MODERN OPTICAL FIBER by GEC WRITHLON on Wednesday, April 01, 2020 in ELECTRONICS INTRODUCTION: Fiber-Optic Communication is that the latest and advanced mode of knowledge communication which has very recent roots dating back to less than 40 years ago, this was the main breakthrough in the field of communication. Right from this time, there has been a continuously increasing need for bandwidth for communication due to continuously increasing the number of users. More people wanted to speak , and thus large bandwidths were required thereby forcing communication scientists to seem for brand spanking new possibilities. Communication Scientists everywhere the planet were in an incessant look for a wideband and low-loss medium of knowledge communication which might be used at high data rates with the least amount of lost possibly. This constant search, for such a medium, led to the event of glass fiber communication. gecwrithlon.blogspot.com
Gaganyaan Mission of ISRO In the recent Independence Day speech, Honorable Prime Minister Shri Narendra Modi announced the Gaganyaan Program of ISRO that would take Indian astronauts to space. On the occasion of the 75th year of Independence of India ISRO will undertake a manned mission on board 'Gaganyaan Mission' which will be carrying the Indian national flag. The Indian Space Research Organization (ISRO) currently working on the Gaganyaan Mission. This will be the proud moment of India because before this Indian astronaut Rakesh Sharma had the opportunity to go to space. Now, the time has changed and after Rakesh Sharma, India has also a new opportunity to be achieved. Basically, what is Gaganyaan Mission? The Gaganyaan mission is the first manned mission of our Country. This will be the first time for the India that our country will launch its manned mission into space, making the country fourth in line to have sent a human to space. Behind the name Gaganyaan Gaganyaan sounds like the Sanskrit word Gagan=Sky & Yaan=Vehicle. "Gaganyaan=SkyVehicle" which will be the formative the manned spacecraft of the Indian Space agency ISRO. About the Spacecraft In its starting mission, the autonomous spacecraft of ISRO's which is of 3.7-tonne (8,200 lb) capsule size will orbit the surface of Earth at 400 km (250 mi) altitude for up to seven days with three-person crew on board. The entire designing of this spacecraft to carry three crew members at a time. In its starting mission, the autonomous spacecraft of ISRO's which os of 3.7-tonne (8,200 lb) capsule size will orbit the surface of Eart at 400 km (250 mi) altitude for up to seven days with three-person crew on board. The probable launching date of the crewed vehicle is on the GSLV Mk III (Geosynchronous Satellite Launch Vehicle Mark III) in December 2021. This first un-crewed experimental flight of this crew is on 18 December 2014. In May 2019, the final design of the crew module has been completed. On this super Gaganyaan Mission ISRO will send a humanoid Robot named Vyomitra. On January 22, 2020, ISRO announced about the female Robot Vyomitra will give the company to the crew members in the mission. The name Vyomitra is the combination of two words Vyom=Sky & Mitra= Friend thus Vyomitra= Sky's Friend. She is capable of to give out warnings if environmental changes will occur. She can also perform tasks and take commands to take up postures that will be suited for the launch. Follow the below link to know about Vyomitra Robot. https://www.youtube.com/watch?v=-NYnImrqleY&t=73s Total Expenditure in Gaganyaan Mission The total cost of the Gaganyaan Mission Program is approx. Rs.10,000 crore which includes the cost of using technologies development, spacecraft hardware and essential infrastructure elements of the capsule. Benefits of this mission. ▪ The main benefits of the Gaganyaan Mission that this program will establish a dynamic framework between Indian space agency ISRO to the other. ▪ This mission is purely based on our country made technology. ▪ The flight system realization of the used spacecraft will be through our entire Industry. ▪ It seems to generate employment and train human resources in advanced technologies. ▪ It will inspire a large number of young students and also motivate them to the innovation world of science & technology. https://gecwrithlon.blogspot.com/2020/03/gaganyaan-mission-of-isro.html?m=1
Man and Machine Machines are the creation of humans, and they were created to make their work easier. Humans depend more and more on machines for their day-to-day things. Machines have created a revolution, and no human can think of a life without machines. A machine is only a device consisting of different parts, and is used for performing different functions. They do not have life, as they are mechanical. On the other hand, humans are made of flesh and blood; life is just not mechanical for humans. https://gecwrithlon.blogspot.com/2020/03/man-and-machine.html?m=1

Cnc Machine Technology CNC's full name is computer numerical control. This is an unconventional machine. Machine-tools and workpiece are controlled by the computer, they are called CNC machines. In this, the motion of the workpiece and tools is controlled with the help of pre-built programs. The CNC machine is also used in 3D printing. https://gecwrithlon.blogspot.com/2020/01/cnc-machine-technology.html?m=1
