Corrosion is a major cause of early failure in palm oil mill infrastructure Aceh, Indonesia. Therefore, the aim this study to analyze corrosion rate steel used industry and determine remaining life steel. Round bars plates made were as exposure samples. This sample was cleaned impurities ground with sandpaper obtain 600 grating, then washed clean water rinsed strong liquid, presented climate at...

Merbau wood is a type of tropical hardwood class I-II having resistance to humid weather and so that the widely used in many building constructions, such as bearing houses bridges. In addition, this can be raw material for furniture because it has high durability against fungi. The tensile test specimen (ASTM D4761) fatigue E466) were made by turning smoothing surface with sandpaper. Furthermor...

The effects of corticomuscular connectivity during object manipulation tasks with different haptic sensations have not been quantitatively investigated. Connectivity analyses enable the study cortical and muscle responses movements, revealing communication pathways between brain muscles. This aims to examine three Electroencephalography (EEG) channels five muscles involving contact surfaces San...

Abstract The wood surface quality is most determined by the way in which it has been processed before and tools used for this purpose. Machining its effect primarily on structural shape of formed after tool–wood contact also roughness obtained a specific process. In cases, surfaces elements are materials or semi-finished products further processes, including gluing painting, sanded with sandpap...

Alkali activated materials (AAMs) were considered as economical and environmentally friendly that have attracted incrementally attention green coating materials. However, alkali inclined to be infiltrated ruined by harmful ions in water due their hydrophilicity. And the ordinary ways of construct superhydrophobic coatings costly, complex need fluorine material. The surfaces fragile owing super-...

Abstract Lubricants are often contaminated by water in different ways. Water-polluted lubricants extremely accelerate wear corrosion, leading to the deterioration of lubricity performance. Recently, multiphase media superwettability has been developed endow one surface with compatible functions, such as on-demand separation oily wastewater. However, realizing robustness dual superlyophobic solv...

Terrestrial gastropods display monotaxic direct crawling. During locomotion, smooth muscle contraction stimulates a series of pedal waves that move along the ventral surface foot. These interact with thin layer mucus produced by foot, propelling animal forward. Although mechanism which this process occurs has been well studied, less is known about how morphological or environmental factors affe...

We have previously described a technique to quantify surface fibrillatory changes in osteoarthritic articular cartilage. In that study, the angular distribution of the scattered acoustic field from an insonifying source directly related to the distribution of surface fibrillatory changes. In the current study, we demonstrate a more sensitive method to quantify surface roughness, the effect of g...

In this paper, we present a fast machine vision method for the automatic inspection of defects in textured surfaces. Traditional 2D Gabor filtering schemes have shown to be very effective for detecting local anomalies in textured surfaces of industrial materials. However, they are computationally expensive and sensitive to image rotation. In order to alleviate the limitations of 2D Gabor filter...

Neural classifier for multi-purpose image recognition systems is developed. One of the applications is an adaptive control system based on image recognition system for micromechanics where the limited receptive area (LIRA) neural classifier is proposed for texture recognition of mechanically treated metal surfaces. The performance of the proposed classifier was tested on image database with fou...
