1. 1. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Torpikay Azizi; [2023-08-18]
   Keywords : PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

   Abstract : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. READ MORE

3. 2. Infrared and Visible Image Fusion with an Unsupervised Network

   University essay from Linköpings universitet/Datorseende

   Author : Matilda Granqvist; [2023]
   Keywords : Machine learning; Image processing; Image fusion; CNN;

   Abstract : Image fusion is a technique that aims to combine semantic information from different source images into a new synthesized image that contains information from both source images. It is a technique that can be useful in many different areas, such as reconnaissance, surveillance and medical diagnostics. READ MORE

4. 3. Detecting defects on cheese using hyperspectral image analysis

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonathan Palmquist; [2020]
   Keywords : ;

   Abstract : Defects such as mold and bacterial stains can appear on cheese. Manually detecting defects is a time-consuming, cost-ineffective, and ergonomically unsatisfactory process for a dairy because the quality technicians must inspect each cheese before packaging. READ MORE

5. 4. Forest stand delineation through remote sensing and Object-Based Image Analysis

   University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

   Author : José Antonio Ortega-García; [2018]
   Keywords : forest stand; stand delineation; LiDAR; ASTER; OBIA; GIS; remote sensing; segmentation; canopy heigh model; forestry; Navarra; OBIA; LiDAR; ASTER; segmentación; rodal; forestal; SIG; teledetección;

   Abstract : Forest stand delineation is an essential task of forest management planning which can be time consuming and exposed to subjectivity. The increasing availability of LiDAR data and multispectral imagery offers an opportunity to improve stand delineation by means of remotely-sensed data. READ MORE

6. 5. Effects of different biochar application rates on soil fertility and soil water retention in on-farm experiments on smallholder farms in Kenya

   University essay from SLU/Dept. of Soil and Environment

   Author : Helene Puehringer; [2016]
   Keywords : biochar; soil water retention; bulk density; macro nutrient availability; VNIR; maize cobs and stover; coffee husk;

   Abstract : Biochar is produced through pyrolysis, the thermo-chemical degradation of biomass under anaerobic or oxygen-limited conditions. Due to its properties related to surface area and porosity, bulk density, nutrient content, stability, cation exchange capacity (CEC), pH value, and carbon content, biochar has the potential to improve physical as well as chemical soil properties and thus improve crop productivity and contribute to carbon sequestration.
