3D concrete printing of permanent formwork for concrete column construction

, 2021
This study investigated 3D concrete printing of permanent formwork for concrete column construction. The effect of different hydroxypropyl methyl cellulose (HPMC) contents (0, 0.0003 and 0.0006 by mass of binder) and the water-to-binder (W/B) ratios (0 ...

Automata column

ACM SIGLOG News, 2022
For the Automata Theory Column, we have an article by B. Srivathsan on the reachability problem in timed automata. Ever since timed automata were introduced by Alur and Dill, they have been widely used in the verification of real-time systems. Their appeal comes from a simple definition that couples expressiveness with computational tractability.

Complexity Column

ACM SIGLOG News, 2022
Descriptive complexity theory initiated by celebrated Fagin's theorem aims to characterize complexity classes by the kind of logic necessary to express problems in the class. For many complexity classes such a characterization has been found; this includes the class NP that, according to Fagin's theorem, can be characterized by the monadic second order

Machine-Learning-Based Column Selection for Column Generation

Transportation Science, 2020
Column generation (CG) is widely used for solving large-scale optimization problems. This article presents a new approach based on a machine learning (ML) technique to accelerate CG.

Column Overload in PLOT Columns

LCGC North America, 2022
Injecting too much sample onto a chromatographic system will eventually overload the column. Analytical chemists are concerned about column overloading because it reduces column efficiency, and, as a result, the resolution is sacrificed. Surprisingly, there is little data in the literature about the overloading of the porous layer open tubular (PLOT ...
