Young Engineers Unite

This week our school held the 9th DLSU-Osaka University Academic Research Workshop and Symposium.  Engineering students from De La Salle University in Manila and Osaka University in Japan showcased and shared their researches in hopes to foster strong academe relationship and in advancing the research developments of each school.  I was fortunate to have my master’s thesis included in the list of presentations.  Below are some thoughts from the workshop.

The longer, the better

I presented my thesis entitled “On The Hardware Implementation Of Hard-decision-based Bit-flipping Algorithms For Low-density Parity-check Codes”.  If you think that was too long for a title, well, get a load of these research titles:  Baseline Sediment Oxygen Demand Measurement at Selected Stations in Pasig River Using a Bench-scale Benthic Respirometer;  A Java-based Finite-Difference Time Domain (FDTD) code in Designing Photonic Crystal Fiber (PCF) Waveguide for Terahertz (THz) Radiation Delivery;  Design and Development of a Standalone Potentio-Galvanostat for Electrochemical Deposition and its Application in the Fabrication of BSCCO Films;  A phenomenological Ginzburg-Landau model of the pressure dependence of the critical parameters in high-temperature superconductors.  How about that?

A long title would sound intimigating and complicated.  You might think that a short title can make things simplier and easily understood.  Well, try these short research titles:  A Family of Cusped Cubic Bézier Curves;  On the Bandwidth of Tower Graphs Tm,2 and Tm,3; A Generalization of T-Groups.  Do they sound simple now?

No wonder people will easily have an impression of engineers being nerds and geeks.

A Measure of Reliability

Part of every research is showing how effective or reliable your results are.  This will be a measure if your research is something that is successful and useful as you intend it to be.  One of the presentation was a research designed for doctors.  It saves X-ray images in a database for archiving.  However, once the x-ray images were converted to digital format using digital cameras, some details may be missed out especially on the shades of white of the x-ray image.  As a result, during the test of the system, 2 of the 3 doctors made the wrong interpretation on 2 of 46 stored x-ray images.  But they pointed out that there is 44/46 success rate or ~96%.

I mentioned that the 96% might not be acceptable and needs more data to secure its credibility.  Since we are dealing with people’s lives, we have to design systems that are close to perfection.  In a 99.9999% acccurate system, the 0.0001 imperfection can decide the life and death of the patient.

On the ligher side, the 96% is not that bad at all, at least for engineers.  It’s the doctors who interpret them.  Thus, if they made a wrong diagnosis because of a poorly designed system, the patients gets back at the doctors by filing a malpractice case while the engineers never gets the blame.  Life is never fair.

Makings of a Genius

One research paper caught my attention.  while I never got to attend the presentation, the title itself was enough to make me say “Wow, why haven’t I thought of this?”  His research was entitled “Detecting nudity in pictures”.  This is a very good study since its applications are definitely important when implemented.  It can automatically filter out inappropiate pictures in the internet.  This will be helpful for parents and institutions that are concerned on the welfare of children surfing unmoderatedly in the internet.  What a genuis!

While it sounds to be easy, the math and science behind its implementation must be very complicated.  Imagine all the variations when it comes to nudity:  color, body parts, exposure, size, positions and a lot more.  How will he put it all in the system so that the computer can easily detect that the picture is an inappropiate hot blonde amatuer showing off her front assets and not an innocent new born baby that is topless?  Both are showing nudity but we know which one is to be filtered.

I want to volunteer to evaluate his research.  When it comes to nudity, I am an expert.  what I mean is, I can still think objectively when science, math and nudity are rolled into one.  Take the number 69 for example.  See what I mean?



  1. brilliant jin… coz not a word is familiar to me in those reasearch titles but the last one… haha

    Im really inrested to attend the presentation. I wonder if there will be samples or demo. I would love to see those.

  2. hahahahahahaaha letme tell,my dear engineer friend, that as for numerical coefficients of nudity, there is 69 AND WELCOME 88! Ill 8 yours, and you’ll 8 mine! hahahahaha

    amazing studies bro. i hope yours will soar (although it is given, gavan!).hehehehe

    Bag-o na a. Gaga ka. Pang General Patronage ni tani nga post pro.

  3. jin, amo ka man ya gihapon no? ang seryoso, nadungangan guid sang la-in la-in? :), nice integration of technicalities and humor though. good luck to your research.

    Gina kadlaw ko lang ang libog ko a. Pero syempre naga enjoy man ko ubra thesis.
