Influence des interfaces dans le transfert du virtuel au réel

La thematique generale de notre these porte sur le transfert virtuel/reel de connaissances spatiales, et plus particulierement sur l’identification de variables susceptibles d’optimiser ce transfert. Notamment, nous nous sommes interesses a l’influence des interfaces de deplacement, de l’engagement physique et des informations sensorielles relatives au corps sur l’acquisition et le transfert de connaissances spatiales du virtuel vers le reel. L’engagement physique a ete manipule a l’aide de deux interacteurs (tapis roulant Vs joystick) proposant respectivement un fort et un faible engagement physique, ainsi que par une Interface Cerveau Ordinateur (ICO), permettant de commander un deplacement a l’aide de l’activite cerebrale du sujet, supprimant ainsi toute composante motrice effective. Enfin nous avons egalement manipule l’expertise en jeu video, variable susceptible de jouer un role important dans l’acquisition et l’utilisation des competences spatiales au sens large, et plus specifiquement dans le transfert virtuel-reel.Nos experimentations consistaient a apprendre un trajet a l’aide d’une des situations d’interaction definie ci-dessus. Le transfert virtuel/reel des connaissances spatiales a ete ensuite evalue a l’aide de 6 tâches : une tâche de classification chronologique de photos, une tâche d’estimation de la distance parcourue et une tâche d’estimation de directions (tâches egocentriques) ; une tâche de croquis du trajet, une tâche d’estimation de la direction du point de depart du trajet (tâche allocentrique) ; et enfin une tâche globale de wayfinding consistant a reproduire en environnement reel le trajet prealablement appris en virtuel.Nos resultats montrent que les effets de l’engagement physique (en particulier des informations proprioceptives et vestibulaires) et de l’expertise en jeu video sont differents selon la nature de la competence spatiale sollicitee (composante egocentrique, allocentrique ou reproduction du parcours). De plus, les resultats obtenus a l’aide de l’ICO permettent de preciser le role de la composante motrice dans l’acquisition et le transfert virtuel/reel de competences spatiales.L’ensemble de ces donnees sont discutees au regard des modeles d’acquisition et d’utilisation des connaissances spatiales, tels que le modele Landmark-Route-Survey et la theorie des graphes. Les perspectives de notre travail concernent le developpement d’interfaces adaptees aux utilisateurs ainsi que l’entrainement ou le reentrainement des competences spatiales de sujets âges ou de patients presentant des pathologies lesionnelles et/ou degeneratives.
Prediction of Peptides Binding to Major Histocompatibility Class II Molecules Using Machine Learning Methods

In daily life,we are frequently attacked by infection organisms such as bacteria and viruses. Major Histocompatibility (MHC) molecules have an essential role in T-cell activation and initiating an adaptive immune response. Development of methods for prediction of MHC-Peptide binding is important in vaccine design and immunotherapy. In this study, we try to predict the binding between peptides and MHC class II. Support vector machine (SVM) and Multi-Layer Percep-tron (MLP) are used for classification. These classifiers based on pseudo amino acid compositions of data that we ex-tracted from PseAAC server, classify the data. Since, the dataset, used in this work, is imbalanced, we apply a pre-processing step to over-sample the minority class and come over this problem. The results show that using the concept of pseudo amino acid composition and applying over-sampling method, increases the performance of predictor. Fur-thermore, the results demonstrate that using the concept of PseAAC and SVM is a successful method for the prediction of MHC class II molecules.
Rhamnose Binding Protein as an Anti-Bacterial Agent—Targeting Biofilm of Pseudomonas aeruginosa

More than 80% of infectious bacteria form biofilm, which is a bacterial cell community surrounded by secreted polysaccharides, proteins and glycolipids. Such bacterial superstructure increases resistance to antimicrobials and host defenses. Thus, to control these biofilm-forming pathogenic bacteria requires antimicrobial agents with novel mechanisms or properties. Pseudomonas aeruginosa, a Gram-negative opportunistic nosocomial pathogen, is a model strain to study biofilm development and correlation between biofilm formation and infection. In this study, a recombinant hemolymph plasma lectin (rHPLOE) cloned from Taiwanese Tachypleus tridentatus was expressed in an Escherichia coli system. This rHPLOE was shown to have the following properties: (1) Binding to P. aeruginosa PA14 biofilm through a unique molecular interaction with rhamnose-containing moieties on bacteria, leading to reduction of extracellular di-rhamnolipid (a biofilm regulator); (2) decreasing downstream quorum sensing factors, and inhibiting biofilm formation; (3) dispersing the mature biofilm of P. aeruginosa PA14 to improve the efficacies of antibiotics; (4) reducing P. aeruginosa PA14 cytotoxicity to human lung epithelial cells in vitro and (5) inhibiting P. aeruginosa PA14 infection of zebrafish embryos in vivo. Taken together, rHPLOE serves as an anti-biofilm agent with a novel mechanism of recognizing rhamnose moieties in lipopolysaccharides, di-rhamnolipid and structural polysaccharides (Psl) in biofilms. Thus rHPLOE links glycan-recognition to novel anti-biofilm strategies against pathogenic bacteria.
Isotherm Studies of Adsorption of Cr (Vi) Ions onto Coconut Husk

In this study, the application of ground coconut husk GCH for removal of Cr (VI) from its aqueous solution was investigated. Several batch experiments were carried out with different values of test conditions including sorbent concentration, contact time, temperature and pH. The results obtained showed that adsorption of Cr (VI) followed Freundlich isotherm model. Dubinin-Radushkevich isotherm revealed that adsorption of the three metal ions principally followed chemical adsorption process. Adsorption kinetics was best described by pseudo-second order. Thermodynamic studies revealed that adsorption of Cr (VI) were endothermic process since ∆H was positive. Adsorption of Cr (VI) was spontaneous as evident from the negative value ∆G. Uptake of metal ion from their aqueous solution increases with increase in pH but decreases slightly at pH of 8.
Modeling of the Total Alkalinity and the Total Inorganic Carbon in the Mediterranean Sea

Measurements of the CO2 system parameters in the Mediterranean Sea are relatively scarce and not representative for all its sub-basins. High quality data collected on May 2013 during the 2013 MedSeA cruise covering the whole basin were used to provide for the first time linear relationships estimating the total alkalinity (AT) and the total dissolved inorganic carbon (CT) from salinity in each Mediterranean basin and sub-basin at different depth layers. These correlations show that a substantial quantity of alkalinity is added to the seawater during its residence time in the Mediterranean Sea, whereas the biological processes, the air-sea exchange and the high remineralization rate are responsible of the high CT concentrations in this sea. Moreover, these fits could be used to estimate the AT and CT from salinity where there are not available measurements of the carbonate system parameters.
Emotion Recognition Based on General-ized Gamma Distribution

It is highly difficult to identify the emotions of a person. Literature accessible to recognize the emotions in case of immobilized personnel is limited to the outcome obtainable from the machines only. In this process, brain computer communication is utilized using neuro-scan machines like Encephalography (EEG), to recognize the feeling of immobilized persons. It uses the physiological signals accessible from EEG data extracted from the brain signals of immobilized personnel and tries to find out the emotions, but these results vary from machine to machine, and there exists no consistency by which one can identify the thoughts of the brain diseased personnel precisely. In this manuscript a novel technique is projected by using Generalized Gamma Mixture models (GGMM). The advantage of considering GGMM is its ability of extracting the emotions closely even in a noisy environment. The outcomes of the proposed method exceed the accuracy rates of conventional systems.
Using mobile phone telemetry to investigate the haul-out behaviour of harbour seals Phoca vitulina vitulina

Information on the haul-out behaviour of pinnipeds is essential for increasing the accu- racy of population estimates necessary for the effective conservation of protected species, as well as improving survey design. The haul-out behaviour of 10 harbour seals Phoca vitulina L. in southwest Ireland was examined using a novel telemetry system based on global systems for mobile communi- cations technology. The data on the haul-out patterns of tagged individuals were examined using generalised additive modelling to determine potential factors of influence, such as the tide, the time of day and the time of year. The behaviour varied among seals, with time ashore reaching a maxi- mum during post-moult in October and decreasing to a minimum in February. A strong tidal in- fluence on haul-out behaviour was evident. Tagged seals hauled out more frequently at low tide. There was variation between individuals in the influence of time of day on haul-out behaviour. A cyclic pattern with lunar periodicity was evident in seals tagged in October, and the pattern varied between tidal periods. There was an overall large variation in patterns of behaviour over the tagging period, both between individuals and between tidal periods for each individual. This cautions against making inferences on the haul-out behaviour of the 'population' based on the behaviour of a small number of tagged individuals. The present study provides detailed information, heretofore unavail- able, on the haul-out behaviour of individual harbour seals and on the behaviour of the species in Ireland, and it has important implications for population assessment for conservation purposes across the species' entire geographical range.
Mycotoxins Co-contamination in Corn Grains

In this paper, we present the results of a research on 36 samples of maize. Mycotoxicological analyses showed that the most present mycotoxins were of the Fusarium mycotoxins group. During 2011, the maize samples were tested for the presence and content of total aflatoxins (AFB1, AFB2, AFM1, AFM2), deoxynivalenol (DON), zearalenone (ZON) and fumonisins (FUM). According to the results that we obtained through the research period i.e. vegetation year 2011, mycotoxicological profile for most maize samples was DON ‒ FUM ‒ ZON. DON mycotoxin was predominantly present in 2011. Precautionary measures are required especially with lower concentrations of mycotoxins when several mycotoxins are present simultaneously because this situation, according to conventional analytical methods, could be declared as quality safe or toxicologically negative finding.
Loughborough University Institutional Repository Manufacturing resilience via inventory management for domestic food waste

The ability to feed 9 billion people by 2050 will rely on processed foods being delivered through complex and dispersed international supply chains. Currently as much as a third of all food grown is lost as waste at various points along existing supply chains, with roughly half of food waste in the developed world occurring after purchase by the end consumer. For the long-term resilience of the food industry, and as holders of critical information, manufacturers need to play a part in reducing this waste. Using a novel method of food waste categorization, this research describes how the prevention of food waste for certain categories can be facilitated using a Smart Phone App that enables industrial inventory management for the domestic environment, providing the consumer with supporting information about food condition and appropriate preparation processes. Data availability issues and the benefits in terms of resource efficiency and consumer loyalty are discussed. © 2016 The Authors. Published by Elsevier B.V.

Estimating PAH Dry Deposition by Measuring Gas and Particle Phase Concentrations in Ambient Air

Concentrations of the total polycyclic aromatic hydrocarbons (PAHs) in both the gas-phase and particle-phase were measured simultaneously in industrial, urban and suburban areas, and were 1652, 1185, and 834 ng/m 3 , respectively. PAHs with two to four-ring were distributed more than 94% in the gas-phase of all sampling sites. Meanwhile, for PAHs with five to seven-ring, less than 70% were distributed in the gas-phase of the three sites. Approximately two-thirds of the three most hazardous PAHs (BbF + BaP + DBA) were distributed in the gas-phase at the TIP and NCHU, and only one-third of BbF + BaP + DBA were distributed in the gas-phase at the THU. Total dry deposition flux was mainly contributed, with a proportion of between 53.3% and 63.4%, by PAHs with three to four-ring at the three sites. For LMW PAHs, the gas-phase PAHs contribute over 87% to the dry deposition flux at the three sites. Meanwhile, the particle-phase PAHs contribute more than 86% and 99% to the dry deposition flux of the MMW and HMW PAHs, respectively. The mean dry deposition velocities were 0.01, 0.24, 0.47, 0.76, 0.84 and 0.88 cm/s for two to seven-ring PAH homologue. Notably, the dry deposition velocity of the HMW PAHs was significantly higher than that of the LMW PAHs at the three sampling sites. The dry deposition velocities of BbF + BaP + DBA PAHs were 0.8, 0.64 and 1.02 cm/s at the TIP, NCHU and THU, respectively. Accordingly, hazardous PAHs with high dry deposition velocities are threatening to human health by dry deposition.
Analytical Estimation of the Electrostatic Field in Cylinder-Plane and Cylinder-Cylinder Electrode Configurations

This work presents analytical formulas for the estimation of the electrostatic field in cylinder-plane and cylinder-cylinder electrode configurations. Assuming a predefined potential difference between the electrodes and given their geometrical characteristics, these could be useful for the solution of numerous problems involving such electrode sets. Moreover, the voltage distribution around the electrodes is defined by providing equations either for the equipotentials at a given voltage ratio, or the exact estimation of the potential at any point in the surrounding space. Simplified expressions for critical engineering parameters such as the peak electric field and the field enhancement factor are also given.
Melt-Processing and Properties of Coaxial Fibers Incorporating Carbon Nanotubes

Polypropylene-multiwalled carbon nanotube (PP-CNT) composites were spun into fibers using melt-spinning methods. The CNT content was varied by diluting the commercial masterbatch with a low viscosity PP homopolymer grade. The conductivity, as well as the mechanical properties, of the fibers were systematically tested in order to find the optimal formulation. Post-stretching was used to improve the mechanical properties of the fibers as well as to decrease the fiber diameters. Fibers having a conductivity of 0.4 S/cm, a Young's modulus of 5.4 GPa and a tensile strength of 250 MPa were obtained after a three-fold stretching. Trilayer coaxial fibers similar to data transfer coaxial cables (two conductive layers separated by an insulating layer) were then produced in a one-step melt-spinning method using a specially designed die, followed by solid state post-stretching.
Improving Search Performance of Tries Data Structures for Network Filtering by Using Cache

Due to the tremendous amount and its rapid increase of network traffic, the performance of network equipments are becoming an important issue. Network filtering is one of primary functions affecting the performance of the network equipment such as a firewall or a load balancer to process the packet. In this paper, we propose a cache based tri method to improve the performance of the existing tri method of searching for network filtering. When several packets are exchanged at a time between a server and a client, the tri method repeats the same search procedure for network filtering. However, the proposed method can avoid unnecessary repetition of search procedure by exploiting cache so that the performance of network filtering can be improved. We performed network filtering experiments for the existing method and the proposed method. Experimental results showed that the proposed method could process more packets up to 790,000 per second than the existing method. When the size of cache list is 11, the proposed method showed the most outstanding performance improvement (18.08%) with respect to memory usage increase (7.75%).
Laparoscopic Cholecystectomy: A Retrospective Audit from The Cayman Islands

Laparoscopic cholecystectomy (LC) brings numerous advantages over open cholecystectomy at the expense of higher complication rates. There have been no prior reports on the outcomes of LC from the Cayman Islands. A three year retrospective audit was performed at the Cayman Islands Hospital in Grand Cayman. Of 110 cholecystectomies, 99 were attempts at LC in 83 females and 16 males. Operations were performed electively in 85% of cases and emergently in 15%. Same day discharge was possible in 19.6% of cases. There were 2 conversions (2.02%) and LC was successfully completed in the remaining 97 patients with an average operating time of 93.74 +/-21.72 minutes (mean +/-SD). Intra-operative cholangiography was performed in 12 elective cases and added 32.09 minutes of operating time. Two patients had laparoscopic bile duct exploration and stone extraction that added 37.67 minutes of operating time. Eight patients experienced morbidity that included bleeding (4), biliary peritonitis (2), visceral injury (1) and pneumonia (1). There was no bile duct injury, wound infection or mortality in this audit. LC is being performed in this setting with acceptable morbidity, mortality and conversion rates. A concerted effort to increase the performance of ambulatory LC may increase cost effectiveness in this setting.

Nonlinear equilibration of a dynamo in a smooth helical flow

We investigate the nonlinear equilibration of magnetic fields in a smooth helical flow at large Reynolds number Re and magnetic Reynolds number Rm with Re[Gt ]Rm[Gt ]1. We start with a smooth spiral Couette flow driven by boundary conditions. Such flows act as dynamos, that is are unstable to growing magnetic fields; here we disregard purely hydrodynamic instabilities such as Taylor–Couette modes. The dominant feedback from a magnetic field mode is only on the mean flow and this yields a simplified ‘mean-flow system’ consisting of one magnetic mode and the mean flow, which we solve numerically. We also obtain the asymptotic structure of the equilibrated fields for weakly and strongly nonlinear regimes. In particular the field tends to concentrate in a cylindrical shell where all stretching and differential rotation is suppressed by the Lorentz force, and the fluid is in solid-body motion. This shell is bounded by thin diffusive layers where the stretching that maintains the field against diffusive decay is dominant.
Radiative effect of surface albedo change from biomass burning

The radiative impact of burn scars from biomass is investigated. Changes in surface albedo derived from satellite observations over the African continent are used as a first order indication of this impact. Because the direct radiative effect of aerosols from biomass burning is dependent on the underlying surface albedo, we investigate the interaction of the direct radiative effect due to biomass burning aerosols with the change in surface reflection due to the burn scars. The radiative effect of reduced surface albedo from burn scars is estimated to be close to 0.1 Wm−2 over a region covering the African continent.
University Students' Behaviors Pertaining to Sustainability: A Structural Equation Model with Sustainability-Related Attributes.

The purpose of this study is to construct a structural equation model to examine the links among attitudes, values, and behaviors pertaining to sustainability, participation in outdoor recreation as well as gender and tendency to follow mass media for university students. The data were collected by on-line administration of a survey to 958 students at Middle East Technical University during February-June of 2008. It needs to be stressed that gender emerged as a strong factor explaining sustainability-related attributes. It was reflected that female students having higher tendency to follow media held more favorable attitudes and behaviors toward sustainable life styles, and more ecocentric values. Furthermore, attitudes and values were found to be significant determinants of university students’ behaviors pertaining to sustainability. It was also reported that higher tendency to follow media yielded more favorable attitudes, higher levels of ecocentric values, and engagement in outdoor recreational activities such as walking in nature, bird watching, and camping. These results implied that the university campus should be well equipped with the necessary infrastructures that will satisfy the needs and encourage female students as well as male students to motivate them take appreciative outdoor activities. A gender perspective should be integrated into existing mainstream institutions and all programmatic areas or sectors, including education in order to hinder gender inequality. In addition, during the rehabilitation of sustainability issues in higher education institutions, favorable attitudes and values of university students should be regarded as an auxiliary agent.
Strategic Interactions and Contagion Effects Under Monetary Unions

This paper applies game theory and a cost‐benefit analysis to study voluntary exits and contagion effects in countries joined to a monetary union. The paper looks at two non‐core or periphery countries of a large union and examines the role of structural asymmetries and strategic interactions as determinants of equilibrium outcomes, following both country‐specific and common shocks. The paper finds that under almost symmetry between countries, country‐specific shocks are never associated with multiple equilibria and, if large enough, can spread to other countries leading to contagion. By contrast, common shocks are seen to sustain multiple equilibria if almost‐symmetric countries are considered and to have implications similar to those found in the country‐specific case if large structural asymmetries are admitted.
Functions of bounded higher variation

We say that a function u: R m → R n , with m ≥ n, has bounded n-variation if Det(u xα1 ,.,u xαn ) is a measure for every 1 ≤ α 1 <. < α n ≤ m. Here Det(ν 1, .,ν n ) denotes the distributional determinant of the matrix whose columns are the given vectors, arranged in the given order. In this paper we establish a number of properties of BnV functions and related functions. We establish general (and rather weak) versions of the chain rule and the coarea formula; we show that stronger forms of the chain rule can fail, and we also demonstrate that BnV functions cannot, in general, be strongly approximated by smooth functions; and we prove that if u ∈ BnV(R m ,R n ) and |u| = 1 a.e. , then the Jacobian of u is an m - n-dimensional rectifiable current.
