This book was released on 2017 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this thesis is to develop a computational human musculoskeletal model to investigate the change in the kinematic behavior of the model's lower extremities under the influence of activated (active) and deactivated (passive) muscles during a representation frontal collision using OpenSim software. Since OpenSim is seldom used in crash simulations, an appropriate model evaluation is performed by comparing the model's kinematics, obtained from the OpenSim's inverse dynamic simulation, against LS-DYNA's explicit non-linear side impact simulation of a finite element model for a car-pedestrian collision. The required musculoskeletal model is constructed in OpenSim and scaled to meet the requirements of the Hybrid III 50th Percentile crash test dummy. For evaluating the developed model, the kinematics from both programs (OpenSim and LS-DYNA), containing identical displacement data, is compared by visual observation of identical time frames. Using the evaluated model in the forward dynamics domain of OpenSim, a representative frontal crash simulation is conducted for the active and passive muscle states of the model, and the kinematic difference in its lower extremities is observed and compared. The results were also compared to MADYMO's human body model simulations conducted under similar conditions. This study indicates that the role of the muscle activation on the human body responses during a car collision is important. The novel technique developed and utilized in this study is shown to be quite useful in modeling and simulation of a car occupant's real kinematic response during a car collision.
Book Synopsis Characterizing, Modeling, and Predicting the External Ground Reaction Forces of Legged Movement by : Paweł Kudzia
Download or read book Characterizing, Modeling, and Predicting the External Ground Reaction Forces of Legged Movement written by Paweł Kudzia and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, I explore legged agility with a primary focus on controlling external ground reaction forces produced by our legs. I conduct empirical studies and develop models to understand how we control external forces and develop innovative means to measure them. My research consists of four aims, each contributing to our understanding of human performance and driving potential advancements in sports, robotics, and rehabilitative technologies. In Aim 1, I characterize the control of leg external forces (n=14). To achieve this, I construct a mechanical system and a real-time visual feedback system to capture force magnitudes and positions exerted by my leg. Using system identification, I gain insights into the control of leg external forces across different magnitudes and positions. In Aim 2, I examine the effects of neuromuscular fatigue on our nervous system's capacity to control leg external forces (n=18). I hypothesize that heightened fatigue results in a decrease in both the responsiveness and accuracy of leg force control. My results reveal a significant reduction in mean maximum force production, leading to a substantial decline in my leg force control responsiveness. These findings enhance our understanding of how fatigue influences agility and may guide strategies to sustain performance in the presence of fatigue. In Aim 3, I set out to understand the limit of vertical jumping by studying the external forces generated during jumping (n=10). I develop physics-based models of varying complexity to predict external forces during vertical jumps and identify the simplest model that accurately predicts human-like forces. This model, capable of simulating jumps from different depths, highlights the significance of force-velocity properties and maximal force as limiting factors for jump height. In Aim 4, I develop a novel approach to estimate the external forces generated by each leg during vertical jumps. Using a transformer-based neural network and video data (n=30), I demonstrate that the model accurately predicts each leg's external forces, offering a new tool for measuring jump height and forces from video. My work aims to make biomechanical analysis accessible, a task typically confined to laboratory settings. In summary, this thesis investigates the control of leg external forces, the effects of fatigue, and the development of predictive models. It underscores the potential of machine learning in biomechanical analysis, contributing to a broader understanding of human performance and paving the way for new technological advancements.
Book Synopsis Lower Extremity Finite Element Model for Crash Simulation by :
Download or read book Lower Extremity Finite Element Model for Crash Simulation written by and published by . This book was released on 1996 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: A lower extremity model has been developed to study occupant injury mechanisms of the major bones and ligamentous soft tissues resulting from vehicle collisions. The model is based on anatomically correct digitized bone surfaces of the pelvis, femur, patella and the tibia. Many muscles, tendons and ligaments were incrementally added to the basic bone model. We have simulated two types of occupant loading that occur in a crash environment using a non-linear large deformation finite element code. The modeling approach assumed that the leg was passive during its response to the excitation, that is, no active muscular contraction and therefore no active change in limb stiffness. The approach recognized that the most important contributions of the muscles to the lower extremity response are their ability to define and modify the impedance of the limb. When nonlinear material behavior in a component of the leg model was deemed important to response, a nonlinear constitutive model was incorporated. The accuracy of these assumptions can be verified only through a review of analysis results and careful comparison with test data. As currently defined, the model meets the objective for which it was created. Much work remains to be done, both from modeling and analysis perspectives, before the model can be considered complete. The model implements a modeling philosophy that can accurately capture both kinematic and kinetic response of the lower limb. We have demonstrated that the lower extremity model is a valuable tool for understanding the injury processes and mechanisms. We are now in a position to extend the computer simulation to investigate the clinical fracture patterns observed in actual crashes. Additional experience with this model will enable us to make a statement on what measures are needed to significantly reduce lower extremity injuries in vehicle crashes. 6 refs.

Available in PDF, EPUB and Kindle. Book excerpt: Richly illustrated and presented in clear, concise language, Biomechanics of Skeletal Muscles is an essential resource for those seeking advanced knowledge of muscle biomechanics. Written by leading experts Vladimir Zatsiorsky and Boris Prilutsky, the text is one of the few to look at muscle biomechanics in its entirety—from muscle fibers to muscle coordination—making it a unique contribution to the field. Using a blend of experimental evidence and mechanical models, Biomechanics of Skeletal Muscles provides an explanation of whole muscle biomechanics at work in the body in motion. The book first addresses the mechanical behavior of single muscles—from the sarcomere level up to the entire muscle. The architecture of human muscle, the mechanical properties of tendons and passive muscles, the biomechanics of active muscles, and the force transmission and shock absorption aspects of muscle are explored in detail. Next, the various issues of muscle functioning during human motion are addressed. The transformation from muscle force to joint movements, two-joint muscle function, eccentric muscle action, and muscle coordination are analyzed. This advanced text assumes some knowledge of algebra and calculus; however, the emphasis is on understanding physical concepts. Higher-level computational descriptions are placed in special sections in the later chapters of the book, allowing those with a strong mathematical background to explore this material in more detail. Readers who choose to skip over these sections will find that the book still provides a strong conceptual understanding of advanced topics. Biomechanics of Skeletal Muscles also contains numerous special features that facilitate readers’ comprehension of the topics presented. More than 300 illustrations and accompanying explanations provide an extensive visual representation of muscle biomechanics. Refresher sidebars offer brief reminders of mathematical and biomechanical concepts, and From the Literature sidebars present practical examples that illustrate the concepts under discussion. Chapter summaries and review questions provide an opportunity for reflection and self-testing, and reference lists at the end of each chapter provide a starting point for further study. Biomechanics of Skeletal Muscles offers a thorough explanation of whole muscle biomechanics, bridging the gap between foundational biomechanics texts and scientific literature. With the information found in this text, readers can prepare themselves to better understand the latest in cutting-edge research. Biomechanics of Skeletal Muscles is the third volume in the Biomechanics of Human Motion series. Advanced readers in human movement science gain a comprehensive understanding of the biomechanics of human motion as presented by one of the world’s foremost researchers on the subject, Dr. Vladimir Zatsiorsky. The series begins with Kinematics of Human Motion, which details human body positioning and movement in three dimensions; continues with Kinetics of Human Motion, which examines the forces that create body motion and their effects; and concludes with Biomechanics of Skeletal Muscles, which explains the action of the biological motors that exert force and produce mechanical work during human movement.
Book Synopsis Contact Force Models for Multibody Dynamics by : Paulo Flores
Download or read book Contact Force Models for Multibody Dynamics written by Paulo Flores and published by Springer. This book was released on 2016-03-15 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes several compliant contact force models within the context of multibody dynamics, while also revisiting the main issues associated with fundamental contact mechanics. In particular, it presents various contact force models, from linear to nonlinear, from purely elastic to dissipative, and describes their parameters. Addressing the different numerical methods and algorithms for contact problems in multibody systems, the book describes the gross motion of multibody systems by using a two-dimensional formulation based on the absolute coordinates and employs different contact models to represent contact-impact events. Results for selected planar multibody mechanical systems are presented and utilized to discuss the main assumptions and procedures adopted throughout this work. The material provided here indicates that the prediction of the dynamic behavior of mechanical systems involving contact-impact strongly depends on the choice of contact force model. In short, the book provides a comprehensive resource for the multibody dynamics community and beyond on modeling contact forces and the dynamics of mechanical systems undergoing contact-impact events.

This book was released on 2009-07-08 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The temporomandibular joint (TMJ) is a site of intense morbidity for millions of people, especially young, pre-menopausal women. Central to TMJ afflictions are the cartilaginous tissues of the TMJ, especially those of the disc and condylar cartilage, which play crucial roles in normal function of this unusual joint. Damage or disease to these tissues significantly impacts a patient's quality of life by making common activities such as talking and eating difficult and painful. Unfortunately, these tissues have limited ability to heal, necessitating the development of treatments for repair or replacement. The burgeoning field of tissue engineering holds promise that replacement tissues can be constructed in the laboratory to recapitulate the functional requirements of native tissues. This book outlines the biomechanical, biochemical, and anatomical characteristics of the disc and condylar cartilage, and also provides a historical perspective of past and current TMJ treatments and previous tissue engineering efforts. This book was written to serve as a reference for researchers seeking to learn about the TMJ, for undergraduate and graduate level courses, and as a compendium of TMJ tissue engineering design criteria. Table of Contents: The Temporomandibular Joint / Fibrocartilage of the TMJ Disc / Cartilage of the Mandibular Condyle / Tissue Engineering of the Disc / Tissue Engineering of the Mandibular Condyle / Current Perspectives

Download or read book International Perspectives on Spinal Cord Injury written by World Health Organization and published by World Health Organization. This book was released on 2013 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Every year between 250 000 and 500 000 people suffer a spinal cord injury, with road traffic crashes, falls and violence as the three leading causes. People with spinal cord injury are two to five times more likely to die prematurely. They also have lower rates of school enrollment and economic participation than people without such injuries. Spinal cord injury has costly consequences for the individual and society, but it is preventable, survivable and need not preclude good health and social inclusion. Ensuring an adequate medical and rehabilitation response, followed by supportive services and accessible environments, can help minimize the disruption to people with spinal cord injury and their families. The aims of International perspectives on spinal cord injury are to: ---assemble and summarize information on spinal cord injury, in particular the epidemiology, services, interventions and policies that are relevant, together with the lived experience of people with spinal cord injury; ---make recommendations for actions based on this evidence that are consistent with the aspirations for people with disabilities as expressed in the Convention on the Rights of Persons with Disabilities.

Book Synopsis Smartphone-Based 3D Indoor Localization and Navigation by : Frank Ebner
Download or read book Smartphone-Based 3D Indoor Localization and Navigation written by Frank Ebner and published by Logos Verlag Berlin GmbH. This book was released on 2021-01-10 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last century, navigation systems have become ubiquitous and guide drivers, cyclists, and pedestrians towards their desired destinations. While operating worldwide, they rely on line-of-sight conditions towards satellites and are thus limited to outdoor areas. However, finding a gate within an airport, a ward within a hospital, or a university's auditorium also represent navigation problems. To provide navigation within such indoor environments, new approaches are required. This thesis examines pedestrian 3D indoor localization and navigation using commodity smartphones: A desirable target platform, always at hand and equipped with a multitude of sensors. The IMU (accelerometer, gyroscope, magnetometer) and barometer allow for pedestrian dead reckoning, that is, estimating relative location changes. Absolute whereabouts can be determined via Wi-Fi, an infrastructure present within most public buildings, or by using Bluetooth Low Energy Beacons as inexpensive supplement. The building's 3D floorplan not only enables navigation, but also increases accuracy by preventing impossible movements, and serves as a visual reference for the pedestrian. All aforementioned information is fused by recursive density estimation based on a particle filter. The conducted experiments cover both, theoretical backgrounds and real-world use-cases. All discussed approaches utilize the infrastructure found within most public buildings, are easy to set up, and maintain. Overall, this thesis results in an indoor localization and navigation system that can be easily deployed, without requiring any special hardware components.
