These questions are important form the point of view of the 2nd term test.

Hello friends! I am Sarita Joshi perusing my Final year of Computer Engineering from VCET.

The past 3 tears were indeed memorable. With a great hustle and bustle we enjoy our moments together with equal concentration and hard work towards our studies.

My academic Achievements:-

·         Stood first in first year Computer Engineering

·         Stood first in my second year Computer Engineering

·         Stood first in my third year Computer Engineering

In fact my academic record i.e. aggregate of all the last 3 years is round about 79% which is the highest among all the five branches students.

Sounds great, but all became possible just because of my Mantra,

“Put your Best and You deserve the Best.”

Hard work, dedication and the sincere efforts towards a given task will definitely help one to reach the pinnacle of success.

Some useful tips from my side,

·         Before you start with all stuff, have a clear idea about your destination, where you want to land on.

·         Refer recommended books (that doesn't only mean Reference books). Books that can actually help you to clear your concepts.

·         Take help of our seniors regarding the study material.

·         Avoid bunking lectures if possible.

·         Studies should be a part of daily routine i.e. everyday a bit will definitely help one a lot rather than waiting for the PL.

·         Use the PL in a best possible way and while studying have a syllabus copy in front of you, so as to know what to study and what not to.

This was all about the do's and dont's that one must follow to come up with bright colors and mark one's presence.

Ending up with acads, friends these four years are the best moments to develop one's individual personality. Studies are must but along with it one needs to focus on various extra curricular activities. Lastly I would end up saying....

“Forget the past and no worries about the future,

Just enjoy your present in the best possible way.”

GOOD LUCK!!!

 

Devendra from FE A, who scored 82% in Sem II and emerged as the topper, has shared his secret with us. We would like to wish Devendra all the best his future life. Devendra is currently studying in SE EXTC.

This article will be useful for all those who wish to score good marks in Engineering. It will especially be useful for freshers which are new to the world of engineering follows are some useful tips which may help them to study:-

1)      First of all, there is no shortcut to success. Practical is very much essential. Punctuality and regularity in practice is needed in subjects like math and mechanics.

2)      For studying theoretical subjects like Physics and Chemistry, first go through all the past university papers and highlight the important and frequently asked questions from various chapters. Prepare those questions first and then if time permits, go on to study further new topics. Otherwise, studying these subjects would be a huge task.

3)      For theoretical answer for e.g. characteristics, uses, properties of something, etc., pneumonic can become very handy to remember the answers instead of merely mugging them up.

4)      For practical or application based subjects like Mechanics, Cp, Ed you have no choice but to understand the basic concepts. Just solving a huge no of problems without understanding the concepts is useless. Instead, you should understand the concept first and solve sufficient amount and variety of problems.

5)      Now, some tips about writing the paper. However, tough or easy the paper may be, never get excited or panicked. Just relax, keep your mind cool and write at a moderate speed. Just keep a check on time and accordingly adjust your speed.

6)      Accuracy in answers is the most important thing. Attempting 80 marks out of 100 and scoring 70 is always better than attempting 140 and getting an ATKT.

7)      Also a certain degree of neatness is expected in answer paper.

8)      Don’t go on to express those points which are not needed. Otherwise, valuable time is lost which can be used to answer other questions.

9)      Answer those questions first about which you are fully confident and most perfect. Start with easy ones rather than difficult/ time consuming questions. First impression should be the best one. (Remember that the order in which you answer is not at all important.)

10)   At 10 min before the end of the exam, always recheck your paper (whether you have completed the paper or not). Add required points wherever necessary. Never give any scope to cut your marks.

11)   And last but not the least; never over-exert yourself, especially during exam time. Always give some time for sports/ extra-curricular activities and always be updated of knowledge. Proper time management plays a very important role in engineering.

The autonomous AirPenguins do more than just fly

In many ways, autonomous robots are like toddlers. They need to learn their limits. They must also discover how to play nice with others. And, like toddlers, they often fall down trying.

Nowhere was this more on evident than the Hanover Fair display of German automation specialist, Festo AG & Co. One side of the company's long space was crammed with pneumatic and electrical actuators and control systems similar to those in the booths around it. The other side contained the toys. These included a wall of lightweight pylons that interacted by moving as people walked by and a huge aquarium containing three mechanical penguins that interacted with one another as they swam.

Festo has a history of producing audacious autonomous robots for Hanover Fair, and these displays were no exception. Yet the company's most impressive display was taking place above the heads of the onlookers, where three flying penguins interacted with one another in tight airspace above Festo's booth.

Penguins, of course, cannot fly. Festo's AirPenguins, however, are balloons with bodies made of carbon fiber rod and extruded polyurethane foam under metalized foil. Each one measures 3.7 meters long and 0.9 meter deep with a 2.5-meter wingspan. Each flying penguin carries a complete control system, battery pack, an assortment of sensors, and servos to power the wings, nose, and tail. The entire ensemble weighs one kilogram.

Providing consistent yet autonomous behaviors to Festo's AirPenguin proved a major challenge for Kristof Jebens and Agalya Nagarathinam, an engineering team based in Gärtringen, Germany.

To enable the AirPenguins to interact with one another in their confined airspace—just 3.5 meters above the area of the Festo booth—Jebens first had to synchronize their wing movements through use of a wireless timing signal. "Without synchronization, if they came close, the turbulence would suck them in and they would crash," Jebens said.

By eliminating a turbulence sensor, Jebens and Nagarathinam could concentrate on what was really important: avoiding the AirPenguin's most feared predator—the building's air conditioning system.

Festo had been down this road before. One year at Hanover Fair, the company featured manta ray-like balloons with wings that moved up and down. The large, flat surfaces made a perfect target for a downdraft. When the balloons flew under an air conditioning vent, any downdraft would push them into the booth.

The AirPenguins are far more versatile. Their wings not only move up and down, but also pivot to propel them forward like a swimmer doing the breaststroke. Their nose and tail bend also, allowing them to lean into turns like a real penguin in the water for faster response.

To take advantage of this mechanical flexibility, Jebens and Nagarathinam designed the AirPenguins to carry an array of sensors. For instance, a receiver enables the balloons to triangulate their position in space by listening to three ultrasonic stations located around the Festo booth. They are also equipped with a compass and three-axis accelerometer, which tell the AirPenguin if it is level or tilted, and allow the robot to calculate yaw for more-precise quick turns.

The AirPenguins also contain an air pressure sensor sensitive enough to calculate altitude to within 10 centimeters. When Jebens and Nagarathinam tested the system in Festo's high-roofed corporate lounge, that sensor worked fine. At Hanover Fair, where Festo's booth is always crowded, updrafts from the body heat of visitors and drafts from open doors made it harder for the AirPenguins to use pressure data to determine their height. The AirPenguins, however, could deduce their height from the ultrasonic beacons around the booth.

The ultrasonic receiver and pressure sensors alert the AirPenguin when a draft of cold air from the air conditioner is pushing it down. The robot might try to fly around the flow of cold air or dive into it to increase its speed and then turn sharply away.

Sometimes it works. Other times, the AirPenguins crash. When the balloons are flying, Festo technicians hold backup controls in case anything goes wrong. In the end, while Festo's AirPenguins show complex behaviors, they also have a lot of conventional automation safeguards built in as well.

"You have to do that if you want to have a nice show," Jebens said. "Sometimes, if you try to make them more adaptive, it doesn't work as well. For the software to adapt, you need lots of cycles. We don't want it to start learning while all the visitors are coming to the booth."

In other words, clean the toddlers up before company comes and hope that in a few years, they will have learned how to behave and play nice with others on their own.
