An experimental study on compressive strength of mortar mixes containing different amounts of rice husk ash (5, 10, 20%) has been investigated. The impact of different elevated temperatures (150, 300, 450, 750oC) on mortar strength is also examined. The experiments found that RHA can be used in its untreated form up to 10% as cementitious replacement without detriment of mortar compressive strength.
By using the classical Banach contraction principle, we investigate and establish stability in the sense of Ulam-Hyers and Ulam-Hyers-Rassias for random nonlinear integral equations.

Urbanization creates various challenging issues, such as air pollution, noise pollution, traffic accidents, and heat island effects. These issues have flagged up the need for solutions to enhance public health in urban environments. It is evident that urban green spaces bring about significant physical and psychological benefits. Therefore, information on their spatial distribution is crucial for urban management and planning. This paper relies on remote sensing images, collected from Sentinel-2 satellite, to preliminarily map the green space in Da Nang city.
This research work relies on kernel regression methods for constructing nonlinear regression models. These models can be used to solve function approximation tasks in construction engineering. The newly developed software program was developed with the Visual C# .NET. The program has been tested with the task of estimating the punching shear strength of steel fibre reinforced concrete slab.
Present definitions and some properties of the weak two-scale convergence (introduced by Nguetseng in 1989) for component-wise vector or matrix functions within a two-dimensional case.

This study demonstrates the application of Google OR-Tools as a powerful, easy-to-use, and open source software suite in tackling linear programs. Herein, this open source tool has been integrated with Visual C# programming and the optimization
models are formulated in Microsoft Visual Studio. Two optimization case studies are used in this study to illustrate the
implementation of the Google OR-Tools.
