Modelisation de la propagation de fractures hydrauliques par la methode des elements finis etendue

La permeabilite des roches est fortement influencee par la presence de fractures car ces dernieres constituent un chemin preferentiel pour l'ecoulement des fluides. Ainsi la presence de fractures naturelles est un facteur determinant pour la productivite d'un reservoir. Dans le cas de roches a faible conductivite, des techniques de stimulation telle que la fracturation hydraulique sont utilisees pour en augmenter la permeabilite et rendre le reservoir exploitable d'un point de vue economique. A l'inverse, dans le cas du stockage geologique, la presence de fractures dans la roche represente un danger dans la mesure ou elle facilite le transport et la migration des especes disseminees dans la roche. Pour le stockage de CO2, les fuites par les fractures presentes dans les couvertures du reservoir et la reactivation des failles constituent un risque majeur. Et en ce qui concerne le stockage geologique de dechets radioactifs, la circulation de fluide dans des reseaux de fractures nouvelles ou reactivees au voisinage de la zone de stockage peut aboutir a la migration de materiaux nocifs. Il est donc important de prevoir les effets de la presence de fractures dans un reservoir. Le but de cette these est le developpement d'un outil numerique pour la simulation d'un reseau de fractures et de son evolution sous sollicitation hydro mecanique. Grace a sa commodite, la methode des elements finis etendue (XFEM) sera retenue et associee a un modele de zone cohesive. La methode XFEM permet en effet l'introduction de fissures dans le modele sans necessairement remailler en cas de propagation des fissures. L'ecoulement du fluide dans la fissure et les echanges de fluide entre la fissure et le milieu poreux seront pris en compte via un couplage hydro mecanique. Le modele est valide avec une solution analytique asymptotique pour la propagation d'une fracture hydraulique plane dans un milieu poroelastique en 2D comme en 3D. Puis, nous etudions la propagation de fractures hydrauliques sur trajets inconnus. Les fissures sont initialement introduites comme des surfaces de fissuration potentielles etendues. Le modele de zone cohesive separe naturellement les domaines adherents et ouverts. Les surfaces potentielles de fissuration sont alors actualisees de maniere implicite par un post traitement de l'etat cohesif. Divers exemples de reorientation de fissures hydrauliques et de competition entre fissures voisines sont analyses. Enfin, nous presentons l'extension du modele aux jonctions de fractures hydrauliques
Learning a dual language vector space for domain specific cross lingual question retrieval
Venue: 2016 31st IEEE/ACM International Conference on Automated Software Engineering (ASE)

The lingual barrier limits the ability of millions of non English speaking developers to make effective use of the tremendous knowledge in Stack Overflow, which is archived in English. For cross lingual question retrieval, one may use translation based methods that first translate the non English queries into English and then perform monolingual question retrieval in English. However, translation based methods suffer from semantic deviation due to inappropriate translation, especially for domain specific terms, and lexical gap between queries and questions that share few words in common. To overcome the above issues, we propose a novel cross lingual question retrieval based on word embed dings and convolutional neural network (CNN) which are the state of the art deep learning techniques to capture word and sentence level semantics. The CNN model is trained with large amounts of examples from Stack Overflow duplicate questions and their corresponding translation by machine, which guides the CNN to learn to capture informative word and sentence features to recognize and quantify semantic similarity in the presence of semantic deviations and lexical gaps. A uniqueness of our approach is that the trained CNN can map documents in two languages (e.g. Chinese queries and English questions) in a dual language vector space, and thus reduce the cross lingual question retrieval problem to a simple k nearest neighbors search problem in the dual language vector space, where no query or question translation is required. Our evaluation shows that our approach significantly outperforms the translation based method, and can be extended to dual language documents retrieval from different sources.
Successful aging for low income older adults: towards design principles
Venue: PervasiveHealth

Low income older adults are at risk of poor health outcomes due to rising healthcare costs. When designed to reflect their needs, technologies can provide a cost effective solution to this problem. We investigated the issues and strategies low income people encounter in managing their health by conducting interviews and focus groups with fifty older adults. The qualitative analysis revealed eight main themes participants considered important for successful aging. Based on these findings, we propose two design principles to promote successful aging in the target population: (a) support shift and persist strategies; and (b) combat impoverished mentalities by providing knowledge, resources and motivation.
Diging simulation of a narrow trench

In this paper, we realized digging process simulation for a narrow trench using special equipment located at a mini excavator. These types of machines digging perform the longitudinal direction to the direction of travel, making trenches with widths of 0.4 m and depths of 3.5 7.0 m. These are necessary for the location of underground cables or draining water in agriculture. For Parametric modelling of parts included in ensemble has used software from Siemens NX 7.5, we produce sketches of each piece, using following commands: Sketch, Profile (Line) Arc, Circle, Quick Trim Quick Extend, Constraints. Depending on the layout of each piece can also use other commands such as: Chamfer, Rotate, Mirror Curve, Offset Curve, etc. After completion of sketch and dimensioning commands was: Extrude, Revolve, and at this stage the play may various modifications such as drilling, removal of certain volumes of piece showing various forms or change the appearance of surfaces (thread cutting, bevelling) This paper was realized with this parametric modelling software because presents major advantages including: control over the design, making design speed and increasing productivity; increasing product quality, reducing design risk recovery and time work, less human effort and reduced financial resources throughout the process.
Identification of Suitable Natural Inhibitor against Influenza A (H1N1) Neuraminidase Protein by Molecular Docking
Venue: Genomics informatics

The influenza A (H1N1) virus, also known as swine flu is a leading cause of morbidity and mortality since 2009. There is a need to explore novel anti viral drugs for overcoming the epidemics. Traditionally, different plant extracts of garlic, ginger, kalmegh, ajwain, green tea, turmeric, menthe, tulsi, etc. have been used as hopeful source of prevention and treatment of human influenza. The H1N1 virus contains an important glycoprotein, known as neuraminidase (NA) that is mainly responsible for initiation of viral infection and is essential for the life cycle of H1N1. It is responsible for sialic acid cleavage from glycans of the infected cell. We employed amino acid sequence of H1N1 NA to predict the tertiary structure using Phyre2 server and validated using ProCheck, ProSA, ProQ, and ERRAT server. Further, the modelled structure was docked with thirteen natural compounds of plant origin using AutoDock4.2. Most of the natural compounds showed effective inhibitory activity against H1N1 NA in binding condition. This study also highlights interaction of these natural inhibitors with amino residues of NA protein. Furthermore, among 13 natural compounds, theaflavin, found in green tea, was observed to inhibit H1N1 NA proteins strongly supported by lowest docking energy. Hence, it may be of interest to consider theaflavin for further in vitro and in vivo evaluation.
Discovery of Novel Pyrazole Derivatives as Potent Neuraminidase Inhibitors against Influenza H1N1 Virus
Venue: Archiv der Pharmazie

Ten pyrazole derivatives were synthesized and evaluated for their ability to inhibit the replication of influenza virions. All the compounds were synthesized in good to excellent yield, and the structures were ascertained with the help of 1H NMR, 13C NMR, mass, and elemental analysis. Among the tested series, compound 4i was identified as the most potent analog against the H1N1 virus, with IC50 5.4 uM, while the rest of the compounds showed mild to moderate inhibition of infection. Moreover, these compounds showed excellent inhibitory activity against influenza A neuraminidase (NA) with IC50 values ranging from 2.15 to 7.54 uM, among which compound 4i showed the most prominent inhibition with IC50 1.32 uM. To further exemplify the molecular contacts with NA, a molecular docking study of 4i was conducted with the 3D crystal structure of enzyme H5N1 NA in complex. Results showed that target molecules interact in a similar fashion with oseltamivir and zanamivir by creating interatomic contacts with Trp178, Glu227, and Arg371. Moreover, in the toxicity assay with the porcine renal proximal cell line, LLC PK1, the confocal images showed no appreciable change in morphological character at the highest tested dose.

Are Australian fans of anime and manga motivated to learn Japanese language?

Recent research into Japanese as a foreign language education has strongly emphasized the link between Japanese popular culture and learning Japanese. However, these studies have only targeted Japanese language learners in formal education contexts and have largely ignored those who are not studying Japanese or studying Japanese informally. This present study claims that it is premature to link the two in this way. Using the notions of public pedagogy, the continuum of informal formal learning, and out of school curriculum as our theoretical underpinnings, we examine how a cohort of fans deals with learning Japanese and about Japan in relation to their consumption of Japanese manga and anime. The results of an online survey of 451 Australia based manga and anime fans reveal that their interest in and motivation to consume these media may not necessarily lead them to enter into formal Japanese language education.
Characterization of 300 GHz Wireless Channel on a Computer Motherboard
Venue: IEEE Transactions on Antennas and Propagation

This paper presents characterization of 300 GHz wireless channel on a computer motherboard, where several different measurement scenarios have been considered. Results indicate that the presence of the ground plane and/or vertical parallel plate structures in the channel introduces multipath that, if constructively superimposed, may create a path loss lower than free space propagation path loss. In addition, it has been found that a few centimeters of vertical misalignment between the transmitter and the receiver result in a path loss greater than 5 dB. Furthermore, the results indicate that vertical components such as dual in line memory modules with reflection coefficient close to one for all incident angles can be used to create directed non line of sight (LoS) links with wide coherence bandwidth. Finally, for LoS propagation obstructed by large objects, such as a heatsink, the path loss exponent of 1.77 is found, while the rotating fan causes periodic fading in the received power, indicating that channel equalization techniques will be needed to overcome deep fades. All these results indicate that optimal communications can be achieved by carefully positioning the antennas with respect to the motherboard layout.

Behavioral lessons from Flipkart's Big Billion Day sale

The purpose of this paper is to understand the behavioral lessons and managerial implications of deep discount strategies used by e commerce firms to gain a competitive advantage over rivals. The paper seeks to understand the behavioral aspects of consumer and competitor response to such online sales, particularly with reference to e satisfaction and e loyalty. The case study seeks to: understand the behavioral aspects of utility and customer satisfaction; understand the behavioral aspects influencing customer attitudes, preferences and choice; understand heuristics involved in consumer decision making; and understand possible firm strategies based on a thorough analysis of behavioral influencers of customer decisions.  The paper follows a case study approach. Secondary data sources from the library, company website and newspaper articles have been used to build a case which would encourage students to discuss and analyze the application of principles of behavioral economics to marketing problems faced especially by e retailers. It uses Flipkart's botched up Big Billion Day sale to drive home lessons in behavioral economics to marketers.  With growing internet penetration, e retail presents high potential in India along with its BRICS peers. However, the task of grabbing customer mindshare, as also a share of wallet of the growing Indian purchasing power through monster discounts and deals by e tailers may not work. Firms such as Flipkart may strategize using principles of behavioral economics including confirmatory bias, framing effects, reference points, principles of loss aversion, heuristics and the peak end rule to influence customer decision making in their favor. They must also guard against any incidents/events which invoke the representativeness heuristic or negative confirmatory biases towards e commerce portals.  E tailers in countries like India should understand the behavioral implications of deep discount strategies and deals offered by them as a means of gaining competitive advantage. Attention to e service outcome quality and e service recovery is important.  The case is unique in its applications of behavioral economics principles to e retailing in India. It seeks to apply behavioral principles to a major e commerce marketing event in India. With the e commerce industry likely to boom in India, the case study provides unique insights into competitive pricing strategies adopted by e retailers and the feasibility thereof.

Weed and Water Law: Regulating Legal Marijuana

Marijuana is nearing the end of its prohibition in the United States. Arguably the country's largest cash crop, marijuana is already legal for recreational use in Colorado, Washington, Oregon, Alaska, and Washington DC. Between now and election day 2016, an additional 14 states may place marijuana legalization initiatives on their ballots. In addition, 23 states and Washington DC have legalized medical marijuana, with up to seven states pending legislation. The era of marijuana prohibition is rapidly coming to a close.At the same time, traditional doctrines of water law are struggling to cope with the modern realities of water scarcity. Administrative agencies lack capacities to monitor and enforce water rights in real time amid rapidly changing conditions. As marijuana cultivation leaves the black market and enters state regulatory frameworks, legal doctrines and administrative agencies will need to adapt in order to balance existing water rights with the demands of marijuana production. Failure to do so will encourage producers to remain clandestine while perpetuating existing conflicts between legal and illegal water users. At present there is a gap in understanding the relationship between water rights and marijuana legalization, despite their rapid convergence.This Article is the first to systematically address that gap. The study begins by describing status quo marijuana production taking place outside the context of state water law doctrines, and the unsustainable conditions that often result.  III and IV envision a legal marijuana market governed by the predominant doctrines of US water law: prior appropriation and riparianism. In Section V the theoretical becomes reality, as California's complex water laws are put to the test by the largest marijuana cultivation community in the United States. Section VI concludes with recommendations for states in the process of legalization. Broadly speaking, this Article finds that both common law and regulatory approaches to water allocation are capable of accommodating legal marijuana cultivation, but to minimize disruptions to existing water rights and the marijuana industry, state agencies will need to proactively adapt to the new realities of the legal marijuana economy.
From mind wandering to involuntary retrieval: Age related differences in spontaneous cognitive processes
Venue: Neuropsychologia

The majority of studies that have investigated the effects of healthy aging on cognition have focused on age related differences in voluntary and deliberately engaged cognitive processes. Yet many forms of cognition occur spontaneously, without any deliberate attempt at engaging them. In this article we review studies that have assessed age related differences in four such types of spontaneous thought processes: mind wandering, involuntary autobiographical memory, intrusive thoughts, and spontaneous prospective memory retrieval. These studies suggest that older adults exhibit a reduction in frequency of both mind wandering and involuntary autobiographical memory, whereas findings regarding intrusive thoughts have been more mixed. Additionally, there is some preliminary evidence that spontaneous prospective memory retrieval may be relatively preserved in aging. We consider the roles of age related differences in cognitive resources, motivation, current concerns and emotional regulation in accounting for these findings. We also consider age related differences in the neural correlates of spontaneous cognitive processes.
