This study examines evolution characteristics of inelastic strains and materials damage in Sn-4Ag-0.5Cu (SAC405) solder joints of a BGA package under cyclic mechanical stressing. For this purpose, a finite element model of the assembly under four-point bend test set-up is employed. Strain rate-dependent response of the solder is represented by Anan

The multidisciplinary field of tissue-engineering was born as a means to restore or replace diseased tissue with new living tissue that is designed or constructed to meet the needs of each individual patient. Scientific advances in biomaterials, stem cells, growth factors, and biomimetic environments have created opportunities to reconstruct tissue

Identifying the intraocular lens (IOL) material is an important step before further mechanical and optical testing can be done. The characterization of the materials is particularly important during the finite element analysis where the simulation of the lens can be performed in accordance to the well-established standards. The aim of this work is

In a construction industry, a Condition of Contract (CoC) is primarily used to ensure a project can be delivered successfully with minimum disputes. The contractual disputes rooted from many factors, including from the improper management of conflict between parties in the project, misinterpretation of the CoC, lack of documentation, and discrepanc

We introduce the notion of a PT -symmetric dimer with a χ(2) nonlinearity. Similarly to the Kerr case, we argue that such a nonlinearity should be accessible in a pair of optical waveguides with quadratic nonlinearity and gain and loss, respectively. An interesting feature of the problem is that because of the two harmonics, there exist in general

Recently, many researches all over the world are focusing on ways of utilizing either industrial or agricultural wastes as a source of raw materials for the construction industry. The aim of this study is to determine the optimum proportion of durian saw dust as partial replacement for fine aggregate. These wastes utilization would not only be econ

The COVID-19 pandemic in 2020 has caused a major transformation in the education system around the world. Due to the closure of schools and other learning institutions, the teaching and learning that were once face to face are now conducted online. Sudden change of education landscape has put educators and students in harrowing time. This paper rev

This study was conducted to examine the association between physical activity (PA) and body weight status among adolescents in rural and urban areas. This cross-sectional study involved 257 adolescents aged 13–19 years, randomly selected from secondary schools around Kelantan, Malaysia. Body weight and height were measured and body mass index (BM
