Faculty Office Ext.
Starting August 1st, 2021, Prof. Wael Akl has been appointed as the President and Acting Provost of Nile University. Prof. Akl has finished his Ph.D. from the Mechanical Engineering Department, University of Maryland-College Park in 2004 in the field of smart materials and ever since Dr. Akl has been engaged in research work in the field of smart materials and structures with over 48 international publications with a focus on Acoustic Metamaterials for the past 5 years. Prof. Akl has been granted a Research Faculty Fellow and visiting professor at the University of Maryland for 10 years in a row starting in 2006. Prof. Akl is the co-founder of the Group for Advanced Research in Dynamic Systems (The largest research group at Ain Shams University).
Starting 2008, Prof. Akl joined Nile University and ever since he has undertaken the responsibility for establishing the Mechanical Engineering track, where he has founded the Mechanical Engineering Undergraduate program in 2012, FESTO Authorized and Certified Training Center (FACT) in 2013, the Mechatronics Erasmus Joint Masters Program (EU4M) in 2014 and the Smart Engineering Systems Research Center (SESC) in 2017 at Nile University. In 2012, Prof. Akl was appointed program director for the Mechanical Engineering Program, and in 2016 he was promoted to Professor and was selected to lead the School of Engineering and Applied Science at Nile University as the School Dean, when he re-structured the school, established new academic bylaws and launched Quality System at the school and the institution leading to Pearson (UK) accreditation of Nile University in 2018. In 2009, Prof. Akl has received the National Encouragement Prize from the Academy for Scientific Research and Technology (ASRT).
Systematic university decision making based on footprint identifiers
A new systematic decision-making framework for universities is presented. The framework avoids the disadvantages of the balanced score cards technique. A solid mathematical technique is provided for mapping processes and quality items. Application to the Egyptian system is fully explained. The footprint concept developed within an international initiative is introduced. The mathematical
Active control of the dynamic density of acoustic metamaterials
All attempts to develop acoustic metamaterials with prescribed characteristics are based on utilizing the concepts of resonance frequencies of the metamaterial cell structure or on the spatial arrangement of two-or multi-phase domains to realize density or bulk modulus values on the micro scale that influence the wave propagation on the macro scale. In here, a radically different concept is
Dynamic behavior of polyurea composites subjected to high strain rate loading
A comprehensive theoretical and experimental investigation is presented of the behavior of polyurea composites subjected to high strain-rate impact loading. The composites under consideration consist of an assembly of steel sections and inserts manufactured from layers of polyurea or polyurea augmented with aluminum layers (AL). A finite element model (FEM) is developed to predict the dynamics of
Testing of the Aerodynamic Characteristics of an Inflatable Airfoil Section
Inflatable structures are characterized by being light and easy to manufacture and deploy. Hence, they find many applications in aerospace and aeronautical engineering. In this paper, an inflatable segment with a The National Advisory Committee for Aeronautics (NACA) 0021 airfoil cross-section is designed, fabricated, and tested. The geometrical accuracy of the manufactured inflatable segment is
Dynamic behavior and damping characteristics of carbon black polymer composites at high strain rates
The dynamic stress–strain behavior and the damping characteristics of carbon black (CB)/polymer composites at high strain rates are measured using the split Hopkinson pressure bar. These characteristics are determined for polyurethane impregnated with 20% CB nanoparticles and compared with those of pristine polyurethane at strain rates ranging between 2,400 and 7,000 s−1. The obtained results
Ab initio density functional theory investigation of the interaction between carbon nanotubes and water molecules during water desalination Process
Density functional theory calculations using B3LYP/3-21G level of theory have been implemented on 6 carbon nanotubes (CNTs) structures (3 zigzag and 3 armchair CNTs) to study the energetics of the reverse osmosis during water desalination process. Calculations of the band gap, interaction energy, highest occupied molecular orbital, lowest unoccupied molecular orbital, electronegativity, hardness
Energy harvesting of gas pipeline vibration
Pipelines conveying gas under pressure exhibit turbulence-induced vibrations. The current work is concerned with extracting useful power from pipelines operating well within their stability region. At such regions, the pipe vibrations exist in small magnitudes and are unlikely to cause structural failure, yet can be exploited to provide useful energy for low-power electronic devices. Accordingly
Configurations of active acoustic metamaterial with programmable bulk modulus
Acoustic MetaMaterials (AMM) have been considered as effective means for controlling the propagation of acoustical wave energy through these materials. However, most of the currently exerted efforts are focused on studying passive metamaterials with fixed material properties. In this paper, the emphasis is placed on the development of a new class of one-dimensional acoustic metamaterials with
