Optimizing the shielding properties of strength-enhanced concrete containing marble

Papers in Physics, 2020
The purpose of this study is to develop a low cost, locally produced concrete mixture with optimum marble content. The resulting mixture would have enhanced strength properties compared to the non-marble reference concrete, and improved radiation ...

Oedometric study of dredged marine soils admixed with sand for settlement reduction [PDF]

, 2017
Dredged marine soils (DMS) can be reused as fill materials for land reclamation project other than dump back to the open sea. However, in Malaysia, dredged marine soils were considered as a geowaste because of it has poor engineering properties.

Gradient Path Functionally Graded Materials Fabricated by DMD using SS316L and IN625 Powders [PDF]

Archives of Metallurgy and Materials
Additive Manufacturing (AM) is a layer-by-layer material addition process. Direct Metal Deposition (DMD) is one of the metal powders feeding AM methods. It can produce Functionally Graded Material (FGM) used in extreme service conditions.

Microbial co-occurrence network topological properties link with reactor parameters and reveal importance of low-abundance genera

npj Biofilms and Microbiomes, 2022
Operational factors and microbial interactions affect the ecology in anaerobic digestion systems. From 12 lab-scale reactors operated under distinct engineering conditions, bacterial communities were found driven by temperature, while archaeal ...

Confidence Regions for Steady-State Probabilities and Additive Functionals Based on a Single Sample Path of an Ergodic Markov Chain

Mathematics
Discrete, finite-state Markov chains are applied in many different fields. When a system is modeled as a discrete, finite-state Markov chain, the asymptotic properties of the system, such as the steady-state distribution, are often estimated based on a ...

On sample path properties of semistable processes

Journal of Multivariate Analysis, 1987
The authors show that the well-known correspondence principle between Gaussian and stable processes and measures on \(L_ p\) spaces extends to Banach valued r-semistable index \(\alpha\) processes and measures on \(L_ p\), \(1\leq ...
