one of the challenges of academic writing is the creation of a structurally and communicatively well-organized and coherent text. metadiscourse enables authors of journal articles to achieve this goal by raising the writers‘ awareness about discourse features which can contribute to a better academic content production. also, l1 background has always been a hot topic in applied linguistics and ...

While much attention has been given to understanding biases in gloss perception (e.g., changes perceived reflectance as a function of lighting, shape, viewpoint, and other factors), here we investigated sensitivity surface reflectance. We tested how visual differences specular varies the magnitude Stimuli consisted renderings glossy objects under natural illumination. Using maximum likelihood d...

A high spatial resolution imaging colorimeter and glossmeter is presented. The combination of a high quality imaging colorimeter with an off axis imaging optics and a highly stabilized RGB LED source allows color and gloss measurements of small parts with high accuracy. The characteristics of the system with some experimental results on black coated and printed papers are presented. Introductio...

Sufficient cause interactions concern cases in which there is a particular causal mechanism for some outcome that requires the presence of 2 or more specific causes to operate. Empirical conditions have been derived to test for sufficient cause interactions. However, when regression outcome models are used to control for confounding variables in tests for sufficient cause interactions, the outc...

Predicting the final appearance of a print is crucial in graphic industry. The aim this work to build mathematical model predict visual gloss 2D printed samples. We conducted psychophysical experiment where observers judged samples with different colours and values. For experiment, new reference scale was built. Using results from prediction for assessment has been developed. By using Principal...

In this study, we investigated the color, gloss and surface roughness of bamboo (Phyllostachys bambusoides) and Scots pine (Pinus sylvestris) samples impregnated with boron and copper based preservatives during accelerated weathering from 168 h to 672 h. Tanalith-E, ACQ, wolmanit-CB were used as copper-based chemicals, while a mixture of boric acid and borax (7:3; w/w) was used as the boron com...

Computer simulated stimuli can provide a flexible method for creating artificial scenes in the study of visual perception of material surface properties. Previous work based on this approach reported that the properties of surface roughness and glossiness are mutually interdependent and therefore, perception of one affects the perception of the other. In this case roughness was limited to a sur...
