1. 41. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rohit Rathnam Nareshkumar; [2022]
   Keywords : Neurofeedback; Frequency domain fNIRS; vertical-cavity surface-emitting laser; silicon photomultiplier;

   Abstract : Frequency domain functional near infrared spectroscopy (FD-fNIRS) is a tissue optical measurement technique used to measure absolute haemoglobin concentrations in brain tissue. This work is intended to be the first step in the development of a wearable, low-cost FD-fNIRS device for neurofeedback applications. READ MORE

3. 42. Accuracy verification of GT-Power model and reduction of computational time

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Viktor Dahl; Maja Dyrsmeds; [2022]
   Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

   Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

4. 43. System Simulation of Electric Driveline and Active Suspension using Simcenter Amesim

   University essay from Umeå universitet/Institutionen för fysik

   Author : Simon Lundberg; [2022]
   Keywords : System Simulation; Mechatronics; Amesim; Electric driveline; Active suspension;

   Abstract : Computer simulation software’s are arguably some of the most convenient and utilized tools for an engineer as it lets them model real phenomena and observe different operations without having to perform the operation physically, thus saving both time and resources. Naturally these tools varies in design depending on their intended area of application and while a large number of them supports modeling of more than one physical domain, it is often cumbersome to attain a functional interaction between them.

5. 44. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Andreas Eriksson; [2022]
   Keywords : atmospheric dispersion; particle deposition; k-epsilon; RANS; lagrangian particle model; stochastic particle model; OpenFOAM; SIMPLE algorithm; ABL; atmospheric boundary layer; neutral boundary layer; coherent turbulent structures;

   Abstract : 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.

6. 45. The Inverse Source Problem for Helmholtz

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Hugo Fernstrom; Hugo Sträng; [2022]
   Keywords : inverse problem; inverse source problem; Helmholtz; Tikhonov regularization;

   Abstract : This paper studies the inverse source problem for the Helmholtz equation with a point source in a two dimensional domain. Given complete boundary data and appropriate discretization Tikhonov regularization is established to be an effective method at finding the point source. READ MORE
