Abstract The ability to accurately realize complex textures is of great relevance for tailoring surface-driven functionalities as wettability, adhesion and light diffraction. fabrication superficial micro-textures, in a simple cost-effective way, high desiderable this framework. A versatile technique surface micropatterning based on reconfiguration photosensitive azobenzene-containing polymers,...

This study investigates the effect of laser surface texturing on the friction behavior of grey cast iron reciprocating under boundary, mixed lubrication conditions and cyclic loading. Four geometrical parameters of micro-textures (feature depth, feature diameter, area fraction, and sliding direction) were studied using a design of experiments (DoE) approach. The results showed that depending on...

Ultraprecision textured surfaces with functional requirements are extensively used in engineering, optics, biomedical and microelectronic products. This work investigates backside patterning of micro-scale textures with nanometer surface finish on flat surfaces. In this technique a pre-fabricated macro-scale backside pattern was machined as a first step, and thereafter the front side of the wor...

A system is proposed which analyzes various textures statistically or structurally, depending on the nature of the textures. The system first describes a texture globally by both gray level first order statistics and edge statistics to roughly classify it. Next, the system extracts homogeneous gray level regions to try to describe the texture structurally. However, if too many regions are extra...

In this paper, we desribe mdti-displacement cooccurrence matrices for re~enting W ice textures of SAR imagery. Our design of co-occcurrence matrices captures local relationships among neighboring pixels and global links among distant pixels, an advantage over other existing versions of co-occurrence matrices. As a result, it can adequately represent micro textures, such as grainy details, and m...

Texture boundaries or edges are useful information for segmenting heterogeneous textures into several classes. Texture edge detection is different from the conventional edge detection that is based on the pixel-wise changes of gray level intensities, because textures are formed by patterned placement of texture elements over some regions. We propose a prediction-based texture edge detection met...

This paper proposes a new approach for paint appearance simulation. Coatings color and appearance change significantly according to lighting and observation conditions. The aim of this study is to propose both real time and accurate solutions for painted surface simulation. To solve real time constraints, we have chosen to simulate the paint appearance thanks to textures. Each texture represent...

nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. in this paper, ultrasonic assisted turning (uat) isperformed to create the micro textures on the flat faces. micro surface texturing ismade on the al7075-t6 by the uat in the face turning process. then, the influences of cutting speed feed, vibration direction and vibration ampl...
