  2. 1. Evaluating the performance of TEWA systems

    Author : Fredrik Johansson; Göran Falkman; Lars Karlsson; Lars Niklasson; Martin Holmberg; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; air defense; information fusion; performance evaluation; threat evaluation; TEWA; weapon allocation; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Datalogi; Computer and Systems Science; Teknik;

    Abstract : It is in military engagements the task of the air defense to protect valuable assets such as air bases from being destroyed by hostile aircrafts and missiles. In order to fulfill this mission, the defenders are equipped with sensors and firing units. To infer whether a target is hostile and threatening or not is far from a trivial task. READ MORE

  4. 2. Growth and Characterization of ZnO Nanocrystals

    Author : Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Abstract : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. READ MORE

  5. 3. The open absorption system : energy savings in different applications

    Author : Lars Johansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.

  6. 4. Impregnation of concrete structures : transportation and fixation of moisture in water repellent treated concrete

    Author : Anders Johansson; Johan Silfwerbrand; Lars-Olof Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Abstract : Water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE

  7. 5. Shape stability of laminated veneer products

    Author : Lars Blomqvist; Dick Sandberg; Jimmy Johansson; Magdalena Sterley; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adhesive; beech; birch; bending; laminated veneer products; moulding; shape stability; spring-back; twist; veneer; Forestry and Wood Technology; Skog och träteknik;

    Abstract : This thesis is about the shape stability of laminated veneer products.Laminated veneer products consist of veneers bonded together with adhesive into a predetermined shape. Such products are used in several contexts but especially in furniture manufacture. READ MORE
