11. Comparing different methods of measuring particle size for pharmaceutical excipients
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

12. LES modelling of spray combustion
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

13. Information Engineering with E-Learning Datasets
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The rapid growth of the E-learning industry necessitates a streamlined process for identifying actionable information in the user databases maintained by E-learning companies. This paper applies several traditional mathematical and some machine learning techniques to one such dataset with the goal of identifying patterns in user proficiency that are not readily apparent from simply viewing the data.

14. Identification of Neutrons Using Digitized Waveforms
University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : The advantages of performing neutron-tagging measurements using a waveform digitizer are explored. An existing analog setup consisting of modular crate electronics at the Source-Testing Facility at the Division of Nuclear Physics in Lund, Sweden has been digitally replicated. READ MORE

15. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. READ MORE
