title: BlockCopy-based operators for evolving efficient wind farm layouts

authors: Mayo, Michael

subjects: computer science

abstract: A novel search operator, BlockCopy, is proposed for efficiently solving the wind farm layout optimisation problem. BlockCopy, which can be used either as mutation or a crossover operator, copies patterns of turbines from part of a layout to another part. The target layout may be the same as the source, or a different layout altogether. The rationale behind this is that it is the relative configurations of turbines rather than their individual absolute positions on the layouts that count, and BlockCopy, for the most part, maintains relative configurations. Our evaluation on four benchmark scenarios shows that BlockCopy outperforms two other standard approaches (namely, the turbine displacement algorithm and random perturbation) from the literature. We also evaluate the BlockCopy operator in conjunction with both singlesolution and population-based strategies.

title: La prise de Cayenne en 1664 : une nouvelle perspective

authors: Jennings, William

subjects: Cayenne, Guyane, Colbert, Compagnie française des Indes Occidentales, Palikur

abstract: Résumé La conquête de Cayenne en 1664 marque les prémisses de la politique coloniale de Louis XIV. L’événement est pourtant mal connu, faute de sources primaires fiables, cependant le témoignage inédit du notaire de l’expédition décrit le voyage à Cayenne, la reddition de la colonie hollandaise ainsi les relations entre la marine royale et la compagnie coloniale privée à l’origine de la Compagnie française des Indes Occidentales. Il donne aussi un bref aperçu des habitants indigènes de la Guyane. Mots clé : Cayenne, Guyane, Colbert, Compagnie française des Indes Occidentales, Palikur

title: Cultural tattoos: meanings, descriptors, and attributions

authors: Nikora, Linda Waimarie

subjects: Maori

abstract: Body piercing and tattoo/ta moko were initially seen to be practiced by sailors,
criminals, specific cultural groups (e.g., Māori), or sub-cultural groups (e.g., bikers,
gang members, adolescents). In recent times, these practices have become part of
mainstream popular culture, and are enjoyed by a wide range of people. In this
study, we set out to explore patterns of body modifying behaviour engaged in, or
commented on, by a sample of university students. We invited undergraduate
psychology students from two courses to complete an ‘online’ questionnaire.
Students logged on to a web site, were presented with an information sheet, and
invited to respond. In this paper, we present the reasons why people in this sample
decided to obtain a tattoo and the meanings they ascribe to their modifications. We
will also consider the observations that people make of those who have culturally
inspired tattoos.
