To address this issue, in this study, the authors have put forth a novel set of parameters that can be used to evaluate the reduction in stiffness of spans over time. The stiffness is a critical factor that determines its structural integrity, and it is essential to monitor any changes in this parameter over the lifespan of the bridge.

The purpose of the study "Monitoring surface water bodies changes from sentinel-2A imagery with modified normalized difference water index: Application in Dalat, Lam Dong, Viet Nam" is to identify surface water body changes using Sentinel-2 MSI (Multi-Spectral Instrument) data, one of the latest types of remote sensing satellite data. The results of the research show that by using Sentinel-2 MSI imagery, MNDWI (Modified Normalized Water Index) is the appropriate parameter to detect surface water areas in the studied area, with an overall accuracy > 0.92 and Kappa coefficient > 0.84.

In this work, we study the generation of a negative refractive index based on electromagnetically induced transparency (EIT) in a Rb four-level N-type atomic gas medium. We derive analytic expressions for the relative permittivity and relative permeability of the medium according to the parameters of the probe, pump, and signal laser fields.

The study objective was to assess chaotic global metrics in malnourished children following power spectral manipulations. Methods: We evaluated the complexity of heart rate (HR) variability (HRV) in malnourished subjects via six power spectra (Welch, multi-taper method (MTM), Burg, covariance, YuleWalker, and periodogram) and then, when adjusted by the MTM parameters, for further refinement.

In this paper we consider spectral properties of the operator pencils generated by boundary-value problems for second order elliptic equation depending parameter in a plane angle. We receive explicit formula for the eigenvalues and the eigenvectors of the operator pencil, the multiplicity of the eigenvalues, and the differentiability of the eigenvalues and the eigenvectors with respect to the parameter.

In this study, we present the technique of tunable diode laser spectroscopy and the spectroscopic parameters of 13 lines of H2O in the 11980 -12260 cm−1 spectral region. Spectra were recorded at room temperature for a wide range of pressures (2 - 15 Torr for pure H2O and 50 - 760 Torr for H2O in air).

Inorganic or inorganic-organic hybrid nanomaterials have great potential for applications in the biomedical fields. Biological half-life is an essential pharmacokinetic parameter for these materials to function in vivo. Compared to inductively coupled plasma mass spectrometry (ICP-MS), which is the gold standard, laser-induced breakdown spectroscopy (LIBS) is a faster and more efficient elemental detection method. We investigated an efficient way to quantify the metabolic rate using LIBS.

Based on the analysis of ocean wave data sets of this province the significant height of 3.854 m and peak period of 9.807 s were obtained. Those can be used to determine the wave class based on the environmental information’s, and the appropriate type of spectral model to use in the study of ocean wave energy converters for energy harvesting.

The object-oriented image analysis delineates segments of homogeneous image areas. The delineated segments are classified to real world objects based on spectral, textural, neighbourhood an object specific shape parameter. Object-oriented classification of highresolution imagery is a challenging job for the remote sensing community. Identification of the object-oriented classes based on objects leads to better classification. In this project, the object-oriented classification for tomato in Shoolagiri and surrounding villages of Krishnagiri district in Tamil Nadu, India.

Object Based classification involves grouping of pixels based on spatial relationships like similar colour, tone, Shape with surrounding pixels. Object-based information extraction depends on spectrum character and geometry and structure information. Object based classification interprets an image that is represented not only by a single pixels, but also in meaningful image objects and their mutual relationships. In this study has been attempted mapping of coconut growing areas for Kozhikode taluk, Kerala.

The analysis of the spectral properties and dynamic evolution of a CME/shock event observed on November 1st 2003 in white-light by the LASCO coronagraph and in the ultraviolet by the UVCS instrument operating aboard SOHO, has been performed to compute the properties of some important plasma parameters in the middle corona below about 2Rx. Simultaneous observations obtained with the MLSO/Mk4 white-light coronagraph, providing both the early evolution of the CME expansion in the corona and the pre-shock electron density profile along the CME front, were also used to study this event.

The photocatalytic decoloration of an organic dye, ethyl violet (EV), has been studied in the presence of TiO2 and the addition of b-Cyclodextrin (b-CD) with TiO2 (TiO2-b-CD) under UV-A light irradiation. The different operating parameters like initial concentration of dye, illumination time, pH and amount of catalyst used have also been investigated. The photocatalytic decoloration efficiency is more in the TiO2-b-CD/UV-A light system than TiO2/UV-A light system. The mineralization of EV has been confirmed by Chemical Oxygen Demand (COD) measurements.
