What is sinusoidal sequence?
A sinusoidal sequence is the fundamental periodic signal having just one single frequency. The top two rows depict the periodic sequences, and their magnitude spectral sequences with positive and negative frequency components.
What is hepatic sinusoidal system?
The hepatic sinusoid is a unique, dynamic, microvascular structure that serves as the principal site of exchange between the blood and the perisinusoidal space (i.e., space of Disse).
What is sinusoidal cell?
Summary. Liver sinusoidal endothelial cells (LSECs) are highly specialized endothelial cells representing the interface between blood cells on the one side and hepatocytes and hepatic stellate cells on the other side. LSECs represent a permeable barrier.
What are sinusoids in physics?
A sine wave or sinusoid is any of certain mathematical curves that describe a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph.
Why are sinusoidal signals important?
One reason for the importance of sinusoids is that they are fundamental in physics. Many physical systems that resonate or oscillate produce quasi-sinusoidal motion. Another reason sinusoids are important is that they are eigenfunctions of linear systems (which we’ll say more about in §4.1. 4).
What do sinusoids carry?
The sinusoids carry blood from the edges of the lobule to the central vein. The sinusoids are lined by two types of cell 1) phagocytic cells called Kupffer cells (macrophages), which phagocytose dead red blood cells, particulate matter, and micro-organisms.
What type of vessel is sinusoid?
Capillaries are composed of only the tunica intima, consisting of a thin wall of simple squamous endothelial cells. They are the smallest blood vessels in the body: they convey blood between the arterioles and venules….

How is a sinusoid represented mathematically?
A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave’s angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.
Are sine waves transverse?
A sine wave(function) is a conceptual/mathematical wave(function). It in neither transverse nor longitudinal. However, a phenomenon such as an SHM or WAVE ON STRING(transverse) or WAVE ON WATER SURFACE or SOUND WAVE (longitudinal)may be represented by a sinusoidal(sine) wave function.
What is sinusoidal in signal and system?
Sine Wave or Sinusoidal Wave Signal is a special type of signal. It is given by the function. When Sine wave starts from zero and covers positive values, reaches zero; and again covers negative values, reaches zero, it is said to have completed one cycle or single cycle.
What are the uses of a sinusoidal waveform?
In 1822, French mathematician Joseph Fourier discovered that sinusoidal waves can be used as simple building blocks to describe and approximate any periodic waveform, including square waves. Fourier used it as an analytical tool in the study of waves and heat flow.
What is sinusoidal fetal heart rate?
A sinusoidal fetal heart rate pattern is a well-documented sign of massive maternal-fetal hemorrhage and is seen as a smooth, sine-like undulating pattern with a cycle frequency of three to five cycles per minute that persists for >20 minutes.1 It is most commonly associated with fetal anemia or hypoxia. 1
What does sinusoid mean?
SINUSOID. • SINUSOID (noun) The noun SINUSOID has 2 senses: 1. tiny endothelium-lined passages for blood in the tissue of an organ 2. the curve of y=sin x Familiarity information: SINUSOID used as a noun is rare.
What is sinusoidal alternating current?
Sinusoidal Current. an alternating current that constitutes a sinusoidal function of time in the form i = Im sin (ωt + Φ), where i is the instantaneous value of the current, Im is the current’s amplitude, ω is the angular frequency, and Φ is the initial phase angle.
