1. 1. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Marie-Ange Stefanos; [2023]
   Nyckelord :Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

   Sammanfattning : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

3. 2. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Máté Károly Tóth; [2023]
   Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

4. 3. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Alfred Norberg; [2023]
   Nyckelord :Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

   Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

5. 4. EDPM : An extension of EDPM - an embedded domain-specific language for performance monitoring C and C++ programs

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :David Bosnjak; [2023]
   Nyckelord :EDPM; Dynamic Nesting; PAPI; LLVM; Libtooling; EDPM; Dynamisk Nestning; PAPI; LLVM; Libtooling;

   Sammanfattning : Background. Performance monitoring of C/C++ programs has often been a tedious and straining process, where insufficient and complex tools/APIs are required. Performance monitoring tools and APIs tend to focus on ease of use or flexibility, but rarely both. LÄS MER

7. 5. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Saga Westerberg; [2023]
   Nyckelord :Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

   Sammanfattning : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index. LÄS MER
