There is no agreement on how to predict punching shear for footings among different design codes, which is inconsistent with experimentally observed capacity. Such inconsistency is due to the following issues: (1) the different definitions used by de

Fiber-reinforced polymer (FRP)-reinforced concrete (RC) elements fail under one-way shear in a devastating and complicated manner with no adequate warning. In recent decades, there has been pioneering research in this area; however, there is no agree

The shear behavior of concrete beams is highly affected by the implementation of better performance concrete. Hybrid fibers addition to concrete mixture has proven to improve the performance compared to just using single type of fiber. Thus, in this

Combining different types of fibers inside a concrete mixture was revealed to improve the strength properties of cementitious matrices by monitoring crack initiation and propagation. The contribution of hybrid fibers needs to be thoroughly investigat

Sugarcane Bagasse Ash (SCBA) is one of the most common types of agricultural waste. By its availability and pozzolanic properties, sugarcane bagasse ash can be utilized as a partial replacement for cement in the production of sustainable concrete. Th

The combinatorial liquidity management problem is formally defined. The nature and complexity of the resulting mathematical program are discussed. Casting the ensuing mathematical program into the physical analog of a network flow model offers a natu

Context: Four-dimensional speckle-tracking echocardiography (4D-STE) is ideal to accurately assess myocardial deformation. The novel 4D global area strain (GAS) uses global longitudinal and global circumferential strains (GCSs) to detect subtle chang

To ensure accurate market compliance, yield curves used for marking-to-market are typically constructed of as many liquid fixed income instruments as possible. This can result in curves of very high cardinality. The high cardinality associated with s

In this short technical note we present an efficient algorithm for the maximization of the Liquidity Cover Ratio (LCR) when lower level asset caps are activated. This algorithm acts by selecting the most efficient assets to remove from the pool of su
