    Two segmented gold copper nanowires were grown inside the pores of polycarbonate track (PCT) etched membranes from two separate solutions by electrodeposition method. Optical absorption spectra of two segmented Au Cu nanowires in PCT template were shown a surface plasmon- polariton peak appeared at about 900 nm for incident angle of theta = 65 degrees but for theta= 0 there are not any peaks in spectra

    An e-learning system in the risk assessment engineering domain has been developed by a consortium led by Ligeron® in the context of the Vicaria project (Leonado da Vinci – N° PP 118018). The e-learning platform: www.vicaria.fr has been implemented and hosted by OVH in compliance with SCORM (Shareable Content Object Reference Model) standard. The Vicaria modules contents have been defined according to an investigation performed in different European countries, particularly in France, to gather the user requirements. The Vicaria contents dedicated mainly to the environmental risks and ICPE are now available for use in French. The issue of the performed work and the e-learning system specifics are partly summarized in this pape

    Influence Of Media Viewing Habits On Attitude Towards Aggression Among Schoolboys At International Schools In Kuala Lumpur.

    Violence is one of the global concerns today in all segments of the world. Antisocial behavior in human beings is accepted to be associated to a number of physiological, psychological, domestic, and cultural aspects. The learning environments which a child is exposed are also assumed to contribute to the increase of aggressive behavior and attitudes. Media violence as one of specific learning condition is believed to be a potential contributor to the growth of antisocial behavior in children and youth. Many studies have been conducted in the area of media violence and its effects on the young viewers. A major focus has been the relationship between media violence and aggressive behavior but, interestingly, research regarding the relationship between media violence and attitudes about aggression is limited. The purpose of this study, therefore, was to contribute to the state of the research by predicting and comparing attitudes about aggression among adolescent boys on the basis of their exposure to violence in movies

    Cooperative Lattice Coding and Decoding

    Full text link
    A novel lattice coding framework is proposed for outage-limited cooperative channels. This framework provides practical implementations for the optimal cooperation protocols proposed by Azarian et al. In particular, for the relay channel we implement a variant of the dynamic decode and forward protocol, which uses orthogonal constellations to reduce the channel seen by the destination to a single-input single-output time-selective one, while inheriting the same diversity-multiplexing tradeoff. This simplification allows for building the receiver using traditional belief propagation or tree search architectures. Our framework also generalizes the coding scheme of Yang and Belfiore in the context of amplify and forward cooperation. For the cooperative multiple access channel, a tree coding approach, matched to the optimal linear cooperation protocol of Azarain et al, is developed. For this scenario, the MMSE-DFE Fano decoder is shown to enjoy an excellent tradeoff between performance and complexity. Finally, the utility of the proposed schemes is established via a comprehensive simulation study.Comment: 25 pages, 8 figure
