1. 1. Automated Quantitative Phase Imaging Pipeline : for Monitoring Bacterial Cell Growth under Chemical Influence

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Samuel Zargani; [2023]
   Keywords : image analysis; QPI; Quantitative Phase Imaging; QLSI; kvantitativ fasavbildning; Bildanalys;

   Abstract : Bacteria have a vital role in ecosystems and the human health. However, the effect of environmental pollution on them at the single-cell level are still not well understood. Label-free imaging has become increasingly important within science. It has allowed for the visualization of cells without the use of molecular tools or labels. READ MORE

3. 2. Data acquisition system for optical frequency comb spectroscopy

   University essay from Umeå universitet/Institutionen för fysik

   Author : Ragnar Seton; [2017]
   Keywords : DAQS; HITRAN; MATLAB; libmx; Fourier Transform Spectrometry; Real time data visualization;

   Abstract : The Optical Frequency Comb Spectroscopy (OFCS) Group at the Department of Physics at Umeå University develops new techniques for extremely high sensitivity trace gas detection, non invasive temperature measurements, and other applications of OFCS. Their setup used primarily for trace gas detection contains several components that have been developed in-house, including a Fourier Transform Spectrometer (FTS) and an auto-balancing detector.

4. 3. Wisdom-volkano : a novel tool based on open GIS and time-series to analyse and share volcanic data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Fulgencio Sanmartín; [2016]
   Keywords : GIS; volcanic eruption; interferogram; time-series; seismology; GNSS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

   Abstract : Active volcanoes threaten life around. In order to predict their eruptions earlier and mitigate their hazards, several variables must be observed and compared. Geographical information systems (GIS) combine different geospatial images from remote or local sensing. However, GIS often miss how maps change during the time. READ MORE

5. 4. Ground-Based Synthetic Aperture Radar Data processing for Deformation Measurement

   University essay from KTH/Geodesi och satellitpositionering

   Author : Andreas Jungner; [2009]
   Keywords : ;

   Abstract : This thesis describes a first hands-on experience working with a Ground-Based Synthetic Aperture Radar (GB-SAR) at the Institute of Geomatics in Castelldefels (Barcelona, Spain), used to exploit radar interferometry usually employed on space borne platforms. We describe the key concepts of a GB-SAR as well as the data processing procedure to obtain deformation measurements. READ MORE

6. 5. Processing SAR data using RangeDoppler and Chirp Scaling Algorithms

   University essay from KTH/Geodesi och satellitpositionering

   Author : Naeim Dastgir; [2007]
   Keywords : ;

   Abstract : Applications of self-illuminating remote sensing systems, and among those, Radar Imagery is growingrapidly. Unique properties of Synthetic Aperture Radar (SAR) system makes it one of the most popularand applicable methods of self illuminating remote sensing techniques for ground deformationmonitoring, seismic studies, and many photogrammetry applications.
