The concept of sustainable tourism first emerged in 1992. Are more than 30 years on a journey towards establishing sustainable values, we have shown signs of perplexity in various aspects, focusing on issues such as: Whose responsibility it is, how it should be implemented, and how it can be measured.

Cables in cable-stayed bridges have low intrinsic damping, and dampers are often used as a countermeasure for cable vibration control. This paper presents an innovative asymptotic formula for calculating the additional damping in stay cables equipped with Negative Stiffness High Damping Rubber dampers (NS-HDR).

The rest of the paper is organized as follows: In the next section, we recall the concept of picture fuzzy set and several operators of two picture fuzzy sets. We then propose a new MCDM method using the dissimilarity measure of picture fuzzy sets. Finally, we apply the proposed method for evaluating water reuse applications.

In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

In this study, platinum (Pt) microelectrodes are modified with electrochemically reduced graphene oxide (ERGO) using a simple and effective protocol. These Pt/ERGO microelectrodes are able to be used as electrochemical sensors for direct and rapid detection of ascorbic acid (AA) in aqueous solutions using linear sweep voltammetry (LSV) measurements.

This study focuses on the synthesis of V-doped TiO2 materials using a modified polyol method to enhance their efficiency. The obtained materials were characterized by various methods such as XRD, EDX, FTIR, SEM, TEMSAED, Raman, and UV-Vis DRS. The results indicated the crystalline anatase phase of TiO2, with spherical morphology and an average size of 30nm. The UV-DRS measurement demonstrated that doped materials have a lower bandgap than the pristine TiO2.

This study presents a preliminary investigation on using pristine aluminum particles as anodes for lithium-ion battery. The microstructural characteristics of aluminum particle samples with sizes from 100 nm (0.1 μm) to 70 µm were analyzed by the SEM and XRD methods. The electrochemical behaviors of the aluminum particles were examined by the cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) measurements.

In the present report, a novel concept of frequency response function (FRF) is introduced for piezoelectric beam. First, a model of Timoshenko beam bonded with a piezoelectric layer is established and used for deriving the conventional frequency response function acknowledged as mechanical frequency response function (MERF). Then, the output charge produced in the piezoelectric layer is calculated from the MFRF and therefore obtained frequency-dependent function is called electrical frequency response function (EFRF) for the integrated beam.

This study utilized the GIS-based Soil and Water Assessment Tool (SWAT) model to simulate the flow of Vu Gia - Thu Bon river basin at two hydrological stations - Nong Son and Thanh My, during the calibration period (2004 - 2010) and the verification period (2011 - 2015). The evaluation results of both periods, as measured by the NSE and R2 indexes, were found to be above 0.75.
