1. 1. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Svante Rosenlind; [2023]
   Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

   Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

3. 2. Multi-Channel Sentiment Analysis in Swedish as Basis for Marketing Decisions

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

   Author : Malin Uhlander; [2023]
   Keywords : omni-channel marketing; sentiment analysis; Swedish; natural language processing; opinion mining;

   Abstract : In today’s world, it is not enough for companies to consider any one social media channel in isolation. Instead, they must provide their customers with a unified experience across channels and consider interdependencies between channels. READ MORE

4. 3. Elastic Net Regression for Prosthesis Control in Short Residual Limb Amputees: Performance and Generalizability

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Oskar Berg; [2023]
   Keywords : Neuroengineering; Statistics; Biomedical Signal Processing; Technology and Engineering;

   Abstract : This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-DOF isometric forces outputs from fingers and the wrist.
