The Myth of Icarus

Random Thought: The Myth of Icarus

In Greek mythology there is a tragic story of a man who flew too high and fell down:

Daedalus and his son Icarus were imprisoned inside a massive labrynth in Crete. The father made them each a pair of wings, and with these they were able to escape. Daedalus warned his son, “Don’t fly too high or the sun will melt the wax on your wings and you will fall. Follow me closely. Do not set your own course.” But Icarus became so exhilarated by his ability to fly, he forgot the warning and followed his own course instead. He flew too high, the wax melted, and Icarus fell down into the sea and drowned.

Recently, I felt like Icarus ...

3rd International Conference on Scientific Computing and Partial Differential Equations (Hong Kong)

The Third International Conference on Scientific Computing and Partial Differential Equations
December 8-12, 2008

Hong Kong Baptist University, Hong Kong


It is our intention to organize a well respected international conference series on Scientific Computing and Partial Differential Equations in Hong Kong. The first of this conference series was held in December 2002 and the second conference was held in September 2005. More details about these conferences can be viewed at and

Both conferences were held at the Hong Kong Baptist University, well attended by international experts in respective disciplines and were found highly successful in providing a forum for the exchange of ideas, and latest results within a multi-disciplinary setting. Many top scientists in the area of scientific computing, including Academicians from America, Europe and China, attended the conferences and presented their research results. A conference proceeding for the first conference was published in American Mathematical Society's Contemporary Mathematics series, a prestigious volume series of AMS. The second conference proceeding was published in Science Press series, a specialized publisher for such conference proceedings.


The Third International Conference on Scientific Computing and Partial Differential Equations series aims to promote research interests in scientific computation. We would like to review recent scientific developments and to explore exciting new directions in scientific computing and partial differential equations for time-dependent problems and its interaction with other fields.
There have been very rapid developments of Scientific Computing in Hong Kong, in part due to the research carried out within the Mathematics Department at the Hong Kong Baptist University, and increasing interest from sister departments in other higher education institutions in Hong Kong. As Hong Kong transforms herself into a high-tech industrial region, the need for scientific computing will rise dramatically, as scientific computing is commonly acknowledged to provide a third arm to research; the other arms being theoretical and experimental techniques.

Seminar on Boundary Noise in Scalar Transport and Diffusion Equations with Applications in Biology and Biomedicine

The Ateneo de Manila University Department of Biology, Department of Mathematics, and the DOST Balik Scientist Program

cordially invites everyone to a seminar entitled

"Boundary Noise in the Scalar Transport and Diffusion Equations: with Applications in Biology and Biomedicine"


Vena Pearl A. Bongolan Walsh, Ph.D.
Ellis College, New York Institute of Technology
Friday, July 25, 20083:30-4:30 PM
Ching Tan Room (SOM 111)
John Gokongwei School of Management
Ateneo de Manila University


Noise in boundary conditions is an important and intriguing question to consider, since it could represent uncertainties that occur naturally, like the salinity flux of denser waters from the Mediterranean entering the relatively fresher North Atlantic via the Strait of Gibraltar, which has been observed to vary seasonally; or to mimic the nature of ventricles in the human brain as being imperfect sinks for drugs directly injected into the brain tissues.We start with modeling an ocean gravity current, from the primitive Navier-Stokes and Energy equations, to current research on the scalar transport equation evolving with noise in the boundary.

We then discuss possible applications in drug-delivery to the brain, photo-transduction and the formation of thrombi.

What I forgot to Bring in France

Note: In a previous blog entry () I made a checklist of what I need to bring for my trip to France in ( on July 2008.

While in France I realized that I forgot to bring a very important item with me - a universal adaptor for my laptop and cellphone charger. Luckily, my digital camera charger is suitable for use in France. I realized that not all hotels in France have adaptors that can be lent to guests. I was able to buy an adaptor in an electronic shop in Lyon (called FNAC) but it was during the day before my last stay in France :(

Next time, I should put the adaptor in my travel checklist ...

in Lyon, France

Updates From France

Note: I've been traveling in France for about two weeks already. I've been busy with meetings and moving around, and I have not updated my blog (Raffy's World).

I arrived in Paris, France on July 10, 2008 to attend our last ONCO-MEDIA ( project meeting in LIP6, University of Paris 6. The other places that I visited in France include Versailles, Rouen, Dieppe, and Lyon. In Lyon, I visited CREATIS (one of our ONCO-MEDIA partners) in the University of Lyon and met with its director Dr. Hughes Benoit and research engineer Ms. Sorina Camarasu. I was supposed to attend another meeting in Edinburgh, Scotland, United Kingdom (UK) but I did not have enough time to get a visa to the UK before I left Manila so I was not able to attend the meeting in Edinburgh.

I am now in Lyon, France. In a few hours I will take a fast train (TGV) from Lyon Part Dieu Gare (train) station which will bring me to Paris Charles De Gaul (CDG) airport where I will take an Air France flight to Amsterdam, Netherlands. From Amsterdam I will take a KLM flight to Manila.

I am scheduled to arrive in Manila on Wednesday, July 23, 2008.

Figure Caption: Train Map of Metropolitan Paris. One of the maps that I will bring during my trip to Paris, France on July 10, 2008.

Today (9 July 2008) I spent most of my time preparing for my trip to Paris, France tomorrow morning.

Before my classes (Ma 20 and AMC 124) I went to the bank to ensure that I have sufficient money left in my checking account and to exchange some Philippine pesos to U.S. dollars.

I met my classes from 11:30 a.m. to 1:30 p.m. After my classes I checked-in online via KLM website. It was my first time to use the online check-in facility of KLM. My seat number is 42 K (window seat).

Here's my checklist for my flight to Paris, France tomorrow:

1. Passport
2. Plane ticket
3. Cash (for travel tax, terminal fee, and spending money)
4. Credit cards
5. Luggage (with clothes, toiletries, etc.)
6. Conference presentation
7. Camera (plus accessories)
8. Hotel voucher
9. Travel insurance
10. Laptop computer (with charger)
11. USB memory sticks
12. Maps
13. Cellphone (with charger)

Celebrator or Celebrant? Happy Birthday Jocelyn, Butch and Carlo (PSHS Alumni Association)

. Photo Caption: Shown in photo are some of the PSHS Alumni Association Board of Directors who were present during its monthly meeting held on 8 7 July 2008 in Kabisera Restaurant, Fort Bonifacio, Taguig City. From the photo collection of Raffy Saldaña (

Yesterday (7 July 2008) the Philippine Science High School Alumni Association Board of Directors met at Kabisera Restaurant, Fort Bonifacio, Taguig City for its monthly Board of Directors meeting.

Thanks to Jocelyn (Sanchez-Mendoza), Butch (Zaldarriaga) and Carlo (Subido) for the wonderful Filipino dinner treat. (Jocelyn, Butch and Carlo are the birthday celebrators for the month of July).

HAPPY BIRTHDAY Jocelyn, Butch and Carlo! We wish you many happy returns... Goodluck, Good health, and God Bless!

Note: One of the pre-meeting discussions focused (OR focussed) on the difference between a celebrant and a celebrator :) . One English expert in the group pointed out that the proper usage should be "birthday celebrator" and not "birthday celebrant."

Today I searched Google and this is what I found:

"The American Heritage dictionary says: cel·e·brant (sµl“…-br…nt) n. 1. a. A person who participates in a religious ceremony or rite. b. The priest officiating at the celebration of the Eucharist. 2. A participant in a celebration.

USAGE NOTE: Strictly speaking, celebrant should be reserved for an official participant in a religious ceremony or rite. In an earlier survey, however, a majority of the Usage Panel accepted the use of celebrant to mean “a participant in a celebration” (as in New Year's Eve celebrants). In this more general sense, celebrator is an undisputed alternative.

The following PSHS (Pisay) Board Members and Alumni Guests were present at the meeting yesterday (7/7/08):

1. Pio Esguerra (Batch 2003)
2. Joyce Simpas (Batch '92)
3. Raffy Saldaña (Batch '77)
4. Tina Jardiolin (Batch '84)

Talk on Soliton Theory


What: Special Lecture on SOLITON THEORY

When: Monday, 14 July 2008, 4:30 - 6:00 p.m.

Where: Ateneo de Manila University
(Room TBA)

Guest Speaker: Prof. Mikhail Kovalyov
Professor of Mathematics
University of Alberta


Prof. Mikhail Kovalyov will talk about some work in Soliton Theory. Solitons are stable formations of nonlinear systems some of which might be described by PDEs, integral equations, graphs, etc. Many "soliton equations" describe motions of fluids and find a great deal of applications in the description of water waves and atmospheric waves e.g. tsunami and rogue waves.Prof. Mikhail Kovalyov is a professor of Mathematics at the University of Alberta, Canada. He obtained his PhD in Mathematics from the Courant Institute of Mathematical Sciences at New York University. He was in Ateneo, as a visiting professor, in 1993-1994. And it was at this time when he started working on the theory of solitons.

Photo taken on April 23, 2008.

The School of Science and Engineering of Ateneo de Manila University is now part of a European Commission funded project on grid computing. Called “EUAsiaGrid - Towards a Common e-Science Infrastructure for the European and Asian Grids,” the project is an international research collaboration involving 15 institutions from Europe, Asia and Australia.

The EUAsiaGrid project contributes to the aims of the EU Research Infrastructure FP7 Program by promoting international interoperation between similar infrastructures with the aim of reinforcing the global relevance and impact of European e-Infrastructure.

The project's main goal is to pave the way towards an Asian e-Science Grid Infrastructure, in synergy with the other European Grid initiatives in Asia, namely EGEE-III via its Asia Federation, and both the EUChinaGRID and EU-IndiaGRID projects and their eventual follow on efforts.

Taking advantage of the existing global Grid technologies, with the specific emphasis on the European experience with the gLite middleware and applications running on top of it, the project plans to to encourage federating approaches across scientific disciplines and communities.

EUAsiaGrid will act as a support action, aiming to define and implement a policy to promote the gLite middleware developed within the EU EGEE project across Asian countries. Its main actions will be to spread dissemination, provide training, support scientific applications and monitor the results.

Aside from Ateneo de Manila University, the project consortium includes the following institutions:

1. Instituto Nazionale di Fisica Nucleare (Italy)
2. CESNET, z.s.p.p. (Czhech Republic)
3. University of Manchester (United Kingdom)
4. HEALTHGRID (France)
5. The Australian National University (Australia)
6. Academica Sinica (Taiwan)
7. Advanced Science and Technology Institute (Philippines)
8. Hydro and Agro Informatics Institute (Thailand)
9. Infocomm Development Authority (Singapore)
10. Ho Chi Minh City Institute of Information Technology (Vietnam)
11. Institute of Technology of Bandung (Indonesia)
12. National Electronics and Computer Technology Center (Thailand)
13. Universiti Putra Malaysia (Malaysia)
14. MIMOS Berhard (Malaysia)

The over-all project leader for EUASiaGrid is Dr. Marco Paganoni of the Instituto Nazional di Fisica Nucleare, Milan, Italy while the project leader for Ateneo de Manila University is Dr. Rafael Saldaña, Associate professor in the Mathematics Department.

Dr. Saldaña together with Mr. Allan Espinosa, faculty (on-leave) of the Electronics, Communications and Computer Engineering (ECCE) Department attended the EUAsiaGrid Project Launch and the International Symposium on Grid Computing on September 7 - 11, 2008 in Academia Sinica, Taipei, Taiwan.

Ateneo's Role in the Project

Ateneo de Manila University (AdMU) will be involved and contribute in WP3 (Support of Scientific Applications) and WP5 (Training). The Ateneo de Manila University partners will be involved in the subtasks: (1) Computational Chemistry/Bioinformatics and (2) Mitigation of Natural Disasters.

The Philippines is rich in natural products. There are active researchers in AdMU who are conducting molecular dynamics (MD) simulation of natural products such as carrageenan and indigenous plants with potential medicinal uses. AdMU's researchers intend to use grid computing technology to enhance the studies (MD simulations and bioinformatics aspects) of natural products.

The Philippines is also abundant in natural disasters: earthquakes, floods, volcano eruptions, landslides, etc. There are researchers in AdMU engaged in landslide modeling and simulation, climate change studies, and mitigation of natural disasters such as landslides, lahar flow, and volcano eruptions. Using grid computing technology our researchers intend to establish international collaborations towards building data grids on natural disaster mitigation and to utilize grid computing technology for modeling and simulation of natural disasters.

The Grid and High-Performance Computing Group of AdMU led by Dr. Rafael Saldaña has conducted training programs in the past in the area of high performance computing and computational science. AdMU will be involved in the Training subtask (WP5) and is aiming to conduct a national workshop on the benefits of and best practices in the usage of Grid Computing Technology, particularly in the fields of biomedical computing/bioinformatics/computational chemistry and mitigation of natural disasters, as part of the promotion of the proposed EU-Asia Grid infrastructure.

In addition to the EUAsiaGrid project, the School of Science and Engineering is also involved in ONCO-MEDIA (an international project funded by the ICT Asia Regional Program of the French government) and the Philippine e-Science Grid project of the Department of Science and Technology Advanced Science and Technology Institute (DOST-ASTI).

Is This Dementia? (A Funny Thing Happened To Me On My Way To The Forum)

This is not about the broadway play nor the film, "A Funny Thing Happened on the Way to the Forum."

I just want to have a "catchy" subtitle for this blog entry...

Earlier today ( 2 July 2008) I went to Leong Hall (the new Social Science building in campus) to attend the Environmental Leadership Forum. When I reached the hall I was surprised to see a different event going on, not a forum. I thought that perhaps I went to the wrong venue. Later, when I rechecked my invitation (I did not bring it along with me earlier), I realized that the forum was scheduled on July 3 and not July 2. I was correct about the venue but I was wrong about the date.

When I reflected on what happened I began to have a scary thought. Am I having a case of "dementia"?

Or is this just a case of watching too much "Dr. House" on tv?

I am not a medical doctor but I deal with biomedical-related research, particularly in computing and medical informatics.

My first instinct was to look into an online encyclopedia like Wikipedia and search for introductory information.

Here are some information that I gathered from a Wikipedia article on dementia:

1. Dementia (from Latin de- "apart, away" + mens (genitive mentis) "mind") is the progressive decline in cognitive function due to damage or disease in the brain beyond what might be expected from normal aging.

2. Although dementia is far more common in the
geriatric population, it may occur in any stage of adulthood. This age cutoff is defining, as similar sets of symptoms due to organic brain dysfunction are given different names in populations younger than adulthood (see, for instance, developmental disorders).

3. Dementia is a non-specific illness
syndrome (set of symptoms) in which affected areas of cognition may be memory, attention, language, and problem solving. Higher mental functions are affected first in the process. Especially in the later stages of the condition, affected persons may be disoriented in time (not knowing what day of the week, day of the month, month, or even what year it is), in place (not knowing where they are), and in person (not knowing who they are).

4. Symptoms of dementia can be classified as either reversible or irreversible, depending upon the
etiology of the disease. Less than 10 percent of cases of dementia are due to causes which may presently be reversed with treatment. Causes include many different specific disease processes, in the same way that symptoms of organ dysfunction such as shortness of breath, jaundice, or pain are attributable to many etiologies. Without careful assessment of history, the short-term syndrome of delirium can easily be confused with dementia, because they have many symptoms in common. Some mental illnesses, including depression and psychosis, may also produce symptoms which must be differentiated from both delirium and dementia [1].

Reference: [1]
American Family Physician, March 1, 2003

Of course, the best way to confirm my speculation is for me to undergo medical examination and consult experts in the field.

So, am I just overreacting? Should I accept that the fact I am "aging" now and will soon enter another phase of life? Or is this just a case of "brain overload" (too much information processing)?

I know that it is an overreaction on my part but I'm just "thinking out loud."

And besides, I want to introduce the topic dementia in my blog :)

One thing I know for sure -- dementia is not funny.



Reminder: July 7, 2008 is Alternative Class Program Day in Ateneo de Manila University

MEMO TO: The Loyola Schools Community

FROM: Ma. Assunta C. Cuyegkeng
Vice President

SUBJECT: Alternative Class Program/INAF Day

The Ateneo Debate Society (ADS) is hosting the Australasian
Intervarsity Debate Championship. To assist ADS in their need to
provide venues for 150 matches for Monday, 7 July 2008, we have agreed
to hold the Alternative Class Program/INAF
Day on the same day.

First year students will be given the opportunity to observe the
debates and prepare for the annual Horacio de la Costa Cup, a debate
tournament among first year English classes. Further announcements
will be made by the Sanggunian ng mga Mag-aaral ng Ateneo, in
cooperation with the English Department.

The National Service Training Program-Plus (NSTP+), the Junior
EngagEment Program (JEEP), and the Pabaon will hold their plenary
sessions for all second, third, and fourth year students,
respectively. Details will be announced by the respective Program

Please be reminded that these three programs are part of the LS
Integrated Non-Academic Formation Program (INAF). Since INAF is
integral to Ateneo education, completion of the programs is needed to
be cleared for graduation.

The Alternative Class Program/INAF Day will replace regular
undergraduate classes from 7:30 a.m. to 6:00 p.m. Regular
undergraduate classes will resume at 6:00 p.m. Graduate classes will
proceed, as scheduled, for the whole day.

Thank you very much.

A Twitter, A Blogger, A Multiplier

Remember the phrase, "The butcher, the baker, the candlestick maker" from a nursery rhyme?

Well, I have a modern version of that phrase..."A Twitter, A Blogger, A Multiplier."

Twitter refers to the social networking software that is freely available on the Web/Internet or a person who has a Twitter account.

Blogger refers to someone who writes a blog (like me) using a blogging software like Blogspot (or Blogger).

Multiplier is my term for someone who uses the social networking software Multiply -- which is reportedly very popular among Filipinos.

Well, I am a Twitter, a Blogger, and a Multiplier.I also subscribe to other social networking softwares such as Facebook, LinkedIn, Plaxo Pulse, WYAN, MySpace, Friendster, etc...

Why do I subscribe to these free softwares?

One reason is curiosity.

I'm curious about the features of these software, their functionalities, design, appearance, usability, and other software engineering aspects. Many of my colleagues in computing/computer science also subscribe to several social networking softwares for the same reason that I mentioned.

Of course, it also helps to connect to family members, friends, former classmates, colleagues and other people (even strangers) through these various softwares.

And most of all, they are free.


Activities, 1 July 2008


Some of my activities today, 1 July 2008. Note: Click on the image to see a larger view.

Laboratory Exercise No. 4 (Ma195a15, Numerical Analysis): Mathematica and Bisection Method

For my class in Ma 195a15 (Seminar on Numerical Analysis) today (1 July 2008) I discussed the Secant Method and later I taught my students how to write a Mathematica loop construct using the While[] function. The example I gave is the Mathematica implementation of the Bisection Method. See figure above. (Note: Click on the image to see a larger view).

Use of Technology in Math: Plot of f(x), Limit of f(x)


Given the function f(x) = ( Absolute Value of (3x -1) )/(x -1), shown above is the graph of f(x) using the Mathematica command Plot[ ]. Notice that f(x) is undefined when x = 1 and the line x = 1 is a vertical asymptote. (Note: Click on the image to see a larger view.)

As x approaches 1 from the left, f(x) approaches negative infinity.

As x approaches 1 from the right, f(x) approaches positive infinity.

For a limit to exist, the limit from the left must be equal to the limit from the right.

Therefore, we can say that the limit of f(x) as x approaches 1 does not exist (DNE) .

Note: I gave a similar item to my Ma 20 (Calculus) class in their first long exam today (1 July 2008). The students do not have an access to a computer or a graphing calculator during the exam. But they have access to a scientific calculator. So the students have to plot f(x) by producing an x y table where y = f(x). For example, when x = 0, y = -1. This item is worth 10 points in the exam. There were 10 items with a total of 100 points.

(P.S. Thanks for the feedback/correction I received from Dr. Pablo Manastas.)
