Book excerpt: In this, the third issue of Joe Biel's award-winning, ongoing look at the Critical Mass movement, we are given a well-researched analysis at the history of bicycle activism and police spying in Portland, Oregon. The result is an engaging and readable combination of story, activism, and history. Over the course of 44 pages, Biel looks at why a city so bike-friendly as Portland has virtually no Critical Mass ride, while cataloging the ways the Portland Police Department has interacted with local riders and historic activism. Says Biel, "It's concerning how many times a cyclist has repeated to me the police's version of Portland's cycling history or how years later new rumors are created about what happened." Strange and inspiring, Bipedal, By Pedal #3 is essential, illuminating reading for cyclists and non-cyclists alike.

Book excerpt: For the second issue of the Expozine Award–winning Bipedal, By Pedal, editor Joe Biel has collected legal documents pertaining to the Portland Police Department's nefarious, illegal crackdown campaign on the local Critical Mass movement. Obtained by Freedom of Information Act requests, Biel shows through once-secret police and court documents that Portland Critical Mass did not in fact die out: it was brutally torn down by the cops in an organized campaign of intimidation and spy work. A rally call for bike activists, this zine is a companion piece to Biel's upcoming documentary, Aftermass: A Post Critical Mass Portland. For a humorous touch, the police documents are redone as Mad Libs.

Download or read book Feedback Control of Dynamic Bipedal Robot Locomotion written by Eric R. Westervelt and published by CRC Press. This book was released on 2018-10-03 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bipedal locomotion is among the most difficult challenges in control engineering. Most books treat the subject from a quasi-static perspective, overlooking the hybrid nature of bipedal mechanics. Feedback Control of Dynamic Bipedal Robot Locomotion is the first book to present a comprehensive and mathematically sound treatment of feedback design for achieving stable, agile, and efficient locomotion in bipedal robots. In this unique and groundbreaking treatise, expert authors lead you systematically through every step of the process, including: Mathematical modeling of walking and running gaits in planar robots Analysis of periodic orbits in hybrid systems Design and analysis of feedback systems for achieving stable periodic motions Algorithms for synthesizing feedback controllers Detailed simulation examples Experimental implementations on two bipedal test beds The elegance of the authors' approach is evident in the marriage of control theory and mechanics, uniting control-based presentation and mathematical custom with a mechanics-based approach to the problem and computational rendering. Concrete examples and numerous illustrations complement and clarify the mathematical discussion. A supporting Web site offers links to videos of several experiments along with MATLAB® code for several of the models. This one-of-a-kind book builds a solid understanding of the theoretical and practical aspects of truly dynamic locomotion in planar bipedal robots.
Download or read book Bipedal Robots written by Christine Chevallereau and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents various techniques to carry out the gait modeling, the gait patterns synthesis, and the control of biped robots. Some general information on the human walking, a presentation of the current experimental biped robots, and the application of walking bipeds are given. The modeling is based on the decomposition on a walking step into different sub-phases depending on the way each foot stands into contact on the ground. The robot design is dealt with according to the mass repartition and the choice of the actuators. Different ways to generate walking patterns are considered, such as passive walking and gait synthesis performed using optimization technique. Control based on the robot modeling, neural network methods, or intuitive approaches are presented. The unilaterality of contact is dealt with using on-line adaptation of the desired motion.

Download or read book The system of species of African bipedal primates from 6 2 0 9 mya written by Sergey Vyrskiy and published by Litres. This book was released on 2022-01-29 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here we report the establishment of a family relation system between the species of African bipedal primates observed in deposits from 6.2 to 0.9 million years ago (mya).For this purpose, the author presents a single method of assigning diagnostic “weight” when conducting character assessment of fossilized remains and has also formulated several equations and ratios that make use of morphometric measurements and can be used to predict the crucial parameters of paleontological individuals, such as body weight, endocranial volume, and cerebral index, and identify their diet.Having simultaneously considered all the morphometric descriptions of the bone remains of bipedal primates and, by a single method of character evaluation, having established the degree of their affinity, the author reconstructed the phyletic lines, uniting almost all diagnostically significant samples and systematized paleoanthropological material of the 6.2–0.9 mya period.The evaluation of the phyletic-associated fossils, in compliance with the Biological Species Concept (E. Mayr), revealed the existence of only two species of bipedal primates in the African continent at the beginning of the period under consideration. Later, a new, third, species emerged, the formation of which correlated with the exponential increase in the cerebral index and the advent of the first stone tools.

Download or read book Reading Prehistoric Human Tracks written by Andreas Pastoors and published by Springer Nature. This book was released on 2021 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book explains that after long periods of prehistoric research in which the importance of the archaeological as well as the natural context of rock art has been constantly underestimated, research has now begun to take this context into focus for documentation, analysis, interpretation and understanding. Human footprints are prominent among the long-time under-researched features of the context in caves with rock art. In order to compensate for this neglect an innovative research program has been established several years ago that focuses on the merging of indigenous knowledge and western archaeological science for the benefit of both sides. The book gathers first the methodological diversity in the analysis of human tracks. Here major representatives of anthropological, statistical and traditional approaches feature the multi-layered methods available for the analysis of human tracks. Second it compiles case studies from around the globe of prehistoric human tracks. For the first time, the most important sites which have been found worldwide are published in a single publication. The third focus of this book is on firsthand experiences of researchers with indigenous tracking experts from around the globe, expounding on how archaeological sciencecan benefit from the ancestral knowledge. This book will be of interest to professional archaeologists, graduate students, ecologists, cultural anthropologists and laypeople, especially those focussing on hunting-gathering and pastoralist communities and who appreciate indigenous knowledge.--

Download or read book Apes and Human Evolution written by Russell H. Tuttle and published by Harvard University Press. This book was released on 2014-02-17 with total page 1089 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes—sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture—speech, mating proscriptions, kinship structures, and moral codes—are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.
Download or read book From Biped to Strider written by D. Jeffrey Meldrum and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inspiration for this volume of contributed papers stemmed from conversations between the editors in front of Chuck Hilton's poster on the determinants of hominid walking speed, presented at thel998 meetings of the American Association of Physical Anthropologists (AAPA). Earlier at those meetings, Jeff Meldrum (with Roshna Wunderlich) had presented an alternate interpretation of the Laetoli footprints based on evidence of midfoot flexibility. As the discussion ensued we found convergence on a number of ideas about the nature of the evolution of modem human walking. From the continuation of that dialogue grew the proposal for a symposium which we called From Biped to Strider: the Emergence of Modem Human Walking. The symposium was held as a session of the 69th annual meeting of the AAPA, held in San Antonio, Texas in 2000. It seemed to us that the study of human bipedalism had become overshadowed by theoften polarized debates over whether australo pithecines were wholly terrestrial in habit, or retained a significant degree of arboreality.
Download or read book The Evolution of the Primate Foot written by Angel Zeininger and published by Springer Nature. This book was released on 2022-12-07 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human foot is a unique and defining characteristic of our anatomy. Most primates have grasping, prehensile feet, whereas the human foot stands out as a powerful non-grasping propulsive lever that is central to our evolution as adept bipedal walkers and runners and defines our lineage. Very few books have compiled and evaluated key research on the primate foot and provided a perspective on what we know and what we still need to know. This book serves as an essential companion to “The Evolution of the Primate Hand” volume, also in the Developments in Primatology series. This book includes chapters written by experts in the field of morphology and mechanics of the primate foot, the role of the foot in different aspects of primate locomotion (including but not limited to human bipedalism), the “hard evidence” of primate foot evolution including fossil foot bones and fossil footprints, and the relevance of our foot’s evolutionary history to modern human foot pathology. This volume addresses three fundamental questions: (1) What makes the human foot so different from that of other primates? (2) How does the anatomy, biomechanics, and ecological context of the foot and foot use differ among primates and why? (3) how did foot anatomy and function change throughout primate and human evolution, and why is this evolutionary history relevant in clinical contexts today? This co-edited volume, which relies on the insights of leading scholars in primate foot anatomy and evolution provides for the first time a comprehensive review and scholarly discussion of the primate foot from multiple perspectives. It is accessible to readers at different levels of inquiry (e.g., undergraduate/graduate students, postdoctoral research, other scholars outside of biological anthropology). This volume provides an all-in‐one resource for research on the comparative and functional morphology and evolution of the primate foot.
