1. 26. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced composites

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Jiacheng Lin; Haoran Teng; [2019]
   Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification.; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

   Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

3. 27. Paradigm Shift : The musical developement of barbershop harmony between 1939-2018

   Uppsats för yrkesexamina på grundnivå, Kungl. Musikhögskolan/Institutionen för musik, pedagogik och samhälle

   Författare :Rasmus Krigström; [2019]
   Nyckelord :Barbershop; Harmony; Musical Development; Genre-specific; barbershop; stämsång; musikalisk utveckling; genrespecifik;

   Sammanfattning : Barbershop harmony in the form of quartet singing has its roots in the USA from the middle of the 19th century and has grown into its own unique genre. Towards the end of the 1930’s the genre had almost disappeared, and in 1938 an organization was formed to preserve it. LÄS MER

4. 28. Numerical Modeling of Aluminum Sampling Process

   Master-uppsats, KTH/Materialvetenskap

   Författare :Ming Yang; [2019]
   Nyckelord :Numerical modeling; Aluminum sampling; Solidification process; Inclusion distribution; Ansys Fluent.;

   Sammanfattning : Castings of aluminum alloys are widely used in the automotive and aerospace industries since they play a significant role in improving the performance and fuel efficiency. In aluminum industries, sampling is the most common method to evaluate the inclusion levels which is a key indicator for the quality of the aluminum alloys. LÄS MER
