Pentagon-Based Radial Tiling with Triangles and Rectangles and Its Spatial Interpretation

The paper considers a type of radial pentagon-based tiling consisting of two shapes: triangle and rectangle. The ob tained solution has a spatial interpretation in a 3D arrangement of equilateral triangles and squares dictated by the particular array of concave cupolae of the second sort, minor type (CC-II 5.m). These cupolae are arranged so that their decagonal bases partly overlap, making a pentagonal pattern (similar to the one of the Penrose tiling). Covering the folds between the faces of such a polyhedral structure with polygons, we use exactly equi lateral triangles and squares, thanks to the trigonometric prop erties of CC-II-5.m. Observed in the orthogonal projection onto the plane of the polygonal bases, this 3D “covering” is viewed as a pentagonal-based radial tiling in the Euclidean plane. Equilateral triangles will be projected into congruent isosceles triangles corresponding to those obtained by the radial sec tion of a regular pentagon in 5 parts. The squares are project ed into rectangles whose ratio is: a:b = 1:φ/√(1+φ2), where φ is the golden ratio. These triangles and rectangles form a ra dial tiling consisting of 5 sectors of the plane, where the pat terns of the established tiles are repeated locally periodically. However, with 5-fold rotation of the pattern, the tiling itself is non-periodic. The various tiling solutions that can be obtained in this way may serve as inspiration for the geometric design, especially interesting in architecture and applied arts, e.g. for rosettes, brise soleils, mosaics, stained glass, fences, partition screens and the likehttps://smartart-conference.rs/sr/%d1%82%d0%b5%d0%bc%d0%b0%d1%82%d1%81%d0%ba%d0%b8-%d0%b7%d0%b1%d0%be%d1%80%d0%bd%d0%b8%d0%ba-2021/ http://doi.fil.bg.ac.rs/pdf/eb_ser/smartart/2022-2/smartart-2022-2-ch19.pd

Design and semantics of form and movement (DeSForM 2006)

Design and Semantics of Form and Movement (DeSForM) grew from applied research exploring emerging design methods and practices to support new generation product and interface design. The products and interfaces are concerned with: the context of ubiquitous computing and ambient technologies and the need for greater empathy in the pre-programmed behaviour of the ‘machines’ that populate our lives. Such explorative research in the CfDR has been led by Young, supported by Kyffin, Visiting Professor from Philips Design and sponsored by Philips Design over a period of four years (research funding £87k). DeSForM1 was the first of a series of three conferences that enable the presentation and debate of international work within this field: • 1st European conference on Design and Semantics of Form and Movement (DeSForM1), Baltic, Gateshead, 2005, Feijs L., Kyffin S. & Young R.A. eds. • 2nd European conference on Design and Semantics of Form and Movement (DeSForM2), Evoluon, Eindhoven, 2006, Feijs L., Kyffin S. & Young R.A. eds. • 3rd European conference on Design and Semantics of Form and Movement (DeSForM3), New Design School Building, Newcastle, 2007, Feijs L., Kyffin S. & Young R.A. eds. Philips sponsorship of practice-based enquiry led to research by three teams of research students over three years and on-going sponsorship of research through the Northumbria University Design and Innovation Laboratory (nuDIL). Young has been invited on the steering panel of the UK Thinking Digital Conference concerning the latest developments in digital and media technologies. Informed by this research is the work of PhD student Yukie Nakano who examines new technologies in relation to eco-design textiles

“Why not pitch the whole enterprise at the highest level possible?”: Speculative Radicalism and the Planetary Topics

This dissertation problematizes the hegemony of “critique” within the humanities in general and communication studies in particular. I argue that critique in the current mode, a reading and engagement practice that valorizes suspicion and purports to unmask allegedly concealed ideologies, does not equip scholars or students with the imaginative capacity necessary to confront the problems of the Anthropocene. Drawing upon the resources of speculative realism and speculative fiction, I propose speculative radicalism as an alternative practice. Speculative radicalism is an affirmative mode of reading, engagement, and theorizing that encourages the imagining of alternative future ways of living and modes of production, proceeding stepwise from a posited point of difference, or “novum.” Kim Stanley Robinson’s Mars Trilogy is offered as a model of invention in the speculative radicalist mode. With the goal of elaborating how speculative radicalism operates in this context, I repurpose the rhetorical topics of invention, or topoi. I argue that to fully appreciate the Mars Trilogy, one must understand that its applicable topics are, in fact, the planetary features of Mars itself: its gravity, landforms, and more. I develop and analyze this list of the planetary topics in the context of the Trilogy. In addition, I use the planetary topics to reevaluate established critical readings of the strategy video game series Sid Meier’s Civilization, as well as Robert Zubrin’s nonfiction space advocacy monograph The Case for Mars. I conclude that a reading of these artifacts informed by the planetary topics can yield more nuanced judgements than those produced by the prevailing style of academic critique; furthermore, this conclusion points the way toward the development of a speculative radicalist mode of engagement and imagination that is capable of meeting the challenges of the Anthropocene

Community gardens: A natural way to wellbeing

Community gardens provide social, economic and environmental benefits to local urban communities. These include individual and collective social wellbeing, access to cheap, nutritious food and improved functioning of the local ecology. Although regarded by some as a neutral project to organise a community around, community gardening is still highly political. When planned, organised and run by local people and located centrally in the community, (particularly disadvantaged communities) these green spaces offer multiple health benefits that prevent disease and promote wellbeing, a sense of citizen control and social capital. Most indicators suggest that community gardening movement has enjoyed varied success in building healthier Sydney communities. However the intrinsic effects of this low cost, low-tech community process is hard to compare and measure. Challenges include security of tenure, establishing appropriate policy and planning guidelines with local councils and departments, ensuring active and full participation of those community groups 'at risk' and developing persuasive evaluation systems to meet these challenges. It is suggested that community gardens reflect the wider social, cultural, structural elements in the society as well as the human processes that ultimately enable or restrict healthy living

Course Manual: International Workshop-cum-Training Programme on "Fisheries and Aquaculture"

Marine fisheries contribute to food, nutrition, employment and income generation in India. The sector supports about four million people for their livelihood and nearly one million fishermen by way of employment and contributes significantly to the export earnings of the country and balance of trade. The sector contributes to an economic wealth valued at nearly US$10 billion annually. The marine fisheries of the country consist of small-scale and artisanal fishers belonging mechanized, motorized and non-mechanized sectors and a range of other stakeholders, including governmental and nongovernmental agencies. Though India is not a leading producer in true mariculture we are second in aquaculture production after China. Coastal aquaculture of shrimp has a major role in aquaculture production and export in India. Even though there is vast scope, recently only India has taken up mariculture technologies to the stake holder level. Due to the success achieved mariculture, it has been identified as a potential source of production enhancement for high valued species like lobster, seabass, cobia and pompano for which the capture fishery is negligible
