In [1] we introduced a new state-space relaxation, called ng-path relaxation, to compute lower bounds to routing problems, such as the Capacitated Vehicle Routing Problem (CVRP) and the VRP with Time Windows (VRPTW). This relaxation consists of partitioning the set of all possible paths ending at a generic vertex according to a mapping function that associates with each path a subset of the vis...

the photocatalytic decolorization of aqueous solutions brown ng, a commercial textile dye, was studied using titana degussa p-25 as a catalyst for the first time. the experiments were carried out in a batch reactor with the use of artificial light sources (uv-c). the effects of various process variables on decolorization performance of the process have been investigated. the photodegradation of...

An Instrumented task board has been developed at NASA Marshall Space Flight Center (MSFC). An overview of the task board design, and current development status is presented. The task board was originally developed to evaluate operator performance using the Protoflight Manipulator Arm (PFMA) at MSFC. The task board evaluates tasks for Orbital Replacement Unit (ORU), fluid connect and transfers, ...
