DevOps is nothing new, but since its inception in 2008, a growing number of firms have embraced it in order to remain competitive, keep one step ahead of their rivals, and improve the customer experience. Git Git is a distributed version control system that makes it easier to create, modify, and track software (like CVS, Subversion, etc.). Given that they both refer to comparable properties, "Git" and "VCS" are used interchangeably in this article. Users may create, modify, and monitor changes to projects using a version control system, which is a piece of software. A VCS is a best practice ... Read More

Robotic limbs have been around for a while; and with the ongoing new technologies and innovations, have been able to get better in motion and strength. The latest development in robotic limbs is that of the ‘click-on arm’ prosthesis.There have been other mind-controlled robotic devices used for patients with severe disabilities either due to neuro-degenerative diseases or accidents. But for these robotic devices, the brain is implanted with chips to enable the movements of robotic arms. The click-on prosthetic device has been applied to legs and been around for a while now (since 2009); however, it has been used on ... Read More

Yagi-Uda antenna is the most commonly used type of antenna for TV reception over the last few decades. It is the most popular and easy-to-use type of antenna with better performance, which is famous for its high gain and directivity. The frequency range in which the Yagi-Uda antennas operate is around 30 MHz to 3 GHz which belong to the VHF and UHF bands.Construction of Yagi-Uda AntennaA Yagi-Uda antenna was seen on top of almost every house during the 90's when we had only Doordarshan Channels. The parasitic elements and the dipole together form this Yagi-Uda antenna. It is seen ... Read More

Microstrip antennas are the low-profile antennas. A metal patch mounted on a ground level with a dielectric material in-between constitutes a Microstrip or Patch Antenna. These are very low size antennas having low radiation. The patch antennas are popular for low profile applications at frequencies above 100MHz.Construction and workingThe microstrip consists of a very thin metallic strip placed on a ground plane with a dielectric material in-between. The radiating element and feed lines are placed by the process of photo-etching on the dielectric material. Usually, the patch or microstrip is chosen to be square, circular or rectangular in shape for ... Read More

Babinet’s Principle is actually the principle used in optics. According to its definition, “When the field behind a screen with an opening is added to the field of a complementary structure, the sum is equal to the field when there is no screen”The images clearly explain the principle. In all the regions, which are non-collinear with the beam, the above two screens, in figure 1 & 2, produce the same diffraction pattern.Case1Consider a light source and a conducting plane (field) with an aperture before a screen. The light does not pass through the opaque area but passes through the aperture.Case2Consider ... Read More
