In this study, A2017-T4 aluminum alloy was plated with electroless Ni–P different phosphorus content and rotary bending fatigue test conducted to investigate the effect of hydrogen by plating on properties. The strength low-phosphorus type specimen higher than that untreated specimen, while high-phosphorus much lower. It is clear differs greatly depending in film. decrease high attributed induc...

In this paper, we propose to measure the intelligence of an agent by measuring how fast its knowledge level increases after learning related tasks. In this paper, we propose a new Lifelong Machine Learning Test. An agent can pass the test if it can learn unrestricted number of tasks over time and its knowledge level can increase when new tasks are learned. In the proposed test, both an agent’s ...

Fatigue is the major threat in service of steel structure subjected to fluctuating loads. With the additional effect of corrosion and presence of weld joints the fatigue failure may become more critical in structural steel. One of the apt examples of such structural is the sailing ship. This is experiencing a constant stress due to floating and a pulsating bending load due to the waves. This pa...

It is clear that the surface electromyographic-based (sEMG) human-machine interface (HMI) shows a reduction in stability when the muscle fatigue occurs. This paper presents an improved incremental training algorithm that is based on online support vector machine (SVM). The continuous wavelet transform is used to study the changes of sEMG when muscle fatigue occurs, and then the improved online ...

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...
