1. 21. Lusus Poeticus vel Musicus : Johann Sebastian Bach, the Baroque Paragram and Friedrich Smend's Number Alphabet Theory

   Författare :Ruth Tatlow; Arnold Whittall; London university; []
   Nyckelord :HUMANIORA; HUMANITIES; Bach; Number alphabet; Germanistics; Baroque literature; Music; Musikvetenskap; Musikvetenskap; Musicology; Idé- och lärdomshistoria; History of Sciences and Ideas;

   Sammanfattning : The starting point of this investigation was Friedrich Smend's number alphabet theory. Contrary to current trends in the analysis of Bach's music, Friedrich Smend used an eighteenth-century technique to understand eighteenth century music. LÄS MER

3. 22. Volatility and number measurement of diesel engine exhaust particles

   Författare :Hanna Bernemyr; Hans-Erik Ångström; Nigel Clark; KTH; []
   Nyckelord :particle emissions; measuring methods; particle number measurements; dilution; rotating disc diluter; v-TDMA; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. LÄS MER

4. 23. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions

   Författare :Qingshuang Fan; Förbränningsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent premixed combustion; Ammonia flames; Laser diagnostics; Flame structure; High Karlovitz number; Turbulent burning velocity; Fysicumarkivet A:2021:Fan;

   Sammanfattning : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

5. 24. The Integration of MILLION into the English System of Number Words : A Diachronic Study

   Författare :Donald MacQueen; Merja Kytö; Raymond Hickey; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; number-word universals; historical corpus linguistics; variationist study; American vs British English; newspapers; grammaticalization; iconicity; gradience; English language; Engelska språket; Linguistics; lingvistik;

   Sammanfattning : This corpus-based variationist study traces the history of the English number word MILLION from its first attested use in the 14th century, focusing on the diachronic shift in function from one of heading its noun phrase (NP), as in the obsolescent (Obs) construction three millions of citizens, to one of a post-determiner of its NP head, as in Present-day English (PdE) three million citizens. The authentic historical materials used include both numerous electronic linguistic corpora and, more innovatively, very-large-scale general collections available online, especially historical newspaper collections from the US and UK comprising tens of billions of words.

7. 25. Structure of Zero Pressure Gradient High Reynolds Number Turbulent Boundary Layers

   Författare :Murat Tutkun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fourier decomposition.; proper orthogonal decomposition; large scale structures; Turbulent boundary layers; zero pressure gradient; wind tunnel; calibration; cross-correlations; hot-wire; two-point correlations; high Reynolds number;

   Sammanfattning : This thesis presents part of the large research program funded by the European Commission calledWallturb: A European synergy for the assessment of wall turbulence. The main aim of this researchprogram is to create new experimental and numerical databases on the characteristics of turbulent wall-bounded flows, especially turbulent boundary layers. LÄS MER
