Research Fields

Fractional-order systems and Applications

Fractional calculus is the branch of mathematics related to differentiation and integrations of non-integer orders where the conventional calculus is considered a special case from it. The study of fractional order domain can be categorized as follows:
Numerical techniques that are suitable for FODE and FPDE.
Stability analysis of LTI systems and applications
Generalized theorems related to several dynamical engineering systems.
Approximation techniques that mimic the behavior of these fractional order elements.

Chaotic Systems and Applications

Chaotic behavior is unpredictable due to the high sensitivity to initial conditions, model parameters, computer precision, and even numerical algorithm. Chaotic systems are pseudo-random as they are deterministic but show a very close behavior to random systems which can be used later on in Encryption and security applications.

Design and Applications of Mem-elements

Memristor was firstly introduced as the missing link between flux 𝜑 and charge 𝑞 by Chua in 1971. The importance of the fingerprints (FPs) for the memristive elements is the ability to identify the memristive nature of the system from experimental data. One of the most widely known FP for the mem-elements is the pinched hysteresis loop (PHL). Several research tracks are related to this topic such as neuromorphic systems, multi-level arithmetic systems, crossbar memory synthesis, … etc.

Bio-impedance for Food Quality

 The cell consists of intracellular fluid, cell membranes surrounded by the conductive extracellular fluid which show frequency dependent behavior under electrical excitation where a bio-impedance is produced. Bio-impedance refers to the electrical properties of a biological tissue which depends on tissue composition, structures, health status, and applied signal frequency. Different fractional-order models are used to extract some data from the vegetables/fruits like the EEG

Supercapacitors and Energy Storage Elements

Renewable energy sources provide a promising alternative to fossil fuel-based power generation as the latter is limited in quantity and is expected to be completely consumed sooner or later. Examples of renewable energy resources in Egypt include solar energy, wind energy, and hydro-electric energy. My work aims to study the effect of applying fractional order modeling techniques on supercapacitors and fabricated CPEs and how it will affect their efficiency, state of charge, state of health and other performance metrics.

Biomedical Engineering

The neuron is the basic cell of the brain, and its objective is to transfer information to other body cells. Recently, different research studies discussed the modeling of neuron types using different techniques. Modeling, synchronization, and implementation of neurons are some of my research interests. Also, Inverse problem using Electromagnetic waves can be used for the detection of breast cancer.

Wastewater Treatments

Wastewater treatment is the process of recycling wastewater to be reused. Egypt, as a developing country, although having the Nile River as the first and fundamental water source, it suffers from many issues in water distribution and water management. There are several types of reactors and therefore mathematical modeling of these reactors are very important to improve the efficiency.
