We present the design of a concentric tube (CT) reactor for roll-to-roll chemical vapor deposition (CVD) on flexible substrates, and its application to continuous production of graphene on copper foil. In the CTCVD reactor, the thin foil substrate is helically wrapped around the inner tube, and translates through the gap between the concentric tubes. We use a bench-scale prototype machine to sy...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

We studied caloric nystagmus before and after plugging all six semicircular canals to determine whether velocity storage contributed to the spatial orientation of caloric nystagmus. Monkeys were stimulated unilaterally with cold ( approximately 20 degrees C) water while upright, supine, prone, right-side down, and left-side down. The decline in the slow phase velocity vector was determined over...

Machine-to-Machine (M2M) Communication is one of the most attractive technology used in both industrial and education sectors and that is predicted to grow within the next few years. It provides a way of communication between connected devices. Very important obstacles which will cut down M2M Communication growth and even hold back the large roll-out of sure applications are security and privac...

Linear Low Density Polyethylene-Natural Rubber (LLDPE-NR) composites in the ratio of 70:20 were made with different loadings of nanosilica and micro-scale Palm Oil Fuel Ash (POFA). Linear Low Density Polyethylene grafted with maleic anhydride (LLDPE-g-MAH) of 10 wt% was added as a compatibiliser. The composites were produced by using two-roll mill machine. The tensile properties of the composit...

The use of machine learning algorithms to improve productivity and quality maximize efficiency in the steel industry has recently become a major trend. In this paper, we propose an algorithm that automates setup cold-rolling process maximizes by predicting roll forces motor loads with multi-layer perceptron networks addition balancing increase production speed. proposed method first constructs ...

Range imagery produces the kind of geometric information about the environment that an autonomous machine needs for operation. Not only does the range data provide explicit information about the obstacles that might hinder movements, but it also provides a means of recognizing objects that should be manipulated. TULKO, the \Machine of the Future" project, has chosen laser range imagery as it ma...

Microstructure evolution, mechanical properties, formability, and texture development were determined for AA6111 samples processed by asymmetric rolling (ASR) with different roll friction, velocity, or diameters, conventional rolling (CR), and equal-channel-angular pressing (ECAP). Highly elongated or sheared grain structures were developed during ASR/CR and ECAP, respectively. ASR led to impro...
