An Investigation on the Effects of Aggregates Properties on the Performance of Unbound Aggregate Base Layer

Unbound aggregates are the most common type of materials used for construction of the base layer of flexible pavements in Iran and worldwide. Due to the lack of binder, the performance of the compacted unbound aggregates is highly dependent on the properties of the gravel (particles remaining on sieve 4.75mm, sand (particles passing sieve 4.75mm and remaining on sieve 0....

Theoretical Investigation of Cold Alkali Atom Collisions

Influence Of Alkali And Temperature On Fixation And Color Coordinates In Dyeing With Different Reactive Dyes

Influence of alkali and temperature were studied on dyeing of cotton fabric with bi-functional Fluoro Chloro Pyrimidene (FCP), bi-functional Monochlorotriazine-Vinyl Sulphone (MCT-VS) and mono functional Monochlorotriazine (MCT) reactive dyes. For this analysis single joursey knitted fabrics were taken. The selected dyestuffs were Drimarene Yellow K-2R (FCP), Drimarene Red CI-5B (MCT-VS) and Dr...

Segmentation of Petrographical Images of Marbles

Microscope images of marble thin sections can be used to determine their geographical origin by means of the shapes, sizes, and spatial distribution of their grains. In this paper, we present a method that is the first step towards an automatic origin determination, namely, the segmentation of grains in digital images of thin marble sections. Each grain has a preferred direction, different from...
