  1. 21. Rosetta Langmuir probe performance

    University essay from Institutionen för fysik och astronomi

    Author : Fredrik Johansson; [2013]
    Keywords : Rosetta; SPIS; SPIS 5; Langmuir; Probe; Plasma; Probe sweep; Potential; Simulation; PIC; IRF; Swedish Institute of Space Physics; ESA;

    Abstract : Several Langmuir probe voltage sweeps by a model of the ESA spacecraft Rosetta was simulated in a plasma with solar wind parameters using the ESA open source software SPIS 5. The simulations were carried out to in- vestigate the features of the spacecraft’s environment in the solar wind and the effect of photoemission from the spacecraft surface on the measurements made by the Langmuir probes on board Rosetta.

  3. 22. WIDE-BANDWIDTH TIME OF FLIGHT SPECTROSCOPY OF TURBID MEDIA

    University essay from Lunds universitet/Atomfysik

    Author : Arman Ahamed Subash; [2012]
    Keywords : WIDE-BANDWIDTH; TIME OF FLIGHT; SPECTROSCOPY; TURBID; Physics and Astronomy;

    Abstract : Wide bandwidth time-of-flight spectrometer (TOFS) developed in the Group of Biophotonics,Lund University, is a unique tool which is capable to deliver continues absorption/scattering spectra of turbid samples in a singularly broad wavelength range from 600nm up to 1400nm. The main focus of this thesis work is to calibrate and optimize the performance of the instrumental setup of this system for biomedical & pharmaceutical applications ensuring the capability to produce results with high accuracy and repeatability.

  4. 23. Do crude oil price changes affect economic growth of India, Pakistan and Bangladesh? : A multivariate time series analysis

    University essay from Nationalekonomi

    Author : Muhammad Akram; [2012]
    Keywords : Oil price shocks; Economic growth; Vector Autoregressive; Impulse response function; Wald Granger causality test;

    Abstract : This paper analyzes empirically the effect of crude oil price change on the economic growth of Indian-Subcontinent (India, Pakistan and Bangladesh). We use a multivariate Vector Autoregressive analysis followed by Wald Granger causality test and Impulse Response Function (IRF). READ MORE

  5. 24. Determination of Ion Number Density from Langmuir Probe Measurements in the Ionosphere of Titan

    University essay from Institutionen för teknikvetenskaper

    Author : Oleg Shebanits; [2010]
    Keywords : ion number distribution; titan; ionosphere; langmuir;

    Abstract : Saturn’s largest moon, Titan, presents a very interesting subject for study because of its atmosphere’s complex organic chemistry. Processes taking place there might shed some light on the origins of organic compounds on Earth in its early days. READ MORE

  6. 25. Synthetic Aperture Radar Image Quality Measurements

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Subrata Kumar Das; [2010]
    Keywords : Key Words: SAR; UWB SAR; spatial resolution; differential resolution; ISLR; PSLR; sinc function; IRF-SAR.;

    Abstract : Abstract Synthetic Aperture Radar (SAR) is an important tool for remote sensing now a day. SAR image quality measurements play an important role in the development of SAR image digital processing methods. The essential SAR image quality assessments are spatial resolutions, Integrated Sidelobe Ratio (ISLR) and Peak Sidelobe Ratio (PSLR). READ MORE
