1. 1. Integrated Lumped Element and Ferroelectrically Tunable Microwave Components

   Författare :Dan Kuylenstierna; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lumped; Passive element; metamaterial; periodic structure;

   Sammanfattning : This thesis treats the development of passive circuits for increased integrationlevel in microwave front-ends. The subject is approached from twodifferent directions. On the one hand, emerging materials for microwaveintegrated circuits are studied. On the other hand, novel circuit topologiesare synthesized. LÄS MER

3. 2. Dynamic response reconstruction using passive components

   Författare :Anders Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

   Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER

4. 3. Intermodulation Distortion in Active and Passive Components

   Författare :Martin Mattsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermodulation distortion; hyperabrupt junction; polynomial model; passive intermodulation; nonlinear analysis; loaded-line phase shifter; varactor modeling;

   Sammanfattning : Wireless communication is growing rapidly, and the demand for higher data rate, low latency, and availability leads to a more complex infrastructure with new challenges. Multiple communication systems have to co-exist in a densely populated frequency-spectrum, where higher power levels and more sensitive receivers are required. LÄS MER

5. 4. Stochastic finite element simulations of real life frontal crashes : With emphasis on chest injury mechanisms in near-side oblique loading conditions

   Författare :Johan Iraeus; Mats Lindquist; Ulf Björnstig; Mats G Larsson; Joel Stitzel; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EDR; Real life crashes; Oblique; Finite element; Simulation; HBM; Injury mechanism; Pulse shape; Stochastic; Rib fracture; THUMS; Generic; Statistics; biomechanics; biomekanik; skadeförebyggande; injury prevention;

   Sammanfattning : Introduction. Road traffic injuries are the eighth leading cause of death globally and the leading cause of death among young people aged 15-29. Of individuals killed or injured in road traffic injuries, a large group comprises occupants sustaining a thorax injury in frontal crashes. The elderly are particularly at risk, as they are more fragile. LÄS MER

7. 5. (De)composing the middle : A minimalist approach to middles in English and Swedish

   Författare :Eva Klingvall; Engelska; []
   Nyckelord :HUMANIORA; HUMANITIES; passive; argument structure; past participle; Distributed Morphology; root; agentivity; middle; genericity; disposition ascription; modification; grammatical features; verbal alternation;

   Sammanfattning : This thesis is concerned with a particular type of generic sentence that is referred to as the ‘middle construction’ in the literature. The aim of the thesis is to offer a theoretical account of middles couched within the non-lexicalist framework of Distributed Morphology (see Halle & Marantz 1993 and subsequent work), and, more generally, within the Minimalist Program (see e.
