11. Constructing an optical tweezers instrumentation and evaluation of trapping stiffness using the power spectrum method
University essay from Umeå universitet/Institutionen för fysikAbstract : Optical tweezers can trap micron-sized objects such as cells, bacteria, and microspheres, and has become an important instrument for measuring forces associated with various physical and biological phenomena. In this thesis work, I constructed an optical tweezers instrument to trap 2µm diameter beads using a HeNe-laser operating with a wavelength of 632. READ MORE

12. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications. The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

13. Viability Evaluation of the Turtle Trading Rules on Major Market Indexes
University essay from KTH/Matematik (Avd.)Abstract : The Turtle Trading Rules was a successful trend-following trading strategy for commodities in the 1980s but has lost recognition in recent days. The strategy revolved around rules for entering and exiting trades as well as position sizing for each trade. READ MORE

14. Cell-sorting in grid-based time-continuous cell population models
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : This thesis extends an existing cell population modelling framework to investigate two different hypotheses for what drives the phenomenon of cell sorting, which is the spontaneous self-reorganization of cell populations. This behaviour cause cells to find their way back into their original configuration after they have been scrambled. READ MORE

15. Investigating the Statistical Properties of the Hurst Exponent Estimator of Rough Volatility Model
University essay from Göteborgs universitet/Graduate SchoolAbstract : The aim of this thesis is to provide a characterization of the statistical properties of estimator of the Hurst parameter of the rough stochastic volatility model following fractional Brownian motion with Hurst index H. For this purpose, we perform a simulation experiment for fractional Brownian motion based on the circulant embedding method. READ MORE
