Microbial-induced calcium carbonate precipitation (MICP) is often used to improve the engineering properties of different building materials in recent years, which has great development prospects. This process takes advantage metabolic activity microorganisms and eventually leads through changes microbial environment. The self-healing effect (SH effect) concrete can be explained as ability repa...

Production optimization of gas-lifted oil fields under facility, routing, and pressure constraints has attracted the attention of researchers and practitioners for its scientific challenges and economic impact. The available methods fall into one of two categories: nonlinear or piecewise-linear approaches. The nonlinear methods optimize simulation models directly or use surrogates obtained by c...

This paper proposes a Mixed Integer Conic Programming (MICP) model for community microgrids considering the network operational constraints and building thermal dynamics. The proposed multi-objective optimization model optimizes not only the operating cost, including fuel cost, electricity purchasing/selling, storage degradation, voluntary load shedding and the cost associated with customer dis...

background: monte carlo determination of tg-43 brachytherapy dosimetry parameters and dose distribution calculation for 131cs source model cs-1 are presented in this study. materials and methods: the dose distribution was calculated around the 131cs model cs-1 located in the center of 30 cm ×30 cm ×30 cm water, and soft tissue phantoms cube using mcnp code by monte carlo method. the percentage ...

background: reference charts are widely used in healthcare as a screening tool. this study aimed to produce reference growth charts for school children from west malaysia in comparison with the united states centers for disease control and prevention (cdc) chart. methods: a total of 14,360 school children ranging from 7 to 17 years old from six states in west malaysia were collected. a two-stag...

In this paper, at first we derive a family of maximum Tsallis entropy distributions under optional side conditions on the mean income and the Gini index. Furthermore, corresponding with these distributions a family of Lorenz curves compatible with the optional side conditions is generated. Meanwhile, we show that our results reduce to Shannon entropy as $beta$ tends to one. Finally, by using ac...
