    Sammanfattning : The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. LÄS MER

  2. 2. Experimental and numerical study of the thermal and hydraulic effect of EMC screens in radio base stations : detailed and compact model

    Detta är en avhandling från Stockholm : Kungliga Tekniska högskolan. Institutionen för energiteknik

    Författare :Raúl Antón Remírez; [2006]
    Nyckelord :sub-rack; perforated plate; air cooling; 90 degrees turn; flow deistribution; CFD; measurement;

    Sammanfattning : Today’s telecommunication cabinets use Electro Magnetic Compliance (EMC) screens in order to reduce electromagnetic noise that can cause some miss functions in electronic equipment.Many radio base stations (RBSs) use a 90-degree building architecture: the flow inlet is perpendicular to the EMC screen, which creates a complex flow, with a 90-degree air turn, expansions, compressions, perforated plates and PCBs.

  4. 4. EMC barriers measurement methodologies and model verification

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Urban Lundgren; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : The subject of Electromagnetic Compatibility (EMC) is introduced. A short overview of the regulatory EMC requirements in Europe and in the United States is presented. An explanation is given why it is important for people in the electronics business to understand the need for EMC regulations. LÄS MER

  5. 5. Intermittenta flereggsprocesser : modeller och metoder för belastningsanalys

    Detta är en avhandling från Department of Production and Materials Engineering, LTH, Lund University

    Författare :Carin Adolfsson; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; FEM; Milling; Sawing; Measurement; Model; Cutting; Force;

    Sammanfattning : This thesis presents the developement and verification of cutting force models for multi-toothed cutting processes. The scope of the thesis includes the modelling and measuring of factors that affect the mechanical load variation between individual cutting edges in the process. LÄS MER
