2005 SURF-IT Schedule
The Summer Undergraduate Research Fellowship Program in Information
Technology (SURF-IT) presents a four-part summer seminar series, featuring
faculty projects involving SURF-IT students. The program will conclude
with a poster session.
Speaker: William Tomlinson
Title: The Eco-Raft Project
Abstract: The goal of this project is to combine research in computer science, mobile computing, interactive animation and restoration ecology in order to develop a novel computational platform for environmental education. This platform will serve as the basis for regionally specific interactive exhibits that will be installed in science centers and museums around the United States. The interactive platform consists of a heterogeneous network of fixed and mobile computational systems, inhabited by autonomous animated agents (virtual species). This paradigm involves several stationary computer screens that serve as "virtual habitat patches" inhabited by small populations of the animated species, and several Tablet PCs that serve as "virtual rafts," or dispersal mechanisms, with which people carry the species from patch to patch. This project has already been accepted to the Emerging Technologies venue at SIGGRAPH 2005; a major mid-summer milestone will be to present the group's work at that conference.

Abstract: Our research program is developing new concepts and strategies at the interface with biology for the design of well-defined polymeric materials. This presentation will highlight our recent work on the synthesis and single molecule nanomechanical studies of new biomimetic modular multi-domain polymers. Inspiration from natural biopolymers is used in our lab to design macromolecular materials having precise secondary structures for advanced mechanical properties. Modular domain structures are commonly seen in natural biopolymers such as adhesion proteins and skeletal muscle protein, titin, which have important mechanical functions in biological systems. The remarkable combined strength and toughness of titin was proposed to derive from its modular structure comprising a linear array of domains, in which each domain is held together by secondary forces. We have synthesized titin-mimicking modular polymers having various supramolecular modules.
This talk will discuss the design principle, synthesis, single molecule studies, and correlation of single molecule and macroscopic mechanical properties of the modular polymer.

The Summer Undergraduate Research Fellowship Program in Information
Speaker: Jia Grace Lu
Abstract: In general, this project incorporates fundamental science and technological application of nanostructured materials, with the aim to build integrated nanoscale devices crucial for future information technology, fitting with the vision of Calit2. This work focuses particularly on the electrical, optical, magnetic and chemical sensing properties of individual single-crystal semiconducting nanowires, configured as field effect transistors. They demonstrate enhanced transistor property with large on-off ratio, strong polarization-dependent photoconductivity, and high sensitivity to toxic gases such as NO2, NH3, and CO. At present, we are working to obtain n-type and p-type metal-oxide nanowires with uniform electrical properties, and fabricating vertically aligned field effect transistors and logic gates in order to fully utilize the scaling advantage of these nanomaterials. In addition, magnetic doping in the nanowires is being explored to study low-dimension ferromagnetic ordering and to develop efficient spin injectors and spin transistors. The objectives of the student's project are to understand the effect of reduced dimensionality on the properties of semiconductors; and to design, create, and characterize coupled nanostructures.

Title: Fingerprint Data Collection and Analysis
Abstract: This talk will cover current controversies over the reliability of forensic fingerprint identification, focusing on the role that automated fingerprint identification systems are playing in this controversy and what role they might play in the future. The speaker will briefly discuss, and solicit comments on, research being carried out this summer using an automated fingerprint identification system.
SURF-IT Fellow: Robert Carpenter
Future seminars will be held August 9 and August 23.
Speaker: Kristen Monroe
Abstract: In general, this project studies the problem of what drives ethical treatment of others, can it be taught, and if so, how can we best do this. Literature on what causes ethical treatment of others traditionally offers 2 approaches: disposition versus situation. This project proposes a third route: phenotypic - multifaceted self, with diverse parts evoked by stimuli from external environment, e.g., friends, context.

Title: Channel modeling in wireless communication
Abstract: This talk will begin with a general discussion of wireless
communications and its different components, continuing with description of different impairments in wireless channels. It will show how one can
mathematically model the physical phenomenon's in a wireless channel and how to use these mathematical models to analyze and design wireless
communication systems. In conclusion, the speaker will briefly illustrate the implementation of these mathematical models using

The final SURF-IT seminar will be held August 23.
Speaker: Falko Kuester
Both projects are integrated into the Calit2 Center of GRAVITY
(Graphics, Visualization, and Imaging Technology), which includes
faculty from the departments of Electrical Engineering and Computer
Science, Earth System Science and Studio Art.
The objective of the "EPSS" project is to develop gaming technology for
the exploration and manipulation of environmental systems, using
scientifically accurate geophysical simulations. Such games would
provide an engaging means for large groups of people to collectively
learn the effects of various actions on the global environment. The EPSS-GE project work for this summer is focused on interacting with a
reduced model of geophysical forcing using the National Center for
Atmospheric Research (NCAR) Community Atmospheric Model (CAM). The team
is studying simulation and data exchange between UCI's Earth System
Modeling Facility, the game server grid, and user interfaces. We are
currently extending the functionality of a prototype by completing a
series of focused short term projects. The work includes integrating
earth system databases into existing game engines, designing and testing
new visualization techniques, analyzing geophysical models, and
developing intuitive feedback and interaction mechanisms. Effort is
also focused on studying the variety of ways scientific visualization
has already been used to demonstrate geophysical and temporal scales,
model interpretation and data exchange -- reviewing computer games such
as "SimEarth", movies such as "A Perfect Storm", and display interfaces
such as "Orb".

Abstract: Distributed Data Reduction and Analysis (DDRA) refers to the task of crunching datasets stored in separate physical or network spaces. DDRA has emerged as both an opportunity and chokepoint for collaborative research in high performance computing applications. For example, Climate simulations prepared for the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) reside on a distributed network of storage archives known as the Earth System Grid (ESG). I will describe how we use DDRA techniques to get the data from the ESG and use it to characterize the envelope of future Californian climate contained within these datasets. Our goals are two-fold: 1. To quantify the Californian climate expected under a variety of IPCC forcing scenarios; and 2. To benchmark, characterize, and reduce bottlenecks encountered in DDRA of geophysical datasets.
