Available in PDF, EPUB and Kindle. Book excerpt: A three dimensional discrete model of human spine, torso and head has been refined and validated by comparison with available experimental results. The model consists of a system of rigid bodies, representing the head, vertebrae, and ribs, interconnected by deformable elements which represent the intervertebral discs, ligaments, and other connective tissues. Four models of varying orders of complexity have been developed, ranging from a complex model to a very simplified model with 32 degrees of freedom. The simplified model is able to closely reproduce many of the response characteristics of the more complex models in G sub z loadings, and, because of its simplicity and short running time, may be well suited for design use. Experimental results for human subjects suitable for validation of models are primarily available in the form of impedance curves for vertical harmonic excitation so techniques were developed which efficiently obtain impedance curves for the model. Comparisons of the impedance curves show good agreement, both in the magnitudes and locations of peaks. Furthermore, it was shown that the primary peaks in the impedance curve in the 5 to 7 Hz range result from a combination of buttock-seat resonance, the flexural response of the spine and visceral resonance. Analogous head-spine models were developed for the chimpanzee, baboon, and rhesus monkey. The objective of this development was to provide a scaling methodology for dynamic response and injury data among these non-human primates and man. Impedance curves are presented for these models and show significant differences in character from that of the human spine models.

Available in PDF, EPUB and Kindle. Book excerpt: Biomechanics aims to explain the mechanics oflife and living. From molecules to organisms, everything must obey the laws of mechanics. Clarification of mechanics clarifies many things. Biomechanics helps us to appreciate life. It sensitizes us to observe nature. It is a tool for design and invention of devices to improve the quality of life. It is a useful tool, a simple tool, a valuable tool, an unavoidable tool. It is a necessary part of biology and engineering. The method of biomechanics is the method of engineering, which consists of observation, experimentation, theorization, validation, and application. To understand any object, we must know its geometry and materials of construc tion, the mechanical properties of the materials involved, the governing natural laws, the mathematical formulation of specific problems and their solutions, and the results of validation. Once understood, one goes on to develop applications. In my plan to present an outline of biomechanics, I followed the engineering approach and used three volumes. In the first volume, Biomechanics: Mechanical Properties of Living Tissues, the geometrical struc ture and the rheological properties of various materials, tissues, and organs are presented. In the second volume, Biodynamics: Circulation, the physiology of blood circulation is analyzed by the engineering method.

Available in PDF, EPUB and Kindle. Book excerpt: Biomedical Engineering II: Recent Developments covers some progress made in biochemical engineering, which have some useful application in dentistry, medical instrumentation, and orthopedics. The book provides a detailed testing and analysis of the use of hydroxylapatite as an effective substance for mandibular augmentation of the atrophic ridge. An in-depth report about the technique called the tendon reroute surgery is also given. The book includes a discussion on cardiology hemodynamics, which is about the determination of blood flow by monitoring the speed of blood cell. Another topic covered is the effects of stresses on the vertebral body. A separate section of the book is focused on the modeling and creation of simulation to test the movement of transmicrovascular fluid and protein exchanges. Some topics in the field of bioelectricity, biomechanics, and biocontrol systems are thoroughly discussed. The text will be a useful tool for dentists, orthopedics, doctors, and people in the field of medical physiology.

Download or read book Biophysics of Computation written by Christof Koch and published by Oxford University Press. This book was released on 2004-10-28 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural network research often builds on the fiction that neurons are simple linear threshold units, completely neglecting the highly dynamic and complex nature of synapses, dendrites, and voltage-dependent ionic currents. Biophysics of Computation: Information Processing in Single Neurons challenges this notion, using richly detailed experimental and theoretical findings from cellular biophysics to explain the repertoire of computational functions available to single neurons. The author shows how individual nerve cells can multiply, integrate, or delay synaptic inputs and how information can be encoded in the voltage across the membrane, in the intracellular calcium concentration, or in the timing of individual spikes.Key topics covered include the linear cable equation; cable theory as applied to passive dendritic trees and dendritic spines; chemical and electrical synapses and how to treat them from a computational point of view; nonlinear interactions of synaptic input in passive and active dendritic trees; the Hodgkin-Huxley model of action potential generation and propagation; phase space analysis; linking stochastic ionic channels to membrane-dependent currents; calcium and potassium currents and their role in information processing; the role of diffusion, buffering and binding of calcium, and other messenger systems in information processing and storage; short- and long-term models of synaptic plasticity; simplified models of single cells; stochastic aspects of neuronal firing; the nature of the neuronal code; and unconventional models of sub-cellular computation.Biophysics of Computation: Information Processing in Single Neurons serves as an ideal text for advanced undergraduate and graduate courses in cellular biophysics, computational neuroscience, and neural networks, and will appeal to students and professionals in neuroscience, electrical and computer engineering, and physics.
Download or read book A Model for Analytic Investigation of Three Dimensional Head Spine Dynamics written by T. Belytschko and published by . This book was released on 1976 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three dimensional, discrete model of the human spine, torso and head was developed for the purpose of evaluating mechanical response in pilot ejection and it was developed in sufficient generality to be applicable to other body response problems, such as occupant response in aircraft crash and arbitrary loads on the head-spine system. There are no restrictions on the distribution or direction of applied loads, so a wide variety of situations can be treated. Results are presented for a variety of conditions, such as different rates on onset, ejection at angles, effects on lumbar curvature, and eccentric head loadings. It is shown that large initial curvatures and perfectly vertical acceleration loadings result in substantial flexural response of the spine, which cause large bending moments. It is further shown that the combination of the spines low flexural stiffness, initial curvature, and mass eccentricity are such that stability cannot be maintained in a 10 g ejection without restraints or spine-torso-musculature interaction.
