2. 1. Effective vibro-acoustical modelling of rubber isolators

   Author : Michael Coja; Leif Kari; Wolfgang Kropp; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; Rubber isolator; Bush mounting; Dynamic stiffness; Waveguide; Fractional derivatives; Mode-matching; Pre-compressed; Prestrain; Preload; Predeformation; Viscoelasticity; Dispersion; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : This thesis, gathering four papers, concerns the enhancement in understanding and modelling of the audible dynamic stiffness of vibration rubber isolators including experimental measurements. Paper A studies the performances of three different types of vibration isolator using an indirect measurement technique to estimate the blocked dynamic transfer stiffness of each specimen. READ MORE

4. 2. Implementation of Flash Analog-to-Digital Converters in Silicon-on-Insulator Technology

   Author : Erik Säll; Mark Vesterbacka; Bengt E. Jonsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flash analog-to-digital converter; ADC; silicon-on-insulator; SOI; top-down design; dynamic element matching; DEM; thermometer-to-binary encoder; flash ADC modeling; Electronics; Elektronik;

   Abstract : High speed analog-to-digital converters (ADCs) used in, e.g., read channel and ultra wideband (UWB) applications are often based on a flash topology. The read channel applications is the intended application of this work, where a part of the work covers the design of two different types of 6-bit flash ADCs. READ MORE

5. 3. Alloy element redistribution during sintering of powder metallurgy steels

   Author : Abdul Malik Tahir; Gustav Amberg; Jose Manuel Torralba; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cu redistribution kinetics; diffusion; phase field modeling; powder metallurgy; swelling; liquid phase sintering; Teknisk materialvetenskap; Materials Science and Engineering; Engineering Mechanics; Teknisk mekanik;

   Abstract : Homogenization of alloying elements is desired during sintering of powder metallurgy components. The redistribution processes such as penetration of liquid phase into the interparticle/grain boundaries of solid particles and subsequent solid-state  diffusion of alloy element(s) in the base powder, are important for the effective homogenization of alloy element(s) during liquid phase sintering of the mixed powders.

6. 4. Stochastic model updating and model selection with application to structural dynamics

   Author : Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

   Abstract : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

7. 5. Studies on performance limitations in CMOS DACs

   Author : K. Ola Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The digital-to-analog converter (DAC) is a bottle neck in broadband communication systems. High update rates are required in combination with high accuracy. READ MORE
