Experimental investigation of the performance of palm kernel shell and periwinkle shell as partial replacement for coarse aggregate in asphaltic concrete

Journal of Building Materials and Structures, 2016
Performance of non-conventional materials namely palm kernel shell (PKS) and periwinkle shell (PWS) were investigated. Sieve analysis, aggregate impact value (AIV), aggregate crushing value (ACV), bitumen penetration, Marshall Stability, flash and fire ...

Trophic interactions and ecological stability across coral reefs in the Marshall Islands [PDF]

Marine Ecology Progress Series, 2013
Coral reef assemblages, trophic interactions, and food web stability were examined across a remote and densely populated atoll, in the Republic of the Marshall Islands (RMI). The biomass of sharks, large-bodied piscivores, and secondary invertebrate consumers was expect- edly larger in the absence of major human populations. Less intuitively, we report

Comparison of Marshall Stability values of the different bitumen mixes with crumb rubber

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Modified bitumen with crumb rubber can enhance the bitumen’s physical properties and the mixes’ Marshall Stability values. Aside from the fact that it reduces the amount of tyre waste, the use of crumb rubber can also improve the properties of bitumen, which can help to extend the life of flexible pavements.

Marshall Stability Estimating Using Artificial Neural Network with Polyparaphenylene Terephtalamide Fibre Rate

2016 International Symposium on INnovations in Intelligent SysTems and Applications (INISTA), 2016
Due to the complex behaviour of asphalt pavement materials under various loading conditions, pavement structure, and environmental conditions, accurately predicting stability of asphalt pavement is difficult. To predict, it is required to find the mathematical relation between the input and output data by an accurate and simple method. In recent years,

The stability of a characterization of the bivariate Marshall-Olkin distribution

Journal of Mathematical Analysis and Applications, 1991
The authors introduce a class of weakly bivariate NBU (briefly WBNBU) distributions which survivor functions possess the following two properties: \begin{align*} G(x+t,y+t) &\leq G(x,y)G(t,t)\quad && \text{ for all } x,y,t\geq 0;\tag{i}\\ G_ i(x+t) &\leq G_ i(x)G_ i(t)\quad && \text{ for all } x,t\geq 0,\tag{ii} \end{align*} where \(G_ i\) is the ...
