Cerebral compliance patterns during normal sleep.

Arquivos de Neuro-Psiquiatria
Background: The morphology of the intracranial pressure pulse consists of three waves: P1, corresponding to arterial pulsation; P2, corresponding to cerebral compliance; and P3, corresponding to aortic valve closure. Under normal conditions, P1> P2> P3.

STATIC THORACIC COMPLIANCE IN NORMAL CHILDREN UNDER GENERAL ANAESTHESIA

Acta Anaesthesiologica Scandinavica, 1971
SUMMARYThere is relatively little information concerning the relationship between body size and the components of thoracic compliance in normal children. Static compliance was measured in 40 normal children under general anaesthesia. Their heights (Ht.) ranged from 90 to 175 cm.

Is Lamina Propria Matrix Responsible for Normal Bladder Compliance?

Journal of Urology, 1992
Immunohistochemistry using monoclonal and polyclonal antibodies to extracellular matrix proteins is a highly sensitive tool for the characterization of matrix components. For the first time in the normal and noncompliant human bladder we have used antibodies to collagen types I, III and IV, and elastin to provide morphological correlation with ...

Static respiratory compliance in normal dogs

Journal of Small Animal Practice, 1991
ABSTRACTStatic respiratory compliance was measured in a series of normal dogs. The values (mean SEM) for total compliance (n = 42), pulmonary compliance (n = 42) and chest wall compliance (n = 93) were 61 (3–8), 82 (4–7) and 94 (3‐3) ml/ cmH20, respectively. There was a strong positive correlation between bodyweight and chest wall circumference and all

Normal forms of stiffness and compliance matrices

IEEE Journal on Robotics and Automation, 1987
A generalized spring associates potential energy with each position and orientation of a rigid body. The stiffness of such a spring can be represented by a 6 × 6 symmetric matrix. This matrix can be brought to a normal form by a particular choice of the coordinate frame. Analogous but independent results hold for compliance matrices.

A Simplified Exact Compliance Normal-Directional Contact Model

Volume 4B: Dynamics, Vibration, and Control, 2016
Contact is the most abundant phenomena in the field of multi-body dynamics, experienced when two or more bodies come in close vicinity to each other. During contact, one body virtually penetrates within other and therefore is subjected to a large impulsive force due to the deformation; this is the essence of the compliance based models.

Pulmonary arterial compliance at rest and exercise in normal humans

American Journal of Physiology-Heart and Circulatory Physiology, 1990
We evaluated the feasibility of determining pulmonary arterial compliance (Cp) by a parameter estimation procedure based on the three-element windkessel model. Eight normal patients studied with multisensor micromanometry technology had simultaneous rest and exercise pulmonary artery pressures (PAP) and flows recorded.

A Non-clamped Frictional Contact Problem with Normal Compliance

2015
In this chapter we study a dynamic frictional contact problem with normal compliance and non-clamped contact conditions, for thermo-viscoelastic materials. The weak formulation of the problem leads to a general system defined by a second order quasivariational evolution inequality coupled with a first order evolution equation.
