Organic Search and Recommend System
Vinit Bhansali - 1st place, undergraduate catagory.

The idea behind an organic search and recommend system is to 
search through peer-data and intuitively calculate .best 
recommendation.. I apply a pattern-matching algorithm to search through 
primary data and match multi-user homogeneous data and generate a 
.recommended. list containing data found in common with other user 
data-sets that test positive for the primary data. This logic will be 
applied in designing a pattern matching algorithm that uses data-sets 
containing multiple homogeneous entries and generates results by 
applying each entry as a part of the whole set. My algorithm is 
different in that the resultant set contains data that relates to the 
query or is organically similar to the query. This system aims to 
reduce and eventually remove the problem of junk/non-homogeneous data 
that comes up using common search algorithms. Junk data often crowds 
out the real information that should have surfaced in the first place.

The Design, Simulation, Prototyping, and Testing of a Complete 
Microwave-Frequency Filter Assembly
Kanquor Hsiao, Cecylia Wati, Pyung Choi - 2nd place, undergraduate 
catagory.

Great interest in microwave frequencies has arisen for a 
variety of reasons.  Leading among these is the ever-increasing need 
for more radio-frequency-spectrum space and the rather unique uses to 
which microwave frequency circuits can be applied.  This growing 
industry has increased the demand for innovative filter designs that 
not only maximize performance, but also minimize size.  Our advisor, 
Dr. Edip Niver, and his team have developed an exciting new filter 
conception.  It makes use of cylindrical cavity resonators in order to 
minimize overall filter dimensions.  Our team of students is exploring 
the theory for this particular filter and optimizing our own design 
application of this filter in order to fall within a set of specified 
parameters.  The simulation of our design has been facilitated in 
Ansoft HFSS, a 3-D electromagnetic simulation software. Ultimately, 
this filter project will culminate in the construction of a working 
prototype that will be tested for real industry application.

Bandwidth Allocation over Ethernet PON
Yuanqiu Luo - 1st place, graduate catagory.

Ethernet Passive Optical Networks (EPONs) are being 
considered as a promising solution for the last mile access network. 
EPONs possess many attractive qualities such as low cost, simple 
maintenance, and ease of adding a new user. Our research investigates 
the bandwidth allocation issue in the upstream direction from the 
Optical Network Units (ONUs) to the Optical Line Terminal (OLT), 
purposing to effectively and efficiently allocation the time slots 
among the Optical Network Units (ONUs). Our proposal dynamically 
allocates the upstream bandwidth based on the number of already 
buffered packets and the number of predicted incoming packets. The 
simulations verify that our proposal outperforms other bandwidth 
allocation proposals in terms of the packet delay and the queue length.

Hot carrier reliability of MOSFETs
Purushothaman Srinivasan - 2nd place, graduate catagory.

In this paper, I have investigated the screening of hot 
carrier stress degradation in n-channel MOSFETs when the devices were 
exposed to plasma processing. Devices with various antenna ratios were 
subjected to current stress (both gate injection and substrate 
injection) while the source and drain terminals were reverse biased by 
a screening potential followed by hot carrier stress. It was observed 
that screening of the drain edge was effective for both gate injection 
and substrate injection at different screening potentials. The hot 
carrier lifetime is directly related to interface state density (Dit), 
measured by charge pumping method. The results suggest that hot 
electron degradation could be severe or mild for devices affected by 
plasma damage depending on their exposure to the level of screening 
potential.

A Multi-Paradigm Modeling Approach for Hybrid Dynamic Systems
Jin-Shyan Lee - 3rd place, graduate catagory.

In the past years, modeling and simulation of hybrid dynamic 
systems (HDS) have attracted much attention. However, since 
simultaneously dealing with the discrete and continuous variables is 
very difficult, most of the models result in a unified, but more 
complicated and unnatural format. Moreover, design engineers cannot be 
allowed to use their preferred domain models. Based on the 
multi-paradigm modeling (MPaM) concept, this paper proposed a Petri net 
(PN) framework with associated state equations to model the HDS. In the 
presented approach, modeling schemes of the hybrid systems are 
separated, but combined in a hierarchical way through specified 
interfaces. Designers can still work in their familiar domain-specific 
modeling paradigms and the heterogeneity is hidden when composing large 
systems. An application to a rapid thermal process (RTP) in 
semiconductor manufacturing is provided to demonstrate the 
practicability of the developed approach.
