  1. 1. Optimal Near-field Antenna Apertures in Lossy Media

    Author : Aidin Razavi; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal near-field aperture; near-field focusing; near-field antennas; near-field power transfer; array signal processing.; maximum penetration;

    Abstract : Antennas are traditionally designed for far-field applications such as wireless communications, radar, etc., where the antenna systems interact with other systems and objects which are located in the far-field zone of the antennas. READ MORE

  2. 2. Heating and drying wood using microwave power

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lena Antti; Luleå tekniska universitet.; [1999]

    Abstract : The potentials for moisture flux in wood during microwave heating have been investigated experimentally and theoretically. The experiments were performed in three different kinds of microwave applicators. A computer model based on the finite difference method was developed to describe and predict the heat and mass transfer. READ MORE

  3. 3. Ink-paper interaction : a study in ink-jet color reproduction

    University dissertation from Linköping : Linköpings universitet

    Author : Li Yang; Linköpings universitet.; Linköpings universitet.; [2003]

    Abstract : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. READ MORE

  4. 4. Additive Manufacturing using Alloy 718 Powder Influence of Laser Metal Deposition Process Parameters on Microstructural Characteristics

    University dissertation from Trollhättan : University West

    Author : Andreas Segerstark; Högskolan Väst.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; powder; superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Additive manufacturing (AM) is a general name used for production methodswhich have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final component is achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. READ MORE

  5. 5. Flow and Mixing of Pulp Suspensions

    University dissertation from Trollhättan : University West

    Author : Johan Pettersson; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flow behaviour; boundary-layer; Medium Consistency MC ; mixing; yield stress; suspension; pulp; Laser Doppler Anemometry LDA ; turbulence; fibre;

    Abstract : When producing pulp and paper, pulp suspensions are treated in a number of unit operations at medium consistency (MC) concentrations (3-15% by weight). Pulp suspensions at these concentrations behave as solids at low shear rates, but at sufficiently high shear rates they start to flow and can even be made to act as water. READ MORE
