Finalist for "The Pitch"

John Darby H'14 was one of the four finalists this year for The Pitch, an annual contest where students develop and promote ideas for products or services. The final contest was held on Wednesday, March 12. The finalists competed for a $10,000 prize by presenting their projects to a panel of judges made up of four HWS alumni who have been successful in the business world. (The day of the pitch turned out to have some of the worst winter weather that Geneva has seen in years, but it went ahead as scheduled.)

John Darby is a double major in computer science and architecture and is a member of the HWS Sailing team. His idea for the pitch arose partly from an independent study that he did in web site programming. John will attend graduate school next year in the architecture program at the University of Pennsylvania.

The Stu Lieblein '90 Pitch was held for the third time this year. It was established to promote entrepreneurial leadership and is organized by the Centennial Center for Leadership of Hobart and William Smith Colleges.

Alex Kittelberger Honors Project

Alexander Kittelberger H'13 has completed an Honors project with the title, Online Virtual Math Museum: Building a Virtual Math Museum with Modern Web Technologies and an XML Infrastructure. An Honors project is a year-long endeavour culminating in a long Honors thesis and an oral examination by a committee of three examiners. Alex's Honors Project was to create a website for mathematical visualizations. From equations to geometry, there are many different types of mathematical objects that can all be described in different forms. The “Online Virtual Math Museum” is designed to store and present information about mathematical objects in the form of a website. An XML language is used to define these mathematical objects, and a Java program is used to create webpages to present the objects visually. For this project, a framework was developed for a website that can display different mathematical objects. The framework can easily be extended and allows programmers to expand on the presentations. Alex's advisor for the project was Professor David Eck.

Laser Tag in CPSC 336

Here is a picture from a "laser tag" project in Professor Vaughn's Robotics course (CPSC 336). The first project in that course in Spring 2013 was for each student to build and program a mobile robot to play laser tag. Each robot was equipped with a low power laser, laser detector, and infrared obstacle detector. Any robot hit by an opponent's laser was required to leave the arena. Each behavior-based robot was individually programmed with a strategy to apportion its limited power resources for lasers, movement, or general health. The contest was held in a darkened arena to maximize the laser effects.

Gionet Receives Fulbright Scholarship

Trevor Gionet (H'12) has been awarded a Fulbright English Teaching Assistantship for study in Vietnam. In addition to teaching English, Trevor will take Vietnamese language lessons focused on mathematics. With this, he hopes to be able to teach math bilingually.

The Fulbright Program was established by the U.S. Congress in 1946. The purpose of the Fulbright Program worldwide is "to increase mutual understanding between the people of the United States and the people of other countries by means of educational and cultural exchange." The U.S. State Department's Bureau of Educational & Cultural Affairs (ECA) is the principal administrator of the Fulbright Program. Bi-national commissions, composed equally of U.S. and partner-country citizens, coordinate Fulbright Programs in fifty-one of the 140 participating countries.

Yaoxin Liu Honors Project

Yaoxin Liu, H'12, has completed an Honors project titled, "A Mathematical Model: Hepatitis B and Hepatitis D Co-infection." An Honors project is a year-long endeavor culminating in a long Honors thesis and an oral examination by a committee of three examiners. Here is a description of his project: "In this honors project, mathematical models are developed to describe the interaction between human liver cells, hepatitis B virus (HBV) and hepatitis delta virus (HDV). HDV is a dependent virus that can only infect patients who are also HBV-infected, and it causes more severe damage to liver cells than HBV alone. This project is an extension of previous research, which focused on analyzing the impact of immune exhaustion on HBV and HDV infections. Shifting the emphasis to the dynamics of the infections, this honors project will shed light on what causes the severe damage to liver cells. Mathematical models of the system are built from a simpler model of a single infection and used to explore the possible outcomes of HBV and HDV co-infection. Computer simulations are also created to support analytical results. Manipulation the magnitude of different parameters has helped in understanding how different host and viral factors affect the severity of disease." Yaoxin's advisor on this project was Professor Jon Forde.

Marcela Melara Honors Project

Marcela Melara, WS'12, has completed an Honors project titled, "ELARA: Environmental Liaison and Automated Recycling Assistant." An Honors project is a year-long endeavor culminating in a long Honors thesis and an oral examination by a committee of three examiners. Here is a description of Marcela's project: "One environmental issue we face today is dealing with the large amounts of landfill garbage. While many efforts are already being made to increase recycling, many people still have trouble identifying and sorting recyclable materials. In order to improve this situation, I designed and built ELARA. This is a new system that facilitates recycling and waste sorting by helping people identify the items which are recyclable and those which are not. The most immediately noticeable aspect of ELARA is a networked kiosk to help users sort their waste correctly. The kiosk is the front end of a larger system of hardware and software." Marcela's advisor for this project was Professor John Vaughn.

Shaun Viguerie Honors Project

Shaun Viguerie H'12 has completed an Honors project entitled "ISTAT: Online Interface for Hypothesis Testing." An Honors project is a year-long endeavor that culminates with a long Honors thesis and an oral examination by a committee of three examiners. Here is a description of his project: "This honors project involved the creation of an online statistical software application (called ISTAT) for hypothesis testing. The package has a user-friendly interface, and is able to work with data from a variety of different sources. Designed for student use, it supports hypothesis tests commonly covered in introductory statistics courses. The core functionality of the application lies in JavaScript libraries, making it easily extendable. By utilizing many modern web technologies, the project demonstrates the improving capabilities of the web as a platform for complex applications." Shaun's advisor for this project was Professor David Eck.

A Mathematical Model of T Cell Exhaustion Caused by HBV/HDV

On Wednesday, November 9th at 4:30pm, Hobart Mathematics Major Yaoxin Liu '12 will discuss his summer research project in Napier 201. In patients with chronic hepatitis B infection, the immune system becomes exhausted, losing its effectiveness over time. Co-infection with another virus, Hepatitis Delta, reduces the amount of HBV in the blood, and so may relieve the exhaustion. During the Summer Research Program last summer, Yixiao Sha, Yaoxin Liu and Prof. Jonathan Forde developed an ordinary differential equation model of the interactions of these two viruses and the immune system to study the effect of a second infection on immune exhaustion. Sha, Liu and Forde started by studying the four dimensional model with only HBV infection, and then added the second virus, HDV. They also analyzed various steady states and their stability for both systems. All the stability conditions are found for the four dimensional system with only HBV infection. For the five dimensional system with HDV, numerical simulations show the existence of positive steady states representing chronic coinfection. The model suggests that co-infection does not reduce the exhaustion level, but increases damage due to general inflammation. (Refreshments will be served beforehand.)
