Chaotic image encryption using hopfield and hindmarsh–rose neurons implemented on FPGA

Chaotic systems implemented by artificial neural networks are good candidates for data encryption. In this manner, this paper introduces the cryptographic application of the Hopfield and the Hindmarsh–Rose neurons. The contribution is focused on finding suitable coefficient values of the neurons to generate robust random binary sequences that can be used in image encryption. This task is performed by evaluating the bifurcation diagrams from which one chooses appropriate coefficient values of the mathematical models that produce high positive Lyapunov exponent and Kaplan–Yorke dimension values, which are computed using TISEAN. The randomness of both the Hopfield and the Hindmarsh–Rose neurons is evaluated from chaotic time series data by performing National Institute of Standard and Technology (NIST) tests. The implementation of both neurons is done using field-programmable gate arrays whose architectures are used to develop an encryption system for RGB images. The success of the encryption system is confirmed by performing correlation, histogram, variance, entropy, and Number of Pixel Change Rate (NPCR) tests

"Look What the Bride Has Got On!": A Visual Discourse Analysis of Uganda's Wedding Industry

Uganda's leading newspaper, New Vision, showcases images of men and women dressed in crisp tuxedos and white wedding dresses proclaiming their "eternal love" for one another alongside advice columns on how to create the perfect wedding. Exploring images of the wedding industry in Uganda has important political implications through which one can analyze the ways that conceptions of femininity and gender are constructed and perpetuated within the space of the newspaper. Due to Uganda's neoliberal reforms of the past thirty years, a growing middle class has emerged along with an increase in the consumption of luxury goods and services. The white wedding has been and is increasingly a space for middle class Ugandans to highlight their wealth through luxurious venues, extravagant cakes, and designer dresses and tuxedos. As such, it is intimately tied to neoliberal shifts and a state-sponsored quest for capitalist growth. My research focuses on images of the Ugandan wedding industry, including advertisements and advice columns in New Vision, storefronts, fashion shows, and the Bride & Groom Expo in Kampala. Drawing on Rose (2001), I conduct a visual discourse analysis on these images to analyze what and who appears in these images, how the subjects of the images are positioned/represented, and what is absent from the images. Furthermore, I ask what the form and nature of this growing industry is and what ideals of race, class, gender and sexuality are embodied in the bodies of featured brides.Geography and the Environmen

Lifestyle understanding through the analysis of egocentric photo-streams

At 8:15, before going to work, Rose puts on her pullover and attaches to it the small portable camera that looks like a hanger. The camera will take two images per minute throughout the day and will record almost everything Rose experiences: the people she meets, how long she sits in front of her computer, what she eats, where she goes, etc. These images show an objective description of Rose's experiences. This thesis addresses the development of automatic computer vision tools for the study of people's behaviours. To this end, we rely on the analysis of the visual data offered by these collected sequences of images by wearable cameras. Our developed models have demonstrated to be a powerful tool for the extraction of information about the behaviours of people in society. Examples of applications: 1) selected images as cues to trigger autobiographical memory about past events for prevention of cognitive and functional decline and memory enhancement in elderly people. 2) Self-monitoring devices as people want to increase their self-knowledge through quantitative analysis, expecting that it will lead to psychological well-being and the improvement of their lifestyle. 3) businesses are already making use of such data regarding information about their employees and clients, in order to improve productivity, well-being and customer satisfaction. The ultimate goal is to help people like Rose to improve the quality of our life by creating awareness about our habits and life balance

Ravishing: The Rose in Fashion

An exploration of how the rose—the most ravishingly beautiful and symbolic of flowers—has inspired fashion over hundreds of years. The Rose in Fashion: Ravishing is a fascinating exploration of how the rose has inspired the way we look, dress, feel, and fantasize. It foregrounds innovative, refined, and challenging fashion design from elite 18th-century woven silks to the latest gender-neutral catwalk trends and Alexander McQueen rose dresses. Drawing upon fashion clothing, everyday dress, millinery, fine jewelry, perfume, and artificial and fresh roses, multiple expert contributors make reference to love, beauty, sex, sin, gendered identities, rites of passage, transgression, degradation, and death. This sumptuously illustrated book also includes a contribution and stunning images of roses by visionary photographer Nick Knight. Wild yet cultivated, savage yet delicate, this flower has remained an enduring symbol perhaps due to its versatility and the dichotomies it represents.

Mroczne żądło zdegenerowanej natury. Szkic o czarnoromantycznych inspiracjach Róży Wojciecha Smarzowskiego

The dark sting of degenerate nature. Sketch of the dark-romantic inspirationsin Wojciech Smarzowski’s RoseThe text presents Polish dark romanticism as an important source of inspiration for the images of violence, includ- ing sexual violence, in Wojciech Smarzowskis Rose. The author reveals the mechanisms of this inspiration: visual, dramatic, intellectual, and refers to specific literary texts, from the Romantic era and later, by Antoni Malczewski, Seweryn Goszczyński, Juliusz Słowacki and Włodzimierz Odojewski.The dark sting of degenerate nature.

The Ribbon and the Rose : Visual Rhetorics Against Violence to Women

After the December 6, 1989 massacre of fourteen young women at Montréal’s École Polytechnique, Canadian women’s anti-violence groups and a now international men’s campaign against men’s violence to women adopted a variety of resonant visual images in commemoration and protest. The striking differences underlying women’s and men’s choices of images also reflect tensions at a rhetorical level about the appropriateness of men speaking out against violence to women. To explore these tensions, this article uses a method of rhetorical analysis that maps associations among “men’s” and “women’s” images, situates these associations within particular social contexts, and suggests some possible effects of these images and their messages on various audiences. While some activists feared that the men’s white ribbon — rather than the women’s rose or other symbols — might dominate the public imagination as a generalized protest against violence to women, a brief joint billboard campaign displaying the white ribbon and the rose side by side represents the possibility of women and men working with and through the power inequalities that exacerbate gender differences.Après le massacre, le 6 décembre 1989, de quatorze jeunes femmes à l’École polytechnique de Montréal, des groupes anti-violence de femmes canadiennes et une campagne, à présent internationale, d’hommes contre la violence faite aux femmes par les hommes, ont adopté un certain nombre de signes visuels (qui se remarquent) en signe de commémoration et de protestation. Les différences frappantes, sous-jacentes aux choix des hommes et des femmes, reflètent, au niveau discursif, les tensions concernant la question de savoir s’il était convenable ou à-propos que des hommes protestent contre la violence faite aux femmes. Pour explorer ces tensions, cet article utilise une méthode d’analyse rhétorique qui «ESPINSECcartographieESPINSEC» les associations entre les images des femmes et les images des hommes, situe ces associations à l’intérieur de leurs contextes particuliers et suggère quelques effets possibles de ces images et de leurs messages sur des publics variés. Tandis que certaines activistes redoutaient que le ruban blanc des hommes — plutôt que la rose des femmes ou d’autres symboles — ne domine l’imagination publique en tant que protestation généralisée contre la violence faite aux femmes, une brève campagne conjointe montrant côte à côte le ruban blanc et la rose a représenté pour les hommes et les femmes la possibilité de travailler sur et à travers les inégalités qui exacerbent les différences de genre
