A Seasonal Investigation on Land Surface Temperature and Spectral Indices in Imphal City, India

open access: yesJournal of Landscape Ecology, 2022
The study focused on investigating the seasonal and spatiotemporal relationship between the relationships of LST with four spectral indices (MNDWI, NDBaI, NDBI, and NDVI) in and around Manipur City of India using eight cloud-free Landsat data from the ...

Detection of historical landscape changes in Lake Victoria Basin, Kenya, using remote sensing multi-spectral indices

open access: yesWatershed Ecology and the Environment, 2022
The Kenyan Lake Victoria basin has been experiencing land degradation and overexploitation as seen in various landscape changes. Quantifying and understanding the nature of these changes is essential for management decision-making.

Geometry of the Nonabelian DBI Dyonic Instanton [PDF]

open access: yes, 2000
We introduce a calculus of the Lie algebra valued functions present in Tseytlin's proposal for the nonabelian DBI action, and apply it to show that the recently found dyonic instanton is a solution of the full nonabelian DBI action.

Structural phase transition and electronic properties of NdBi

open access: yesAIP Conference Proceedings, 2015
The structural and electronic properties of NdBi from an electronic structure calculation have been presented. The calculation is performed using self-consistent tight binding linear muffin tin orbital (TB-LMTO) method within the local density approximation (LDA). The calculated equilibrium structural parameters are in good agreement with the available

Trispectrum estimator in equilateral type non-Gaussian models [PDF]

open access: yes, 2010
We investigate an estimator to measure the primordial trispectrum in equilateral type non-Gaussian models such as k-inflation, single field DBI inflation and multi-field DBI inflation models from Cosmic Microwave Background (CMB) anisotropies.

Downscaling landsat land surface temperature over the urban area of Florence [PDF]

open access: yes, 2016
A new downscaling algorithm for land surface temperature (LST) images retrieved from Landsat Thematic Mapper (TM) was developed over the city of Florence and the results assessed against a high-resolution aerial image.

Normalized Dryness Built-up Index (NDBI) to Detect Settlement Change In Buleleng Sub-District

open access: yesMedia Komunikasi FPIPS, 2021
This research aims to find out the development of settlements that occur over the next 20 years. Monitoring the development of settlements is carried out by remote sensing methods using Landsat 7 ETM+ imagery and Landsat 8 OLI imagery. Landsat 7 ETM+ used in 2000, and Landsat 8 OLI used in 2019.

A COMPARATIVE STUDY OF LAND SURFACE TEMPERATURE WITH DIFFERENT INDICES ON HETEROGENEOUS LAND COVER USING LANDSAT 8 DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
The temperature rise in urban areas has become a major environmental concern. Hence, the study of Land surface temperature (LST) in urban areas is important to understand the behaviour of different land covers on temperature.
