  1. 1. Registreringsmetoder för initial och avancerad dental erosion : Litteraturstudie

    Kandidat-uppsats,

    Författare :Nasra Hassan; Kajin Kocher; [2014]
    Nyckelord :Dental erosion; registreringsmetoder; analysering;

    Sammanfattning : Introduktion: Dental erosion definieras som förlust av tandens hårdvävnad genom en kemisk process som inte involverar bakterier. Dagens förändrade livsstil och kosthållning medför att våra tänder oftare utsätts för kemisk påverkan som kan leda till erosion. LÄS MER

  2. 2. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM; Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Hassan Sajjad; Muhammad Jamil; [2012]
    Nyckelord :Signal Processing; Fading Channel; Multi-hop;

    Sammanfattning : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

  3. 3. Construction of a setup for dispersion measurements on multilayer structures.

    Kandidat-uppsats, KTH/Tillämpad fysik

    Författare :Hassan Shah; [2012]
    Nyckelord :;

    Sammanfattning : Dispersion is a rather unavoidable phenomenon that occurs when using semiconductor, multilayer mirrors for experiments with mode-locked lasers. Due to unknown dispersion, the laser pulses may not be stable which results in unwanted laser pulse properties. LÄS MER

  4. 4. Aqueous Phase Geochemical Characterization and Delineation of Low Arsenic Aquifers in Matlab Upazila, SE Bangladesh.

    Master-uppsats, KTH/Miljögeokemi och ekoteknik

    Författare :Rajib Hassan Mozumder; [2011]
    Nyckelord :arsenic; Bangladesh; groundwater; mitigation; color tool; aquifer; highstand; lowstand;

    Sammanfattning : The fact that the former highstand whitish sediments of Plio-Pleistocene and lowstand off-white/red sediments of Late Pleistocene containing low As concentrations in the Bengal basin forms the premise for developing a color tool by the ‘Sustainable Arsenic Mitigation Project’ (SASMIT) to guide the local drillers of Matlab, SE Bangladesh, so that they can target low As aquifers. Groundwater samples collected from the black group of sediments representing a highly reducing environment contains very high concentrations of As, Fe2+ , NH4+, PO43-, HCO3–, and DOC and very low SO42- and Mn2+ concentrations; and vice-versa for the red/offwhite/white group of sediments, thus representing a less reducing condition.

  5. 5. Review of methods used for lowering groundwater levels at archeological sites, Egypt

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Dahlia S. Hassan; [2006]
    Nyckelord :Civil engineering; teknisk geografi; irrigation; groundwater table; Aswan High Dam AHD ; water-soluble salts; offshore technology; salts accumulations; Hydrogeology; geographical and geological engineering; teknisk geologi; Hydrogeologi; hydraulic engineering; soil mechanics; Väg- och vattenbyggnadsteknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Seven or eight thousand years ago, as the farthest the human memory can reach, the Egyptians established a great civilization that was considered as the origin of civilization on the Earth. There is no place in Egypt where man cannot find evidence that enlighten this civilization and tell about Egypt's role in most of the world's historic events from the beginning of mankind until the present.
