We present a coarse-graining model that enables the description of pressure-induced, endothermic reactions in a model material. An additional implicit variable (the particle size) is used to describe particles undergoing volume-reducing endothermic reactions via a bistable intra-molecular potential, whereas the dynamics of the centerof-mass motion evolves according to interparticle forces. The ...

Rubble mound near-bed structures are among the more common hydraulic structures. Examples include bottom protections to prevent scour near bridge piers, offshore structures, weirs and sluices and at the toe of bank protections or breakwaters, but also pipe covers on offshore pipelines. The cornerstone of the theory behind the design of these structures was laid by Izbash (1930) and, most notabl...

Metastable austenitic stainless steel was investigated during fatigue tests under strain control with either constant total or plastic amplitude. Two different material conditions coarse-grained and ultrafine-grained microstructure were in focus. The influence of the test on both martensitic phase transformation as well lives is discussed. In addition, an approach for calculating Coffin–Manson–...

This supplementary material is organized as follows. Sec. 2.1 and Sec. 2.2 present proofs for the Eq. 4 in the paper in the case of max and average pooling operator, respectively. Sec. 2.3 substantiates variance statements associated with Eq. 6 and Eq. 7 in the Section 3.3. Sec. 3 shows numerical details for Fig. 4 and Fig. 5 in the paper. Last, Sec. 4 shows examples of object instances in JHUI...

This paper presents a randomize, coarse-grained, parallel algorithm which computes the 3-dimensional convex hull of a set of points with high probability in O(n log n p) time, where n is the number of points, and p is the number of processors. Furthermore, O(1) communication steps are used, with O(n=p) data sent at each step, by each processor. The material presented in this paper summarizes th...

SEMmicrograph of a multimodal grained tungsten material after being irradiated with 200 eV He ions at 950 C and a fluence of 1 10 m 2 showing the detachment and the nanostructuring of the small grains as well as pore formation on top of the nanostructures. The sample was etched before irradiation for better imaging of the grain boundaries. a r t i c l e i n f o

This tutorial review covers recent progress in the field of computer simulation of liquid crystals. The development of the main "molecular-based" models for liquid crystals is described. These include lattice models, coarse-grained single site models based on hard and soft interaction potentials, atomistic models and multi-site coarse-grained models. A brief historical review is followed by an ...

Synthetic fluorspar can be produced from waste calcium fluoride slurry settled on dumpsites located near Cracow centre. Synthetic fluorspar exchanges natural raw material used in the metallurgical industry. To obtain grained synthetic fluorspar, calcium fluoride slurry should be calcinated in rotary kilns at temperatures of 900-1100K. Grain size and compression strength strongly depends on calc...

Use of the scanning electron microscope (SEM) with X-ray microanalysis allows study of clinker and cements; permitting measuring bulk phase abundance and surface areas of the phases, as well as bulk chemistry of constituent phases can be carried out. Direct imaging of hydraulic cements by SEM yields a more complete picture of both bulk and surface phase compositions. Mass percentages obtained b...
