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.
In this paper, the implementation of the PZT interface technique for monitoring strand breakage in a prestressed concrete anchorage zone is presented. First, the fundamental of the PZT interface for impedance monitoring is briefly reviewed. Second, a FE (finite element) analysis of a multi-strand concrete anchorage equipped with an array of PZT interfaces is analyzed to obtain impedance signatures under a series of strand breakage events. Last, variations in impedance responses of the PZT array are quantified using root-mean-square-deviation (RMSD), and the linear tomography analysis of impedance’s RMSD indices is utilized to localize damage strands.
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.
