Réponses vibratoires non-linéaires dans un contexte industriel : essais et simulations

Ces travaux de these portent sur l’etude experimentale et numerique des reponses vibratoires non lineaires des structures mecaniques. Les etudes experimentales menees au CEA/CESTA montrent que la reponse des structures assemblees a des sollicitations vibratoires est souvent tres fortement dependante du niveau d’excitation. Ces resultats experimentaux ne peuvent pas etre reproduits en simulation avec la methode de simulation vibratoire lineaire classique. L’objectif de ces travaux est de proposer et de mettre en place des methodes experimentales et numeriques pour etudier ces reponses non-lineaires. Cet objectif passe par l’etude de maquettes d’essai sujettes aux memes phenomenes vibratoires non-lineaire que les objets d’etude industriels du CEA/CESTA. Au niveau experimental, les developpements se basent sur les installations et logiciels industriels. Au niveau simulation, les methodes de simulation vibratoire non-lineaires et les techniques numeriques avancees developpees depuis de nombreuses annees dans le monde academique sont utilisees dans le contexte industriel du CEA/CESTA. Le premier objet d’etude est une poutre metallique bi-encastree. Cette structure presente une reponse vibratoire non-lineaire d’origine geometrique. La structure est modelisee avec des conditions aux limites non-ideales et sa reponse vibratoire est simulee par trois methodes (developpement multi- echelles, methode de balance harmonique et methode de tir). Ces resultats de simulation sont compares entre eux et avec l’experience. La maquette d’etude au cœur de ces travaux de these est un assemblage presentant des interfaces frottantes : la maquette ✭✭Harmonie ✮✮. De nombreux essais vibratoires sont realises sur cette maquette afin d’identifier ses modes de resonance et ceux de ses composants, d’etudier l’evolution de la reponse vibratoire de l’assemblage due au frottement et enfin de mesurer le mouvement vibratoire local dans la zone de frottement. Un modele numerique de cette structure est ensuite realise. Ce modele est reduit par une methode de sous-structuration puis des relations non-lineaires de frottement sont introduites au niveau des liaisons frottantes. La reponse vibratoire non-lineaire du modele obtenu est simulee grâce a la methode de balance harmonique couplee a des algorithmes de condensation et de continuation. Des comparaisons essai-calcul sont presentees pour les reponses globales et pour les mouvements locaux des liaisons.
Human support system using haptic cell

Recently, doctor and medical care persons are shortage by the aging of population. Thus, robot support systems are needed for medical care. The motion of the human support system is controlled by routine. Position control and velocity control is usual method. These controls are not considered the human motion. This paper proposes method of human support system using motion coping system. The motion coping system saves human motion information. The proposed method supports the human based on saved human motion information. Effectiveness of the proposed method is verified by experimental results.
Diode-Pumped Passively Q-Switched ${\rm Nd}{:}({\rm Lu}_{0.1}{\rm Gd}_{0.9})_{3}{\rm Ga}_{5}{\rm O}_{12}$ Laser at 1330 nm With ${\rm V}^{3+}{:}{\rm YAG}$ as Saturable Absorber

The performance of a diode-end-pumped cont- inuous wave (CW) and passively Q-switched Nd:(Lu<sub>0.1</sub>Gd<sub>0.9</sub>)<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> (Nd:LGGG) laser at 1330 nm were realized for the first time. The maximum CW output power of 0.93 W was obtained under the absorbed pump power of 11 W, corresponding to the slope efficiency of 10.4. By using V<sup>3+</sup>:YAG crystal as an absorber for passively Q-switching operation, the maximum average output power of 167 mW was generated with the minimum pulsewidth of 15.6 ns and the maximum repetition rate of 10 kHz. The corresponding signal pulse energy and pulse peak power were calculated to be 16.7 μJ and 1.1 kW, respectively.
Target-dependent Sentiment Analysis of Tweets using a Bi-directional Gated Recurrent Unit

Targeted sentiment analysis classifies the sentiment polarity towards a certain target in a given text. In this paper, we propose a target-dependent bidirectional gated recurrent unit (TD-biGRU) for target-dependent sentiment analysis of tweets. The proposed model has the ability to represent the interaction between the targets and their contexts. We have evaluated the effectiveness of the proposed model on a benchmark dataset from Twitter. The experiments show that our proposed model outperforms the state-of-the-are methods for target-dependent sentiment analysis.
FISH OF THE AMAZON : FROM MOLECULAR TO BEHAVIORAL ASPECTS

Fish adaptation to hypoxia does not include, necessarily, the ability to tolerate hypoxia; however, it does include mechanisms they use to avoid hypoxia. Literature reviews on fish of the Amazon shows that they search for oxygen rich environments trying to reach air, water surface layer, or aquatic plant roots when facing hypoxia. While the oxygen lack is considered one of the main causes of air-breathing appearance among fish, the ability to breathe air is not necessarily related to the development of hypoxia tolerance. Additionally, some non airbreathing fish groups do tolerate hypoxia and are able to remain in hypoxic and anoxic environments. This paper will review the main adaptive mechanisms fish developed to survive hypoxic environments and try to correlate changes in innate behavior, morphology and anatomy with physiological and biochemical adaptive mechanisms under an evolutionary perspective. Considering that evolution of hypoxia tolerance is related to genetic mechanisms, we will discuss the studies of genes considered to be involved with hypoxia adaptation: LDH A*, B*, and C*. Data on LDH cDNA seem to be consistent with functional aspects of this isozyme system. Considering that the evolution of hypoxia tolerance in fish may have induced the whole group to adaptive radiation, we suggest it may have contributed to the biological fish diversity in the Amazon basin.
Phylogenetic group‐associated differences in regulation of the common colonization factor Mat fimbria in Escherichia coli

Heterogeneity of cell population is a key component behind the evolutionary success of Escherichia coli. The heterogeneity supports species adaptation and mainly results from lateral gene transfer. Adaptation may also involve genomic alterations that affect regulation of conserved genes. Here we analysed regulation of the mat (or ecp) genes that encode a conserved fimbrial adhesin of E. coli. We found that the differential and temperature‐sensitive expression control of the mat operon is dependent on mat promoter polymorphism and closely linked to phylogenetic grouping of E. coli. In the mat promoter lineage favouring fimbriae expression, the mat operon‐encoded regulator MatA forms a positive feedback loop that overcomes the repression by H‐NS and stabilizes the fimbrillin mRNA under low growth temperature, acidic pH or elevated levels of acetate. The study exemplifies phylogenetic group‐associated expression of a highly common surface organelle in E. coli.
Empirical Fuzzy Sets

In this paper, we introduce a new form of describing fuzzy sets (FSs) and a new form of fuzzy rule‐based (FRB) systems, namely, empirical fuzzy sets (εFSs) and empirical fuzzy rule‐based (εFRB) systems. Traditionally, the membership functions (MFs), which are the key mathematical representation of FSs, are designed subjectively or extracted from the data by clustering projections or defined subjectively. εFSs, on the contrary, are described by the empirically derived membership functions (εMFs). The new proposal made in this paper is based on the recently introduced Empirical Data Analytics (EDA) computational framework and is closely linked with the density of the data. This allows to keep and improve the link between the objective data and the subjective labels, linguistic terms, and classes definition. Furthermore, εFSs can deal with heterogeneous data combining categorical with continuous and/or discrete data in a natural way. εFRB systems can be extracted from data including data streams and can have dynamically evolving structure. However, they can also be used as a tool to represent expert knowledge. The main difference from the traditional FSs and FRB systems is that the expert does not need to define the MF per variable; instead, possibly multimodal, densities will be extracted automatically from the data and used as εMFs in a vector form for all numerical variables. This is done in a seamless way whereby the human involvement is only required to label the classes and linguistic terms. Moreover, even this intervention is optional. Thus, the proposed new approach to define and design the FSs and FRB systems puts the human “in the driving seat. ” Instead of asking experts to define features and MFs correspondingly, to parameterize them, to define algorithm parameters, to choose types of MFs, or to label each individual item, it only requires (optionally) to select prototypes from data and (again, optionally) to label them. Numerical examples as well as a naïve empirical fuzzy (εF) classifier are presented with an illustrative purpose. Due to the very fundamental nature of the proposal, it can have a very wide area of applications resulting in a series of new algorithms such as εF classifiers, εF predictors, εF controllers, and so on. This is left for the future research.

The Sequence of a 8 kb Segment on the Right Arm of Yeast Chromosome VII Identifies Four New Open Reading Frames and the Gene For yTAFII145

We report the sequence of a 8061 bp fragment of Saccharomyces cerevisiae chromosome VII. Five open reading frames (ORFs) of at least 100 amino acids were identified. Three show similarities to the amino‐acid sequence of known gene products. ORF G9374 corresponds to the gene coding for the yTAFII145 protein: a TBP‐associated factor whose amino‐acid sequence was previously reported (Reese et al., 1994). The remaining ORF does not display similarities to known sequences. The complete nucleotide sequence was submitted to the EMBL database (Accession Number X84098). © 1997 John Wiley & Sons, Ltd.
Microbial production of phase I and phase II metabolites of propranolol

The production in multimilligram amounts of 4- and 5-hydroxylated metabolites of (R)- or (S)-propranolol by biotransformation with two fungal strains, an Absidia sp. M50002 and a Cunninghamella sp. M50036, was carried out, starting from either the racemic drug or pure enantiomers. While both enantiomers of propranolol were hydroxylated in the 5-position by incubation with strain M50002, the strain M50036 operated a chiral discrimination, resulting in the exclusive formation of the 4-hydroxy-(R)-enantiomer. In addition, a Streptomyces sp. strain M52104, isolated from a soil sample, was selected for the high-yield regioselective β-glucuronidation of propranolol and its 4- and 5-hydroxylated derivatives. NMR and mass spectroscopic data have been extensively used for the unambiguous characterization of 4- and 5-hydroxylated and glucuronidated derivatives, all of them corresponding to the major animal and human metabolites of propranolol, a typical substrate of CYP2D6.
Interrelations of codes in human semiotic systems

Abstract Codes can be viewed as mechanisms that enable relations of signs and their components, i.e., semiosis is actualized. The combinations of these relations produce new relations as new codes are building over other codes. Structures appear in the mechanisms of codes. Hence, codes can be described as transformations of structures from some material systems into others. Structures belong to different carriers, but exist in codes in their “pure” form. Building of codes over other codes fosters their regulation. There are several ways to add codes: by types of transformation of structures involved in codes; by dimensions of pragmatics, semantics, and syntactics; through “abstract universals versus precise forms” relations; and by regulation levels in the “organism – environment” relations. More complicated codes are formed based on the interrelations of codes built over. These interrelations are presented as a conceptual chart, which reflects the way typical semiotic formations emerge in mind based on the interrelations of various codes. It also presents the related sociocultural semiotic systemities: motives, needs, aspirations, moral values, purposes, language-like systemities, fundamental frames, patterns of culture, etc.
Accurate Delay Metric for On-chip Resistive Interconnect

This paper presents a delay metric for resistive interconnect which computes the delay to any point on the waveform at any point along the interconnect. It is based on the first two moments of the impulse response. The empirical D2M metric [I] is shown to be a special case of the one presented here. The metric has proven to be accurate to within 5% of HSPICE simulations.
VGI in surveying engineering: Introducing collaborative cloud land surveying

: Volunteered geographic information (VGI) has enabled many innovative applications in various scientiﬁc ﬁelds. This paper introduces a new framework called “collabora-tive cloud-based land surveying” (CCLS) that uses VGI principles for data sharing among surveyor engineers to boost the productivity and improve the quality of their applications. A cloud-based spatio-temporal data repository is presented, aiming to facilitate the sharing of VGI among surveyor engineers. A fully-functional distributed software application has been developed and used to apply CCLS in a large-scale land surveying project run by the Greek Ministry of Culture, which involves the mapping of the historic center of Athens. Results from the data analysis of hundreds of measurements indicate a substantial (30% to 60%) error reduction and also a signiﬁcant productivity raise ( ∼ 22%). The collected measurements are shared in an online database, accessible by professional surveyors who can in turn contribute their own data to further enhance the CCLS system.
Measuring Perceptions of Trustworthiness: A Research Project

The digital curation and preservation community has long acknowledged that trustworthiness is a critical component of successful digital repositories. However, there is no known method to determine if or under what circumstances an end-user perceives a repository as trustworthy. While the research literature describes definitions, criteria, and certification processes that allow repository managers to assert trustworthiness under certain conditions, it does not adequately define, measure, or specify trustworthiness from the perspective of the end-user. This paper highlights traditional notions of trustworthiness in the context of the literature on digital repositories and explores trustworthiness from the end-user’s perspective. The paper also presents an ongoing research project to: (1) investigate designated communities’ perspectives on trustworthiness using focus groups, and (2) explore building, testing, and assessing an index to measure trustworthiness.
Human Herpesvirus 8 Seroprevalence and Evaluation of Nonsexual Transmission Routes by Detection of DNA in Clinical Specimens from Human Immunodeficiency Virus-Seronegative Patients from Central and Southern Italy, with and without Kaposi’s Sarcoma

ABSTRACT In order to investigate the seroprevalence of human herpesvirus 8 (HHV-8) infection in central and southern Italy, sera from human immunodeficiency virus (HIV)-seronegative subjects, with and without Kaposi’s sarcoma (KS), were analyzed by immunofluorescence assay, using BC-3, a cell line latently infected with HHV-8. High titers of antibody against HHV-8 lytic and latent antigens were detected in all 50 KS patients studied, while in 50 HIV-seronegative subjects without KS, 32 (64%) were found positive for HHV-8 antibodies. Titers in the sera of these patients were lower than those for KS patients. This data suggests that HHV-8 infection is not restricted to KS patients and that the prevalence of HHV-8 infection in the general population may be correlated with differing rates of prevalence of KS in different parts of the world. In view of these findings, possible nonsexual transmission routes were evaluated. Nested PCR was used to test for the presence of HHV-8 DNA in saliva, urine, and tonsillar swabs from KS and non-KS patients. In KS patients, 14 out of 32 tonsillar swabs (43.7%), 11 out of 24 saliva samples (45.8%), and just 2 out of 24 urine samples (8.3%) tested positive for HHV-8 DNA. In the control group, on the contrary, none of the 20 saliva and 20 urine specimens was positive for HHV-8 DNA; only 1 out of 22 tonsillar swabs gave a positive result. This data supports the hypothesis that HHV-8 infects the general population in a latent form. The reactivation of viral infection may result in salivary shedding of HHV-8, contributing to viral spread by nonsexual transmission routes.
Simulation of Surface Plasmon Coupled Conjugate Polymer for Polymer Light-Emitting Diodes

Since 1977, conjugated polymers have received attention as materials for display devices with a low-cost solution process, but the low efficiency of these materials has been considered as a drawback which should be overcome. Nowadays metal nanoparticles are inserted on the display device's cathode to overcome the low efficiency of the materials through the enhanced coupling between the Localized surface plasmon resonance (LSPR) and exciton in emitting material . In our previous work, conjugated polymer with an imprinted regular Ag-dot-array structure showed a 2.7-fold improvement of integrated photoluminescence (PL) intensity , but the result was not optimized. Therefore, in this study, we calculated the Ag-dot-array absorbance-peak shift in detail using finite-difference time-domain (FDTD) simulation and found the absorbance peak location which maximized photoluminescence (PL) intensity, depending on various Ag dot condition. The resulting information was applied to the previous structure . Thus, we reduced the trial and error of finding the optimized absorbance peak location and the imprint processing costs. The most important parameter of the Ag-dot-array absorbance peak was the lattice constant. Furthermore, we proved the indium tin oxide (ITO) waveguide effect in our structure using FDTD.
Framework of Frequently Trajectory Extraction from AIS Data

Mining trajectory data has been attracting significant interest in the last years. Emerging technologies like Automatic Identification System (AIS) provides multi-dimensional data which is about voyages and vessels. The maritime area is a free moving space. Unlike the vehicles’ movements are constrained by road networks, there is no such a sea route for ships to follow in maritime area. In this Paper, we propose a framework of frequently voyage extraction from AIS data, which learns frequently voyages using improved dynamic time warping(IDTW) an Adaptive Density Increment Clustering (ADIC). ADIC can adaptively adjust parameters on uneven density data . We conduct the experiments on real maritime trajectories to show the effectiveness of proposed framework.
Monte Carlo simulations of new 2D ripple filters for particle therapy facilities

Abstract At particle therapy facilities with pencil beam scanning, the implementation of a ripple filter (RiFi) broadens the Bragg peak (BP), which leads to fewer energy steps from the accelerator required to obtain an homogeneous dose coverage of the planned target volume (PTV). At the Universitätsklinikum Gießen und Marburg, Germany, a new second generation RiFi has been developed with two-dimensional groove structures. In this work we evaluate this new RiFi design. Methods: The Monte Carlo (MC) code SHIELD-HIT12A is used to determine the RiFi-induced inhomogeneities in the dose distribution for various ion types, initial particle energies and distances from the RiFi to the phantom surface as well as in the depth of the phantom. The beam delivery and monitor system (BAMS) used at Marburg, the Heidelberg Ionentherapiezentrum (HIT), Universitätsklinikum Heidelberg, Germany and the GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany is modeled and simulated. To evaluate the PTV dose coverage performance of the new RiFi design, the heavy ion treatment planning system TRiP98 is used for dose optimization. SHIELD-HIT12A is used to prepare the facility-specific physical dose kernels needed by TRiP, and for recalculating the physical dose distribution after TRiP optimization. Results: At short distances from the RiFi to the phantom surface fine structures in the dose distribution are observed. For various RiFis, ion types and initial particle energies the distance dmax at which maximum dose inhomogeneity occurs is found and an expression for dmax is deduced. The distance d0.01 at which the dose inhomogeneity is less than 1% is estimated and used as a threshold distance at which dose distributions are considered homogeneous. The MC data are found to agree with analytical expressions for dmax and d0.01; both are inversely related to the angular distribution. Increasing scatter from the beam delivery and monitoring system results in reduced dmax and d0.01. Furthermore, dmax and d0.01 are found to be proportional to the RiFi period λ. Conclusion: Our findings clearly indicate that the dose inhomogeneity induced by RiFis does not add uncertainties to the dose distribution in the clinical setting. The new RiFi design can be used in treatments to obtain homogeneous PTV dose coverage with fewer energy steps while improving lateral penumbra, thereby reducing the required treatment time.
Practice and guidelines.

As a former practicing pediatrician turned academic, I found the article entitled "The Management of Febrile Infants by Primary-Care Pediatricians in Utah: Comparison with Published Practice Guidelines"1 interesting if not disturbing. Three case scenarios were sent to 194 pediatricians: a 3-week-old infant with fever, a 2-month-old infant with rales and bilateral otitis media, and a 20-month-old infant with fever. Ninety-four pediatricians responded and their workups and approaches to treatment compared to ‘practice guidelines" developed by Baraff et al.2
Applications and Ground Cover Ratio

Energy yield and occupation of land are two parameters that must be optimized when designing a large PV plant. This paper presents the results of simulating the energy yield of flat panels for some locations and different tracking strategies as a function of the ground cover ratio. Some interesting results for design purposes, such as the optimal solar trackers depending on the land availability or the energy gains of every tracking strategy, are shown. For example, the energy gains associated to one north–south axis tracking, referenced to static surfaces, ranges from 18 to 25%, and from 37 to 45% for the two-axes tracker for reasonable ground cover ratios. To achieve these results, a simulation tool with appropriate models to calculate the energy yield for different solar trackers has been developed. Copyright # 2008 John Wiley & Sons, Ltd.
