Some Projects and Experiences in
more detail
Quantum Dot HFETs:
HFETs (Heterojunction FETs ) are some kind of FETs that have been made of some
crystals with different bandgap e.g. AlGaN/GaN, AlGaAs/GaAs (They are also
called HEMT, MODFET, etc). Here we investigate properties of HFETs, which a
layers of self-assembled Quantum Dots have been inserted in their structure.

Quantum Communication: In my MScthesis I have investigated "Quantum
Communication". The abstract of my thesis is:
“We will investigate Quantum Communication. We will introduce necessary
definitions and quantities and investigate their properties.
Despite
some basic definitions defined in similarity with classical communication, we
will work with some issues that have quite quantum nature and not any
counterpart could be found in classical world for
them. Among these properties are indistinguishability
of quantum states and entanglement.
Altogether,
Quantum communication could be divided in three major
parts:
1- Compression of quantum information that means representing outputs of
a quantum source by using fewer resources which is possible by applying
“typical subspaces” concept.
2- Sending classical information through quantum channel. In this kind of communicationindistinguishability of quantum states reduces
channel capacity. For achieving capacity of channel, we use block coding, and
in decoding side we apply an observation, which does measurement simultaneously
(entangled observation) on entire of block.
3- Transmitting quantum information via noisy quantum channel. Here we are interested in sending
some quantum states with least deviation. For achieving channel capacity, we
use extended Hilbert Spaces and should not restrict quantum states to product
states.”

Communication Complexity: Theory of Holevo
mentions that we can't send more than N bit of
information by use of N qubit. But in this investigation we see that we can reduce
communication complexity in some problems by use of Entangled States. Also we see a practical scheme in which by use of a
flying photon we can reduce communication complexity.

Developing a PC cluster: In a 2-person group, we have
implemented a PC cluster from scratch. This cluster is been used for our simulation
purposes. Operating system is Linux, we use MPICH and FFTW library.
Simulation: We have written a program for
simulating Cavity Solitons. We have used "split steps" method
for solving Maxwell-Bloch equation. We wrote these programs at first in Matlab
software, for checking the integrity of the algorithms and programs. After than we rewrote the program in C language for achieving
higher speeds. In the next step we
modified the program to a parallel program which was executable in the PC
cluster.
Cavity Solitons: Here we investigate equation
related to forming Cavity Solitons.

Some Electronic and Programming
Projects
Software, Image Processing: My project for obtaining BSc degree was writing a program which was able to
process images and to identify them by extracting features of that image
and using that features in a Neural Network. I wrote this program in C
programming language in C Borland builder environment. The program at
first changes the picture to a black and white picture. Then it computes
some moments of image array. Next, these moments are fed
into a Neural Network.I defended
my project it with score 19/20
Software, Visual controller of
a Mobile Robot:
In a robotic group(Robodeminer Competitions,
Amirkabir University, Iran, 2002)
I was responsible for writing programs for controlling a Mobile Robot by
computer. I wrote the program in Matlab environment. The program was
consisted of two parts, Image processing and controlling the robot. In the
image processing part, the program captures the frames produced by camera
and by doing some operations on the picture (Edge Detection, Dilation,
Subtraction, Motion detection,...) detects the robot in the field. in the second part the program sends the necessary
commands to robot through SerialPort to the hardware
that is attached to this port. We won the third place in the RoboDeminer Competitions
with this robot
Electronic design, PLC (Power
Line Carrier): I
have designed and made a system that can send commands and information
through Power Line Cables. Advantage of using this system is that there is
no need to a new wiring in the building. Everyone can easily plug the
Sender and Receiver into the wall socket and control any electrical device
remotely or send and receive information like voice or anything else. This
is done by modulating information and commands by
a carrying wave.
Electronic design, Laser
Transmitter and Receiver: By this device we can easily send and transmit any information to
long distances. Information is carried by a Laser beam.
Here information is modulated by laser beam.
Electronic design, Telephone
Line Monitoring System: This project is a mixture of Software, Hardware (Computer Interfacing,
Digital and Analog). This device is been attached to telephone line, it is
capable of collecting Caller IDs, duration of calls, Time, etc. It stores
information and delivers it to PC.
Electronic design, Precession
table: It is a
CNC with one degree of freedom. It is designed
for using in the Laser Lab of university
of Azerbaijan for
Z-scan purposes.
Software, Controller of a
network of Microcontrollers and Database: It is software which
has been written in Delphi programming
language environment. It is consisted of two parts, one part is a
controller of a network of Microcontrollers and second part is a Database
that collects and manages the data that has been
acquired from Microcontrollers.
