ENHANCED ELECTRON TRANSIT TIME IN PINNED-BURRIED PHOTODETECTORS

ELECTRON TRANSPORT IN A MULTI-IMPLANT PINNED - BURRIED PHOTODETECTOR UNDER
UNIFORM ILLUMINATION CONDITION IS INVESTIGATED.A CHARGE TRANSFER MODEL
THAT COMBINES BOTH DIFFUSION EQUATION AND CONTUNITY EQUATIONS WAS
DEVELOPED TO ESTIMATE THE CHARGE READ OUT TIME IN THE PHOTODETECTOR USED
IN ULTRA HIGH FRAME RATE IMAGE SENSORS.A MAXIMUM EFFECTIVE DIFFUSION
LENGTH WAS ASSIGNED TO EACH IMPLANTED REGIONS AFTER TAKING IN TO ACCOUT
THE FRINGING FIELD DRIFT DUE TO MULTIPLE IMPLANTS.IT WAS ASSUMED THAT THE
CHARGE ON EACH SECTION IS DIRECTLY PROPOTIONAL TO ITS AREA UNDER UNIFORM
ILLUMINATION .THE TOTAL CHARGE AS A FUNCTION OF TIME IS OBTAINED AS A
SUPERPOSITION OF CHARGE CONTRIBUTION OF ALL IMPLANTED REGIONS.DIFFERENT
ELECTRON MOBILITY VALUES FOR EACH DOPING CONCENTRATIONS WERE CONSIDERED TO
ESTIMATE THE TOTAL CHARGE READOUT TIME.THE MODEL SHOWED EXCELLENT MATCH
WITH THE EXPERIMENTAL RESULTS.

Tantalum coatings on gun steel

Coating of steel surface with tantalum can protect it from erosive and
corrosive wear. Such coatings can be deposited by the sputtering process,
in which ions of noble gas, such as argon, transfer atoms from the target
(tantalum) to steel substrate in vacuum. The equipment for this process
has been built in the Ion Beam and Thin Film Laboratory under the
Sustainable Green Manufacturing program at NJIT. US Army is interested in
replacing chromium coatings inside gun barrels with tantalum, which better
protects the gun barrel surface. Processing and recycling of chromium
generates hazardous waste and the success of the new coating technology
will have a positive environmental impact.  Tantalum coatings with
excellent properties, which have been obtained at NJIT, are now tested at
US Army research laboratories, which collaborate on this research. This
work is a part of doctoral thesis with the ECE department at NJIT.

THREE DIMENSIONAL SURFACE WARPING FOR PLASTIC SURGERY PLANNING

This paper proposes to use free-form deformation for pre-surgical planning
in plastic surgery. 3D data is obtained with a stereoscopic method.  A
direct manipulation method is applied in order that surgeons are not
required to consider the underlying B-spline control lattice during their
use. The proposed method sets several parameters that can be altered to
meet different requirements.  One displacement vector can be adjusted to
different direction and length. Lattice resolution is set to change the
surgery surface area. To achieve a desired 3D surface warping result, an
arbitrary number of displacement vectors each with different direction and
length can be applied. The proposed method provides flexibility and
real-time effect. The volume change is specified during the warping
process. The work also proposes one simplified skin-muscle model and
simulates the implanted material needed to achieve the result. Graphical
user interface is developed and the nose augmentation as an example
application is presented and discussed.

BOOLEAN FUNCTION SIMPLIFICATION ON A PALM-BASED ENVIRONMENT

This project studies the problem of minimizing Boolean expressions and
provides an optimal implementation to this problem. There are many
benefits to simplifying the Boolean function before it is implemented in
hardware. A reduced number of gates considerably decreases the cost of the
hardware, reduces the heat generated by the chip and, most importantly,
increases speed. The algorithm follows the Karnaugh map looping approach.
For the implementation C++ coding was used on the CodeWarrior for Palm
Operating System environment. The object-oriented approach was used to
make the overall implementation efficient. This application brings
together the power of the algorithm and the convenience of the Palm
Handheld device for students, academics and digital circuit designers. Two
examples are presented to illustrate the efficiency of the proposed
algorithm.

GUI Design Advances

Though not an extensively public topic, proper GUI Design is an integral
part of software development in today's world. Starting from a brief
history of the GUI in software applications, the presentation will
continue on towards focusing on the GUIs of major OS's (current and
future).  The presentation also covers the new interfaces being used in
handheld computers, home appliances and public display systems. While
equal importance is given to PC and appliance interfaces, a distinct
contrast is still maintained on the roles the GUI plays in each setting.
Descriptive references to good/bad GUI design elements and GUI
enhancements in existing systems are explained with photographic
proof/examples. This presentation concludes with thoughts about GUI design
having just blossomed or whether the evil standardizing word is already
killing innovation.

Voice Recognizable FM Receiver

Neural Networks have been developed for over fifty years; however, it has
made its greatest strides over the past fifteen years with the wider use
of computers.  Speech recognition technology specifically has benefited
greatly from this.  As the speed of computers has increased so has the
ability of speech recognition to process the voice signals in a reasonable
amount of time.  This technology had led to many modern day innovations
such as security, and voice control.  In my project I will use neural
network technology to create a voice controlled FM radio.  I will train a
voice recognition chip to work with a FM receiver.  The user will be able
to turn the radio on and off, increase and decrease its volume, and tune
stations by means of voice commands.  Ultimately this technology can be
used in a car where the driver will not have to take his hands off the
wheel to adjust the radio.

Short Term Adaptatation of Disparity Vergence: A Suppressive Stimulus Study

Everyday, adaptation occurs as our nervous systems examines and fine-tunes
the correlation between sensory input and motor output. An example of a
system that displays adaptation is disparity vergence, which is the inward
or outward turning of the eyes. Vergence eye movements exhibit two key
behaviors, high velocities and accuracy.  The Dual Mode Theory depicts
these behaviors by modeling the system using two control strategies.  The
fusion sustaining component accounts for the high speeds and performs
coarse adjustments through open-loop control.  The fusion sustaining
component accounts for the high accuracy using fine tuning through a
feedback control mechanism. This study analyzed adaptive effects of the
vergence system using an infrared limbus tracking device to record eye
movements.  Specifically this study investigated how small steps of 1
degree influence 4, and 8 degree steps.  Adaptation was observed in the
two subjects studied.
