Modeling buildings response to blast and subsequent progressive collapse interested more and more researchers during the past two decades. Due to the threat from extreme loading, efforts have been made to develop methods of structural analysis and design. In this paper, progressive collapse capacity of steel moment frames was first investigated using alternate load path method, then a nonlinear...

A debutanizer column is an integral part of any petroleum refinery. Online composition monitoring of debutanizer column outlet streams is highly desirable in order to maximize the production of liquefied petroleum gas. In this article, data-driven models for debutanizer column are developed for real-time composition monitoring. The dataset used has seven process variables as inputs and the outp...

We report on the design and performance of in-house built column cartridges that can be directly screwed into ports a commercial rotor-stator valve to minimize extra-column band broadening pressure-drop losses when pursuing ultra-fast separations such as those needed in 2D 3D-LC separations. Two basic designs were evaluated compared with results obtained screw-in cartridge. The system produces ...
