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

    Author : Aidin Razavi; Chalmers University of Technology; []
    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. Impact of Metallic Projectiles on a Ceramic Target Surface : Transition Between Interface Defeat and Penetration

    Author : René Renström; Bengt Lundberg; Patrik Lundberg; Nils-Gunnar Ohlson; Uppsala universitet; []
    Keywords : Engineering physics; Projectile; Cylindrical; Conical; Yield strength; Compressibility; Perfect flow; Self-similar flow; Interface defeat; Dwell; Teknisk fysik; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Abstract : The purpose of this thesis is to gain understanding of the load on flat target surfaces produced by projectile impact. Models are proposed from which upper and lower bounds can be derived for the transition be-tween interface defeat and normal penetration. READ MORE

  3. 3. IronArc a New Process for Pig Iron Production; a Numerical and Experimental Investigation Focusing on Mixing

    Author : Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixing time; Penetration depth; CFD simulations; IronArc; Water modeling; Mixing time Experiments; Omrörningstid; Penetrationsdjup; CFD simuleringar; IronArc; Vattenmodellering; Omrörningsexperiment; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : I den här studien så var syftet att undersöka omrörningen och relaterade fenomen i den nyutvecklade IronArc processen. Processen använder sig av gasinjektion genom plasmageneratorer för att smälta och reducera en slagg bestående av järnoxid. READ MORE

  4. 4. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Author : Gregory Makusa; Luleå tekniska universitet; []

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  5. 5. Essays on Endogenous Trade Policies

    Author : Susanna Thede; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International commerce; Internationell ekonomi; pecuniary externalities.; industry concentration; imperfect competition; strategic government interaction; maximum likelihood estimation; logit model; Bilateral trade policy; overall protection;

    Abstract : This thesis consists of a collection of essays on endogenous trade policies and may briefly be summarized as follows. The first essay empirically examines determinants of bilateral trade protection originating from normative trade theory, endogenous trade-policy studies, and political arguments put forward in the public debate.
