Nowadays, the significance of keeping equipment function properly each time is obvious. If equipment fails during its use, it may have disastrous consequences. Estimating remaining useful life (RUL) of equipment is a key to prevent such calamities, improve its reliability, provide security and reduce unnecessary maintenance and operational cost. The evolution and tracking of damage is the found...

Abstract Incremental sheet forming (ISF) is an emerging technology for manufacturing metal components with fewer tools and equipment compared to conventional forming. In this process, generally performed without dies punches a simple hemispherical shaped tool can be used shaping the final component. Forming limit in incremental defined by maximum formable wall angle. Finite element analysis fra...

Firefly algorithm (FA) is an optimization technique inspired by an intelligent behavior of firefly swarms. This paper presents an application of FA to Gaussian process (GP)-based prediction of electric power damage caused by typhoons. The GP prior model for prediction is trained by a separable least-squares (LS) approach combining the linear LS method with FA. The proposed prediction system yie...
