Smart City utility providing - summer 2019

• Python and C++ programing for detection leakage and burst in pipeline. In this project, the sudden pressure decreases which are detected by several pressure sensors are used to find the location of leakage on pipeline. Signal analysis, Anomaly detection, Machine learning, Python Programming.

Machine Learning Signal and Image Processing, to distinguish Amino Acids sequences in proteins using Nano-pore sequencing techniques Start Spring 2018

• Ultra-sensitive probe to detect the amino acids sequence in proteins by using ion conductance microscopy. The results include the electrical signals caring the information of type of amino acids such as volume, hydrophobicity, charge, and polarity. Big data analysis in combination with computational signal processing and Time series analysis are required for reading information, classifying date, and predication of amino acids.

• 3D image processing using confocal Microscope images to track cancer cell invasion capillary and Nanotube. 3D de- convolution of microscope image to detect the configuration of nanoparticles (200nm – 350nm) in an optical trap. Image Processing and Machine Learning

• Firebrand phenomenon is known as one of the most important mechanisms in fire spreading. In this project, a very large sample size (60 thousand) of different properties of firebrands were provided and analyzed with machine learning technique and image processing. With machine learning, an artificial neural network employed to predict the mass of firebrands from the available data. In addition, in image processing stage, MATLAB code was employed to calculate the cross-section areas of photographed firebrands.

Statistical Analysis of Weathering Effects on Fire Retardant Coating,

• This project centered around the weathering effects on the performance of fire-retardant coatings. The statistical method of Analysis of Variance was employed using MATLAB. The weathering and type of coatings were considered as treatments and combustion properties of the samples as response to the treatments. At conclusion, the effectiveness of treatments on response variables were statistically determined. Molecular Dynamic Simulation of the Motion of Particles in vibrating box, Mechanical Engineering and Engineering Science Department UNC Charlotte Fall 2015

• In this project, the motion of the particles and their arrangement in the square vibrating box was simulated using the molecular dynamic (MD) concepts. This project defined to improve the performance of the Vibrating Polishing Machine in mechanical engineering department. (MATLAB)

Monte Carlo Simulation of Magnetic Ordering in the FCC Kagome Lattice Fall 2011

• The master’s project employed statistical methodology, specifically the Monte Carlo technique using HPC (High Performance Computing) on ACE net to investigate the magnetic materials used in GMR Sensors. FORTRAN and C++ coding plus Perl and Bash scripting were the main languages used in this project. The results have been published in Physical Review B journal. Simulation of Magnetic Properties of Ferromagnetic thin layer on semiconductor substrates Fall2005

• Computational simulation of magnetic properties of materials used in spin valves was a master’s project with the physics department. In this project, the DOS (Density of State) of several stable configurations of ferromagnetic atoms (Iron) over the semiconductor substrates (silicon) were investigated. The optimized configuration where the spin polarized orbitals of ferromagnetic atoms on Fermi level can survive in bonding process with silicon were considered as suitable candidate for spin valve in Spintronic applications. In this project, Quantum Espresso (http://www.quantum-espresso.org/), computational chemistry/physics software, was used.

Designing of precision machine & Instrumentation, Mechanical Engineering and Engineering Science Department UNC Charlotte Spring 2015

In this project, capacitive displacement sensors had been designed and manufactured to measure the displacement in sub millimeter scale. This team project was comprised of designing the mechanical and electrical parts, manufacturing, LabVIEW programming to voltage acquisition and calibration, and calibration stages. I had responsibility in designing and LabVIEW coding due to my experience in Instrumentation lab specially LabVIEW programming and electromechanical systems. Mini Project Spring 2013

The mechanical strength of Graphene has been investigated with SIESTA. This software package is used for electronic structure calculations and ab-initio molecular dynamics simulations of molecules and solids. (https://departments.icmab.es/leem/siesta/)
