  1. 6. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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.

  2. 7. Amplification circuits based on electrochemical transistors

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Zia Ullah Khan; [2009]
    Nyckelord :Electrochemical transistors; Organic electronics;

    Sammanfattning : Electrochemical Transistor(ECT) was reported by David Nilsson in 2002. Later,its dimensios were specified and a SPICE model was developed.The main purpose of this diploma work is to check the performance of electrochemical transistors in amplifier circuits. Simple amplifier circuits were simulated using SPICE model of ECT. LÄS MER

  3. 8. Exploring the Accuracy of Existing Effort Estimation Methods for Distributed Software Projects-Two Case Studies

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation; Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Abid Ali Khan; Zaka Ullah Muhammad; [2009]
    Nyckelord :Effort Estimation; Global Software Development GSD ; COCOMO II; SLIM; ISBSG;

    Sammanfattning : The term “Globalization” brought many challenges with itself in the field of software development. The challenge of accurate effort estimation in GSD is one among them. When talking about effort estimation, the discussion starts for effort estimation methods. There are a number of effort estimation methods available. LÄS MER

  4. 9. SWOT Analysis of IP Multimedia Sub System Security Authentication Schemes

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem; Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Syed Majid Ali Shah Bukhari; Inayat Ullah Khan; [2009]
    Nyckelord :SWOT Analysis; IMS; Security Authentication. ;

    Sammanfattning : SWOT analysis is performed on IMS security authentication schemes to demonstrate the effectiveness of each schemes in terms of multiple parameters and associated dependencies for users and network operators. Due to SWOT tool we have been able to describe strengths, weakness, opportunities and threats in each authentication scheme separately. LÄS MER
