  1. 11. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Cecilia Borghero; [2018]
    Keywords : SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Abstract : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. READ MORE

  3. 12. Lunar Light House

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Monika Lipinska; [2018]
    Keywords : architecture; space; space architecture; moon; lunar; light house; cellulose; nano-cellulose; moon base; lunar outpost; Arts and Architecture;

    Abstract : The Lunar Light House project was developed to provide a novel system of protection against cosmic radiation specifically for a surface Lunar base. It’s main target was to find a technical solution which would allow for more freedom in shaping the base structure and also potentially for introducing natural sun light. READ MORE

  4. 13. Thermal cracking of a concrete arch dam due to seasonal temperature variations

    University essay from KTH/Betongbyggnad

    Author : Jonas Enzell; Markus Tollsten; [2017]
    Keywords : Arch dam; Concrete; Finite element analysis; Cracking; Progressive failure analysis; Valvdamm; Betong; Finit elementanalys; Sprickor; Progressiv brottanalys;

    Abstract : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. READ MORE

  5. 14. Crest Factor Reduction using High Level Synthesis

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Hassan Mahmood; [2017]
    Keywords : Peak to average power ratio; Crest factor; Peak cancellation crest factor reduction; High level synthesis; Design space exploration; Object oriented programming; SystemC; Skillnad mellan maximal effekt och medeleffekt; Toppfaktor; Algoritmen peak cancellation; Högnivåsyntes; SystemC; Undersökningen av designalternativ; Objektorienterad programmering;

    Abstract : Modern wireless mobile communication technology has made noticeable improvements from the technologies in the past but is still plagued by poor power efficiency of power amplifiers found in today’s base stations. One of the factors that affect the power efficiency adversely comes from modern modulation techniques like orthogonal frequency division multiplexing which result in signals with high peak to average power ratio, also known as the crest factor.

  6. 15. An efficient Hardware implementation of the Peak Cancellation Crest Factor Reduction Algorithm

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Matteo Bernini; [2016]
    Keywords : CFR; PC-CFR; PAPR Reduction; OFDM; CFR; PC-CFR; PAPR Reduction; OFDM;

    Abstract : An important component of the cost of a radio base station comes from to the Power Amplifier driving the array of antennas. The cost can be split in Capital and Operational expenditure, due to the high design and realization costs and low energy efficiency of the Power Amplifier respectively. READ MORE
