Offshore pipelines are usually constructed by the use of girth welds, while welds may naturally contain flaws. Currently, fracture assessment procedures such as BS 7910 are based on the stress-based methods and their responses for situations with large plastic strain is suspicious. DNV-OS-F101 with limited modifications proposes a strain-based procedure for such plastic loads. In this paper 3D ...

In this work, we present a deep neural network architecture that can efficiently surrogate classical elasto-plastic constitutive relations. The is enriched with crucial physics aspects of elasto-plasticity, including additive decomposition strains into elastic and plastic parts, nonlinear incremental elasticity. This leads to Physics-Informed Neural Network (PINN) model named here as Elasto-Pla...

When people learn that I study lethal injection, they are usually curious to know more (or at least they are polite enough to ask questions). Interestingly, the question that arises most often— from lawyers, law students, and laypeople—is why states behave as they do. In the wake of botched executions and ample evidence of lethal injection‘s dangers, why do states fail to address their executio...

Word form segmentation abilities emerge during the first year of life, and it has been proposed that infants initially rely on two types of cues to extract words from fluent speech: Transitional Probabilities (TPs) and rhythmic units. The main goal of the present study was to use the behavioral method of the Headturn Preference Procedure (HPP) to investigate again rhythmic segmentation of sylla...

Here we show the existence of a smooth complex projective curve Z P 3 of degree d and genus g such that TP 3 jZ is stable for all integers d; g such that (roughly) d 2 =9 < g < (d?1) 2 =8. Following a construction of Gruson and Peskine we will nd such a curve Z on an integral rational quartic surface with a double line. We will use in an essential way also the main properties of stable vector b...

Based on Johnson's (1994) across-the-board (ATB) movement analysis of Gapping, Agbayani and Zoerner (2004) argue that Gapping involves the application of sideward movement of the main verb out of coordinate structures. In this paper, I show that the verb movement analyses of Gapping are problematic. Ultimately, I maintain that Gapping is a discourse-oriented variant of TP ellipsis. More precise...

Disordered soft materials, such as fibrous networks in biological contexts, exhibit a nonlinear elastic response. We study such nonlinear behavior with a minimal model for networks on lattice geometries with simple Hookian elements with disordered spring constant. By developing a mean-field approach to calculate the differential elastic bulk modulus for the macroscopic network response of such ...

Experimental measurements of the Poisson's ratio in tendon and ligament tissue greatly exceed the isotropic limit of 0.5. This is indicative of volume loss during tensile loading. The microstructural origin of the large Poisson's ratios is unknown. It was hypothesized that a helical organization of fibrils within a fiber would result in a large Poisson's ratio in ligaments and tendons, and that...

This paper explores the optimal treatment of an infectious disease in a Susceptible-Infected-Susceptible model, where there are two strains of the disease and one strain is more infectious than the other. The strains are perfectly distinguishable, instantly diagnosed and equally costly in terms of social welfare. Treatment is equally costly and effective for both strains. Eradication is not pos...

There has been a considerable amount of work carried out on two-dimensional laser forming. In order to advance the process further for industrial applications, however, it is necessary to consider more general cases and especially their process planning aspect. This paper presents an optimal approach to laser scanning paths and heating condition determination for laser forming of doubly curved ...
