Security Analysis of the 802.11s Wireless Mesh Network Routing Protocol and Its Secure Routing Protocols
Authors: Tan Whye , Lee Sang-Gon , Lam Jun , Yoo Seong-Moo
Published: September 2013

Wireless mesh networks (WMNs) can act as a scalable backbone by connecting separate sensor networks and even by connecting WMNs to a wired network. The Hybrid Wireless Mesh Protocol (HWMP) is the default routing protocol for the 802.11s WMN. The routing protocol is one of the most important parts of the network, and it requires protection, especially in the wireless environment. The existing security protocols, such as the Broadcast Integrity Protocol (BIP), Counter with cipher block chaining message authentication code protocol (CCMP), Secure Hybrid Wireless Mesh Protocol (SHWMP), Identity Based Cryptography HWMP (IBC-HWMP), Elliptic Curve Digital Signature Algorithm HWMP (ECDSA-HWMP), and Watchdog-HWMP aim to protect the HWMP frames. In this paper, we have analyzed the vulnerabilities of the HWMP and developed security requirements to protect these identified vulnerabilities. We applied the security requirements to analyze the existing secure schemes for HWMP. The results of our analysis indicate that none of these protocols is able to satisfy all of the security requirements. We also present a quantitative complexity comparison among the protocols and an example of a security scheme for HWMP to demonstrate how the result of our research can be utilized. Our research results thus provide a tool for designing secure schemes for the HWMP.
Unfolding Education for Sustainable Development as Didactic Thinking and Practice
Authors: Madsen Katrine
Published: September 2013

This article’s primary objective is to unfold how teachers translate education for sustainable development (ESD) in a school context. The article argues that exploring tensions, ruptures and openings apparent in this meeting is crucial for the development of existing teaching practices in relation to ESD. The article draws on doctoral research involving interviews with researchers and teachers who have collaborated in ESD research and development projects at primary and secondary schools in two different countries, Denmark and Ireland. It is the teachers’ perspectives on the projects which form the analytical foundation; thus, it is the practices as seen from the ‘inside’. Furthermore, ESD practices are considered in a broader societal perspective, pointing to the critical power of the practice lens.
Les transformations du logis seigneurial de Dunois au château de Beaugency par Jean d'Orléans-Longueville au début du XVIe siècle
Authors: Bontemps Daniel
Published: September 2013

Der Umbau des herrschaftlichen Wohnsitzes von Dunois im Schloss von Beaugency durch Jean d'Orléans-Longueville zu Beginn des 16. Jahrhunderts, von Daniel Bontemps.

Das herrschaftliche Wohngebäude im Schloss von Beaugency, das Mitte des 15. Jahrhunderts von Dunois, dem berühmten sogenannten Bastard von Orléans, umgebaut und vergrößert wurde, ist bisher weitgehend unbekannt geblieben. Dennoch erlaubt es die Existenz von bislang ungenügend ausgewerteten Archivalien und Plänen des 17. und 18. Jahrhunderts, das Aussehen und die Funktionen der verschiedenen Teile dieses Wohnbaus, der zwischen 1516 und 1524 erneut umgebaut wurde, zu rekonstruieren. Es war Johann von Orléans-Longueville, Erzhischof von Toulouse, der den Wohnsitz seines Großvaters umbauen ließ. Er erbaute sich ebenso das gegenüber liegende, eigene Herrenhaus im Stil eler Frührenaissance. Unglucklicherweise sind davon nur Ruinen auf uns gekommen. Lediglich der angebaute, zeitgenössische Pavillon ist erhalten. Der Ptälat führte diese neue Kunstrichtung in Beaugency durch Baumeister und Steinmetzen ein, die von der Baustelle des Longueville-Flügels des Familienstammsitzes Schloss Châteaudun und aus Orléans kamen : Pierre Gadier, Pierre Chausse und Pierre Biard.
La collégiale Notre-Dame de Beaugency. Les campagnes romanes
Authors: Vergnolle Éliane
Published: September 2013

Although no text provides direct information concerning the construction of Notre-Dame de Beaugency, a study of the monument situates the starting point in the 1140s. Work continued diligently over two campaigns. The first campaign encompassed the erection of the entire east end and the implantation of the walls of the side aisles ; after a brief interval, the nave and west façade were in turn completed.

The ambitions of the lords of Beaugency are reflected in the chevet, ambulatory, radiating chapels and two-tower façade. In contrast, the sobriety of the décoration and the choice of a wooden roof supported by columns express the aspirations ofthe Augustinian community, established at Beaugency in the early twelfth century, to live in an atchitectural environment in keeping with their spiritual ideals. The talented master who built the chevet saw how to resolve this contradiction. By according extreme importance to the windows and by lightening the sttucture as much as possible, he also demonstrated the dynamism of Romanesque architecture in the Loire Valley, at a time when the first Gothic worksites were starting up in the Ile-de-France.
L'Hôtel de ville de Beaugency et sa restauration au XIXe siècle
Authors: Droguet Vincent
Published: September 2013

Das Rathaus von Beaugency ist ein seltenes Beispiel öffentlicher Gebaude der Renaissance. Erbaut zwischen 1526 und 1533, sticht es hervor durch seine Fassade, deren dekorative Formensprache sich ableitet von den großen Bauten derr Zeit um 1515, wie den Schlössern von Bury oder Blois (Flügel Franz' L). Berücksichtigt man den lokalen Kontext, so ist es denkhar, eine Beteiligung des Baumeisters Pierre Biart anzunehmen, det zur selben Zeit auch am Schloß von Beaugency tätig war.

Im Laufe der 1840er Jahre nahm Léon Vaudoyer das Gebaude auf und lieferte sogar eine Ergänzung nach derselben Methode, die Félix Duban gerade bei der Restaurierung des Flügels Franz' I. in Blois anwandte. Fünfzig Jahre spater, zwischen 1892 und 1898, restaurierte der Architekt René Dusserre das Bauwerk nach den Planen von Léon Vaudoyer und gab ihm damit sein uns heure vertrautes Aussehen.
Πιστοι ἑρμηνεῖς. La traduction orale en Grèce
Authors: Rochette Bruno
Published: September 2013

Cet article tente d'étudier les situations dans lesquelles les Grecs, confrontés à des langues étrangères — qu'ils connaissent sous l'appellation générique de « langues barbares» — ont dû recourir aux services d'interprètes. La terminologie utilisée montre qu'il existe une différence très nette entre traduction écrite — littéraire — et traduction orale. Ce sont surtout l'expédition des Dix Mille et les campagnes d'Alexandre le Grand qui mirent les Grecs en présence de langues étrangères. S'il existe des ἑρμηνεῖς attachés en permanence aux corps d'armée, c'est très souvent un soldat qui remplit cette fonction, parce qu'il se trouve qu'il connaît la langue du pays. La fonction d'interprète est connue tout au long de l'histoire de la Grèce, jusqu'à la conquête romaine et l'époque byzantine.
La moisson d'Héraklès : le héros, le domaine et les enfants dans les Trachiniennes
Authors: Dumanoir Jean-Richard
Published: September 2013

A la lumière des tragédies du retour, le rapport qu'entretient Héraklès avec Trachis fait apparaître le caractère fragile et factice du domaine. Le statut particulier des enfants s'explique par la fonction auquel il les destine : en tant que Moissonneur d'adolescents, il impose à Hyllos une épreuve initiatique qui participe d'un désir fondamental d'ἤβη chez ce héros, jusque dans sa nature et dans sa fonction de père. Aussi l'adaptation de Sophocle, en s'écartant obstinément de la version thébaine, propose-t-elle en fait, dans les actes mêmes du héros, une actualisation violente des vertus que la tradition légendaire et cultuelle retarde et n'exalte qu'après sa mort.
De la botanique à la poésie dans les Idylles de Théocrite
Authors: Amigues Suzanne
Published: September 2013

The large number of plant species mentioned by Theocritus in the Idylls makes one wonder how the poet could have known about them and, in this respect, how much was due to scientific knowledge and how much to creative imagination. Examples in the Idylls I, II and XIII show that the Theophrastus' Enquiry into Plants was the main source of information for Theocritus, completed by extracts from Homer and the Tragics, as well as by folklorist traditions. While respecting a certain botanical reality, the poet gives full symbolical value to the plants of his choice, and places them in the context of this fictional literature by a judicious use of recollections, allusions and premonitory signs.
« Dire en grec les choses juives ». Quelques choix lexicaux du Pentateuque de la Septante
Authors: Dorival Gilles
Published: September 2013

Pour les traducteurs de la Septante, un petit nombre de réalités bibliques ne sont pas traduisibles (cas des translittérations). Mais, en général, ils ont su faire comprendre les réalités du Pentateuque en les actualisant pour leurs lecteurs grecs grâce aux divers lexiques de leur temps. Certes ils ont dû parfois innover (mots, sens et emplois nouveaux), mais toujours dans le droit fil de la langue grecque. L'impression d'étrangeté éprouvée devant la Septante ne tient pas tant à son lexique qu'à sa syntaxe, que le lecteur grec devait toutefois finir par trouver acceptable.
À propos de l'Asclépieion de Messène : Asclépios poliade et guérisseur
Authors: Sineux Pierre
Published: September 2013

La relecture de l'ensemble des données concernant la présence d'Asclépios à Messène permet de montrer qu'au lendemain de la construction de la nouvelle Messène, Asclépios apparaît, parallèlement à l'héroïne Messénè, comme une divinité poliade. Ce caractère se renforce au tournant des IIIe et IIe siècles av. J.-C. avec la construction du complexe de l'Asclépieion, destinée à réaffirmer l'identité de la cité, alors menacée par les ambitions de la confédération achéenne. Toutefois, différents éléments de ce complexe (notamment la situation et le dispositif de la statue-bassin, l'existence de l'édifice pour le bain, la présence de divinités associées, dans les autres sanctuaires asclépiéiens, au rituel préliminaire à l'incubation) tendent à indiquer qu'Asclépios y a exercé aussi une fonction guérisseuse et que le rite d'incubation pouvait être accompli.
Planesiai, îles erratiques de l'Occident Grec
Authors: Moret Pierre
Published: September 2013

Trois îles de la Méditerranée occidentale, Pianosa en mer Tyrrhénienne, Saint-Honorat en Ligurie et Tabarca en Ibérie, portaient dans l'Antiquité le même nom grec, Planesia ou Planasia, qui signifiait «l'île errante». Sur le littoral maurétanien, l'Insula Errons mentionnée par une source latine se rattache sans doute à la même famille toponymique. L'arrière-fond mythique de la notion d'île errante ou mouvante est ensuite étudié. L'intervention d'un dieu qui immobilise et enracine l'île vagabonde est attestée à Délos — dont le premier nom, Asteria, a les mêmes connotations astrales que Planesia — , mais aussi à Tyr, sous les espèces d'un Héraclès-Melqart fortement hellénisé. Ces mythes de fondation autorisent une nouvelle lecture de la légende qui montre saint Honorât chassant les serpents et faisant sourdre l'eau douce sur l'île primitivement errante de Lérins.
Aristote, Corax, Anaximène et les autres dans la Rhétorique à Alexandre
Authors: Patillon Michel
Published: September 2013

La théorie des arts rhétoriques de l'antiquité grecque montre deux traditions, l'une, plus pratique, organisée selon les parties du discours judiciaire, l'autre, plus spéculative, organisée selon les tâches de l'orateur. Dans cet article on fait l'hypothèse que la Rhétorique à Alexandre nous propose des données primitives pour l'une et l'autre de ces traditions, et qu'il convient de les distinguer. Les chap. 29-37 sont l'essentiel d'un traité ancien, conçu selon les parties du discours et représenteraient la tradition coraxienne ancienne. Le reste du traité, dont la structure préfigure celle de la Rhétorique d'Aristote, est une synagogè technôn, regroupant des théories issues de la tradition sophistico-rhétorique (la première source possible de cette synthèse pourrait être Anaximène). — Toutes ces hypothèses s'appuient sur la discussion de sources primaires.
Μάρτυς chez Nonnos de Panopolis : étude de sémantique et de chronologie
Authors: Vian Francis
Published: September 2013

Une étude exhaustive des termes de la famille de μάρτυς dans l'œuvre de Nonnos révèle que le poète s'est constitué un système paraformulaire d'abord dans la Paraphrase de l'Évangile selon S. Jean afin de rendre les termes de μαρτυρέω et de μαρτυρία fréquents dans le texte johannique ; il l'a ensuite transporté et adapte dans les Dionysiaques. Cette analyse permet d'affirmer que la Paraphrase est antérieure aux Dionysiaques et qu'elle est une œuvre authentiquement nonnienne.
« À la mémoire de Herzen » : l’année 1912
Authors: Amacher Korine
Published: September 2013

«In Memory of Herzen » (1912)

At the beginning of the 20th century, in the circles of Russian liberal and radical members of the intelligentsia, anniversaries of some

figures of the social movement of the 19th century used to give rise to celebrations during which the question of heritage of the Russian ‘liberation movement’ was brought into focus. The case of Herzen is of special interest. Indeed, his openness and continuous evolution throughout his whole life are characteristic of his ideas and incited various ‘successors’ to lay claim to his heritage. Social democrats, liberals, socialists-revolutionaries – at the beginning of the 20th century, all of them wanted to be his successors. The largest number of texts had been written for the 100th anniversary of his birth in 1912. During this celebration, Herzen became a heroic and tragic figure of Russian emigration, an iconic figure of ‘spiritual father’, a figure of high moral standards who was able to overcome all kinds of ideological disagreements and to view the future of Russia with trust and pride. After the periods of despondency and political disappointments, Herzen was the symbol of belief in the future victory.
Radioelectric Asymmetric Conveyed Fields and Human Adipose-Derived Stem Cells Obtained with a Nonenzymatic Method and Device: A Novel Approach to Multipotency

Published: September 2013

Human adipose-derived stem cells (hASCs) have been recently proposed as a suitable tool for regenerative therapies for their simple isolation procedure and high proliferative capability in culture. Although hASCs can be committed into different lineages in vitro, the differentiation is a low-yield and often incomplete process. We have recently developed a novel nonenzymatic method and device, named Lipogems, to obtain a fat tissue derivative highly enriched in pericytes/mesenchymal stem cells by mild mechanical forces from human lipoaspirates. When compared to enzymatically dissociated cells, Lipogems-derived hASCs exhibited enhanced transcription of vasculogenic genes in response to provasculogenic molecules, suggesting that these cells may be amenable for further optimization of their multipotency. Here we exposed Lipogems-derived hASCs to a radioelectric asymmetric conveyer (REAC), an innovative device asymmetrically conveying radioelectric fields, affording both enhanced differentiating profiles in mouse embryonic stem cells and efficient direct multilineage reprogramming in human skin fibroblasts. We show that specific REAC exposure remarkably enhanced the transcription of prodynorphin, GATA-4, Nkx-2.5, VEGF, HGF, vWF, neurogenin-1, and myoD, indicating the commitment toward cardiac, vascular, neuronal, and skeletal muscle lineages, as inferred by the overexpression of a program of targeted marker proteins. REAC exposure also finely tuned the expression of stemness-related genes, including NANOG, SOX-2, and OCT-4. Noteworthy, the REAC-induced responses were fashioned at a significantly higher extent in Lipogems-derived than in enzymatically dissociated hASCs. Therefore, REAC-mediated interplay between radioelectric asymmetrically conveyed fields and Lipogems-derived hASCs appears to involve the generation of an ideal “milieu” to optimize multipotency expression from human adult stem cells in view of potential improvement of future cell therapy efforts.
Potential Barriers to Human Hepatocyte Transplantation in MUP–uPAtg(+/+)Rag2-/-γC-/-Mice
Authors: Komori Junji , Deward Aaron D. , Gramignoli Roberto , Strom Stephen C. , Fontes Paulo , Lagasse Eric
Published: September 2013

Primary human fetal and adult hepatocytes have been considered feasible donor cell sources for cell transplantation. We compared the engraftment efficiencies between adult human, fetal human, and adult porcine hepatocytes after transplantation into MUP–uPAtg(+/+)Rag2-/-γC-/-mice. Transplantation of adult human hepatocytes yielded a 1,000-fold higher serum albumin level compared to transplantation of fetal human hepatocytes, while transplantation of adult porcine hepatocytes resulted in a 100-fold higher serum albumin level than adult human hepatocytes. These results suggest that adult liver cells are superior to fetal liver cells for transplantation, and caution should be applied if porcine hepatocytes are used for preclinical studies as a proof of concept for human hepatocytes.
SCHEDULE CONTINGENCY ANALYSIS FOR TRANSIT PROJECTS USING A SIMULATION APPROACH
Authors: Gurgun Asli Pelin , Zhang Ye , Touran Ali
Published: September 2013

This paper presents a probabilistic method to establish schedule contingency levels based on percent completion of the project. The objective is providing a distribution for contingency for various percent completion levels which allows the project owner/manager to choose the schedule contingency at their comfort level. The proposed method is applied on real data from a number of US transit projects and actual schedule overruns for different phases of the project development (preliminary engineering, final design and construction) are analyzed. These values are used to establish the required contingency at the conclusion of each of the mentioned project phases. Additionally, using these values, the required contingency at various points during the construction phase (such as 25% and 50% completion) is calculated and reported. This approach can be used by project owners to plan realistic schedules during various phases of the project, providing better control on duration and the opportunity for being prepared to take necessary action in case the available schedule contingency falls below reasonable levels.
IMPROVED PSO ALGORITHM FOR SHAPE AND SIZING OPTIMIZATION OF TRUSS STRUCTURE
Authors: Li Yancang , Peng Yang , Zhou Shujing
Published: September 2013

In order to overcome the premature convergence defect of the basic particle swarm optimization (PSO) algorithm and provide an effective method for shape and sizing optimization of truss structure, an improved PSO was proposed. The random direction method was employed to produce high-quality initial population, the fuzzy system was applied in the dynamic adaptive adjustment of parameters of the PSO, and the Metropolis criteria were used to improve the performance of PSO. Then, the improved PSO was introduced to the truss structure shape and sizing optimization design. Engineering practice and comparison with the other optimization algorithms show that the algorithm has good convergence and global searching capability. The study provides a promising algorithm for the structural optimization.

Authors: Abdallah Moatassem , Marzouk Mohamed
Published: September 2013

Tunnel construction is one of the important infrastructure projects, which is vital for enhancing the transportation networks, especially in congested cities. Tunnel projects are characterized by long durations, large budgets, complexities, repetitive construction tasks, risks, and uncertainties. Several construction techniques have been developed in the tunnel construction industry to improve the constructability of tunnels and decrease the impact on surrounding structures. This paper presents a framework for planning tunnel construction using computer simulation. The proposed tool aids contractors in estimating the required time and cost for construction. Five tunnel construction techniques have been considered in the development of this tool with different ground supporting techniques. The proposed framework consists of three modules: (1) tunnel analyzer module, (2) simulation module, and (3) decision support module, and is capable of selecting the best construction technique using fuzzy group decision-making method based on time, cost and other selection criteria that could be defined during the decision-making phase. This decision method ranks alternatives based on a group of experts and a predefined set of criteria. Numerical examples are introduced to illustrate the capabilities of the proposed framework.

Published: September 2013

Objective.

E-cadherin is a potent adherens junction molecule implicated in tissue morphogenesis, epithelial functioning, and immune regulation. Serum levels of soluble E-cadherin (sE-cadherin), an end product of proteolytic cleavage of E-cadherin, is increased in patients with cancer, infections, and inflammation-related diseases. The aim of our study was to measure serum levels of sE-cadherin in systemic lupus erythematosus (SLE) and to determine associations between serum levels of sE-cadherin and markers of inflammation and organ damage in female patients with SLE.

Methods.

Serum levels of sE-cadherin were analyzed by ELISA in 150 female patients with SLE and 31 healthy women. Simple and multiple regression analyses between sE-cadherin levels and disease-related variables were performed in patients with SLE.

Results.

Serum levels of sE-cadherin were elevated in patients with SLE compared with levels in healthy controls. sE-cadherin levels correlated positively with age, disease duration, SLE Collaborating Clinics Damage Index, erythrocyte sedimentation rate (ESR), s-creatinine, cholesterol, triglycerides, interleukin 6, and matrix metalloproteinase-3. In multiple regression analysis, s-creatinine, age, ESR, and triglycerides remained determinants of sE-cadherin. Within the patients with SLE, higher sE-cadherin levels were found only in patients with renal damage, i.e., s-creatinine > 90μmol/l, glomerular filtration rate < 50 ml/min, or renal involvement ever by SLE.

Conclusion.

Our study demonstrates significantly elevated serum levels of sE-cadherin in women with SLE compared with healthy women. The levels of sE-cadherin were positively correlated to s-creatinine, age, ESR, and triglycerides. Significantly elevated sE-cadherin levels were observed only in patients with renal damage.
All Common Subsequences for Face Recognition
Authors: Wang C.H. , Hu A.K. , Han F. L.
Published: September 2013

In recent years, face recognition has become one of the hottest research topics aimed at biometric applications. Comparing with other biometrics recognition, face recognition provides more natural means for perceptual interface. However, face recognition algorithms weakly perform under some common conditions, which include the variation of facial expressions or lightening conditions, the occlusion of faces like wearing glasses or mask, the low resolution or noises of input images, and the like. The other problem is the recognition efficiency, especially when the facial database is tremendous. This paper presents all common subsequences (ACS) as the kernel function (similarity method) to solve the time series problem. Experiments on 4 public face databases: Caltech, Jaffe, Orl and Yale databases, demonstrate that ACS can achieve higher recognition accuracy than some classic face recognition methods, e.g. 2DPCA and 2DLDA.These instructions give you basic guidelines for preparing camera-ready papers for conference proceedings.

Authors: Wang Lin Yu , Mao Lei
Published: September 2013

In order to have comprehensive understanding and better application about Modal fibers, the microstructure of Lenzing Modal (MD), Birla Modal (BLM) and Formotex Modal (FM) siro-spun yarn was investigated by XRD and FTIR spectroscopy. The tensile properties of the yarn were measured by an Instron tensile tester, the hairiness and boiling shrinkage of the three kinds modal siro-spun yarn were also investigated. The results indicate that the main chemical component of the three kinds of modal yarn are all cellulose. However, the MD shows a higher crystallinity and breaking tenacity when compares with BLM and FM. All the three kinds of modal siro-spun yarn show excellent applied properties, the hairiness and boiling shrinkage of the three kinds of yarn are small.

Published: September 2013

The organic ligand sulfosalicylic acid (SSA) which was selected as molecular bridge for sensitization of terbium ions was modified by thionyl chloride (SOCl2) and 3-ammonium propyl triethoxy silane (APTES) to obtain the hybrid precursor SSA-Si. Then the solution of Tb (NO3)3was added in the presence of tetraethylorthosilicate (TEOS). The binary lanthanide organic/inorganic hybrid material was obtained. The ternary hybrid material was obtained by adding the solution of Tb (NO3)3and polyurethane. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Tb-(SSA-Si)3, the ternary mesoporous material Tb-(SSA-Si)3-PU exhibits the characteristic emission of the Tb3+ion with a higher luminescence intensity, suggesting that the introduction of polymer polyurethane into the mesoporous matrix is of benefit for the sensitization of Tb3+luminescence, by replacing H2O groups that can quench the luminescence of Tb3+ion.

Published: September 2013

Hot stamping of the ultra high strength steel (UHSS) was studied to meet the requirements of lightweight of automobile. The coupled thermo-mechanical model for hot stamping was established with ABAQUS. Initial temperature of tools (die, punch, blank holder) and stamping speed were studied to insure the impact on the thickness, stress and strain of blank. It shows that punch fillet area is easy to crack. With the temperature of tools increasing, the sheet minimum thickness increases first and then decreases. With the increase of punch velocity, the sheet minimum thickness increases. Compared with the initial temperature of tools, punch velocity has a greater impact on the thickness. The simulation results are in agreement with the experimental results and provide a theoretical basis for the practical stamping process.

Published: September 2013

The thermoplastic processing and mechanical properties of starch were investigated by different plasticization methods. Glycerol was chosen as the plasticizer for starch. The effect of glycerol with different amount was studied. The two plasticizing methods of direct adding and high-speed mixing of glycerol were used to plasticize starch, respectively. The results showed that the suitable processing temperatures ranged from 105°C to 140°C. The tensile strength of the obtained thermoplastic starch decreased and the breaking elongation ratio increased with the increase of glycerol content. When the percent of glycerol was 30%, the extrudate of platicized starch has excellent liquidity and the appearance of the extrudate was smooth. Compared with the plasticizing method of direct adding, the plasticization method of high-speed mixing is more beneficial to plasticize starch.

Published: September 2013

in order to improve the efficiency and validity of node importance evaluation, a new evaluation method for node importance in complex networks was proposed based on node approach degree and node correlation degree. The basic idea of the method is that the larger the approach degree of a node is, the closer to center of a complex network the node is and the more important it is; the bigger the correlation degree of a node is, the more important the node is. An evaluation algorithm corresponding to the method was designed for the warship fleet cooperation anti-missile network. Finally, the validity of the proposed method was verified by simulation experiments.

Authors: Chen Yu Min , Wu Jing Yang , Zeng Fei , Gao Xiang , Bi Xiao Mei
Published: September 2013

The classification of geographical information services is very important to the effective management and sharing of geographical spatial information, especially in a web-based GIS system. However, most current classification criteria focus on an abstract level. Discussions on the detailed services classification are still insufficient. This paper proposes a new thought of constructing these diverse services using the Formal Concept Analysis (FCA). After briefly discussing the current services classification systems and basic knowledge of FCA, the paper takes vector data spatial statistic analysis as an example to perform the classification with the method of FCA. The resultant categories prove to be acceptable and practical.

The spatial data presented several characteristics of mass, multiple, isomerism and multiple tenses, its organization and management mechanism is an important direction of research for Digital Earth. The management of grave emergency with regards to a series of spatial and non-spatial data concerning gathering and handling, having put a higher demand forward the ability of information gathering mechanism on client. The current existing client access mechanism such as C/S model lacks of unified data exchange standards, similarly, B/S model cannot handle the spatial data effectively. It is also difficulty to display for complex and massive spatial data in visualized and real-time. That efficiency depends entirely on the network environment and performance of storage equipment. In order to realize the massive spatial data unified dispatching and efficient sharing based on the principle of Information-gathering and Service-polymerization. We put forward a concept of Spatial-data-cloud which based on G/S model, supported by HGML as the standard and criterion of spatial data exchange, presentation, organization, storage and management. It could also be set up a new work mechanism which use Geo-information browser polymerization multiple and massive complex spatial and non-spatial data. This will provide us a lightweight client called Geo-information browser with which is by the principle Information-gathering and Service-polymerization. It provides emergency management for technical supports such as intelligent decision support, comprehensive research and judgment, and rapid disposal etc. It is the development of basic research of a novel model of Digital Earth.

A Detection Algorithm to Anomaly Network Traffic Based on Spectral Kurtosis Analysis
Authors: Jiang Ding De , Yao Cheng , Zhang Wei Han , Xu Zheng Zheng
Published: September 2013

This paper presents a detection algorithm for anomaly network traffic, which is based on spectral kurtosis analysis. Firstly, we turn network traffic into time-frequency signals at different scales. These time-frequency signals hold the more detailed nature corresponding to different scales. Secondly, the time-frequency signals at different scales are transformed into a series of new time signals by time-frequency analysis theory. These new time signals hold obvious narrowband nature and embody the local properties of network traffic. Thirdly, we calculate the spectral kurtosis values of the new time signals and then perform the feature extractions. As a result, the abnormal network traffic can be correctly identified. Simulation results show that our algorithm is feasible and promising.
