1. Approach for frequency response-calibration for microphone arrays
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. LÄS MER
2. Storage period optimization of a viscous nasal spray suspension
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. LÄS MER
3. Digital Microwave Control of Superconducting Qubits
Master-uppsats, KTH/Tillämpad fysikSammanfattning : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. LÄS MER
4. Electrical Impedance Profiling of Plants, Coffee and TREO
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och systemSammanfattning : The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.

5. CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE : CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE
Master-uppsats, Umeå universitet/Kemiska institutionenSammanfattning : Microfibrillated cellulose (MFC) films have gained a lot of industrial interest lately dueto their good barrier properties and good mechanical strength. In this study it wasinvestigated whether rheological characteristics and conductivity of MFC dispersionscomprised of different MFC grades could be correlated to tensile properties of the MFCfilms produced from the corresponding MFC dispersion.
