PAPER PRESENTATION

Here is the summarised abstract of a paper presentation i made on DNA COMPUTATION

What it is?. DNA computing is a form of computing which uses DNA and molecular biology, instead of the traditional silicon-based computer
The Origin- Adleman was struck by how how a living enzyme "reads" DNA much the same way computer pioneer 1936is was calculated how a machine could read data.
If you look inside the cell you find a bunch of amazing little tools,The cell is a treasure chest. ?
Adleman used his computer to solve the classic problems there by drawing similarity between dna strand and the computer.For example -"traveling salesman" mathematical problem -- how a salesman can visit a given number of cities without passing through any city twice -- by exploiting the predictability of how DNA interacts. He generated thousands of random paths, in much the same way that a computer can sift through random numbers to break a code.
Advantages-
The primary advantage offered by most proposed models of DNA based computation is the ability to handle millions of operations in parallel. The massively parallel processing capabilities of DNA computers may give them the potential to find tractable solutions to otherwise intractable problems, as well as potentially speeding up large, but otherwise solvable, polynomial time problems requiring relatively few operations. The use of DNA to perform massive searching and related algorithms will be referred to as "classic" DNA computation for the purposes of this discussion. Proposed "classical" models of DNA computers derive their potential advantage over conventional computers from their ability to: Perform millions of operations simultaneously; Generate a complete set of potential solutions; Conduct large parallel searches; and Efficiently handle massive amounts of working memory. of optimal encoding techniques, and the ability to perform necessary bio-operations conveniently in vitro or in vivo.

. . Disadvantages-
Biologists are only now grasping the basics of how and why DNA unzips, recombines and sends and receives information. DNA is notoriously fragile and prone to transcription errors -- as the world's cancer rate thus a lot a work is still required for it to be success.
A limited amount of work has been directed at real-life applications and the practical feasibility of DNA computers. While the practical benefits of DNA based computational schemes are still questionable and the vast majority of work to date has been theoretical, there have been many allusions to
These models also have some of the following drawbacks: Each stage of parallel operations requires time measured in hours or days, with extensive human or mechanical intervention between steps; Generating solution sets, even for some relatively simple problems, may require impractically large amounts of memory; and Many empirical uncertainties, including those involving: actual error rates, the generation
The future-These realizations and others have tempered initial expectations that DNA would ultimately replace silicon chips. Still, researchers in this field believe they remain on the vanguard of a computational revolution. After all, a single gram of dried DNA, about the size of a half-inch sugar cube, can hold as much information as a trillion compact disk.

EXAM FEVER

They are finally over.....

Like a fire breathing dragon it reared its ugly head upon us. It vultured upon our sorry state hovering high with a killer instinct looking down upon its’ preys smelling blood and hoping to extract blood soon. Some fared well whereas some cursed their luck. Some rejoiced in victory whereas some sank deep into the deep, dark sea of despair. May be we (at least I) were partly to be blamed for our this state but I cant help to think that SATAN himself had planed this massacre for us. But Alas! they are finally over. The one good thing I can say surely about all of us is that we all SURVIVED it
Examination times are crucial times this all of know very well. But I have tumbled upon a new discovery in my latest encounter with them. They are also dam FUNNY times.
In a herculean sized hostel like mine where student of all imaginable brain sizes and level of preparation interact you are bound to have your ‘gut-aching’ moment.
IT WAS FUNNY when a certain BATCH TOPPER went to sleep every night, during the exam at sharp 10 pm (even during the CORE ECE papers) and woke up at 9 in the morning. He was genuinely surprised when all of us gasped at this act of horror. Although all of us knew that he was going to get double the marks that any one of us (those who l studied all night long) could possibly get.
IT WAS FUNNY when the coolest stud of our batch decided to sleep out the exam period(not just in his room but also in the examination hall). He confessed ‘One night preparation won’ t do me much good so it is better if I save my energy for the summers’. He and our BATCH TOPPER slept long and well. The irony (again quite funny) was that they were doing the same activity but for reasons that were poles apart.
IT WAS FUNNY when a very superstitious person decided to were the same pair of jeans throughout the examination. His reason was ‘I had worn this pair in the first exam. I had not studied much but did well. It was because of my lucky jeans. So I intend to were it in all my examinations’. All I could think off was that ‘Thank God he had a bath in the first day. This prevented him from coming to the conclusion that not taking a bath was lucky for him. Thus our nostrils were spared from much torture’.
IT WAS certainly FUNNY quiet a lot of times during our examination I just hope that it will still be funny when our results come out.

THE APPLICATION

MY lovable institute is up to its old tricks again making us do the most illogical activities which has no practical implications attached whatsoever.
This time around we students who had missed any of their classes on the 1st or 2nd of March are suppose to write an application justifying their this heinous crime. We are required to submit it with our respective teachers.
On 2nd we had only a single lecture, having finally realized that MID-SEM was rearing its ugly face over us the majority of the class didn’t show up.(But almost all showed up in CP or MX fanatically searching for tuite sheet sols…..)
So on the first day after midsem we got our rude shock. We were supposed to write the dam thing and submit it then and there. Synchronous sounds of pages being torn filled the air. All of started banging our heads hard, desperately trying to remember the great art of writing an ‘APPLICATION’. It was a crisis. I firmly believe that panic leads to humor. The actions which followed reaffirmed my faith.
In the small time frame given to us we filled our blank papers’ with some ink and submitted it. I being seated in the first row was forced to keep turning back and collect the applications which were being passed on from behind. I passed them on but not before having a sneak peak of the reason provided.
They came in all sizes and forms and finally left me gasping for air.
We obviously had the usual alibis-‘I had fever/cold/migraine…..’. Some went a step ahead and wrote that they even had the med-cert and will be more than happy to provide it if required. May be they were trying reverse psychology-if they say they have I they won’t be asked to provide it.
Some said that they had stomach ache and added that the reason for their sorry state was the uneatable mess food. Talk about killing two birds with one stone.
One was truly outrageous-‘Sir as I had more than 75% attendance, I felt no need to attend the class’. Talk about sticking it in your face. Courageous or foolish you decide.
Another one said , as I desperately had to go to the loo and the institute levorotary made me(I think all) nauseous I had no option but to go back to my hostel.
But this one had to the show stealer –‘As 2nd was the last working day before Holi , I was fully aware of a possible holi bash. Afraid of this I decided to hide myself in the safe vicinities of my hostel room’.
One can make that some of the outrageous alibis were intentionally written that way. A way of getting back …..i guess. But one can’t help to imagine if actually these were true reasons.
Weird but very hilarious.
PS-None mentioned about bunking class to prepare for midsem.
