Due to rapid development in information and communication technologies (ICT), daily life has been digitized with increasing momentum, the COVID-19 pandemic accelerated this situation more than ever. Depending on these developments excessive use of ICT, many new concepts have emerged, including screen fatigue. To respect, study aims develop a scale that determines fatigue among adolescents cause...

Abstract As the key components of sealing applications, rubber seals are subject to complicated environmental conditions during service lifetime. In this study, aging three typical materials, ethylene–propylene–diene monomer rubber, liquid silicone and fluorine was tested under different high- low-temperature cycle environments. The experimental results confirm that reciprocating temperature ca...

The reason of this study is low cycle failure of cast iron cylinder head during the E5 standard durability test. The goal of the present investigation is durability test simulation and low cycle fatigue life evaluation of cast iron cylinder head. With uncouple structural analysis, preloads, thermal and mechanical load and boundary conditions are prescribed to finite element model of the cylinde...

To give a proper and accurate estimation of the fatigue life of ball grid array (BGA) solder joints, a mechanical fatigue test method under mixed-mode loading is proposed. Experiments were conducted with 63Sn/37Pb and Sn/3.5Ag/0.75Cu solder joints in room temperature. The mechanical low cycle fatigue tests were performed under several loading angles. The loading angle is controlled by several g...

FAST is an algorithm proposed originally by Rosten and Drummond [1] for identifying interest points in an image. An interest point in an image is a pixel which has a well-defined position and can be robustly detected. Interest points have high local information content and they should be ideally repeatable between different images [2]. Interest point detection has applications in image matching...
