A color model is a system that creates a full range of colors from a small set of primary colors. There are two main types of color models: additive and subtractive. Additive color models like RGB use light to display colors on screens by combining red, green, and blue light, starting with black and ending with white. Subtractive color models like CMYK use pigments to print colors, starting with white and ending with black by combining cyan, magenta, yellow, and black inks. RGB is used for digital displays while CMYK is used for print because it reflects how inks absorb and reflect light.

Image formats
The document discusses several common image file formats: TIFF, JPEG, GIF, PNG, and EXIF. TIFF files are uncompressed, high quality images used in design software. JPEG files are for photographs and use lossy compression for smaller file sizes. GIFs use lossless compression but have a limited color palette, making them suited for images with few colors like logos. PNG is an alternative to GIF with better compression and more colors. EXIF stores camera metadata in JPEG files.

Color and color models
Color is a sensation produced by the human visual system. The two most common color models are RGB, used for computer displays, and CMYK, used for printing. RGB is an additive model that uses combinations of red, green, and blue light to produce colors. CMYK is a subtractive model that uses combinations of cyan, magenta, yellow, and black inks to produce colors. Both models represent colors using three numeric values corresponding to the intensities of the primary colors.
Graphic Design Fundamentals
Graphic design elements like line, color, shape, and texture are the basic building blocks used to create visual compositions. Key principles for effective design include movement, balance, emphasis, and unity. Movement can be created through lines, repetition, or blurred edges, while balance considers the distribution of empty and filled space as well as different colors, textures, and elements. Emphasis and unity help focus the message by stressing key points or creating harmony.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

RGB & CMYK Color Model
- 1. Color Model Presented By: Md. Asif Shahariar Shovan Banik Iftekher Aziz 162-15-7772 162-15-7790 162-15-8182
- 2. A color model is a system for creating a full range of colours from a small set of primary colors. What is Color Model?
- 4. CIE XYZ Color Space
- 5. Additive Color Models Additive color mixing is creating a new color by a process that adds one set of wavelengths to another set of wavelengths.
- 6. Additive Color Models Con. If we are working on a computer: • The colors we see on the screen are created with light using the additive color method. • Additive color mixing begins with black and ends with white. • AS more color is added, the result is lighter and tends to white.
- 7. Subtractive Color Models Subtractive color mixing occurs when we mix paints, dyes, or pigments. Subtractive color mixing occurs when we mix paints, dyes, or pigments
- 8. Subtractive Color Models Con. When we mix colors using paint: • We use subtractive color method. • Subtractive color mixing means that one begins with white and ends with black • As one adds color, the result gets darker and tends to black
- 9. Cylindrical-coordinate Color Model A number of color models exist in which colors are fit into conic, cylindrical or spherical s hapes, with neutrals running from black to white along a central axis, and hues corresponding to angles around the perimeter.
- 10. RGB Color Model • Additive Color Model • For Computer Display • Uses light to display color • Colors result from transmitted light • Red + Green + Blue = White
- 11. RGB Color Model Con. • The RGB Colors are light primaries and colors are created with light • Percentages of Red, Green & Blue are used to generate color on a computer screen.
- 12. Importance of RGB Color Model • Used in hardware applications like PC monitors, cameras and scanners. • It is used for Web graphics, but it cannot be used for print production. • It directly reflects the physical properties of “True-color” displays.
- 13. Importance of RGB Color Model Con. • It also used in sensory representation • Display of text images in electronic system (Computer, T.V., Camera)
- 14. CMYK Color Model • Subtractive Color Model • For Printed Material • Uses ink to display color • Colors result from reflected light • Cyan + Magenta + Yellow = Black
- 15. Importance of CMYK Color Model • The CMY color model is used in color printers. • It is created by the subtractive model. • Used in most commercial color printing.(Books, Magazines etc.)
- 16. Numeric representation • A typical RGB color selector in graphic software Each slider ranges from 0 to 255. • Hexadecimal 8-bit RGB representation of the main 125 colors. • A color in the RGB color model is described by indicating how much of each of the red, green and blue is included
- 17. Numeric representation Con. • If all the components are at zero the result is black • If all are at maximum, the result is the brightest represent able white.
- 18. Conversion Policy RGB to CMYK • The R, G, B values are divided by 255 to change the range form 0.255 to 0.1 • R = R/255 • G = G/255 • Y = Y/255
- 19. Conversion Policy RGB to CMYK • K = 1 – max (R, G, B) • C = ( 1 – R – K ) / ( 1-K) • M = ( 1 – G – K ) / ( 1-K) • Y = ( 1 - B – K ) / ( 1-K)
- 20. Difference between RGB & CMYK
- 21. Difference between RGB & CMYK • RGB is an additive type of color mode • That combines the primary colors • RGB is vibrant • All three colors are combined it will pure white • CMYK is a four-color mode • Combines cyan, magenta, yellow and black • Not vibrant but good for reading • Not pure black, but rather a very dark brown
- 22. Thank You
