    Internally supported flexible duct joint

    Get PDF
    An internally supported, flexible duct joint for use in conducting fluids under relatively high pressures in systems where relatively large deflection angles must be accommodated is presented. The joint includes a flexible tubular bellows and an elongated base disposed within the bellows. The base is connected through radiating struts to the bellows near mid-portion and to each of the opposite end portions of the bellows through a pivotal connecting body. A motion-controlling linkage is provided for linking the connecting bodies, whereby angular displacement of the joint is controlled and uniformity in the instantaneous bend radius of the duct is achieved as deflection is imposed

    Adversarial PoseNet: A Structure-aware Convolutional Network for Human Pose Estimation

    Full text link
    For human pose estimation in monocular images, joint occlusions and overlapping upon human bodies often result in deviated pose predictions. Under these circumstances, biologically implausible pose predictions may be produced. In contrast, human vision is able to predict poses by exploiting geometric constraints of joint inter-connectivity. To address the problem by incorporating priors about the structure of human bodies, we propose a novel structure-aware convolutional network to implicitly take such priors into account during training of the deep network. Explicit learning of such constraints is typically challenging. Instead, we design discriminators to distinguish the real poses from the fake ones (such as biologically implausible ones). If the pose generator (G) generates results that the discriminator fails to distinguish from real ones, the network successfully learns the priors.Comment: Fixed typos. 14 pages.

    Climate of Opportunity: Gender and Movement Building at the Intersection of Reproductive Justice and Environmental Justice

    Get PDF
    Women's reproductive health and rights are inextricably linked to environmental health and justice issues. Women's bodies and reproductive health are often the markers of environmental contamination through diminished fertility, fetal developmental disabilities and increased rates of cancers. Beginning in 2008, the Foundation brought together grant partners working in these two movements to form the Environmental Justice/Reproductive Justice (EJ/RJ) Collaborative. The Foundation has seen firsthand how joint advocacy generates more inclusive movements and stronger outcomes for communities. This report summarizes the EJ/RJ Collaborative as a reference for funders, policymakers, organizations and others interested in joint advocacy work

    Recursive multibody dynamics and discrete-time optimal control

    Get PDF
    A recursive algorithm is developed for the solution of the simulation dynamics problem for a chain of rigid bodies. Arbitrary joint constraints are permitted, that is, joints may allow translational and/or rotational degrees of freedom. The recursive procedure is shown to be identical to that encountered in a discrete-time optimal control problem. For each relevant quantity in the multibody dynamics problem, there exists an analog in the context of optimal control. The performance index that is minimized in the control problem is identified as Gibbs' function for the chain of bodies

    Arthroscopic Removal of Metal Foreign Bodies from the Knee Joint after Explosive War Injuries

    The results of arthroscopic removal of metallic fragments from knee joint due to explosive war injuries are presented. In period from 1991–1995 during war in Croatia we have operated 25 knee joints. Indications for arthroscopy were based on radiographic and clinical findings. The foreign bodies in the joint were found in 19 patients while additional 6 had foreign bodies in the periarticular soft tissues. Arthroscopies were performed on average one month after wounding. The foreign bodies were placed in different parts of the joint with no prediction sites. In 8 knees foreign bodies were freely mobile, and in 11 were anchored to different intraarticular structures. There were no complications during early postoperative period as well as in follow up period

    The trading of unlimited liability bank shares: the Bagehot Hypothesis

    Get PDF
    From the mid-1820s, banks became the first business sector in Great Britain and Ireland to be granted the right to form freely on an unlimited liability joint stock basis. Walter Bagehot, the renowned contemporary banking expert, warned that shares in such banks would ultimately be owned by widows, orphans and other impecunious individuals. An alternative hypothesis is that the governing bodies of these banks constrained by special legal restrictions on share trading acted effectively to prevent such shares being transferred to the less wealthy members of society. We test both conjectures using the archives of an Irish joint stock bank. The results do not support Bagehot's hypothesis, but instead indicate that shares continued to be owned by wealthy individuals.unlimited liability, corporate governance, joint stock companies, banking

    Arthroscopic treatment of bucket-handle labral tear and acetabular fracture

    Get PDF
    Traumatic hip dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the joint. These types of injury often lead to traumatic arthritis. In some cases an osseo-labral fragment may become incarcerated in the joint that is not readily visualized preoperatively. In place of open surgery, hip arthroscopy permits a technique to remove loose bodies and repair labral tears to restore joint congruity and achieve fracture reduction and fixation
