Abstract Capacity prediction of surface mount production lines is important for improving productivity, dynamic scheduling, and optimizing structure. An integrated mutual information-cuckoo search-extreme learning machine (MI-CS-ELM) model proposed the impact nonlinear high-dimensional features surface-mounted on capacity. Firstly, affecting capacity are ranked based information method, predict...

the nanocomposites of poly (acryl amide-co-acrylic acid) with different contents of naazeolite were prepared using ammonium persulfate as an initiator and n, n′-methylenebisacrylamide as the crosslinker. the morphology was characterized by sem and the structure ofnanocomposite materials was studied with xrd and ft-ir that showed the interaction betweenporous materials and poly (aam-co-aac). the...

In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...

The damping in a carbon fiber reinforced plastic (CFRP) laminate is greater than that which occurs in most metallic materials. In the supercritical regime, the damping can trigger unstable whirl oscillations, which can have catastrophic effects. The vibrations occurring in a supercritical composite drive shaft are investigated here in order to predict instabilities of this kind. A simply suppor...

Immersive, stereoscopic viewing enables scientists to better analyze the spatial structures of visualized physical phenomena. However, their findings cannot be properly presented in traditional media, which lack these core attributes. Creating a presentation tool that captures this environment poses unique challenges, namely related to poor viewing accessibility. Immersive scientific renderings...

In high reliable industries, where critical information is often given in real time, Head-Mounted Displays (HMDs) may support workers. Especially if mobility is needed, like in maintenance or some fields of medicine, HMDs can display this critical information directly within the field of view. However, in a study presented on last year ́s conference of HFES-Europe we showed that participants rea...

The chemical analysis of microparticles is challenging due to the need mount particles on a substrate for analysis; double-sided adhesive tape often used (sometimes conductive), however that usually coated with poly (dimethyl siloxane) (PDMS) as release agent. PDMS common surface contamination can mask chemistries and hinder material performance where it dependent this contaminated interface. I...
