43 A diverging diamond interchange (DDI), also called a double crossover diamond interchange 44 (DCD), is a relatively new interchange type in the U.S. Due to its many advantages over the 45 conventional diamond interchanges such as higher capacity and lower delay, there has been a 46 growing interest in its analysis methodologies and operational strategies. DDIs have shown 47 particularly high...

Highway Interchange projects present particularly complex and changing geometric configurations. Such configurations are hard to visualize and understand, and associated management, construction decisions, and traffic control strategies are difficult to optimize and communicate. This paper presents a computerbased system, which utilizes 3D and 4D CAD technology in order to: facilitate the commu...

SUMMARY ROBIN is a web server for analyzing genome rearrangement of block-interchanges between two chromosomal genomes. It takes two or more linear/circular chromosomes as its input, and computes the number of minimum block-interchange rearrangements between any two input chromosomes for transforming one chromosome into another and also determines an optimal scenario taking this number of rearr...

The kinetics and mechanisms of the substitution reactions of trans-[Co(en)2CNCl]+ with unidentate anions,  , CN¯, I¯,  , Br¯ and SCN¯ in 60% v/v DMF-H2O binary solvent at 40.0±0.2 °C were studied spectrophotometrically. An Id mechanism was assigned for the replacement of chlorine by , CN¯ and I¯, an Ia one for...
