    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The data traffic in wireless networks has grown tremendously over the past few decades and is ever-increasing. Moreover, there is an enormous demand for speed as well. LÄS MER

  3. 2. Frequency Recognition Algorithm for Multiple Exposures : Snapshot imaging using coded light

    Författare :Karolina Dorozynska; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Snapshot imaging; structured illumination; structured light; multispectral; fluorescence; frequency encoding; image multiplexing; lock-in detection; Fysicumarkivet A:2020:Dorozynska;

    Sammanfattning : The central challenge tackled in this thesis is the development of an optical imaging approach capable of multidimensional image capture of dynamic samples. Many conventional optical imaging approaches, which can obtain dimensional information such as spectral, polarisation, or volumetric, to name a few, about samples either employ sequential image capture or parallelised detector arrangements.

  4. 3. Multiplexing Methods for Surface-Stabilized Ferroelectric Liquid Crystal Devices

    Författare :Tomasz Matuszczyk; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present thesis deals with the electronic addressing of Surface-Stabilized Ferroelectric Liquid Crystal (SSFLC) displays. Basically, this means to investigate how a certain information can be produced serially in the shape of long square pulse waveforms and transferred to a high resolution SSFLC matrix, via the specific linear electro-optic response exhibited by this material, to form a desired image on the screen at any time.

  5. 4. Blind Massive MIMO Base Stations : Downlink Transmission and Jamming

    Författare :Marcus Karlsson; Erik G. Larsson; Emil Björnson; Ralf Müller; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Massive MIMO (Multiple-Input--Multiple-Output) is a cellular-network technology in which the base station is equipped with a large number of antennas and aims to serve several different users simultaneously, on the same frequency resource through spatial multiplexing. This is made possible by employing efficient beamforming, based on channel estimates acquired from uplink reference signals, where the base station can transmit the signals in such a way that they add up constructively at the users and destructively elsewhere.

  7. 5. Visual and magnetic detection of antimicrobial resistance genes using nanoparticles and isothermal amplification

    Författare :Darío Sánchez Martín; Teresa Zardán Gómez de la Torre; Maria Strömme; Mahiar Hamedi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA amplification; isothermal amplification; visual detection; nanoparticles; VAM-NDA; rolling circle amplification; phi29 DNA polymerase; padlock probes.; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Antibiotic resistance is becoming an increasing concern, necessitating new ways to diagnose and treat it rapidly and accurately. One proposed solution is the use of nucleic acid amplification tests, capable of detecting resistance in just a few hours, as opposed to the several days that traditional testing methods may require.
