1. Effect of Shear Reinforcement as Horizontal Restraint on the Bearing      Capacity of Bridge Deck Slab using Strut-and-Tie Model

Software used: Abaqus

Effect of Shear Reinforcement as Horizontal Restraint on the Bearing Capacity of Bridge Deck Slab using Strut-and-Tie Model was founded by Najiyu Abubakar, Redzuan Abdullah, Ahmad Beng Hong Kueh, Mohamad Salleh Yassin.

The purpose of this paper is to carry out an analysis and provide a design method for the disturbed/discontinuous regions of concrete bridge deck slab-on-girder, with simplicity and accuracy using strut-and-tie model. Strut-and-tie model in designs of reinforced concrete structures involve the use of some basic tools that include struts, ties and nodes.

2. Density functional theory study of electronic properties of Bi2Se3 and      Bi2Te3

Software used: Quantum Espresso

Density functional theory study of electronic properties of Bi2Se3 and Bi2Te3 was founded by Abdullahi Lawal, Amiruddin Shaari.

Topological insulators are layered materials via van der Waals interactions with hexagonal unit cell similar to that of graphene. The exciting features of Bi2Se3 and Bi2Te3 topological insulators their zero band gap surface states exhibiting linear dispersion at the Fermi energy. We present here first principles study pertaining to electronics properties of Bi2Se3 and Bi2Te3 compound with and without spin-orbit interaction using density functional theory (DFT).

3. Sparse Coding Based Classification of Electrocardiography Signals      Using Data-Driven Complete Dictionary Learning

Software used: Matlab

Sparse Coding Based Classification of Electrocardiography Signals Using Data-Driven Complete Dictionary Learning was founded by Fuad Noman, Sh-Hussain Salleh, Chee-Ming Ting, Hadri Hussain, Syed Rasul.

In this paper, a data-driven dictionary approach is proposed for the automatic detection and classification of cardiovascular abnormalities. Electrocardiography (ECG) signal is represented by the trained complete dictionaries that contain prototypes or atoms to avoid the limitations of pre-defined dictionaries.

4. Aerodynamic Sound From A Square Cylinder With A Downstream      Wedge

openfoam-sukri

Software used: OpenFOAM

Aerodynamic sound from a square cylinder with a downstream wedge was founded by Siti Ruhliah Lizarose Samion, Mohamed Sukri Mat Ali, Aminudin Abu, Con J.Doolan, Ric Zong-Yang Porteous.

The effect of placing a wedge in the wake of a square cylinder (side length D) at a Reynolds number of 22,000 is numerically investigated. In particular, the effect of the wedge on aerodynamic noise is observed along with its effect on the flow field. Wedge base height (h) and its gap distance (G) downstream of the cylinder are systematically varied.

5. Subsea Pipeline Safety Margin Theory

Safety Margin

Safety Margin Subsea Pipeline Theory was founded by A.K.Junaidi, J.Koto, Ocean & Aerospace Research Institute, Indonesia collaborate with Mechanical Engineering, Universiti Teknologi Malaysia, Malaysia.

Safety margin of pipeline wall thickness is a minimum wall thickness selection based on either internal or external pressure. In subsea application, the determination of wall thickness safety margin depends on the biggest one of the minimum wall thickness between internal and external calculation. So it can be called as dominant safety margin.
The theory has been transferred into commercial software which is called Subsea Pro Software.
