1. 1. Microfluidics for High-Pressure Inertial Focusing : Focusing, Separation and Concentration of Micro and Sub-micron Particles

   Författare :Javier Cruz; Klas Hjort; Aman Russom; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microsystems; Microfluidics; Inertial Focusing; Particle Manipulation; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Sammanfattning : The birth of microsystems set the ground for technologies never imagined before, for it is not only the small size what characterizes the miniaturized systems, but unique phenomena arise in the micro scale. This thesis relates to one such unique phenomenon, inertial focusing, a phenomenon that occurs in microfluidic systems if very special conditions are met and that allows for fine manipulation of particles in fluid samples.

3. 2. Bayesian Inference for Nonlinear Dynamical Systems : Applications and Software Implementation

   Författare :Jerker Nordh; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Indoor Navigation; pyParticleEst; Software Implementation; Simultaneous Localization and Mapping; Parameter Estimation; System Identification; Sequential Importance Sampling; Particle Filter; Bayesian Inference; Markov Chain Monte Carlo; Particle Smoother;

   Sammanfattning : The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. LÄS MER

4. 3. Point of care microfluidic tool development for resource limited settings

   Författare :Indradumna Banerjee; Aman Russom; Luca Brandt; Gustaf Mårtensson; Jens Ducrée; KTH; []
   Nyckelord :Blood; control; cell separation; centrifugal microfluidics; diagnostics; elasto-inertial; hematocrit level; microfluidics; neonatal diagnostics; nucleic acid quantification; point of care; particle focusing; resource limited settings.; Bioteknologi; Biotechnology;

   Sammanfattning : The development of point of care diagnostics using recent advances in microfluidics have the potential to transform health care in several ways, especially in resource limited settings with limited access to advanced health care infrastructure. However, translating a point of care device to reality is often a challenging task because of the complexities involved in integrating a number of diverse engineering concepts into an easy to use, accurate and portable device.

5. 4. Orientation of elongated, macro and nano-sized particles in macroscopic flows

   Författare :Karl Håkansson; Danel Söderberg; Fredrik Lundell; Lisa Prahl Wittberg; Jean-Yves Cavaillé; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orientation; fibre; fibril; turbulent channel flow; particle streaks; flow focusing; cellulose nanofibrils; extensional flow; Smoluchowski; rotary diffusion;

   Sammanfattning : Non-spherical particles are present all around us, in biological, industrial and environmental processes. Making predictions of their impact on us and systems in our vicinity can make life better for everyone here on earth. LÄS MER

7. 5. Laser-Matter Interactions at Extreme Irradiance: X-ray Generation and Relativistic Channelling

   Författare :Anders Sjögren; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relativistic self-focusing; particle acceleration; x-ray generation; radiography; Laserteknik; Laser technology; laser-produced plasma; light scattering; Fysicumarkivet A:2002:Sjögren;

   Sammanfattning : This thesis summarizes experimental work in which the powerful Ti:sapphire lasers at the High Power Laser Facility at the Lund Laser Centre have been employed to investigate laser-produced X-rays and relativistic channelling. These lasers produce short pulses, of the order of 50 fs, with energies ranging from 1 mJ to 1 J. LÄS MER
