  1. 26. Reversing Language Shift in Galicia : A Present-Day Perspective

    University essay from Institutionen för kultur och kommunikation

    Author : Ekaterina Skobel; [2010]
    Keywords : language; linguistics; bilingualism; Spain; Galicia; Galician; reversing language shift; minority languages;

    Abstract : The present thesis is about the current linguistic situation in the Spanish province of Galicia and about the prospects of the Galician language in modern times. The situation is analyzed through applying Joshua Fishman's model of reversing language shift (RLS). .. READ MORE

  3. 27. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Khan Fazal Ullah; [2010]
    Keywords : Aperture; Adaptive Line Enhancement ALE ; Chirp signal; Global BackProjection GBP ; Pulse compression; Radio Frequency Interference RFI ; Synthetic Aperture Radar SAR ; UltraWide Band UWB ;

    Abstract : Synthetic Aperture Radar (SAR) has many applications within ground image sensing and navigation. UltraWide Band(UWB) SAR operating at Ultra High Frequency /Very High Frequency(UHF/VHF) are usually a ffected by the Radio Frequency Interferences(RFI) from civilian communication bands which causes SIR(Signal to Interference Ratio) to go down.

  4. 28. CPM for RLS system

    University essay from Institutionen för systemteknik

    Author : Frans Bergquist; [2007]
    Keywords : CPM; RLS; kanalutjämnare; radiomodellering; simulink;

    Abstract : The main goal of this thesis is to create a continuous phase modulated radio system with a recursive least square equalizer. The two tested channel models are typical urban and rural area. The result of the performance of this radio system is displayed in Matlab plots as the bit error rate. READ MORE

  5. 29. Automatic Slip Control for Railway Vehicles

    University essay from Institutionen för systemteknik

    Author : Daniel Frylmark; Stefan Johnsson; [2003]
    Keywords : Technology; Adhesion; control; railway vehicle; slide; slip; slip velocity; rls; fuzzy logic; TEKNIKVETENSKAP;

    Abstract : In the railway industry, slip control has always been essential due to the low friction between the wheels and the rail. In this master’s thesis we have gathered several slip control methods and evaluated them. These evaluations were performed in Matlab-Simulink on a slip process model of a railway vehicle. READ MORE

  6. 30. Robust On-Line Estimation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Lars Gustafsson; Mikael Olsson; [1999]
    Keywords : Technology and Engineering;

    Abstract : In the presence if poor excitation and abrupt changes of a time-varying system the Recursive least square (RLS) with forgetting factor is not able to track the parameters in a suitable way. The purpose of this thesis is to investigate different kinds of proposals of algorithms to deal with the phenomenons arising, such as estimator windup or too slow convergence of the estimations.
