Amwoga KhalwaleWhat Is Optical Character Recognition (OCR)? The main purpose of optical character recognition is to quickly and automatically recognize and convert images of machine-printed or typed text into actual electronic data that users can organize, search and modify. In general, an OCR engine analyzes the pixel data of scanned images and searches for patterns resembling … Read more
SVG File (Scalable Vector Graphics) SVG (Scalable Vector Graphics) is an Extensible Markup language-based vector image format for two-dimensional graphics with support for interactivity and animation. It was developed in 1999 by Wide Web Consortium. SVG files are developed as a standard format for displaying vector graphics on the web. SVG is based on XML … Read more
What Is Waveguide? A wave guide is a specialized structure that guides waves such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. It is designed to channel and manipulate electromagnetic energy along a specific path while minimizing losses and radiation. Waveguides are hollow metal … Read more
Voltage Amplifier A voltage amplifier is an amplifier that amplifies given voltage for a larger voltage output. It is characterized by a high input impedance and low output impedance. This is useful for reading and adapting small signals such as boosting an audio signal before sending it on its way to speakers. The voltage amplifier … Read more
What Is Epigeal? Epigeal germination is a type of germination whereby the seed leaves or the cotyledons are brought on to the surface or above the soil along with the shoot during germination. This is usually due to rapid elongation and curved-like shape of the hypocotyl. This change in the shape or curvature of the … Read more
Virtual Circuits Virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. Before the data transfer begins, the source and destination identify a suitable … Read more
Enzymes Enzymes are biological molecules typically proteins that speed significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve as a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large … Read more
Joint Photographic Experts Group (JPEG) JPEG is an acronym for ‘’ Joint Photographic Experts Group”. It’s a standard image format for containing lossy and compressed image data. Despite the huge reduction in file size JPEG images maintain reasonable image quality. This unique compression feature allows JPEG files to be used widely on the internet, computers … Read more
What Is SN1 Reaction? The SN1 reaction is a substitution reaction in organic chemistry. ‘’SN’’ stand for ‘’nucleophilic substitution’’ and ‘’1’’ says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of … Read more
DNA is a two-stranded molecule. One strand of DNA holds the information that codes for various genes, this often referred to as the template strand or antisense strand (containing anticodons). The other complementary strand is referred to as the coding strand or sense strand (containing codons). What Is Template Strand? Transcription is the process in … Read more
