What is a difference between passing by value and passing arguments by reference in visual basic 6 procedures?
When we pass arguments my value, we are passing the value represented in the variable mentioned in the call, and not the variable itself. Therefore, any modifications made to that value will NOT be reflected in the variable mentioned in the call. Pass by reference, as the name suggests passes the reference of the variable mentioned in the procedure call. Any modifications made to the data of that variable is changed at the memory location of that data itself, and will be reflected in the variable itself, after the procedures completes.
Give the difference between LPF and HPF?
LPF is a low pass LTI filter which passes the low frequency signals and reduce the amplitude of the signals with frequencies higher than the cutoff frequency. HPF is high pass LTI filter which passes the high frequencies and reduce the amplitude of the frequencies lower than filter's cutoff frequency.
What is color fundamentals?
Color Fundamentals• The process followed by the human brain in perceiving and interpreting color is a physiopsychological phenomenon that is not yet fully understood, the physical nature of color can be expressed on a formal basis supported by experiment and theoretical results.• In 1666, Sir Isaac Newton discovered that when a beam of sunlight passes through a glass prism, the emerging beam of light us not white but consist instead of a continuous spectrum of colors ranging from violet at one end to red at the other.• Visible light is composed of a relatively narrow brand of frequencies in the electromagnetic spectrum.• If the light is achromatic (void of color), its only attribute is its intensity, or amount.• Achromatic light is what viewers see on a black and white television set.• Chromatic light spans the electromagnetic spectrum from approximately 400 to 700 nm.• Three basic quantities are used to describe the quality of a chromatic light source: radiance, luminance, and brightness.- Radiance is the total amount of energy that flow from the light source, and it is usually measured in watts (W).- Luminance, measured in lumens (lm), gives a measure of the amount of energy an observer perceives from a light source.- Brightness is a subjective descriptor that is practically impossible to measure. It embodies the achromatic notion of intensity and is one of the key factors in describing color sensation.• 6 to 7 million cones in the human eye can divided into three principal sensing categories, corresponding roughly to red, green, and blue.• Approximately 65% of all cones are sensitive to red light, 33% are sensitive to green light, and only about 2% are sensitive to blue (but that blue cones are the most sensitive).• Due to these absorption characteristics of the human eyes, colors are seen as variable combinations of the so-called primary colors red (R), green (G), and blue (B).• It is important to keep in mind that having three specific primary color wavelengths for the purpose of standardization does not mean that these three fixed RGB components actin alone can generate all spectrum colors.• The primary colors can be added to produce the secondary colors of light - magenta (red plus blue), cyan (green plus blue), and yellow (red plus green).• The characteristics generally used to distinguish one color from another are brightness, hue, and saturation.• Hue is an attribute associated with the dominant wavelength in a mixture of light waves.• Hue represent dominant color as perceived by an observer.• Saturation refers to the relatives purity or the amount of white light mixed with a hue.• The pure spectrum color are fully saturation.• Hue and saturation taken together are called chromaticity, and therefore, a color may be characterized by its brightness and chromaticity.• CIE chromaticity diagram (Fig 6.5), which show color composition as a function of x (red) and y (green).• Any point not actually on the boundary but within the diagram represents some mixture o spectrum colors.• A straight-line segment joining any two points in the diagram defines all the different color variations that can be obtained by combining these two colors additively.• The triangle in Figure 6.6 shows a typical range of colors (called the color gamut) produced by RGB monitors.• The irregular region inside the triangle is representative of the color gamut of today's high- quality color printing devices.• The boundary of the color printing gamut is irregular because color printing is a combination of additive and subtractive color mixing, a process that is much more difficult to control than that of displaying colors on a monitor.Color Models• RGB (red, green, blue) model for color monitors and a board class of color video cameras.• CMY (cyan, magenta, yellow) and CMYK (cyan, magenta, yellow, black) models for color printing.• HIS (hue, saturation, intensity) model, which corresponds closely with the way humans describeand interpret color.• The HIS model also has the advantage that it decouples the color and gray-scale information in animage, making it suitable for many of the gray-scale techniques.N.

How can you tell if a graph show a FUNCTION?
By doing a vertical line test. If you can draw a vertical line and it only passes through the graph once, its a function. If it passes through twice, it is NOT a function.
When is it not a function?
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
Can a parabola represent a function?
If a vertical line passes through the supposed function at only one spot then you have a function.
How do you link a programming with other programming languages?
This is done via a call sequence. The syntax is different between languages but the process is about the same. The calling program issues a call to the called program and passes data items known as arguments. These arguments are used to instruct the called program on what actually to do. After the called program has completed its function it passes these arguments back to the calling program along with a return code to inform the calling program everything was ok, or not ok.
What is the main function of each level?
Interprets the law passes improves.
What is the function of the parnasal sinuses to the skull?
its when air passes within the skull
Why is y equals -8 a function?
y = -8 is a function because when graphed, it passes the vertical line test.
Where might one go on the internet to find out how to travel by train in Europe?
InterRail is a great company to use when traveling Europe. They offer multiple types of passes which include one country passes, Europe passes, and global passes.
How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
(-1,0),(-1),(-3,1),(-3,1) it is a function or not?
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
Function left atrium?
It receives and passes oxygen-rich (oxygenated) blood (from lungs) into the left ventricle which passes into the aorta and then throughout the body.
What is the functions the rectum?
Its main function is as a passage which fecal matter passes through.
