How IITB's Departments Fare in terms of Patents

13:30 Eeshan Malhotra 1 Comments

IIT Bombay has always been a frontrunner in terms of ideas and innovation. In fact, IITB was awarded the National Intellectual Property Award, 2015 for being the Top India Academic Institution for Patents. Of course, we wanted to see the numbers behind the scenes, and decided to take a look at all the patents IITB has filed in the last few years. Since 2000, researchers in the institute have filed over 500 patents.

As you can see, the growth in recent years has been phenomenal, with over a hundred patents filed just in 2015. However, a large chunk of these patents are coming from a few departments. Here's a look at the number of patents filed by each department, over the years, since 2005:

Circle area denotes the number of patents filed in year x by department y

Most of the larger circles are clearly concentrated among the Electrical and Mechanical departments. The difference has been more stark in recent years. In fact, the top 4 departments (Elec, Mech, Bio, Chemistry) together contribute 65% of all the patents filed by IITB!  To some extent this is because of the nature of the work done in each department - certain departments tend to focus more on product-centric output, while others lean towards theoretical research.
It can also be seen that while certain departments have been ramping up the patent activity over the years, others are still producing these in bursts.

A surprising thing we noticed in our analysis was that the month of June sees almost twice as many patents filed as most other months! So the next time your guide tells you that students don't work hard over the summers, point them here ;)

Students Notice 'Student Notices'

20:09 Eeshan Malhotra 6 Comments

Every year, General Secretaries promise to outdo their predecessors in a number of aspects. While a lot of these claims are subjective, we found one place where GSes have objectively been besting the previous years’ marks pretty much every year - The number of emails sent on Student Notices. We managed to get a hold of every single email sent on Student Notices, and analysed them. Here's how the numbers stack up.

In the last academic year alone, the GSes sent the students a cumulative total of 1,085 emails! As you can notice (no pun intended), in recent years, the GS Sports has been topping the list. Now you know whom to blame when you run out of space in your inbox ;)

But say what you will, Student Notices is how we all stay informed about campus happenings throughout the year. We traced a typical student's events calendar using Student Notices. Cult, Sports and Tech broadly capture the events happening on campus. Here’s what last year looked like.

You can see the sharp dips during exam season, and the huge post-exam frustration-busting peaks right after. The spring semester, surprisingly has many more events than the autumn semester. In fact, March (typically near the end of a council’s tenure) sees more events than any other month, across all three domains.

Perhaps more interesting that when the emails are sent, is what the emails talk about. We picked out the most frequent words used by each GS, tenure by tenure.

After looking at a few of the clouds, you probably realized that student tops the list for most GSes. GS Cult and GS Sports typically send out more event-orientated emails, with high usage of words like time, venue, event. Turns out that GSHAs have been the most polite among all the GSes owing to the high frequency of please in their mails! You can play around with the app and discover your own fun(ny) trends. Let us know if we missed anything interesting.

The SN mailing list is a treasure trove for data-analysis, and we’ll keep bring you more insights over the next few weeks.

Peace yo!

Whether it's early in the morning, or late at night, it's undeniable that IIT Bombay runs on just one fuel: tea.

You probably have a favourite chai spot too, where the milk-to-water ratio is just right, and the hint of elaichi that the chaiwala adds makes all the difference. Some others amongst us are not so choosy. All that matters is to get a cup of tea to keep you awake, no matter where it's from.

So how far from tea are you in your hostel at any given time? What about when you're in your class? Your lab? We take a look at all the tea spots in the institute, and try to give you a visual insight (pun completely unintended) into how these are spaced out - in both location and time.

Here's a map of all the places you get tea in the institute. Every mess, canteen, and tapri included. By my count, there's a whopping 45 of them.

How many could you identify? (Don't worry, there's a labeled version coming right up)

But I'm more interested in knowing where I could sit and work, while still being within walking distance of a cup of tea. I'm lazy and I'd consider one minute of walking reasonable. Some of my friends will go up to 2 minutes. Anything more is for desperate times only. So here's an animated map of what's within walking distance of every tea stall that's pen at a given time.

It traverses through the hours of the day, and shades the area within walking distance of each tea spot.

At 8 in the morning, pretty much everyone is in their hostel, and most messes are serving tea. In just a couple of hours, the bulk of the attention shifts to the academic area. If you're a late waker, too bad. Around noon, the hostel canteens open up again. The academic area is still flush with tea for those who can't afford to take a break.

Late in the afternoon, at around 5 pm, the hostel area becomes the focus again, as students returning from labs and lectures enjoy a refreshing cup. Or three. At night, the academic area runs out of options entirely. Hostel canteens serve tea till reasonably late, till the blips start to go out one by one, and by 4 am, all you can hope for is that the tapri outside main gate is open. Sleep beckons, but IIT stays awake, watching the clock strike 5, then 6, and 7, till the messes open again at 8 and provide the much needed respite from a tea-less existence.

It's kind of hypnotic to watch the bubbles appear and disappear, and live through the day in one GIF. And now, as I wrap up this post at a healthy 4.30 am, it's time to decide whether to venture till the main gate, or stay up till the next glass of that sweet, sweet nectar becomes available in the morning.

As always, all the data and code is accessible on GitHub, for you to play around with.

1. The areas are circular because I've used aerial distances. While this is not the most accurate thing to do, it's a reasonable proxy. I used a walking speed of 5 km/hour,
2. The data was collected from a variety of sources, including the IITB website, Google Maps, and simply asking people we vaguely knew to be reliable sources of information. If we've made some inadvertent errors, let us know and we'll fix them.
3. The regular, non-exam-time, everyday timings have been used. In exceptional circumstances, some of these may not be open at the time we've indicated they will, or vice versa.
