In this study, the effects of yarn parameters, on the bursting strength of the plain knitted fabrics were examined with the help of artificial neural networks. In order to obtain yarns having different properties such as tenacity, elongation, unevenness, the yarns were produced from six different types of cotton. In addition to cotton type, yarns were produced in four different counts having th...

The impact of card cylinder speed, card production rate and draw frame doubling on cotton yarn quality parameters was investigated by using the BoxBehnken experimental design. It was found that yarn tenacity, elongation and hairiness increase by increasing the number of draw frame doubling up to a certain level and then decrease by further increase in doubling. Yarn unevenness increased by incr...

The paper presents a method of visualisation of surface microroughness acquired by hydroabrasive division (AWJ – abrasive water jet), by means of polygon representation. The method stems from theoretical and practical possibilities of so-called global illumination mapping of unevenness using suitable image maps. Based on data interpretation stemming from measurement of the surface roughness, an...

Surveying the condition of pavement is one most important processes in managing road network. The information collected during these surveys allows for calculation Pavement Condition Index, which a derivative cumulative qualitative indicator that evaluates various characteristics and defects. Deterioration modelling measured indicators calculated indices critical element its accurate prediction...
