1. Dog Vaccinations and Quarantine: A Mathematical Approach on Rabies

Presenters: Vince Campo and John Palacios

The talk presents a model of the spread of the deadly disease rabies. Using data based

in China, the employed mathematical model describes the dynamics of the disease and

proposes a model to help better understand how the disease is spread. By utilizing

game theory the talk offers a strategy for individual dog owners on separate methods of

battling rabies, including vaccine and quarantine.

 

2. Evaluating Typhoon Haiyan’s Performance and Identifying Storm Surge Prone

Areas in Key Locations Across the Philippines Using Advanced Circulation

(ADCIRC) Model

Presenter: Nilo Espinoza

Typhoon Haiyan (2013) was one of the most catastrophic natural disasters on record in

the Philipines. The Advanced Circulation (ADCIRC) numerical model is used to hindcast

and evaluate Typhoon Haiyan. Three synthetic typhoons are created to identify storm

surge prone areas. Results from the simulations showed the relationship between

Typhoon Haiyan’s characteristics in the generation of storm surge. This research is

intended to assess the performance of ADCIRC to be used in predicting storm surge

from typhoons in the future.

 

3. Evaluating the Cost of Crowdsourced Computer Vision Data

Presenter: Gabrielle Aguilar

Analyzing the trade-off between informative data and the higher costs of crowdsourcing.

 

4. Analyzing Rota virus Vaccination using Game Theory

Presenters: Jacob Aquiningoc, Robert Babac, and Jayson Morales

Rotavirus is a highly contagious virus that causes severe diarrhea in young children and

is spread through the fecal-oral route. Two vaccines, Rotarix (RV1) and a neonatal

vaccine (RV3-BB) have been shown to be effective in decreasing the occurrence of

severe gastroenteritis disease. We analyze the transmission of rotavirus through a

mathematical model and construct a game theoretical model to determine the optimal

vaccination policy.

 

5. Digital “entropy” as an invariant under a refinement ofthe partition of the interval

Presenter: Dr. Yoshifumi Takenouchi

Dynamical systems are investigated through a mapping of an interval to itself. Repeatedly

applying the mapping, we obtain a dynamical system described by a piecewise linear map,

a corresponding permutation and an induced directed graph. By the characteristic polynomial

of the adjacency matrix a ternary number called digital“entropy” is defined. The talk will focus

on what happens when the partition of the interval is refined. It is proved that the digital

“entropy” remains invariant! Further results will be outlined. The talk will give the audience a

unique insight into dynamical systems from one of the experts!
