1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER
2. Data Complexity and its effect on Classification Accuracy in Multi Class Classification Problems : A study using synthetic datasets
Kandidat-uppsats, KTH/DatavetenskapSammanfattning : This study investigates how the performance of a selection of machine learning classifiers is affected by the data complexity, measured by F1, N1, N2, and N3 in a multi class classification setting. This study uses synthetic datasets that span across the range of possible complexity levels for each complexity measure, allowing us to target the desired level of complexity for each dataset.

3. Miljöeffektsbedömning av två processlösningar för dricksvattenproduktion
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Norrvattens vattenverk Görvälnverket är beläget i Järfälla kommun och renar vatten från Mälaren. Enligt regionala utvecklingsplaner kommer en ökning av antal anslutna personer till Norrvattens distributionsnät att ske fram till år 2050, således behöver en ökad mängd dricksvatten produceras.

4. Barriers of Traveling with Sustainable Transportation Vehicles : A comparative empirical analysis of leisure travelers’ behavior in Sweden, Germany, and Iran
Master-uppsats, Umeå universitet/FöretagsekonomiSammanfattning : This master thesis analyzes the influence of psychological barriers of consumers from Germany, Sweden, and Iran for using sustainable transportation modes. Climate change has started to change the way people travel. LÄS MER
5. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. LÄS MER
