Abstract-Tbe effects of temperature and current on the resistance of
small geometry silicided contact structures have been characterized
and modeled for the first time. Both, temperature and high current
induced self heating have been shown to cause contact resistance
lowering which can be significant in the performance of advanced ICS.
It is demonstrated that contact-resistance sensitivity to temperature
and current is controlled by the silicide thickness which influences the
nterface doping concentration, N. Behavior of W-plug and force-fill
(FF) Al plug contacts have been investigated in detail. A simple model
has been formulated which directly correlates contact resistance to
temperature and N. Furthermore, thermal impedance of these contact
structures have been extracted and a critical failure temperature
demonstrated that can be used to design robust contact structures.

Temperature and Current Effects on Small-Geometry-Contact Resistance
Friday, October 31st, 2008Finger mouse and text-to-speech application as additions to the smart wheelchair.
Friday, October 31st, 2008The smart wheelchair project is a unique investigation into the possibilities of
helping the impaired navigate in a mobile chair. Many disabled people who need the
help of a wheelchair to move about also need help communicating orally. My project
allows the “walking” wheelchair to do some “talking.” I developed the addition of a
communication program for the wheelchair as well as a finger mouse to be implemented
into all the programs. The finger mouse is a switch button small enough to wear on one’s finger. When the button is pressed, a signal is sent out from the transmitter and picked up by the receiver, which sends a signal through the parallel port of the computer to execute the desired application. The application I created is a speech program that speaks text messages. The finger mouse and speech application are connected through a communication display interface. The mouse, display, and speech software work together by speaking phrases when the mouse is clicked over the icon linked to that phrase. Thus the communication program gives the freedom of speech to anyone using the wheelchair for free range of motion

The effects of temperature variation on electron beams with RF voltage modulation
Friday, October 31st, 2008Abstract
The correlation between the horizontal beam size vs.
the cavity temperature, observed at the Taiwan Light
Source (TLS), is explained by the combined effects of (1)
cavity resonance frequency shift resulting from
temperature change, (2) cavity voltage and synchronous
phase angle change resulting from uncompensated beam
loading in the low-level rf-feedback system, and (3) rf
cavity voltage modulation for alleviating the coupled
bunch instability. This experimental method can be used
to evaluate the intrinsic resolution of the low-level rf-
feedback system.

The Effect of Temperature on Resistance
Friday, October 31st, 2008This project allows students to experimentally discover the temperature dependence of resistance using a copper wire, a standard 1 Ω resistor, and a piece of BSCCO 2223superconducting tape.Using liquid nitrogen as the refrigerant, students will measure electrical resistance over a temperature range from -196 °C (77 K) to room temperature, approximately 22 °C (295 K)

Temperature and Voltage Scaling Effects on Electrical Masking
Friday, October 31st, 2008Abstract— Radiation induced soft errors in combinational
logic is expected to become as important as directly induced
errors on memory elements. Recent works have looked at
modeling and estimating soft errors in logic circuits.
Increased power consumption with very dense circuits has led
to large number of hot spots in present day ICs. Voltage
scaling is one of the popular techniques used for power
reduction in circuits. This work presents the results from a
study of effects of both increased temperature and voltage
scaling on electrical masking effect in logic circuits.

Build a shaft encoder using parts you can salvage from dead computer mice
Friday, October 31st, 2008Equipment designers often find
that digital shaft encoders are
more expensive than they
would like. Encoders also may not be
available in the angular resolutions
they desire. Here is how I designed
and built a tuning knob for my com-
puter-controlled transceiver using
readily available components and a
little persistence.

Quantization of Wavelet Coefficients
Friday, October 31st, 2008“Adaptive Quantization of Wavelet Packet Coefficients for Embedding and Extraction of Digital Watermarks “:
Abstract—In this paper, a robust digital image watermarking
approach of embedding and extraction of digital watermarks using
adaptive quantization of wavelet packet coefficients was proposed.
The original image is decomposed by discrete wavelet packet
transform and the dominant wavelet coefficients are selected for
watermark embedding from each sub-band except the lowest
frequency one. Then, each watermark bit is adaptively embedded
with different strength into the selected wavelet packet coefficients
based on the odd or even value after quantization.

Geosynthetics for soil reinforcement
Friday, October 31st, 2008Abstract: This lecture introduces geosynthetic materials and briefly describes their types and manufacture, functions and applications, properties and tests, design, selection, and specifications. Geosynthetics for soil reinforcement are then discussed in some detail, with specific applications to embankments on soft
foundations, steep slopes, and for the backfills of retaining walls and abutments.
Emphasis is on the materials properties of the geosynthetics required for design and
construction.

Generating Test Patterns With TetraMAX ATPG
Friday, October 31st, 2008In this chapter, you will learn how to use TetraMAX ATPG to generate
test patterns as part of the DFT Compiler flow. This chapter contains
only a brief introduction to the TetraMAX tool, which has many
capabilities that are not covered in this chapter.
This chapter contains the following sections:
• Design Flow Without BSD Compiler
• Design Flow With BSD Compiler
