The Life of Lines Template: Royal A, Font: , Date: 12/03/2015; 3B2 version: 10.0.1465/W Unicode (Dec 22 2011) (APS_OT) Dir: //integrafs1/kcg/2-Pagination/TandF/LOL_RAPS/ApplicationFiles/9780415576857_text.3d The Life of Lines ‘In The Life of Lines Ingold develops a philosophical and ecological anthropology that is at once expansive, integrative, and inclusive. His poetic narrative interlaces bodies, minds, landscapes, topographies, and perceptions in a correspondence of lines. Taking us on a journey through movement, knots, weather, atmosphere and surfaces, he guides us to a critical conclusion: to human is a verb.’ Agustín Fuentes, University of Notre Dame, USA To live, every being must put out a line, and in life these lines tangle with one another. This book is a study of the life of lines. Following on from his groundbreaking work Lines: A Brief History, Tim Ingold offers a stunningly original series of meditations on life, ground, wind, walking, imagination and what it means to be human. A world of life is woven from knots; not built from blocks as commonly thought. Ingold shows how knotting underwrites both the way things join with one another – in walls, buildings and bodies – and the composition of the ground and the knowledge we find there. To study living lines we must also study the weather. To complement his linealogy, Ingold develops a meteorology that seeks the common denomi- nator of breath, time, mood, sound, memory, colour and the sky. This denominator is the atmosphere. Finally, Ingold carries the line into the domain of human life. For life to continue, he argues, the things we do must be framed within the lives we undergo. In continually answering to one another, these lives enact a principle of correspondence that is fundamentally social. This compelling volume brings our thinking about the material world vividly back to life. While anchored in anthropology, the book ranges over an interdisciplinary terrain that includes philosophy, geography, sociology, art and architecture. Tim Ingold is Professor of Social Anthropology at the University of Aberdeen, UK. His books for Routledge include Lines: A Brief History (2007), The Perception of the Environment (reissued 2011), Being Alive (2011) and Making: Anthropology, Archaeology, Art and Architecture (2013).

And that was that. Life intervened, as it always does, in the form not of opportunities to write my lines, but of the incessant demands of academic employment. I had been meaning to complete the book for years, and had been accumulating bits and pieces of writing with a view to putting them all together once a suitable moment would arrive. But it never did. Days, weeks and months ticked by, and I was still no closer to composing the book than when the year began. Indeed almost seven years had elapsed since I first ventured into print on the subject of lines. My book Lines: A Brief History was published in 2007. Yet even before the ink was dry on the manuscript, I already knew that I would have to write some sort of sequel. Not knowing exactly what it would be about, I filed it in my head as Lines 2. All I knew was that it would have something to do with lines and the weather. For I had found, rather to my surprise, that thinking about lines always brought thoughts about the weather in its wake, and vice versa. Why was that, I wondered? Perhaps it only proved that I had completely lost the plot. Any level-headed reader, for whom the idea that an anthropologist can study lines is hard enough to swallow, would surely conclude that to take off into the atmosphere is to go completely off the rails. What business has an anthropologist encroaching on territory that rightfully belongs to the science of meteorology, or maybe to students of aesthetics? These doubts nagged at me too, and yet the idea of a unified field of linealogy and meteorology would not let me go. An opportunity to contribute to the inspirational series of seminars that anthropologist and ex-architect Trevor Marchand convened at the School of Oriental and African Studies in London, in 2007, and to the subsequent volume, provided me with an excuse to begin to set my thoughts on paper, and a Professorial Fellowship funded by the UK Economic and Social Research Council for the three years 2005–8afforded me a window of time to do so.

  • Rug Buying Guide Find the Perfect Rug for Any Space
    Rug Buying Guide Find the perfect rug for any space. Learn more about rug construction, sizes, material, style, and care. The right rug can do more than just help define a space. It can protect your floors from wear and tear while adding to a visually appealing aesthetic with its colors and patterns. However, purchasing a rug is no easy task. You must consider your lifestyle, placement of the rug, design of the rug, and what you will need from a rug. We’ve compiled the ultimate guide to help you find the exact rug that will fulfill the needs of your space. Rug Weaves The weave of a rug can determine the feel, look, and durability overtime. Although rugs can now be made more efficiently, there are still many craftsmen who tediously weave rugs by hand. Hand-Knotted Hand-knotted rugs are very labor intensive with lasting results. They are very durable and can last for over 20 years with minimal shedding. The most common fiber used is wool. Because hand-knotted rugs are very labor intensive to create, they can take on average 5-7 months to be completed, sometimes even longer. The time and labor put into creating a hand-knotted rug does make it considerably pricier than other. Weavers will begin by hand tying knots onto warps before tying tufts of wool around the warp creating knots. The end of knots create the pile. Wefts are then threaded through in order to tighten the knots. This creates the foundation of the rug. The more knots per inch, the more intricate the pattern, and usually the more durable the knots will be.

Gonzalez1, Ken Goldberg1 Abstract—Robot manipulation for untangling 1D deformable structures such as ropes, cables, and wires is challenging due to their infinite dimensional configuration space, complex dynamics, and tendency to self-occlude. Analytical controllers often fail in the presence of dense configurations, due to the difficulty of grasping between adjacent cable segments. We present two algorithms that enhance robust cable untangling, LOKI and SPi- DERMan, which operate alongside HULK, a high-level planner from prior work. LOKI uses a learned model of manipulation features to refine a coarse grasp keypoint prediction to a precise, optimized location and orientation, while SPiDERMan uses a learned model to sense task progress and apply recovery actions. We evaluate these algorithms in physical cable untangling experiments with 336 knots and over 1500 actions on real cables using the da Vinci surgical robot. We find that the combina- tion of HULK, LOKI, and SPiDERMan is able to untangle dense overhand, figure-eight, double-overhand, square, bowline, granny, stevedore, and triple-overhand knots. The composition of these methods successfully untangles a cable from a dense initial configuration in 68.3% of 60 physical experiments and achieves 50% higher success rates than baselines from prior work.

The influence of variables on compression behavior of carpets has been quantitatively analyzed by using response surface methodology based on the Box-Behnken design of experiment. The minimum compression occurs with the combination of minimum values of pile height (10 mm), knot density (5 knots/inch) & number of ply in pile yarn (2 ply), and maximum value of pile yarn twist (4.5 twists/inch). However the maximum compression recovery is attained with the combination of minimum values of pile height (10 mm) & pile yarn twist ( 3.5 twists/inch), and maximum values of knot density (7 knots/inch) & number of ply in pile yarn (4 ply).

  • Evaluating Pile Yarn Characteristics in Hand Woven Carpet Using Stress-Strain Behavior in Compression
    EVALUATING PILE YARN CHARACTERISTICS IN HAND WOVEN CARPET USING STRESS-STRAIN BEHAVIOR IN COMPRESSION A.R. Moghassem* Faculty of Engineering, Textile Engineering Group, Islamic Azad University Qaemshahr Branch, P.O. Box 163 Qaemshahr, Iran [email protected] A.A. Gharehaghaji Department of Textile engineering, Isfahan University of Technology P.O. Box 8415683111, Isfahan, Iran [email protected] *Corresponding Author (Received: August 19, 2007 - Accepted in Revised Form: May 9, 2008) Abstract Many factors such as production methods and structural parameters have distinctive influence on the quality and performance of a hand woven carpet. To investigate the effects of some variables, eighteen samples of carpet vary, in knot density, pile height and percentage of slipe wool, were manufactured. Pile yarn performance was assessed by using load-displacement compression curve, obtained from Zwick tensile tester under cyclic loading, up to 30 kPa. Based on the results, compression and matting of the pile yarn decreased and its elastic recovery increased with the increase in knot density. Increase in pile height caused an increase in the degree of variation for carpet samples. Matting of samples decreased with increase in pile height to certain level, but further increase caused increased reduction in matting. Elastic recovery of pile yarn had a reverse trend as the pile height changed. Consequently, increase in percentage of slipe wool caused an increase in compression and matting, and also reduction in elastic recovery of pile yarn.
